略论闽南方言与唐诗韵律——以杜甫诗作为例

与普通话相比,闽南话的文读音在吟诵唐诗、复原古音古韵上有着明显的优势。这一情形的出现,源于闽南话的文读音系统,在韵母的分化、鼻音韵尾的分合、等呼的简化归并,以及入声韵的存佚等方面,都远比普通话更为贴近《切韵》音系的原貌。而这一唐韵犹存的语音系统,也成为了我们重新涵咏体会唐诗的宝贵桥梁

Load Balancing Algorithm for Path Planning Based on Shared Memory

为满足前端对路径规划高并发服务需求,本文设计后台采用集群路径规划服务器来实现并行处理,以达到对前置Fast CGI服务器请求进行分流的目的。由此,本文提出基于共享内存的路径规划负载均衡算法,可根据不同路径规划服务器的性能差异,设置相应的加权系数,并按照加权调度算法,将任务交由合适的路径规划服务器来处理,以均衡所有路径规划服务器之间的负载能力,减少服务延迟,从而提高了路径规划服务的稳定性、扩展性、高可用性和执行的效率。To meet the front end on the path planning for high concurrency service needs,this paper designs background using cluster path planning server to realize parallel processing,in order to achieve the diversion for the prepositive Fast CGI server requests.Thus,this paper presents the load balancing algorithm for path planning based on shared memory,which can set the corresponding weighting coefficient based on the differences in the performance of different path planning server,and according to the weighted scheduling algorithm,the task to be processed by the appropriate path planning server.The result shows that this way can not only balance between all path planning server load capabilities,but reduce the server delay,so as to improve the stability of path planning service,expansion,high usability and execution efficiency

Mechanism of Functional Molecules in Shape-Control Synthesis of Noble Metal Nanocrystal Catalysts

金属纳米晶催化剂(简称金属纳米催化剂)广泛应用于化学、能源等现代工业。铂等稀贵金属目前仍然是燃料电池等领域不可替代的催化剂材料,进一步提高金属催化剂的性能和利用率一直是重大挑战。金属的表面结构取决于晶体的形状。因此,形状控制合成可有效地调控金属纳米晶催化剂的表面结构和性质,近年来得到了大量研究。功能分子(保护剂、稳定剂、表面活性剂、添加剂等)对金属纳米晶的形状控制合成具有重要作用,尤其是在湿化学法形状控制合成中。深入认识功能分子在形状控制合成中的作用机理,可为理性地设计和制备具有特定功能的纳米催化剂提供指导。功能分子通常是通过在纳米晶核特定晶面上优先吸附,或刻蚀某些特定的晶面,或者加速或抑制某些晶面的生长实现对纳米晶催化剂表面结构的调控。虽然通过结构控制合成的电化学法和湿化学法已经制备出大量不同表面结构的金属纳米晶催化剂,但是对功能分子作用机理的认识还远未深入。本文综述了近二十年金属纳米晶催化剂形状控制合成的进展,侧重阐述对功能分子作用机理的研究,总结了功能分子在金属纳米晶催化剂形状控制合成中优先吸附的重要作用机制,以及优化功能分子在纳米粒子形状控制合成中的一些基本策略。Metal nanocrystal catalysts(abr.metal nanocatalysts) are widely used in chemical and energy industries.The rare and precious metals as platinum are actually irreplaceable materials for catalysts,therefore to improve the activity and utilization efficiency of metal catalysts is always a challenge.Shape-control synthesis is an efficient way to tailor the surface structure of metal nanocrystal and therefore create particular functions in catalysis.The functional molecules such as stabilizers,capping agents,surfactants and additives,etc.,are indispensable in the shape-control synthesis,especially in the wet chemistry route.In order to rationally design and synthesize metal nanocatalysts with high activity,high selectivity and high stability,it is important to explicit the roles and mechanisms of functional agents in shape-control synthesis.The functional agents usually assist in shape-control synthesis of nanocrystals through preferential adsorption on specific crystal facets,or etching particular crystal planes,or accelerating / inhibiting certain crystal growth directions.Although a mass body of metal nanocrystals with different shape have been synthesized,the explicit roles and mechanism of functional molecules in the shape-control synthesis are poorly defined and a full understanding is still elusive.The current paper reviews mainly the recent progress made in studies of mechanism of functional molecules in shape-control synthesis of metal nanocatalysts in the last two decades.The mechanism of preferential adsorption of functional agents and some basic strategy of optimizing the use of functional molecules in shape control synthesis of noble metal nanocatalysts are summarized.国家自然科学基金“界面电化学”创新研究群体项目(No.21021002)资

Discussion on who's who and Examination Method for Royal officials

《人物志》的撰写与“都官考课“的制定,是刘卲一生的两大创造。“都官考课“的制定,是以理想中的汉代察举制度为蓝本的;而《人物志》所反映出的却是一种带有名士趣味的观人法则。两者旨趣的背反,与汉魏之际急剧变动的时代风气息息相关。who's who and Examination Method for Royal officials("Du guan kaoke")are two big achievements by Liu Shao.The relationship between those two, however, lacks detailed analysis.This article puts forward that the enactment of Examination Method for Royal officials takes the election system in Han Dynasty as the chief source, while who's who shows the rule to observe people, which features the interesting way by persons of literary reputation.The difference in objective is closely linked to the social mores--dramatic changes in the Han and Wei Dynasties

“Ya Su Tong fifteen initial consonant” is called as “Zhuo Shang Gui Xia Qu” not “Xia Shang same with Shang Shang”

《雅俗通十五音》初版于嘉庆二十三年(1818),是漳州东苑谢秀岚编辑的反映当时漳州方言的一本韵书。《雅》声母十五音,五十个字母分八音,八音的称说是:上平声、上上声、上去声、上入声、下平声、下上声、下去声、下入声。在每个字母的下上声都是说"全韵与上上同",实际上是七音(七个声调)。为了论证"下上"是否与"上上"同,本文一方面从五十个字母八音中的下去字逐字考证,得出的结论是非"下上"与"上上"同,而是"下上"归"下去";另方面从早《雅》一百年左右代表福州方言的韵书《戚林八音》的浊上归阳去作为印证,说明罗常培先生、邵荣芬先生、李新魁先生的论述"浊上变去"此语音规律估计到南宋就已遍及全国大多数方言是相吻合的。First edition of "Ya Su Tong fifteen initial consonant" as a rhyming dictionary of Zhang Zhou dialect at that time of Xie Xiulan of Dong Yuan, Zhang Zhou originates from 23 th of Jia Qing year of Qing dynasty(1818). "Ya Su Tong fifteen initial consonant" reveals that initial consonant with fifteen tones and fifty alphabets divides eight tones like Shang Ping tone, Shang Shang tone, Shang Qu tone, Shang Ru tone, Xia Ping tone, Xia Shang tone, Xia Qu tone, Xia Ru tone. Xia Shang tone of each alphabet is called "rhythm same with Shang Shang tone", actually that is seven sounds(seven tones). For demonstrating that whether "Xia Shang" and "Shang Shang" are same or not, this paper demonstrates word by word from eight sounds of fifty alphabets to make a conclusion of that "Xia Shang" is not same with "Shang Shang" but"Xia Shang" returns to "Xia Qu". From rhyming dictionary "Qi Lin Ba Yin" represented Fu Zhou "Ya Su Tong fifteen initial consonant" dialect before around 100 years, the discussion of Luo Changpei, Shao Rongfen and Li Xinkui are revealed that voice rules of voiced rising tone are wide spread over nationwide same with almost dialects in Song dynasty

The Origin＇ Value and Deficiency of Ya Su Tong Fifteen Initial Consonants

《汇集雅俗通十五音》是一部两百年前的漳州话字书。《雅》保留了上古和中古的许多语音特点,韵部代表字绝大部份采用见母字,五言顺口又好记。收入的12329字中,有一些是音准义同的方言本字,对方言研究很有价值。《雅》采用朱墨套印的形式,反映漳州方言的文白异读,为研究语音的不同历史层次提供了宝贵的材料。在声调的处理上,作者在每个字母的下上声都说＂全韵与上上同＂,这是错误的,我们从五十个字母八音中的下去字逐字考证后,其结论,非＂下上与上上同＂,而是＂浊上归下去＂。从漳州音系构拟上,我们从韵书中发现某些字音受邻近方言的影响,这些字音为方言间异同提供共时的语音比较,从而说明了语言交际接触中的横向渗透作用。Ya Su Tong Fifteen Initial Consonants was a book of Zhangzhou dialect two hundred years ago（hereinafter Ya for short）. Ya keeps many phonetic characteristics in ancient and medieval times. Most part of the use of rhyme class is derived from initial characters while the five-character is read smoothly and easy to remember. In its 12329 words, some are root words with identical sound and meaning of dialect which are valuable to the research of dialect. Ya takes the form of overprinting in red and black ink, reflecting the literary and colloquial readings of Zhangzhou dialect, which provides precious materials for the phone of different historical levels. In the process of tone, the author claimed full-rhyme being same with Shang Shang about Shang Xia tone of each letter, which is wrong. After the research of Xia Qu character from eight tones of fifty letters, it comes to the conclusion of Zhu Shang returning to Xia Qu, not Xia Shang and Shang Shang being same. From the sound system of Zhangzhou, we find from the rhyming dictionary that some character pronunciation would be affected by the neighboring dialects. And the character pronunciation, offering a synchronic phonetic comparison between different dialects, shows the lateral interference of language communication
