Summary1.We have proposed a one step method for preparing 1,3-disilicacyclobutanes from chloromethyl chlorosilanes and magnesium in ether.2.This method is general and permits preparation of previously unknown 1,3-disilicacyclobutanes with functional groups on the silicon atom. 出版机构:Springer US 刊物名称:Russian Chemical Bulletin 出版时间:1965 ISSN:1066-5285 数据源:报刊文摘
Summary1.The alloying of WC-TiC-Co alloys with tantalum carbide increases their bending strength (at moderated temperatures), hardness (at high temperatures), thermal cycling resistance, and oxidation resistance.2. 出版机构:Springer US 刊物名称:Powder Metallurgy and Metal Ceramics 出版时间:1965 ISSN:1068-1302 数据源:报刊文摘
Conclusions1.The interaction of hexafluoroacetone imine, as well as that of hexafluoroacetone and nitroperfluoroacetone, with butadiene and isobutylene was studied.2. 出版机构:Springer US 刊物名称:Russian Chemical Bulletin 出版时间:1965 ISSN:1066-5285 数据源:报刊文摘
Summary1.An investigation was made of the phase composition and homogeneity ofreduced powders of stainless steels Kh30, Kh17N2, Kh23N18, 1Kh18N9T, and OKh18N9. The surface layers of chromium-nickel steel powders contain oxides, including spinel type phases.2. 出版机构:Springer US 刊物名称:Powder Metallurgy and Metal Ceramics 出版时间:1965 ISSN:1068-1302 数据源:报刊文摘
SummaryThe abrasive capacity of carbides and borides of titanium, zirconium, hafnium, vanadium, chromium, tantalum, molybdenum, and tungsten was investigated. 出版机构:Springer US 刊物名称:Powder Metallurgy and Metal Ceramics 出版时间:1965 ISSN:1068-1302 数据源:报刊文摘
SummaryA study was made of the sintering of niobium carbide in electric furnaces. It is shown that niobium carbide parts can be sintered at relatively low temperatures (2400–2500°C) if activating additions are used. 出版机构:Springer US 刊物名称:Powder Metallurgy and Metal Ceramics 出版时间:1965 ISSN:1068-1302 数据源:报刊文摘
Expressions are also obtained for the distribution of the electric potential associated with the above-mentioned temperature redistribution. 出版机构:Springer US 刊物名称:Atomic Energy 出版时间:1965 ISSN:1063-4258 数据源:报刊文摘
Geologic cross sections are either general or specific. A general cross section is an abstract view of an area drawn along an imaginary line, and a specific section shows part of an area along a definite line. 出版机构:University of Chicago 刊物名称:The Journal of Geology 出版时间:1965 ISSN:0022-1376 数据源:报刊文摘
AbstractResults are given of an experimental investigation of the thermal relaxation time of particles in a fluidized bed. Values of the coefficient of heat transfer from particles to gas are determined. 出版机构:Springer US 刊物名称:Journal of Engineering Physics and Thermophysics 出版时间:1965 ISSN:1062-0125 数据源:报刊文摘
AbstractNew relationships are presented which describe the temperature and humidity of the medium at the edges of the boundary layer in heat and mass transfer processes. 出版机构:Springer US 刊物名称:Journal of Engineering Physics and Thermophysics 出版时间:1965 ISSN:1062-0125 数据源:报刊文摘
