Methods: The motion of parasternal papillary muscle anterior wall, inferior wall, posterior wall, and lateral wall were detected by 2DE at short axis view of left ventricle before PTCA, 3 d and 1-3 months after PTCA in 33 cases of patients with coronary heart disease, who received PTCA+stent at selected time. Peak systolic velocity of subendocardial, subepicardial and middle layer myocardium, transmural velocity difference of the same segments and Outer lateral mitral valve annulus were also detected at apical 4 chamber view by pulsed wave tissue Doppler imaging.

In the process of wave slamming, the impact pressures with short duration and high peaks occurs when the waves hit the subface of the structure, which causes the destabilization of superstructure and the fratigue failure of joints.

在波浪冲击过程中，当波峰刚接触到建筑物底面时会产生历时很短但强度极大的冲击压力，这种极强的冲击荷载会引起建筑物上部结构的失稳或造成结构连接处的疲劳破坏。

Under confused sea condition, the structures may subject to very strong w ave impulsive 1oad due to slamming by the wave with significant crest when waves propagate underneath the structure and surge up to its subface. Previous studies indicate that impact pressures are characterized by an initial peak pressure of considerable magnitude but of short duration occurs, followed by a slowly-varying uplift pressure of less magnitude but of considerable duration, and which typically is first positive, then decreases to zero and becomes negative, In hostile sea state, the peak pressures may cause the damage of the horizontal members of the structures or make the whole superstructure collapsed.

若这些海上建筑物的上部结构底高程较低，在恶劣海况下当大波浪在其面板下面通过并与之接触时，面板下面除了作用有强度变化较缓慢的波压力外，在波峰刚接触到面板时尚存在着历时很短但强度极大的冲击压力，这种极强冲击荷载会引起建筑物的整个上部结构失稳或造成局部破坏。

The design movement parameters of Nanhai FPSO were selected according to the results of short crested wave theory in ballasted condition.

南海FPSO设计运动参数选择以短峰波压载状态下的计算结果为依据。

In this paper, the new powersource for short circuiting transfer was researched and based on the technologyof DSP and wave control.

本课题以波控技术为基本指导思想，应用DSP，将CO_2焊短路过渡过程细分为七个阶段。

According to the equivalence of traffic forecasting and function estimating and approaching,the essay puts forward a method of short-term traffic forecasting which is based upon wave decompounding and support vector regress.

基于交通流预测问题与函数估计和逼近问题是等价的的思想，提出一种基于小波分解-支持向量回归的短时交通量预测方法。

A 众 knows to all, a that a short subject 《 of the Louis 斯 cloth 努艾尔 is a peaceful reach the 鲁 dog 》 inside razor blade incises to grow in person's eyeball, weird lens that successful in career hair etc., founded the surrealism cinematic first river;4, cinematic base in tide in new wave.

所众周知，1928年西班牙人路易斯布努艾尔的那部24分钟的短片《一条安达鲁狗》中刀片切割人眼球、口中长出头发等的怪异镜头，开创了超现实主义电影的先河）；4、新浪潮电影的根据地。

If possible, store extra supplies of any prescription drugs you need and the basic medicines and first-aid items that might run short in a wave of pandemic flu — such as over-the-counter fever drugs, rehydrating solutions and plastic gloves.

比如非处方退烧药，补水剂和塑料手套。

Results: The surface of discs showed dim, shallowing wave-like structure in short indentation time, while in long indentation time we found gel losing, collagen bundles disclosing and cave-like damage.

结果：短时压缩使关节盘表面波纹状结构变浅、模糊；过长时间压缩可使其凝胶层脱落，胶原纤维束暴露或洞样缺损，尤其在关节盘中带。

The amplitudes of forward and backward travelling wave caused by a fault were integrated respectively within a short time after fault. The fault direction was determined by the ratio of the integral values.

该方案基于故障发生后一段时间内，正向行波幅值积分与反向行波幅值积分的比值来确定故障方向。
