The preparation of nanometer copper powders by using NaH_2PO_2 as reductant;

Preparation of silver-plated copper powder and its properties;

Research on copper powder conductive acrylate press-sensitive adhesive;

5It was studied that the formation,structure and properities of the solid solution sintered from Cu powder and Ni powder using the method similar to powder metallurgy.

It is also showed that,by the second warm compaction,the monophase Cu-Ni solid solution is easier,Cu powder and Ni powder sinter has higher density and hard.

A tentative technique of preparing nanon Cu powder with CuSO 4 and NaH 2PO 2 as main raw materials was proposed.

Three beef calltles of similar body weight with permanent rumen fistulae were used in this experiment to study the effect of different ratio of nitrogen to sulfur and copper on rumen pH、concentration of ammonia-n and plasma copper.

The effects of SDBC to substitute blood meal on growth performance of weaned piglets;

Studies on Amino Acid Digestibility of Fermented Blood Mealand Cooked Blood Meal in Caecetomized Cockerel;

The hydrolysis methods for porcine blood meal by neutral protease have been studied.

The principle of the influence of parameters of extrusion system, including the diameter of the Die diameter, the Screw speed, the Screw pitch, Moisture content on the NSI of the blood meals was discussed in this paper.

Blood meals are better animal albumen fodder, development and utilization; blood meals alleviate animal albumen fodder in short issue not merely, and protect the environment.
