Research Equipment: Cinemicrography, Projection and Image Analysis Systems for Crystal Growth Studies

将获得一台电影摄像机和辅助图像分析设备，用于正在进行的研究工作，具有非常先进的能力，以实验研究树枝状晶体生长的基本问题。这项工作的出发点是，它将试图在冰和丁二腈的树枝状生长的背景下解释能量和溶质的自由和强迫对流，这意味着必须考虑形状和图案的形成。这里提供的电影显微摄影系统和图像分析设备，结合目前对自由和强制对流生长细胞的宏观、温度测量和控制，提供了以所需精度进行必要测量的能力，以显著增强我们对枝晶生长和图案形成的理解，这是许多新材料开发的基础。

A motion picture camera and auxiliary image analysis equipment will be obtained for an ongoing research effort with a greatly advanced capability to study experimentally the fundamental problem of dendritic crystal growth. The point of departure of this work is that it will attempt to account for both free and forced convection of energy and solute in the context of the dendritic growth of ice and succinonitrile which means that shapes and pattern formation must be considered. The cinemicrography system and image analysis equipment provided here, in conjunction with the present wild macroscope, temperature measurement and control for the free and forced convection growth cells provides the capability of making the necessary measurements with the precision required to enhance significantly our understanding of dendritic growth and pattern formation which is fundamental in the development of many new materials.
