Once more, applys three-dimensional CAD software Pro/Engineer establishing the geometry models of all kinds of parts in the crank link mechanism, then useing the Pro/E software assembling function assembles the components of crank link into the piston module, the connecting rod module and the crank module, then using Pro/E software mechanism analysis module (Pro/Mechanism), establishes the multi-rigid dynamics model of the crank link, and carries on the kinematics analysis and the dynamics analysis simulation, and it studies the piston and the connecting rod movement rule as well as crank link motion gear movement envelopment. The analysis of simulation results shows that those simulation results are meet to true working state of engine.

再次，应用三维CAD软件：Pro/Engineer建立了曲柄连杆机构各零部件的几何模型，在此工作的基础上，利用Pro/E软件的装配功能，将曲柄连杆机构的各组成零件装配成活塞组件、连杆组件和曲轴组件，然后利用Pro/E软件的机构分析模块(Pro/Mechanism)，建立曲柄连杆机构的多刚体动力学模型，进行运动学分析和动力学分析模拟，研究了在不考虑外力作用并使曲轴保持匀速转动的情况下，活塞和连杆的运动规律以及曲柄连杆机构的运动包络。

The results showed that in the four rehabilitated forests, the previous month's soil moisture content had stronger effects on the current month's soil moisture content in 0-40 cm and 20-40 cm layers, but had lesser effects on that in 0-10 cm layer. The soil moisture content in 20-40 cm layer was mainly affected by current month's precipitation, while that in 0-10 cm layer was mainly affected by current month's evaporation. The correlation coefficient between current month's precipitation and soil moisture content was the largest in pure Liquidambar formosana plantation, and the auto-interrelation coefficient of soil moisture content was larger in mixed forests than in pure L. formosana plantation.

结果表明：研究区各重建森林前一个月的土壤含水量对当月整个土壤剖面(0~40 cm)平均土壤含水量和当月20~40 cm土层土壤含水量具有较强影响，对当月0~10 cm土层土壤含水量的影响较小；研究区各重建森林20~40 cm土层土壤含水量主要受当月降水量的影响，0~10 cm土层土壤含水量主要受当月蒸发量的影响；在4种森林重建模式中，枫香纯林当月降水量与当月土壤含水量的相关系数最大，混交林模式土壤含水量的自相关系数大于纯林模式。

Save city country labor to be in as economic development each littoral of each industry distributing produced apparent change.

Videlicet, this sequence represents the accountability of the 11 features in distinguishing insects on the level of species. According to the above results, some features varies not remarkably on all levels, such as Lobation, Shape-Parameter etc. This shows that such kind of features are nearly same in all species of insects, and can represent the feature suitable to distinguish all insects from other classes of animals. On the other hand, they are not suitable as distinguishable features of levels which lower than insect Class.

从结果可以看出，有些特征在各个分类阶元上差异均不是很显著，如叶状性、形状参数，说明此类特征在昆虫中具有较强的共性，可以代表整体昆虫的特征，而不适合于作昆虫纲下阶元的分类特征；有些特征在各分类阶元下的差异始终比较显著，如周长、面积等，说明这些特征适合在各分类阶元上作为昆虫的分类特征。

It means that each point cloud defined its own local coordinate system should be transformed into a common coordinate system, which is usually the ground coordinate system.

然而因各测站的点云资料均属於不同的局部坐标系统，必须透过转换将各站点云整合至统一的坐标系统中。

Because the data set of each scan is defined in a local coordinate system, data sets of multi-station must be merged into a unified coordinate system.

然而各扫瞄站点云云资料所参考的座标并不相同，因此必须先将各扫瞄站点云资料进行结合，才可进行后续的应用。
