But the mixed system of nonionics and polysoap has not synergism. The suspend rate of the mixed system of 6#/3# to number 11,17,19 seed clothing agent can run to 77%,81%,89%,and the rate of viscidit chage is lower than 10%,when the mass fraction ratio of system is 3∶1.

The alkaline consumption of the optimum oil displacement formulation (2 3 formulation),the loss of petroleum sulfonate and the viscosity variation are lower than the values of the literature. It is proved that the pharmaceuticals consumption of this formulation accords with the requirement of oil displacement.

The variation of viscosity can be attributed to a change in the liquid structure, with ion-molecule complexes centered at the ions produced as a result of charge injection from an electrode.

The difference in sound signal absorption in water under unequal conditions is explained by variation of viscosity due to changes in structural state of water, in particular destruction or formation of clusters.

The variation of viscosity when adding Pd(II) suggests the formation of intramolecular loops.

By making use of the empirical relations between stress and strain rate useful expressions concerning the variation of viscosity and activation energies for superplastic deformation are derived.

An extremal variation of viscosity of the LC-CPE/carbon black, silica and talk blends with the filler concentration on both at the flow in a uniform shear stress field and at the capillary flow has been found.

The alkaline consumption of black liquor system to Xinjang outcrop core was studied.The loss of petroleum sulfonate and the viscosity variation were analyzed by the use of the contour diagram method.The result showed that alkaline consumption of the black liquor system was mainly related to the action of alkaline and cores,as well as to the hydrolysis of polyacrylamide.The loss of petroleum sulfonate was mainly related to the adsorption of sulfonate on the core surface.The viscosity variation of the black liquor...

The drawing process of basalt fiber is very important for basalt fiber production. The research on flow and heat transfer in the drawing process makes a contribution to raising basalt fiber quality and strength and avoiding fiber breakage. The numerical model describing heat transfer and flow in the drawing process of basalt fiber production is built. The numerical simulation is made based on the valid simplifications. The geometrical shapes, temperature distribution, velocity distribution and viscosity distribution of fiber cone are given by solving continuity, momentum and energy equations. The results show that fiber cone is a taper and the variation rate of radius of upper fiber cone is bigger than that of middle fiber cone; the shape of fiber cone is related to nozzle diameter and final fiber diameter; fiber formation occurs in the middle cone, in which the variation rate of velocity, temperature and viscosity are the biggest; fiber solidification has relation to cooling condition. The results provide the theoretical basis of choosing and regulating technological parameters in the drawing process.

The auxiliary suspensibility of nonionics in seed clothing agent containing anionics or polysoap as main suspending agent was researched separately. The results show that in the range of experimental temperature the mixed system of nonionics and anionics can generate synergistic effect, and its suspensibility and the change of viscidity compare favorably with the single component. But the mixed system of nonionics and polysoap has not synergism. The suspend rate of the mixed system of 6#/3# to number 11,17,19...
