When the is 0.1mol/l, ratio / is 0 or 4, aged at 95250℃ for 24 hours, anatase and rutile TiO〓 particles are formed respectively; when the ratio / is between 0 and 4, mixture of anatase and rutile TiO〓 particles is formed, the high the temperature the more the rutile phase. When the / is 5, aged at below 200℃ for 24 hours, amorphous product is gained, aged at 250℃ for 24 hours, olive-like TiO〓 particles with brookite structure are formed.

Ti〓=0.1mol·L〓时，95～250℃陈化，/比为0时，得到金红石型TiO〓颗粒，/比为4时，得到锐钛型TiO〓颗粒；/比介于0～4，可得到金红石型与锐钛型混合二氧化钛颗粒，温度越高含金红石型成分越多；/比为5，200℃以下陈化，得无定型产物，250℃陈化得橄榄形单分散板钛矿型二氧化钛。

The progress of the cell cycle of Spodoptera frgiperda IPLB-Sf21-AE clonal isolate 9 (Sf9) cells was directed by Flow cytometry analysis.The results showed that the whole time of the cell cycle was about 18 hours and the gapes between every two phases were about 6 hours.At 12-18 hours post AcNPV infection,Sf9 cells were arrested in G\-2/M phase.When the cells in G\-1/S phase synchronized by druge were infected by AcNPV,2/3 of the cells was in G\-2/M phase and 1/3 of the cells in S phase.
