Recent Experimental Progress in the HT-7 Tokamak

Recent experimental campaign in the HT-7 toka-mak was scheduled to be ran from November 2002 toMarch 31, 2003, during which various issues were in-vestigated on getting high electron temperature, longpulse discharges and high performance plasma underquasi-steady-state condition. New systems includ-ing LHCD launcher, cryogenic compressor, real-timepoloidal control, water-cooled toroidal belt limiter,ferretic liner and several diagnostics were installedand operated to satisfy long-pulse operation require-ments. The maximum total injected power was over1 MW and the longest discharge duration was nearto 64 s.

PROGRESSES MADE IN EXPERIMENTAL STUDIES OF SHALLOW-WATER ACOUSTICS

Acomprehensive experiment on shallow water acoustics with the inseparable combination of the acoustical and oceanographic means, which is uncommon internationally, was conducted successfully in the Far Yellow Sea by a group of Chinese and U.S. scientists from August 21 to September 1,1996. The basic task of ocean acoustic research is to study the interaction between sound wave and ocean media, which includes exploring the laws of influence due to spatial and temporal variability of the ocean environment, such as ocean surface waves,inhomogeneity of sea water and sea bottom struc-

Advances in porous volumetric solar receivers and enhancement of volumetric absorption

Porous volumetric solar receivers are one type of solar receivers that can volumetrically absorb solar radiation and achieve efficient solar-to-thermal energy conversion.Porous volumetric solar receivers have been developed since 1980s.In this review,we focus on the development progress of the atmospheric and pressurized porous volumetric solar receivers,in which the structural designs,the material selections,the experimental research methods,the comparison of thermal performance,and the transient response characteristic of the receivers were reviewed.On the other hand,the theoretical research methods including the direct pore-scale and volume averaging simulations were introduced.The pore-scale reconstruction method and the procedure to investigate the fluid flow and heat transfer processes at the pore-scale were presented.For the volume averaging method,detailed descriptions for the selection of empirical parameters in the governing equations to be solved were summarized.Typical research results based on these methods were presented and research limitations were also pointed out.Furthermore,the methods for the enhancement of volumetric absorption and the improvement of thermal efficiency of the receivers have been comprehensively reviewed.Two methods including geometrical parameters optimization and spectrally selective absorption were presented in detail.This review will provide a better understanding of the development and research methods for porous volumetric solar receivers,and inspire future studies for the performance improvement of the receivers.

艾灸肝脏效应及其影响因素的实验研究进展

Through retrieving the relevant experimental researches from Pubmed,CNKI,Wanfang and VIP databases,it is discovered that the effects of moxibustion on liver are mainly reflected in the following three aspects,namely,maintaining the normal functions of liver,promoting the repair of liver injury and delaying liver aging.By further analysis and in view of experiments,the factors influencing these effects may include stimulation site,stimulation intensity and heat source.The effects of moxibustion on liver and its influencing factors are explored and discovered in the perspective of experimental researches and these discoveries have been verified in clinical practice correspondingly.Based on the current study situation,moxibustion therapy is still limited in clinical studies on liver disorders as compared with the experimental researches.Hence,the deep exploration of moxibustion on its specific biological effect and mechanism and the excavation of moxibustion on its clinical application are likely to be the coming emphasis of the basic research and clinical practice for moxibustion.

Recent Highlights of Chinese Medicine for Advanced Lung Cancer

Owing to its unique superiority in improving quality of life and prolonging survival time among advanced lung cancer patients, Chinese medicine（CM） has, in recent years, received increased attentions worldwide. We utilized a bibliometric statistical method based on MEDLINE/Go Pub Med to conduct a comprehensive analysis of the current application status of CM in lung cancer, by including annual and accumulated publications, origin distribution of countries and journals, and keywords with a higher frequency score. Then the relevant clinical trials and mechanistic studies were systematically summarized within the field according to research types. We have raised potential problems and provided potentially useful reference information that could guide similar studies in the future. The basic experimental results are highly consistent with clinical trials, leading us to conclude that CM can offer better overall therapeutic benefits when used in combination with routine Western medicine for patients with advanced lung cancer.
