本程序的功能就是在后台播放音乐，没有多余的界面。"选择目录"里的路径可以自己输入，也可以将音乐文件夹拖到程序的窗口中。"选择歌曲"能选择自己喜欢的歌来听，只要将音乐文件拖到窗口即可，但拖一首歌就要激活本程序的窗口，再按一下回车，才可以选择第二首歌。这里比较麻烦，我会努力解决问题。最重要一点就是，"选择歌曲"里，歌曲名称不能有空格，技术问题，请多多包含。-This procedure of its function is to play music in the background, there is no extra interface.

在遥感应用领域，植被指数已广泛用来定性和定量评价植被覆盖及其生长活力。由于植被光谱表现为植被、土壤亮度、环境影响、阴影、土壤颜色和湿度复杂混合反应，而且受大气空间―时相变化的影响，因此植被指数没有一个普遍的值，其研究经常表明不同的结果。-in the field of remote sensing applications, vegetation index has been widely used for the qualitative and quantitative evaluation of the growth of vegetation cover and its vitality. As the spectral performance of the vegetation cover, soil brightness, environmental impact, shadow, color and soil moisture complex mixed reaction and by the atmospheric space-phase change, vegetation index therefore not a universal value, its regular show different results.
