摘孔孟家谱 要:选取50名中老年人作为受试者进行皮褶厚度的测量,整个实验过程采用体成分分析仪(INBODY)、日本营养研究所皮脂专用钳进行测试,采用数理统计法进行统计,将测试数据与公式推算的数据进行绝对误差和相对误差的比较分析。研究表明,不同皮褶推算公式结果与测试结果均存在不同差异,男女之间也存在不同差异,不同推算公式的有效性不同。其中公式一对于男性的绝对误差和相对误差最小,公式二对于女性的绝对误差和相对误差最小。对男性有效性较高的推算公式是F%=0.187X1+0.187X2+0.094X3+13.896,对女性有效性较高的推算公式是F%=0.071X1+0.098X2+0.226X4+8.612。

Abstract解郁丸说明书:个人独资企业章程The skin fold thickness of 50 elderly as subjects was measured with body composition analyzer (INBODY) and bum pliers by Japan Institute of Nutrition, and then the data was procesd with mathematical statistics. The test data and formulas derived data were compared bad on absolute error and relative error. Studies show tha
1990年属马五行属什么t the skin fold projection formula vary from measured results, and that there are differences between men and women, and that different formula have different validity. Formulas I for men has smallest absolute error and relative erroroppo手机黑屏, while Formulas II has minimized absolute error and relative error for women. The formulas that has higher effectiveness for men is F% = 0.187X1+0.187X2+0.094X3+13.896, while that for women is F% = 0.071X1+0.098X2+0.226X4+8.612.
