Purified GO had a molecular weight between 145, 000 and 162, 300, as determined by Sephadex G-200 filtration and SDS-PAGE of the enzyme as cross-linked with glutaraldehyde. This result showed that the holoenzyme was a tetramer, and no change occurred in molecular weight of the enzyme during the s〓orage. The active form of GO from brassica leaves showed a constant molecular weight during purification, so did that from O. sativa leaves during greening of etiolated seedlings, maybe acting as a stable tetramer.

Secondly, in this region, during the process of influencing pedological process and sandstorm activity, the natural course is main, the human factor has just aggravated the natural course to a certain extent, the deterioration of this region s pedological process proved this especially in late Holocene.

二 本区自全新世以来，在影响成壤环境和沙尘暴活动的过程中，自然过程是主要的，人为因素只是在一定程度上加剧了这种自然过程，全新世晚期本区气候环境的恶化更是证明了这一点。

They are most abundant in quartz of pegmatitic leucosomes and granitic rocks, and represent the fluid appearing in their cooling stage. The DL(H2O) of such fluid is 0.93～0.96g/cm3 corresponding to P≈0.6GPa which is compatible with condition when the rapid decompression in this region was ended. 3 CO2-H2O two or three phases inclusions. They are the most widespread, and more frequently in clusters and in intragranular tails in quartz. The relative content of CO2+CH4 and H2O is considerably variable. They are also characterized with lower density (0.6～0.8g/cm3) and low pressure about 0.3～0.4GPa, and may be originated by mixture of carbonic liquid from breaking of most inclusions of peak stage and aqueous liquid of magmatic source. After entrapment, the further decrease of temperature to lower than 330℃ made such fluid separated to two or three phases.
