采用X射线荧光、X射线衍射、热膨胀等分析手段对比研究了安阳商代陶水管的制作工艺,发现陶水管化学成分中各类熔剂的质量分数均略高于对比陶片中熔剂的质量分数,CaO、K2O、MgO等助熔剂与A l2O3的质量比进一步证实该现象,而这种差异性则外在地表现为陶水管的气孔度低于对比陶片以及陶水管热膨胀曲线中出现玻璃化现象,该结果表明陶水管原料应为一种易熔粘土,或者在沉淀粘土中人为地掺和了草木灰类掺和料,这有利于陶水管烧制与成型,有助于熔剂在熔融状态下,较好地进入陶水管中的空隙,使陶水管变得更加致密,一定程度上有利于防止陶水管的渗水,显示出陶水管制作工艺的特殊性。

The simulative model of temperature field and stress field in concrete , Heat and moisture coupling、Parallel simulative calculation of concrete with water pipe cooling、 Parallel feedback analysis of thermal characteristic parameters, and stress intensity factor of induced joint, which are the sixty-four-dollar questions, are studied in this dissertation. The main contents of this dissertation are as follows:(1)Based on the past and current research work, the calculation theory of the transient temperature field and creep stress field of mass concrete which self temperature influence is considered is deduced. The couple effect between the temperature field and humidity field of concrete, is considered on the basis of conservation law of water and energy, and the coupled formulation which coefficient is not constant of the heat and moisture in concrete is deduced. The calculation theory and model which is theoretically strict for solution to thermal problem in concrete with water-cooling pipes are recommended.
