The effect of crude chitinase on three pathogens showed that it could degrade the cell-wall of thepathogens.The crude chitinase could make Fusarium spp and Alternaria spps cell-wall thin andrupture,cell-wall and bioplasm separate,the bioplasm of Rhizoctonia solani distribute asymmetry andbecome vacuole,the cell-wall thin and rupture also.

几丁质粗酶对三种病原真菌菌丝细胞壁的降解作用显示，几丁质酶可使交链孢和镰刀菌菌丝细胞壁变薄、溶解、质壁分离、原生质膨大；丝核菌原生质体分布不均匀、空泡化、细胞壁变薄并出现断裂现象。

The results show that 5% nucleating agent,twelve-hydrated disodium hydrogen phosphate,could reduce the supercooling degree of acetate hydroxide trihydrate to some extent but the supercooling degree was still large.However,the supercooling degree of sodium acetate trihydrate could decrease clearly by adding 3% thickener gelatin and 5% twelve-hydrated disodium hydrogen phosphate.

实验结果表明，质量百分比为5%的成核剂十二水磷酸氢二钠能一定程度上抑制无机水合盐三水醋酸钠的过冷度，但其过冷度仍然较大；使用质量百分比5%的十二水磷酸氢二钠和质量百分比3%的增稠剂明胶做添加剂后，三水醋酸钠的过冷性能得到明显改善。

The results indicated that the exterior traits for seeds were controlled by endosperm, cytoplasm and maternal genetic effects.

结果表明，种子外观性状的表现同时受制于胚乳核基因、母体植株基因和细胞质基因三套遗传体系。

On the basis of these principles and requirements,in this paper,a new modifier has been synthesized from pyromellitic dianhydride and thiosemicarbazide by the nucleophilic addition of anhydride,the cyclization of acyl thiosemicarbazide in alkaline solution,and the N-hydroxymethylation of the triazole-thione.

本文根据这一思路，以均苯四甲酸二酐和氨基硫脲为起始原料，通过酸酐的亲核加成反应、酰氨基硫脲的碱性环化反应、三唑硫酮环的N-羟甲基化反应合成出了一种新的N-羟甲基三唑硫酮酸改性剂。

Given that the proposed section 39F(1) provides that a member of the Assessment Board is to hold office for a term not exceeding three years but may be reappointed, it was proposed that section 39F(1) be amended such that the Panel members would also be appointed to hold office for a term not exceeding three years, but may be reselected.

鉴于建议的第39F（1）条规定，评核委员会的成员的任期不得超过三年，但可再获委任，因此我们建议修订第39F（1）条，令备选委员小组的成员获委任的任期也是不得超过三年，但可再被挑选。
