For the purpose to study its critical issues for fusion application, many kinds of V-W-Cr-Ti-Al alloys were developed, and were used for studies of recovery and recrystallization, aging behavior and precipitation hardening, high-temperature mechanical performance, effects of H on mechanical properties and hydrogen enbrittlement, H release behavior and oxidation behavior at elevated temperature. Mechanizms for the behaviors were analyzed and the relationship between chemical composition, microstructure and properties was established.

The results show that the effect of Li is to increase the rate of hardening, however, the addition of lithium does not progressively change age hardening and precipitation process of Al--Cu--Mg--Ag alloys with low Cu/Mg ratio, and significant age hardening response only occurs with the addition of 2.0\%Li.

结果表明，在Al--4.0Mg--1.5Cu--0.4Ag合金中添加锂，可以加速合金的时效进程，但其时效硬化效果并不能简单地随着含锂量的增加而逐步加强，只有当锂含量达到2.0\%时，才表现出显著的时效硬化与强化效果。

It has high saltwater corrosion resistance and better edge retention than austenitic stainless steel. 17-7PH is defined as a chromium-nickel-aluminum precipitation hardening stainless steel, a process that develops hardness at relatively low temperatures, allowing hardening with very little distortion.

它有很高的抗盐水腐蚀性和比奥氏体不锈钢更好的刀锋保持性。17-7PH被定义为经过铬、镍、铝沉淀硬化后的不锈钢，其加工工艺能在相对较低的温度下提高硬度，这是通过对其形状影响很小的淬水过程实现的。

This work could potentially enforce the related researches in interpolations of precipitation, and even other spatial climatic data.

地统计方法对于预测降水具有重要的价值，而不同的地区具有各自适合的模型，理解该方法的数学原理和操作过程，对相关研究具有借鉴意义。

The total precipitation for the law synthetic micrometres belt burr of Tansuanli (Li2CO3) and carbonic acid manganese (MnCO3) ball for damages caused calcine material prepared by a porous spherical type of spinel LiMn2O4 as a lithium-ion batteries positive materials, and through the valuable objects to the modified surface active agent, scattered porous ball into nano particles.

高手帮我翻一下。谢谢本文以共沉淀法合成微米级的带毛刺的碳酸锂（Li2CO3）和碳酸锰（MnCO3）球为前驱物通过高温煅烧而制备出多孔球状的尖晶石型LiMn2O4作为锂离子电池的正极材料，同时通过对前驱物加表面活性剂的改性，分散多孔球而成为纳米粒子。

The yearly precipitation in that region is 35 millilitres.

当然﹐在中译英前﹐最好先读些这方面的英文文章﹐可以知道英文是怎麼讲法。

This paper introduced an experimental study of polylacticacid nanoparticles of lipophilic anti-cancer herb drug using a precipitation method.

中文摘要：目的：探讨沉淀法制备载药聚乳酸纳米粒的过程及影响因素，为沉淀法的合理应用提供一定的理论依据。

On the basis of previous research and the authors' field investigations,it is thought that the complex geological structures,strong crust movements and rivers erosions,frequent earthquakes,abundant loose deposits,favorable geomorphology,well-developed modern glaciers and plentiful precipitation are the principal causes of triggering frequent mudflows in the study area.

根据前人的成果以及作者的实地调查，认为复杂的地质构造、强烈的地壳运动和河流切割、频繁的地震、丰富的松散堆积物、有利的地形地貌、现代冰川以及丰沛的降雨是研究区泥石流灾害频繁发生的主要原因。
