The solubility～temperture curve of rubidium hydrogen selenate in aqueous was measured,and the bulk crystal of rubidium hydrogen selenate was grown by solution temperature reduction method after some unfavorable factors such as floating crystals and climbing crystals et al.

本文测定了硒酸氢铷在水中的溶解度～温度曲线，并采用溶液降温法，克服了RHSe晶体生长时易漂晶、爬晶等不利因素，生长出大尺寸硒酸氢铷单晶。

Sodium selenite can induce the apoptosis of SGC7901 cells, which is associated with the blockage of cell cycle.

亚硒酸钠能够诱导SGC7901细胞凋亡，亚硒酸钠诱导SGC7901细胞凋亡与细胞周期阻滞密切相关。

Methods: The DNA damage was measured after L-02 cell were incubated with 80μg/ml sodium fluoride, 1.73μg/ml selenium, 80μg/ml sodium fluoride and 1.73μg/ml selenium using Single Cell Electrophosis respectively.

采用80μg/ml氟化钠、1.73μg/ml亚硒酸钠以及80μg/ml氟化钠和1.73μg/ml亚硒酸钠对培养的L-02细胞进行染毒，24小时后用单细胞凝胶电泳技术检测各组L-02细胞DNA损伤情况。

Na2SeO3 could raise activities of GSHPX in livers and kidneys, promote the effect of antioxidizing system and thus effectively inhibits the mitotic division of vaginal epithelium.

亚硒酸钠可提高银屑病小鼠肝、肾中GSHPX活性，促进体内抗氧化系统的作用，有效抑制阴道上皮有丝分裂，且亚硒酸钠与维生素C可能并无协同作用。

It is proposed that coadministration of carbachol could prevent apoptosis and related alterations in gene expressions induced by sodium selenite just as the carbachol did in the case when apoptosis and related changes in genomic expression were induced by β-amyloid peptide. The facts suggest that apoptosis, at least that induced by two agents tested by us, might be initiated through a similar pathway.

这些结果表明，亚硒酸钠能在较早的时间诱导培养的大脑皮质神经元凋亡，且具有明显的剂量和时间依赖关系；凋亡的引起可能是以亚硒酸钠影响某些特殊基因的表达为基础，其中，c-fos、bax、P53、和bcl-表达的变化主要与细胞凋亡的早期事件有关，而AChE基因表达的增强同凋亡发展的整个过程密切相关。

Results When the cells were treated with Sodium Selenite at a concentration of 2.0mmol//L lasting 72h, karyopyknosis and chromatin condensation were observed under microscope; When the cells were treated with Sodium Selenite at a concentration of 4.0mmol/L lasting 72h, the cells in G0/G1 and S phase was significantly decreased, a typical apoptosis peak before G1 phase was shown.

结果 2.0mmol/L亚硒酸钠作用72h， HE切片可见核固缩、染色质边集等改变；4mmol/L亚硒酸钠作用72h， G0/G1期和S期细胞明显减少，在细胞周期G1前期可见典型的细胞凋亡峰。

Methods Mouse were smoking twice everyday in a self-made passive smoking cabinet, medicative group mouse were given respectively with sodium selenite, vitamin E, sodium selenite and vitamin E for 35 days.

方法小鼠置于自制被动吸烟箱中，每日吸烟两次，用药组小鼠分别给予亚硒酸钠、维生素E、亚硒酸钠和维生素E灌胃，连续35d。

Results When the culture medium was supplemented with 0 .05μg/ml sodium selenite,the proliferation of transformed cells was significant ly promoted and the transformation did not change remarkably,when supplemented w ith 0.25μg/ml,the proliferation was promoted but the transformation was inh ibited,and when with 0.75μg/ml and 1.50μg/ml,the proliferation was not pro moted and the transformation was strongly inhibited.Big dose of (1.50μg/ml) sodium selenite m ade the nuclei of the untransformed lymphocytes gather together like a few grape s doing,and even caused them to fuse.

结果 在培养物中添加0.05μg/ml亚硒酸钠能显著促进转化细胞增殖；添加0.25μg/ml可促进转化细胞增殖，但显著抑制细胞转化；添加0.75μg/ml和1.50μg/ml，不仅不能促进细胞增殖，而且强烈抑制细胞转化。1.50μg/ml剂量的亚硒酸钠使非转化淋巴细胞发生葡萄状聚集甚至核融合。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
