反斜度

In the design,the optimum radius of the rear convex mirror was presented which could efficiently compensate the effect of thermal lens,and the resonator would become a equivalent stable resonant operation dynamically. A slope efficiency of 13% and beam divergence of 1.3 mrad were achieved.

选择的凸面全反镜的最佳曲率半径有效地补偿了增益介质热透镜效应，激光器实现了动态稳腔运转，激光脉冲能量输出斜度效率大于13%，光束发散角优于1.3 mrad。

In this paper, the 3D finite element method (3D-FEM) is employed to calculate the responses of the dual-laterolog in the high angle deviated wells. Moreover, under the consideration of the impracticability of the strict 3D inversion of the electrical logging, one method named the fast deconvolution, is given to correct the electrical logs which is calibrated by the forward method, 3D-FEM.

在考虑常规双侧向测井和正演数值模拟计算的基础上，利用三维有限元素法（3D-FEM）进行大斜度井中双侧向测井响应的数值模拟求解，并以不同倾角为条件验证了方法的有效性；进一步针对目前严格的电测井三维反演处理的不现实性，应用严格正演刻度下的快速反褶积处理方法进行定向井的电测井曲线校正。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
