用于软件技术支持服务质量评价的量表修正研究

"软件就是服务",软件业的竞争更多地表现在服务质量的竞争.服务质量(SERVQUAL)主要是从顾客的角度进行衡量的,服务质量量表是顾客感知服务质量评价领域应用得最广泛的量表,也是服务质量评价的重要标准,但这个量表在具体应用中仍存在一定的局限.本文基于Sun的VIA项目对SERVQUAL量表进行实证检验,最后提出修正方案.     

被复线故障检测仪的研制

本文介绍的检测装置以89C51单片机为核心，将故障检测和巡线信号有机结合并将两个功能进行了分时引入，可以对任意类型的被复线实现自动校正、自动测量和智能分析故障类型以及在很小强度人为干预下实现故障的定位。该仪器能对同线的多处故障自动顺序检测以及具有较强的抗干扰能力和较宽的工作电压范围。     

穗花柊叶属(竹芋科)植物增补

The present paper reports the first record of the eGnus Stachyphryni- um, Marantaceae, in China.  It is characterized by solitary spikes, elongated and erect with impricated bracts.  The inflorescence arises from a short stem on the rhizome.       In this genus there are 14 species in total.  They are distributed from Sri Lanke to Java and Borneo, through Indo-China Peninsula, Malay Pennisula.  Its distribution center is in Indo-China Penninsula and Malay Penninsula.  The north limit lies in sou- thern Yunnan of China. Most species of the genus have a stenochorie area, for example, S. zeylanicum is endemic to Sri Lanka; S. latifolium occurs in Java only and so on.      A New species, S. Sinense H. Li, to China, is illustrated and described in Latin.     

中国兜被兰属植物的研究

兰科的兜被兰属约有12种，主要分布于亚洲的温带至亚热带山地，我国的四川和云南是其现代分布中心和分化中心。本文通过植物地理学、孢粉学和解剖学的研究，对该属进行分类学订正，确认中国产有12种，其中9种为我国特有，包括4个新种和1个新组合种。     

苍山蕨属的研究

eterachopsis was proposed by the senior author as an independent genus of the family Aspleniaceae in 1940 with 2 species.  Since then much study on its morpho- logy,  anatomy,  gametophyte and palynology has been carried out by Nayar,  Bir,  Chan- dra & Nayar and Chang et al.,  and they are of the opinion that the genus like Ceterach, is a comparatively primitive element in the family Aspleniaceae.  The queer zigzag pa- tern of cutting of lanceolate fronds appears extraordinary in the family Aspleniaceae, and also suggests its antiquity in evolution. So far only 3 species  (C.  dalhousiae,  C. paucivenosa and C. magnifica) are recognized,  the former from W. Himalayas,  also known from Africa,  while the latter two from W. S. China (Yunnan).  However,  in the past forty years the Chinese botanists have discovered 2 more species as new in N. W. Yunnan,  thus bringing the total known species of the genus up to 5.  The present paper is a brief summary on the genus Ceterachopsis,  which will be published in detail in the Flora Sinica vol. 4.       Pteridologists are also divided in their views regarding the generic status of Cete- rachopsis with 5 well-defined species in Yunnan and the East Himalayas.  We prefer to mintain it as a genus separate from Asplenium on account of its distinct morpholo- gical features.  It is to be hoped that more species may come to light in the mountainsin N. W. Yunnan through further exploration now under way.     

海桑属的新分类群

Sonneratia, a small genus of Sonneratiaceae, is widely distributed throughout SE. Asia, E. Africa and N. Australia, extending from 18˚S. to 20˚N. and from 45˚ to 150˚E. In China it occurs only in the Hainan Island. In this paper,  two new sections areproposed and six species are recognized, of which one is described as new.
