The ideal strength of rock specimen can be determined from its complete stress strain curve.

In this dissertation, the first-principles calculation method based on density function theory is used to study the novel light elements superhard material of BC2N, and determine its physical properties such as structural parameters, electronic bands and ideal strength, as well the effects of high pressures on these physical properties.

Study on semantic priming effects of Chinese word-pairs with different association strength for young and old adults

(2) The responses with higher frequency in the first few positions may not ensure themselves high association strength to the stimuli.

Objective:To explore the characteristics of semantic priming effects and repetition effects of Chinese word-pairs with different association strength by auditory stimulation between young and old adults.

filter) and strong ideal(r.

: In this paper,we discussed the relations of strong ideals,kernel of homomorphisms and con-gruences in a semiring.

This paper discusses the nature of semi-ring absorbable element by the application of semi-ring and lattice theory and achieves some better results in the aspects of semi-ring absorbable element in the semi-ring homology, the strong ideal, the regularity and the lattice theory.
