浅谈汉语言文学教学中的审美教育研究

汉语言文学在提升人的个人修养和素质方面起到了很重要的作用。教师在对学生进行汉语言文学的教学的时候,要不断向着目标前进,不过在实际的教学中,主要因为汉语言文学本身的随意性较强,致使这门课很难合理控制。因此,在实际的学习中,我们要注重对学生的美学教育,用审美教育提升学生对美的理解能力,本文主要依据目前汉语文文学的教学现状,将审美教育揉合进入教育中,对其实施的可行性和必要性进行了相关的探讨。

A detection model of underwater topography with a series of SAR images acquired at different time

underwater topography is one of oceanic features detected by Synthetic Aperture Radar. Underwater topography SAR imaging mechanism shows that tidal current is the important factor for underwater topography SAR imaging. Thus under the same wind field condition, SAR images for the same area acquired at different time include different information of the underwater topography. To utilize synchronously SAR images acquired at different time for the underwater topography SAR detection and improve the precision of detection, based on the detection model of underwater topography with single SAR image and the periodicity of tidal current, a detection model of underwater topography with a series of SAR images acquired at different time is developed by combing with tide and tidal current numerical simulation. To testify the feasibility of the presented model, Taiwan Shoal located at the south outlet of Taiwan Strait is selected as study area and three SAR images are used in the underwater topography detection. The detection results are compared with the field observation data of water depth carried out by R/V Dongfanghong 2, and the errors of the detection are compared with those of the single SAR image. All comparisons show that the detection model presented in the paper improves the precision of underwater topography SAR detection, and the presented model is feasible.
