carbon grain
2.Study was done according to the species of shells, carbon 14 age-dating, and sediment grain size. It is shown that the ancient coastline 1 510a ago was higher about 1m than the modern one, and recent aeolian sands had been activating since Sui-Tang dynasty, and have been being a hidden trouble till now.
8.High speed cooking mixer is one of necessary equipments for processing plastic, which is used for mixing PVC, polyethylene, polypropylene, grain painting, desiccation of moisture absorption colophony product, desulfurization of reclaimed rubber, asbestos product, electrical carbon, amino powder, flame retardant, dope, pharmacy, coal and daily chemical products and so forth.
9.Based on the theory of deformation enhanced ferritic transformation(DEFT),the effects of process parameters,i. e. deformation temperature,strain rate and prior austenite grain size, on the microstructural evolution,transformation kinetics and the critical strain (ε_c) for the completion of DEFT were investigated during deformation of undercooled austenite in a low carbon steel.
10.The notice requires all localities departments of Quality and Technical Supervision must immediately arrange for food processed products in alterative grain, waste oils in the edible oils, dairy products of animal protein hydrolysate, soda consumption level of carbon dioxide and Africa, the Central African edible soy protein hydrolysate, peppery products in Sudan, 17 kinds of possible existence of non-food raw materials illegal conduct special inspection of the scene production enterprises.
