前置

It is shown that, the impact of IPI due to the pre-filter is insignificant to noncoherent receiver, and there exist different optimal pre-filter passband widths for different channels and input SNRs.

结果表明，在信道模型CM1~CM4下，前置滤波器产生的多径分量干扰平均来说对其输出能量的影响很小，并且一般来说存在一个最佳的滤波器带宽值。

Them指前面提过的Nyaya and Vai esika,英文可解为 able and earnest efforts to solve the problems of knowledge and on the basis of reasoned argument.

原文理解有误，而chaque兄的理解中似乎忽略了and being的并列特征，全部认为是&的&化的前置定语（开个玩笑，余光中说&的的不休&是汉译中一大症结

A sort of image acquisition system of paper's number with CIS based on ARM and CPLD is introduced.A re-al-time approach is brought out to collecting high-speed image information and image pretreatment.This system is mainly designed of hardware,the collected CIS image signal is saved in the SDRAM(synchronous dynamic random access memory) through pretreatment of occulting output com-pensation,secondary filter,analog digital converter and binaryzation,getting ready for further image...

介绍了一种自行设计的基于 ARM 及 CPLD 技术，利用接触式图像传感器采集纸币号码的图像采集系统，提出了一种实时采集高速图像信息及图像预处理的方法；系统以硬件设计为主，采集到的 CIS 图像信号经过明暗输出补偿、二阶滤波、模数转换、二值化等前置调理，保存在同步动态内存中，供 ARM 作进一步图像处理；系统中 CIS 传感器的时序信号由 CPLD 设计，实验表明，采集到的二值化图像清晰；这项研究成果可以推广到证券、票据号码的录入系统以及其他相关领域的字符识别系统。

Its leakage current is lower than 5nA at room temperature. The quantum efficiency in the wavelength range of 400-500nm is about 83%. The junction capacity is about 110-120pF. The noise level of PIN+PreAmp system is lower than 527e at -25C. The PIN diodes have passed the long-term stability test. All the main performances of our PIN diodes meet the requirement of ALICE/PHOS,and some of them are even better.

本工作研制的PIN硅光电二极管的灵敏区面积为16x17mm2，常温漏电流小于5nA，紫光区量子效率约为83%，结电容为110-120pF，以及由PIN光电二极管与电荷灵敏前置放大器组成的读出系统的噪声水平在-25℃下小于527个等效噪声电荷，并经过了长期性能稳定性的考验。

It is shown that the prenominal and postnominal types of relative clauses experienced different pathway of grammaticalization.

我们的研究表明前置型关系从句与后置型关系从句经历了完全不同的语法化途径。

Previous studies on the grammaticalization of relative clause structures almost exclusively focus on the postnominal type because of the lack of authentic data on the development of the prenominal type.

以往对关系从句的语法化研究主要是集中在后置型关系从句上，原因在于对前置型关系从句的发展情况缺少真实的语料。

Pre-Qin prepositions often have postpositional usage, due to...

前置词多有后置词用法，这与它们来自动词、而当时还有句法性OV语序有关。

A new desulfurization apprach for pulverized coal combustion is introduced in this paper; pulverized coal is first burn in a precombustion furnace under oxygen deficient condition (about 30% air needed in boiler is provided for precombustion), in precombustion moust of sulfur in coal is decomposed and oxidized, and evolved, the sulfur evolved is trapped in a desulfurizing fluidized bed by calsuim, and then the char and gas are introduced to the boiler furnace for complete combustion.

本文提出了一种煤粉燃烧脱硫新方案，利用煤中硫优先氧化分解释出的原理，用少量的空气（大略为锅炉实际空气用量的30％），在一前置燃烧室中，使煤粉中硫的绝大部分被分解氧化，释放出来，释放出来的硫在脱硫流化床中被石灰脱硫剂脱除，未燃烧的炭粒与烟气再吹进锅炉膛中完全燃烧。

The optimal controller and prefilter are designed on the basis of LQ specifications.

根据最优跟随器的线性二次型性能指标得出最优调节器和前置滤波器，结合实际目标的机动性和系统的限制对滤波器进行必要的简化。

Using prefilter compensator decoupling method, open loop direct force control law is designed.

利用前置补偿解耦方法对直接升力开环控制律进行了研究。
