近代地学研究已进入定量化的阶段,因此,分析样品量剧增,迫切要求寻找高效低耗的分析方法来替代经典方法,但在新的分析方法被确认以前,除了进行标样自检和回收试验等手段检验外,经常还用实际样品与经典方法进行比较测定,根据方法的稳定性,可靠性和适用程度才能作出最后的结论。如为单因子试验,测定数据经常采用t测验法或更简便的统计方法加以判断,但若试验因子较多,简单的t测验法就不能适应或试验效率太低了,复因子试验设计采用方差分析法能在预定机率保证下帮助我们作出较全面而有一定把握的结论。地质样品的熔样和溶液制备是一个较麻烦的过程,传统的碱熔法或酸溶法无论(?)程、设备和耗费等方面都是较复杂而贵重的,而增压酸溶法不仅快速低耗,而且(?)
In recent years, geodesy research has entered a quantitative stage. Therefore, the rapid increase in sample size requires urgent search for a more efficient and cost-effective alternative to classical methods. However, before the new analytical method was confirmed, Test and other means of testing, often with the actual sample and the classic method for comparative determination, according to the method of stability, reliability and extent of application in order to make the final conclusion. In the case of a single factor test, the measurement data is often judged by the t test method or a more simple statistical method. However, if there are many test factors, the simple t test method can not be adapted or the test efficiency is too low. The complex factor test design uses a variance The analytic method can help us to make a more comprehensive and certain conclusion at a predetermined probability. The geological sample melting and solution preparation is a cumbersome process, the traditional alkali melting or acid dissolution method regardless of (?) Cheng, equipment and cost are more complex and expensive, and not only pressurized acid dissolution method not only Fast and low consumption, and (?)
