For the cracking of ethane, we commonly use ( ) to represent its cracking depth. Rate 98. The sign of the characteristic factor is ( ), and it is a factor that characterizes ( ). 99. When the turbine is in operation, steam passes through the impeller from front to back, doing work on the impeller and converting its own ( ) and ( ) into mechanical energy for the rotation of the impeller. 100. A control loop is composed of ( ), ( ), and ( ). 96. The two main factors affecting the selectivity of ethylene in the cracking reaction are ( ) and ( ). Average residence time, average hydrocarbon partial pressure: 97. For the cracking of ethane, we commonly use ( ) to indicate the degree of cracking. Conversion rate: 98. The sign of the characteristic factor is ( ), and it is a factor that characterizes ( ). Chemical composition or properties of K or UPO-K crude oil and distillates. 99. When the turbine is in operation, steam passes through the impeller, doing work on it and converting its own ( ) and ( ) into mechanical energy that drives the impeller to rotate. Pressure energy, thermal energy. 100. A control circuit is composed of ( ), ( ), and ( ). Detector, regulator, pneumatic actuator
