Two numerating methods are used in traditional structural design of gate chamber. First,considering the gate frusta to be fastened on the weir body,it is calculated as plane stress problem independently. Then applying the results on the bottom of gate frusta as concentrating load on the weir body,and the weir body is viewed as a elastic foundation beam or plate and unilateral stress analysis was performed.

传统闸室结构计算有两种计算方法，其一是将闸墩视为固端于堰体上，单独进行闸墩平面受力计算，再将闸墩下部的计算结果作为集中荷载作用于堰体上，堰体作为弹性地基梁或板进行片面应力计算。

In a same cloud band, the variation of temperature is small meanwhile the temperature is lower.The convective bubbles were observed in the warm clouds under the middle of the cumulostratus on 21,June 1992. The bubbles clearly show that they are one kind of mesoscale organization. It suggests that the synoptic system is situable to produce convective bubbles. Its contrastly analysed that the particle concentration and the liquid water content are higher.the particle spectra is similar,the particles captured by 2D-C probe are bigger in the bubbles.

1991年6月21日个例观测到对流泡位于层积云下部暖云中的部分，泡状结构明显，呈现出中尺度组织特征，天气系统的配置有利于垂直上升运动的发展：通过对比分析，发现对流泡内具有云滴浓度高、液态水含量较高、云谱型相似以及2D-C粒子尺度大等特点：本次个例观测到的对流泡内云滴谱表现为单峰型。

Some commonly agreed findings of legibility research include: text set in lower case is more legible than text set all in upper case, presumably because lower case letter structures and word shapes are more distinctive, having greater saliency with the presence of extenders (ascenders, descenders and other projecting parts); regular upright type is found to be more legible that italics, contrast, without dazzling brightness, has also been found to be important, with black on yellow/cream being most effective; positive images are easier to read than negative or reversed; the upper portions of letters play a stonger part than the lower portions in the recognition process; legibility is compromised by letterspacing, word spacing and leading that are too tight or too loose.

在易读性研究方面达成的共识包括：小写字母的文本要比全大写字母的文本易读，大致是由于小写字母的结构和词语形状更容易区分，特征更明显——带有延展性的笔画（ascenders上伸笔画， descenders下伸笔画、以及其他的伸展性笔画部件）；标准体字形的易读性要优于斜体；对比很重要——不要用那些耀眼的发光效果；在黄色/奶油色底上使用黑色文字最有效；阳文要比阴文易读；在识别过程中，字母的上部形状要比下部形状发挥更重要的作用；字母间距、词间距和行间距太密集或太松散也会降低易读性。

For the structure that the side-frusta is also used as retain wall,considering the side frusta fastened on the weir body,the plane stress is calculated at first. Then the moments,horizontal shear force and vertical force on the bottom of the retain wall are applied as fixate,and stress distribution on the weir body are calculated piecewise.

对于边墩兼作挡上墙结构，通常是将边墩视为固端于岩体上，先进行下端为固端的挡墙平面受力计算，再将挡墙下部的弯矩、水平剪力和垂直力作为集中外荷载进行堰体的应力计算，堰体也只能分段进行片面受力计算。
