static limit

Limit equilibrium analysis of the tailings dam static and dynamic stability.

对尾矿坝静力和动力稳定性进行了极限平衡法分析。

The deformation rate of magnetic pulse forming is 100-1000 times as that of the Quasi-static forming, and magnetic pulse forming can expand the forming limit of metallic materials effectively and lead to a series of improvements in materials' mechanical properties and microstructure.

磁脉冲成形的变形速率为准静态成形的100-1000倍。能显著提高金属的成形能力，同时，可使材料从微观组织到力学性能产生一系列的改变。

To change the limit of LPR test valve which need annulus pressure to keep static in opening period, a new model pressure controlled full bore testing valve which is applied for our oilfields' features is developed.

为改变目前LPR压控测试阀在开、关井过程中需要保压的局限性，研发了一种适应我国油田特点的新型全通径压控测试阀。
