查询词典 compression engine

It is widely concerned in fatigue of concrete structures. In this paper, concrete triaxial compression fatigue experiments and tension-compression fatigue experiments with constant confinements in two lateral directions have been carried out using a self-modified loading apparatus. Based on the analysis of the test data, the quantitative principles of concrete fatigue deformation and the calculation method of fatigue strength are determined.

混凝土结构的疲劳是一个广为关注的问题，本文针对这一问题结合国家自然科学基金项目——混凝土多轴变幅疲劳破坏准则(50078010)的研究，利用自制的试验加载装置完成了两向定侧压约束下混凝土三轴受压、三轴拉-压等幅和变幅疲劳试验，对试验结果进行了分析。

The results obtained from finite analyses indicate, under assured weld quality, the effect of ratio of axial compression stress to strength is relative better to moment-resistant bearing capacity of column joint, the ratio of axial compression stress to strength is bigger, the moment-resistant bearing capacity of column joint is bigger, earthquake resistant capacity is better

结果分析表明：在保证焊接质量的前提下，轴压比对节点柱的抗弯承载力影响较大，轴压比越大，抗弯承载力越大，节点的抗震性能越好。

At present, the dominating new standards used for HDTV video compression are H.264/AVC and AVS, both of them adopt block-based integer transform, quantisation and block-based motion compesation, which will be the source of blocking artifacts and will reduce the subjective video quality and compression performace.

In order to help for evaluating properties of soil in interaction more precisely, the paper applies elastic theory solution on different modulus in tension and compression for vertical load into semi-infinite elastic body. Through quoting Heaviside function, the solution of elasticity theory with different modulus in tension and compression is established founded on the solution of elasticity theory for the material incapable in tension and Mindlinsolution for equal modulus.

为使地基土在共同作用中的行为特征评价更为合理，本文应用了半空间问题竖向荷载下地基土的拉压模量不同弹性理论解，该理论解是通过引入Heaviside函数，利用不能承受拉应力材料的弹性理论解并结合拉压模量相等的经典Mindlin解而获得。

An engine cyclic variation model has been built by using the residual gas temperature for the n-th cycle as the input of the model, through constant pressure intake process, adiabatic compression process, constant volume combustion process, adiabatic expansion process, adiabatic blow down process and constant pressure exhaust process to approximate the thermodynamic processes in the cylinder, finally the residual gas temperature for the (n+1)-th cycle can be estimated.

基于循环间变动的排气温度建立了一个发动机循环变动模型。在这个模型中，第n个循环的排气温度作为模型的输入，通过定压进气过程、绝热压缩过程、定容燃烧过程、绝热膨胀过程、定容放热过程和定压排气过程来近似汽缸内的热力学过程，最后得出第n+1个循环的排气温度。
