您要查找的是不是:
- sight line velocity 视向速度
- Maximum continuous flow based on pipe line velocity of 20 ft. per second. 最大持续流量以管路流速每秒20英尺为计算基础。
- Maximum intermittent flow based on pipe line velocity of 25 ft. per second. 最大间歇流量以管路流速每秒25英尺为计算基础。
- In practice of course there will be a dynamic lag in the antenna following the sight line. 当然,实际上在天线跟踪视线的过程中是会有动态滞后的。
- Either too low a line velocity or too high a velocity can damage valve internals and shorten valve life. 如果怀疑系统可能有问题,则在选型和订购截流止回阀之前,应该与美国太平洋阀门公司一起重新审核管道系统。
- If the sight line does not rotate in space then no steering commands are necessary as a missile is on a collision course. 如果视线在空间不转动,那么导弹总是在遭遇航线上,这就无需操纵指令。
- Based on the theory, wave propagates through the tilted strata, the method of 3-D irregular line velocity analysis (on condition that the dip is steep) is put forward. 本文根据波在倾斜地层中的传播理论,提出在大倾角情况下的三维非规则测线速度分析方法。
- Aim and Methods Three methods are analysed and compared for measuring the lateral deflection of gun bore axis from firing plane and the deviation of the sight line from the barrel axis, according to the results measured in practice. 目的和方法 本文根据实际测量中遇到的问题 ;分析了 3种测量炮膛轴线偏离射面的偏离角及瞄准线偏移的方法 .
- The included angle of the tester level sight line and observing sight line is zero.The straight rail and driven test car can make the tester see the pattern rotating along anticlockwise or clockwise. 驱动测试车,使测试者在测试板前面不间断地进行往返运动,测试者会看到,测试板上的图案在圆周上沿圆心做逆时针或顺时针转动。
- As internal grinder,the line velocity will decelerate along with the cut down of the grinding wheel radius,that lead to reduce of precision and smooth finish and grinding efficiency. 在内圆磨削的过程中,线速度随着磨削砂轮半径的减小而不断减小,导致磨削的精度和光洁度降低,磨削效率低。
