关于军用计算机在坦克部队维修保障问题的探讨

从全系统全寿命的观点来认识装备的维修性,呼吁有关单位在研制以计算机为核心的军用装备时,要同时考虑装备交付部队使用后的维修保障问题,防止出现装备买得起,用不了或用不起的局面。文章从维修保障的重要性、产品维修性设计和维修保障设计等几个方面提出一些看法,并提出一些参考作法。     

磁悬浮列车悬浮电磁铁设计研究

Biomedical applications of simulated environments

Environmental physiology assumes great significance in our national context in view of the diverse climatic conditions prevailing in different regions. Troops have to operate in diverse environmental conditions guarding the frontiers. Hence, the research in this area has been focused on the usage of field studies in the natural environments or simulated environments in the laboratory. Besides, the application of the simulation chambers in the research on the physiological effects of diverse environments, these studies may have applications in the control and management of certain clinical disorders. Some simulation chambers and specialised set-ups have been designed and developed at the Defence Institute of Physiology and Allied Sciences to carry out simulation studies. This paper describes these developments and the potentials of these biomedical applications of simulated environments.

Iraq's role in the 1973 Arab‐Israeli War

The events of the 1973 Arab‐Israeli War serve as an early indicator of Iraqi leader Saddam Hussein's willingness to use military power to address foreign policy concerns. In that war, Iraq intervened on the Syrian front with an armored division, other supporting units, and over 100 aircraft. This intervention, which occurred despite severe political and military difficulties, was larger than any previous Iraqi contribution to the anti‐Israeli struggle. Baghdad later asserted that Iraqi forces had saved Damascus from possible Israeli occupation, and these claims have been widely repeated by a variety of authors of different nationalities with various degrees of agreement or skepticism. Nevertheless, Iraqi claims to have saved Damascus from Israeli capture are false since the Israelis did not view the seizure of the city as important to their strategy for victory. Rather, the Iraqi presence on the Golan Heights was useful to the Arab war effort as one of many factors helping to delay the Israeli advance and prevent some important Syrian targets from being placed within artillery range of the Israeli force. Iraqi military shortcomings were well highlighted in this conflict, and many were repeated in the early stages of the war with Iran.     

Soldiers,the Frontier and the Politics of Command in British India

The defence of India in general and the North West Frontier in particular was central to strategic debate within the late Victorian army, creating one of the fault lines between rival factions competing for key commands and appointments. After a discussion of the varying strategic options debated within the British and Indian armies, the article examines the impact of Indian defence upon the ‘politics of command’ with particular reference to the appointment of Commanders-in-Chief in India between 1876 and 1892.
