COMPAREED WITH THE POETIC EXPERIENCES AND PHENOMENA WHASE NATURE HAS BEEN DETERMINED DURING THE LITERARY HISTORY, THE'THIRD GENERATION'POEMS, NOW STILL AFTER THE AGITATION, AND TRYING FOR CERTAIN FIRM TRANSFERENCE, ARE RATHER LIMITED IN DEALING WITH HISTORY AND THEORETICAL SIGNIFICANCE, WHETHER ON TIME SPAN OR SPIRITUAL LEVELS. THIS PAPER, THEREFORE, LAYS EMPHASIS ON DESCRIPTION AND INTERPRETATION AS WELL AS PRUDENT VALUE JUDGEMENT, INSTEND OF ARBITRARY DECISION. A MORE THOROUGH STUDY WILL HAVE YET TO BE WAITED WHEN THE'THIRD GENERATION'HAVE GONE A MORE FULL AND COMPLETE DEVELOPMENT.

The effective channel mobility of4H-SiC MOSFETs is increased significantly by high temperature anneals in nitric oxide.4H-SiC MOSFET with hydrogen postoxidation annealing has a lower threshold voltage of3.1V and a wide gate voltage operation range in which the inversion channel mobility is more than100cm 2 /Vs.

SiC的雪崩击穿电场是Si的十倍，因此，理论上SiC单极功率器件的导通电阻可以比Si器件的低400倍，但在6H-SiCMOS结构中，由于反型层的电子迁移率较小，沟道迁移率测量值仅为40～50cm2/Vs，远远低于6H-SiC的体迁移率400cm2/Vs眼1熏2演，限制了SiC功率MOSFET的导通电阻Ron。

Process and mechanism of electrodeposited Zn-Fe-Si02 composite coatings were studied, including some contents as follow: Potential-pH plots of Zn-H2O and Fe-H2O systems were drawn, and the thermomechanical analysis was made. Results showed that the region of zinc and iron's codeposition was wide, which provided theoretic basis for electrodepositing Zn-Fe alloy. But the balance potential of zinc was greatly different from iron's, so in order to make zinc and iron codepositing, some complexant must be added into electroplating solution.
