The high concentration of salt treatment and the thin alkaline treatment both of whom are used in extracting ribonucleic acid from waste beer yeast were studied in this work.

本文对浓盐法和碱法提取啤酒废酵母中的核糖核酸技术进行了研究，并对这2种方法进行了比较和优化，提出了浓盐法与稀碱法相结合提取核糖核酸的工艺技术路线，酵母中核糖核酸的提取率达90%以上，样品的纯度达90.3%。

The results also showed that the sodium-calcium ratio were different in growth solution of Rumex bucephalopherus under neuter sodium salt and alkali sodium salt condition owing to existence of difference in the Ca〓 level in different growth solution.

从试验还可看出，中性钠盐与碱性钠盐胁迫下，溶液中Ca2+浓度的差异实际表现出钠钙比的不同。

Is an euhalophyte plant in Salicornia, which can tolerate high Na+ concentration.

The following results have been obtained: 1 Expression of SbNHX1 in E. coli enhanced Na+ and K+ tolerances, but not to others; 2 The sequence from 1353-1514bp in SbNHX1 gene played a role for SbNHX1 to Na+ and K+ tolerances; 3 The Na+/H+ antiporter of Salicornia Bigelovii Torr. catalysed Na+/H+ or K+/H+ exchange with equal affinity, which indicates that the SbNHX1 is more likely to locate on member of vacuolar, and responds to transport Na+ into the vacuole from cytoplasm.

证明了SbNHX1能抵抗Na+和K+的胁迫，但对其它盐离子没有抗性；2）证明了北美海蓬子Na+/H+逆向转运蛋白基因（SbNHX1）C末端从基因的C末端1353bp至1514bp的序列在耐盐中起一定的作用；3）证明了北美海蓬子Na+/H+逆向转运蛋白（SbNHX1）对Na+和K+交换的等亲和性，对于这一点，说明北美海蓬子Na+/H+逆向转运蛋白与定位于液泡膜上的Na+/H+逆向转运蛋白的功能相似。

Rubber powder could improve salification erosion resistance, and the more rubber powder, the better salification erosion resistence was. But the effect of rubber powder particle diameter was not obvious.

橡胶粉的掺入提高了水泥土的抗盐蚀能力，且橡胶粉掺量越高，抗盐蚀能力越强，但橡胶粉粒径的影响则不显著。

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。
