We conducted research into origin and type of coal excavated by Mado I in Taean, Korea.The type of coal was proven pitch coal (subbituminous coal) through X-ray diffraction analysis, the measurement of carbonization degree, technical analysis and elementary analysis.Pitch coal (subbituminous coal) was excavated in Jangi and Dogu in Pohang, Korea.The caloric value from coals in Dogu is 8,029kcal/kg which is similar to the caloric value 8,136kcal/kg from coals excavated by Mado I.The volatile matter in Jangi is 47.07% similar to that of coals by Mado I, 49.40%.But the main component of fly ash was different in both sites.The component analysis of fly ash could be very different according to a seam of coal even though excavated in the same sites.As a result the coal excavated by Mado I could be brought from Jangi and Dogu in Pohang.

对34件吴国青铜容器样品进行了金相观察和成分分析,发现器物均为铸造成型,材质多为铅锡青铜,含砷的青铜也有一定数量.铅含量普遍偏高和含砷青铜的存在是吴国青铜容器的两大合金特点.这一工作为了解两周时期吴地的青铜铸造业,尤其是容器的合金技术,提供了新的数据.同时也为了解吴地与中原及其它地域在青铜技术方面等的传播交流提供了新的资料.此次检测的34个样品取自26件器物。分析的这批吴国青铜容器的材质以铅锡青铜
