STUDY ON THE BLOOD FAT REGULATION OF THE FUCOIDA—GALACTOSAN SULFATE（FGS） FROM LAMINARIA JAPONICA

FGS was isolated and purified from laminaria japonica by enzymolysis,chromatography methods and so on.The high blood fat model was established by feeding mouse on high fat feedstuff.Compared with control group,the concentration of HDL-C.the ratio of HDL-C.TC increased.while the concentration of TC,LDL-C and TG decreased in experimental groups,Conclusion:FGS was an effective serum lipid regulator and can be developed as medicine and health food.     

剖面不变性与非局部扰动电子温度响应

在ＴＦＴＲ及ＴＥＸＦ等装置上观测到的边界电子冷脉冲的输运现象是通常基于局部热导的瞬态输运理论所无法解释的。利用一个与电子温度剖面不变性相「容的且与在ρ＝ρＬ（ρＬ≈０．７～０．８）处的局部电子热导相关的非局部电子热导模型来描述边界冷脉冲引起的电子温度变化的瞬态过程，发现此模型可定性地解释边界冷脉冲实验现象的几乎所有主要特征。     

STUDY ON THE BLOOD FAT REGULATION OF THE FUCOIDA-GALACTOSAN SULFATE (FGS) FROM LAMINARIA JAPONICA

1. INTRODUCTION Blood fat primarily contains cholesterol, cholesterol ester, phosphatide, triglyceride and free fatty acid in serum of human being and mammalian. Under physiological conditions, the lipids transport in the form of lipoproteins linked with the proteins. Except for the free fatty acid linked with albumin, the other lipids are linked with the globular proteins into high-density lipoproteins (HDL), low density lipoproteins (LDL), very low density lipoproteins (VLDL) and so…

Estimation of the proton energy spectrum in knee region by analog read-out of ARGO-YBJ experiment

Based on the six months data set of ARGO-YBJ experiment with analog read-out and its Monte Carlo simulation,we study the difference between different primaries induced showers by using the space-time information of the charged particles in Extensive Air Showers.With five parameters which can efficiently pick out primary proton induced showers as inputs of an artificial neural network,the proton spectrum from 100 TeV to 10 PeV can be obtained.     

BZ反应的滴定量热研究

用滴定热量计考察丙二酸(以下简称MA)-溴酸钾-硝酸铈铵-硫酸振荡体系在不同反应物浓度下周期、诱导期、诱导期放热的变化情况. 发现反应物浓度与周期、诱导期的倒数之间存在着线性关系,并观测到溴酸钾与丙二酸的浓度固定在不同的值时,随着Ce4 浓度的逐渐变稀,振荡周期变短,从动力学理论角度对上述现象进行了分析.

Experimental Verification of Left-Handed Metamaterials Composed of Coplanar Electric and Magnetic Resonators

We verified experimentally left-handed metamaterials （LHM） composed of coplanar electric and magnetic resonators. A typical LHM sample composed of coplanar resonator unit cells was fabricated, investigated and tested. The experimental results show that the tested sample has a left-handed band of width 1.4 GHz in the X band. The experimental results agree quite well with the simulation ones. Moreover, both the simulation and experimental results show that the LHM under study can automatically achieve good impedance-matching in the left-handed band.
