A sausage of 4 cm diameter and 15 cm length was chosen as a model of a part of human extremities. On the snowfield the model was stood on end and its temperature was recorded continuously by means of thermistor thermorecorder. The conclusions are as follows: In fine weather the temperature directly under the sunny surface of a model rose higher than the air temperature by 18 degrees C in the most remarkable case. Even in cloudy weather it rose fairly though lower than in fine weather. The rise of a model temperature became higher in February than in January. Even at a depth of 1.0 cm the temperature rose fairly though lower than directly under the surface. The temperature of the shady side of a model was equal to air temperature or snow temperature. It is presumed from these data that the temperature of a human dead body on snowfield becomes higher and reaches a optimum temperature for putrefaction at least partly by the radiation of sunlight. The presumption is supported by our experiences at the autopsies in cold district.
选取一根直径4厘米、长15厘米的香肠作为人体四肢部分的模型。在雪地上将模型直立放置，并用热敏电阻温度记录仪连续记录其温度。结论如下：在晴朗天气下，模型受阳光照射面正下方的温度在最显著的情况下比气温高出18摄氏度。即使在多云天气，温度也会有所上升，尽管比晴朗天气时低。2月份模型温度的上升幅度比1月份更大。即使在1.0厘米深处，温度也会有所上升，尽管比表面正下方的温度低。模型背阴面的温度与气温或雪温相等。从这些数据推测，雪地上人体尸体的温度会升高，至少部分是由于阳光辐射而达到有利于腐败的最佳温度。这一推测得到了我们在寒冷地区尸检经验的支持。
