论陶渊明的“志道”之学与“立名垂世”思想

“士志于道”是儒家据以评判士之是非善恶的最高价值标准。“志道”之学,指中国古代知识分子自觉地追求儒家的道德境界,并以此作为立身处世的终极价值依据。而传统的“三不朽”理论又以“立德”为上善之选,这就为知识分子从“立德”走向“不朽”提供了内在依据。陶渊明的“立名垂世”思想,是指他在“志道”的践履过程中所形成的指向“不朽”追求的价值意图,即通过“三不朽”的操作体系以实现垂名后世的价值理想。所不同的是,陶渊明用“志道”之学为自己的“立名垂世”思想做了策略性的解释。

Feasibility of a Lidar Utilizing the Glory for Measuring Particle Size of Water Clouds

A new lidar method for measuring water cloud particle size is proposed, and the feasibility of the measurement is discussed. The method utilizes the phenomenon known as the glory which is observed in open air. The proposed lidar consists of a multicolor laser transmitter and two receiver systems looking at the scattering from the target cloud with different scattering angles. Results of the theoretical study show that a system with five laser wavelengths (355, 532, 750, 1064 and 1500 nm) and two receivers located at scattering angles of 180 and 177.5–179 deg is useful for measuring particle size (mode radius of the size distribution) in a range of 4 to 12μm.     

韶州曹溪在禅宗发展中的重要地位和作用

惠能与韶州曹溪宿昔有缘,生在新州,得法黄梅,广州剃度,却在韶州曹溪行化四十多年,并把真身永久地留在了曹溪宝林寺.韶州曹溪是惠能黄梅求法的准备出发地,又是他回到岭南的首选避难地,还是禅宗宝典《坛经》的演绎创作地.曹溪宝林寺更因为惠能的到来而得到繁荣发展,最终成为岭南禅宗祖庭.惠能用曹溪法乳,孕育了一大批禅宗大师.他们又背靠岭南,立足曹溪,挺进中原,最终推动南禅顿宗发展成花开五叶、五家七宗的繁盛局面,“凡言禅皆本曹溪”也就顺理成章了.禅宗文化在韶州曹溪的发展使韶文化大观园中增添了新的姿采.     

Two-Color Dual-Polarization Pulsed Bistatic Lidar for Measuring Water Cloud Droplet Size

The concept of a pulsed bistatic lidar for measuring water cloud particle size is presented. The method uses a two-color laser and a receiver with a polarization analyzer located at a suitable scattering angle. The dependence of Mie scattering on scattering angle, wavelength, and polarization is used to derive water cloud droplet size. The measurement was simulated for the C₁ and C₂ clouds, and the technique for determining mode radius was studied. The result shows the lidar system with a two-wavelength laser (1064 nm and 532 nm) and a dual-polarization receiver fixed at a scattering angle of around 178 deg can be used to measure a cloud particle size (mode radius) of 4 to 12 μm. Evaluation of the effect of multiple scattering showed that the method can be applied not only for the measurement at the cloud base but also in the cloud where multiple scattering is not negligible.     

桂林全新魅力气象景观资源评价初论

桂林风光中的山、水、溶洞已有相当深度的开发,宝光、日出、烟雨、云海和云霞等气象景观将是桂林未来颇具开发观赏魅力的重要景观资源之一.本文通过对桂林气象景观资源的初步评价,提出开发大桂林气象景观资源的总体思想:在不影响现有桂林山水景观格局情况下,开辟必要的新游路及数量相当的新景点,以引导游客把欣赏桂林风光的视角从地表的山水、溶洞延伸到空中旖旎的宝光、飘渺的烟雨、壮观的云海和瑰丽的日出等气象景观上,使人们对桂林风光的感受更接近想象中的"仙境".
