查询词典 by air

Its thermodynamic characteristic is gimilar to R410A. Contrast experiments by air enthalpy difference method are performed. Experimental results indicate that without modification to system components, cycle performances of M3 are close to R410A. Its cooling capacity is slightly smaller than R410A. It has a greater COP and low power consumpt...

在标准的空气焓差实验台上对M3、R410A进行了对比实验，实验结果表明，在不改动系统部件的情况下，新工质M3可保证R410A系统的循环性能基本无大的变化，其循环性能接近R410A，制冷量稍小，但COP值大，耗功少，具有替代新系统中R410A的潜力。

A method for the determination of ferrum content in cobalt based alloy dust by Air-C 2 H 2 flame atomic absorption spectrophotometry was set up.

建立了一种用空气-乙炔火焰原子吸收法测定钴基合金喷粉中铁含量的分析方法，探讨了硅对铁测定的干扰机理，对用氯化钙作为硅干扰铁测定的释放剂进行了试验。

The oxidant 〓 plays indirect role in dissolving gold, and mainly controls the mix potential of Au in the alkaline thiourea solution. In which the "mix potential"is the decisive factor affecting the dissolution of gold. The reaction driving force is enough to have formamidine disulfide oxidize Au to Au〓 at the potential of about 0.4V. And then thiourea molecular complexes with Au〓 ion soon, which causes the fast dissolution of gold in the alkaline thiourea media. The dissolved weight of gold in 0.25 M thiourea solution with 0.05M Na〓SO〓 and 0.1M 〓 of pH 12. 5 by air at the temperature of 303K is 7. 8mg·cm〓 within 1hr.

在碱性硫脲溶金过程不起直接作用，而是通过S〓O〓来控制二硫甲脒有效形成的金在溶液中的混合电位；&混合电位&是影响碱性硫脲溶液溶金与否的决定性因素，在0.4V左右，有足够的推动力致使二硫甲脒氧化Au成Au〓，随后硫脲与Au〓络合形成稳定的络离子Au〓，从而使金快速溶解；温度为303K、pH为12.5时，在含0.05MNa〓SO〓、0.1M 〓及0.25M硫脲的溶液中，鼓入空气，金的溶解量在1hr内为7.8mg·cm〓；铜只有微量溶解，银、镍、铁则几乎不溶解。
