Acta Metallurgica Sinica(English Letters) 2000年第1期13卷 319-327页

作者： R. Boman and J. - P. Ponthot( LTAS - mc&T - Continuum Mechanics and Thermomechanics, University of Liege, Belgium)

In this paper, the lubrication problem in nmmerical sindation of forming processes is *** enumerationg the difficulties encountered when trying to solve such a problem with the finite element method, a generalization of the formaulation of Liu[4-6] for the thin film hydrodynamic lubrication re- gime is presented. This method is then aplied to a strip rolling simulation,using the Arbitrary La- grangian eulerian (ALE) formalism.

Acta Oceanologica Sinica 1994年第2期13卷 275-283页

作者： Rong Shoubai, Shi Shumei,mc Qirong, Liu Shaeqiong,Liang Ze,Zhao Xiuzhu, Tong Wangdong Li Shouwu and Li Yimin

In order to induce tetraploid into Jinjiang oyster (Crassostrea rivularis), embryos were treated with physical (cold or heat shock) and chemical (chlorpromazinum or traditional Chinese medicine)methods in the first 3 min before the cleavage of zygotes or at the onset of the first cleavage of one or two eggs. Measurements show that the induction rates of tetraploid in the embryos inspected are 28%, 30%, 28. 4% and 35. 8% for heat-shock (39℃, 3 min),cold-shock (10℃, 3min),chlorpromazinum (0. 375 mg/dm3, 10 min) and traditional Chinese medicine (50 g/dm3 )extract (57 cm3, 10 min),respectively. The tetraploid induction rate in the larvae treated with traditional Chinese medicine is 32. 5%.It is evident that the induction rate of tetraploid in embryos insected at an early stage is the most remarkable when treated. with traditional Chinese medicine.

0　引言美国杜邦公司正在开发包覆金属的芳纶并将它注册为“Ａｒａｃｏｎ” ,这种纤维可以加工成诸如信号传输体、编织电缆、屏蔽用品、电业用装置和防电磁干扰的基础材料。芳纶比同类合成纤维尼龙和聚酯纤维的热稳定性有显著改善。此外 ,芳纶 (Ｋｅｖｌａｒ)的强度特别高而重量却很轻 ,其模量与普通金属导体在相同的数值范围内。这些特性使得芳纶成为理想的可包覆金属导体的基材。芳纶在应力作用下蠕变非常小 ,耐拉伸和曲挠疲劳 ,在一定的温度和冷冻条件下均保持常温下的强度。尽管芳纶对包括润滑油和燃料油在内的多数化学品稳定 ,但对强酸、强碱的作用非常敏感。为什么覆盖金属的芳纶还表现出格外的柔软性和像纺织品那样的可加工性呢 ?这是因为每一根包覆金属的纤维非常细 ,其断面直径只相当于54美国线规 (ＡＷＧ)。表 1所示数据表明包覆金属的芳纶纤维的比重介于铝和铜之间。本质上讲 ,制造以芳纶为基本材料的可导电产品工艺上可以采用缝制的办法 ,且在物理性能、机械性能、电性能和热性能方面实现了全新的平衡效果。表 1　不同材料的比重材　　料比　　重铜 8 9镍 8 9锡 7 3银 10 5铝 2 7包覆金属的芳纶纤维 2 0～ 5 01　结...
