Study on technology of extracting silver from waste fixing bath by replacement method;

The text give some measures to prevent freeze bulge on road such as: replacement method, insulate temperature method and tranquilization transact measure.

In this article, hydrogen is adopted to displace the ideal gas in the experiment of "measuring the Molar gas constant R by displacement method" and a corresponding calculator program is designed.

A new microscale experimental plan for determination of molar gas constant by displacement method had been presented.

Via introducing of F-ions,a kind of core-shell Fe/Al nanocomposite had been prepared by displacement method,in which the micron Al grain were coated in a lay of nanometer Fe particles.

In the paper,the relationship between deflection curves of various kinds of beams and cantilever beam is introduced;the displacement equation of the conversion methods for resolving beams are given,including the equation of slope rotation angle and the equation of deflection.

The principle of the conversion method for solving the displacements of beams is given.

It presents the equation of slope rotation angle by the conversion method and the continuity relationship of slope rotation angles by the principle of conversion.

This paper involves in the preparation of Cu Ag bimetallic powders with dendritic and hexagonal morphologies by replacement method at the exist of macromolecule dispersant.

This article mainly introduces the whole process of solving the problems of replacement the Spanning tree.

As to produce nitromethane there were mainly gas phase nitrofication and substitution method with nitrite; and for nitroethane there were nitroficating low carbon alkane, chloroethane, and diethyl sulfate; as for 1 nitropropane usually nitroification of propane and propene was used; and the direct o.
