以2004年2月至2005年2月在本院门诊就诊的部分近视患者，应用眼科a型超声生物测量仪，对82例（164只眼）患者的近视屈光程度和屈光各要素（眼轴长度、前房深度、晶体厚度、玻璃体腔长度）测量值进行分析。

Increasing the length may enhance the gain of low and high frequencies when external acoustic meatus is wider, but only low fiequecies when narrow.

结论当外耳道较为宽大时，增加声管的长度可以提高低频和高频的增益；当外耳道较为狭窄时，增加声管的长度仅能提高低频的增益。

Under financial support by the Guanzhong Irrigation Improvement Project loaned by WB,the choice for the shapes of the water measuring flumes in U-shape canals have been carried out,based on the choice research,the straight wall type water measuring flume in U-shape canal was proposed for the optimal shape.

对U形渠道量水槽进行了选型，在选型的基础上，提出以U形渠道直壁式量水槽作为本研究的优选体型，并对U形渠道直壁式量水槽的体型、喉道长度、喉道宽度、过渡段长度、水尺位置、设计方法进行了优化研究，所得结果已在工程实践中应用，取得了良好的经济效益和社会效益。

It is necessity to take an impact test for FOPS in laboratory in order to install falling object protective structures at engineering vehicle and check its dependability.

为了对工程车辆的落物保护装置进行可靠性试验提供理论依据，采用冲击动力学的塑性波两侧的动量平衡理论对工程车辆FOPS受冲击时落锤的动态响应进行了研究，建立了锤头变形的基本方程，绘制了方程相应曲线；建立了锤头在冲击过程中任一瞬时变形长度和非变形长度的数学模型，找到了工程应变和冲击速度之间的曲线对于塑性大变形的突变点及影响落锤变形的各个因素和控制变形的依据。

Results 371 bp DNA fragment was amplified from 24 different species. The sensitivity could be improved to 10-12 g. No signal was observed when human DNA,funguses and viruses were used as templates. 22 blood samples and 4 cerebrospinal fluid samples, being positive with culture, were positive by using PCR. The gramnegative and grampositive probes hybridized to clinic samples and different species, as predicted by Gram stain characteristics.

结果 对24株不同标准菌株进行PCR扩增，均出现371 bp长度的DNA片段，敏感性试验可检测出10-12 g的细菌DNA，与人类基因组DNA、真菌及病毒无交叉反应；22例血培养阳性标本及4例脑脊液培养阳性标本均扩增出371 bp长度DNA条带，反相杂交法区分革兰阳性/阴性细菌与培养结果相符。

Long power control filters as compared to those used in Intra-cell handover could result in a scenario where Intra-cell handovers are performed where instead power up-regulation is desired.

如果功率控制的滤波器长度比在小区内切换中应用的滤波器和长度长时，结果会引起小区内切换被执行而期望的功率上调节不被执行。

For example, you could take the barometer out in a sunny day and measure the height of the barometer, the length of its shadow, and the length of the shadow of the building, and by the use of a simple proportion, determine the height of the building.

例如，你可以在一个阳光灿烂的日子里，把气压表拿出去，量一量气压表的高度和它影子的长度，再楼的影子的长度，利用简单的比例原理就能测定楼的高度了。

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