As an orthodox technology, combination of gravitational separation and coalescence technology advances coalescence efficiency largely.

Gas accumulation efficiency and its main controlling factors in China's large and medium gas fields;

Reservoiring process and accumulation efficiency of Feixianguan Formation gas pool in Luojiazhai,northeastern Sichuan basin;

In this paper, gas accumulation efficiency was defined and calculated in terms of gas reserves, gas-bearing areas and accumulation periods.

In the electrolyze and decompose process of sodium aluminate solution with ion membrane,some key influence factors on agglomerative efficiency were researched.

With the help of the analysis and of an elec trical aggregation efficiency equation deduced from reasonable hypotheses,the in fluence of three main factors in electrical aggregation,namely the urrent intens ity,operation time and the organic compound concentration in the wastewater,on t he aggregation efficiency has been discussed.

A BP neural network and a RBF neural network models are developed to predict the polymerization efficiency for PDPhSM matrix nanocomposite thin film respectively.

we use RBF neural networks to construct a model of laser-ablation conditions and polymerization efficiency,and then use this model to establish the nonlinear relationship between technology parameters(laser fluence,ambient pressure,distance between target and substrate,deposition time) and polymerization efficiency.
