Based on the fact that the stable tautomer of NTBC by calculation is different from that from X-ray experiment, the quantitative structure-activity relationship (Comparative Molecular Field Analysis, CoMFA and Comparative Molecular Similarity Index, CoMSIA) were studied on the five possible active tautomers in order to conjecture the structure of NTBC binding with HPPD.

In this organogel structure, the p–p stacking interactions among the HPB moieties, the hydrogen-bonding interactions between the urea moieties, and the van der Waals forces between the long alkyl chains cooperatively stabilized the aggregate structure; these are well-known interactions in gel systems.2a,5 Specifically to clarify the effect of the hydroxyl group in the HPB unit on gelation, we also designed and synthesized reference compound 2, which does not contain an adjacent hydroxyl group and thereby cannot induce its planar keto tautomer upon excitation.

在这个organogel结构、p-p叠加之间的相互作用在HPB根、实验之间的相互作用尿素根之间，范德华力长链烷基之间的合作稳定了合计结构；这些都是著名的交互作用的凝胶 systems.2a明确厘清，羟基的效果集团在HPB装置设计和凝胶，我们也是合成的化合物、参考不包含了邻近的羟基从而无法归纳其平面在keto tautomer激励。

The theoretical foundation of electrical prospecting is that the resistivity of different rocks and minerals are different, and different fields have different responses to telluric current structure. So we can inverse telluric current structure of medium according to the response, that is, the resistivity and distribution of underground rock and mineral.

电法勘探的理论基础是不同岩石矿物的电阻率不同，不同地电结构的场响应不同，因此我们可以由观测的场响应反演出介质的地电结构，即地下岩石矿物的电阻率及分布。

LDefinition, structure and feature. With a new definition and a static and dynamic analysis of its structure, this paper argues for such features as universality, complexity, variety and temporariness.

The function of enclosure was to enable the dispersed fields of a landowner in a single parish to be concentrated without increasing and decreasing in the proportion before and after enclosure; Enclosure was the precondition of the estate structure in the late 19th century, while the main motivation and approach of that was social mentality and estate market; In the estate structure of late 19th century, agent was the main actor to manage the large and middle estates; Landowner, tenant farmer and agricultural labour affected and restricted each other, which was full of tender feelings.

圈地运动的作用只是使土地所有者在单个教区内分散的土地几乎数量不变地集中到一起；小土地所有者不仅没有消失，而且在1780-1832年间圈地进行最为剧烈的时期出现了数量增加的状况；圈地运动为大地产的形成创造了前提，十八、十九世纪土地流动的主要动因和途径则是大众的心态和市场的激励；在19世纪晚期地产结构中，大、中地产的管理主要是通过代理人体系进行有效的运营；地主、农场主、农业工人三者之间相互影响、相互制约，充斥着温情。

In this framework, image frame, audio and text are represented, which are the three modalities in video shots as data points by the 3rd-order tensor. Then a subspace embedding and dimension reduction method is proposed, which explicitly considers the manifold structure of the tensor space from temporal-sequenced associated co-occurring multimodal media data in video. It is called TensorShot approach. Transductive learning uses a large amount of unlabeled data together with the labeled data to build better classifiers. A transductive support tensor machines algorithm is proposed to train effective classifier. This algorithm preserves the intrinsic structure of the submanifold where tensorshots are sampled, and is also able to map out-of-sample data points directly. Moreover, the utilization of unlabeled data improves classification ability.

在此框架中，视频镜头首先被表示成由视频中所包含的文本、视觉和听觉等多模态数据构成的三阶张量；其次，基于此三阶张量表达及视频的时序关联共生特性设计了一种子空间嵌入降维方法，称为张量镜头；由于直推式学习从已知样本出发能对特定的未知样本进行学习和识别，最后在这个框架中提出了一种基于张量镜头的直推式支持张量机算法，它不仅保持了张量镜头所在的流形空间的本征结构，而且能够将训练集合外数据直接映射到流形子空间，同时充分利用未标记样本改善分类器的学习性能。
