Moreover, the theory overall looked that, still wasat the rough stage, first was its basic parameter determination alsomust depend upon many experiences algorithms and the empirical data, roller distance, roller diameter, Next is many technical phenomenalike spiral curved waste product, the noise, theslanting roller characteristic, the slanting roller rollershape characteristic, the distortion match characteristic andso on all lacks the theory elaboration; Is once more the theoryconcise quality is insufficient, set of formulas not only cannotinclude each kind of cross section molding, even cannot include thesimilar cross section but the size and the material quality differentwork piece, like the curved distance and so on all lacks the generalexpression_r with the curvature.

另外，就矫直理论的总体来看，仍然处于粗糙阶段，首先就是其基本参数的确定还要依靠许多经验算法和经验数据，如辊数、辊距、辊径、压弯量及矫直速度等；其次是许多技术现象如螺旋弯废品、矫直缩尺、矫直噪声、斜辊矫直特性、斜辊辊形特性、拉弯变形匹配特性等都缺乏理论阐述；再次是理论的概括性不够，一套公式不仅不能包括各种断面型材，甚至不能包括同类断面而尺寸和材质不同的工件，如弯距和矫直曲率等都缺少通用表达式。

The results show that the flow length of microfluid in micro channels that have different section shapes but the same length(50 mm) is in inverse proportion to sections RPA (RPA means the ratio of the section s perimeter to its area),and the smaller the RPA , the longer the flow length.

研究结果表明：微流体在截面形态不同，长度均为50 mm微流道中的流动长度与流道截面的比表面积(截面周长与截面面积的比值)呈反比关系，比表面积越小，流动长度越大；当微流道的比表面积较小时，熔体温度与注射压力对流动长度的影响较大；当比表面积较大时，熔体温度与注射压力对流动长度的影响较小，且不论比表面积如何变化，注射压力对流动长度的影响比熔体温度对流动长度的影响显著。
