大学语文是大学生走向大学的第一课,它应当是大学母语教育与人文素质教育的起点,也必须是一个与中学语文有联系又有质的不同的亮点。大学语文教学应该在教学内容、教材选用、教学方法、教学手段、考核机制上有新的思考和选择。 相似文献

高压气吹除时机对潜艇应急吹除性能的影响分析 总被引:1,自引:0,他引:1
高压气吹除主压载水舱是潜艇水下动力抗沉的重要操纵手段之一。由于在高压气吹除主压载水舱的过程中,高压气不同吹除时机对潜艇的运动形式和姿态没有充分的理论研究和计算,导致在实际的高压气吹除主压载水舱过程中高压气吹除时机具有很大的随意性,严重影响潜艇应急吹除的性能。建立高压气吹除模型,运用计算机对艏部和舯部破损工况进行仿真计算并对结果进行分析,得出高压气吹除时机对潜艇能否够成功挽回起着关键性的作用。 相似文献

小高炮射击偏差观测的提前时间观测时机法与传统的等距法,两者的观测时机虽不同,精度也不同,但从原理上讲,都是一种近似方法,不能说哪个原理上有问题,哪个原理上无问题。从部队现装备看,在部队日常训练打靶中,前者的观测时机更易于把握,作为现装备的一种革新,有研究必要。 相似文献

The purpose of this paper is to investigate the problem of constructing an appointment template for scheduling patients at a specific type of multidisciplinary outpatient clinic called an integrated practice unit (IPU). The focus is on developing and solving a stochastic optimization model for a back pain IPU in the face of random arrivals, an uncertain patient mix, and variable service times. The deterministic version of the problem is modeled as a mixed integer program with the objective of minimizing a weighted combination of clinic closing time (duration) and total patient waiting time (length of stay). A two‐stage stochastic program is then derived to account for the randomness and the sequential nature of the decisions. Although it was not possible to solve the two‐stage problem for even a limited number of scenarios, the wait‐and‐see (WS) problem was sufficiently tractable to provide a lower bound on the stochastic solution. The introduction of valid inequalities, limiting indices, and the use of special ordered sets helped to speed up the computations. A greedy heuristic was also developed to obtain solutions much more quickly. Out of practical considerations, it was necessary to develop appointment templates with time slots at fixed intervals, which are not available from the WS solution. The first to be derived was the expected value (EV) template that is used to find the expected value of the EV solution (EEV). This solution provides an upper bound on the objective function value of the two‐stage stochastic program. The average gap between the EEV and WS solutions was 18%. Results from extensive computational testing are presented for the EV template and for our adaptation of three other templates found in the literature. Depending on the relative importance of the two objective function metrics, the results demonstrate the trade‐off that exists between them. For the templates investigated, the “closing time” ranged from an average of 235 to 275 minutes for a 300‐minute session, while the corresponding “total patient time in clinic” ranged from 80 to 71 minutes. 相似文献
