癌胚抗原测定对宫体恶性肿瘤诊断及预后的意义

用放射免疫法测定了子宫体恶性肿瘤组３６例，子宫体良性病变组４６例，正常组５０例的子宫内膜、晨尿、血清的ＣＥＡ含量。结果示子宫体恶性肿瘤组３种标本的ＣＥＡ含量均值高于２对照组，而子宫体良性病变组与正常组间无显著差异。血标本ＣＥＡ升高的阳性率于良恶性病变组间无差异。子宫内膜ＣＥＡ含量与子宫体恶性肿瘤的临床分期呈正相关。子宫内膜ＣＥＡ含量可能与恶性肿瘤的预后有关。同时测定３种标本ＣＥＡ值有助于区别子宫体良、恶性病变。     

Core competence and competitive strategy of the Taiwan shipbuilding industry: a resource-based approach

The shipbuilding output for Taiwan had been 4th in the world until 1999; however, at that time, it dropped to the 9th. Currently, the world shipbuilding capacity greatly exceeds the demand and this disparity could grow to 40% by 2005. Facing this turning point, the main objective of this study is to re-examine the international competitive position of Taiwan's shipbuilding industry; furthermore, to realize the industries' core competences and attempt to recommend competitive strategies for the future development of Taiwan's shipbuilding industry. The results show that Taiwan's main core competence is production management, mainly through heterogeneous resource analysis. This paper also proposes that for general types of ships, Taiwan's development priority should be to utilize low-cost strategies to occupy the market continuously; as to high value added types of ships, Taiwan's priority should be to utilize differential and focus strategies. Finally, the direction of government policy is suggested.     

A fuzzy multicriteria model to evaluate the privatization of the public bus operations

A double model based on fuzzy synthetic decision and a fuzzy multicriteria decision is presented for this study. In a basic level decision, we use a fuzzy synthetic decision to reduce the sub-criteria calculation work. In a higher level decision, the approximation reasoning allows the decision maker to make his best choice. These methods are more in accordance with the thinking processes of the human mind when complex issues are involved. Therefore, this paper will use a fuzzy linguistic approach, instead of the traditional approach to avoid the interference of the numerical estimates for weight and performance of alternatives. In the end, a heuristic algorithm for the evaluating process is developed and demonstrated in a case study.

免疫治疗反复自然流产患者77例分析

对我院1988年11月至1993年2月门诊77例不明原因的反复自然流产患者进行免疫治疗,并经人类白细胞抗原（HLA）组型测定,发现含有相同人类白细胞抗原的反复自然流产（RSA）患者的治疗效果显著（74.07％）,而不含相同HLA抗原者疗效较差（39.13％）,两者有显著差异（P<0.01）。采用皮内注射丈夫淋巴细胞和输入丈夫全血免疫治疗较用自身淋巴细胞皮内注射效果显著（P值分别为<0.01与<0.05）。提示对不明原因的RSA进行免疫治疗,方法简单,疗效满意。

THRO1a制冷剂在汽车空调中替代R12的研究

THRO1a制冷剂是一种绿色环保型产品，从制冷剂性质要求方面分析了THRO1a替代R12的可行性。通过对比试验可看出，在不对汽车空调系统做任何改动的情况下，用THRO1a替代R12，制冷能力与原R12系统相当。实车替代对比试验证明，THRO1a替代R12后，在制冷效果方面基本相同或略有改善。

基于研磨子的车轮多边形抑制机理与跟踪试验

提出了基于研磨子的车轮多边形抑制措施,即通过研磨子摩擦车轮踏面从而消除或抑制车轮多边形的产生和发展。台架试验表明,研磨子在保证对车轮踏面均匀磨损的前提下,可有效降低车轮表面粗糙度等级。在线路运用跟踪试验中,配置研磨子车轮的高阶多边形幅值保持在-12.0～7.2 dB之间,表明修形研磨子对车轮多边形的抑制效果明显。     

城市轨道交通网络限流方案的制定与评估及其应用

限流是应对高峰时段的超负荷运行以及突发事件大客流冲击时的一种有效的客运组织方案。从限流的定义及作用分析出发,提出了限流方案的制定原则、实施条件、实施方法和评价指标,并对上海轨道交通网络的限流方案与实践效果进行了总结与评价。目前限流方案的制定主要依靠运营管理人员经验,其全局性和动态性等方面的考虑明显不足。
