| 摘 要： | 泥炭的一个重要指标是灰分含量。目前化验室分析灰分含量采用烧灰方法,这种方法耗时费力,测一个样品需8小时左右。本文介绍用低能X射线反散射方法测定泥炭的灰分含量。这种方法简单、快速、测一个样品仅需1分钟。测量结果与化学常规分析比较,平均标准偏差约为3％。

| Abstract: | The content of ash in peat is determined by using the X-ray backscattering method. The radioactive source used is 238Pu. The average standard error is about 3% compared with those of chemical methods, and the causes of the error are discussed. |
