The numerical results for semiconductor heteroj unctions consisting of III-V group show that the contribution from 10 phonons with higher frequency can not be neglected in weak field limit, although the bulk LO phonons are more important to influence on the PCM. As increase of a magnetic field, the contribution from the two branches of 10 phonons tends to be comparable with that from the bulk LO phonons.

After thermodynamic studies on the former two typical fine disseminated gold deposits, the following facts are found: both existent and transferring form of gold in mineralizing hydrothermal solution are predominated by Au 〓 and AuH〓SiO〓; the contribution of AuCl〓〓 is negligible to mineralization; and those contribution of gold bearing complexes including Au with As-S and Sb-S are much less than that of Au 〓 and AuH〓SiO〓, organic complex take effect in some degree during the relatively low temperature activating period of gold.

Commencing from the basis of carrier's liability established in Hague Rules, this paper analyzes the relation between the ship interests'fault and general average contribution in conjunction with an introduction of the respective judicial practices and doctrines in United Kingdom, United States and China in this respect together with the understanding as to Rule D of York-Antwerp Rules 1974, and therefore concludes as follows:(1) No contribution may be collected from cargo where the general average was occasioned by the ship interests'fault, whether exemptible or actionable.

本文从《海牙规则》所确立的船东责任制度出发，结合英美两国及我国的司法实践和观念以及对《1974年约克-安特卫普规则》的规则D的理解，针对船方的过失与共同海损分摊之间的关系进行了探讨，并得出如下结论： 1、无论船方的过失是否可以根据法律或合同予以免责，只要该过失使得共同海损行为成为必要，船方就无权要求货方参与分摊。

It is shown that the generation of the PA effect results from two kinds of contribution only. One is the contribution of so called"thermal piston"--the gas boundary layer adjoining the heated sample which expands cyclically and pushes the rest gas just like piston. The compressing process of it is comfirmed to be isochoric. And the other is that of"mechanical piston"--the thermally expansive sample itself, the compressing process of which is found to be polytropic with a index of (2-〓).
