Therefore, the LsHNXs genes were cloned in this study, and their function was studied by RNAi. The main results were shown as follows:1 The conservative sequences of three LsHNXs genes (LsHNX1, LsHNX2, and LsHNX3), and the 3'-terminal specific sequences of LsHNX2 and LsHNX3, were cloned by RT-PCR and 3'-RACE.2 The plant RNAi vectors were constructed and the transformation of Limonium sinense was done. The RNAi lines of three single-genes and one double-gene were obtained and were propogated rapidly for the molecular and the stress tolerance analysis.3 To be compared with wild type, the Na+ and K+ contents secreted by the leaves of LsNHX1 transgenic plants were remarkably higher.

Both upper and lower dental study models were collected from 30 boys (12 years old) and 30 girls (12 years old) with acceptable normal occlusion to understand the characteristics of the crown size, dental arch width and length such as (1) mesiodistal diameters of crown size from central incisor to first molar,(2) the width and length of dental arch and basal arch and (3) the morphology of dental arch form. After statistical analysis, data were compared with Japanese, Central and South American Indians and North American Caucasians from papers. The results were:(1) There was no statistical difference in teeth size between males and females, except the upper first molar of males was larger than that of females, lower central incisor of males was smaller than that of females.(2) The dimensions of dental arch of males were larger than that of females in general, especially such items as width and length of basal arch.(3) The crown size of Chinese male was in generally smaller than that of four other races, especially the upper canine, lower central incisor and first molar.

By use of titration analysis, the thesis investigated various factors such as isocyanate, PE molecular weight, reacting substance molecular ratio, reacting temperature and time etc. influencing upon prepolymerization step. It was found that 2, 4-tolulene diisocyanate and 4, 4'diphenylmethane diisocyanate is more rapidly reacted with PE600 than HDI. With PE molecular weight increasing, the reacting temperature or time should be raised or extended relevantly. Thus PE2000+2HDI pre-polymerization should be better carried out under some catalyst, for example, Triethylene diamine , Dibutyltin dilaurate and Tin octoate were used.
首先采用滴定分析方法对WRPU预聚反应的影响因素进行了研究:芳香族二异氰酸酯TDI、MDI比脂肪族二异氰酸酯HDI反应活性高,其中TDI在反应初始阶段的反应速率比MDI快,不过随着反应的进行,MDI比TDI反应速率加快,这主要是因为TDI分子中的两个-NCO反应活性差异大所致;二元醇分子量越大,反应速度越慢;聚醚二元醇比聚酯二元醇的反应速度快;当分子量超过2000的二元醇与HDI进行预聚反应时,需借助适当的催化剂来加快反应速度,从而使预聚反应能够顺利进行,分别选择DABCO、TOA和DBDTL三种催化剂进行催化反应,发现不同的催化剂,其催化效果相差较大。
