摘　　要：研究重铀酸盐产品的取样及制样方法。结果表明:采用内径为25 mm的探针取4次能够取到符合要求的样品质量,取3,4,5次对样品的代表性没有影响,由于产品的不均匀性,必须对产品进行逐桶取样;所采用的制样方法和粉碎设备能满足样品的均匀性要求。The size of sampling probe, the effect of sampling quantity on the representative sample, and homogeneity of yellow cake products are studied. The research results show that the approving samples can be got by sampling four probes（25 mm inner diameter）, and the same representative sample can be obtained by sampling 3-5 probes. Because the product is not homogeneous, each barrel product should be sampled. The method of preparation sample and the crushing equipment used can meet the demand of homogeneity
