Changing meridional shape and blade angle can have large effects on the blade loading distribution 叶轮进口尺寸相同的情况下,子午形面和叶片角的变化对叶片负荷分布有较大影响。
You can select a new point using those widgets or by clicking in the fractal panel , which selects the nearest point 可以用这些小部件或在分形面板中单击选择新的点,选择的是最靠近的点。
The outline of objects can be measured by observing from two different positions , which is generally called 3 - d shape measurement 从两个不同的位置观测同一物体时,可测量出其三维轮廓,通常称为三维形面测量。
We have founded dps , what is more , we acquired principle of the effect of the cutting scheme and pressure on surface precision by using the dps 我们已经初步建立了数字摄影测量系统,并且利用它测量了裁剪方案和气压对形面精度的影响。
Two centrifugal compressor impellers with different meridional shape and blade angle were designed using computer - aided integrated design systems 摘要采用离心压气机计算机辅助集成设计系统,设计了两个不同子午形面和叶片角的离心压气机叶轮。
As a result , it is significant for suited design between structure and eletricity performance to research the surface accuracy of inflatable deployable antenna 因此研究充气展开天线的形面精度,对结构及其与电性能的匹配设计具有非常重要的意义。
Performance of inflatable antenna reflector hinges critically on the precision of the membrane surface . if the error is not in the range of limit , it will heavily decrease antenna gain and increase sidelobe level 形面精度是决定充气展开天线反射器性能的一个关键因素,如果误差不在允许范围内,那么它会严重降低天线的增益,增加旁瓣电平。
The experimental results from subjective assessment on four kinds of seat cushion indicate that the chair seat is an important factor affecting seating comfort , different chair seats are endowed with the corresponding seating comfort 4种曲面座垫的主观评价实验结果表明,座椅形面是影响乘坐舒适性的重要因素,不同形面特征的座椅具有不同的乘坐舒适性。
