Both alloy thermo-seed and radiation seed implanted by magnetic induction hyperthermia are at the same level with the scale. When the thermo-seed and radiation seed implant into the tumor tissue at the same time, thermal field and radiation will act together on the tumor cells, enhancing the destruction effect of tumor cell. The electromagnetic theory is applied to calculate the heat production power by thermo-seed and radiation seed in the RF magnetic field; and the thermo-seed and radiation seed are placed with different distributions into the RF magnetic field of the magnetic induction equipment in order to examine the temperature rise curve under various conditions by adjusting the magnetic field parameters. The heating effect of radiation seed in the RF magnetic field are studied in order to verify the safety of the radiation seed; with alloy thermo-seed and radiation seed are in a mixed configuration, the heating effect is studied in order to verify the effectiveness of the combined therapy. The theoretical calculations indicate that the magneto-caloric effect of radiation seed source in the RF magnetic field of magnetic induction therapy (50~500kHz) is insignificant, and the safety of hyperthermia and radiotherapy has been verified. When radiation seed mixing with thermo-seed are implanted into the agar model and the muscle tissue in vitro, the temperature in the media implanted area is far above 43℃, realizing the sensibilization that hyperthermia has on radiotherapy in the implanted-area.

This paper presents the design and the realization of an ARM-based fly task control system in the UAV, guided by small TV and with the ability of attacking and scouting. As a central part of the UAV, this system utilizes the PHILIPS ARM7-LPC2138 and has embedded the real-time operating system USOS II to accomplish the task of both the real-time data exchange and data treatment with other four subsystems. The data exchange between the ground station and the system is achieved through the interface with the data link radio; the target tracking and locking is achieved through the interface with the TV control system; the flying path control under the condition of the locked target is achieved through the interface with the flight control system; the control of the TV control system is achieved through the interface with the Pan/tilt and the camera. The data exchange is stable and reliable with the error rate lower than 0.1%. The system controls of the Pan/tilt can meet the requirements of speed, veracity and stability. The control angle of the path deviation is accurate and it is transmitted to the flight control system. At present, the development of the prototype is completed, with test flights and simulated attacking experiments to provide technical supports for the large-scale UAV with the abilities of attacking and scouting.

The Nanfen iron deposit is the largest open-pit iron deposit not only in China but also in Asia. Since 1949, it has become the main mine to provide high grade iron for the Benxi Steel Iron Cooperation. This paper discusses the geological background of the mineralization the geological characteristics and the major and rare earth elements in the Nanfen iron deposit. The major and rare earth elements (REE) of banded iron formations are analyzed and it is shown that the average bulk compositions of banded oron formations (BIF) are rich in Fe and SiO₂, but with very low Al₂O₃ and TiO₂ contents, as consistent with the characteristics in Anshan-Benxi, Wutaishan and Qianshan. These chemical features show that they are chemical sediments of detrital input, with very low REE concentrations, with the shale-normalized REE patterns of distinct positive anomalies of Eu and the depletion of light REE relative to heavy REE. This demonstrates that the BIFs are the products of chemical sedimentions from the paleo-seawater with significant input of volcanic hydrothermal fluids.

At the end of the early Permian, the volcanic activities have a great impact on the formation and the evolution of the underlying Carboniferous hydrocarbon in the central Tarim. The volcanic activities promote the maturation and the hydrocarbon expulsion of the source rock; and also help the conducting systems to develop, such as the fault and the crack, meanwhile, make it possible to form different types of reservoirs such as the neck piercing and the volcanic dike lateral occlusion reservoirs; moreover, the volcanic activities can deform the original reservoirs to form secondary hydrocarbon reservoirs. This paper uses drilling, logging, seismic methods (including seismic attributes, reflection configurations and time slices) to identify and predict the Carboniferous volcanic rocks and the plane distribution characteristics of the volcanic rocks in the central Tarim. It is shown that the volcanic rocks in the central Tarim are mainly output in the form of the laccolite and the rock wall, and the intensity of activity gradually weakens from northwest to southeast. What is more, the thickness from the northwest to the southeast gradually decreases until check out. This study may provide some guidance for the rolling exploration and the development of petroleum in the central Tarim.

In order to mine the insulating pillar of Dongguashan copper mine safely and effectively, with the full use of existing mine roadways, new ore-drawing roadways are needed to be excavated under the filling of the panel stope. Based on the theory of the surrounding rock released zone, the roadway surrounding the rock released zone is measured by the single-hole acoustic detector, to provide the basis of the determination of the roadway roof safety thickness and the support pattern. By means of field tests, the surrounding rock released zone thickness of -760m and -790m levels is 0.8~1.3m. Combining the Saint-Venant principle and the field experience, the roof safety thickness of the new extracted ore-drawing roadway under filling is determined to be 4m. In addition, the shotcrete-bolt support pattern is adopted; as regards to the partial broken area, the spray anchor net united support pattern is adopted. As a result, when the length of the bolt for the new extracted ore-drawing roadway is determined to be 2.2m, and the grid is 1.0m×1.0m, the roadway surrounding the rock released zone can safely and economically be controlled.

Rock burst often occurs when burst-prone rocks meet higher bearing pressure. In order to control the rock burst, based on the distribution of bearing pressure, the borehole deformation and blasting vibration are used in order to shift the peak bearing pressure to the deep rock mass, and to release some concentrated stress, therefore to increase the carrying capacity of decompression zone. Construction parameters controlling rock burst and the prevention measures for the drilling tool from jamming are obtained by using the field burst tests on tunnel, ingate, and shaft excavation. Test results show that it could successfully control the rock burst at the front end, when the ratio of crossing over cycle to excavation depth reaches at 2~3. And a triangular arrangement of super-deep hole is able to resoundingly control the rock burst in tunnel, ingate and shaft excavation face. In addition, the interval of 1.5~2.5m layout plus the deep vibration hole of 2.0 ~3.0m is able to successfully control the rock burst in the tunnel waist wall or in the wall of a shaft well. And then smooth blasting or bench smooth blasting with temporary rock bolting is able to avoid roof fall or wall caving in the ingate.

In the northwest margin of Junggar Basin Wuerhe, two sets of reservoirs including the dolomitic rock and the volcanic rock are developed in Permian Fengcheng Formation. An analysis of the distribution range of the dolomitic rock reservoir is very important for the petroleum exploration in the study area. However, these two rocks have the same seismic reflection, so they cannot be distinguished only by using the amplitude data. In this paper, the spectral decomposition is used to analyze the difference between the dolomitic rock and the volcanic rock so as to distinguish their distribution range. Then according to the actual well test data, the relations between the deliverability of the reservoir and the spectral parameters are obtained. Based on the relations, the spectral property is extracted to predict the distribution range of the high quality dolomitic rock reservoir, to provide a technology support for the exploration of Permian Fengcheng Formation in this area. The method of using spectral decomposition to predict the high quality dolomitic rock reservoir can also be used for studying the dolomitic rock in other areas.

In engineering applications, the fracture of the thermowells caused by resonance becomes more and more an important issue. But most studies were limited to the resonance frequency and very few were concerned with the stress analysis at points of resonance or away from resonance for the thermowells. So far there is no comprehensive solution. Based on the specifications of ASME PTC19.3 TW—2010, this paper establishes relevant limits by analyzing the vibration frequency, and the steady-state static and dynamic stresses in the thermowells. A design method of the thermowells for engineering applications is proposed, and the specific procedures of the calculation and the evaluation are shown through an actual example. It is shown that this method can ensure the safety of the themowalls in engineering applications.

The large scale nonlinear optimization has become a research focus in the planning, the interior-point algorithm is an effective method for solving large-scale inequality constraints, however most of the filter interior-point algorithm only consider the feasibility and stability, ignoring the adjuvant on the performance of algorithm, so that in this paper, in the light of the Karush-Kuhn-Tucker (KKT) conditions of the interior-point algorithm, a new algorithm, with feasibility, auxiliary and stability as the objective of the search step, use the amount of the violation of equality constraints, the obstacle objective function and auxiliary conditions as a filter option to calculate the search step and build a computer simulation environment for the numerical test, compared with the basic filter method from the number of iterations, function estimated times and run time. The test results show that under the same conditions the new algorithm, compared with the basic filter method, can get more search steps, and achieve fast convergence, having good global convergence, robustness and effectiveness.

To test the cooling performance of a Fan Coil Unit (FCU), a large amount of experiment has to be carried out, which is both time-consuming and energy-consuming. To solve this problem, in this paper, the grey system theory is used to establish a GM (1, N) grey model representing the relationship between the FCU volume and such parameters as the frozen water temperature, the cooling water volume and the wind temperature, to predict the FCU cooling performance under various working conditions. The results show that both the simulation and the estimation are satisfactory, and the method provides, a scientific and effective way for FCU enterprises and testing departments to estimate the working condition characteristics of new batches of FCU with only a few (5 to 6) typical experimental data and with the historical data of working conditions, thus to reduce the test time and the energy consumption to less than 5% of those by using the traditional method, and to enhance the FCU characteristics testing work efficiency by 20 times.

To provoke an immune response against HBsAg in chronic HBV infections for interrupting the infection processes has been the purpose of therapeutic HBV vaccine. The vaccines research is basically the biological agents with the immunogenicity of HBV HBsAg. Due to the DNA sequence, the molecular structure and immunogenicity of HBsAg in HBV have no connection with those of HBV HbeAg at all; the HBeAg is a free and non-membrane antigen, therefore the anti-HBeAg response has no effect on the immune clearance reactions of HBV and infected hepatocytes in chronic HBV infections. Up to now, only with the clinical data about HBeAg system in serum with patients studied in Phase II clinical investigation, the treatment effectiveness of therapeutic HBV vaccine is still unable to be determined. The applications of vaccines is prophylactic in the sense of preventing viruses or bacteria from invasion, however the effort of therapeutic vaccines is that develops immune responses against persistent viral infections in an immune tolerant situation after exposure. It still remains a vision without the support from scientific rationale. Under the conditions of liver cells widespread infected by HBV in chronic HBV infection, while the anti-HBsAg response had been provoked with the treatment of therapeutic vaccine in these individuals, the free virus and HBsAg antigen particles in serum might be cleared, even the infected liver cells should be directly attacked as with accompanying circumstances, the degree of liver damage associated with the immune pathology as well as a corresponding risk could not possible estimate because of the infected degree of liver cells is hard to be estimated before chronic HBV infection treatment. Since the applications implicate such a risk, it is one of the important factors for the therapeutic HBV vaccine that is unable to get out of the laboratory. The future of therapeutic HBV vaccine seems doomed unless new and applicable immunologic principles are discovered.
