交替收缩

Its development is not sustainable and steadily as our expectation, but alternately up and down.

它并不是像人们所期望的那样，持续、稳定地向前发展，而是经常地处于扩张与收缩的反复交替中。

In the predicted process, the forward simplification is used to get the interface equation, meanwhile taking the voltage of the concentrated grid as control vector to solve the control step length; in the correction process, by means of forward simplification and back substitution the Newton linearization incremental equations of both concentrated computational grid and contracted nodes are solved alternately.

进行计算时，通过前向简化形成预估环节的接口方程，同时以浓缩网络的电压为控制电压向量求出控制步长；校正环节通过双向迭代方法交替实现对浓缩网络和收缩节点的牛顿法线性增量方程的求解。

Results: In fasted rats, before stress gastric motor activity became regular in resting and contractile states.

结果：正常大鼠禁食状态，胃运动呈规则的相对静止期、收缩期交替的变化。

The basic view of the model that the intense subduction of the Indian plate beneath tbe Eurasian plate would result in inhomogeneity of the fabric and deformation of the lithosphere and repeated alternations of normal transformation from collision to contraction to stretching and reverse transformation from stretching to contraction.

其基本观点是强调由于印度板块向欧亚板块的强烈俯冲造成岩石圈组构和变形的不均一性及岩石圈中存在的碰撞→收缩→伸展的正向转变和由伸展→收缩的逆向转变的反复交替。

Any of various moths of the family Geometridae, having caterpillars commonly known as measuring worms that move by looping the body in alternate contractions and expansions.

尺蠖蛾任何尺蠖蛾科的蛾，通常称为尺蠖，通过身体交替的收缩和伸展来伸屈前进

Vicissitudinary changes of temperature and humidity can easily induce shrinkage cracks,and sometimes these cracks reflect to surface of asphalt pavement.

但从多年的实际应用来看，这种水泥稳定碎石在温度或湿度交替变化时容易发生收缩裂缝和干缩裂缝，当沥青面层较薄时，这些裂缝会反射到面层，形成反射裂缝。

When the finger is slightly raised, it is possible to alternate contractions between the flexors and extensors, and the slightly raised fingers can receive any added throwing motion by the hand and arm that accelerates their speed by the vertical adjusting motions much more effectively than the motion of a finger touching the key.

当手指稍微举起，屈肌和伸肌有可能交替收缩而且稍微举起的手指可以接受任何附加的下投动作，因为手和手臂促进了它们的垂直调节运动，使手触键变得更加有效了。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
