可取代的

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。

The results indicated that:(1) It is viable to use the electron affinity energy of the metal atom in the catalyst, and the ortho-/para-substition ratio of phenolic model compounds as parameters. Thereby, the related data of Resole resins catalyzed by different catalysts can be put into the same training set for modelling.

研究结果表明：（1）用催化剂中金属原子的电子亲合能和酚醛模型化合物的邻／对位取代比作为特征参数是可行的，因而可将不同类型催化剂催化的Resole树脂的有关数据合并于同一训练集中进行建模。

Therefore esterification crosslinked reactionbetween polyearboxylic acid and wood can be quantitatively determined.According toexperiment results of stereoscopic configuration choices by crosslinking agents,crosslinkingreaction between model of reaction intermediate and wood,and the intermediate characteristic incrosslinking reaction,crosslinking reaction intermediate was proofed.We can infercrosslinking reactions between polycarboxylicacid and wood want through a mechanism of twosteps reaction process,the first cyclic anhydrides were formed as intermediates by dehydratingbetween hydroxyls in polycarboxylic acids,second esters were occurred by substitution reactionbetween wood hydroxyls and cyclic anhydrides.

从而可全面定量表征木材与多元羧酸类化合物的酯化交联反应；依据交联剂立体构型选择性、反应中间体模型物与木材的交联反应和交联反应中间体的波谱特征实验结果，证实了交联反应中间体，因此可以推测：多元羧酸类化合物与木材化学组分的交联反应是经历两步反应的机理，首先多元羧酸中相邻羧基的羟基之间脱水形成五元环酸酐中间体，然后木材的羟基与酸酐发生亲核取代反应形成酯。

Ffering an exceptional range of industry-standard options and innovating no less than three unique functions, the Oxy replaces the acclaimed Servomex 1900 to set new standards of performance from a single, cost-effective unit.

xy产品可提供广泛的工业标准选项且新开发了至少三项独一无二的功能，因此取代了曾倍受赞誉的仕富梅1900，以其一体化、经济的装置设立了新的性能标准。

However, the reason that LCD can't fully take the place of the tube is mainly on the performance of color and motion image. Though LCD can greatly improve the Color Saturation up to NTSC 105%, LCD is limited on reaction time and continue LCD light source, which create image shape shadows while the image moves due to photogene.

而液晶显示器目前无法完全取代映像管的地方就在於色彩及动态影像的表现，虽然发光二极体已可大大改善色彩饱和度到达NTSC 105%，但液晶显示器受限於液晶的反应时间及液晶显示光源表现为持续方式，使在动态影像表现上因人眼的视觉停留的因素导致影像移动的边界上产生阴影。

Putting DuPont's polymer science and biotechnology together with Plantic's leading-edge starch-based technology helps both companies broaden the performance of this class of polymers, while accelerating the availability of more options to replace the use of nonrenewable feedstocks,' Shanna Moore, DuPont global business director for sustainable packaging materials, said.

把杜邦公司的聚合物科学和生物技术一起Plantic领先的淀粉基技术有助于扩大两家公司的业绩这一级别的聚合物，同时加速提供更多的选择，以取代利用不可再生原料，莎娜摩尔，杜邦公司的全球业务总监为可持续包装材料，说。

In this double-blind study, 142 women with high-risk singleton pregnancies received 100 mg progesterone or placebo daily by vaginal suppository. Between 24 and 34 weeks of gestation, all subjects had uterine contraction monitoring with an external tocodynamometer once weekly for 60 minutes.

对早产的高危险孕妇来说，预防性地在阴道使用progesterone可降低子宫收缩的频率，并减少早产的发生，虽然目前我们还不清楚它的作用机转为何，但我们知道它对子宫肌肉层有2种作用：一为藉由抑制细胞质内动情素受体的取代而抑制动情素发挥作用，另一个则是经由它自身的细胞性受体而直接作用在子宫的生合成路径上。

The principle of "reasonable domesticating method", which does not stand for expressing the source-language message in the complete form of a target language, but, if necessary, the use of "dissimilating method" to reproduce the original message in a foreign style,is just the internal embodiment

摘 要：&合理归化&原则是文学翻译标准绝对性与相对性的内在体现，它不主张用目的语的表达形式去完全取代源语的表达形式，必要时还可采用&异化&手法保留源语的表现特色，再现源语的文化信息。

Our field experiments show that observation of cuckoo mobbing by neighbors on adjacent territories induced reed warblers to increase the mobbing of cuckoos but not of parrots on their own territory.

新的研究显示，这些苇莺可通过观察它们的邻居而学习这种行为，但这种过程是受到生物学支配的–当研究人员用一种无害的假的鹦鹉来取代布谷鸟的话，则这些苇莺就不会学到这种技能。

Caldara was to find musical practices in Rome to be very different to those of his native Venice. 11 As a result of a papal ban on public opera performance private oratorios and semi – private performance replaced public opera and the grand spectacles of public worship at San Marco.

卡尔达拉是找到在罗马音乐的做法非常不同，他的家乡威尼斯的。11作为对公众的演出私人圣乐和半教皇禁令的结果-私人性能取代公共歌剧和圣公众礼拜大眼镜马可。
