The method obtained multiple training samples from a single face image by multi channel sampling before two-dimensional independent component analysis transformation. Experimental results on the ORL face database and YALE face database show that the proposed method is feasible and has higher recognition performance compared with GREY, PCA, ICA, 2DICA, projection combined PCA, FLDA, sampled FLDA and other algorithms where only one sample image per person is available for training.

该方法是在2DICA运算之前，首先对单训练样本进行采样，通过多频率采样可以获取多个不同频率下的采样样本，然后对采样样本进行2DICA特征提取，最后采用神经网络分类识别，对人脸库ORL和YEL作了相关实验，将该方法与GREY、PCA、ICA、2DICA、PC PCA、FLDA、Sampled FLDA等传统方法作了比较，最终证明了该方法可以有效地解决单训练样本人脸识别的问题。

The marking is applied in the form of indicia, such as a one- or two-dimensional bar code, a matrix code, or the like.

这标记采用的是邮戳形式，例如一维或二维的条码，矩阵码，或其它类似的方法。

The results show that the increase of the surface charge can exhaust the two-dimensional electron gas, and reduce the current collapse effect and saturation current, inducing the abnormal shift of the knee voltage.

研究结果显示表面电荷的增加能够耗尽二维电子气，减弱电流坍塌效应，降低饱和电流，使膝点电压非正常后移。

对全日和半日潮流，本计算给出了一个前人未注意到的圆流点。文章还给出了潮生余水位和余流的分布，并计算了潮能通量。

However, the right ventricule has a crescentric shape, with a separate infundibulum and prominent trabeculations, it is difficult to describe the right ventricule by a simple geometric figure and therefore, difficult to assess its function in a conventional two-dimensional echocardiography.

另 卜，肺动脉高压（Pulmon叼 hypertension，PH）是左向右分流型CHD如ASD常见的并发症之一，PH的存在与否及其严重程度与先心病治疗决策、手术疗效及临床预后密切相关，但先心病合并肺动脉高压的发病机理仍不清楚，尚待进一步研究和探讨。

The unification of inherency and externalism of labor, namely the two-dimensional structure of labor, showing the contradiction of labor itself, that is the basic connotation of labor category in Marx philosophy.

劳动内在性与外在性的统一，即劳动二维结构，显示了劳动自身的矛盾性，是马克思哲学劳动范畴的基本内涵。

It has manifested human\'s natural attribute .The unification of inherency and externalism of labor, namely the two-dimensional structure of labor, showing the contradiction of labor itself, that is the basic connotation of labor category in Marx philosophy.The category of labor which is in the central position in Marx philosophy, is the framework of historical materialism founded by Marx.

马克思哲学的劳动范畴，一方面从人与自然的区别中，认为劳动是人的类本质或自由的有意识的活动，因而，劳动对人来说具有内在性；另一方面从人与自然的联系中，揭示了劳动的外在性，即个人以劳动为谋生的手段，并不把劳动活动本身视为自己的目的或本质，因而劳动又外在于个人，这就是外化劳动的含义，体现了人的自然属性。
