lever arm
    FQ increased by 10-40% after patele ctomy, while anterior displacement of the tibial tubercle by 1.5cm led to 11%-19% decrease because of its pro- longed lever arm.
    髌骨切除后该力增加10~40%,而胫骨结节抬高1.5cm该力减少了11~19%,因为后者力臂增长。
    Approach 2: the empirical expression of the flexural lever arm of the section, which was obtained by the statistics and regression of the experimental data, was adopted as the computational formula of the internal arm of forces in equilibrium conditions of the sections.
    算法2:采用了根据试验数据统计回归得到的截面内力臂表达式作为截面平衡条件中的内力臂计算公式,并将其作为截面有效受剪区域高度,大大地简化了迭代过程。
    Conception of lever arm coeffcients was introduced to solve eigenvalue problem of crankshaft system.
    本文引入"力臂系数"的概念,用于求解汽车发动机曲轴传动系统的扭转振动特征值问题.
    The method is based on that elements on major diagonal of transfer matrix are used as equilibrium lever fulcrum to calculate equivalent lever arm coefficients in the same column in order to uncouple equations and reduce orders of matrix and characteristic determinant, and as a result, simplify calculation work.
    力臂系数法是以传递函数矩阵主对角线上的元素为"平衡杠杆的支点",而求出同一行的等效力臂系数,使方程解耦并降低求逆矩阵的阶教和特征行列式的阶数.
    The whole process analysis of the cross section internal forces of reinforced light weight concrete beams was carried out. The internal lever arm coefficient (η) of tensile steel in cracking cross section is studied.
