麻单纤维强力估测模型的初步研究

Study on calculating model of ramie single fiber strength

苎麻单纤维强力与纤维细度之间存在着一元非线性回归相关，通过对１０７个品种的８１８对数据进行非线性回归运算，得到估测模型为＾ｙ＝３４１＋７０４８６１８／ｘ（其相关指数｜ｒ｜＝０９５００）。利用该模型，只需测出纤维细度，就可以计算出单纤维强力。

There is a unlinear correlation between the strength of ramie single fiber and the fineness of ramie fiber. The coefficient index r of correlation is 0 95. The calculating model can be expressed as: =3 41+ 70486 18 /x. According to this model, once the fineness of ramie fiber is known, the strength of ramie single fiber can be easily calculated. This model has a significantly practical value.
