突降

By applying the difference arithmetic to solve the differential vibration model of the single-degree-of-freedom,the acceleration responses of the vibrated bevel wheel was calculated.The bevel wheel contact fault was simulated by taking it as the impulsion loading in local point.By using techniques of wavelet de-noising and demodulated resonance,gear contact character information was picked up successfully.

从齿轮的单自由度振动模型出发，运用差分算法对模型进行求解，得到斜齿轮的振动加速度响应，将齿面接触型故障等效为在局部点突加一个冲击载荷，对齿轮齿面接触型故障进行了仿真，利用小波降噪和共振解调技术分别对仿真的染噪振动加速度信号进行处理，成功地提取了轮齿接触故障的信息。

The fibers which emanate from nucleus of lateral descending trigeminal tract directly project to the contralateral optic tectum which represents the center of integration of arrival and departure of impulses that control the general nervous activity and the behavior of the snake which do not have a differentiated hemispherical neocortex.

从三叉神经束外侧降核二级神经元发出的轴突投射到对侧视顶盖。由于蛇类不具有分化的半球新皮质，因此视顶盖为红外线感受系统的感觉与行为的整合中枢。

Immunohistochemically, the new crescent yellowish endings and fibers of trigeminal axon were SP and CGRP radioactive with granular, pearl and reticular delineations, mainly located at the 1rt and 2nd layers of lateral nucleus caudalis spinalis nervi trigemini.

免疫组化结果可见：P物质和降钙素基因相关肽的免疫阳性结构为轴突终末和纤维，呈现颗粒状、串珠状或交织成网状，主要集中分布在三叉神经脊束核尾侧亚核Ⅰ、Ⅱ层内，呈现新月形棕黄色显色。

Three expression vectors containing mutant gfp which were truncated from 3′ termine were constructed in the present paper.The mutation gfp with different length under the control by T 7 promoter were expressed in E. coli BL21 cells.

本文将突变型 gfp3′末端不同程度地截短，构建成表达载体，在大肠杆菌 BL 2 1中表达了不同长度的绿色荧光蛋白，当其生色基因中 65位 Ser点突变成 Thr，则 GFP的激发波由 396nm增至 4 70 nm，不用 UV激发，仅在自然光源下就可看到强烈的绿色荧光，发光强度增加 6倍，若从 3′端截短 12个氨基酸密码，对发光无影响，但截短 75个氨基酸密码，则激发波长降到 360 nm，发光强度减少 12倍。

The system performance simulation includes starting and breaking characteristics and steady-state characteristics, the results validate the rationality of the model. On above basis, the fault-operation performance of the system is simulated to demonstrate the phase redundancy speciality of multi-phase motor ;then the effect on performance of synchronous motor from damper winding is analyzed to indicate the its significance.

系统性能仿真主要包括系统起动性能，突变特性(突加负载，升频，降频等)，稳态运行性能仿真，仿真结果验证了所建立模型的合理性，在此基础上，对系统故障运行进行仿真，表明了系统相冗余特性；且分析了阻尼绕组在同步电机中的作用，说明了阻尼绕组的必要性与重要性。

It is also because of this that A Passage to India has its special charm in the whole British literary history. The researches to A Passage to India in the literature field vary in wide ranges.

文学界对《印度之行》的研究是从多方面、多视觉展开的，如人物的文化身份的分析认定，艺术手法上&突降法&的应用和对神秘主义的剖析等。

Rain, ice and snow are pelting the region as a strong nor'easter moves through.

由于一场强风暴过境，造成这些地区突降大雨，冰雹或大雪。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
