It is submitted that gross calorific value as air dried basis should be main index in charge,not net calorific value as received basis.
讨论了水分对煤炭质和量的影响 ,指出发电用煤以收到基低位发热量结算存在着不合理性 ,提出应以空气干燥基高位发热量作为主要结算指
In this paper, the ultra-fine grain magnesium alloy was fabricated by magnesium powder-crushing, reactive milling in hydrogen, dehydrogenation and in-situ hot-pressing in vacuum and extrusion.
按“铸态镁合金(AZ31、ZK60)破碎成粉末+纯镁粉末→机械球磨氢化处理→真空脱氢-原位热压制坯→挤压变形致密成形→组织性能分析测试”的工艺路线,制备组织性能优异的超细晶镁合金。
It is suggested that P1 resulted from the stress-induced reorientation of di-vacancies, which consists of the reorientation of neare.
P1峰是由在α和β(或γ)点阵上的空位组成的最近邻双空位偶极子在应力诱导下的重新取向产生的,其弛豫强度随Al含量非单调地变化,在大约25%Al(原子百分比,以下同)处出现最大值。
The reason is that the tempering treatment makes the concentration of supersaturated quenched-in vacancies decrease,and its pining to parent phas.
结果表明,随回火温度升高合金的对数衰减率(δ)逐渐升高,当回火温度达150℃时,δ达到最大值,其原因是回火使过饱和淬火空位浓度降低,对母相的钉扎作用减弱,有利于母相向马氏体相转变,导致合金晶粒内热弹性马氏体数量增多;继续升高温度到200℃,由于新相生成并对马氏体的钉扎,导致合金的对数衰减率下降。
