    本論文通過建立斜坐標系，簡化了計算過程，推導出了二次有理b樣條曲線曲率單調充要條件，並與二次有理b zier曲線的曲率單調條件相比較，結果表明：二次有理b樣條曲線曲率單調的充要條件與二次有理b zier樣條曲線相類似，但其條件又有不同。
  4. 2 % 22 % and 29 % respectively less than using other three knives at cutting speed of 500mm / min when the moisture contents of rootstalks was 48. 2 %. the cutting forces were tested at four different parts of rootstalk that were the middle part along a radius, the tip part along a radius, the middle part along axis and the stalk part along a radius, and the force at the middle along a radius is the largest and increase 32 % 45 % 111 %, respectively more than at the other three parts. the force increase 37 % to cut the rootstalks from the areas one crop a year more than that from two crops a year

    試驗結果表明，根茬含水率愈高，剪切力愈小，根茬含水率與剪切力近似為二次曲線關系；刀片剪切速度愈快，剪切力愈小；凸曲線、斜線、凹曲線和直線四種不同的刀刃曲線對整株根茬剪切力依此由小到大，凸曲線和斜線剪切時有一定程度的滑切作用，所以剪切力相比較小，當根茬含水率為48 . 2 ，剪切速度500mm min時，與其他三種曲線相比凸曲線型刀刃的剪切力依次分別減少了7 . 2 、 22和29 ；對根茬中部、梢部和根部的剪切力，在相同試驗條件下，徑向中部最大，比梢部，軸向根部和根部莖稈所需剪切力分別增加32 、 45和111 ；當含水率為48 . 2 ，刀片的剪切速度為500mm min時，一年一熟玉米根茬比一年兩熟的玉米根茬剪切力增大37 。
