1)  thermal volatilization residual sample stage
净化阶段
2)  purification section
净化段
3)  purification section
净化工段
1.
The trial production of SA from pyrite with high arsenic-containing content[w(As)1% or 2% ~ 3%]is introduced,the arsenic is roasted into arsenic oxide whose solubility in acid is lowered with decreasing temperature,and it is removed as solid at purification section.
沸腾焙烧砷变为砷的氧化物,其在稀酸中的溶解度随温度降低而减小,在净化工段砷以固态析出而被除去。
4)  evolution stage
演化阶段
1.
Division of seal evolution stages of shale caprocks to gas in each phase and its research significance;
泥岩盖层对各种相态天然气封闭性演化阶段划分及意义
2.
The beginning and release depth of mudstone overpressure in different evolution stages and its implication;
泥岩超压不同演化阶段开始及释放深度规律及其研究意义
3.
Characters of corn hybrid population growth types at IV evolution stage and its evolution characters and trend in Hebei-Shandong-Henan summer corn plantiug zone were analyzed in this paper.
运用群体生育型特征与演化的观点,分析了冀、鲁、豫夏玉米区玉米杂交种群体生育型演化进程至端的第Ⅳ演化阶段群体生育型基本特征与演化特征及其演进趋向,结果表明,第Ⅳ演化阶段群体生育型基本特征表现为株型紧凑或半紧凑,穗位叶适中,雄穗分枝较少,抗倒性和抗斑性优良,籽粒长,出籽率高;其演化特征主要由穗粒结构与第一叶面积、生育日数决定,其穗长演化将趋于稳态,穗行数、穗粗、百粒重、行粒数与第一叶面积、株高将呈现较明显的持续演进态势,其中生育日数、行粒数和株高将分别向早熟、多粒和高棵方向回归。
5)  mineralization stage
矿化阶段
1.
Based on EPMA analysis of arsenopyrite and the phase diagram of coexisting minerals pyrite-arsenopyrite,we conclud that temperature of the main mineralization stage is stable within 300~450℃.
本文通过主要矿化阶段热液矿物毒砂成分的测定,利用相图中共生金属硫化物稳定温度范围得出主要矿化阶段的温度为300~450℃,它比通过石英流体包裹体测得的均一温度更准确地代表成矿流体的温度,由此温度平均值计算出的氢氢同位素能准确判断初始流体的来源。
6)  micro stage
微阶段化
补充资料:净化阶段
分子式:
CAS号:

性质: 石墨炉原子吸收分析程序升温中的清除阶段或称热除残阶段(thermal volatilization residual sample stage)。它是在试样原子化以后,以更高的温度将石墨管中所遗留的试样挥发清除,以保证下一次测定不受影响,即不会有记忆效应。
