查询词典 uranium dioxide

Carbon dioxide emissions in the process of cotton-growing are around 1 kg; Carbon dioxide emissions in the production from cotton to ready clothing are about 1.5 kilograms; Carbon dioxide emissions in transportation process from cotton fields to factory, then to retail end are about 0.5 kilograms.

买件衣服也会增加碳排放？买件衣服也会增加碳排放？听起来不可思议，可这就是现实。棉花种植过程中排放的二氧化碳约为1千克；从棉花到成衣的制作环节会排放1.5千克；从棉田到工厂再到零售终端的运输过程排放的总量约为0.5千克

A:The content increment of the carbon dioxide in the atmosphere: It imply various complicated composition in the fuel, at burnable after produce various harmful material, even not the fuel with miscellaneous quality attains the complete combustion, also wanting to produce the water and carbon dioxides, positive because the fuel combustion makes the carbon dioxide in the atmosphere density increased continuously, breaking the balance of the nature carbon dioxide, to go to and may cause" green house effect", cause the Earth air temperature rise.

一：大气中二氧化碳的含量增加：燃料中含有各种复杂的成分，在燃烧后产生各种有害物质，即使不含杂质的燃料达到完全燃烧，也要产生水和二氧化碳，正因为燃料燃烧使大气中的二氧化碳浓度不断增加，破坏了自然界二氧化碳的平衡，以至可能引发&温室效应&，致使地球气温上升。

The impure carbon dioxide which can be obtained from any available source of carbon dioxide will typically contain as impurities sulfur compounds such as carbonyl sulfide, hydrogen sulfide, dimethyl sulfide, sulfur dioxide and mercaptans, hydrocarbon impurities such as aldehydes, alcohols, aromatics, propane, ethylene, and other impurities such as water, and carbon monoxide.

可由任何二氧化碳源得到的低纯度二氧化碳通常含有以下杂质：硫化合物，例如硫化羰、硫化氢、二甲硫、二氧化硫和硫醇；烃杂质，例如醛、醇、芳族化合物、丙烷、乙烯；以及其它杂质，例如水和一氧化碳。

The carbon dioxide produces the main way is fossil fuel massive burning, now mainly through enhances the fossil fuel the energy use factor, the use low-carbon or the non-carbon emerging energy took the fossil fuel the substitute, as well as the carbon dioxide collection and the storage realize the carbon dioxide to reduce the platoon.

二氧化碳产生的主要途径是化石燃料的大量燃烧，现在主要通过提高化石燃料的能源利用率，使用低碳或无碳的新兴能源作为化石燃料的替代品，以及二氧化碳的收集和储存来实现二氧化碳的减排。

The adsorption rate of uranium increased with increase of initial concentration of uranium and temperature.

考察了吸附温度、溶液的pH和浓度对吸附性能的影响。

Based on the analysis results and the principle that the concentration of the contaminants in a mine varies in a constant ratio and the degree of their hazard varies in an arithmetic progression,the evaluating indicators were determined for the air quality in a uranium mine,and an evaluation model was proposed for the evaluation of the air quality in a uranium mine based on integrated scale index on ...

该模型克服了传统评价方法主要从辐射危害的角度进行评价的局限，能综合评价铀矿山井下空气的质量。采用该模型对某铀矿井4个用风点的空气质量进行了评价，获得了4个用风点空气质量综合评价等级和应采取的相应的对策。评价结果能为铀矿井通风系统的设计和空气质量的安全评价提供参考。

I was struck by the fact that the activity of uranium and thorium compounds appears to be an atomic property of the element uranium and of the element thorium .

我突然意识到，铀化合物和针化合物的这些活性似乎是元素铀和元素钍的原子属性。

And some discoveries happen by accident. Radioactivity came to light a century after the discovery of uranium when Henri Becquerel used uranium salts and photographic plates in the same experiment and found that one fogged the other.

而有些发现是在偶然间发生的：在铀被发现后，放射学已经出现世纪有余；亨利·贝克勒尔使用铀盐和照相板做同样的试验的时候发现两者可以雾化在一起，于是铀出现了。

Radioactivity came to light a century after the discovery of uranium when Henri Becquerel used uranium salts and photographic plates in the same experiment and found that one fogged the other.

放射性是铀发现一百年之后才被贝克勒尔发现，他在同一个试验中使用了铀盐和显像版，结果发现前者是后者变得模糊。

Radioactivity came to light a century after the discovery of uranium when Henri Becquerel used uranium salts and photographic plates in the same experiment and found that one fogged the other .

在发现铀一百年之后，亨利·贝克勒尔在一实验中同时使用了铀盐和照相底片，发现两者会相互遮盖，从而使放射现象亮相于世。

It's bell can reach over a meter in diameter.

它的身体最大可以达到直径1米多。

Now they are overdue and I shall have to pay a fine.

现在他们过期了，我不得不付罚款。
