查询词典 glide angle

Taking range as the performance function, considering end velocity, height and trajectory slope angle constraints, the optimal glide trajectory was solved by maximum principle of Pontryagin and conjugate-gradient method.

建立了滑翔弹道模型，以射程为指标函数，考虑终端速度、高度和弹道倾角约束，采用庞特里亚金极大值原理和共轭梯度法求出控制变量有约束的最优滑翔弹道，简要分析了滑翔增程机理。

In kick hitting, the moving forward velocity of bat is the highest when the ball was hit at the right moment, which the left elbow angle is almost 180 degrees and the right elbow angle is between 100-110 degrees. In the hitting process, the displacement of body in backward/forward direction and the resultant velocity with kick hitting are larger than those with glide hitting.

一、在击中球瞬间抬腿击球法左肘关节角度接近伸直与右肘关节角度介於1 00度110度时，球棒的前移速度最大；且在整个挥棒过程中前后方向身体重心位移、合速度明平均大於滑步击球法。

The puzzle is more difficult than it initially looks--quick reflexes are needed in order to glide from one snatch point to the next, as even a second's hesitation will steepen the angle of Nero's approach to the next point and send him crashing into the ceiling spikes.

如果你出现了一秒钟的犹豫，那么Nero接近到下个抓取点的角度就会变得陡直向上，在他抓住之后，就直接被弹到天花板上去撞钉子了。

A method was proposed for approaching the glide trajectories based on nsegment constant gliding angle.

提出用包含地球旋转效应的n个常滑翔角飞行段近似实际滑翔飞行轨迹的方法。

The approach to calculating the gliding angle and flight time of each segment was given.The procedure for approaching the whole glide trajectory was described.Two examples show that the differences in the gliding range and flight time between the approximate solution and the...

文中算例结果表明，该近似求解方法计算得到的滑翔航程和滑翔时间与实际值相差很小，航程误差率约为0.7%，时间误差率约为0.6%，因此该方法在近似小初始滑翔角的长航时远程纵向滑翔飞行时是有效的、可行的，尤其针对航程在地球半圈以上的滑翔飞行轨迹。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
