1) ground mooring
地面系留
1.
Helicopter rotor/fuselage coupled nonlinear dynamic model is presented in case of ground mooring.
对于无系留的模型旋翼来说,在任何转速下没有出现不稳定现象;地面系留时系统会呈现稳定响应、极限环以及大幅值振荡等非线性动力学行为,大幅值振荡将使系留索、接头和支持结构承受破坏性动力载荷。
2) balloon bed
气球地面系留台
3) Silurian formation
志留系地层
1.
Silurian formation is buried deeply in Yumen oilfield,combined with the high compaction and high pressure loss, it is difficult to bring the high-pressure-jet advantage into play, thus the average ROP in deep section is hardly to reach 1m/h.
玉门油田深井段钻速慢,特别是志留系地层,由于岩层压实程度高,受到井深的影响,压耗高,难以发挥高压喷射优势,使得深井段平均机速不到1m/h,为此引进自激式谐振脉冲射流。
4) ground elapsed time
地面停留时间
5) let a mulch top of the soil
残茬留在地面
6) surface detention
地面滞留;地面阻滞
