匀速直线运动模糊图像的退化数学模型试验研究
Through acoustic coupling of the transducer and the elastic plate , energy is transferred to the metallic plate , thus , the metallic plate ’ s flexural vibrating mode comes into being and driving force is produced by the legs ’ rectilinear motion
该马达振子由夹心式换能器和加工有齿的金属薄板连接而成。夹心式换能器激励金属薄板产生弯曲模态的振动,从而通过作斜线轨迹振动的齿产生驱动力。
The massive walking - beam rose and fell above the deck ; at one end a piston - rod worked up and down ; and at the other was a connecting - rod which , in changing the rectilinear motion to a circular one , was directly connected with the shaft of the paddles
甲板上露出一根很长的蒸汽机杠杆，两头一高一低地不停活动，这根杠杆的一端联接着活塞柄，另一头联着轮机上的曲轴，这样就把杠杆的直线推动力转变为直接推动轮机的动力，从而使轮轴不停地旋转起来。
