In this paper , the influence of nylon poy storage time on fiber properties such as water content and oil content , cohesion , friction , appearance of oil membrane and antistatic property were discussed 摘要研究了存放时间对绵纶poy纤维含水率、含油率、抱合性、磨擦特性、油膜状态以及抗静电性等性能的影响。
From this viewpoint , this thesis sought to provide a comprehensive explanation for lung ' s consideration toward the community , idealism of literature and art , and idealism of cultural reformation during the early stage of postwar period 本文尝试由此观点对战后初期龙瑛宗的社会关怀、文艺理念、文化改造理想，提出统合性的解释。
While mianchi county and xin ' an county are special , most of villages and towns " economic base are weak , but the increments of per capita net income of rural residents are very quickly 而渑池县和新安县比较特别，大部分乡镇基础薄弱但收入增长很快。伊洛河流域经济的空间特征与其地貌、自然资源、交通设施和农村工业的发展具有很强的空间祸合性。
The basin was undergone multi - period of tectonic movement such as hercyniann indo - chinav yanshanian and himalayan . sangtanghu basin is a superimpose basin which deposited terrestrial sediments of mesozoic cenozoic and has a complicated structural evolutionary history 盆地经历海西、印支、燕山、喜山多期次构造运动，是一个以中新生代为主体的经历了复杂演化历史的叠合性盆地。
We began our investigation of various conceptions of legitimacy with the working hypothesis that these would be “ competing conceptions , ” i . e . , that only one of these theories of legitimacy could be correct for a given domain of application 当我们探讨正当性的诸多概念之始，我们就假设存在“正当性”的诸多“竞合性观念” ，也就是说，在一个给定的运用这一概念的语境之内只有一个适切的正当性概念。
Firstly , it is pointed out that the subject of equity contribution is constrained by the general provisions to shareholders , and therefore retains the rights of disposition , close personal relationship and private nature , which restricts the subject to a certain scope 首先,笔者提出股权出资主体受公司法对股东一般要求的约束,股权出资主体应对出资股权享有支配权,股权出资主体应具备人合性和非公众性,把股权出资主体限定在一定的范围之内。
E . e . enochs put forword the concepts of injective ( projective or flat ) ( pre ) cover and ( pre ) envelope in the early 1980s " , a lot of articles have studied existence and uniqueness of such ( pre ) covers and ( pre ) envelopes , the property of their kernels or cokernels , and character many special rings . moreover , if such kind of ( pre ) covers or ( pre ) envelopes exist , we can construct a complete injective ( projective or flat ) resolvent ( called resolution when exact ) and a partial injective ( projective or flat ) resolvent , and if r is a ring , we can study the relationship of its left global dimension l . d ( r ) ( or its weak dimension w ( r ) ) and the properties of syzygies ( or cosyzygies ) of a resolvent ( or resolution ) , and the relationship of its left global dimension l . d ( r ) ( or its weak dimension ) and the exactness of a resolvent ( or resolution ) 自八十年代初e . e . enochs首次提出并研究内射(投射、平坦) (预)盖及内射(投射、平坦) (预)包这些概念以来，大批论文研究此类包、盖的存在性、唯一性问题以及它们的核、上核的性质，并据此刻画了一些常见的特殊环；更进一步地，当此类包、盖存在时，我们可构造相应的完全投射(平坦、内射)预解式(当正合时称为完全分解式)以及单边投射(平坦、内射)预解式，研究了环的左(右)总体维数、弱维数与此类分解式的合冲模(或上合冲模)的性质、复形正合性之间的关系。
This paper introduces the status of development of polylaticmacid fibre and the main properties of polylaticmacid fibre , and discusses the key measures to produce polylaticmacid fabric to improve its spinnablity and control dyeing technology parameters during the processes of its spinning and finish 摘要分析了聚乳酸纤维产品的研究开发现状，介绍了聚乳酸纤维的生产及性能，结合纤维性能的特点，总结出开发服用聚乳酸纤维产品的工艺要点在于：纺纱中要提高纱线的抱合性，染整中应选择合适的染料及严格控制温度。
