The experimental result is discussed in detail and it is proved that the nitro group in raw material cannot be reduced into amino group entirely.

在对实验结果作了详细的讨论后得出结论：在这一反应中，反应物中的硝基并没有被彻底还原为氨

And therefore it avoided the phenomena that makes waster ratio to be higher caused by overhigh or lower temperature.

文中讨论台达温度控控器在塑料加工生产过程中的具体应用，以保证在复杂生产环境中精确地控制原料生产温度，避免温度过高或者过低造成废品率高的现象。

He researched the imprison on the background of the discussion of normal modern (the discipline which has been applied in school 、 factory 、 hospital ,and army),and explained the way by which the Panopticon was used as the pattern and corn of the whole series practice discipline.

他在一般的现代规范化训练实践(作为在学校、工厂、医院、军队中应用的训练实践)背景中讨论了监禁，而且说明了"圆形监狱"是如何被用作这一完整系列的训练实践的模式和核心的。

Secondly, the paper does research systematically on the basic theories of MDA, including MDA model architecture, Meta Object Facility, the mapping from metamodel to other formats and Common Warehouse Metamodel. The paper also analyzes detaily the definition, the basic rule and the characteristic of model transformation. Then a standard development flow based on MDA is put forward. The problems about parameterized mapping and partial round-trip engineering are discussed. From the discussion the most optimized method is pointed out.

其次，本文系统深入地研究了 MDA 建模体系、元对象设施 MOF、基于 MOF 的元模型到各种信息格式的映射和公共仓库元模型 CWM 等 MDA 基本理论，分析了模型转换定义、规则及其特征，提出了一个基于 MDA 的开发流程，讨论了在模型转换过程中的"参数化"映射问题和"往返工程"问题，并在多种解决方法中分析出最优解决方法。

The formation mechanism of the screw structures on the surfaces of polytype crystals is discussed according to the theoretical model of anionic coordination polyhedron growth units.

本文用负离子配位多面体生长基元理论模型讨论了多型性晶体表面螺旋结构的形成，提出在多型性晶体中配位多面体呈层状分布，配位多面体的面为层的边界，上、下层负离子配位多面体不是呈镜象对称的，在三方晶系和六方晶系的晶体中是沿晶轴a、b错开，上、下两层负离子配位多面体体呈交叉对应，从而达到稳定平衡。

In this article firstly some aspects which impact on market and preconcert will be investigated respectively; then some discussions are carried through on how important project schema is towards project result; finally respective emphases on project schema of market and preconcert development are concluded.

为了实现这个目标首先运用一个定量的手段分析在面向市场软件开发和定制软件开发中影响成功的元素；接着运用定性的手段讨论项目计划和项目结果的关系；最后得出为了取得软件项目的成功，在面向市场的开发和定制的开发中，做软件项目计划时各自需要重视和强调的部分。

The 1-generator quasi-cyclic codes and their duals are the most frequently encountered QC codes in the literature. Séguin discusses the construction and the enumeration of 1-generator QC codes in the special case where the prime factorization of x~m — 1 is the same in IF_qn as in IF_q.

单生成元的拟循环码及其对偶码是拟循环码中研究最多的一种。Séguin在要求x~m-1在F_q及F_中具有相同的分解的条件下，讨论了单生成元的拟循环码的结构及计数。

Some research and analysis on the reaction of 2,4-difluoronitrobenzene and nucleophilic reagent alcohol sodium (methyl alcohol ,ethyl alcohol, propyl alcohol, n-butyl alcohol, t-butyl alcohol, et hl) and the reaction choice of opposite -F in different solvent and conditions have done in this paper.

论文以2，4-二氟硝基苯为主要原料，研究了其与亲核试剂醇钠(甲醇、乙醇、丙醇、正丁醇、叔丁醇等)在不同溶剂中的反应情况，讨论了在几种代表性的溶剂——醇、四氢呋喃、苯、N，N-二甲基甲酰胺中亲核取代反应的情况，研究了温度、反应时间、亲核试剂、溶剂等条件对亲核取代反应的影响。

In the elaboration process, mainly introduced the changing about taotiedesign and bird line status relations with transformation shang and zhou dynasty, andnoted the step difference which the cultural transformation and the society transformedto cause early zhou time the still to save the Yin person style; and appearing qiequ lineshas ended taotie design mysterious and norm, has guided it that the style of ritualbronze imagery liberates. Paying attention to heng S shape being put into use commonlyin design and model, suggesting that qiequ lines originates from taotie design, bird linesand xiang bilong lines is the formative technology need.

在论述过程中，主要讨论了饕餮纹与鸟纹的主体地位转化与商周社会转换关系，文化变革与社会变革的步伐差异导致周初青铜纹饰仍存殷人气息；窃曲纹的出现结束了饕餮纹的神秘与规范，引领了青铜器纹饰自由解放的气息，并注意到横S形在纹饰造型中的普遍使用，从而提出窃曲纹来源于饕餮纹、鸟纹的分尾与象鼻龙纹的应用更有可能是造型工艺的需要。
