黄河下游稳定主槽之节点整治

稳定主槽是当前黄河下游河道治理的关键。窄深河槽具有很强的泄洪能力与输沙能力,是主槽整治追求的目标。黄河下游均是顺直微弯河道,河道水流最基本的主导机理是沿着阻力最小的方向流动,走直路、走近路,主槽整治设计流路应以顺直为上策。当前有必要对微弯整治方案进行再认识,实现对其否定之否定的提高。控制性弯道整治、对口丁坝整治、节点整治都属于双岸整治的范畴,对双岸整治的方向应予肯定。今后的整治应从微弯整治向节点整治发展,逐步过渡到以节点整治为主,最终达到稳定河势流路、高效排洪输沙之目的。     

训练中齐射尾流自导鱼雷碰撞问题及对策

为满足当前潜艇部队训练的需要，针对尾流自导鱼雷齐射训练中可能出现的碰撞问题，以鱼雷散布为基础，分别对齐射时鱼雷进入尾流前发生碰撞，鱼雷过目标舰时与目标舰发生擦碰以及双雷齐射时两雷进入目标尾流后双雷碰撞的3种可能发生的情况进行分析，提出了采用两雷齐射时，设定1条雷的”操雷航程”，以避免两雷交叉，对两雷设定不同”海况”，使两雷航行在不同深度以及两雷反方向发射等避免碰撞的修正方法。该方法易于操作，可为尾流自导鱼雷安全训练提供有效保证。     

建立虚拟武器装备库，从基础践行科技兴训——浅探VRML技术在我军军事训练中的应用

VRML技术作为现代一种新型计算机技术，已广泛应用到军事、教育等各个领域，充分运用现代高新技术成果，进行模拟训练已成为各军事强国在训练改革的重要目标和现代军事训练发展的指导方向。本文初步探讨了VRML技术在我军军事训练中的应用，提出了虚拟武器装备库的概念，并对我军建立虚拟武器装备库的可能性、必要性及建设构想进行了初步探讨。     

与时俱进 加快发展高职教育 推动我国工业化快速发展

当前,我国正在实施工业化的发展战略,要加快工业化的发展,必须大力发展和加强高等职业教育。在高等职业教育发展上,要实现从注重量到既注重量更注重质的转变;在培养方式上,要实现从只重技能到既重视技能又重视可持续发展能力培养的转变;在培养目标上,要实现从培养学生能力到培养复合型人才的转变。     

Does anticipation training affect drivers' risk taking?

Skill and risk taking are argued to be independent and to require different remedial programs. However, it is possible to contend that skill-based training could be associated with an increase, a decrease, or no change in risk-taking behavior. In 3 experiments, the authors examined the influence of a skill-based training program (hazard perception) on the risk-taking behavior of car drivers (using video-based driving simulations). Experiment 1 demonstrated a decrease in risk taking for novice drivers. In Experiment 2, the authors examined the possibilities that the skills training might operate through either a nonspecific reduction in risk taking or a specific improvement in hazard perception. Evidence supported the latter. These findings were replicated in a more ecological context in Experiment 3, which compared advanced and nonadvanced police drivers.

做人贵在清白,做事必须认真,做学问要敢于好高骛远,善于实事求是

结合自身的学习、工作经历，与研究生畅谈如何学会“做人、做事、做学问”。     

Managing information technology in the nineties

Business, not technology leaders should manage the change of Information Technology (IT) from a self-contained business support unit of the sixties to a distributed strategic business function of the nineties. Top management should recognize that a good business plan can only be developed and executed through the partnership between the business unit managers and the managers of the financial, the personnel, and the IT resource units. The technical problems associated with the management of IT may again be the easier part of the total management challenge.
