WebFractionated crystallization occurred in these PVDF nanodroplets with the heterogeneously nucleated crystallization in the range of 105–135 °C and the homogeneous nucleation at 55–60 °C. The mechanism of homogeneous nucleation was confirmed by the study of crystallization kinetics using differential scanning calorimetry. In optics and especially laser science, the Rayleigh length or Rayleigh range, , is the distance along the propagation direction of a beam from the waist to the place where the area of the cross section is doubled. A related parameter is the confocal parameter, b, which is twice the Rayleigh length. The Rayleigh length is particularly important when beams are modeled as Gaussian beams. 在光學及雷射科學中，瑞利距离或瑞利长度（Rayleigh length）或瑞利範圍（Rayleigh range）是指光束沿著其行進方向，從其腰部到其面积為腰部面积兩倍的截面的距離，此时截面半径约为倍的腰部半径。另一個相關的參數為共焦參數（confocal parameter）b，恰為瑞利距离的兩倍。當用高斯光束來做為光束模型時，瑞利距离是相當重要的參數。 fish that may be hard to fillet crossword
