• 中文摘要： 本文求出若干四維晶格上自旋為1/2艾辛模型之高溫磁化率級數至第8階。這些四維晶格為簡單超立方晶格、體心超立方晶格、超三角晶格及廣義等鄰晶格。假設在臨界溫度附近這些級數的發散情形為（方程式無法摘錄），本文考慮了數種分析這些臨界參數的方法。我們發現T 及　很難獨立求出。但是，如果　知道了，T 及A可以很容易求得。採用了再歸元群法之結果　=1/3，我們定出了前述四維晶格之臨界溫度為T 及臨界振幅A。
• 英文摘要： High-temperature susceptibility series for the spin-1/2 Ising model are obtained to the 8th order forseveral four-dimensional lattices: the simple hypercubic, the body-centered hypercubic, the hypertriangular,and the generalized equivalent nieghbor lattices. These series are analyzed by assuming a singularity of theform（方程式無法摘錄）. Several methods of analysis are considered. We find that it is difficult to deter-mine both T and 　 independently. However, if 　 is known, T and A can be determined easily. Adopt-ing the result of renormalization group approach, =1/3, we have determined the critical temperaturesT and the critical amplitudes A for various four-dimensional lattices.
