Object identified by image mange technology, then, the changes of hue value is calculated by function F, finally the depth of object is gained by three step method. 5.

通过图像处理技术对操作目标识别分析，利用构建的F函数计算灰度值的变化情况，最后通过三步法得出操作对象深度信息。

According to kinematic method, the sub-models and total model about the mechanic energy loss of running are established. The mechanic loss during one step and the function of mechanic energy loss within the distance for 100m are discussed on the basis of simulation and experiment.

首先用运动学方法建立跑步运动机械能消耗分项计算模型和总机械能消耗模型，然后用仿真和实验的方法讨论了一个踏步的机械能消耗、并且模拟了100m运动员的全程机械能消耗过程。

This paper uses ADAMS/ View software to establish the model of bullet of smart cluster, uses the known drag index and STEP function to realize automatic inquiry of drag index.

通过ADAMS/View建立了灵巧子母弹子弹的实体模型。根据已知阻力系数，利用STEP函数实现了阻力系数的自动查询。
