地面压力

Due to we use high quality aluminous material which has high compressive rigidity and corrosion resistance, so it can be used for walls, floors, shower room and etc.

由于我们用的是高品质的铝材料，有着很强的抗压力和耐腐蚀性，所以它可以被用于墙面，地面，淋浴房，等等。

This paper will analyze the mechanical performance of the wheel and design a test-bed to test the performance of the lunar rover's wheel. Firstly, the mechanical characters of the soil are separated to press-sinkage character and shear character based on Bekker's theory, and common press-sinkage and shear models are introduced and the theory of Lankine passive earth pressure is also introduced. These basic theories are helpful to construct model.

根据Bekker半经验法的基本思想，将土壤的力学特性分解为水平方向的剪切特性和竖直方向的承压特性，阐述了地面力学中常见的土壤的承压、剪切等力学模型，并引入了朗肯被动土压力理论，为建立车轮在松软土壤中前进和转向的力学模型奠定了基础，同时进行了实验土壤的剪切实验，测量了土壤的内聚力和内摩擦角等参数。

The curtain for cutting off water in well point recharging system is an economic and suitable way, which has positive influence on reducing the sink of surrounding resulted from dropping water in foundation and has a wide prospect in its usage.

井点回灌系统截水帷幕是利用回灌井点，在基坑降水的同时对地层补水，由于回灌压力的作用形成截水帷幕，阻挡保护区内地下水的流失，使基坑周围一定范围内的地下水保持动态平衡；井点回灌系统截水帷幕是一种经济适用的截水帷幕施工方法，它对减少由基坑降水引起的周围地面沉降具有积极的工程意义和广泛的应用前景。

The acceleration of the ground surface, excess pore water pressure ratio at GL?

加速地面，超孔隙水压力的比例在GL的？

Summary: A kind of irrigator applying to arbors in city virescence belts was studied, which has a great capacity and has no effect on scenery because it was buried round the roots of trees. It also has a lot of characters such as the filtration of water resource is undemanding, the seepage of water completely depends on gravity, the working stress of transporting water is low and so on..

本文研究了一种应用于城市绿化带乔木的地下渗灌装置，它具有容量大，埋设于树木根区土壤中不影响地面景观，对水源过滤要求低，完全依靠重力渗灌，输水工作压力低等特点。

The results showed that middle aged women used greater force on contact and leaving phase;the muscle activity and balance control capability of middle aged women on the first metatarsus and heel area were better than those of elder women's.Middle aged women can generate more ankle movement while the other parts of the b...

结果显示：中年女性在行走时无论是在脚刚接触地面还是在离地时所用的力均大于老年女性；中年女性第一跖骨和足跟部位的肌肉活动和平衡能力控制优于老年女性；中年女性可以在身体其他部位运动的同时使踝关节产生更多的运动，并产生更大的水平力来确保压力中心处于支撑面范围内。

A large pneumatic tire may have very low ground-contact pressure, resulting in minimal disturbance to the surface and minimum rolling resistance.

一个大汽车轮胎可能有非常低的地面接触压力，导致在最低限度的干扰，表面上和最低的滚动阻力。

In the preliminary design, three scheme are drawn out for selection, they are:①pressure shaft with underground power house;②penstoek with ground power house;③pressure shaft with ground power house; and the first one is rec...

在初设审查中，经反复论证比较，选定了"压力井道—地面厂房"方案作为本工程的采用方案。实践证明，初设审查所选定的方案是正确的，达到了预期的目的。

The tail of the plane is sticking out of the ground, obviously it exploded upon impact, it had 5,800 pounds fuel on board and if you could expect what you would see with that kind of explosion.

飞机尾部划向地面，显然由于压力发生爆炸。机上装有5800磅的燃料，如果你愿意，你可以想象面对这样的爆炸你会看到什么样的情景。

Through two methods measuring cutoff thrust and pressure of com - bustion chamber when testing liquid propellant rocket engine on ground , cu - toff impulse as simulated altitude condition is obtained .

本文叙述在地面条件下试验液体火箭发动机时，通过测量发动机后效段推力与测量发动机燃烧室压力两种方法来求得模拟高空后效冲量，并对这两种方法作简单评论。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
