首先，本文对团聚体的拉伸强度进行了回顾；即讨论了最重要的理论考虑因素、各种测量方法、通过实验结果对测量技术进行了比较，并简要介绍了单向载荷下的变形行为。第二部分讨论了新的进展。对于在接触点传递力的团聚体的拉伸强度，显示了一种新的关系，其中考虑了各个力引起的位移。不仅测量拉伸强度而且测量力分布的实验证明了当存在短程力时采用新方法的必要性。然而，当长程力（例如由于合适的大型液桥而产生的力）作用时，不需要考虑吸引力的力-位移特性。然后吸引力可以线性叠加。详细讨论了附聚物的拉伸强度的测量。特别指出了使用分流板装置进行测量时存在的问题，并提出了一种解释结果的新方法。通过对比实验验证了该方法的适用性。
Firstly, this paper gives a review of tensile strength of agglomerates;i.e.a discussion of the most important theoretical considerations, the various methods of measurement, a comparison of measuring techniques by experimental results and a brief look at deformation behaviour under unidirectional loading. In the second part new developments are dealt with.For the tensile strength of agglomerates in which forces are transmitted at points of contact, a new relationship is shown in which the displacements due to individual forces are taken into consideration. Experiments in which not only the tensile strength but also the force distribution are measured demonstrate the necessity of the new approach when short-range forces are present. However, the force—displacement characteristics of the attractive forces need not to be taken into account when long-range forces —e.gforces due to suitability large liquid bridges — act. The attractive forces may then be linearly superposed.The measurement of the tensile strength of agglomerates is discussed in detail. In particular the problematic nature of measurements using the split plate apparatus is pointed out, and a new method of interpreting results is suggested. The applicability of this method is tested by comparable experiments.
