To similinear hyperbolic system, we use interpolated coefficient FEM and get similar results as the linear one.

对于一阶半线性双曲组，我们对半线性项插值系数有限元方法，得到了和线性问题类似的结论。

The results showed that the microstructure of hypereutectic high-chromium cast iron is significantly influenced by temperature of slurry.

试验结果表明，半固态浆料温度对试样的半固态组织有明显的影响。

ABSTRACT The solidification process and the mechanism of spray formed hypereutectic Al-Si alloys has been investigated in this dissertation.

半固态触变成形是喷射沉积快速凝固材料走向实用的一个重要的发展方向，本文研究喷射沉积高硅铝合金的半固态触变成形的基本规律，揭示喷射沉积高硅。。。

The effects of process parameters on microstructures of hypereutectic Al-Si semi-solid slurry were investigated.

摘 要：研究超声振动制备过共晶Al-Si合金半固态浆料中工艺参数对半固态浆料组织的影响规律。

The impact toughness of samples with semi-solid microstructure was measured and quantitative compared with that of normal hypereutectic high chromium cast iron.

也对半固态高铬铸铁试样和正常态高铬铸铁试样进行了冲击韧性试验，并通过定量比较，总结和分析了冲击韧性值随半固态浆料温度的变化以及影响因素。

Under certain temperature of slurry, the semi-solid microstructure with certain shape and size was obtained, with which both impact toughness and wear resistance of hypereutectic high chromium cast iron were enhanced.

在合适的半固态浆料温度下，可以制备出具有一定尺寸和形状的半固态组织，不仅有利于提高过共晶高铬铸铁的韧性，而且也有利于提高其耐磨性。

The main manifestations of the semi-exterior and semi-interior syndrome are alternative appearance of cold and heat symptoms, fullness and oppression in the chest and hypochondrium, irritability, nausea, anorexia, bitter taste in the mouth, dry throat, blurred vision, wiry pulse.

半表半里证主要表现为寒热往来，胸胁苦满，心烦欲呕，不欲饮食，口苦咽干，目眩，脉弦。

During the course of the short-cycle correlation, This paper assembleds the descending cycle of early cycle and the ascending cycle of late cycle, which are conjointed together , begin to correlate and draw the ichnography . By this method , writer can consider the two connected sandbodies as one unit to analyse , and can contact the sand units of exploitatition in the oilfield. Then analyse the distributing and the continuity of the sandbodies in the medium-cycle, the distributing and the continuity of oil and gas in the short-cycle.

每个中期旋回包括 3-4 个短期旋回，在短期旋回的对比中，将垂向上相邻的早期短期旋回的下降半旋回和晚期短期旋回的上升半旋回组合到一起进行对比划分和平面成图，这使得相邻两套的粉砂岩作为一个单元进行分析，与油田开发中的小层紧密的结合到一起。

In chapter 1, we simply introduce the background and the present state of the theory of semirings; for the sake of convenience, we introduce some fundamental knowledge about idempotent semirings.

第一章，我们对半环理论研究的背景、现状和幂等元半环的基础知识作了简要的介绍。

The class of idempotent semirings is a very important class of semirings. Many experts and scholars thorough, painstakingly and systematically investigate it.

幂等元半环是一类非常重要的半环，许多专家学者对其进行了深入细致的系统研究。
