Critical angle of refraction - semi-circular cylindrical mobile light source, the incident angle change the size of refraction angle to change at this time, when the refraction angle = 90 degrees, which is critical at this time angle of incidence angle, the critical angle of water at 40 degrees large about anything mobile source of water in the water screen that is a reflection of light, a phenomenon that total reflection.

光折射的临界角定义：光折射角=90度时，入射角即为临界角，按二方法，将半导体激光光源去掉铁夹，吸附在右下角的铁板上入射光对准中心，即产生折射光线，沿半圆形柱面移动光源，改变入射角的大小，这时折射角也改变，当折射角=90度时，这时入射角即为临界角，水的临界角大的在40度左右，再做移动光源在水中的水屏即出现反射光线，这种现象称全反射。

By the budgetary estimate of the water and heat conditions at the glacial equilibrium line and the water balance of lakes in the area of the West Kunlun Mountains during the late stadial of the Last Glaciation. before the summer mean temperature decreased by 1.5 C, the annal mean precipitation was 10-20% more than that of the present. As the summer mean temperature lowering was over 1. 5 C, the precipitation was decreased and the negtive of the lake water balance appeared.

文中还根据对西昆仑山区冰川零平衡线处水热状况及湖泊水量平衡状况的推算，指出末次盛冰期中，在夏季温度降低1-1.5℃以前，其年降水量应大于现代值，增加量大约在10-20％左右；在夏季温度降低值大于1-1.5℃以后，其降水减少，湖泊水量平衡出现负值，这与冰川、湖泊变化的地质记录所反映的早期冷湿、中期冷干气候条件相符。

Through analysis of the components of coking on different parts of desullfur system of single tower and the waste water containing sulfur , we find the cause of coking in the stripping desulur system from single tower is the polymerization reaction of carbohydrate and the separattion of varied solid powders, organic compounds, and all corrosive productions of metal out of waste water in high temperature, therefore,the solving method is how to decrease the oil content ,how to depolymerize form the carbohydrate and how to antisepticize by vapour of waste water.

对单塔脱硫系统中不同部位的垢物及现场催化含硫污水进行了分析测定，结果表明：塔内污垢成分及含量随塔体部位的不同而不尽相同，单塔汽提脱硫系统中垢物的形成，主要是由于污水中所含各类粉尘、有机物、金属腐蚀物等在高温下因石油碳氢化合物的析出及其单体的聚合反应所致。如何降低污水中的含油成分、减少聚合反应的生成、防止污水蒸气对塔体材料的腐蚀，是阻垢、除垢和防垢应解决的关键问题。

The first thing to see, looking away over the water, was a kind of dull line -- that was the woods on t'other side; you couldn't make nothing else out; then a pale place in the sky; then more paleness spreading around; then the river softened up away off, and warn't black any more, but gray; you could see little dark spots drifting along ever so far away -- trading scows, and such things; and long black streaks -- rafts; sometimes you could hear a sweep screaking; or jumbled up voices, it was so still, and sounds come so far; and by and by you could see a streak on the water which you know by the look of the streak that there's a snag there in a swift current which breaks on it and makes that streak look that way; and you see the mist curl up off of the water, and the east reddens up, and the river, and you make out a log-cabin in the edge of the woods, away on the bank on t'other side of the river, being a woodyard, likely, and piled by them cheats so you can throw a dog through it anywheres; then the nice breeze springs up, and comes fanning you from over there, so cool and fresh and sweet to smell on account of the woods and the flowers; but sometimes not that way, because they've left dead fish laying around, gars and such, and they do get pretty rank; and next you've got the full day, and everything smiling in the sun, and the song-birds just going it!

往 水面上望去，首先看到的是灰蒙蒙的一条线——那是河对岸的树林子——别的便什么也看不清——接着是天空中有一点儿鱼肚白；然后鱼肚白多了些，逐渐朝四周散开去；接下来，远处河水的颜色淡了些，不是那么黑了，而是灰灰的了。更远处，可以看到小小的黑点子在漂过来——那是些载货的驳船之类。还有黑黑的一长条——那是木筏子。有时能听到长桨吱吱地响，或者一些杂音。四周这么寂静，声音又来自很远的远方。过了一会儿，你看到一道水纹。凭了水纹的模样，你知道那里有一块礁石，急流朝着它冲过去，流水飞溅，成了这个模样。你看到，雾气袅袅上升，离开水面，东方红了起来，河面红了起来。你可以看到对岸河边树林子边上一处原木搭成的小屋，那可能是一个木材场，在那里堆着的一堆堆木材，中间却是空的，容得狗钻来钻去，为了能叫人家上当①。然后微风轻拂，从河上一阵阵吹来，那么凉凉的，那么清新，闻起来那么甜美，这是全凭了那些树林子和那些鲜花的缘故。可有时候也并非全是如此美妙。

Months, according to an official of the Indian Defense Ministry said that the history's first nuclear-powered submarine made a "No. chacra"(that is,"No. annihilate those who" with a displacement of about 5000 tons, submerged speed of 30 miles, containing members 100) will be July 26 in Andhra Pradesh, Vishakapatnam harbor sea trial, but shortly after India announced that the country's first nuclear-powered submarine made of the water time will be postponed until the end of July, but certainly no more than in August, it was measured degrees 10 years ago July 26, India and Pakistan in Kashmir's Kargil region of intense military conflicts took place, July 26 to choose the "No. chacra" into the water to the adjacent State the meaning of the demonstration is too obvious, so the option of delaying the launching of time - good time India did not directly dragged into the water on August 1, China's Army Day.
