Under the condition of sinter raw material in existence in PZH Steel,sinter mineralogical structure must be improved and it makes sure that sinter contains much more SFCA and makes hematite and the SFCA melt into interlaced structure if PANGANG'S sinter tumbler index is improved.

After the commissioning of AnYang Steel 360m2 sintering machine,the sinter tumbler index was lower and its fluctuation was higher,and this sinter could not fulfill the requirement of BF.

According to several typical operation modes of Fujian power system and using the sensitivity index and margin index of voltage stability,the static voltage stability is analyzed and the system voltage stability after n 1 check is also discussed.

The determination of critical irrigation time may be accomplished by using a sensitivity index ( λ i ) that is the se.

Sensitivity method is a steady-state voltage stability analysis method based on power flow equation,and it analyses system stability by the system variable sensitivity index to the disturbance under conditions that the system is disturbed.

A systematical study is made on the sensitivity index regarding transition between raining and nonraining weather in nonflood season of Guangxi, and on the diagnosis accuracy of precipitation at moderate and above levels in the same term.
