expansive pressure meaning in Chinese
膨胀压力
Examples
- It can be used not only to change the fire precision of the base bleed projectile , but also to improve the effect of reduction drag and expansion range . the calculating model of the secondary expansive pressure of the burning gas is constructed by means of analysis of the experimental resuits , it has been confirmed that the new base bleed unit can be designed , with the secondary expansive principle of the burning gas pressure . the engineering project of a hybrid base - bleed - rocket high - level efficient extended - range projectile is designed , with the secondary expansive principle of the burning gas pressure , the feasibility and the true worth of its engineering applications is validated in theory
本文提出了底排燃气压力不随外部压力变化，既可改善底部弹射击精度又可提高减阻效果的二次扩张原理，建立了底排燃气二次扩张压力的计算模型，并通过采用二次扩张原理的新型底排装置与传统底排装置的对比试验，验证了新型底排装置结构实现的可行性；完成了基于底排燃气二次扩张高效增程原理的底排?火箭复合高效增程弹方案设计及其有关计算，从理论上验证了其工程应用的可行性和实际价值。 - In this model the anisotropic constitutive models of concrete are introduced according to its different behaviors under compressive stress and tensile stress , and it is considered that a certain amount of rust product is carried away from the rust layer around the reinforcement and deposited within the open cracks after the cover cracked , which will reduce the expansive pressures
由于混凝土拉压性能的不同，应用各向异性本构关系，并考虑保护层开裂以后，钢筋的锈蚀产物会有部分渗透到裂缝中，降低锈蚀产物对保护层的膨胀压力，对钢筋锈蚀膨胀应力进行了计算。
