论高校学报“作者”和“参考文献”标注的规范化

我国的各种期刊杂志都在倡导各种规范的国际接轨。无论自然版（理工科）还是哲学与社会科学版（文科）学报研究会,都出台了相关规定。但是,我国高校学报编排规范化的问题却依然明显地存在着。其中,“作者”和“参考文献”标注问题更为突出。既然是规范,就必须在充分讨论的基础上整齐划一。     

弹载星敏感器动态测角补偿方法的研究

针对弹载星敏感器在测星过程中因弹体姿态变化带来的像移问题,提出了动态测角的补偿方法。首先,建立了星点相对图像传感器感光面匀速直线运动情况下的像元灰度分布的数学模型;其次,给出了测角补偿的原理及方法;最后,进行了仿真实验,结果表明,该补偿方法对星点在面阵图像传感器的感光面上的运动速度不敏感,补偿后的动态测角误差与静态的测角误差相差无几,补偿后的动态测角误差最大为2″。

Designing a screening experiment for highly reliable products

Within a reasonable life‐testing time, how to improve the reliability of highly reliable products is one of the great challenges to today's manufacturers. By using a resolution III experiment together with degradation test, Tseng, Hamada, and Chiao (1995) presented an interesting case study of improving the reliability of fluorescent lamps. However, in conducting such an experiment, they did not address the problem of how to choose the optimal settings of variables, such as sample size, inspection frequency, and termination time for each run, which are influential to the correct identification of significant factors and the experimental cost. Assuming that the product's degradation paths satisfy Wiener processes, this paper proposes a systematic approach to the aforementioned problem. First, an intuitively appealing identification rule is proposed. Next, under the constraints of a minimum probability of correct decision and a maximum probability of incorrect decision of the proposed identification rule, the optimum test plan (including the determinations of inspection frequency, sample size, and termination time for each run) can be obtained by minimizing the total experimental cost. An example is provided to illustrate the proposed method. © 2002 Wiley Periodicals, Inc.

Minimizing weighted earliness and tardiness penalties in single‐machine scheduling with idle time permitted

In this paper, a single‐machine scheduling problem with weighted earliness and tardiness penalties is considered. Idle time between two adjacent jobs is permitted and due dates of jobs could be unequal. The dominance rules are utilized to develop a relationship matrix, which allows a branch‐and‐bound algorithm to eliminate a high percentage of infeasible solutions. After combining this matrix with a branching strategy, a procedure to solve the problem is proposed. © 2002 Wiley Periodicals, Inc.
