通过电子显微镜研究了在 5-150 托压力下在 He、Ne、Ar 和 Xe 气体中制备的 Cds 颗粒。具有纤锌矿结构的晶体以单个六方板或棱柱或以由三个或更多个六方棱柱组成的更复杂的形式生长。如果在较重的气体中制备，则颗粒的平均尺寸较大，并且几乎随气体压力线性增加直至饱和压力，对于较重的气体，饱和压力较低。给出了不同气氛下烟雾中的颗粒尺寸分布和室内的温度分布，并在此基础上讨论了颗粒的生长。
Cds particles, which were prepared in He, Ne, Ar, and Xe gases at pressures of 5–150 Torr, were studied by electron microscopy. Crystals with wurtzite structure grew in single hexagonal plates or prisms or in a more complicated form composed of three or more hexagonal prisms. The mean size of the particles was larger if they were prepared in a heavier gas, and increased almost linearly with gas pressure up to a saturation pressure which was lower for heavier gasses. The particle size distributions in the smokes and the temperature distributions in the chamber are presented for various atmospheres, and on these bases the growth of the particles is discussed.
