in particular for sorting a mixture of non-metal parts and non-ferrous metal parts, using a chute which receives the mixture and is inclined in the conveying direction, in which the chute has a ski-jump-like outlet, the valuable non-ferrous metals, in particular aluminium, can be separated...
15. A non-noble metal oxygen reduction reaction catalyst labeled as Co-C-N(800) was synthesized by heat-treating a mixture of urea, cobalt chloride and acetylene black for 2 hours at 800℃ in an inert nitrogen atmosphere. 机械研磨尿素、氯化钴、乙炔黑混合物并经800℃高温热处理后,制备出了非...
thicknesses, deniers, fibrillations, cross-sections or aspect ratios, prior to their addition to the concrete, so as to accommodate the mortar factions within proportioned concrete containing graded aggregate, provide a continuous distribution of fibers therein and thereby inhibit the initiation of ...
The phase transition between bcc and hcp is called the martensitic transition, during which crystallographic relationships are observed between the two phases. Shear softening associated with the martensitic transition of a bcc structure to its hcp counterpart has been reported in several metal alloys29...
The molten weld metal is used in joining one non-ferrous metal piece with at least one other metal piece. The process and exothermic reaction mixture have distinct advantages over the prior art. These advantages include a higher filler metal yield, reduction of odor, and a higher quality ...
Alloys- mixtures in which the main element (or, usually, elements) are metal(s). A more technical definition of an alloy is 'a partial or complete solid solution of one or more elements in a metallic matrix'. Common examples of alloys include bronze, brass and steels. When alloys are sp...

PURPOSE:To produce an ingot free from non-metallic inclusion and having little macro-streak flaw by constituting an exothermic heat insulating board for feeder head used at the time of casting the steel ingot so that the calorific value ... N Hiroya,S Kazuya 被引量: 0发表: 1991年 Influence...
1. Experiments were performed to determine whether the specific collagenases and other metal proteinases are bound and inhibited by alpha(2)-macroglobulin, as are endopeptidases of other classes. 2. A specific collagenase from rabbit syn... Z Werb,MC Burleigh,AJ Barrett,... - 《Biochemical Jou...
Deracemization is a term used to describe a process in which a racemate is converted into a nonracemic product in a 100% theoretical yield without intermediate separation of materials.
