md-progress-circular和md-progress-linear是Angular进度指令，用于在应用程序中显示加载内容消息。

属性 - md-progress-circular

下表列出了md-progress-circular的不同属性的参数和描述。

Sr.No	参数和描述
1	* md-mode 从以下两种模式中选择一种:' determinate '和' indeterminate '。如果将md-mode值设置为undefined或指定为不是两（2）个有效模式中的1，则.ng-hide将自动应用为组件的样式; 如果未配置，md-mode =“indeterminate”将自动注入属性。但是，如果还指定了value =“”，则将自动注入md-mode =“determinate”。
2	value 在确定模式中，此数字表示循环进度的百分比。默认情况下，该值为0。
3	md-diameter 这指定了循环进度的直径。该值可以是百分比（例如'25％'）或像素大小值（例如'48'）。如果此属性不存在，则假定默认值为“48px”。
