平衡压力

The result showed that,if only the necessary but insufficient condition,the equilibrium condition ,was adopted to deal with the infinite uncertain boundary condition,the solution to the stress was non-unique due to the fact that the boundary problem here was a mal posed mathematic problem.

通过两个典型的半无限体实例，对水平表面作用无限均布压力下弹性地基的应力和位移解答进行研究，结果表明：对边界条件不明确的无限边界仅采用解答的必要非充分条件——平衡条件来等效处理，其应力解答不是唯一的，因为此时该边值问题不是一个适定的数学问题。

HT5H〗摘〓要：〖HT5K〗实验室研究了山西阳泉无烟煤在30 ℃恒温下注入N2对吸附平衡煤样中CH4的竞争吸附解吸特性，结果表明混合压力高于225 MPa后，CH4吸附量开始下降。

The concentrations of naphthalene in CO2-rich phase for the ternary system CO2 +［bmim］［PF6］+ naphthalene were determined by a static method with online high-pressure ultraviolet detection, under the conditions of naphthalene molality in the liquid phase ranging from 0.0169 to 0.378 mol·kg-1, and temperature 313—333 K,pressure 8—20 MPa.

采用紫外光谱在线检测的静态相平衡方法，在温度313～333 K、压力8～20 MPa、萘的液相浓度0.0169～0.378 mol·kg-1的范围内，测定了CO2+［bmim］［PF6］+萘三元系中萘在富含CO2相的浓度。

In this paper, we put forward a new kind of mechanism based on the analysis of the movement regularity of traditional horizontal reciprocating compressor which combined both magnetic suspension technique and linear driving technique. It takes advantage of the magnetic field force acted on the plunger, which will generates moment of couple to balance the corresponding moment ...

分析了传统卧式往复压缩机活塞连杆运动的规律，设计了一种集磁悬浮和线性驱动技术为一体的往复磁悬浮式压缩机机构，该机构利用作用于活塞连杆上的磁场力，使其力偶矩与连杆活塞的重力矩相平衡，使活塞对缸体的正压力趋向于零或等于零的理想状态，从而使摩擦副间的摩擦力达到最小。

Getting adequate amounts of protein is crucial to supporting your muscles and keeping your body in a positive nitrogen balance.

ASEAN, as the most successful organization in regional development and the biggest contributor to Southeast Asian countries' unity, wants to keep a balance between its real need and the USA's pressure since always, and finally writes "nonintervention in other countries' affairs" and "promotion of democracy and human rights" into the important milestone file-ASEAN Charter.

而东盟作为该地区发展最为成功、对团结东南亚国家贡献最大的组织，一直以来都在其现实需要与美国压力之间进行平衡，最终将不干涉内政和推进民主人权都写进了作为其重要里程牌的文件《东盟宪章》之中。

Producing of onset of nucleate boiling with subcooled boiling is early at same condition.

研究结果表明：自然循环欠热沸腾起始点的热力学平衡干度对加热量、进口温度、系统压力有着更大的敏感特性，在同等条件下，更早发生欠热沸腾现象。

The Failure model of slopes can be classified into 2 kinds, toppling model and sliding model. The force distribution of each model is analyzed in oblique coordinate system, and the equation to calculate the forces are derived. Many external forces, such as earthquake force, water pressure, bursting force, bolting force and etc., can be easily considered in these equations.

分析了倾倒模式和滑动模式两种岩质边坡的破坏型式，对其受力情况进行了分析，并利用刚体平衡理论，给出了在斜角坐标系下推力计算方程，该方程可以方便地考虑任意方向的地震力作用，还可以考虑水压力、锚固力、建筑物外荷载和其它人工作用力。
