摘要:

In a paper published in the JOURNAL OFRHEOLOGYSheppard and Houck showed that certain solvent combinations of non‐polar and polar liquids produced solutions of cellulose esters which gave purely viscous flow. It was argued that this indicated that the dispersion of these substances had been carried to molecular dispersion, the crystallites indicated by x‐ray examinations being reduced to molecular entities of the long chain, primary valence type.

摘要:

The study of egg albumin has been approached from different angles and a large amount of work has been done upon it. Sorensen (1917) in a classical series of papers has studied the methods of preparation, chemical composition, chemical and physical‐chemical properties of albumin isolated from egg white.

摘要:

Since little is known concerning the laws of plastic flow, it is often convenient to use approximate methods of calculation based on the law of Poiseuille for simple viscous liquids. Neglecting the kinetic energy correction, the reciprocal of the viscosity isFluidity = 4qπR3PR2L = YX(1)whereq= rate of flow in cm3per secondP= pressure causing flowRandL= radius and length of capillary

摘要:

In 1678, roughly two hundred and fifty years ago, Robert Hooke announced his justly famous law of deformation, “Ut tensio sic vis” or the deformation of a body is proportional to the shearing stress producing it, or finally, in the more elegant language of mathematics,s = eFr.
