The inhibition effect of chloroform fraction was the most potent, with the inhibition rate about more than 83% to 5 plant pathogenic fungi under the concentration of 15mg/mL. Under the concentration of 15mg/mL, the ethyl acetate fraction and n-butanol fraction thoroughly inhibited the growth of Alternaria solani and Valsa mali, with the inhibition rate up to 100%. The n-butanol fraction showed the highest potent virulence, with EC50 to Alternaria solani and Valsa mali about 0.09 and 0.279 mg/mL respectively.

其中氯仿部分的抑菌效果较好，当质量浓度为15mg/mL时，其对5种植物病原菌的抑制率均在83%以上；15mg/mL乙酸乙酯部分和正丁醇部分分别对番茄早疫病菌和苹果腐烂病菌有强烈且稳定的抑制作用，抑制率达100.00%，正丁醇部分对这两种菌丝生长抑制毒力最好，EC50分别为0.090和0.279mg/mL。

There were soluble trophic molecules with relative molecular weight larger than 30 000 for survival and neurite growth of FMN cultures in media with SC-CMCs derived from facial and sciatic nerves of neonatal rats and with SC-CMCs derived from Wallerian degenerating facial and sciatic nerves of adult rats. It might be reasonable to choose SC from sciatic nerves of rats on account of the findings from SC cultures on facial motoneurons.

面神经和坐骨神经SC-CMC中含有促FMN存活、生长的蛋白或多肽，相对分子质量大于30 000，其活性作用与使用的蛋白浓度有关；在研究SC分泌物对FMN营养活性作用时，可考虑选择坐骨神经SC。

One of (1) erroneous zones: After the software development completes carries on the software to test fifth (5) erroneous zone: The project progress becomes serious when little makes a test, the time wealthily when makes tests the object-oriented software performance history and the characteristic object-oriented method of exploitation i.e.

但是，现实情况是，与软件编程比较，软件测试的地位和作用，还没有真正受到重视，对于很多人（甚至是软件项目组的技术人员）还存在对软件测试的认识误区，这进一步影响了软件测试活动开展和真正提高软件测试质量。

The important points in doing research on Web OPAC system are to urge library to increase the service quality, to expand service offerings, to enhance the utilization rate of collected information, as the result, to reflect the value and function of a existing library.

对Web OPAC的研究的重要意义在于它能够促使图书馆提高服务质量，有利于图书馆拓宽服务领域，有助于提高文献利用率，最终体现图书馆存在的作用和价值。

It has ameliorated the basic environment of education, research and management.

作为整个学校管理信息系统的关键子系统之一，它的作用主要体现在：一是为全校的信息管理系统提供重要的教职员工数据，二是可以有效地提高人事管理部门的工作效率和质量。
