硅酸盐岩石經典分析方法的建立差不多已有一个多世紀的时间。其间經过很多人的改进,在本世紀初期,方法基本上已經定型,很少再有重大的变动。經典方法分析时間冗长,这一点是历来大家所公认的,然而对其精密度和准确度看法上,則分歧很多。迄今为止,仍有人认为,在准确度上还沒有其他方法超过經典方法,且一般的快速方法,往往有其貭量与速度之间不可克服的矛盾,两者不可得兼,須权衡輕重,决定取舍。其实經典方法无論从精密度或准确度来說,都不是不可非議的。誠然,分析者在操作上有熟练的技巧,一般是能得到重現性良好的結果,但有些元素测定的偶然誤差仍旧不小。至于硅和鋁的測定方法不够完善,則早已众所周知了。最近几年,硅酸盐岩石的快速分析方法,在利用了
The classic method of analyzing silicate rocks has been established for more than a century. In the meantime, after many people’s improvements, methods have basically been finalized in the early part of this century, with few major changes. It has always been recognized by all of us that time-consuming analysis of classical methods has led to many differences in terms of their precision and accuracy. To date, there are still some people who think that there is no other method beyond the classical method in accuracy and that the general rapid method often has its insurmountable contradiction between quantity and speed. Both of them are not available and must be weighed down to decide Choose. In fact, the classic method in terms of precision or accuracy, are not indisputable. Admittedly, analysts are skilled at manipulating the data and generally have good reproducibility, but the occasional error of some elemental determinations is still small. As for the determination of silicon and aluminum is not perfect, it is already well known. In recent years, rapid analysis methods of silicate rocks have been utilized
