查询词典 occur to

When the chirped pulse with area smaller than propagates in the medium, splitting doesn't occur and the chirped pulse evolves gradually to an approximate normal Gaussian pulse (C=0), and this characteristic doesn't vary when the chirp coefficient; however, variation of the chirp coefficient will change amplitude and group velocity of the pulse.

面积小于的啁啾脉冲，在介质中传播时不发生分裂，且啁啾脉冲逐渐演化为一个近似的无啁啾(C=0)脉冲，这一特点不随啁啾系数的改变而改变；但啁啾系数的变化将改变脉冲的振幅和群速度。

In this case,if we are still based on the stock index returns in the previous period.then bigger bias may occur and we might make error judgement,therefore we should cogitate these factors when studying the return levels.

在这种情形下，如果仍然以前一时期的股指收益率数据拟合模型为依据，对现时期的收益率进行预测等统计推断，可能会产生很大的偏差甚至会造成错误的判断，因此我们在研究返回水平时应该慎重考虑这些因素。

In addition, we proposed a supposition that the optic coherence condition doesn't occur after the superposition of the different light distances to attain the depolarizing aim.

透过此假设，我们成功地用光偶合元件架构出新的解偏振器，其理论推导及实验结果，均在论文中呈现出来。

The gaseous impurities in the alloys were well controlled with the sum of C, N and O less than 500wppm. For the first time it was found the strong interaction between Cr-Ti-CON, which reduces the mobility of Ti and CON, enhancing high-temperature strength and the aging-hardening property, and keeping the cold-work induced hardening at higher temperature. Aging-hardening could increase the tensile strength of V-4Cr-4Ti by 30% and could be utilized at 00 C for better economical performane of a vanadium structure. Hydrogen release will occur for the alloys tensile loaded at room temperature, which will affect the safety of a vanadium structure due to the resulting dimensional instability. For hydrogen embrittlement, impact toughness and fracture toughness of the alloy showed higher sensitivity than the tensile test elongation,so the toughness should be used as a new standard for the assessment of the embrittlement. Vanadium alloys were easily oxidized in air.

合金的气体杂质含量得到有效控制，C、N、O总量低于500wppm；首次发现Cr-Ti-CON之间的强相互作用，它使Ti、CON的高温可移动性降低，提高合金的高温强度、增强时效强化特性、使冷加工强化保持到更高温度；时效强化可使V-4Cr-4Ti的强度提高30%，可在低温（00C）下应用，提高构件的经济性；室温下，钒合金在拉应力的作用下，存在着氢释放，带来部件使用中的尺寸不稳定性，影响构件安全；氢脆是钒合金聚变应用的一个关键问题，合金的冲击韧性和断裂韧性表现出比拉伸延伸率更强的氢脆敏感性，应作为评价合金氢脆行为的新标准。

Some of the largest paredes occur on Columbus Day, Veterans Day (November 11), independence Day

一些大型游行在哥伦布纪念日（10月的第二个星期一），退伍军人节（11月11日），独立日（7月4日），及劳动节（9月的第一个星期一）举行。

In other words, the results novelty broke the conclusion in the pervious reports that combustion synthesis can't occur once Fe content in Fe-Ti-C system is more than 60wt%, and gave more engineering meaning to combustion synthesis of iron-based composites.

而这正是本研究的创新点之一，即打破了前人研究所得出的"Fe-Ti-C体系中Fe含量超过60wt％就不能实现燃烧合成"的界限，从而使Fe-Ti-C体系燃烧合成制各铁基复合材料更具有工程意义。

It is distinguished from combustion by the fact that oxidation does not occur.
