| 释义 | beryllium noun[ U ] uk /bəˈrɪl.i.əm/ us /bəˈrɪl.i.əm/(symbolBe) a chemical element that is a hard, light, silver-grey metal, used to make strong alloys (= mixtures of metals)铍（一种银灰色金属元素，坚硬质轻，用于制作合金） Chemical elements actinium alkali metal americium antimony astatine berkelium brimstone calcium fluorine germanium lithium manganese nickel plutonium quicksilver selenium silicon sodium sulphur transition metal The volcanoes we shot three months ago yielded a fine flow of lava with all sorts of metals—nickel, beryllium, vanadium, chromium, iridium, as well as copper and iron. There are considerable deposits of beryllium, and they occur in high concentration in its ores. beryllium | American Dictionaryberyllium noun[ U ] us/bəˈrɪl·i·əm/ chemistry a hard, light, gray chemical element that is a metal and is used to make strong alloys (= mixtures of metals) Examples of berylliumberyllium We can overcoat these thermally stable mandrels with plasma polymer, vapor deposited polyimide, or sputtered beryllium with unparalleled wall thickness and composition control. To this end, we have designed plastic ablator capsules which are easier to fabricate and fill than beryllium capsules. The rapid viscosity decrease and rather small hydrogen diffusion coefficient at glass transition temperature result in "foaming" of beryllium hydride in the course of thermolysis. Investigation of deuterium permeability of sputtered beryllium and graded copper-doped beryllium shells. At this stage, a few beryllium shells with graded dopants were made but research on surface finish and characterization of the dopant levels is ongoing. Organic matter formed from hydrolysis of metal carbides the bombardment was converted partially into beryllium carbide, which we have discussed in the preceding paragraph. Note that the capsule used in the integrated calculations is the beryllium ablator capsule. The beryllium designs could be subject to perturbations seeded by the movement of the first shock across the ablator consisting of material with finite grain size. Carbon synthesis occurs via a reaction in which two alpha particles unite to form a beryllium nucleus that then combines with another alpha particle to form carbon. Nobody knows why so few people are sensitive to beryllium; yet it is so. From the Hansard archive Example from the Hansard archive.
