aall types of metal are detected. However, magnetic metals are detected more reliably than non-magnetic ones. This way of measuring also makes it possible to detect metal particles inside the product or in non-metal packaging. The examined products are not harmed or changed in any way. 金属...
In general the metal simple substance has the metallic luster, the majority metals are the silver-white colors; The nonmetallic simple substance does not have the metallic luster, the color also is generally many and varied.[translate]
aThe understanding ofthe magnetic and electronic propertiesof binary magnetic metallic alloys forms a wide field of research. The study of these systems is interesting not only from a fundamental point but also from a practical point. Among the alloys of the ferromagnetic 3d transition metals and ...
Magnets attract some types of metals, but they can also push other magnets away. So how come you feel only the pull of gravity? In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all o...
16.All metals are corrodible under the proper circumstances. 所有金属在一定情况下都是可腐蚀的。 17.The design of the rocket nozzle also has much to do with the behavior of the exhaust and the resulting velocity of the vehicle itself. 火箭喷管的设计与排气的性能及飞行器本身的有效速度有很大关系...
the bottoms are enclosed in two capsules esferico-conics, sealed with plugs diving, while the magnet superior, is locked in a capsule formed by threaded two parts which serves to unite two rods determining the perimeter of collar total all made in noble metals and have attached on its lowest...

When performing an electrostatics analysis, any conducting materials (typically metals) are first removed from the analysis and the metallic surfaces are seen as exterior boundaries from the perspective of the dielectric materials. Steady Currents: This analysis is used to compute the steady current ...
摘要: Non-evaporable getter alloys containing zirconium, vanadium, iron, manganese and one or more elements selected among yttrium, lanthanum and Rare Earths are described, having improved features of gas sorption, particularly of nitrogen, with respect to the known getter alloys....
