It is evident that the 3 - dspatio - temporal sampling grid contains more information than any 2 - d still - frame sampling grid 显然，三维时空采样比任何一个二维静态帧采样栅格而言它包含更多的信息。
2.
The rigid shaft model and flexible shaft model of the drive train based on the spring - mass - damper system are used to analyze the dynamics of the drive train . a sample grid - connected 300kw hawt is simulated using the analysis method 在此基础上以并网型300kw水平轴风力机为分析对象，对其传动系统在紊流风场作用下的动力学性能进行了仿真计算并分析了计算结果。
