研究了A，Sc(根据试验由有效截面积S的定义算出)，Sa及 Sv随阀开度x变化而变的规律，通过对比探讨了求解以上各种有效截面积方法的可靠性及相互关系等。

It researches the regularity of A (geometrical cross section area of valve), Sc (obtained by the definition of effective cross section area of valve), Sa and Sv (obtained by sonic velocity air exhaust method) to the change of the opening of valve, x. By contrastive method this thesis discusses the reliability and correlation of all methods above for solving effective cross section area of valve.

研究了 A， Sc （根据试验由有效截面积 S 的定义算出）， Sa及 Sv随阀开度 x 变化而变的规律，通过对比探讨了求解以上各种有效截面积方法的可靠性及相互关系等。

The fundamental problem is that our financial markets there is no effective market pricing mechanism, pricing of financial assets can not be effectively and where to effective interest rate?

最根本的问题是，我们的金融市场也没有有效的市场定价机制，定价的金融资产不能有效地和在哪里实际利率？

Unfortunately, most current research only simply assumed the market was efficient and made an efficient market be their starting point of research, but little exploration has been made to the essence of EMH.

但是目前可见的众多文献也只是简单地假设市场是有效的并在此假设上展开研究，却很少深究有效市场假说的本质含义。

In this paper we will use the concept of "mutual opposite form" to simultaneously recode two scalars stating at most significant bit to least significant bit, i.e. left-to-right recoding. We propose a new representation with low joint Hamming weight to reduce the number of elliptic curve point additions to achieve decreasing the operation cost.

本文将透过符号交替表示式，针对两纯量从最高有效位元(most significant bit， MSB)编码至最低有效位元(least significant bit， LSB)以同步的方式重新编码，新的表示式具有低结合汉明权重特性，可以减少椭圆曲线点加法运算次数，达到降低运算成本的目的。

EMA was the most effective antibody for differentiating chordoid meningioma from skeletal myxoid chondrosarcoma, low-grade chondrosarcoma, and enchondroma, whereas D2-40 was the most effective antibody for differentiating chordoid meningioma from extraskeletal myxoid chondrosarcoma and chordoma.

EMA是鉴别脊索样脑膜瘤和骨的黏液样软骨肉瘤、低级别软骨肉瘤、内生性软骨瘤最有效的抗体，而D2-40则是鉴别脊索样脑膜瘤和骨外黏液样软骨肉瘤、脊索瘤最有效的抗体。

Responsible for effective management of the interface and procurement work of EPC contractors.

对界面进行有效管理，对EP承包商的采购工作进行有效管理。

My Office is located in Zhejiang Province Tianmushan University, has rich forest resources, particularly resources are particularly rich pecan, pecan is a kind of epicarp environmental protection, low-cost coverage of a new type of garden materials, and its contains a biochemical factor that can effective in the soil to kill pests; and can increase the green color, rich green texture, landscaping, green landscape and green land; to prevent dust and soil erosion, improve air quality, so that a more pleasant environment; reduce transpiration, especially in summer, be conducive to maintaining soil moisture, prevent soil knot board, to maintain temperature, saving water, at the same time to effectively control weeds.

我处位于浙江省的天目山系，有丰富的森林资源，特别是山核桃资源尤为丰富，山核桃的外果皮是一种环保、价廉的新型园林覆盖资材，其含有一种生物化学因子，能有效的杀死土壤中的害虫；并且能增加绿地色彩，丰富绿地质感，美化、绿化园林绿地；防止扬尘和水土流失，提高空气质量，使环境更优美；减少蒸腾，特别是夏天，有利于保持土壤水份，防止土壤结板，保持温度，节约水源，同时能有效的控制杂草生长。

Ensuring the femoral epicondyle axes by the preoperative CT scan is an effective way to determine the femoral prothesis rotational angle.

术前CT扫描确定股骨远端后髁角可以有效提高TKA手术股骨假体旋转力线，方法简单、有效、重复性良好。

The traditional method is that sampling 20 equidistance discrete voltages to calculate the virtual value. To gain the virtual value, we firstly average their square values, and then extract it.

传统的计算有效值的方法是利用一个周期内等距离散的20个采样点的瞬时值进行求解，通过计算它们的均方根值来得到有效值。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
