王靖略论--三槐王氏人物考之四

王靖是王冲之子,王旦的孙子,也是三槐王氏家族比较有作为的人物。但历史治宋史者,都没有注意到他。     

平话、湘南土话和粤北土话鼻音韵尾脱落现象考察

首先考察了平话、湘南土话和粤北土话中鼻音韵尾脱落现象的分布、特点,然后指出,平话、湘南土话和粤北土话之间共同存在的鼻音韵尾脱落现象不是其他方言影响的结果,而是其自身语言特点的保留,这为我们推测平话、湘南土话和粤北土话之间的密切联系再次提供了语言事实。     

基于BP神经网络的杭州湾北岸水下地形遥感反演研究

基于BP神经网络模型,利用同一时期的遥感影像和实测杭州湾北岸海图资料,构建了影像灰度值和水深值之间的单隐层BP神经网络模型,用以反演杭州湾北岸水下地形。结果表明,与传统的统计模型比较,所建神经网络模型反演地形的精度达84％。由此可见,基于影像灰度值和水深值建立的BP神经网络模型在反演海岸水下地形方面具有较强的应用价值。     

东亚三角涡虫肌球蛋白轻链（MLC）融合蛋白原核表达载体的构建及其在大肠杆菌中的表达

构建了涡虫肌球蛋白轻链融合蛋白原核表达载体,并进行表达,根据涡虫基因文库中肌球蛋白轻链（Mlc）基因完整的ORF序列设计合成特异性51物,通过PCR扩增涡虫Mlc基因,并插入到融合蛋白原核表达载体PET-28a中,转化宿主菌B121（DE3）细胞．0．4mMol／L的IPTG诱导表达MLc蛋白．重组质粒测序和酶切结果显示Mlc基因已正确插入PET-28a中,重组蛋白经SDS—PAGE在18．2KD处有一条明显的蛋白表达条带。western blot检测得到同样大小的条带。结果表明,涡虫His-MLC融合蛋白已成功表达。     

Using ~(137)Cs tracing technique to estimate wind erosion rates in the typical steppe region, northern Mongolian Plateau

Wind erosion is one of the major factors of land degradation in the typical steppe region, northern Mongolian Plateau. Using 137Cs tracing technique, we estimated the wind erosion rates of different pastures and abandoned farmland at Bayannur and Karakorum in Mongolia. The pastures and cutting grassland at Bayannur were slightly eroded by wind, with the rates of 64.58-169.07 t·km?2·a?1. The abandoned farmland in Karakorum, however, was strongly eroded by wind, with annual surface soil loss of 4.05 mm·a?1, and wind erosion rates up to 6723.06 t·km?2·a?1. The total loss of surface soil due to wind erosion has been 17.4 cm since the cultivation of the steppe land in the 1960s. The wind ero- sion rate at the abandoned farmland was much higher than that at the typical steppe sites, showing that the cultivation led to serious wind erosion in the typical steppe region, northern Mongolian Plateau. By contrast, traditional livestock grazing resulted in less disturbance to the surface soil, and did not in- duce to devastating wind erosion, which plays an important role in maintaining the stability of the steppe ecosystem in the northern Mongolian Plateau.     

一寺而兼两祖庭——论湖北当阳玉泉寺在中国佛教史上的地位和影响

被誉为“荆州丛林之冠”的湖北当阳玉泉寺在中国佛教史上有着极为重要的地位和影响.它既是中国第一个佛教宗派天台宗的祖庭之一,又是禅宗北宗的祖庭.此外玉泉寺还与其它佛教宗派如律宗、净土宗、禅宗南宗等也有着极为密切的关系.隋唐之时,玉泉寺高僧辈出,国师云集;诸宗竞秀,蔚为大观,是当时全国的佛教中心之一.     

王重阳与全真北宗的思想略论

以王重阳的思想为主,对道教全真道北宗的思想,从"识心见性"的心性论、先性后命的修道论、真功真行合一的功夫论三个方面探讨,比较北宗与南宗思想的异同以及北宗在思想史上的地位。     

程师孟诗考

程师孟,诗效白居易而尤简直,与之唱和往来的诗人不下百人.有诗集二十卷,惜已佚,故后世诗名不显.新编《全宋诗》从方志等辑其诗40首,用力甚勤,但《全宋诗》中的程师孟诗存在着疏失,需要对其加以考订、补苴,对其佚诗亦需加以考实.     

Zircon SIMS ages and chemical compositions from Northern Dabie Terrain: Its implication for pyroxenite genesis

We present the results of a detailed micro-scale investigation of zircons from pyroxenites, Daoshicong Northern Dabie using a combination of SIMS and ICPMS. The SIMS measurements gave ages of 134—159 Ma. Its average of (144.5± 6.2) Ma is interpreted as the best estimate of the pyroxenite intrusion. The crystallization of zircons continued for quite a long time and underwent slow cooling. The pyroxenites are products of post-collision magmatism. The REE pattern is HREE-enriched, and its HREE concentrations fall between the magmatic and metamorphic range of gneissic zircons from the Dabie area, which indicate the involvement of crust material in its mantle source.
