休闲阅览室的建设

面对大量读者迫切的休闲需求，本文结合图书馆的实际，在一定实践经验的基础上，就为何要专设休闲阅览室和如何建设、管理好休闲阅览室等进行大胆深入的探讨。     

生物质液化燃油的可利用性及转化技术

随着我国经济的飞速发展,特别是汽车工业的发展,石油资源的短缺逐渐成为制约经济持续发展的瓶颈。积极探索能够替代石油的能源及其生产技术必将具有深远的意义。我国地域辽阔,生物质资源丰富,但是其利用率却很低。为此,提出了生物质转化技术—热解的改进方法,其关键点在于能有效地从生物质中提炼出特性较好的生物质油,产物经适当处理后可作为内燃机燃料。

A MIMD PARALLEL ALGORITHM TO SOLVE TRIDIAGONAL TOEPLITZ LINEAR EQUATIONS

The rank one updating formula and the parallel eliminating algorithm for linear recurrence systems ane combined fo form a MTMD parallel algorithm fo solve tridiagonal Toeplitz Cinear equations. This algorithm has a simple strictire and requires onlty a few storages as well as in-terprocessor communications. There is no special demand on the number of processors in the parallel system. The speedup can come dose to p12 comparing with the LU decomposition method (p is the number of processors). It is worth pointing out that it is proposed algcmthn that considels and organizes the parallel arithmetic in the first order linear ricurrence systems with constant coefficients.     

Research on a Novel Inverter of VSC

In order to improve waveform performance of light HVDC system, a lot of switches which operate in high frequency are used, which causes large switching losses and results high cost. A new Buck type voltage source converter(BVSC) is proposed. The new BVSC comprises a dual-buck converter and a three-phase inverter operating in grid frequency. Only two high frequency switches are used, which results good output waveform performance. In order to reduce the high frequency switching losses, a novel improved double-frequency Buck type voltage source converter(DBVSC) is also proposed. An additional dual-Buck converter is added to the BVSC, the added dual-Buck converter deals with the fundamental power that operates in low frequency, and BVSC only deals with harmonic power that operates in high frequency. The output waveform is enhanced and the switching losses are reduced in DBVSC, and the power rating is also increased. The DBVSC is very suitable for large power rating application. The one cycle control theory is adopted to control the proposed DBVSC with analog circuit, which is very simple. The proposed DBVSC and control method are verified by simulation.     

CASE REPORT: Corneal papilloma associated with papillomavirus in a one‐humped camel (Camelus dromedarius)

A 15‐year‐old male dromedary camel with a history of chronic severe keratoconjunctivitis and corneal mass in the left eye of 6 months’ duration was referred to the Veterinary Medical Teaching Hospital at Adnan Menderes University. A superficial keratectomy was performed and biopsy material submitted for histopathology. The diagnosis was corneal papilloma. There has been no recurrence of the neoplasm to date (6 months, 1 year). Corneal papilloma has not been reported previously in camels and seems to be associated with papillomavirus.     

Development and promotion of laborsaving application technology for paddy herbicides in Japan

Total labor time on paddy rice has been decreasing year by year with the development and introduction of appropriate herbicides, especially ‘one‐shot' herbicides. However, in the case of application of granules, it is still difficult for a farmer to apply herbicides while carrying heavy power backpack sprayers. New formulation recipes and different application technology such as a throw‐in type formulation on jumbo granules or flowable has improved heavy workloads in comparison with granule application by using heavy power backpack sprayers. In addition, other advantageous points such as application volume and elimination of the drift problems of this new application technology were introduced and confirmed. As a result of this introduction, these formulations were used in 830 000 ha and reached 30% of the total treatment area in paddy rice in 2000.     

《道德经》之一分为三哲学思想研究

在《道德经》中 ,老子运用一分为三的思维方式 ,围绕着“道”这一中心概念的逐步展开 ,构建了充满着辩证法的哲学体系 ,成为中华文化的奇丽瑰宝。论述了“道”为“一”、为“无”、为“无为”、为“自然”的一分为三的哲学内涵 ;“自然”为老子哲学体系的开端 ;“道”的“万物得一以生”、“反者道之动”、“物壮则老”、凡事“守中”的一分为三的作用和意义 ;求“道”的一分为三的过程 ;并以此讨论宇宙的起源 ,世界的形成 ,事物的产生、变化和发展的规律 ,以及人类社会的种种矛盾及其解决的方式 ;还讨论了黑格尔对老子一分为
