模糊优化在柔性路面结构可靠度设计中的应用

现行的可靠度设计方法只考虑了各设计基本变量的随机性,而没有考虑它们的模糊性,本文将可靠度理论与柔性路面结构优化设计方法结合起来,并充分考虑各种影响因素的模糊性,提出了更科学、更合理的模糊优化设计方法.     

黄淮地区月极端气温概率模型

利用黄淮地区１４个国家基本（淮）站１９５１～１９９３年４０余年的月极端气温资料序列,分别进入了正态、Ｇｕｍｂｅｌ、Ｗｅｉｂｅｌｌ概率分布的拟合试验,通过拟合检验植和误差,确定了各站月极端最高气温和极端最低气温的概率分布模型,为气候分析和气候预测提供了一项基本依据。     

热历史对Sialon／SiC_（p）复合陶瓷的相稳定性及力学性能的影响

研究热处理对致密Ｌｎ－Ｓｉａｌｏｎ／ＳｉＣ（ｐ）复合陶瓷中α相稳定性的影响及由此引起的显微结构调控和力学性能变化，其中Ｌｎ＝Ｎｄ和Ｙｂ．Ｎｄ－Ｓｉａｌｏｎ／ＳｉＣ（ｐ）中，α相热稳定性差，几乎全部相变为β相，而大量长柱状β晶粒的存在并未明显改善材料的断裂韧性（ＫＩＣ），原因在于长时间热处理导致晶粒相互聚集粗化．相对而言，Ｙｂ２Ｏ３可有效稳定α相，因此Ｙｂ－Ｓｉａｌｏｎ／ＳｉＣ（ｐ）中含有许多等轴状α晶粒，高硬度是此种材料力学性能的显著特征．     

须条与长丝间距对Sirofil成纱结构性能的影响

分析了Sirofil纺纱过程中“V”形区的动态变化及粗纱须条与长丝间距大小对“V”形区形状和单纱受力的影响,认为间距增大会使“V”形区夹角增大、单纱段长度变长,并以此为依据,保持其他工艺参数不变,改变粗纱与长丝间距大小,试纺Sirofil纱,通过理论分析和实验比较讨论间距大小对Sirofil成纱结构性能的影响。结果表明：随着间距增大,成纱直径系数趋小、毛羽减少、强伸性与条干均呈非单调性变化;综合考虑成纱结构和性能,在其他参数相同时,Sirofil最佳成纱间距为12～16mm。     

"钦天监教案"起因探析

"钦天监教案"是清初多种矛盾激化的必然产物一、中西历法之争最后演化为"夷夏之辨"的政治斗争,给辅政大臣铲除政敌提供了借口;二、天主教势力的迅猛发展威胁到佛教的传统地位,使两教矛盾激化;三、汤若望在政治上的巨大成功损害了一部分满清权贵的政治利益;四、传教士内部的内讧给反汤若望势力可乘之机;五、汤若望成为辅政大臣清算"汉化"思潮的牺牲品.     

Lower Cambrian small shelly faunas from Zhejiang (China)and their biostratigraphical implications

Despite a long history of research on the Early Cambrian in China most available data on small skeletal fossils concern fossil associations of the shallow carbonate platform. Information on skeletal fossils from marginal shelf environments of the Yangtze Platform is scanty, which may reflect the rarity of fossils in deeper sedimentary environments but is also due to limitation of carbonate distribution and outcrops, difficulties in fossil extraction, and a general research focus on the Precambrian-Cambrian boundary beds on the carbonate platform. Here we present a documentation of Meishucunian to Qiongzhusian small skeletal fossils from the lower Hetang Formation and the chert unit at its base from the Jiangshan region, Zhejiang Province, representing a relatively deep shelf environment compared to the inner shelf region. The earliest association (Meishucunian) from the chert unit underlying the Hetang Formation is mainly characterized by the occurrence of Protohertzina anabarica, P. unguliformis, Fengzuella zhejiangensis, and Kaiyangites novilis, which differs somewhat in composition from SSF-associations of typical inner shelf deposits. The enigmatic skeletal fossil Fengzuella zhejiangensis, which exhibits an unusual secretional growth mode previously unrecognized from the Early Cambrian, is described in detail. A younger (Qiongzhusian) fossil association contains numerous arthropod remains, such as disarticulated spines of arthropods (Jiangshanodus- and Kijacus-type), which have previously been considered as conodont-like fossils, and bradoriid valves.     

浅析诗味论的接受美学蕴涵

接受美学是20世纪60年代兴起的一种世界性的理论潮流,在文学美学界引起了普遍关注。“味”是中国古典诗学中的重要美学范畴,经过众多文论家的阐发,形成了独具中国特色的诗味论。诗味论与接受美学在关注读者与文本上存在着相通或相似之处,将两者放在一起考察有助于在对我国优秀的古典美学资料进行开发整理的同时,加强中西文论的交流与对话,进而促进当代文学批评范畴的建构。
