以40型面粉机圆筒筛为研究对象，建立相应的力学模型，通过理论结合实际，设计螺母锥度，在螺母与圆筒筛之间采用同锥度错位配合，将钢筋的径向受力通过锥面分解到钢筋轴向一部分，使得钢筋在轴向和径向都保持尽可能小地受力。

To analyze the pseudo phenomena caused by migration velocity error, the paper firstly studied the depth error between post-stack migration and prestack migration caused by same velocity error, and found the depth error was only relative to velocity error and had no direct matter with methods of depth migration (post-stack migration or prestack migration). Then the paper did numerical simulation of a complex lenticular body model with wave-equation modeling and migration, and found that the velocity error could not only induce depth error, but also could change the modality of construction and the event of subjacent layers. Furthermore, it could change the frequency of reflective event. They are the pseudo phenomena caused by migration.

从分析偏移速度误差带来的各种假象出发，本文首先对比分析了速度误差对叠后深度偏移和叠前深度偏移的影响，发现偏移剖面的深度误差仅与速度模型的误差有关系，与具体的偏移方法没有直接的关系；然后对一个复杂的透镜体模型进行了波动方程叠后正演和偏移计算，详细地讨论了不同的速度误差带来的各种假象，发现速度误差不仅会带来深度误差，而且会造成构造体的形态变化，下覆地层同向轴的扭曲，还可能引起地层同向轴的频率发生变化，给资料解释带来一定的假象。

Based on the analysis of sequence stratigraphy and seismic stratigraphy of carbonate platforms, especially to the ones in Dongsha and Xisha, this dissertation has identified, for the first time, three major and several minor drowning events of the platforms since Tertiary. Drowning events in the four carbonate platforms, especially in Dongsha Platform, coincide with major global eustatic cycles raised by B.

在经过高技术处理的地震剖面上，淹没层序的特征是顶部同相轴呈光滑的双轨连续强反射，特殊处理后表现出高波阻抗、高密度和强瞬时振幅等特征，还表现为高的速度梯度值和高的剩余速度梯度值，甚至在局部区域出现本层层速度比下部地层层速度高的现象。

The gathered groups of plant quadrates in the space of DCA ordination are consistent with the result of TWINSPAN,and this revealed a relationship between plant for...

DCA结果同TWINSPAN分析结果比较一致，并且较好地反映了植物群系和环境之间的关系，其中第1轴明显地反映出各个群系的水热梯度的变化，同时也反映出坡向的变化趋势；而第2轴则反映出海拔的梯度变化，表明群系所在地的海拔是决定群系分布的主要环境因素。

As the inner and outsider baskets rotate at the same speed, the inner one, pushed by the piston, reciprocates axially and repeatedly. As a result, pusher plate pushes the cake layer in the inner basket to move out of it and then into the outside basket for further separation , a ring layer of cake being formed,while the outside section of the inner basket pushes the cake layer in the outside basket to move continuously out of the outside basket and then discharge it through the slot for scraper.

内、外转鼓同速旋转的同时，在活塞推动下，内转鼓连续轴向往复运动，因而推料盘推动内转鼓滤饼层间歇不断地向外移动排出内转鼓，进入外转鼓进一步分离并形成环形滤饼层，内转鼓外端面则推动外转鼓滤饼层间歇不断地向外移动排出外转鼓，经刮料槽排出机外。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
