达到目的

The spectrum of fiber Bragg grating can be controlled by double exposure technique. The first exposure is used to control the resonant wavelength of fiber grating by directly irradiating the naked photosensitive fiber.

该方法只使用普通Bragg位相模板，采用两次曝光技术，通过控制光纤光栅的本地谐振波长和反射率，达到控制光纤光栅谱形的目的。

According to analyse the safe performance of double-barrelled middle-level pressure acetylene generator in the extrusion type to the dipeptide, and carry on the improvement of structure, the object of the safe usage was attained.

摘要对双挤压式中压乙炔发生器的安全性能做了分析，并进行结构改进，解决了使用中的安全隐患，达到安全使用的目的。

The gravure business card printing and membership card deposit produced very thick (intaglio business card printing and membership card making ink film thickness is 9-20 μm, lithography business card printing and membership card making ink film thickness is only about 4 μm), the oxidation of trabeculectomies impossible to achieve quick-drying purpose gravure printing ink most fast with high volatility of drying oil based ink.

而凹版制卡和会员卡制作的墨层又十分厚实（凹版制卡和会员卡制作墨膜厚度一般为9-20μm，平版制卡和会员卡制作墨膜厚度仅为4μm左右），单靠氧化结膜无法达到快干目的，所以凹印油墨大多数采用高挥发快干性油墨。

Conventional root canal materials do not have enough dentinal adhesion and can not achieve the ideal sealing properties. Our research team has developed the polyurethane root canal obturation system containing ZnO/TPU cone and dual cured urethane acrylate sealer.

中文摘要传统根管封填材主要以马胶锥体搭配各类传统封填剂，然而马胶锥体及各类传统封填剂之间黏著力不足，和牙本质之黏著亦不理想，因此无法达到根管密封的目的。

Such pure software used method of dual module hot spare system that can improve system reliability on the basis of reduce the use of hardware dual module hot spare mechanism of the complexity and development costs, also be able to shorten the development cycle to achieve the purpose.

这种采用纯软件方法实现的双机热备系统，可以在提高系统可靠性的基础上，降低采用硬件开发双机热备机制的复杂性和开发成本，同时也能够达到缩短开发周期的目的。

As a result, a simple control method can not improve the dynamic performance of speed servo system. Integrated the advantages of self-adaptive control, fuzzy control and PID control, an intelligent dual module NC servo controller, called self-adaptive fuzzy PID controller is designed according to the modular design principle.

在光干涉弹流油膜测量系统中，速度伺服系统的控制参数和结构参数是影响速度伺服系统性能的主要因素，且具有时变性和不确定性，采用单一的控制策略很难达到提高速度伺服系统的动态性能的目的。

On the basis of study on dynamic data exchange,the method to the problem of a large number of ray tracing was discussed. The DDE of Matlab and Zemax and optical control integrated analysis in opto-mechanical system were implemented.

在研究动态数据交换技术的基础上，探讨了大数目光线追迹问题的解决方案，实现了Matlab和Zemax的动态数据交换和光机系统的光控集成分析，达到了光机系统光机控制集成分析的目的。

Finally, we designed a two-stage controller to compensate the influence of dynamic and static friction, respectively.

最后分别针对动、静摩擦力的影响而加以设计控制器，以达到抑制挠性结构的振动，及结构中刚体部分精密定位的目的。

If so, it has probably worked, and the Americans may now ease off.

如果真是这样的话，它很可能达到了目的，美国人或许可以松口气了。

The ecdysis mechanism is very important for the growth of H.

棉铃虫的蜕皮对其生长有着重要意义，因此，通过了解并控制棉铃虫的蜕皮，可以达到杀虫的目的。

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。
