Rates of movement of univalents at prometaphase and of half-bivalents at anaphase in living cricket and grasshopper spermatocytes were determined as a function of the distance from the pole toward which the movement was directed. In the artificially produced univalents of cricket cells, correlation coefficients for rate versus distance form the pole were widely disparate from movement to movement and there was no consistent relationship between velocity and distance from the pole. However, in the naturally occurring univalents of grasshopper cells, there was a significant positive correlation between velocity and distance from the pole. In both cricket and grasshopper cells, there was no consistent correlation between rate of movement and distance from the pole for half-bivalents at anaphase. The prometaphase data from grasshopper cells support the simple hypothesis of Ostergren (1950) that congression results from the application to chromosomes of forces which increase with increasing distance from the pole. Furthermore, these data are consistent with models of force production which suppose that the relationship between force (reflected as velocity) and distance from the pole is a linear one.
测定了活蟋蟀和蚱蜢精母细胞中前中期单价体以及后期半二价体的移动速率与朝着移动方向的极之间距离的函数关系。在蟋蟀细胞人工产生的单价体中，速率与距极的距离之间的相关系数在不同移动之间差异很大，速度与距极的距离之间没有一致的关系。然而，在蚱蜢细胞自然存在的单价体中，速度与距极的距离之间存在显著的正相关。在蟋蟀和蚱蜢细胞中，后期半二价体的移动速率与距极的距离之间均没有一致的相关性。蚱蜢细胞的前中期数据支持了奥斯特格伦（1950年）的简单假设，即染色体向赤道板移动是由于施加在染色体上的力随着距极距离的增加而增大。此外，这些数据与力产生模型一致，该模型假设力（以速度反映）与距极的距离之间的关系是线性的。
