With respect to syntax, the roles of tagmeme in the structure of word and sentence and Chomsky's Generative-Transformational Grammar are discussed. The spatial relation theory and existing research achievements are investigated. Having noticed the shortage of the capability of topological and metrical relation in the description of spatial information structure, the author proposes Combinational Qualitative Geometry based on the two invariables under ordinary transformations, distance ratio and direction difference, the CQG-based spatial relation system between topological and metrical constraint is thus constructed, on which several spatial relations such as parallel, perpendicularity, co-linearity, sequence and direct neighborhood are derived. Based on extended theory of spatial relation, the language anamorphosis is analyzed from the aspects of phonetics, semantics and syntax. The mere geometric and formalized spatial relation is then integrated with concrete geographic ontology to accommodate richer and indicative spatial configuration of spatial information in the different geographic context. Finally a syntax framework for spatial information is put forward.

在语法结构方面，首先阐述了法位和法素在语法结构词法和句法中的地位和作用，以及Chomsky生成转换语法的核心内容；详细介绍了地理信息系统空间关系理论及现有的研究成果；在分析现有的拓扑关系和量度关系对空间信息结构描述能力不足的基础上，提出了基于长度比和角度差两个不变量的组合定性几何，以此建立了介于拓扑及量度约束之间的组合定性关系体系，并以此为基础派生出平行、垂直、共线、次序、直接邻近等空间关系描述；本文基于扩展的空间关系理论，详细讨论了空间关系在语音、语法和语义三个方面的语言变体，将纯几何和纯形式化的空间关系与具体的地理本体结合起来，可以获得更为丰富的、更能反映空间关系在不同语言上下文中具体体现的组合关系；最后给出了一个空间信息的语法结构的基本框架。

objective to investigate the clinical therapeutic effect of mucosolvan nebulization in infants with pneumonia.methods 96 infants were randomly divided into and control group.regular treatment were given to control group,meanwhile,based on regular treatment,the infants in observation group were also received mushutan nebulization.the disappearing time of cough、wheezy phlegm、anhelation、wheezy sound in lung and admission duration were evatated.results the disappearing time of wheezy phlegm、wheezy sound in lung and admission duration in observation group were shorten than in control group(p.05).conclusion mucosolvan nebulization can raise clinical therapeutic effect for pneumonia in infants with pneumonia.especially in eliminating phlegm and disappearing of wheezy sound in lung.

摘要］ 目的：为探讨沐舒坦雾化吸入辅助治疗婴幼儿肺炎的效果。方法：将96例婴幼儿肺炎随机分成两组，两组均在常规抗感染，纠正缺氧、酸碱平衡、电解质紊乱，治疗组加用沐舒坦雾化吸入，对照组用α糜蛋白酶、地塞米松雾化吸入。对两组的咳嗽、痰鸣、气促、肺部湿音的消失时间及住院时间进行比较。结果：使用沐舒坦雾化吸入的治疗组在治疗痰鸣、肺部湿音消失时间及住院时间比对照组短（p.05）。结论：沐舒坦雾化吸入可提高婴幼儿肺炎治疗效果，尤其祛痰和减少肺部湿性音的效果较好。

In this study, we isolate, purify and characterize endo-β-glucanase by Ascomycete Xylaria regalis. The cellulose-containing medium is used to induce the production of the cellulose-degrading enzymes. When these enzymes are produced at maximum level, we harvest and filtrate the culture medium. The filtrate is purified by anion exchanger column and hydrophobic interaction column (phenyl-650M). The purification fold of endo-β- glucanase increases 4.3 times, the specific activity approaches 3.7 unit/mg, and the recovery is 27.6%, respectively.
