弹出

Aimed at the problem of the salt bed wellbore creep and shrink under the drilling,based on the elasto-plastic mechanics theory and the head creep equation,the new formula of the control wellbore shrink rate was derived with in case of the plane strain and uniform in-situ stress,which was different from the old formula.

针对钻井过程中钻遇的盐层段井眼蠕变缩径问题，利用弹塑性力学理论，蠕变本构方程采用Heard蠕变方程，在平面应变和均匀地应力假设下，推导出控制井眼收缩的钻井液密度新公式，该公式与前人推导的公式不同。

Techpriests are invaluable as they can administer repairs during a conflict, risking their lives to reach a stricken machine, and braving the bolt shells and las blasts in their endeavour through its steely throat.

机械牧师会冒着生命危险穿过硝烟弥漫的战场，去修理瘫痪在阵地上的机械武器，并勇敢地面对从冰冷的枪膛中急速射出的爆弹强枪弹药和激光波，所以对于帝国防卫军而言，机械牧师称得上是无价之宝。

For many decades it offered yawnsome pontifications by senior officials who repeated conventional wisdoms. In the 1970s, and also more recently, it has shown marked signs of life.

该刊几十年来皆刊登资深官员重弹夙儒的八股之论，1970年代起，乃至近年，该刊已经显示出与时俱进的生命活力。

As reported, the celestial guidance of single-star scheme can correct initial localization, orientation errors and constant drifts of gyro in mobile launching ballistic missile, while we consider that the scheme can only compensate for partial constant gyro drift .

有参考文献认为，采用单星制导即可以估计和补偿初始定位误差、初始方位误差、陀螺常值漂移等误差源导致的弹载惯导系统定位误差，但我们认为，单星制导不能估计出全部的常值陀螺漂移。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
