概要
作者根据自他制造出第一台液塑限仪以来30年的经验，以及他对许多实验室使用和滥用该仪器的观察，得出结论：要精确重复实验结果，需要对仪器设计中的若干细节进行更好的标准化。推荐图1和图2所示的设计作为标准。它保持了已被默认并在许多国家使用了约四分之一个世纪的基本尺寸和底座硬度。在讨论英国标准中因使用硬度差异很大的底座而产生的复杂情况时，作者建议一种可能的解决方案，即基于抗剪强度测量的更合理的试验来替代液塑限试验。

Synopsis From experience during the 30 years since he built the first liquid limit device, and from his observations on the use and abuse of this device in many laboratories, the Author concludes that accurate duplication of results requires improved standardization of several details in its design. The design shown in Figs 1 and 2 is recommended as a standard. It maintains the basic dimensions and hardness of base which have been accepted by tacit agreement and have been in use in many countries for about a quarter of a century. In discussing the complications arising from the use of a substantially different hardness of base in the British Standard, the Author suggests as a possible solution replacement of the liquid limit test by a more rational test based on the measurement of shear strength. D'apres l'experience acquise au tours des 30 ans depuis qu'il construisit le premier appareil a limite de liquidite, et d'apres ses observations sur l'emploi et l'abus d'emploi de cet appareil dans de nombreux la...
