Firstly,data of total flow rate and water holdup etc.

Application of these 10 characteristic indexes which describe features of the two-phase flow as the inputs of a RBF neural network results in an excellent prediction of water holdup of the two-phase flow within flow rate ranges of.

In the cause of development of oil field, the produced fluids profile of oil pump well usually adopts through-liquid packer-type to measure the quantity of oil and water reservoir, but the sensitivity of high water response is very low , for the water holdup tool of through-liquid is always limited by ability of capacitance in logging high water well.

By the methods of field survey and soaking extraction,the storage,water-holding capacity,water-holding rate,and water-absorption rate of the litters in Larix principis-ruprechtii,Larix kaempferi,Picea asperate,and Picea abies plantations in west Qinling Mountains were studied.

Based on twenty-two varieties of flour from Kunming market in Yunnan province,tested wet gluten content,dry gluten content,gluten moisture absorption and extensibility by using hand-washing,to study on the relationship between gluten moisture absorption and extensibility by using correlate analysis,path analysis and multiple regression analysis.
