零时

Cantilever beam holding object is controlled through changing direction of voltage applied. When the voltage is zero, release the object.

改变加电压方向控制悬臂梁夹持物体，电压为零时释放物体。

Lastly, the paper also studies on a generalized discrete insurance risk model of two-type claims, the problems are resolved, such as the survival probability、ruin probability when the initial capital is zero and the ultimate ruin probability.

最后，对广义复合双险种负二项风险模型进行研究，得到了盈余过程的性质、初始准备金为零时的生存概率及破产概率的表达式。

Clean energy economy will lead to higher consumption per capita than harmful energy economy when CER value is high enough and the cumulative net capacity is zero. On the contrary, clean energy economy will lead to lower consumption per capita than harmful energy economy when CER value is not high enough, which means it is not able to counterweigh the cost of ethanol, or when ethanol production efficiency is low enough.

3当CER价值足够高而净资本累积为零时，洁净能源体系会较污染性能源经济体系造成较高之人均消费；反之若CER价值不够高，亦即不足以弥补燃料酒精生产成本时，或者燃料酒精生产效率足够低，则可能获得较低的长期人均消费水准。

When the count-down timer for cooling reaches 0 the entire electrofusion process is completed.

待冷却时间倒计数为零时，整个熔接过程结束，关机并拔下连接插头。

When the cooling time is counted down to 0, the entire electrofusion process is completed, turn off the machine an ...

待冷却时间倒计数为零时，整个熔接过程结束，关机并拔下连接插头。

The results shows that: as the fast ions numberα=0, ie., the ions number density reduces to the Boltzmann ion distribution, the solitary waves are all rarefactive, which are in good agreement with Ref. [81]. as the fast ions increases, the compressive waves can also exist in some special regions.

结果表明，当快离子数为零时(α=0)，即离子分布退化为玻耳兹曼分布时，该系统只允许稀疏形孤波存在，这与文献[81]的结论相一致；而随着快离子数的增加(α≠0)，在某些特定的区域，还会出现压缩形孤波。

Transmission of Gaussian light pulse in sinusoidally dispersion-compensated system is studied by numerically simulating the solution of non-linear Schroedinger equation.

从含非线性薛定谔方程出发，通过数值模拟，研究了高斯光脉冲在正弦型色散补偿系统的传输，得到结论：当系统的二阶色散的平均值为零时可得到高斯光脉冲的稳定传输。

When vaccinal ratio is greater than zero, the critical infection value becomes greater with the time increasing.

当接种比例大于零时，传染率需要跨越更大的传染临界值疾病才能流行，且随着时间的增大传染临界值也增大。

During the process of new travel agencies entering, every travel agency readjusts its geographical position based on equal area.

当进入利润为零时，市场到达容纳最大数量旅行社的临界点，达到均衡，所以无论旅行社如何调整选址，都是在等面积需求处定位。

In situ measurement of suction, which is absolute of the negative pore water pressure when pore air pressure is zero, is expensive and time-consuming.

现场直接测试吸力（气压为零时吸力是负孔隙水压的绝对值）成本高、精度有限。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
