The task of this chapter is to explain the sense in which molecular theory—both molecular-kinetic theory and chemical-molecular theory—were still viewed as hypotheses as of 1900 and why the evidence bearing on them during the second half of the nineteenth century was insufficient for them to have achieved standing beyond this. The chapter reviews the strengths and limitations of the evidence in question, taking advantage of two widely read textbooks in physical chemistry published in the 1890s by Wilhelm Ostwald and Walther Nernst and a uniquely comprehensive review of the evidence pertaining to the kinetic theory of gases, by O. E. Meyer, published in 1899. This background defines the historical context within physics and chemistry for the developments covered in the remainder of the monograph.

PPTA fibers made by China ShenMa Group Co., Ltd and Kevlar49 fibers made by Dupont as experimental materials were used in this paper. The differences of molecule structures were contrasted through infrared spectrum and degree of polymerization-counting by the detections of viscosity. The PPTA fibers were put into distilled water and seawater made by ourselves respectively, then ultrasonication were used to deal with them. After this, using the SEM to observe, found that the cracks appear on the fibers surfaces, presented the fibrillation and plush-like microfine fibers. Meanwhile the strength weak-link increased and breaking strength and elongation at break of fibers lowered after ultrasonication. Molecular kinetic theory was used in this paper to study loss of fibers the mechanical property.
