It has the advantages of small-volume, light-weight, beautiful-outer-appearance, unnecessary of air-compression, and can be ground-mounted or suspended; it is also easy to be operated, with switching on button, it can be operated. Furthermore, it is controlled by infrared ray. It has alarming lights.

Experimental results showed that AB-8 resin possesses higher absorption and desorption capacity. The appropriate adsorption conditions were: the range of the sample concentration was 0.6~1.0mg/ml, pH was 4.28 or so and velocity of flow was 3ml/min. When 95% ethanol was used as eluant, the desorption capacity was 97%, and 4 BV eluant could desorb FSPV basically.

In this paper,the raft is approximated by a thin plate with regular shape at first.Then the floating raft system is divided into several subsystems,such as plate raft,elastic foundation,etc,which are respectively modeled by four-parameter net method.After that,dynamic absorber and active absorber are put into a uniform frame to obtain the model of plate raft subsystem coupling with them.At last,according to the force and velocity relationship among each subsystem\'s interfaces,the entire plate floating raft system is modeled by subsystem structural admittance synthesis method.As the main structure of floating raft system is elastic,it is inevitably to study the optimization of actuators\' mounting positions before designing control law.In this paper,two new criterions are proposed for it.
