tip grain

Based on the analyses of vertical seal mechanism of fault for oil and gas and its influence factors, this paper established the relations among oil migration velocity and grain of filling materials, tip angle and mudstone content of fault zone by physical simulation experiment.

在断层垂向上封油气机理及影响因素分析的基础上，通过物理模拟建立了原油通过断裂带运移速度与断层填充物粒度、倾角和泥质含量之间的函数关系。

On the basis of the tests, this paper discussed the fracture behaviour of the para-macroscopic concrete which include crack tip, grain boundary, defect and nearby aggregates.

本文以实验为手段，讨论了混凝土准宏观局部断裂特性，这里的准宏观包括缝尖、界面、缺陷以及数个骨料构成的区域。

The stress at star tip of grain was maximal, which is liable to failure.

星尖处的应力最大，是发动机药柱容易失效的部位。

Based on the study of oil percolation migration mechanism through fault zone and its influencing factors, physical simulation was made on the oil percolation migration characteristics through fault zones with different grain sizes, shale contents and tip angles using experiment equipment designed and installed by ourselves.

在研究原油通过断裂带渗滤运移机制及主要影响因素的基础上，利用自行设计组装的模拟实验装置，对原油通过不同粒度、泥质含量和倾角的断裂带的渗滤运移特征进行了物理模拟。

Meanwhile, the tip of precipitates along grain boundary becomes obtuse, the alloying elements are depleted in the region near the grain boundary and the stress corrosion resistance is bettered.

同时，晶界沉淀物的端部由尖锐变得圆钝，晶界临近区域中的合金元素贫化，使材料的应力腐蚀抗力提高。

Tip: Hulled or "whole grain" barley is the most nutritious.

贴士：未脱壳或“全麦”大麦是最有营养的。
