Department of Scientific History and Archaeometry; Graduate University of Chinese Academy of Sciences; Beijing 100049;4.Institute of Archaeology; Chinese Academy of Social Sciences; Beijing 100710; China;The fabrication technologies in terms of phase composition,structure,firing temperature,porosity,density and water permeability of ceramic water pipes and contrastive ceramic tilesexcavated from Anyang Yin Ruins of Shang dynasty were studied by X-ray fluorescence,X-ray diffraction and dilatometer,respectively.It was found that the contents of CaO,K2O,MgO and P2O5 in CWP were relatively higher than those in contrastive CT.The difference was further confirmed by the mass ratio of flux...

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。

For the case of n=2 and X〓 is generic, by using Picard-Fuchs equations and the argument principle Horozov and Iliev [36] gave the least upper bound of the number of zeros of I under the condition that X〓 has one center and three saddles.

当n=2且X〓为通有的Hamilton系统时，Horozov和Iliev[36]利用幅角原理和Picard-Fuchs方程给出了当X〓有一个中心、三个鞍点时I零点上确界的个数。

Based on our reduction of the ASCA observational data and fittings of the low and medium energy X-ray spectra, we combine the ASCA and BeppoSAX observed PG QSOs to form a sample for statistics of the spectral features on the X-ray spectra.

从处理ASCA观测数据和分析X射线谱出发，将有ASCA和BeppoSAX观测结果的PG类星体构成一个样本，对它们的中、低能X射线谱上的观测特征进行统计。

The first assignment successfully converts the lambda expression to the delegate type Func because, when x is given type int, x+1 is a valid expression that is implicitly convertible to type int.

第一个赋值成功地转换 lambda 表达式到 delegate 类型 Func ，是因为当 x 是 int 型， x+1 是一个有效的表达式并可以隐式地转换到类型 int 。
