回顾性调查了五个铀矿山13360名职工15年(1971.1—1985.12)的死因并进行统计分析,探讨井下作业的主要职业危害。结果表明,井下作业职工与职业因素有关的死因是工伤、矽肺、肺癌。三者粗死亡率分别为55.37,14.20、17.47×10~(-5),平均寿命损失分别为3.55、2.41、2.89年。其他死因目前尚未见到与井下职业有害因素有相关关系。
Retrospectively investigated the causes of the death of 13360 workers in five uranium mines for 15 years (1971.1-1985.12) and conducted statistical analysis to explore the major occupational hazards of the downhole operations. The results show that underground workers and occupational factors related to the cause of death is occupational injuries, silicosis, lung cancer. The three crude fatality rates were 55.37,14.20,17.47 × 10 -5, the average life expectancy loss were 3.55, 2.41, 2.89 years. The other cause of death has not yet been found to be related to the harmful factors in underground careers.

【摘 要】实验室是各个学校的重要组成部分，由于具有设备仪器众多、价格相对昂贵、使用比较频繁、易损坏等特点，同时也是管理的重点和难点。传统的人工管理方式已经显得落后和效率低下，因此构建以微机为核心的实验室现代化管理系统势在必行。本文主要探讨如何构建和运行实验室现代化管理系统，从而对实验室的仪器设备、耗材、资金使用等方面进行有效的管理，从而达到顺利运行实验室，提高教学效率和实验教学质量的目的，文末提出
