丰富宜人的环境设计

发展园林绿化,丰富景观设计 　　在城市大环境下,绿化与建筑、绿化与城市空间的关系是相辅相成、相得益彰的.大连在沿袭传统的园林绿化手法的基础上,借鉴欧式造园手法对城市的一切自然特征,对山、海、土地、植被及其环境进行了全面“包装“,让人们视线所及之处都是生机盎然的树木、草坪和点缀其间的花卉、灌木、散石,这一切让人仿佛感受到欧洲的园林风光.而其间的委婉清丽又符合东方民族的审美情趣,创造了具有视觉美的开阔、通透、大气与豪放的与大连城市风格相吻合的外向型城市景观.……

梅毒螺旋体血凝试剂盒的研制

以超声波处理的梅毒螺旋体为抗原,致敏经醛化、鞣化处理的绵羊红血球,应用血凝试验检测梅毒患者血清中梅毒螺旋体特异性抗体。同时以国际上公认的标准方法——FTA-ABS作为对照试验。共检测1125份血清(其中梅毒血清205份,非梅毒血清920份).两种方法检测结果完全相符,即敏感性皆为100％,血凝试验的特异性为99％。     

Starting up the Sherritt Zinc Pressure Leach Process at Hudson Bay

The first commercial application of the Sherritt two-stage zinc pressure leach process commenced operation at the Hudson Bay Mining and Smelting Company metallurgical complex in Flin Flon, Manitoba (Canada), on July 2, 1993. The start-up was relatively smooth, and full design rate for the plant was achieved by September 12, 1993. Since that time, zinc extraction in the zinc pressure leach plant has consistently been in excess of 98%, and production has continued to exceed expectations. The successful operation of the Hudson Bay plant represents a significant advancement of zinc processing technology, especially with respect to meeting the environmental challenge faced by zinc plants today.

成藏流体历史分析——以黄骅坳陷三马地区为例

应用储集层岩石烃类流体包裹体研究方法，对黄骅坳陷三马地区沙一段油藏进行了重建成藏流体历史的尝试。对包体流体状态的分析表明，成藏流体具有高密度，高矿化度的性质，被捕获时的温度约为110－140℃，成藏流体的主要充注时期在明化镇组沉积期，距今为10－4Ma之前，充注成藏后的小幅度构造抬升中可能使原称油水界面以下的地层水矿化度发生变化，导致现今储集层流体矿化矿比包裹体流体矿化度明显下降。图5表2参6（钟宁宁摘）。     

Direct analysis of transient stability: Experience with the Taipower system

A direct method for transient stability analysis of a multimachine power system is presented. Emphasis is placed on the detailed development and evaluation of the proposed method in transient stability assessment. An energy-type Lyapunov function, taking into account the effect of transfer conductance, is introduced first. The potential energy boundary surface method is then adopted to determine the critical energy value quickly. The main computational burden in the direct method lies in the reduction of the admittance matrices. In this paper, an efficient reduction technique incorporating the sparsity technique and compensation theory is developed. Finally, the proposed method was tested on the Taipower system, which is the only power system in Taiwan. The results obtained confirm the validity and accuracy of the proposed method, and hence demonstrate the superiority and potential of the direct method in real power system applications.
