At last,we give the definition of FGT rings which is the extension of cogenerator rings.

在第二章中，我们由FGT -内射模的启发引入了CT -内射模的概念，在这一章我们知道ann -自内射环其实就是CT -内射环，只是ann -自内射环是从零化子的角度来讨论，而CT -内射是从循环无挠模的角度来进行讨论的，同时也给出了一些等价条件。

Methods An unsupervised local and global features extraction method was adopted for the localization of facial features of frontal view face image. First, a threshold was used to segment the image into foreground and background, and the nose was localized by considering the symmetry of the face. Second, Harris operator was adopted to detect interest points in a rectangular area covering all the facial features, and then local maximum of the interest points were detected. And finally, Kmeans clustering method was used to cluster the points and obtain the facial features localization.

针对红外正面脸部图像，采用一种无监督的局部和全局的特征提取方法，首先通过阈值法区分出前景和背景，并根据面部特征对称性在前景中确定鼻区；然后在面部确定一个包含所有特征的矩形区域，利用Harris算子在该区域检测出角点，并找出这些点的局部最大值点；最后用Kmeans方法对这些点进行聚类。

A hypothetical massless,neutral elementary particle believed to mediate the strong interaction that binds quarks together.

胶子假设的无质量的中性基本粒子之一，被认为能传递一种把夸克结合在一起的强大的相互作用力量

It was full of sap, full of leaves, and full of boughs; but now in vain does the busy art of man pretend to vie with nature, by tying that withered bundle of twigs to its sapless trunk; it is now at best but the reverse of what it was, a tree turned upside-down, the branches on the earth, and the root in the air; it is now handled by every dirty wench, condemned to do her drudgery, and, by a capricious kind of fate, destined to make other things clean, and be nasty itself; at length, worn to the stumps in the service of the maids, it is either thrown out of doors or condemned to the last use - of kindling a fire.

如今变了样，却还有人自作聪明，想靠手艺同大自然竞争，拿来一束枯枝捆在它那已无树液的身上，结果是枉费心机，不过颠倒了它原来的位置，使它枝干朝地，根梢向天，成为一株头冲下的树，归在任何干苦活的婆子的手里使用，从此受命运摆布，把别人打扫干净，自己却落得个又脏又臭，而在女仆们手里折腾多次之后，最后只剩下一支根株了，于是被扔出门外，或者作为引火的柴禾烧掉了。

The sequences of segments of the trnL intron from 29 species and trnL-trnF IGS from 21 species of Magnoliaceae were analyzed. The results from the strict consensus trees were consistent with the former systems ① several species within the genera Michelia were homologious;② the subgenera Yulania was extremely homologious and much far from subgenera Magnolia;③ the species within Manglietia were highly conservative.

通过木兰科29个种的trnL基因内含子的525个碱基序列及21个种的trnL-trnF基因间隔区的370个碱基序列测定和分析，构建的严格一致性树建议：①含笑属为相对一致的单系类群；②玉兰亚属的几个种形成一个单系类群，与木兰亚属的几个种无共衍位点；③木莲属为个相对保守的类群，种间碱基差异很小。

This paper presents a maximum criterion-based phylogeny analysis method for unrooted trees. To increase the confidence level of the derived evolutionary trees, we use bootstrapping and consensus analysis in conjunction with a genetic algorithm for crossover and mutation between evolutionary trees.

本论文采用最大概率字元特徵式的评分方式，以及无根的建构方法，利用基因演算法对所有可能的树的子树做交配与突变，再使用统计自序法与一致演化树法来增加树的可信度。

Separation of the sapindus-saponin from natural sapindus pericarps is very difficult, a rapid and simple determination method for total-sapindus-saponin is not founded.

为解决无患子皂苷分离较困难，无快速简单的检测方法等问题，本研究采用超滤膜分离和泡沫分离等新型分离技术对无患子皂苷进行分离纯化，并采用分光光度法测定无患子总皂苷。

As simple as a feedback loop is, it can be stitched together in endless combinations and forever stacked up until it forms a tower of the most unimaginable complexity and intricacy of subgoals.

就是这么简单的一个反馈回路，却可以在一种无穷尽的整合过程中缝合在一起、永远这么共同工作下去，直到它们形成一个由各种具有着最不可思议的复杂性和难度的子目标所形成的塔。

Tang Mian flesh is meat, add flour in the amount of salt and pepper noodles, hot oil, oil temperature should be moderate, not too high and will prevent the hot flour paste, and the second step is to face a good hot rolled up into a good In the face of the quarter, rolling up flange, a circular made into a special sub-branded over the roast, no smell of fuel used for charcoal, grilled over time continue to Cayou warming, can be cooked.

肉瓤是烫面，在面粉中加入适量的花椒面和食盐，用油烫制，油温要适中，不可过高，防止将面粉烫糊，第二步是将烫好的面裹进醒好的面季中，翻边推擀，做成圆形，放入特制的烙子上翻烤，燃料用无异味的木炭为好，翻烤时不断擦油增温，熟透即可。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
