In this model, the skeletal storage coefficient was used for coupling, different storage coefficient were used for the calculation of storage change of aquifer and interbeds, the elastic and inelastic skeletal coefficients were used to account for the elastic and inelastic deformation, a one-dimensional diffusion equation was used for describing the delayed dissipation of unequilibrated heads within the interbeds, these make the model not only be able to simulate the elastic and inelastic deformation of soil, but also the delay phenomenon.

在该模型中，用夹层的骨架弹性储水系数进行地下水流模型和土体变形模型的耦合，用不同的弹性储水系数来计算夹层和含水层内的储水量变化，用夹层的骨架弹性储水系数和非弹性储水系数来体现夹层的弹性和非弹性变形，用扩散方程来描述滞后夹层内的水头分布，从而使模型能够很好地体现夹层的弹性和非弹性压缩，并能同时考虑夹层变形的滞后现象。

The method made lead and lag errors boil down to GPS errors, which could be emendated by map data on the basis of the observability of GPS errors along the vertical direction. A general Kalman filtering was constructed to process the information of corrected GPS and DRS later, Which decreased lead and lag errors in the integrated navigation system.

该方法是将超前滞后误差归结力为GPS误差，先利用GPS沿道路垂直方向上误差的可现测性进行GPS误差校正，再得校正的GPS信息与DRS信息进行卡尔曼滤波，从而喊少组合导航系统超前滞后误差。

As to the mate lag problems in loom beat up mechanism,comparing traditional four bar linkages with quick return four bar linkages beat up mechanism,the latter can solve the lag problems effectively.A CAD method of designing the quickreturn four bar linkages beat up mechanism is pointed out,and the design mathematics model and the kinematic analysis model are also presented.

针对现有织机打纬机构和开口机构在运动配合上存在的滞后问题，比较了传统的四连杆打纬和具有急回特性的四连杆打纬机构，基于后者能有效地改善配合上的滞后问题，提出了精确设计具有急回特性的四连杆打纬机构的CAD方法，给出了设计的数学模型、机构运动分析的数学模型。

Then the coupling degree has been analyzed about 31 regions (not including Hongkong, Macao and Taiwan) in China during the year of 2005. The result indicates that all the couping degrees in different provinces are rather higher, but the coordination degrees differ greatly and most of the coordination degrees belong to two types: medorate ang high coordination; from the point of the relation of ecological-environment to economy development most of the provinces have not reach the condition of harmonious reaction due to either sluggish ecological-environment or economy.

并对中国2005年31省区（不包括香港、澳门和台湾）的农业生态环境与经济发展的耦合度进行分析，结果表明，各省区农业生态环境与经济系统的耦合度均处于较高水平，但协调度却差异显著，且以中度协调与高度协调为主；从环境与经济关系看，绝大多数省区处于不同程度的环境滞后型或经济滞后型，农业生态环境系统与经济系统之间还远没有达到良性共振的状态。

The results show that, for the elasto-plastic contact of tip-substrate approach and separation process, the material plastic yielding in the atomic level is still governed by the von Mises criterion. For the adhesion of flat-ended wedges, continuum mechanics can be still applied down to a few lattice constants within the contact region, and give reasonable results, apart from the discrepancies near the contact edges. Moreover, adhesion hysteresis occurs during unloading due to the atomic steps, where the unloading curve does not coincide with the loading one. This in turn supports the presumption proposed by Pollock for the adhesion of stepped spheres.

本文首先对针尖—基体模型的弹塑性接触机理进行了深入研究，指出在原子水平上材料的塑性屈服仍由Von Mises准则控制；对平底锥冲头粘着接触的模拟表明，除了在接触区边缘附近有一定差别外，接触力学方法在接触区内几个晶格常数范围内仍能给出令人满意的结果；由于原子台阶效应，加载与卸载曲线不重合，出现粘着滞后，证实了Pollock关于具有纳米阶梯结构的球体粘着滞后现象的推测。

The main conclusions and outcomes are as follows:(1) From the coupling mechanism of economy and environment, the author appraises the degree of sustainable development in Jinlin province. The results show that the development orientation of Changchun is prone to economic development, for Jilin it is environmental development and for Liaoyuan it is harmoniums development at low level. By quantitative analysis, the author studies the status of sustainable utilization of water resources in this region from three aspects: water supply, drainage and water quality, and the results show that utilization of water resources in each of nine areas that belongs to Jilin province is at low level.

研究成果：（1）从经济发展与环境保护的角度对吉林省九个地区的可持续发展程度进行了度量，指出长春地区和吉林地区分属于高级发展类的强环境和强经济滞后模式，辽源地区属于低级发展类的协调模式，其它地区属于低级发展类的环境和经济滞后模式；从供水、排水、水质三个方面对水资源可持续利用进行了分析，指出吉林省各地区基本属于低层次和中层次的水资源利用，都没有达到水资源的可持续利用。

Hysteresis coefficient decreased both with increasing Al and Mn and decreasing Y at a given temperature and with increasing temperature at a given sample.

在相同的温度下，滞后系数随着Al、Mn浓度的增加而减小，随着Y浓度的增加而增加；对于同一组分合金，滞后系数随着温度的升高而增加。
