纤维支数是衡量苧麻纤维品质的主要指标。纤维支数的测定通常采用重量法,该法测定的结果虽然较为准确。但测定烦琐、效率低、费用高、样品量大。因此。如何简便地测定纤维支数一直是苧麻科研上探讨的问题。1984年吴越提出了苧麻纤维支数镜检法,即在显微镜下测得麻茎纤维细胞直径、壁厚,然后采用几个自设的公式,查用两次表、经过几次运算求得纤维支数,或者测得麻茎纤维细胞直径,壁厚,然后查有关表、图,得出纤维支数。作者在1983—1984两年中,经过反复探讨,另辟途径,研究苧麻茎纤维细胞壁截面积与纤维支数间的内在关系,求得了用麻茎纤维细胞壁截面积直接换算出纤维支数的公式。该公式只有简便、适用性广的特点,能保证一定的精度。在苧麻科研等实际运用中有一定价值。一、纤维支数与纤维细胞璧截面积回归模型推导
Fiber count is a measure of ramie fiber quality of the main indicators. Determination of fiber count is usually used gravimetric method, the method of determination of the results although more accurate. However, cumbersome determination, low efficiency, high cost, large sample size. therefore. How to measure the fiber count easily has always been the issue of ramie research. In 1984, Wu Yue ramie fiber count microscopic examination method, that is measured under the microscope stem cell diameter, wall thickness, and then use several self-formula, check the table twice, after several operations to obtain fiber Count, or measured stem stem cell diameter, wall thickness, and then check the table, figure, draw fiber count. The author in 1983-1984 years, after repeated discussions, another way to study ramie stalk fiber cell wall cross-sectional area and the inherent relationship between the fiber count obtained with the stem cell fiber wall cross-sectional area directly converted to the fiber count formula . The formula is simple, wide applicability characteristics, to ensure a certain accuracy. Scientific research in ramie and other practical use of a certain value. First, the fiber count and fiber cell cross-sectional area regression model derived
