3.when 1wt% Si is added into UDMH, there is slight improvement in the operational property of pro-pellant; and the total heat flux of the thrust chamber has been reduced about 33% .
4.In other way,running analyzed to the parameters on blood gas and ion of serum showed that the change of pH in 7.337～7.394 in 4 days did not excess the normal range,there was slight declined on HCO - 3、P CO 2 、ABE and K、Na、Ca(P>0.05) in heat stress。
