11、实验条件的改革及建设，在目看来具有特殊的重要性。面对这种情况，我国的教育主管部门采取了一些推进实践教学改革及建设的措施。如：在全国高校本科的教学水平评估中，实验室基地建设与建设投资及其实验教学改革被列为一项重要的指标。并且，各高校也逐渐开始响应教育部的的这一举动，纷纷实行了“双基”型实验室2，与此同时，建设了“实验教学示范中心”。当前，传统实验教学模式的缺点主要有以下几点：验证性的实验所占比例较大，与综合性、设计性、创新性实验之间的比例失调；实验模式单一、实验室设备陈旧；实验教学中缺乏先进的实验教学手段。 The College of Engineering Education in Chin

43、将滤波器搭建起来。由于Simulink提供了丰富的元件库，采用图形化的表示方法，学生在进行算法验证的时候只需调用成熟的模块进行参数设计即可。这样的实验方法事半功倍，思路清晰，参数的调整也十分便捷，广受学生欢迎。由此可见，引入Simulink组件后的实验，既不会影响实验效果，又能够提高实验效率，对学生模块化编程的思想也有较好的促进作用。 The characteristics of the assembly, one hand can make the algorithm more simple, reduce the student input used in the verification
