In this paper,the behavioral,physiological, ecological adaption mechanism of H.armigera and H.assulta to their common host plant tobacco were studied comparatively,and the main results were summarized as follows:Electroantennogram response of adult to tobacco volatiles:(1) H.armigera and H.assulta elicited similar EAG responses to the tested 20 tobacco volatiles;both of them elicited significantly more sensitive to green leaf volatiles,aliphatic and aromatic compounds, than to monoterpene,sesquiterpene,heterocyclic compounds under lower concentration; while the similar EAG responses under higher concentration were detected,but most of them were not significantly different with each other.

本文从行为、生理和生态适应三个方面，对棉铃虫和烟夜蛾与烟草间的互作进行了比较研究，主要结果如下：成虫对烟草挥发物的EAG反应：(1)两种夜蛾对测试的20种烟草挥发物均可产生EAG反应；低浓度下对绿叶气味、脂肪族、芳香族化合物的EAG反应显著高于单萜类、倍半萜类和杂环化合物；高浓度下的EAG反应也表现出相似的总体反应趋势，但多数反应值间的差异未达显著水平。

The antitumor effects of sesquiterpene lactones scabertopin and isodexyelephantopin from the whole plant of Elephantopus scaber were studied in vitro on SMMC-7721,Hela and Caco-2 cancer cell lines.

采用四甲基偶氮唑盐比色法和琼脂糖凝胶电泳法等研究地胆草倍半萜内酯化合物scabertopin(1)和isodeoxyelephantopin(2)在体外对SMMC-7721、Hela和Caco-2三种肿瘤细胞增殖的影响。

The classes of these compounds included triterpenoid, diterponid, sesquiterpene, steroid, lignan, flavone, coumarin, phenol, and fatty acid.

已鉴定的化合物类型涉及单萜、环烯醚萜、倍半萜、二萜、三萜、木脂素、黄酮、脂肪酸、甾醇、香豆素、酚酸和其它类型的化合物。

5S-160GP/9T-160 consists of a main case driven by 3-shaft fixed spindle and a rear mounted auxiliary case driven by planet gears. The main case has 5 forward speeds and 1 reverse speed. The auxiliary case has 2 speeds which double the speed of the main case, so that the transmission has 9 forward speeds, the 4 forward speeds of main case shift by ZF-BK short travel synchronizer, auxiliary case shift by lock ring synchronizer, crawler and reverse shift by join sleeve powered by the engine of 280-380 hp.

5S-160GP/9T-160型变速器由三轴传动的主变速器和后置的行星齿轮传动副变速器组成，主变速器有五个前进档和一个倒档，副变速器有两个档位，可将变速器的档位增加一倍，故变速器具有九前一倒档，主变速器4个前进档采用ZF-BK型短行程同步器换档，副变速器采用锁环式同步器换档，爬档和倒档采用接合套换档，用户可根据需要选装部分功率取力器N71 /1或N71/2， N70。
