Field experiments demonstrated that efficacy of 30% dichlorvos and omethoate for Caloptilia dentata was over 80%, for Drosicha corpulenta was 95.9% and Psylla willieti 96.4%. For Parathrene tabanifomis, Anoplophora glabripennis, Apriona swainsoni and Panonychus ulmi also gained perfected efficiency, and injection dosage of 2.0ml/cm φ for Myzus persicae obtained 100%result, for Eriococcus lagerostioemiae which damage Punica gianatum the result was 92.96%. In all, the efficiency of 30% diohlorvos · omethoate control of most pests was better than bisultap, decis, acephate, nicotine and avermectin, etc.

田间防效结果表明30%敌畏·氧乐对元宝枫细蛾的防治效果可以达到80%以上，对草履蚧和槐木虱防效分别大于95.9%和96.4%，对白杨透翅蛾幼虫、危害新疆杨和合作杨的光肩星天牛幼虫、危害国槐的锈色粒肩天牛幼虫、危害苹果的榆全爪螨等可达到理想防效，当施药剂量为2.0 ml/cmφ时对桃蚜的防效达100%，对危害石榴的紫薇绒蚧防效可达92.96%以上。30%敌畏·氧乐对大多数害虫的控制作用优于杀虫双、敌杀死、乙酰甲胺磷、烟碱和阿维菌素等。

In this paper, the principle and characteristics of the electro-optic deflection with quadrupole electrodes have been investigated.

随着光信息处理、光学计算机等迅速发展，需要存储、记录和显示异常短暂的物理过程，要求激光扫描技术具有高的偏转速度、分辨率以及扫描参数易控制等性能指标。

The difference between fabrication of binary optic element and that of continuous- relief MOE may not be ignored.A reciprocal equation among the depth,exposure,density of the developer and its etching time was inferred,with the appropriate conditions that proved to be useful for the MOE fabrications.

分析了光刻胶及显影液在制作二元和连续元件中所存在的差别；导出具有倒易关系的浮雕深度表达式和适用的范围，并以此指导面形的控制，对光刻胶进行适当的改造以适应连续微光学元件的制作。

Experimentally, in order to increase the coercivity of the hybrid recording media for increasing the area density, the influences of the magnetron sputtering parameters on the magnetic properties of TbCo films have been investigated.

实验上，围绕着光磁混合记录介质需要具有高的矫顽力，以提高介质记录面密度的问题，采用控制变量法，研究了制膜工艺参数对TbCo薄膜矫顽力的影响，得到了TbCo薄膜获得高矫顽力的最佳制膜工艺条件。

After ultraviolet radiation disinfection of the effluent from WWTP,microorganisms can revivify due to the photoreactivation effects.

污水厂出水经紫外线消毒后在排放过程中会出现微生物的复活现象，为此考察了采用UV—氯和UV—过氧乙酸控制光复活的效果。

The light is controlled by a toggle switch combined with a dimming rheostat.

鉴于是控制由一个切换开关，配合调光变阻器。

As an important part of ASON control plane, a routing protocol is responsible for link state advertisement and routing calculation.

路由协议是自动交换光网络控制平面的重要组成部分，其负责链路状态宣告，并进行路由计算。

When the optical wavelengths adding/dropping and routing are realized in control plane, transport plane is lack of intelligent monitoring and adjusting to optical level signal. Because of dispersion, power unequalization and somthing else, the transmission quality of ASON can not be guaranteed.

在控制层实现光路的拆分、上下和路由时，传送平面缺少对光信号智能的监控和调节，由于色散、功率不均衡和信号的损伤，ASON的传送质量和业务的生存性就无法得到保障。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
