Erythrocyte sedimentation rate was measured in a physiological saline solution as a function of both the tube diameter d and the initial suspension length iota 0. All the sedimentation curves in the vertical tubes were found to overlap over the range 1 mm less than d less than 7 mm and 100 mm less than iota 0 less than 330 mm, within the precision of 8 %. The sedimentation curves in the tilted tubes fit well to an exponential equation of iota = a [1 - exp (-bt)], where iota and t are the medium length along the tube and the elapsed time from sample injection respectively: At fixed tilt angle theta and iota 0, a was roughly constant and b was roughly proportional to l/d, while at fixed theta and d, a was linearly proportional to iota 0 and b was constant. The initial slope ESR (theta) = (d iota/dt) t----0 = ab was represented by a unique straight line as a function of iota 0/d for each fixed tilt angle. The experimental results were compared with some recent theories.
在生理盐溶液中测量红细胞沉降率，它是管直径d和初始悬浮液长度ι₀的函数。发现在垂直管中，所有沉降曲线在1毫米＜d＜7毫米和100毫米＜ι₀＜330毫米的范围内重叠，精度为8%。倾斜管中的沉降曲线很好地拟合了ι = a [1 - exp (-bt)]的指数方程，其中ι和t分别是沿管的介质长度和从注入样品起经过的时间：在固定倾斜角θ和ι₀时，a大致恒定，b大致与l/d成正比，而在固定θ和d时，a与ι₀成正比，b恒定。初始斜率ESR(θ) = (dι/dt) t----0 = ab对于每个固定倾斜角，作为ι₀/d的函数由一条独特的直线表示。将实验结果与一些最新理论进行了比较。
