A Gaussian equation with four eigenvalues was proposed and applied to the crosslinking reactive extrusions of mPE and LDPE in a twin-screw extruder to elucidate the rules of their macroscopical mixing based on another Gaussian equation with three eigenvalues. It was found that the regression results of the Gaussian equation with four eigenvalues to the residence time distribution (RTD) curves of the crosslinking reactive extrusions of mPE and LDPE were more precise than that of the Gaussian equation with three eigenvalues，but these two kinds of Gaussian equations did not have definite physical meanings. For these reasons，we proposed a double main-flows plus single backflow cell model (revised DBFC model，named as RDBFC) according to the structural characteristics of the twin-screw extruder，which can describe the RTD curves of the crosslinking reactive extrusions of mPE and LDPE more satisfactorily because its eigenvalues all have definite physical meanings.

The crosslinked PTMPS-DMS networks were prepared by hydrosilation and the BPO thermal crosslink process respectively. TG，DSC and isothermal gravimetric analysis at 300℃ showed that the crosslink process had great impact on the thermal properties of the crosslinked networks. The BPO thermal crosslinked network，which began to degrade at 480℃ in air，possessed much higher thermo-oxidation stability than that crosslinked by the hydrosilation process，which began to degrade at 368℃ in air. The Tgs of these two networks had no significant difference，which were －55℃ and －49℃，respectively. It showed that the catalyst H2PtCl6 greatly decreased the thermo-oxidation stability of the PTMPS-DMS networks.

A new flat strip-insert with elliptical teeth and notches was developed to solve the problem of rapid fouling growth and reduced heat transfer coefficient at a low flow rate in heat transfer tubes. The notches were distributed and staggered on both sides of the strip. An oblique tooth followed each tooth. Thus, the fluid flowed spirally. It was just like the flow when twisted strip with oblique teeth was inserted in tubes. Such spiral flow enables the flat strip-insert to self-rotate and remove fouling on tube wall at a low flow rate. Much strong vortex was produced behind each elliptical tooth, which were distributed uniformly, so convective heat transfer was enhanced greatly. The tube side heat transfer film coefficient increased by two times in comparison with that without any insert. The enhancement was more than simple twisted strip by over 5 times. The flow resistance coefficient was much higher than that of simple twisted strip, but the overall equipment resistance was not high and was in the range of engineering application. The new flat strip- insert with elliptical teeth and notches can be made through injection molding. The manufacture cost was low and the quality was quite good. It can be put into mass production and used widely in heat transfer equipment.

It is a good way for the chemical industrial park to take wastewater into recycle，save resource and reduce pollution.
