Based on soil radon gas survey in Quanzhou City and Jinjiang City, the authors conducted an investigation of the soil radon gas environment in an area of some 465 km2. The results indicate that radon gas concentrations in soils of Quanzhou and Jinjiang urban areas are at a lower level, whereas those in soils of Quanzhou and Jinjiang suburbs are at a fairly high level. It seems that the radon gas concentration is mainly related to geological background: radon gas concentrations in soils derived from weathering of adamellite, moyite, and biotite schist are higher than those in soils derived from weathering of other rock types.
通过泉州市、晋江市土壤中氡气测量,取得约465 km2土壤氡气环境调查成果,从结果来看,泉州市区和晋江市区土壤中氡气浓度普遍较低;市郊主要为山地,土壤中氡气浓度普遍较高;从土壤中氡气浓度水平的分布来看,土壤中氡气浓度水平主要与地质背景有关,二长花岗岩、钾长花岗岩、钾长浅粒岩及黑云片岩风化土壤中氡气浓度明显高于其他地质背景来源土壤。

Advance in the study of Neoproterzoic mafic-ultramafic rocks in the western margin of the Yangtze craton has been reviewed in this paper. These rocks consists of 0.95—0.90 Ga orogenic rocks and 0.86-0.74Ga anorogenic rocks, which reflect Neoproterozoic tectonic evolution from arc to intra-continental rift in the area.
本文著重总结和评述了扬子地块西缘的新元古代镁铁超镁铁质岩的最新研究成果,认为这一期岩浆活动是由约0.95~0.90 Ga造山带的岩浆活动和0.83~0.74 Ga非造山的岩浆活动组成,反映了从岛弧到板内裂谷的构造演化模式。

Results? 6 cases in X-ray film revealed round or oval stones in areatus distribution in the areas of renal papillae and medulla. 3 cases of IVP revealed cystic or hair-brushed dilation. 5cases in B-ultrasound revealed little anechoic area and strong echo light spot in radial distribution with acoustic shadow. Unenhanced CT of 6 cases revealed spotted or areatus stones surrounding minor renal calices with collecting tube system dilation and enhanced CT showed artifacts of stones magnification because of the collection of contrast medium around the stones. Conclusion?
结果 X线平片检查6例,表现为肾乳头、髓质区见簇状排列的圆形、椭圆形致密影;IVP检查3例,显示肾集合管囊状、刷子状扩张;B超检查5例见肾髓质内呈放射状分布的小无回声区和强回声光点,其后方伴有声影;CT检查6例,平扫呈环绕肾小盏分布的点状或簇状钙化灶,集合管囊状扩张,增强后因钙化周围的集合管内造影剂聚集,造成钙化影增大的假象。

The basic pattern of fairyland excursion combined with the life in seclusion had been created in the works of Sao tifu. The description of immortals in Hanfu was obviously different from the reflection on one's life experience by describing fairyland excursion in Chu Ci. What it pursued was mostly the pure fun in the fairland. The change of fairyland excursion from the heavenly spheres to the human worlds in Hanfu extended the space of artistic imagination of description of immortals. The fairy world in Hanfu was free and beautiful, which had become a symbol of spiritual realm of writers and the reflection of their interest in cloistral area.
汉赋将游仙与退隐相结合,开启了游仙隐逸化的基本表现模式;汉赋的游仙描写,已不完全是&楚辞式&的借游仙以抒怀,更多地表现出了真正意义上的&列仙之趣&;从楚辞到汉赋,游仙遇仙地点发生了由天界向人间的转变,从而进一步拓展了游仙描写的艺术想象空间;汉赋中的神仙世界自由美好,已成为文人精神境界的一种象征,寄托着赋作家遗世高蹈、超乎尘垢之外的人生志趣。

Study of the causes of MCS intensification and rainstorm shows that( 1) just before the heavy rains occur, there are high temperature, considerably wetness and unsteady convective stratification in the air over the rainstorm-hit area, in addition to significant increase in convectively efficient potential energy, condensation height and decrease in the height of free convection – all these favor the happening of the heavy rain,(2) the mergence of meso-βcloud clusters leads to the MCS such fast growth as to produce rainstorm,( 3) the two lines of cumuli in the north and west correspond, separately, to two convergences on the surface wind field, with stronger convergence at their meeting point responsible for such intense development of meso-βcloud cluster as to bring about torrential rains.
分析MCS加强和产生暴雨的原因表明,首先,暴雨发生前夕暴雨区域具有高温、高湿和对流性不稳定层结,并存在明显的对流有效位能增加、抬升凝结高度及自由对流高度降低的现象,有利于暴雨发生。第二,β中尺度云团之间的合并,使MCS迅速增长,产生暴雨。第三,北、西两条积云线分别与地面风场中的两条辐合线相对应,在它们交汇处的较强辐合导致β中尺度云团强烈发展产生暴雨。
