Cyclic voltammetry indicated that there were Cr→Cr, Cr →Cr oxidation reaction on anode, while there were Cr→Cr, Cr→Cr, Cr →Cr deoxidization reaction on cathode. The graphite electrodes treated by acid and heating could enhance the reversibility and kinetic of the electrode reaction. The nature graphite electrodes had been eroded during charge/discharge process, while the graphite electrodes by activation could avoide corroding by hexad chromium ion. The reversibility and kinetic of the electrode reaction of chromium ion on activation electrode had been increased, so which indicated that graphite surface augment oxygenous function corps which could increase electrode hydrophile capability.

Environment radon is mainly from rock and soil in geological environment, but the research is not connected with geological environment now. On the basis of physical field, the theoretical distribution model of radon in soil and exchange model of earth—air are set up by using Fick diffusion law and Dacy law, and then the research of environment radon is linked with geological environment. This paper described how the evry parameter of the theoretical model influence the radon concentration in air. The results of research indicat that molecule diffusion of radon is different from it's eddy form. Under the condition of surface radon source, the model experiment is used to study the transportation and distribution of radon in medium. The data of experiment show the relationship between radon and depth can be described by exponent. If the radioelement is well—distributtion, the concentration of radon in different depth or in different point at the same depth change with time, but the accumulated exhalation amount of radon at different point on the surface of model are close in relative long time. The author studied the exchange of radon between mediums and verified the theoretical models too.

During the titration of Ca〓CaM by La〓, the hydrid complex La〓Ca〓CaM forms as the intermediate species. La〓 can bind to calmodulin with high affinity (K〓=10nmol/L) and obvious cooperation between the two global domains. The secondary structure of La〓CaM and Ca〓CaM are highly similar, but there are obvious differences in ternary structures. Excessive La〓 changes the conformation of calmodulin greatly.

在辅助加热电弧等离子体发生器的实验中看到:在有外磁场的情况下,主弧弧根在阴极边缘时,弧根有收缩的迹象,而当主弧弧根在阴极中心附近时,观察不到明显的弧根收缩迹象,并拍摄到有双弧柱的图片;当关掉磁场和弧电流〓时,主弧在阴极和阳极之间稳定的燃烧,主弧弧根稳定在阴极中心附近的一点上,而且弧根没有收缩的迹象,主弧弧根亮区的直径约为6.8毫米,与弧柱段的亮区直径相差无几;因而从实验结果分析可以看出,阴极表面温度的升高,能使主弧弧根直径增大:另一方面,由于主弧弧根直径的增大(即也意味着主弧弧根截面积的增大),因而使电弧通过主弧弧根传入阴极表面的有效比热流降低,从而减少了阴极烧损。
