Quantitative characterization of fetal growth requires the selection of measurement parameters and a growth curve model. For such studies we propose two new parameters (the head cube and the abdominal cube) and a new growth curve model [P = c(t)k+s(t)]. These parameters are relatively insensitive to shape changes and are related to three-dimensional parameters even though they can be calculated from profile diameter measurements. The growth curve model is capable of adequately describing a wide variety of growth curves and its coefficients may be associated with specific biological variables. The properties of these parameters and the growth curve model are discussed.
胎儿生长的定量表征需要选择测量参数和生长曲线模型。对于此类研究，我们提出了两个新参数（头部立方体和腹部立方体）以及一个新的生长曲线模型[P = c(t)k + s(t)]。这些参数对形状变化相对不敏感，并且即使可以从轮廓直径测量值计算得出，它们也与三维参数相关。该生长曲线模型能够充分描述各种各样的生长曲线，并且其系数可能与特定的生物学变量相关。讨论了这些参数和生长曲线模型的特性。
