1·The contents of soil alkali hydrolyzable nitrogen were increased by plant urease inhibitor under two cultivated condition.

植物性脲酶抑制剂能提高两种作物的土壤碱解氮含量。

2·And it could improve the contents of organic matter, alkali - hydrolyzable nitrogen, available phosphorus and potassium in soil.

土壤中的有机质、碱解氮、速效磷、速效钾的含量均比对照增加。

3·The content of simple phenols and hydrolyzable tannins were very low and their variations were not significant during autumn and winter.

试材枝内简单酚类物质和可溶性单宁含量极低，且在秋冬季节无显著变化。

4·The content of the hydrolyzable chlorine ino -cresol -novolac epoxy resin (ECN) is an important factor which influences the quality of the resin.

ECN树脂中的可水解氯含量是决定树脂质量的—个重要指标。

5·Hydrolyzable chlorine gives harmful effects on solidification behavior and solidified products performances for epoxy resins, and thus be an important quality index for the title product.

可水解氯会对环氧树脂的固化行为与固化产物的性能产生不良影响，因而其含量是环氧树脂一项十分重要的特性指标。

6·The forming mechanism of hydrolyzable chlorine and its industrial reducing technology have been explored, with bisphenol a epoxy resin, by the author. And an effective way has been found.

本试验以双酚a型环氧树脂为例，对可水解氯的形成机理以及降低其含量的工业化工艺路线作了探索，找到了有效的降氯方法。

7·Exceptions did exist, especially with alkali-hydrolyzable n, readily available p, readily available k, and micro-elements, which sometimes altered inconsistently with the above-said patterns.

但也有例外，尤其是碱解n、速效p和速效k以及微量元素，有时出现与上述规律不一致的情况。
