The chemical composition,microstructures and the thermal behaviour of the bodiesand glazes for 31 typical sherds of the Guan and Ge wares were analysed. By using theunder-firing sherds,variations of the bodies and glazes under different temperatures andatmospheres were investigated.The essential conclusions are as follows: (1) The chemical composition of Guan ware glazes and Longquan Ge ware glazesare quite similar.When R_2O_3 is plotted against RO_2,both glazes fall within a narrowarea,bounded by two sloping lines. The relationship between RO_2 and R_2O_3 can be ex-pressed as RO_2-a/(R_2O_3)=kwhere k=6.2, a_(right)=0. 84 and a_(left)=-0.15, so △a≈1. (2) The data points for Xiuneisi Guan ware glaze, Ge ware glaze from Beijing Pa-lace Museum, and Jingdezhen imitation of Guan ware in Yongzhen period of Qing Dyn-asty all fall within this area, showing the ware glazes are similar to the Altar Guanglazes and the Longquan Ge glazes. (3) Results of quantitative analysis of phases show that in the glaze of green jadeappearance, the amount of anorthite is over 5%,and the total amount of CAS_2, quartz andbubble phases is greater than 15~20%, below which the glaze turns to be transparent. (4) When(RO·R_2O) is plotted against RO_2 in terms of body formula,the data pointsof the Guan and the Ge wares fall at either side ot the line which is represented by theequation: RO_2-2.2/(R_2O+RO)=kwhere k = 8.It is verified that"The Longquan Ge ware got its clay from Hongzhou" is un-reliable.

分析了官、哥窑器31种残片胎、釉的化学组成、显微结构和釉的受热行为。研究了郊坛官窑的生烧试样在不同气氛下各个烧成温度时胎、釉的变化。主要的结论如下: 1)在化学组成上,郊坛官窑釉与龙泉哥窑釉异常接近;按釉式以R_2O_3对RO_2作图,两者均落在一个以西斜线限定的狭窄区域内,用下列公式代表: (RO_2-a)/(R_2O_3)=k 式中 k=6.2,而a_右=0.84;a_左=-0.15,帮△a≈1。 (2)修内司官窑釉、故宫传世哥窑釉、清雍正景德镇仿官釉亦落入这个区域而与郊坛官窑及龙泉哥窑釉相近。 (3)物相定量结果证明;呈青玉感的釉,钙长石含5%以上;CAS_2、Q和B三相总量均>15~20%,低于此,釉趋于透明。 (4)以胎式按(RO·R_2O)对RO_2作图,官窑和哥窑在化学组成上有重大差别,分别处于下式: (RO_2-2.2)/(R_2O+RO)=k (k=8)为代表的界线两边。由此证明“哥窑取土于杭”的说法不足信。

An earthquake occurred in the study area in 1605,with a magnitude of 7.5,which caused the continental collapse to have formed the sea.For this area the seismicity is characteristic of 1)clustering in the north and south of the Hainan Island;2)migrating south-north;and 3)a definite seismic period.These kinds of formed characteristics may be related to the crustal isostatic disequilibrium responding to the uplifting of this island in the process of being deformed between the Eastern Asian continent that spreaded...

南岛1605年曾发生过7 1/2级强震,是一个有研究意义的地震活动区。海南岛地震活动有三个较显著的特征:集中分布于南北二个狭窄区域、具南北迁移现象和存在一定的活动周期和平静期。其特征的形成与海南隆起受东亚大陆向南推压和南海扩张向北推压所引起的地壳不均衡运动有关。

Results of quantitative metallography, SEM, EDAX and EMPA studies of Hf on the solidification of cast Ni-base superalloys are presented. The Hf is found to lower the liquidus temperature of the superalloys even the final solidification temperature to drop to 1130℃. The Hf may narrow down the range between temperature lost the interdendritic capillary feeding action and solidus, as well as may decrease the liquid content necessary for linking the interdendritic pools in the late solidification.

Results of quantitative metallography, SEM, EDAX and EMPA studies of Hf on the solidification of cast Ni-base superalloys are presented. The Hf is found to lower the liquidus temperature of the superalloys even the final solidification temperature to drop to 1130℃. The Hf may narrow down the range between temperature lost the interdendritic capillary feeding action and solidus, as well as may decrease the liquid content necessary for linking the interdendritic pools in the late solidification. The Hf-rich melts have superior fluidity, wettability and skin effect. These are the factors in increasing castability of Hf-containing superalloys. The Hf is not found in the dendritic arms of the superalloys, but is exceedingly concentrated in the narrow interdendritic zones usually in the form of Hf-rich phases. The Hf content in primary Hf-rich phases may be arranged in decreasing order of MC_(2), (Hf, Ti)_2 SC, Ni_5Hf, MC_(1) and eutectic γ'. The Hf may depress the formation temperature of primary phases. The solidification temperatures of all Hf-rich phases are lower than 1250℃. These phases may precipitate from the molten pools with Hf concentration over 13 wt-% at the late solidification and may have an intergrowth feature.

Hf降低铸造高温合金的液相线温度,使最终凝固温度降到1130℃。Hf缩小了失去枝晶间毛细补缩能力时的温度与固相线之间的温度范围,减少了凝固后期保持枝晶间液池连通状态所需的液体量。富Hf熔体具有良好的流动性并具有趋肤效应,这些都是含Hf合金可铸性增高的因素。铸造高温合金枝晶干不含Hf,Hf高度浓缩在枝晶间狭窄区域并常以富Hf相存在。富Hf初生相的含Hf量按下列次序递减:MC_((2)),(Hf,Ti)_2SC,Ni_5Hf,MC_((1)),共晶γ′。Hf降低了初生相的形成温度,所有富Hf相的凝固温度低于1250℃,它们都在凝固后期Hf浓度高于13wt-%的液池中析出,并具有共生特性。
