摘　　要：利用VB6.0对AutoCAD进行二次开发,采用AutoCAD提供的NURBS曲线精确表达船体横剖面线,并求出各种吃水下的各站横剖面面积及静矩.文章所用的方法无需绘制邦戎曲线,可节省时间,而且计算过程中利用NURBS技术替代梯形法或辛普森法,使得计算精度更高.在不同纵倾情况下,得到一系列的排水体积与浮心纵向坐标值,采用NURBS曲线插值即可得到费尔索夫图谱.To use VB6.0 to do the secondary development of AutoCAD, and then take NURBS curves supplied by AutoCAD to provide a more accurate expression of the transverse section of line, and with its functions, it will be easy to get the corresponding data of the transverse sectional area and its static moment quickly in accordance with the draught. Thus there is no need in the state using the Bonjean curve of the classical methods, which saves some time. What’s more, the intention to circumvent the Trapezoidal Rule or the Simpson＇s rule during the entire computation process ensures a more precise value of the calculation. Under different situation of trim, series values of displacement volume and longitudinal coordinates of the center of buoyancy can be calculated, and then with the utilization of NURBS curve interpolation, the Firsov＇s diagram shall be finally obtained.
