The effects of temperature and applied stress on rupture life, and the relations of temperature, applied stress and rupture life to characteristic dimensions of coherent phases (γ matrix channel width and rafted γ precipitate thickness), and to the elongation as well as to the cross sectional area reduction of the tested specimens were investigated.

The P92 steel is a steel sort being used for main steam pipelines of ultra-supercritical units at present,its creep rupture life has widely drawn close attention.

The chemical and physical properties of the feather fiber were evaluated with weight loss,breaking strength and breaking elongation.

Addition of the kind will help improve ammonia fibre's breaking strength and breaking elongation,and prohibit yellowing of its thread.

Influence of polypropylene tow fiber on hardness, weight, circumference, sucking resistant index of filter stick and finished filter stick rate was discussed under different breaking tenacity and breaking elongation.

It showed that the breaking length and burst index of two pulps were higher than those of an American hardwood pulp,and the strength properties of E.

The paper analyzes the interaction between woven fabric and needle in the integrated piercing process of orthogonal laminated woven fabrics, proposes and establishes fiber bending elongation and elongation breakage model,and talks over the structure parameters influencing fiber bending elongation.

By analyzing in the regards such as maturing coefficient, average single fiber breaking strength, breaking length and Micron Value of cotton from different growing areas in China, and conducting boiling and blea.

Determination of the breaking length of ice sheet against iceresist structures is one of the basic problems for the analysis on dynamic load and iceenvironment conditions of offshore structures.
