美国新型聚合物系统公司R.Dyer说,测试程序的精度是每个人关心的问题。在许多实验和工业过程中,引起误差的最主要原因是缺少精确而可重复的仪器标准化技术。据说,只有极少数材料可以作为光学参考标准,按照定义,这种材料必须是准确、可重复测量和可复制的,并应价格合理且易于使用和稳定。 R.Dyer, a new polymer systems company based in the United States, said that the accuracy of the test procedures is something everyone is concerned about. In many experiments and industrial processes, the primary cause of errors is the lack of accurate and repeatable instrument standardization techniques. It is said that only a very small number of materials can serve as an optical reference standard, which by definition must be accurate, repeatable and reproducible and should be reasonably priced and easy to use and stable.
