The propagation of non-sensitized IGC and the relation of IGC to potential values were investigated in sulfuric acid at ambient temperature.

用恒电位浸蚀方法在高压釜中研究了供货态316 L钢在尿素介质中发生非敏化态晶间腐蚀与电位区段的关系，并在常温硫酸溶液中研究了316 L钢非敏化态晶间腐蚀的发展过程及其与电位值的关系。

The results show that the highest yield strength and IGC resistance are obtained by 190 ℃/ 60 min retrogression and reaging. But when the alloy is treated near the lowest value of hardness curve of retrogression, the lowest IGC resistance is gotten by 190 ℃/4 min retrogression treatment.

结果表明：合金经190℃/60min回归和再时效处理，屈服强度最高，抗晶间腐蚀能力最好，具有最佳的综合性能；但合金在接近回归硬度曲线的谷值时，经190℃/4min回归处理，抗晶间腐蚀性能最差。

In order to restrain IGC,the solid solution temperature should be higher than 1 100 ℃ and then the tubes should be cooled quickly enough to avoid a lot of precipitation of Cr23C6 carbide at about 840 ℃,which lead to be sensitive to IGC of the steel.W...

试验结果表明，随固溶温度升高，晶间腐蚀敏感性下降，为抑制晶间腐蚀，固溶温度应≥1100℃；钢管固溶后应快速冷却，以避免840℃附近Cr23C6碳化物大量析出导致敏化；固溶温度超过1100℃，随固溶温度升高，晶粒度等级和室温强度逐渐下降。

Heating plate and immersion heater are conventionally adopted in digestion devices.

传统的方法使用平板或者浴式加热消解设备，前者存在温度精度不高、温度不均匀，后者则有样品间、样品和消解设备间相互干扰等问题。

All factors of production are mobile within the countries between clothing and food industries, but are immobile between the countries.

两个国家各自的制衣业和食品制造业间的各生产要素是非固定的，但这些生产要素在两国间是固定的。

BACKGROUND: Bone marrow mesenchymal stem cells of mice are different from human and rats. The difficulties of culture, sustaining impermanency activity of BMSCs after passage and short-term effect of stem cells tracking limited the study of mice.

背景：小鼠骨髓间充质干细胞培养不同于人及大鼠，培养扩展难度高，传代后干细胞活性保持时间短；又鉴于干细胞本身特点，使现有干细胞示踪方法作用时间短，这些因素均影响小鼠骨髓间充质干细胞的实验研究。

For stratified and cluster sampling with inappreciable differences, estimate precision becomes poor.

对于分层抽样和整群抽样，当群体间的差异、群内个体间差异均不显著时，其估计精度往往都很差。

This paper presents a finite element incremental substructure method inconsideration of nonlinear contact condition between elastic layers.

本文根据弹性层状体系层间接触面的实际状态，提出了一种考虑层间非线性接触的有限元增量子结构分析法。

The cases of strong and weak convection are selected based on the interannual variation of OLR. The different evolution characteristics of Qnet in this two cases also mostly owe to Qlat and Qsw. And Qnet should have some relation with OLR, because of their coherent variety that the increaser heat flux from the ocean to atmosphere relates to the enhanced convection.

Qnet在强、弱对流年间的差异随时间的变化同OLR在强、弱对流年间的差异随时间的变化可能有一定的相关性，表现在OLR 30-60天低频分量差异的负值区和Qnet差异的正值区基本一一相对应，表明大气从海洋得到的热量增加时，其上空的对流活动加强，数值上OLR和Qnet呈现较好的负相关性。
