experimental data(① From a reassessment of all the available experimental data, it was concluded that CaO and MgO components of the slag, had the strongest effect on the phosphate capacity of the slag. 依据对所有现存试验数据的再次研究，得出的结论是：炉渣中 CaO 和 MgO 组分对炉渣的磷酸盐容量影响最大。 ②In a recent study of the available experimental data on steel-slag reactions, it became evident that the equilibrium constants of slag-metal reactions vary with the slag composition. 在对钢-渣反应现有实验数据的最近一次研究中，已经明确了渣-金反应的平衡常数随炉渣成分发生变化。)
justification for rejection of steel tube(Where light tubes approach the low limit of outside diameter, some 'black' threads (perfect at the root and imperfect at the crest) are to be expected beyond the gauge plane, but such 'black' threads shall not be regarded as justification for the rejection of the tubes. 薄壁管的外径接近下限值时，会有一些超过基准面的"黑皮"螺纹(根部完整，顶尖不完整)，但这些"黑皮"螺纹不能作为钢管判废的依据。)
