operational life span meaning in Chinese

使用寿命

For the purpose prolong the operational life span , overstress is prohibited because the elastic cell is subject to damage , while the elastic cell shall be kept working within its elastic range , so as to ensure the accuracy of measurement
为了延长仪表的使用寿命，避免弹性元件因受力过大而损坏，同时弹性元件应工作在弹性范围内，以保证测量的精度。
The realization of this scheme not only can improve the working and living condition on the platform but also can prolong its operational life span . this is bond to bring huge economic profit to offshore engineering , so it has a promising future . to validate the effectiveness of this vibration control method experimentally , a real control system is made to control the vibration of an oil platform model under simulated wave loadings and the experiment will be conducted in the next term
根据理论分析结果，本文后面又针对一个近海平台的实验模型给出了该模型在模拟波浪载荷作用下的振动控制系统设计方案，并进行了系统设计，用于将来的实验模型振动控制实验，以验证文中所设计变刚度调谐质量阻尼器对由波浪载荷引起的平台振动的控制效果。
