filter pressing

基本解释

The ever increasing volumes of image-based spam emails are bringing more annoyance to internet users, and how to filter it has become a pressing problem.
日益泛滥的图像垃圾邮件给互联网用户带来极大的不便，如何对其实施有效过滤成为亟待解决的问题。
Results showed that with increase of the pressure, filter-pressing period and flocculant(Polyacry Lamide, PAM) dosage, the filtrate volume increased obviously.
结果表明，随着压力的增加、压滤时间的延长和絮凝剂聚丙烯酰胺（PAM）投加量的增加，所得净滤液量均明显增大。
The coupling mathematical model between the vibration motors and the dynamic filter pressing device is established based on the mathematical model of the three-way asynchronous vibration motors.
并结合三向异步激振电机的数学模型建立了激振电机和动压机机电耦合数学模型。
