机械设计基础是高等院校有关工科专业一门重要的技术基础课。目前这门课程在我校十余个专业分两种类型开设，一类是近机械专业如粉冶、探工、压加等，开课学时为80学时，其中包括6个实验学时；另一类专业如无机、选矿、冶化等为68学时，其中包括4个实验学时。为配合课堂理论教 The basis of mechanical design is an important technical basic course for engineering major in colleges and universities. At present, this course is divided into two types in more than ten professions in our school. One is the recent mechanics such as powder metallurgy, exploration workers, pressure increase, etc. The starting class is 80 hours, including 6 experimental hours; the other class Professional such as inorganic, mineral processing, metallurgy and other 68 hours, including 4 experimental hours.
