类化

We define two kinds of reducible Dirac structures, discuss the problem on the reduction of protobialgebroids.

我们定义了两类可约的Dirac结构，讨论了proto双代数胚的约化问题。

For getting the major characteristic edges without confusions by undesired structures like muscle edges, we integrate a star-like edge detection filter named "Asterisk Filter" with the Canny Edge Detection in the image preprocessing. In addition, we also propose a new contour tracking method named "One-Pixel Rolling Ball Contour Tracking" for getting the boundary information in a binary image which is a link-list data structure. Instead of using a regression curvature estimator, PCA is used for better curvature estimation from a discrete bony contour.

为了从影像上取得骨头特徵边缘，将不重要的肌肉视为杂讯滤除，我们引用一种星形滤波器－Asterisk Filter，搭配Canny边缘检测法，做为这类影像的前处理；另外，为了将骨头的边缘精确地追踪出来，我们提出滚球边界追踪法，来对二值化影像进行边缘追踪，藉此获得边缘的串列资料结构；我们采用以主成分分析(Principle Component Analysis，简称PCA)取代原本以回归方法来计算的曲率，以取得更佳的曲率估测值，其可提高计算之参数的准确性。

It is difficult to distinguish the signal from the noise in the time domain and frequency domain by the regular digital signal processing algorithm.

近年来迅速发展起来的小波变换分析法，具有很强的时频局部化特性和信号特征提取能力，特别适用于局部放电这类脉冲信号的处理。

In this thesis,we discuss the problems of applying regularization methods to solvelinear and nonlinnear operator ...

本文讨论了利用正则化方法求解线性及非线性第一类算子方程的问题。

The scaling relations and the scaling exponents of the relaxation time and order parameter are obtained, which are different from original NaSch model. The top-priority of randomization will lead to synchronized traffic flow and there is criticality in traffic phase transition.

计算结果得到了驰豫时间和序参量的标度关系和标度指数，结果发现与原始交通流NaSch模型不同，优先随机慢化将引起交通同步流，交通相变具有临界性，其标度指数属于确定NaSch模型类。

Phenolic-doped melamine-formaldehyde aerogels were investigated by adding resorcin to MF sol before the formation of crosslink. The solvents in wet gel were then exchanged with ethanol.

以三聚氰胺和甲醛为原料制备MF气凝胶，在凝胶化过程中加入酚类化合物对MF体系进行改性，获得相应的湿凝胶，湿凝胶经超临界干燥，制备出密度为最低可达50 kg·m-3的酚改性MF气凝胶。

Retene, simonellite, pimarene and long side chain indanes were identified in algal pyrolysates for the first time.

首次在藻类热模拟产物中检测到惹烯、西蒙内利烯、海松烯及长侧链二氢化茚类化合物。

The methods of correction of CT images, revertible design and space positioning are studied.

提出了CT图像的伪影校正方法；研究这两类植入体的原位匹配设计技术，特别是空间定位方法的提出，实现了下颌骨2期义齿修复中种植桩的精确定位；利用快速原型结合快速模具技术和精密钛铸造技术实现钛支架和钛体的成型，实现了快速定制化制造。

The asymptotic output tracking is usually not possible because the linearized system has uncontrollable modes whose eigenvalues are on the right half plane.

因为这类系统的线性化系统具有不可控模式且该模式在右半平面内有根，所以全局渐近输出跟踪是不可能的。

You need to initialize the FileUtils class only once to use its members and handle local files robustly.

你只需要对FileUtils类进行一次初始化的工作，就可以开始使用FileUtils的成员，对本地文件进行强有力的操作了。

What would he tell Judith and the children?
