不平衡力

When N is equal to 1, the repulsion is the same with balanced force, distance is kept, and force is not displayed, is called to be pressure.

N=1 的时候，斥力相等，力平衡，保持距离，不显示力，叫压力，因为每点都均衡，但不是没有力，而力是双方立方力的总和。

It is effective to study the effect to the vibration of antiaircraft gun, by gun vehicle moving and bump、barbette traversing and cradle pitching、gun house recoil、Bourdon force、the mass center diviation and inertial imbalance of inbore projectiles, etc.

The results show that the peak tension in the conductor of upper crossarm at suspension point exceeds the design value. Insulator rupture has no effect on tower component of upper crossarm, but it has significant influence on insulator tension of upper crossarm. The lower limit of longitudinal unbalanced tension of two and more than two bundle conductor is relatively small. Insulator rupture should be taken into account in the design for overhead transmission lines.

分析结果表明，上横担一组绝缘子破坏失效后，破坏档未破坏端导线的张力超过了技术规程中的设计值；导线的跌落对破坏档未破坏端的上横担绝缘子受力有较大的影响，而对上横担铁塔杆件没有明显的影响；考虑杆塔断线荷载时，应增大两分裂以上导线纵向不平衡张力的下限值；在架空送电线路的设计中应该考虑绝缘子断裂的荷载工况。

The gravitational force on a mass in the meter is balanced by a spring arrangement, and a third force is provided which acts when the system is not in equilibrium.

重力仪本身质量引起的重力可通过弹簧布罩来平衡，且当系统处于不平衡状态时，系统提供的第三种力将会起作用。

轴承系统的不平衡量，给出了一种适合参数识别的非线性油膜力表达式，并引入遗传算法来识别非线性油膜力的动力系数和不平衡的大小和位置。

Work on the valve under the conditions of the above-mentioned unbalanced force, the choice of the method to change the direction of its role, is usually closed to flow into flow-based open-type, in general, the valve can easily solve the stability problem.

对阀工作在上述不平衡力条件下时，选用改变其作用方向的方法，通常是把流闭型改为流开型，一般来说都能方便地解决阀的稳定性问题。

Reverse angle valve is intended to improve Safety valves the use of unbalanced force and reduce the wear on the spool, but also conducive to high-viscosity, easy to medium coke and flow with suspended particles, to avoid coking and blocking.

角型调节阀反向使用的目的是为了改善不平衡力和减少对阀芯的磨损，同时也有利于高粘度、易结焦和含悬浮颗粒物介质的流动，避免结焦和堵塞。

Results are as following:The causes of grassland desertification of Hulunbeir are the outcome of interaction of nature and the human beings. Among these reasons, the loose soil texture, which was formed in the fluviolacustrine sediment during Quaternary, establish the physical ground, and the drought and wind is the natural force of grassland desertification. And then over-cutting forest, over-grazing grassland, imbalance of resource utilization and estrepement reduce the coverage of vegetation, therefore provide necessary conditions for the grassland desertification.

其中，形成于第四纪河湖相沉积沙的疏松土壤母质，为日后土壤风蚀奠定了深厚的物质基础；干旱多风的气候条件构成了草地风蚀沙化的自然营运力；而人为过度砍伐沙地林木资源、沙质草地长期超载放牧、资源利用不平衡以及乱垦、滥挖等不合理经济行为，又降低了沙化草地植被覆盖度，为草地风蚀沙化提供了必要条件。
