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.

建立了滑翔彈道模型，以射程為指標函數(shù)亚洲欧美日韩一级特黄在线，考慮終端速度、高度和彈道傾角約束，采用龐特里亞金極大值原理和共軛梯度法求出控制變量有約束的最優(yōu)滑翔彈道999精彩视频，簡要分析了滑翔增程機理。

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.

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.

如果你出現(xiàn)了一秒鐘的猶豫，那么Nero接近到下個抓取點的角度就會變得陡直向上亚洲无码视频专区，在他抓住之后国产在线日韩一区，就直接被彈到天花板上去撞釘子了。
