After graduation, he continued to work at the same institute, engaged in the research of shock wave propagation in solids, hyper-velocity impact and shock wave consolidation. He obtained PhD in applied mechanics from the University of Cambridge in 1998 with a thesis about constitutive relations and elastic waves for cellular solids modeled as a micropolar solid.

毕业后继续在力学所从事高温高压下固体中冲击波传播、高速冲击及爆炸冲击波压实金属粉末的机理研究。1998年获英国剑桥大学应用力学博士学位，论文研究胞状固体材料本构关系及微极材料中弹性波传播的问题。

在冠状窦起搏周长为300 ms和静脉给予1 mg/kg氟卡胺后，在房扑组病例中SD2均由上至下进行性延迟，指示第二个心房波激动主要是由间隔激动沿三尖瓣环逆钟向兴奋右房游离壁所致，显示出跨界嵴传导功能性阻滞。

According to this, the author applied wavelet transform to image restoration, enhancement, encoding, edge detection of the ultrasonic imaging well logging, and to attitude computation of tilted fracture and bed plane from well logging image.

在此基础上，将小波变换应用于超声成像测井图像恢复、图像增强、数据压缩编码、边缘检测以及倾斜裂缝和层面产状计算中。

This article is about thedifference of the ground movement, inspired by plane P waves riping into layeredalluvial valleys with fluid-saturated porous medium and solid dry-frame.

本文即为研究平面P波入射饱和土层状沉积谷地与同种土质的干土骨架所引起的地震地面运动差异。

Asian summer monsoon, one of the earth′s most energetic weather events, undoubtedly plays a key role in the variability of the general circulation. In this paper, through both calculation for the correlation coefficients between the monsoon indices and the geopotential height and the anomalous composite of the strong or weak ASM pentads, it is shown that the activity of the ASM...

本文通过夏季风指数与北半球环流的相关计算以及强、弱季风候北半球环流异常合成的分析发现，亚洲夏季风的活动会激发北半球夏季大气环流遥相关型，其主要相关中心均出现在季风区的下游地区，即从亚洲经太平洋至北美洲一带，除了表现出正负中心交替出现的波列状结构外，该遥相关型在太平洋地区还表现为一对南北向的偶极子异常型，我们将这一遥相关型称为亚洲太平洋北美型

Here, I introduce the Hubble classification system of galaxies, star dynamical in galaxy and the quasi-stationary spiral structure hypothesis of C.

其中介绍了星系的Hubble分类；对盘状星系研究的各种理论模型；星系内部的恒星动力学；林家翘、徐遐生提出的准稳密度波理论。

Any of several spore-bearing aquatic or marsh plants having short rhizomes and quill-like leaves; worldwide except Polynesia.

长有多孢子和羽状叶片的水生或沼泽生植物；广泛分布于除波利尼西亚以外的广大地区。

The fluid sediments imitating the rapidly deposited seabed silts were made in-situ, and an iron plate covered part of the test pit to cut off the effect of the marine hydrodynamics. By field-testing methods, such as static cone penetration test, field vane shear test, the variation of strength is measured at real time, and the marine hydrodynamics' impaction on the consolidation process of the sediments in the Yellow River Estuary was studied.

在黄河三角洲刁口叶瓣潮坪上，开挖2m ×1m×1m 的试坑，现场取土配置黄河口快速沉积形成的流体状堆积物，以铁板部分覆盖试坑隔绝波浪和潮流作用，利用微型贯入、静力触探、十字板剪切试验等原位测试手段，实时测定快速沉积的海床土强度，研究快速沉积的粉质海床土分别在自重条件下以及在波浪和潮波等水动力作用下的固结过程。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
