program gain
1.By use of some atom parameters in optical-field-ionized (OFI) plasmas obtained from the extended Cowan program based on Maxwell to suit any electron distribution with the help of additional program, the peak gain coefficient of Ni-like Kr system is calculated for the ion densities of 1×10 17 cm -3 and 3.2×10 17 cm -3 respectively after considering Doppler broadening and natural broadening. The theoretic peak gain coefficients of 14 cm -1 and 141 cm -1 are obtained respectively.
2.As a student of this program, you will gain knowledge of Communication; skills to make and release online news, skills to use computer and process data; ability to apply the communication principles to advertising, and public relations; understanding of the current stage and trends of the world online communication.
6.Answer: (1 ) build perfect and aseismatic take precautions against natural calamities to guarantee a system; (2) make and carry out an enterprise program of aseismatic take precautions against natural calamities and lash-up countermeasure; (3) had done seriously build a project the aseismatic consolidate of aseismatic fortify and original project and equipment works; (4) the conduct propaganda of knowledge of aseismatic take precautions against natural calamities mixes aggrandizement gain ground.
7.According to the inherent nonlinear characteristics of the acid-alkalititration curve,a PID control algorithm with separate-segment nonlinear variable gain is presented,and this PID controller in C++Builder program is designed using software. And then the PH Value Online Monitoring & Controlling System is established via the KingView and DDE of PID controller as well as the PLC.
