In order to study the protection of β-carotene and vitamin C against the transformation of human lung fibroblasts cell induced by nickel sesquioxide, HLF cells were treated repeatedly by different concentrations of Ni2O3 in vitro.β-carotene (5.4mg/L) and vitamin C(1.8mg/L) were added into the media containing Ni2O3 (1.0mg/L) respectively. The identification of malignancy of the transformation of HLF cell was carried out by the tests of ConA and the growth on semisolid agar culture. The results showed that Ni2O3 could induce the malignant transformation of HLF cell. The transformed cell proliferated rapidly.

The SMMC-7721 hepatoma cell line of experimental groups and control groups were cultured with the addition of sodium selenite, potassium iodide or triiodothyronine (T3). The cell quantity was checked by the MTT assay , and the cell cycle was observed by flow cytometry and levels of AFP and ALB in the culture solution were determined by RIA.The SD rats were divided into positive control group, negative control group, T3 group and mixture group (the mixture of sodium selenite, KI and T3). After two weeks of the administration of sodium selenite、 KI and T3,Walker256 cells were transplanted into the abdominal cavity. The administration was kept on for another two weeks, then observed the morbility and mortality of the rats with ascites carcinoma. At the end, the ascites were for the cells counting and the cell cycles analysising.

It is indicated that the updrafts of the Arabian Sea meridional cell tube and the south zonal cell tube arrive in the SCS at the same time in May, which brings strong convective precipitation. Meanwhile, the westerly of the meridional cell tube and the southerly of the south zonal cell tube combine together to form the southwesterly at the low levels, resulting in the onset of the SCS monsoon.

研究发现阿拉伯海经向环流管的上升气流和南半球纬向环流管的上升气流在5月份同时到达南海，经向环流管低层的偏西风和纬向环流管低层的偏南风共同组成西南风，于是5月份西南季风在南海地区首先爆发。

The properties of TCC with ATS were as good as the TCC with HTS, better that the requirement of standard GB8744-88 for semi-graphitic carbon block. As good as TCC with HTS in industrial cells, the TCC with ATS also reduces the sodium penetration to cathodic lining, no tear-off of the coating was found after starting up of the cells. As compared with reference cells, the operation of coating cells with ATS was also improved to keep good shape of cell chamber, reduce the formation of sludge on the cell bottom, and gain more uniform current distribution. The ohmic drop of TCC cell bottom was lessened by 11. 5mV. The current efficiency was increased by about 1. 48% in average. It was estimated that the TCC life could be 44 months. Obviously, the TCC with ATS could also improve the performance of industrial cells, save energy, and increase the cell life.

对常温固化涂层槽的考核表明，与高温固化涂层槽一样，阴极内衬对钠的吸收减少，钠渗透速度减缓，从而减小钠膨胀危害，减少了铝电解槽早期破损的几率；启动后，常温固化涂层不脱落，同样具有良好的粘接性能；与对比槽相比较，常温固化涂层槽正常生产后，阴极表面干净、光洁，无沉淀或结壳，炉膛规整，阴极、阳极电流分布均匀，炉底压降降低（平均降低11.5mV），电流效率提高（平均提高1.48％）；涂层在电解槽内存在的时间可达到44个月以上；常温固化涂层同样可以起到改善电解槽工作状态、节能降耗、延长槽寿命的作用。

Virus hasn't cell construction. A lot of simple virus is only made of nucleus acid and protein tegument, so we can regard it as nucleoprotein. A type of virus pill usual has a kind of nucleus acid. After virus infect sensitive host cell, the nucleus acid of virus will enter cell and produce its descendant and new protein by reproduction and expression. Then, the new synthetic virus is made up of descendant that release form cell by regular way. This specific way of reproduction of virus called reproduction.

病毒不具有细胞结构，一些简单的病毒又由核酸和蛋白质构成，故可把它们视为核酸蛋白分子，一种病毒的毒粒内通常只含有一种核酸，病毒感染敏感宿主细胞后，病毒核酸进入细胞，通过其复制与表达产生子代病毒基因组和新的蛋白质，然后由这些新合成的病毒组分装配成子代毒粒，并以一定的方式释放到细胞外，病毒的这种特殊繁殖方式称为复制。

Analysing ustiloxins inhibiting plant cell mitosis The inhibition experiment of growth of garlic radicle showed that there were more cells in the telophase stage in the garlic radicle dealed with culture filtrate of Ustilaginodea virens than those dealed with H2O. The cell volume of the former was bigger than that of the latter. So it seemed that ustiloxins could inhibit the cell mitosis, but not in the cell elongation.
