一、 General Properties 1.硼的化学性质与Si有某些相似之处(对角线相似原则),通常硼呈现+3氧化态,负氧 化态的情况很少。硼与金属形成非化学计量的化合物( nonstoichiometric compounds), M4B、M2B、MB、M3B4、MB2、MB6等

Processes: gift of Slo2-Expose Si to steam = uniform insulating layer or metal film growth: high vacuum, single element Contrast with CVD: toxic, corrosive gas flowing through valves

1984年2月27日,我国国务院颁布实行以国际 单位制(SI)为基础的法定单位制

She was trying to get to the hospital, but there was a bad traffic jam S10. the baby waited to \arrive until we got to the hospital

Plant nutrients Plant growth requires various nutrients Major nutrient elements: C,N, P trace elements: S, Si, Cl, I, and metallic elements(Fe, Mn, Cu, etc) The minor elements because of the low demand can Water y be supplied at adequate rates in natural

Information in Competitive Markets In purely competitive markets all agents are fully informed about traded commodities and other aspects of the market. What about markets for medical services, or insurance, or used cars?

Dictionary A chemical-shift reference is used to define the (CH3)4SI positions of the resonances in the spectrum in terms of parts-per-million, or ppm, of frequency It is a material which is often directly added to the

Thus, to find Nash equilibria in IN=N, A(Si)), uin, we use the conditions: for ach player i (1)he is indifferent among all strategies in St,and (2)any strategy in St is at least as good as any strategy in S Example 3.7.(Meeting in an Airport ). Mr Wang and Ms Yang are to meet in an irport. However, they do not know whether they are to meet at door a or door B. The payoffs are specified in the following
