园林植物相关知识是基于应用与实践的,植物类相关课程是一系列集理论、实践、应用于一体的课程。针对目前我校风景园林专业学生在学习、工作中对园林植物知识产生的实际需求与薄弱环节对园林植物类课程体系进行研究分析,探讨课程体系的优化途径。首先分析现有园林植物类课程的结构体系,明确课程定位和教学目标;其次结合学生学习现状及调研数据分析课程体系及授课方式存在的问题;最后通过调研明确课程改革及优化方向。为培养兼具植物专业知识和景观空间营造能力的专业人才做出贡献。 相似文献

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
