1) allowable value of vibration
振动容许限值
1.
Three aspects such as structure,equipment and human body are mostly influenced by the vibration problems in a building,in combination with existing standards of allowable value of vibration and testing value and analysis value,the present condition of the transfer station was wholly evaluated,and some feasible improvement suggestions for the existed problems were proposed.
针对振动问题对建筑物结构、机器设备、人体等三个主要影响的方面,结合现有振动容许限值标准及对结构的动力分析和振动测试结果,对本通廊转运站的现状进行了全面评估,对存在的问题提出了可行的改良化建议。
2) vibration tolerance
振动容限
3) allowable limit
容许限度,容许极限,允许限值
4) Permissible exposure limits

5) maximum permissible limit
最大容许限值
6) vibration limit value
振动限值
1.
The result indicates that both dynamic effect and rotary vibration effect should be highlighted in the design of steel structure frame, the requirement of allowed vibration limit value can be reached by taking the appropriate measures of damper design and vibration isolation.
结果表明 ,在钢结构框架的设计中 ,应重视动力影响和旋转振动影响 ,采取相应的减振设计和隔振措施可以达到允许振动限值的要
补充资料:电磁辐射限值
分子式:
CAS号:
性质:人体在电磁波照射下人的健康不致受到影响的界限值。中国规定,对于接触电磁辐射作业的作业者,在每天8h工作时间内,任意连续6min照射,全身平均比吸收功率小于0.1W/kg;对于一般公众,在一天24h内,任意连续6min照射全身平均比吸收功率小于0.02W/kg。中国对30~300MHz的超高频辐射和300~300 000MHz的微波辐射还有比较具体的规定。
