1) under-voltage
欠压
1.
Damage brought by canceling the under-voltage (no-voltage) release of low-voltage breaker and its solutions;
取消低压断路器欠压(失压)脱扣功能的危害及对策
2) over-voltage/low-voltage
过压/欠压
3) undercompaction
欠压实
1.
The porosity of the former decreased exponentially, while that of the latter maintains a constant which is conventionally mistaken as undercompaction period.
传统理论把压缩阶段称做欠压实阶段,是一个误解。
2.
Water is easily preserved in the pores and forms the undercompaction of the mudstone layer.
当泥质沉积物成岩以后 ,地层中部的孔隙水必须克服微孔隙对其产生的启动阻力才能向外排出 ;否则 ,地层水就被滞流在岩层孔隙中并造成泥岩的欠压实。
3.
Mudstone undercompaction phenomenon is one of the important characters of Eocene strata in the Dongtai depression of the Subei basin.
泥岩欠压实现象是苏北地区 ,特别是苏北盆地东台坳陷下第三系地层中重要的地质特征之一。
4) undercompaction region
欠压实区
1.
The forming of lithologic reservoir is episodic in the special range of undercompaction region.
在欠压实区的某些特定范围内,岩性油藏的形成过程具有典型的幕式特征,有效烃源岩的幕式排烃和烃源岩区内砂岩体的幕式聚烃是两个相对独立但又彼此联系的过程。
5) Uncompaction
欠压实
1.
Research on inclusions and mudstone compaction curves shows that uncompaction and structural compression are the main factors resulting in abnormal high pressure in Early Cretaceous gas reservoirs.
包裹体结合泥岩压实曲线研究认为,该区早白垩世气藏存在异常高压,欠压实和构造挤压作用是其形成的主要因素:在断裂带以南欠压实起主要作用,在断裂带构造挤压起主要作用,在断裂带以北两者作用相当。
6) uncompacted belt
欠压实带
1.
But this does not mean that all the present uncompacted belts are now still high pressure or superpressure belts.
欠压实带是因地层具异常高压形成的 ,但这并不能完全代表现今欠压实带就一定为高压 (超压 )带 ,因为古高压 (超压 )在地质历史中 ,可能因诸多原因己释放。
