本文以霍尔茨(HOLZER)法作为船舶轴系扭转振动的计算方法，着重研究了船舶轴系自由扭振的计算与分析，并对轴系扭振产生原因进行了分析，提出了一系列减振方法，以保证船舶动力装置的安全正常运行。(In this paper, Holtz (HOLZER) Act as the ship shafting torsional vibration calculation methods, focusing on the calculation and analysis of ship shafting torsional vibration of freedom, and the shaft torsional vibration causes analyzed, proposed a series of less vibration methods to ensure the safety of the ship s power plant running.)

数码管是一种半导体发光器件，其基本单元是发光二极管。数码管按段数可分为七段数码管和八段数码管，八段数码管比七段数码管多一个发光二极管单元，也就是多一个小数点（DP）这个小数点可以更精确的表示数码管想要显示的内容(The digital tube is a semiconductor light emitting device. Its basic unit is a light emitting diode. According to the number of digital tube can be divided into seven digital tube and eight digital tube, eight digital tube seven segment digital tube more than a light emitting diode unit is a decimal point (DP) of the decimal point can be a more accurate representation of the digital tube to display the content)
