A simplified wave-mechanical method of deriving the temperature factor in the reflection of X-rays from crystals is given(1). The general expression for the function M is the same as calculated by Zener and Jauncey. Hence the discrepency between Zener's theory for hexagonal crystals and the experiments may be due to the special model used in his calculation.

由简单之波动力学计算,求得Debye-Waller函数结果与Zener及Jauncey者相同故Zener对六角结晶之理论与实验结果之差异,或因其计算中所用之特殊模形所致。

1,3-Pentadiene prepared from acetylacetone in our laboratory contained 91.7% trans and 8.3% cis-isomers. Homopolymerization of 1,3-pentadiene and its copoly-merization with butadiene were carried out with heterogeneous catalysts prepared from NdCl3-C2H5OH-Al(C2H5)3 in hydrocarbon solvent. The results obtained showed that only trans-isomer of 1,3-pentadiene can be polymerized with these catalyst to high molecular weight polymer with high conversion. The structure of the polypen-tadiene has been examined by IR, NMB and X-ray spectra. It was found that the polymer contains predominantly cis-1,4-unit with isotactic configuration and exhibits crystallinity. The data obtained by IB and dynamic mechanical method indicated that the product of copolymerization by above mentioned catalyst system is a random copolymer.
