前言我所自71年开始,承担了研究耐热高分子合成材料的任务。在研究过程中,深感测试合成材料性能仪器缺乏,经常要将样品送到外地有关单位测试,加上路途往返使工作的进度受到了很大的影响。 74年初在北京有关单位帮助下,筹备材料,自装了一台简易的差热——失重联合分析仪,通过对样品的测试,基本上能解决我们测试样品的需要,但仪器多为手动,给测试上带来了不可避免的人为误差,于是在75,76年我们又组装了一台自动示差一失重热
Preface Since 1970, I have assumed the task of studying heat-resistant polymer materials. In the course of the study, the lack of testing equipment for performance testing of synthetic materials often brought samples to relevant units for testing in the field. Coupled with the round trip, the progress of the work was greatly affected. With the help of the relevant units in Beijing at the beginning of 74, a simple differential heat-weight loss analyzer was installed since the sample was tested, which basically solved the need of our test samples. However, most of the instruments were manual, To the test brought the inevitable human error, so in 75,76 we have assembled an automatic differential weight loss test
