1 A support material with low expansivity and high conductivity, called DG alloy, was prepared by powder metallurgy. The effects of sintering process on its properties and microstructure were studied.

2 Interface expansivity how much?

3 The main technological properties are linear expansivity, tensile strength, flowability and solidification time.

4 The research of this system has greatly developed the universality and expansivity of the test system, and realized the intelligent automatic test of the control system of missile.

5 In this paper, dealt with are the different effects of the superfine slag on the shrinkage and expansivity of the high strength concrete (HSC) and the shrinkage-compensating concrete.

6 On the assumption that the product of volume thermal expansivity and bulk modulus based on the thermodynamic approximation theory, a new equation is presented for volume thermal expansion coefficient.

7 For each test series the samples were maintained according to its own maintaining method and the loss rate of quantity or length expansivity was measured in defined period.

8 In this article, the method of producing the glass from the goldmine-tails has been studied, and the bending strength, chemical stability, density, thermal expansivity of the glass have been measured.

9 The practical value of knowledge resources possesses popularity , duality of exhaustiveness and non exhaustiveness, and expansivity.

10 For foundry sand from a famous domestic area, the curve of thermal expansivity with the temperature was described.
