在水中的

A new kind of magnesium alloys has been synthesized by high energy ball-milling of Mg and Fe mixed powders.Due to the high corrosion speed and reacting efficiency,the alloys are generally called super-corroding alloys.A SCA bulk is fabricated through cold-pressing and sintering the mechanically alloyed Mg-Fe powders.The chemical reaction of SCA with seawater rapidly releases heat and hydrogen gas,which may play very important roles in many ocean applications.For example,the reaction heat can be used to keep diver clothes warm;SCA corrosive links with the function of self-destruction can be utilized to control the sinking and floating of sonobuoy, and to salvage the training torpedo or other instruments.In addition,the reaction heat of SCA can be applied to heat food,machinery and ice or snow,which is thus very helpful for mountaineers.

超腐蚀合金采用Mg和Fe混合粉末，经高能球磨机械合金化、冷压、烧结，形成Mg-Fe合金块体，具有很高的海水腐蚀速率和反应效率，该合金化学反应放出的热量和氢气可在海洋工程中发挥重要作用，例如：可为深海作业潜水衣的保暖提供热量；由其制造的腐蚀链通过自毁机制，可用来控制声纳浮标的沉浮时间，打捞和回收水中的贵重仪器、装置以及训练用的靶雷；在偏远地区和寒冷地带，利用该合金的反应放热特性，不仅可加热机械、仪表或食品，而且能为登山运动员提供取暖所需的热量。

His college thesis was on the spectacled cayman; he lived in Gainesville, Florida, where alligators sun on the paths; his favourite work involved drifting, by torchlight, in a silent punt among the vegetation mats of the Mamirauá in Brazil or the llanos of Venezuela, with crocodilians darkly all about him, or looping them up on a six-foot pole to take DNA samples from them and massage their scaly necks.

他的大学论文就是写的有眼镜状斑纹的美洲鳄；他曾经居住的地方——佛罗里达州的盖恩斯维尔，鳄鱼在小路上晒太阳；借着手电的光亮，划着静行无声的平底船，在巴西的马尔马拉或委内瑞拉的亚诺斯河流植物垫衬的水中漂流，是他所钟爱的工作的一部分，其间，黑色鳄鱼遍及他的四周，或者，把鳄鱼环绕在一个6英尺长的杆子上，以采集它们的DNA样本，然后按摩它们那多鳞的脖子。

Metalsmiths knew how to detect forgeries of precious metals by measuring their density, using Archimedes' method of submersion in water to measure volume.

当时的金属匠利用阿基米德把物体浸在水中测量体积的方法，知道如何检测假的贵金属物品。

What has brought us here will lead us away; our ship sways in the tined harbor water.

The measurement of turgidity fresh weight takes much time and produces many test errors. In order to solve the problems mentioned above more accurately, a monomoleeular growth formula is adopted in this paper.With mathematic deduction, the formula to count the turgidity fresh weight can be obtained.

本文用单分子生长方程模拟植物叶片在水中吸水饱和过程，通过数学推导得到叶片饱和鲜重的计算公式：W=(W_1~2-W_0·W_2)/(2W_1-W_0-W_2)式中，W_T为饱和鲜重：W_0为起始鲜重；W_1为浸水t_0时间后的叶片重；W_2为再次浸水t_0时间后的叶片重。

A whole house unit or a counter filter that uses carbon filtration and ion exchange are ideal for getting rid of harmful chemicals in water.

一个整体房子单位或使用碳滤清和离子交换的逆过滤器对摆脱有害的化学制品是理想的在水中。

Total weight of dissolved mineral constituents in water per unit volume or weight of water in the sample.

在一单位容量或重量的水样本中，溶解于水中的矿物质成份的总重量。

In the industrial wastewater, there is 216.1 thousands tons of COD, which is 23.9% fewer than last year; discharge of venomousness pollutants (cyanide, arsenic, mercury, lead, cadmium, sexavalent chrome, volatile hydroxybenzene) is 92.85tons, 30.76% fewer than last year; oil discharges is 900tons, 1% fewer than last year; ammonia-nitrogen discharges is 8.6 thousands tons.

在工业的废水中，有 216.1 数千吨的雪，是 23.9%少于去年；有毒污染物质(氰化物，砷，水银，领引，镉， sexavalent 铬，挥发性 hydroxybenzene)的解除是 92.85 吨，30.76%少于去年；油解除是 900 吨，1%少于去年；氨-氮的解除是 8.6 数千吨。
