aftertime
1.Han dynasty was one of the important periods of ethical systematization. "Not loyal joined law", which could chastise the action of "non-loyal", has great impact on aftertime.
2.This paper introduces the measurement methods and results of CDQ-Boiler system for mass and energy balance diagnosis, analyses the technologic economic index at the different product rate, puts forward the measures of decreasing the ratio of coke burning, improving the heat transfer conditions and realizing the optimized control aftertime.
3.Develop a strategic implement greatly along with the west, our country in aftertime grow very will start to constructing a center of gravity to change direction the west region the orbit transportation inside a period.
4.The PCB design of CCD camera system is combined. The three factors of EMC are introduced and analyzed how to control EMC from the point of EMI. The points that muse be take care are indicated, and accumulated experience for practice aftertime.
5.By setting up the database of operating parameters of ECM(electrochemical machining) and the datasheet for cathodedesign,studyying the basic process law of ECM, this paper solves the twomost problem restrictting the extend and development of ECM, namely thetechnique is difficult to be holded and the cathode is difficult to bedesigned. It has build groundwork for establishing expert system of ECMand realizing the process control of ECM aftertime.
6.Rare earth superlong afterglow luminescnet material SrAl?2O?4∶Eu??2+?, Dy??3+? was synthesized by high?temperature solid state reaction with SrCO?3, Al?2O?3, Eu?2O?3 and Dy?2O?3. The excitation spectra, the emission spectra, the brightness and the aftertime of the luminescent material were detected.
