Abstract ( 260 )
With the high penetration rate of wind power,Jilin province is now facing a severe bottleneck in wind power accommodation,which has seriously restricted further development and utilization of wind energy resources.The factors causing the bottleneck include fluctuation of wind power,load level of power grid,and heating demand in the winter season.In order to solve the problem of wind power curtailment,development of intelligent wind power dispatching system which is suitable for strongly fluctuating power supply,and utilization of emerging technologies,such as thermal energy storage technology and wind-energy heat supply technology,to improve the regulating capacity of power grid and increase the scale of electric load are two effective ways.According to the present situation of large-scale wind power integration of Jilin Province,this paper introduces the current situation and existing problems of wind power forecasting technology,thermal energy storage technology and wind-energy heat supply technology,and expounds the application and development trend of these key technologies for wind power accommodation.

Abstract ( 487 )
To deal with the difficulty in radar signal processing,effective and efficient detection of low-observable targets in complex environments is an ongoing research hotspot.On the one hand,due to strong clutter and complex motion of a target,the signal may be extremely weak such that it is hard to detect the signal either in time domain or in frequency domain.On the other hand,the signal resources of traditional radar are limited and cannot achieve refined description of the target itself.Therefore,it is urgent to develop new system and technology for radar target detection.In this paper,we firstly summarize the main difficulties for low-observable target detection.Then,we systematically review conventional radar moving target detection methods.Finally,we discuss the future development from the perspective of detection techniques and systems.

LI Yubao, XIA Jinmeng, LUN Dongdong
Science & Technology Review. 2017, 35 (11): 47-51. ;  doi: 10.3981/j.issn.1000-7857.2017.11.006

Abstract ( 132 )
Heavy metals in soil stem from human activities which result in significantly high heavy metals contents in soil and lead to the phenomenon of ecological environment quality deterioration.Heavy metal contamination of soil is essentially an irreversible process.Many organic chemicals require a long time to degrade.Once contamination occurs it is difficult to recover by merely cutting off pollution sources.Therefore there have been a lot of soil treatment methods for heavy metals.Compared to physical and chemical remediation,phytoremediation has several advantages such as small investment,low cost,economical profit and less disturbance to the soil environment.This paper reviews four hytoremediation techniques for heavy metal contaminated soil remediation and describes both domestic and foreign heavy metal pollution control.Finally,the future development in this area is prospected.

Abstract ( 354 )
Chinese acupuncture is a treasure of the ancient Chinese science.Evidences show that acupuncture can transmit signals through stimulating body surface to the brain where the signals are integrated and sent to the whole body,so as to regulate organs'function through the neuro-endocrine-immune system,improve human body harmony and treat diseases.Nowadays,neuromodulation technique represents a trend.In the U.S.the program of stimulating peripheral activity to relieve conditions (SPARC),which is similar to electro-acupuncture,has been conducted at the National Institutes of Health (NIH) since 2016.In this article,we briefly summarize the current situation of acupuncture and brain-related studies in both traditional Chinese medicine and modern medicine,and try to explore the therapeutic mechanisms of acupuncture from the perspective of neuromodulation.Understanding the operational mechanisms of acupuncture from the central and peripheral nerve systems will be of great significance to the AI development on account of acupuncture neuromodulation in the future.

Abstract ( 468 )
Through collection and analysis of relevant literature,the contents of heavy metals lead,arsenic,cadmium and mercury in Chinese herbal medicine are statistically analyzed under the ISO international standard of “Chinese medicine-Chinese herbal medicine heavy metal”.It is shown that the four kinds of heavy metals have excess rates of 3.46%,4.03%,2.91% and 1.41%,respectively,being the highest excessive ones in animal species.In addition,flowers,leaves,and whole grass have relatively higher contents of heavy metals,and they are followed by root and rhizome,stems and trees,while fruit and seed classes have the minimum exceeding rates for heavy metals.At present,the limits of heavy metals in various countries and regions are mainly based on plant medicinal materials,and there is no unique limit to heavy metals in animal medicines.Therefore,it is necessary to speed up the research and standard development of heavy metals in animal medicines.
