The paper introduces intension, function and existent major question of supervisal monitoring, advances essential important document and program important document that is 2 guarantee condition of supervisal monitoring work, suggests how to bring into play function of supervisal monitoring work for environment protection aftertime.

The best conservation condition of volatile phenol samples is discussed by the orthogonal testing method.

The conservation conditions of the reservoirs are controlled by the fault sealing ability.

Making use of the geochemical data of saturated and aromatic hydrocarbons from 9 water samples (including 8 drilling well formation water and 1 fountain water ), combined with the general analysis on formation water (abiochemistry and isotopes of δD\δ~(18)O), we discuss the different conservation condition in the two areas.

Storage condition:①dry condition,②moisture condition,③room temperature(25 - 27℃ .

Storage condition of the irradiated femora samples was studied.

According to the storage time of hatching eggs(1～3 d,4～6 d,7～9 d,10～12 d),the ways of placement(the small head of eggs upwards or downwards),and whether turned eggs over or not,hatching eggs were divided into 16treatments to detect the effect of storage condition on hatchability.

The culture temperature and storage conditions of 14 high-temperature monascus strains separated from high-temperature Daqu in Langjiu Distillery were studied.
