查询词典 propagation

The properties of blast loading are that it is highly impulsive, exhibiting high-pressures but lasting for a very short duration. The propagation process of shock wave produced in steel-concrete composite beams subjected to blast loading is very short. And there is only small deformation for the beam during the time of the propagation process of wave.

由于爆炸荷载作用时间短、超压峰值大等特点，当爆炸荷载作用于钢－混凝土组合梁上时，将在梁内产生冲击波，冲击波在钢－混凝土组合梁内的传播过程极短，并且在冲击波的传播过程中梁的变形很小，因此，可将冲击波在梁内的传播过程进行独立分析。

Crack sliding induced microcrack surface normal dilation and normal dilation induced microcrack further self-similar propagation are considered, the ineracting of sliding and propagation is clarified. The fourth-order tangent homogeneous stiffness tensor of shear microcrack is deduced, and at last the constitutive model of low porosity is expressed in increment formulation though unit sphere surface integral.

3在评述当前常用的微裂纹滑移准则的基础上，提出了本文的滑移准则，考虑了微裂纹滑移引起的裂纹面法向膨胀，以及由法向膨胀引起的微裂纹进一步扩展，阐明了滑移-扩展相互影响的细观力学机制。

Through comparing with the local ERS\|2 satellite image this simulation also validates the effects of ocean topography on the propagation of internal waves such as fission and isobaths\|parallelized propagation direction.

对比于实地星载SAR图像，仿真结果也验证了内波在传播过程中受地形变化影响而出现的传播方向平行于等深线、分裂等现象。

The study was done to understand the first protected wild and critically endangered aquatic fern in China-Isoetes sinensis and to provide more detailed proof about its artificial propagation and emigrate protection. The germination rate of megaspores were statisticed through aseptic culture of spores for rapid propagation in I.

为进一步了解中国一类保护的水生极危野生植物中华水韭以及在大量人工繁殖和迁地保护等方面提供更为详实的证据，运用无菌培养、快速繁殖的方法对中华水韭的大孢子萌发率作了统计，探讨了不同温度对其大孢子萌发的影响。

A comparison is made for the above phenomena with the linear theory of TIDs propagation and also with a nonlinear numerical simulation of the dynamic features of AGWs propagation in the atmosphere. All these results are in good agreement.

这一演化过程与电离层中TIDs的线性传播理论一致，文中开展了对这一现象的非线性数值模拟，模拟结果基本上也与上述观测现象相吻合。

Effect of reinforced stringers and rings wave propagation of the shell was analyzed and mechanism of vibration depression was discussed by wave propagation theory.

结果表明，采用当前的加筋方案对壳体结构的振动噪声控制、固体传声控制和动强度控制具有良好的效果。

The crack and stress-strain of Chinese White Poplar were studied by the box counting method. The results showed that the cracks were obvious fractal and that the value of dimension D was determined to be between 1.2～1.5 by studying the crack propagation in the two dimensions. By comparing the crack propagation over a period of time, we found that the value of D increased as the crack increased.

运用数盒子法对裂纹发育带在二维平面内的分布进行了分形特征研究，发现木材裂纹具有明显的分形规律，分形维数为1.2～1.5；通过比较不同时间段的裂纹发育情况，发现裂纹的分形维数随着裂纹的扩展呈增加的趋势。

In a wireless communication apparatus (100), a frame generating part (120) adds a header to a data portion to form a transport frame. A control part (190) acquires a variation index in a propagation path and decides the length of the data portion of the transport frame in accordance with the propagation path variation index.

在无线通信装置(100)中，帧生成单元(120)将报头附加到数据部分而生成发送帧，控制单元(190)获得传播路径的变动指标并根据该传播路径变动指标来决定发送帧的数据部分的长度。
