- Influences of recycle and second grade water spraying on semi dry flue gas desulfurization efficiency have been experimentally investigated.
- It can be compacted in dry state by vibration, easy dismantling after use, and more than 40h of durability.
- N/med tuberculosis bacili falls in dry state, also have the comfortable stress of heat-resisting.
- The disappearance and transfer behavior of polychlorinated biphenyl (PCBs) (the mains of penta PCBs) at higher concentrations (400 mg/kg) bestrewed into semi field soil systems were studied under near field conditions (semi dry climate in North China).
利用构建的土壤半野外试验系统 ;在接近野外 (半干旱气候 )条件下 ;研究高含量 ( 4 0 0mg/kg)高氯代PCBs(以五氯代为主 )在系统中的迁移与消失规律 .
- Keeping flexibility and softness in dry state without becoming dry and hard; no wetting process is needed.
- Elastomeric ring ligature is not suitable for sliding of brackets and wires in the dry state.
