腐蚀性的

First, the speed of the reaction between mud acid and rock is very fast, the effective distance of acid is short, active acid can not reach deep formation.

首先，高温下常规土酸与地层矿物反应速度极快，酸液有效作用距离短，活性酸不能到达地层深部；其次，HF与铝硅酸盐的化学反应不是简单的一次反应，其副产物氟硅酸和氟铝化物还可与铝硅酸盐发生二次反应和三次反应，形成一系列不溶性的沉淀物，对储层造成严重伤害；第三，高温情况下酸液对井下管柱及工具腐蚀性很强，对缓蚀剂性能要求高。

Due to we use high quality aluminous material which has high compressive rigidity and corrosion resistance, so it can be used for walls, floors, shower room and etc.

由于我们用的是高品质的铝材料，有着很强的抗压力和耐腐蚀性，所以它可以被用于墙面，地面，淋浴房，等等。

Sepiolite is a kind of nonmetal clay, which has capacity of high adsorption, causticity resistant, heating stability, salty resistant and so on. In this paper, we aimed at developing it's huge potential in environmental protection.

海泡石是一种富镁非金属粘土矿，其原矿比表面积达，有较好的吸附能力、良好的耐腐蚀性、热稳定性、抗盐性等特性，本文旨在开发其在环境领域内强大的应用潜力。

The oxygen is the metals that the water supply main causticity the material boiler of the system and boiler would decay the thermodynamic energy system for aquatic deliquescence oxygen.

氧是给水系统和锅炉的主要腐蚀性物质，锅炉给水中的溶解氧会腐蚀热力系统的金属。

Through such assembling connection, the normal pressure meter is enabled with measurement of pressure of such mediums subject to solidification that have strong causticity, high temperature, high viscosity, and solid floating objects.

通过这种配接，使一般通用型的压力表增加了测量腐蚀性强、温度高、粘度大或含有固态浮游物、易凝固的介质压力的能力。

Sulfuric acid, which is much stronger, is so corrosive that it is seriously damaging to the human skin.

硫酸则是强得多的酸，具有很大的腐蚀性，会严重损伤人的皮肤。

Acids are chemical compounds that, in water solution, have a sharp t aste, a corrosive action on metals, and the ability to turn certain blue ve getable dyes red.

酸是一种化合物，它在溶于水时具有强烈的气味和对金属的腐蚀性，并且能够使某些蓝色植物染料变红。

The optimum conditions were obtained as follows : the weight ratio of fatty acids of rapeseed oil and 85%acetic acid is 1:4, ozonolysis temperature is 20-25

本文使用植物油脂肪酸为原料，原料丰富，价格低廉；使用含水溶剂不但提高了产品收率，而且降低了溶剂挥发性和溶剂的腐蚀性；使用活性炭吸附壬二酸粗品大大提高了壬二酸纯度，此方法简便易行，用此方法处理壬二酸粗品，壬二酸的纯度可达96.1%。

Alcohols, ketones, esters, alcohols, ethers common media are methanol, ethanol, ethylene glycol, propanol, etc., ketones medium with acetone, methyl ethyl ketone, etc., there are a variety of methyl esters of medium, ethyl ester, ether medium with ether, ethyl ether, butyl ether, etc., they basically did not corrosive materials can be used for the specific use of the property should also be under the media and related requirements to make reasonable choices.

醇类、酮类、酯类、醚类常见的醇类介质有甲醇、乙醇、乙二醇、丙醇等，酮类介质有丙酮、丁酮等，酯类介质有各种甲酯、乙酯等，醚类介质有甲醚、乙醚、丁醚等，它们基本没有腐蚀性，常用材料均可适用，具体选用时还应根据介质的属性和相关要求做出合理选择。

Compared with the traditional 2000 and 7000 series a-luminum alloys, 1420 Al-Li alloy decreases density by 12% and increases Young's modulus by 8%, and has excellent corrosion resistance and high temperature properties.

1420铝锂合金与传统的2000、7000系列铝合金相比，密度低12%，弹性模量高8%左右，具有优异的抗腐蚀性和高温性能。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
