Forecasting Capillary Characteristics for Aluminum Nitride Ceramic ― Liquid Metal Systems

A test has been devised that allows one to determine the work of adhesion and wettability in a system composed of aluminum nitride ceramics with a liquid metal without the need for experimental examination. A correlation is examined between the work of adhesion on the one hand and that criteria or others on the other that have been proposed by various researchers. Forecasts are made for the work of adhesion and wetting angle for a series of metals that have not been examined previously. An experimental check has been made on the forecast adhesion activity for some elements.

Review of Counseling and psychotherapy of work dysfunctions.

Reviews the book, Counseling and psychotherapy of work dysfunctions by Rodney L. Lowman (see record 1993-98413-000). Dr. Lowman's book on work dysfunctions serves as a seminal product for further understanding a much-neglected component of the lives of the many men and women who seek psychological assistance in working through issues around their employment. The book conveys in a well-written, sometimes humorous, style that "work is a natural part of living, and the issues it raises are important parts of character." The overall impression is that of a well-thought-out and most readable book. There is no doubt in this reviewer's mind that it will become essential reading for psychologists, social workers, family therapists, and graduate students who are becoming increasingly involved in this field of study. What this reviewer found very helpful was the clarity of presentation of the assessment techniques as well as the amply illustrated intervention modules that may be utilized. To this reviewer, there is no doubt that this is one area for psychologists' contributions in the future--the work area. Lowman's book gives us basic material from which to continue to build our profession in a new and exciting direction. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

两种求解可靠指标的实用算法

介绍了基于几何原理求解可靠指标、寻找设计验算点的具有较高实用价值的两种新算法： 图解渐近法和Monte Carlo递进法。推导了由标准正态变量反算常用分布类型的随机变量数值的计算公式，并且通过采取某些改善措施，简化了计算过程，大大提高了问题的求解效率。同时，两种算法可以结合使用，经算例验证，能够快速解决问题且满足高精度要求，说明了本文方法的可行性和有效性。     

工艺空气压缩机组开车过程的思考

通过汽轮机组调速系统伺服马达不复位、主汽门不动作，反推出电磁阀控制线路接线错误，用人为短路压力开关等手段判断出组合油脱扣器活塞卡涩是造成现场延误开车的根本原因，提出完善大机组开车工作票制度、提高人员素质等措施。     

液动旋冲接头冲击功测试方法研究

液动旋冲接头性能参数是旋冲接头设计的主要依据之一，如何对液动旋冲接头的参数进行检测是非常重要的工作。在分析和比较了测试液动旋冲接头性能参数各种方法的基础上，选择了冲击力法来进行破岩液动旋冲接头的性能参数测试，以YD系列测力传感器为检测元件，建立了一套比较完善的自动检测系统。分析了影响单次冲击功测试的因素，得出了测试旋冲接头的性能参数的影响规律。
