normal proceed
2.It is necessary to proceed the normal distribution test before Pearson correlation is applied. Seventeen factors are classified into five groups by means of cluster analysis based on Kendall rank correlation coefficient as follows:(1) total dissolved nitrogen (TDN), total nitrogen(TN ),nitrite nitrogen (NO2-N ) ,ammoniacal nitrogen (NH4-N ), alkalinity (OH), conductivity (CON ), and chemical oxygen demond (CODMn ).
3.Proceed to the technique battlefield the test equipment reforms, increasing well-trained degree of the personnel, by using the concurrent technology and the critical path technology and establishing at the same time the wartime meets an emergency the test process especially the missile batch testing technology to optimize missile testing procedure that can increase the testing speed greatly and shorten the testing time, it can give some advice for the build of the technical position hereafter, also for future the design of the normal regulations guided missile with researched to manufacture to put forward the higher request.
