变小的

With the development of electrical design,higher signal frequency,smaller PCB board and bigger routing density,the signal integrity becomes more and more important.

摘 要：当今飞速发展的电子设计领域，信号频率的不断提高，印制电路板变小，布线密度加大都使得信号完整性问题越来越成为一个值得关注的问题。

Analysis of the time and space integral scales shows that time and length scales, TE and Lf, at the impact spots on the sidewall are larger than on the downstream side.

通过时间积分比尺TE和空间积分比尺Lf的分析，发现侧墙冲击点处的TE值较大，相应的Lf值也较大，冲击点下游孔和Lf很快变小，其规律与频谱分析一致。

There is much difference between the stress ratio in crown and springe calculated with these two methods. In the crown, most external forces changing into horizontal forces leads to the large decrease of the vertical tension stress. The vertical distribution pattern of the axial forces in the arch and soil pressure is not the same. And near the bottom of the pit the axial tension stress appears. Due to the self-accommodation effect which the external force acts on the arch, the stress in the springe gets lesser too.

拱冠和拱脚处的应力比值跟竖向构件比较相差悬殊；拱冠处由于大部分外力转化为水平拱内轴压力而使得竖向拉应力大大减小；竖向上拱内轴力与土压力的分布模式并不相同，并且在坑底附近出现了轴拉力；拱脚处也由于拱体对外力的自我调节作用而变得比纯竖向构件小的多。

The moons of Jupiter were produced by Galileo's spy-glass

把伽利略观察到的木星卫星说成是伽利略用他的小望远镜变出来的人们

Plaque size subjectively decreased in 15 (71%) of 21 men, and penile pain decreased in eight (80%) of 10 men.

主观上，21人中有15位(71%)的血凝块尺寸变小了，而10人的8位(80%)减少了阴茎的疼痛。

It is only because of the enormous unterstellar distance that so little material per unit of volume becomes so significant.

只是因为星际之间的非常大的距离，使得每分体积中很小的物质变得很可观。

The aircraft acceleration affects the response significantly, especially the vertical component of aircraft acceleration.

过大的垂直加速度分量或过小的水平加速度分量都可能使原稳定的系统变得不稳定。

The calculated result of the relaxed surface shows that the top layer atoms of ZrMn2(110) surface are arranged in an accidented plane and the space between atoms in ZrMn2(110) surface structure is decreased.

弛豫表面结构的计算结果表明表面结构的最表层为曲面，且表面结构的原子间隙变小。

The oxidation of solid biurea with chlorine in aqueous solution to produce azodicarbonamide was experimentally studied in a 1 L agitated glass vessel with a four-blade paddle stirrer. Based on the film theory, a model is first developed for this system by taking the gas-liquid and solid-liquid mass transfer, solid dissolution, and instantaneous reaction between the dissolved reactants into consideration.

在玻璃搅拌反应器中进行了固体联二脲与氯气液相氧化反应生成发泡剂 ADC过程的传质与动力学实验，提出了基于双膜理论的数学模型，以描述这一反应系统所涉及的气液和固液传质、固体溶解以及溶解物在液相中发生瞬间反应，特别是随反应进行固体反应物粒径变小导致固液传质速率减小的复杂过程。

Lateral branches penetrating leaf sheaths. Leaves alternate. Inflorescences borne at each node, opposite leaves, emerging from mouth of leaf sheath, each a large panicle of numerous cincinni; cincinni each subtended by an involucral bract; bracts similar to leaves, becoming smaller toward apex of cincinnus.

叶互生 花序着生在每节，与叶对生，从叶鞘口那里出现，每一个为一大的多数蝎尾状聚伞花序的圆锥花序；蝎尾状聚伞花序各自以一总苞片被包着；类似于叶的苞片，向蝎尾状聚伞花序先端变小。

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。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
