Four sorts of sex pheromones that were mixed at different ratios with three kinds of main sex pheromone components of seabuckthorn carpenter moth:-7-tetradecenyl acetate (Z7-14:Ac),-3-tetradecenyl acetate (E3-14:Ac) and-7-tetradecenyl acetate (E7-14:Ac), were experimented in the field. The results showed that four kinds of pheromones all had strong, attractive effects on male moths.

After analysis of multiple sequences alignment, phylogenetic tree and similarity of sequences, it was shown that Ac-ASP has similar relation with Am-ASP, and shared high homology with other Hymenopteran and Coleopteran. From above analysis, we firmly suggest Ac-ASP1 and Ac-ASP2 belong to OBPs family and Ac-ASP3 belong to CSPs family.

通过多序列联配、系统发育树及序列相似性分析，Ac-ASP除与西方蜜蜂Am-ASP亲缘关系较近(相似性达到80％以上)外，与其它膜翅目以及鞘翅目的OBPs及CSPs也有一定的亲缘关系(相似性达到30～60％)，且Ac-ASP1和Ac-ASP2应为OBPs，Ac-ASP3则应为CSPs； 4。

The EAG responses of the male black cutworm moth, Agrotis ypsilon to standard chemicals of sex pheromone, i.e., Z7-12: Ac, Z9-14: Ac, Z11-16: Ac, Z5-10: Ac and Z8-12: Ac, were measured.

利用触角电位记录技术，测定了小地老虎Agrotis ypsilon雄蛾对性信息素标准化合物Z7-12：Ac、Z9-14：Ac、Z11-16：Ac、Z5-10：Ac和Z8-12：Ac的EAG反应。

This article first on to the topic background, the topic object basic survey and the topic research goal has given brief showing, then has made a detailed elaboration to the AC-DC-AC inversion principle of work, emphatically has analyzed based on the AC-DC-AC inversion control principle as well as the SPWM profile several productions method.

本文首先就对课题的背景，课题对象的基本概况以及课题研究的目的做了简要的说明，然后对AC-DC-AC逆变器的工作原理做了一个详细阐述，着重分析了基于AC-DC-AC逆变器的控制原理以及SPWM波形的几种生成方法。

All iliac hone graft fused well and a great deal of bony callus was found the vertebral body surface. Lucency area was in seen surrounding the hone graft, titanium and AC-AFF on the X-ray films, and there wan new bone formation in the interface of internal union and bone. The central region of titanium and AC-AFF became vague and new bone formation was found in the intracavitary aim of implants by CT scan. And port of the new hone transited the parietal reticulation and connected with normal ones at titanium and AC-AFF.

髂骨植骨组融合情况良好，融合界面上有较多的骨痂生成。X线摄片见植骨块、钛网、AC-AFF中空区域模糊且有骨组织生长，内植物周围无透光带存在，植骨界面上有骨桥形成；CT扫描在钛网及AC-AFF组可见内植物腔内形成的新骨通过其四壁的网眼结构与周围骨质相接，说明所有标本均达到骨性融合，但其中以AC-AFF组形成的新骨数量为多，且较为成熟。

AC Test Power Supply with AC-DC-AC conversion means, effectively prevent the mains voltage and frequency fluctuations of the dielectric loss test the accuracy of the impact of even the generator, the instrument can also be run correctly.

交流试验电源采用AC-DC-AC转换方式，有效避免市电电压及频率波动对介损测试准确性影响，即便是发电机发电，该仪器也能正确运行。

An apparatus simulating the discharge in AC PDP cell is thus designed. It consists of a driving power, discharge cell and vacuum system. Measuring are made possible on the working voltage and stability of dielectric protective film made from different materials with a variety of different processes. The secondary electron emission property can thus be properly reflected. Examinations are also the gas species, mixture composition ratio and pressure, discharge gap, etc., with reference to the discharge characteristics in AC PDP.
