The simplest approach is to change the configuration of the ground equipment, such as mobile link beam to change the ground and pump stroke length; followed by replacing the motor pulley to control the number of red pumps.

最简单的做法是改变地面设备的配置，如移动游梁拉杆来改变地面和泵的冲程长度；其次是换掉马达皮带轮来控制泵的冲数。

In this paper, the limit load of buried pipe, that is used in Nanjing city nature gas using engineering, was studied by finite element analysis under various groundsill character, pedestal angle and ground pressure, and the risk assessment for this piping was performed. The limit load of buried pipe was measured by experiments. The research contents and results were as follows:(1) With FEA method, the effects of various groundsill character, pedestal angle and ground pressure on the limit load of buried pipe were studied.

本文主要针对南京市城市天然气利用工程的埋地管道，研究其在不同地基性质、支座包角和地面载荷情况下的极限载荷，并进行了试验研究，同时进行了风险评价，主要研究内容与结论如下：(1)通过有限元计算分析，研究了不同地基性质、支座包角和地面载荷对埋地管道极限载荷的影响。

Based on the data of 54 cases of local hailstone fall in central Gansu Province during the period from May to August of 2004-2006, the correlations between the VILmax or VILDmax and the geographical location of the regions with the maximal hailstone fall or the maximal diameter of hailstone cell on the ground as well as the Rmax discrimination are contrastively analyzed.

结果表明：①从总体上看，单体VILmax和VILDmax与地面最大降雹区的位置基本保持一致，且Rmax越大，一致性越好，但VILDmax与地面最大降雹区的位置比VILmax更接近。

Since the convective cloud system is tilted, and the viewing angle is oblique, the area displacement between ice hydrometeor and the surface rainfall rate makes the relation between Tb and surface rainfall rate is relatively small.

但亮温和地面降水强度之间的相关性较弱，这是由于该对流系统为倾斜的，冰相粒子和地面降水强度之间存在着位置上的不一致，并且观测角为倾斜的。

The problems were designed not only to get them a working knowledge of the mechanics of combat but to teach the most basic thing an infantryman has to know: how to love the ground, how to use it to advantage, haw the terrain dictates tactics, above all how to live on it and in it for days at a time without impairment of physical efficiency.

所设计的问题不仅给他们一些战斗机制运作方面的知识，而且教会他们步兵必须了解的基本知识：如何判读地形，如何利用有利地形，如何根据地形采取不同战术，尤其是如何在地面生存，在不影响体能的情况下一次在地面生存好几天。

Aiming at characteristics of land subsidence in Harbin City , based on investigation of settlement traces, the author used the layerwise summation method from the Rock Soil Engineering Reconnaissance Specification to calculate settling volumes of two infundibulum center regions, where are the Heavy Machinery Plant and Jiancaoling Town.

针对哈尔滨市区地面沉降特点，根据地面沉降痕迹调查，利用岩土工程勘察规范中的"分层总和"法，分别对两个漏斗中心重型机器厂和菅草岭的沉降量进行计算。

The pipeline structure of control signal transmission system is complex, and its initial value and boundary condition are also complicated.

在总结并评价了地面与井下通信系统的信号传输方式基础上，提出了地面信号下传系统的设计原则和设计方案。

The development and research progress of ground deformation induced by pipe jacking construction was reviewed in the paper.

对顶管施工引起的地面变形计算方法的发展概况及研究进展进行了分析，把地面变形计算方法归纳为现场监测方法、数值计算方法、理论方法和实例数据分析法，并进行了比较，以更好地指导工程施工。

The Lace-up group's center of pressure displacement quantity is bigger than other two groups,therefore its balance ability is also bad, therefore suggested the athlete when wearing ankle braces sports should inquire specialized doctor and the protection suggestion avoids injury.

人体在穿戴不同踝部护具执行单脚著地后迅速推蹬动作时， Lace-up和Air stirrup这两种护具在著地期间确实具有限制关节活动度的效果，但也因踝关节跖屈能力的下降造成人体著地时缓冲地面冲击力能力下降的现象，造成本研究结果在地面反作用力垂直分力Lace-up和Air stirrup组都较赤足组来的较大，著地时脚的负荷率Lace-up组和Air stirrup组都较赤足组来的较大，且Lace-up组在著地期压力中心偏移量也较其他两组大，故其平衡能力也有差异，故建议运动员在穿著踝部护具运动前应询问专业医师及防护员的建议以避免因此而受到伤害。
