通孔玻璃材料的研制

研究了利用废旧玻璃用松装烧结和模压烧结方法生产通孔材料的可能性，以及原始粉末尺寸、烧结工艺和造孔剂添加量对通孔材料的密度和孔隙度的影响。实验结果表明，用废旧玻璃经松装烧结或模压烧结后可制得通孔材料；松装烧结时，随烧结温度提高，烧结保温时间延长，原始粉末粒度变细，烧结后通孔材料的密度增大，而孔隙度降低；模压烧结时造孔剂的最佳百分含量为５％～５０％，且通孔材料随造孔剂的百分含量增加，密度降低，孔隙度增大。     

Dynamic Simulation of a Smart Crank and Slider Mechanism

In this paper, a smart crank and slider mechanism is analyzed mostly from a dynamic view. By means of dynamic explicit finite element method, 3D nonlinear structure is simulated. It is proved that the mechanism can effectively accomplish smart movement prescribed. And in order to ensure reciprocal movement with higher frequency, measures should be taken to avoid over heating of parts. Compared with internal energy, kinetic energy of total rigid body is dominating, and Y direction equivalent rigid velocity is much higher than X direction velocity. Equivalent rigid velocity of all parts is consistent with respective movement condition. For both energy and velocity, slider effect is dominating. Three direction equivalent inertia force oscillates. Force amplitude in Y -direction is comparitively the greatest.     

Maritime accident investigation and temporal determinants of maritime accidents: A case study

This paper presents the results of an investigation into temporal determinants of maritime accidents based on a data-set obtained from the proceedings of formal inquiries in the former German Democratic Republic (GDR). The results show that there is no statistically significant outcome between the probability for an accident and the time of watch. Thus the results do not confirm previous studies, which reported significant time of day effects.The outcome of this study indicates that marine inquiries can provide useful data for an analysis of underlying causes of maritime accidents. It is suggested that accident inquiries should be extended into the area of watch systems employed and should record the hours of work and of rest of the officers on the watch involved in a maritime accident.     

The role of professional associations in shipping

This article is in three parts. The first covers the historical development of qualifying associations. The second covers the particular role of maritime institutions that include The Royal Institution of Naval Architects, The Institute of Marine Engineering Science and Technology and The Nautical Institute. The third and final section considers the future for maritime professional associations in the context of international shipping.

有限元和条分结合法计算边坡静力稳定性探讨

对于边坡稳定性计算通常采用不平衡推力法（如瑞典圆弧法和Bisho法等）和有限元计算方法，两者在计算本质上没有区别，但在计算过程中都存在不足。不平衡推力法在稳定性计算时要对潜在的滑面进行假设搜索，相对计算工作量较大，然而采用有限元分析的方法，在计算过程中往往由于判断收敛标准的不同，会出现不同的稳定性计算结果。文章利用两者的优点进行结合，分析计算得到边坡在静力条件下的稳定性。

葛洲坝各机组拦污栅进口流态及压差分析

本文以葛洲坝电厂原型观测为基础,在对坝前流态做整体分析的基础上,说明坝前流态对拦污栅污物聚集及对拦污栅水头损失的影响。对葛洲坝电站21台机组进行原型观测后分析得出:各机组拦污栅前后水位及进水口流态各不相同,因此造成拦污栅前后压差的原因也是不同的,不能一概而论,要具体问题具体分析。同时提出在以后的工程设计中要考虑坝前流态对电站拦污栅污物排漂的影响及防治。
