To research the effect of pin carding plate on removal of impurities from card slivers,impurities tests were carried out for the card slivers under different gauges,taker-in speeds and doffer speeds using pin carding plate, saw-tooth carding plate and taker-in grid under the card taker-in by USTER AFIS single fiber tester.

为研究梳针分梳板对去除生条中杂质的影响，用USTER AFIS单纤维测试仪对梳棉机刺辊下加装梳针分梳板、锯齿分梳板和采用小漏底在不同隔距、刺辊速度、道夫速度条件下所加工的生条进行杂质检测。

In the organic glass tower of 600mm in diameter, the pressure drop, leakage and mist carrying of the high efficient flow-guided sieve tray were measured in the experiment and we found that there was no flooding phenomenon when the resident time of liquid in the downcomer was less to 2. 5 second. It shows that the structure of the tray is reasonable and it can increase the column capacity greatly.

在自建的φ600mm有机玻璃塔内对高效导向筛板的各项流体力学性能进行有关实验研究，其中发现在高气速下当液体在降液管中的停留时间低至2.5秒时，仍没有观察到液泛现象，说明高效导向筛板可在不改动降液管的情况下大规模地提高塔设备的液相通量和生产能力。

There is a gradual decrease in effective filament diameters of different cross section fibers with the rise of taking-up rate or the decrease of pump flux.

研究发现，O-Y型和O-C-Y型喷丝板中各种孔的单孔流量比在3左右，适当调节工艺条件，可以得到O-Y型和O-C-Y型同板多形PCS纤维。

At one time, developing a new embranch subject -Binary Optics, it make use of diffraction theory,Computer Aided Design and VLSI ,sculpting the embossment of two or more steps on the surface of optical instruments , its photic characteristic including pure phase ,coexiting reappearance and high diffraction efficiency.

在光纤通信和光信息处理中具有重要的作用，可以完成站点与站点、系统与系统、板与板、芯片与芯片以及各逻辑处理单元之间的光信号连接、多项式求值、排序、快速傅立叶变换、矩阵变换等功能。

Although abroad do poineering work board only accept Si Na overcomes one branch in the market alone beautiful, but this cannot explain China is rolled out do poineering work board foreground is dim; Manage together, although Shanghai is deep,two city market prise evaporated 20%, can explain those think only short-term accrual congenial personage engorge its are deficient, and the investor that expands foreground to dedicated and long-term investment and enterprise, the market risk that this just must assume stopped.

虽然海外创业板市场中只有纳斯纳克一枝独秀，但这不能说明中国推出创业板前景暗淡；同理，尽管沪深两市市值蒸发了20%，只能说明那些想短期获利的投机人士大吃其亏，而对于专注长期投资和企业发展前景的投资者，这只是必须承担的市场风险罢了。

The parameters Euler's number and region area are chosen as characteristic values to built the fault module identification tree for the sake of auto-identification of several ordinary faults.

PCB光板缺陷检测中，根据PCB光板图像和缺陷的特点，选用了最大熵阈值分割算法对图像进行二值化处理，并以欧拉数和区域面积为特征值，建立缺陷模式识别树，实现常见几种缺陷的自动识别。

This paper used anhydrite associated with ferruginous mineral from Cheng Chao iron ore as primary raw material to develop successfully a new type of light wall material under the action of G N M J four compound excitation system and FX compound reinforcing fibre with suitable forming procedure.

本研究以武钢矿业公司程潮铁矿共生的硬石膏为主要原料，在广泛探索的基础上，筛选出G－N－M－J四元复合激发体系，有效地激发了硬石膏的活性，在FX复合纤维的增强作用下，采用合适的成型工艺条件，成功地研制出一种新型的轻质墙体材料—纸面硬石膏板，对试制样品的测试结果表明，各项性能达到或接近以半水石膏为主要原料的纸面石膏板的国家标准，为综合利用程潮铁矿的矿物资源开辟了新的途径，对硬石膏在新型建筑材料领域中的开发应用，更有着开拓性的意义。

A new bionics propulsion equipment—fishlike flexible tail fin propulsion equipment is brought forward,because there are some problems in present thrusters,such as big noise,low propulsion efficiency in shallow water and evident wake.

本文针对现有船用螺旋桨、泵喷等常规推进器存在噪音大、浅水中船舶推进效率不高以及尾迹明显等缺点，提出一种新型仿生推进装置—仿鱼尾柔性尾鳍推进装置，并据此展开了对单翼板柔性尾鳍和双翼板柔性尾鳍模型的计算和实验研究，本文工作属于鱼类生物流体力学、机械学、材料学和控制技术等多学科交叉的一个新兴研究领域。
