Test method for evaluating automotive spark - ignition engine fuel for electronic port fuel injector fouling by bench procedure 火花点燃式汽车发动机燃油电子口喷油器结垢的工作台评定试验方法
It can be propitious to exert the function of the scour and enhance the cleaning rate . 3 . the application of ozone 它不仅有利于洗涤剂作用的发挥，提高去污力，而且又具有辅助杀菌力防止结垢的能力。
Cyanide reductions to only 695 - 750 mgl have been reported , before heavy scaling at the anode prevented further electrolysis 据报道，在阴极大量结垢妨碍进一步电解之前，氰化物仅降到695 - 750毫克升。
Cyanide reductions to only 695 - 750 mg / l have been reported , before heavy scaling at the anode prevented further electrolysis 据报道，在阴极大量结垢妨碍进一步电解之前，氰化物仅降到695 - 750毫克升。
The serious troubles may be take place when the fouling is generated on main vapor valves , monitor valves and the valve 若主汽阀、调节阀以及抽汽逆止阀的阀杆上结垢引起卡涩，还可能导致汽轮机发生严重事故。
Standard test method for evaluating automotive spark - ignition engine fuel for electronic port fuel injector fouling by bench procedure Bench法评定电子口燃油喷射器结垢情况用汽车火花点燃式发动机燃油的标准试验方法
In order to ensure air compressor to run long and stably , enough attention must be paid to scaling phenomenon inside cooling system 为保证空压机长期稳定高效地运行，必须对其冷却系统内存在的结垢现象加以足够的重视。
In recent years , some physical techniques such as ultrasonic , electric field and magnetic field are also applied 由于地层水矿化度高、机械杂质含量高，使注水管网腐蚀结垢，导致注水系统能耗增大、生产效率降低，甚至影响正常生产。
