周期带

Lower temperature will delay the stage of sensitive to photoperoid and thus enhance the percentage of diapause.

低温可以延长棉褐带卷叶蛾对光周期敏感的生育期，从而提高其滞育率。

The results of infrared dichroism indicate that molecules within mat-crystal structure are highly oriented in the shearing direction i.

以光栅效应计算了PPTA草席晶结构的长周期数据值及条带的取向状况，得到了较好的结果。

Note also that so far our jet engine is still working discretely, i.e. it is still operating on the SSBB cycle as used in a car engine.

还要注意的是，迄今，我们仍是喷气发动机工作不连续，也就是说，它仍然在黑带周期运行在汽车发动机使用。

The spread of the periodic wave, the advantage and disadvantage of the solid dynamic theory, the orderly system and the disorderly system physics; It also discuss the classification of the phase transformation and the division between the quantum method and the classical method in the condensed matter physics; and also point out the major developing trend of the present condensed matter physics.

对周期波的传播、固体能带理论的优缺点以及有序体系和无序体系的物理学；相变分类、凝聚态物理中量子方法与经典方法的界定进行了讨论，并指出了凝聚态物理发展的主要方向。

This is a toroid-shaped energy band that our solar system passes through twice in a 26, 000 year cycle.

The stress intensity factors and the size of saturation strips were derived analytically and their dependencies on the ratio of the periodicity to half-length of the crack h/l were analyzed in detail.

对应力强度因子和饱和条带尺寸进行了理论推导，详细分析了它们与周期长和半裂纹长的比值h/l之间的关系。

Holy Thursday could not but be a day of liturgical reunion since, in the cycle of movable feasts, it brings around the anniversary of the institution of the Liturgy.

圣周四，怎能不那麼一天的礼仪团聚，因为在周期的动产宴，它带给周围周年，该机构的礼拜仪式。

This thesis carries on research to a class of nonlinear Schrodinger Equation with wave operator of initial value periodic problem.

本文针对一维带波动算子的Schrodinger方程周期初值问题进行数值研究，对上述方程首先构造了守恒的半离散格式，然后将p次Hermite插值方法与有限差分方法相结合构造了差分正交样条配置格式，并证明这两个格式均为稳定和收敛的格式。

Because the magnetoelectricity characteristic of TA is not linear, huge short-circuit current or large nonperiodic current may make the TA enter the saturated state, which cause the exportation current of the TA very small, making the busbar differential current very large.

母线区外故障时，由于带铁心TA 激磁电感的非线性特性，强大的短路电流及较大的非周期分量都可能使TA 进入深度饱和状态，此时TA 的励磁阻抗将变得很小，一次电流大部分流入励磁支路，导致TA 输出电流很小，使得母线保护差动电流很大，如果不采取一定的措施，极易发生误动。

In Part 3 we study the mutualism system with several delays Sufficient conditions are obtained for the existence of positive periodic solutions of the system by using the theory of Mawhin coincidence degree .

第三部分考虑了两种群带多时滞的互惠系统我们利用Mawhin重合度理论，得到了系统正周期解的存在性的充分条件，推广了文[28，29]的结果，并且删去[30]的某些条件。

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.
