简介:摘要在地球物理勘探中,地震资料计算机显示方法主要有变密度彩色显示、波形显示、变面积黑白(填充波形)显示等,其中变面积显示方式在数据采集和资料处理阶段使用最为广泛。现有变面积显示技术在查看小范围数据时波形填充显示效果比较好,当扩大显示范围时由于屏幕分辨率限制,只能对波形进行抽希显示,这种现实方法精度不高,显示效果不美观。本文提出一种基于灰度的变面积绘制方法,将像素位置看成一个单元,首先统计要填充的波形落在单元内部的强弱权值,最后根据每个单元内的波形权值设置像素的颜色深浅,即使用颜色的深浅表示波形的强弱。实验表明,本文提出方法绘制的地震剖面显示精度更高,效果更加美观。
简介:摘 要: 思维导图是一种有效的创新思维工具,它把知识点与知识点之间相关联,使思维可视化。思维导图主要是从中心概念出发,向四周发散,将知识以脉络的方式呈现出来。政治 学科知识点多、 理论性强 , 通过思维导图学生可以把零散的知识组合起来,形成有条有序的知识网络,有利于培养学生的发散性思维能力。论文 以高中《政治生活》为例,分析 思维导图在高中政治主观题复习中的应用,探索优化高中政治主观题复习策略,提高学生解答主观题的能力,让学生拿高分。 Abstract: Mind mapping is an effective innovative thinking tool, which links knowledge points with knowledge points and visualizes thinking. Mind mapping mainly starts from the central concept and spreads around, presenting knowledge in the way of context. Political science has many knowledge points and strong theory. Through mind mapping, students can combine scattered knowledge to form an orderly knowledge network, which is conducive to cultivating students' divergent thinking ability. This paper takes "Political Life" as an example to analyze the application of mind mapping in the review of high school political subjective questions, explore and optimize the review strategy of high school political subjective questions, improve students' ability to solve subjective questions, and let students get high marks.
