中弱

Firstly,after the image preprocessing,some features such as axis degree,circularity and central moment are extracted,then BP net is used as weak study machine,and integrate historical information into successive boosting learning.

预处理棉纤维的横截面图，把体现棉纤维的特征的指标从纤维横截面图像中提取出来；然后利用训练好的BP网络作为弱学习算法，使用每一个Boosting分类器学习的历史信息，基于线性回归特征消除策略，消除冗余，据此判别一幅纤维截面图像是否为棉纤维截面图像。

I also have a good friend, called night-blooming cereus, is a Wenruo girl looking for friends in a game I Qianzhu her little hand, so we became good friends.

我也有一个好朋友，叫昙花，是一个文弱的女孩，在一次找朋友的游戏中我牵住了她的小手，于是我们成了好朋友。

The results indicate that improving temperature to reflux, using low polarity solvent as dispersion medium and proper molar ratio of tetrabutyl titanate to stearic acid can bring out good modification. The function of tetrabutyl titanate is to react with the surface hydroxyl groups and adsorbed H2O on the powder particles to produce new binding sites such as M—O—Ti—OC4H9and M—O—Ti—OH, which can easily react with the carboxylic acid. As temperature increases from room temperature to reflux temperature, the reactions between RCOO- and Ti change from coordinate bonds to covalent bonds, which makes the carbon chains of stearic acids more strongly bound with the powder particles surface.

研究结果表明，提高处理温度、适当增加复合改性剂中硬脂酸的量并选用极性弱的有机溶剂可达到比较理想的改性效果；钛酸四丁酯的作用是与粉体粒子表面的羟基以及吸附水反应产生偶联点，如M—O—Ti—OH，这些偶联点易于与羧酸反应；在低温时RCOO-与偶联点的Ti之间以配合物的形式发生作用，在回流温度下处理时，主要发生酯化反应，使硬脂酸更牢固地嫁接到粉体粒子表面，改性效果更好。

Objective To study the interaction of bile salts, namely sodium taurocholate, sodium tauroglycocholate, sodium deoxycholate and cow sodium cholate, with Cu2+ in acetic acidsodium acetate buffer.

目的 研究弱酸性介质中，牛磺胆酸钠、甘牛胆酸钠、胆酸钠和脱氧胆酸钠等4种胆酸盐与Cu2+离子相互作用。

The experimental result shows that, when 200～400 g/t hydroxylapatite adsorbent is used and the stirring time is longer than 60 minutes at normal temperature, the mass density of Pb 2+ in chrome yellow wastewater is reduced to lower than 0.5 mg/L, which comes up to the standard of industrial drain water (1.0 mg/L).

羟基磷灰石吸附剂对铬黄废水中Pb2 +吸附的间歇实验结果表明：当每吨废水中吸附剂用量为 2 0 0～ 4 0 0g时，常温搅拌 6 0min后，在弱酸性或中性废水中，铅离子质量浓度由2 。74mg/L降至 0 。5mg/L以下，完全符合GB8978- 1996工业废水排放标准 1.0mg/L。

There exist diffrenent weak interactions in the clathrate complexation.

得到的笼形包合物中存在不同的弱相互作用。

For soft clays, the initial rate of ground settlement is faster than that in clayey soil.

在凝聚性土层中开挖隧道，随土层强度越弱，初使沉陷速率越快。

Schauengurg[2] considered more general case and found necessary and sufficient conditions for the cosmash product coalgebra H Q to be a Hopf algebra with a Hopf subalgebra H and a weak projection !

Schauenburg在文献[2]中把Radford的研究加以推广，给出了使余smash积HQ为Hopf代数，H为HQ的子Hopf代数，且具有弱投射π：HQ→H(即π是左模余代数同态，且π|_H=id_H)的等价条件。

Recently many of statisticians have been interested in the functional coefficient model because of its simplifying structure, meaningful interpretation and wide application. In the chapter 2, estimators of parameters of linear functional coefficient structural model under interval-censored covariate studied.

由于协变量区间删失，为此我们创立了一个与协变量具有相同均值的变量，然后利用加权最小二乘估计法得到了变系数一维线性结构关系模型中的参数估计，当协变量的分布已知时，证明了估计的弱相合性和强相合性。

And there is a descend trend of herd behavior in 2006, whats more, the herd behavior in the trade industry and colligate industry are more obvious than others.

在对我国股市进行分段研究时，发现比起我国早期股市在2006年羊群行为有减弱的趋势，而在对我国不同行业羊群行为的检验中，发现房地产类股票的羊群行为相对较弱，而批发零售类和综合类的上市公司羊群行为较为显著。
