bootstrap.cssis the core css for BootStrap that defines all the style for various controls/components, where as bootstrap-theme.cssdefines the themes (gradient/animation) for buttons,dropdown menu,navbar,progressbar,panels.
bootstrap.css是 BootStrap 的核心 css，它定义了各种控件/组件的所有样式，其中 asbootstrap-theme.css定义了按钮、下拉菜单、导航栏、进度栏、面板的主题（渐变/动画）。
Most of the times adding bootstrap.cssis enough for bootstrap to work, but for gradient/animation, you can use bootstrap-theme.css.
大多数情况下，添加bootstrap.css足以让引导程序正常工作，但对于渐变/动画，您可以使用bootstrap-theme.css.
You can see the difference on http://getbootstrap.com/css/#buttonsand then click on Preview theme from the affix menu (fixed menu on right side)
您可以在http://getbootstrap.com/css/#buttons上看到不同之处，然后从词缀菜单（右侧的固定菜单）中单击预览主题
