The states of heat transfer in a four-stroke turbocharged loco- motive diesel engine are discussed here. Several new formulas of overall coefficient of heat transfer have been used to compute the rate of heat transfer in locomotive diesel engines. And the resu- lts of computation are compared with the conclusion of the tests. By the way, the states of heat transfer in diesel engines under different temperatures of cylinder wall are also discussed here. And we can draw the conclusion on how different temperatures...

The new fire assay is studied with antimony as a collector for enriching gold at ng/g levels. The method involves the collection of gold in molten antimony when the sample is fused at 950℃ with a flux containing antimony oxide, sodium carbonate, potassium carbonate, borax, bismuth oxide, and flour, and the cupellation of the resulting antimony alloy to obtaint an assay bead(Ag bead or Ag—Pd bead)containing the gold. The results show that the enrichment of gold with antimony assay is superior or equal to that...

The new fire assay is studied with antimony as a collector for enriching gold at ng/g levels. The method involves the collection of gold in molten antimony when the sample is fused at 950℃ with a flux containing antimony oxide, sodium carbonate, potassium carbonate, borax, bismuth oxide, and flour, and the cupellation of the resulting antimony alloy to obtaint an assay bead(Ag bead or Ag—Pd bead)containing the gold. The results show that the enrichment of gold with antimony assay is superior or equal to that with lead assay, where as the reagent blank is much lower. The determination of gold in the assay beads can be accomplished by both emission spectrometry(ES)or graphite furnace atomic absorption spectrometry(AAS). The detection limit of the two methods is 0. 1 ng/g. Analytical blank is 0. 7±0. 3 ng. The overall coefficient of variation for 3. 4 ng/g with ES is 10%, with AAS is 3. 7%. The methods mentioned above are rapid and applicable to the determination of gold in 6 reference materials with satisfactory results.

研究了用锑作捕集剂富集地质物料中ng/g级金的新火试金法。此法分为捕集和灰吹两部分。当样品同含有氧化锑、碳酸钠、碳酸钾、硼砂、氧化铋和面粉的熔剂在950℃熔融时,金被捕集在熔融的锑中。然后灰吹此锑合金而得到含金的试金合粒(Ag粒或Ag-Pd粒)。结果表明,对于金的富集,锑试金法优于或等于铅试金,而试剂空白则低得多。试金合粒中金的测定可用发射光谱法(ES)或石墨炉原子吸收光谱法(AAN)完成。此两法的检出限都是0.1ng/g,分析空白0.7±0.3ng。对于3.4ng/g的样品,全过程的相对标准偏差,用ES法为10%,用AAN法是3.7%。上述方法快速,用于6个标准物质的测定,结果满意。
