首先构建便于计算树的零度的树的存储结构，结合树的最大匹配与零度之间的关系，利用C++语言设计并实现可以计算任意树的最大匹配数和零度。

This paper create storage structure of trees to calculate the nullity of trees easily, using relationship of between the max?imum matching number and nullity of trees ,the algorithm is designed and implemented to calculate the the maximum matching number and nullity of any tree by C++language.

借用我国学者王希杰的零度偏离理论，分析英语手机短信语言中的“去元音化”现象，指出“去元音化”是英语短信语言中的另类缩略方式，是对现有缩略语的拼写方式的变异和突破，是对常规缩略法零度的偏离。如何在使用“去元音化”缩减字符数与认知之间找到平衡，有效运用零度偏离理论的方法论原则，最大限度发挥“去元音化”的作用，是我们要进一步探索的课题。

Employing the theoretical framework from the field of rhetoric, the disemvoweling of English short message is analyzed. It argues that the disemvoweling is a particular abbreviation deviation in English short message. It is the breakthrough of the existing abbreviations spelling variation and deviation from conventional abbreviated method. Based on the zero and deviation theory, balancing between the reduction of the number of characters and cognitive effective of disemvoweling is the key for people to realize the disemvoweling.

非真性询问选择疑问句具有陈述性功能、指令性功能和提议性功能,是对真性询问选择疑问句询问性功能的偏离。倘若把非真性询问选择疑问句视为操作的零度,反问式非真性询问选择疑问句、设问式非真性询问选择疑问句和反问式设问非真性询问选择疑问句均是对非真性询问选择疑问句这个操作的零度的偏离。反问式非真性询问选择疑问具有陈述性功能、指令性功能和提议性功能;设问式和反问式设问非真性询问句仅具有陈述性功能。

This paper focuses on the theory of zero deviation and the theory of‘How to do things with words’ proposed by John Langshaw Austin. The alternative questions of non-authentic inquiry are special sentences and are the zero deviation from the alternative questions of authentic inquiry. Statement functions, directive functions and proposal functions are the zero deviation from the inquiry functions. The author has conducted a pragmatic analysis on the alternative questions of non-authentic inquiry in three scenarios and summed up the conditions. The alternative questions of non-authentic inquiry can be divided into itemized alternatives, positive and negative alternatives, specific interrogation alternatives and yes-no interrogation alternatives.

为了分析不同高度回波强度与地面降水的关系,提高雷达定量估测降水的能力,本文对石家庄2006~2008年5~9月共77次降水过程的反射率因子垂直廓线(VPR)进行了统计分析。对比降水实况和VPR发现,各个高度层的反射率因子波峰(谷)同降水波峰(谷)相一致,而且降水强度越大,反射率因子核心高度越低。同时,还比较了距离雷达站不同的水平距离和不同海拔高度的反射率因子特征,发现海拔高度对5 mm/h以下降水率和垂直高度在4 km以下各层的反射率因子会造成一定的影响,而对强降水和高层反射率因子影响较小。另外,零度层亮带在VPR上表现出反射率因子增大的特征,影响降水估测效果。为了消除零度层亮带的影响,选取1.5~3.5 km为估测降水的最佳高度范围,各站具体选取高度则取决于其距雷达站的水平距离和海拔高度。

In order to improve the ability of radar quantitative precipitation estimation (QPE),the relations between ground rainfall and echo reflectivity at different heights were analyzed based on 77 vertical profiles of reflectivity (VPR)during the rainfall processes in summer (May to September)from 2006 to 2008 in Shijiazhuang.By comparison actual rainfall and VPR,the wave peaks/valleys of re-flectivity in each level were consistent with more/less rainfall,and the larger the rainfall intensity,the lower the height of reflectivity core.Furthermore,the characters of reflectivity in different distance from radar station and different altitude were contrasted,in some extent,the altitude can influence the rainfall rate when it was less than 5 mm/h and the reflectivity factor when the vertical height was below 4 km,but little effect on the severe precipitation and the reflectivity factors in higher layers.The precision of QPE was influ-enced by zero-layer bright band because its reflectivity facto

池莉小说改编在今天这个文化转型时期,具有典型意义和样本作用。在审美取向上,她的小说与其改编作品之间均注重对人生经验、庸常琐事的刻画并呈现出相似的日常生活审美化特征;在创作方式上,改编作品将原著的"零度"情感变成了较为煽情的伦理化表达。从文学到影视,相融相通又相异,有得又有失,突出了影视改编对文学取长补短的作用。

In the period of today’s cultural transformation ,Chili’s novels are of typical significance and sample function .In the aesthetic orientation ,both her novels and their adaptations focus on describing life experience and trivial matters and show similar characteristics of the aestheticiza-tion of daily life while in the ways of creation ,the originals’“zero degree”emotion is changed into more sensational ethical expression .Literature and film and television are mutually integrated and different from each other in the meantime .There are gains and loss in the process of screen adap-tation ,which highlights the strong points of literature and offsets its own weaknesses .
