本文对橡胶的力学、热学、光学、电学等16个基本物理常数的取值进行了评述。每一个看来最可靠的常数的值都已标明，必要时，已按标准大气压力和25 ℃的温度条件进行了校正。给出了四种不同形式的橡胶的值：纯化烃、商业生胶、含2%结合硫的软硫化橡胶和含32%硫的硬橡胶。调查表明，目前对橡胶基本特性的认识存在重大差距。在某些情况下缺乏数据，而在许多其他情况下，现有的最佳值并不具有当今科学和工业工作所需的准确性。因此，本文件不仅可以作为不同常数的选定值的摘要，而且可以作为规划未来调查的基础。
Abstract A critical survey has been made of the values of 16 basic physical constants of rubber in the fields of mechanics, heat, optics and electricity. The value for each constant which seems most reliable has been indicated and, when necessary, has been corrected to the standard conditions of normal atmospheric pressure and a temperature of 25° C. The values have been given for rubber in four different forms: purified hydrocarbon, commercial raw rubber, soft vulcanized rubber containing 2% combined sulfur and hard rubber containing 32% sulfur. The survey indicates that there are significant gaps in present knowledge of the fundamental properties of rubber. In some cases data are lacking, while in many others the best values available are not of the accuracy required for present-day scientific and industrial work. This paper may therefore serve not only as a summary of selected values of the different constants, but also as a basis for the planning of future investigations.
