查询词典 propagate

Even though at a very low temperature (-196℃), the cleavage cracking dominates the fracture process, it can not propagate straight forward through entire ligament and shows the pop-in extension in macroscopic tests and the quasi-cleavage mode in microscopic feature. It is found that the strong resistance which hinders the crack propagation is provided by three barriers: original austenite grain boundaries, bainite colony boundaries and inter-layers between bainite laths.

在－196℃的极限温度下，准解理开裂控制了整个断裂过程，但它仍然不能扩展通过整个韧带，在宏观曲线上出现POP-IN的扩展特征，微观上表现为准解理特征和韧性撕裂特征断口交替出现；同时发现阻止裂纹扩展的阻力来源于三个方面：原奥氏体晶粒边界，贝氏体团边界以及贝氏体片。

The release of the footage is a stark contravention to the international law .the Taliban is exploiting the solder to propagate itself .we are delightful to see the solder unharmed , and we will try every possible means to sure his release in safty and security .we are using all resouse available to archieve this targe , and we are contacting the locals by every possible channels ,for instance we have leafleted a telephone number to the afghanistans so that any of them who knows the whereabouts of the captured solder can contact us .

播放这段视频明显地违备了国际法。这是塔利班在利用这名士兵来达到自己的宣传目的。看到这名士兵身体似乎无恙，我们感到很高兴，我们将尽一切可能使他毫发无损的、安全的获释。我们正在用可利用的一切资源来达到此目的，我们正在用可利用的一切手段与当地人取得联系。例如，我们用传单公布了一个电话号码，以方便那些可能会知道这名士兵被押地点的阿富汗人与我们取得联系。

The numerical results of stationary and transient Green'sfunction for high-velocity surface-head wave on some selected crystals are comparedThrough the above analyse,it is indicate that the first arrival wave mode is thelongitudinal-wave head-wave,and its propagate velocity is equal to the groupvelocity of the longitudinal bulk wave alone the surface.Furthermore,this modedoes not have the Δv/v effect,i.e.,its velocity is the same no matter the surface isfree or metalized.

通过对表面激发的瞬态和稳态Green理论分析和数值计算，表明在压电晶体表面上实际上看到的最高速的最先到达的波动模式是纵波头波，它具有沿表面纵波的群速度，而且对压电晶体，它不具有Δv/v效应，即在自由表面和金属化表面其传播速度是一样的，而压电晶体表面波及伪表面波均存在Δv/v效应。

Bacterial inoculants like rhizobia are the simplest to propagate and package.

细菌菌剂如根瘤菌是最容易繁殖包装的。

In the coating, the nodular defect was observed to worsen severely the properties. For testing under oxidation condition, the nodular defect results in the internal oxidation of Al. No single Al oxide scale may be formed at 1100℃ owing to consumption of Al. Under hot corrosion, it becomes as short-path for diffusion of S through the coating, thus sulphuring the coating together with the substrate. During thermal shock testing, it may act as the source of cracking, and moreover, if cyclic stress applied, the cracks propagate toward the substrate, the thermal fatigue properties of coating will be worsened.

结果表明：在氧化条件下，缺陷导致Al的内氧化，在1100℃时，由于Al的大量内消耗，涂层表面已不能形成单一的氧化铝膜，使氧化性能下降；在热腐蚀条件下，缺陷成为硫向涂层中扩散的通道，导致涂层及基体的硫化；在冷热疲劳条件下，缺陷成为裂纹源，在交变应力作用下，裂纹向基体中扩展，降低了涂层的热疲劳性能。

Assemblages of genes are used to build vehicles that carry them around, protect them and propagate them.

基因的集合被用于组装一些运输工具，而后者反过来又在运送、保护和传播这些基因。

Based upon the experimental results, including threshold values under static loading,the effects of alternating loading and room temperature creep,as well as metallographic observations of the fractography,it is concluded that notwithstanding stress corrosion or corrosion fatigue in aqua ammoniae,or fatigue in air,the cracks always initiate at the site subject to maximum normal stress(θ=-110°)along the notched surface,and then propagate along the maximum shear stress direction from that site(α=-35°).

由门槛值的测量、交变载荷的作用、室温蠕变的影响、断裂过程的金相观察及断口形貌等结果，可以确认；黄铜不论是在氨水中应力腐蚀或腐蚀疲劳，还是在空气中疲劳，裂纹都从Ⅱ型缺口试样的最大正应力处(0=-110°)萌生，并沿该处的最大剪应力方向(α=-35°)扩展。

It is feasible in the production to propagate the superior individual trees of Magnolia officinalis with improved cleft grafting.

首次利用改良劈接法快繁厚朴优良单株在生产上是可行的，成活率82.5％以上且苗木生长良好。

However, the original function that cotton carries seed to fly far to propagate is eliminated.

可是棉花当初携带棉种，飞扬远方传播种子的功能就消失了，或更精确地说，是已经做不到了。

Objective: To study the effect of polycythemia on blood oxygen saturation.

裴蕾目的：观察RBC剧增而引起的高粘血症对血氧饱和度的影响。

Based on SIMPLER algorithm in the curvilinear body-fitted coordinates, the calculations were performed for Pr=0.7, Re=10~1000 on non-orthogonal non-staggered grids which are generated by elliptic equation systems.
