In的掺杂对化学水浴沉积SnS薄膜电阻率的影响 总被引：1，自引：0，他引：1
SnS and SnS：In films were deposited onto glass substrates by chemical bath technique. The structure and surface morphology of the SnS：In films were studied by X-ray diffraction （XRD） and scanning electron microscope （SEM） respectively. Energy dispersive spectroscopy （EDS） showed the existence of In in the films. The undoped SnS film exhibited a rather high resistivity and InCl3 could reduce the resistivity of these films by two orders approximately. The band gaps of the SnS and SnS：In films were evaluated from the optical transmission spectra. 相似文献

This paper will mainly address the rather controversy question in the study of learner strategies,that is,if learner strategies are teachable or not.I say it is controversy be- cause there are many pros and cons to this problem.Investigations from professionals in the field of strategies training have received many mixed results.In this article I shall try to argue that strategies should be teachable. In the first part of the essay,I shall give a brief literature review relating to this issue of the teachability of learner strategies.In this part the definition and different taxonomle8 of learner strategies should be mentioned.In the second part of the essay,I shall try to argue at first that learner strategies are teachable in general.In the third part of the essay I plan to discuss the vaiue of teaching strategies to students. 相似文献

A process of biosorption of Cu2 , Zn2 and Cd2 on Bacillus subtilis was investigated. The experiments show that the process of biosorption is quite fast. The maximum adsorption was reached after 5 min and hardly changed with time. The experimental data was analyzed using four sorption kinetic models: the pseudo-first-order, the Ritchie second-order, the modified second-order and the Elovich equations, which helped to determine the best-fit equation for the sorption of metal ions onto biomass. The results show that both the Ritchie second-order and modified second-order equations can fit the experimental data. The Langmuir model is able to accurately describe adsorption of Cu2 and Zn2 on B. subtilis. The experimental data points of adsorption Cd2 and Zn2 on B. subtilis are described by Freundlich isotherms model. 相似文献
