Weft distribution pattern and its input of fabric with varied weft density ;2. In ordor to weave the varied weft density fabric of which weft distribution pattern is prescribed in sections,the definition field of fabric′s weft density function is divided into continuous and discrete intervals according to the variation characteristics of weft density of fabric.

为织造出分区段设定纬密变化的疏密纬织物，根据织物的纬密变化特点，把织物纬密函数的定义域分成连续区间和离散区间；在此基础上，对于分段连续且可能存在间断点的连续区间，建立了卷取量方程；分析并确定了织物各纬卷取量的解区间，给出了卷取量的求解方法——以解区间足够小为解判据的二分法，并阐明了求解方法在间断点处的有效性；对于由离散点构成的离散区间，给出了区间端点卷取量的取值方法和区间中各纬卷取量的确定方法。

One of the important tasks in my dissertation is to investigate Fraunhofer diffraction pattern of a polychromatic, spatially coherent wave diffracted by an annular aperture. The phenomena of spectral anomalies in the vicinity of the Airy rings in Fraunhofer diffraction pattern are investigated in detail. The effect of the parameters of the annular aperture on the spectral changes is studied particularly.

本学位论文的一部分内容进一步研究了在夫琅和费衍射模型下，多色空间相干光经过环形光阑衍射后的光谱变化情况，详细讨论了在该模型下振幅为零的点附近的光谱奇异现象，着重研究了改变环形光阑参数等对光谱变化的影响。

The hot spot leads to the existence of calcium sulfate hemihydrate, which belongs to microwave special effect, rather that non-thermal effect. Second, based on the reaction to get calcium sulphate, we started and ended at the same temperature and then studied through experiment the difference of weight of calcium sulfate obtained through microwave heating and traditional water bath.

第二，基于硫酸钙晶体生成反应，实验研究了微波加热和水浴加热下从相同的初始温度加热到相同的末温生成硫酸钙晶体质量的差异；通过光纤温度计记录了加热过程中两种溶液中心点的温度变化，按照温度变化曲线，通过理论计算了不同的升温速率下微波加热和水浴加热下生成硫酸钙晶体的质量。

Studies show that multifractal spectra of log data are rarely symmetrical, but have steepened slopes on their left branches where the singularity strengths are higher. This indicates more rapid variations in fractal dimensions for highly singular data points in the data series.

研究表明实测的测井数据的多重分形谱很少是对称的，一般是左侧奇异值小的分支比右侧奇异值大的分支的斜率要大，显示了较奇异的点的分数维随着奇异值的变化而有较快的变化。

Rats of model groups were injected with horseradish peroxidase as an indicator of BBB function and compared with control group.

采用HE染色法、辣根过氧化物酶染色法及免疫组织化学染色法观察正常对照组及模型组各个时间点(3、24、48h、3d、1和2周)海马区锥体细胞的变化、血脑屏障的变化及脑组织MMP-9的表达。

In particular, the system generates bifurcation when 2c-a=0, and then the stable knot bifurcates a hyperbolic saddle point and stable convergence, which is so-called Pitchfork bifurcation. From 2c-a≤0 to 2c-a≥0, the attracting set A of the system is changed from single point to the union set of two different old orbits.

系统在2c-a=0时产生分岔，其稳定的结点分岔出一双曲鞍点和两个稳定的汇，这就是Pitchfork分岔，可见在2c-a≤0变化到2c-a≥0时，吸引集A从单点集变成为连接P和P的两异宿轨道的并。

The relationship between the reflectivity and the position of stress is hyperbolic tangent. Moreover, the phase had certain relations. Based on this, the characteristic of FBG under inhomogeneous transverse force were studied.

同时，应用传输矩阵的方法对光纤光栅横向局部受力特性进行了研究，研究发现当光栅局部受力时，反射谱产生分裂，分裂点波长移动与受力大小成线性周期变化，分裂点的反射率与光栅局部受力位置为双曲正切关系，而且相位也存在一定的关系。

Auto-configuration and management of the system node on the base of communication has been implemented in the subject. On one hand, self-management of the system has been figured out. Not only variety in I/O ports but in bus nodes or modules, as long as keeping the data in the system configuration database in accordance with the physical conjunction, the software and hardware of the system need not to be calibrated by the operators.

本课题在实现通讯的基础上，实现了对系统节点的自动配置和管理，一方面实现了系统的自我管理，无论是IO点的变化还是总线节点、模块的变化，只要保持系统配置数据库中的数据与物理连接相一致，系统的软、硬件无需人为改动。

The zero-sequence current will change when the inductance of arc-suppression coil is changed.

该方法通过改变消弧线圈电抗值，从而引起线路上各点的零序电流模值发生变化，根据零序电流模值的变化特性来判断故障位置。

Firstly,the generic conception of symmetry for a real sequence was proposed,and then,the symmetry-decomposition and the symmetric degree sequence are presented,which are deduced from the projection theory,the orthogonal-decomposition theory in inner product space and .

首先提出序列信号一般意义下的对称概念，然后由内积空间中的投影、正交分解理论以及内积量化两个信号线性相关程度的特性导出任意信号的对称分解及对称程度序列，对称程度序列定量刻画了信号随对称点的变化时对称特性的变化，在此基础上得出任意序列信号对称程度的定量指标——对称性指标。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
