In this paper the characteristics of tidal flow and seasonal variation of seidment content in the Hangzhou Bay and their affecting factors are studied. Field investigations and data analysis indicate that the sediment movement is mainly influenced by the Yangtze estuary and the sediment of the Yangtze estuary is induced by wind wave and tidal flow. Owing to the variation of dynamic conditions, the instantaneous sediment content is controlled by tidal flow, wind wave, depth of water and tidal range synthetically. A sediment content relationship formula is established with related factors. A non-equilibrium 2-dimensional numerical model of suspended sediment transportation is set up, and the finite element method is applied. The computation results of the model is in accordance with field data.

A new surface infiltrating composite technique has been developed to obtain metal and ceramic composite layer on the surface of metal by traditional casting method. It has been shown that with the new method, a composite layer with a thickness of 2-5 mm can be obtained. The ceramic particulates uniformly in the matrix. The composite layer is very favorable to wear resistance and thermal resistance situations.

为研究曲美他嗪（ｔｒｉｍｅｔａｚｉｄｉｎｅ）对猪心脏再灌注性心律失常的治疗作用，我们采用两组在体猪心脏（对照组ｎ＝９，用药组ｎ＝１０）左冠状动脉前降支（ＬＤＡＣＡ）完全阻断１０分钟，再灌５分钟，重复３次。结果显示：对照组心室纤颤（ＶＦ）发生率三次分别为８９％、６７％、３０％（Ｐ＜０．０１），ＶＦ潜伏期分别为１４．５±１．４ｓ、１１９．８±１３．８ｓ、４８±１２．５ｓ（Ｐ＜０．０１）。用药组ＶＦ发生率三次分别为４０％、３０％、３０％、（Ｐ＞０．０５），ＶＦ潜伏期分别为１５．２±６．４ｓ，１２６．５±１８．６ｓ，９７±２３．４ｓ（Ｐ＜０．０１）。曲美他嗪对猪心脏再灌性ＶＦ有一定的减少作用。

给大鼠戊四唑(PTZ)亚惊厥剂量(30 mg/kg,ip),每日一次,连续给药28 d.建立了戊四唑化学点燃模型。采用七点评分法观察行为惊厥和脑电图变化。凡连续5次获二级或二级以上惊厥者,被认为完全点燃。结果表明,28 d龄大鼠总点燃率为74%,全身性肌阵挛为其典型症状。行为惊厥与脑异常放电同步。凡有行为惊厥者皆伴有恼电图棘波或棘慢波放电。停止处理4周后。点燃大鼠仍保持其点燃状态。提示本文所用PTZ剂量合理,方法可靠且简单易行。

很多脂蛋白异常的病人发生早发性动脉粥样硬化和一些全身性疾病的危险性增高, 其中一些病人也可发生黄瘤,并成为脂蛋白病的皮肤标志。本文结合以前对脂蛋白病的概念对黄瘤提出新的鉴别诊断方法,并集中讨论脂蛋白代谢、含量或结构异常与发生特殊黄瘤之间的关系。黄瘤黄瘤病分两型:高脂血症性黄瘤病和正常血脂性黄瘤病。表现为黄色或橙色的斑疹、丘疹、皮下斑块或腱结节。
