双立杆式(CJS—42型)高温弹性模量测定仪系国内首次研制成功的一种新型高温弹性模量测定装置。本文介绍了该仪器指标、工作原理及测定误差的分析计算、实测数据及国内外对比等。弹性模量是材料的最基本的物理量,通用的设备是悬丝法,但它使用有一定的局限性,特别是对于一些特殊材料及特定场合使用极为不便。本文对新型测定仪的一系列独特的优点作了较详细的说明。
Double pole (CJS-42 type) high temperature elastic modulus tester is the first successful development of a new type of high temperature elastic modulus measurement device. This article describes the instrument indicators, the working principle and determination of error analysis and calculation, measured data and comparison at home and abroad. Elastic modulus is the material of the most basic physical quantities, the general equipment is the suspension wire method, but its use has some limitations, especially for some special materials and the use of a particular occasion is extremely inconvenient. This article gives a more detailed explanation of a series of unique advantages of the new analyzer.
