Cavity flows both with and without sound excitation are studied by solving the 2 D time dependent Reynolds averaged Navier Stokes equations using explicit predictor corrector difference algorithm of Mac Cormack.

采用显式MacCorma－ck二步预估校正有限差分格式，求解二维雷诺平均非定常Navier－Stokes方程；并用Cebeci－Smith代数紊流模型作适当修正来模拟紊流效应，对有、无前缘声激励两种情况的空腔流场作了数值模拟，计算的振荡频率及振荡幅值都与实验结果基本符合，并且较好地模拟出了声激励对流场的影响。

RESULTS: The average reduction in exophthalmos was 4.51 mm (range, 3-6 mm; standard deviation,+/-0.95 mm). New-onset postoperative diplopia was observed in 1 patient.

结果：眼球突出的减少量平均为4.51毫米（范围为3-6毫米，标准差为+/-0.95毫米）。1例患者发生了新的术后复视。

The average age at onset of perforated NEC was 26 days. The most common clinical features were abdominal distention, decreased bowel sound and poor activity level.

The aim of the paper is to improve the reliability of HF generator, which is the key to decide the life of HF electrodeless light. At first, I collect and analyze the relative dates, and statistics fault models.

首先进行了与可靠性相关的数据收集与分析，对故障模式进行统计；然后从电路结构、环境应力及容差三个方面进行可靠性分析，从而为关键的可靠性设计提供了依据；接下来的可靠性设计，从电路设计、热设计、降额使用、筛选四个方面逐一解决了可靠性分析阶段发现的问题；最后，我将改良的发生器批量生产，并从中重新收集了可靠性数据进行计算，事实证明改良后高频无极灯的平均寿命已达到6万小时。

The general judgment of ferroelectrics perovskite stability using the tolerance factor and electronegative value of force difference,the stability of ferroelectrics perovskite can be well explained.

利用容忍因子和平均电负性力标差值作为钙钛矿稳定性的综合判据能很好说明钙钛矿稳定性。

Stratum near the bridge foundation is rhyolite porphyry in late Jurassic period. A little of slope eluvium exists on the top of the mountain, which is 200 m long and 80 m wide, and its all sides face to sea. The integrality of rock mass of the mountain is relatively poor because of the effect of some faults and other structural fissures.
