embedded figure
4.Abstract: For quick understanding the states of embedded places of instruments and their operation conditions so as to find and handle problems in time,by helping of some typical illustrations ,the problems of drawing complex safety-monitoring engineering graphs are emphatically resolved using software EXCEL97 ,including two longitudinal coordinate values versus a transverse coordinate datum for two curves in a same figure;exchanging position of independent variable(x) and dependent variable(y); different start-points or frequency of data series and drawing displacement nonitoring network etc.
