五、請將下列英文譯成中文：（20 分） 
 The oil to be cleaned is continuously fed to the purifier. Separated sludge and water accumulate at the periphery of the bowl. Normally a sludge discharge takes place at specific time intervals, but if the water contamination is high, an earlier discharge may be initiated. When separated water reaches the disk stack, some water escapes with the cleaned oil. The increase in water content is sensed by a water transducer installed in the clean oil outlet. When the water content in the cleaned oil reaches a specific "trigger level", the control program will initiate an automatic discharge of the water in the bowl. The water is discharged with the sludge through the sludge ports at the periphery of the bowl.
