两对称

In the first approach the metadata extraction is viewed as a classification problem. Three statistic classification models, including Support Vector Machines, Perceptron with Uneven Margins, and Maximum Entropy are studied. The approach suffers from the problems of ignoring the variance in lengths of documents and ignoring the dependency of text units within documents. To solve the problems, our second approach takes the metadata extraction as a sequence data labeling problem and makes full use of the sequential information.

论文首先研究了基于分类的元数据抽取方法，考察了支持向量机、非对称间隔感知机和最大熵模型在ADME中的应用；然后针对分类方法中存在的忽略文档之间的差异、不考虑文档上下文等问题，提出了基于序列数据标注模型的抽取方法，并结合最大熵马尔可夫模型、投票感知机模型和条件随机场模型进行了研究；最后本文根据前两种方法的设计思想和优缺点，研究提出一种新的结构预测模型—— CDASP（Coordinate Descent Algorithm for Structure Prediction），并将其应用于元数据的自动抽取中。

"Inorganic compound Any substance in which two or more chemical elements other than carbon are combined, nearly always in definite proportions, as well as some compounds containing carbon but lacking carbon-carbon bonds (e.g., carbonates, cyanides)."

无机化合物：由两个或更多的碳以外的化学元素组成的化合物，几乎总是对称的，某些化合物含碳但缺少碳－碳化学键。

I write in fairly legible cursive, so my concern was that the two lowercase s 's would be asymmetrical, not have the same roundness with a little point cresting the top, the way I was taught.

我用草体书写，所以我担心的是那里面的两个小写s不对称，而且我以前学习写s上面都有个圆点。

Methods: We have respectively done correlation analysis including auto-correlation and cross correlation analysis for 10 derivation electrodes＇ and 21 derivation electrodes＇ EEG data, and acquired each derivation＇s result of auto-correlation analysis and symmetrical left with right derivation＇s result of cross-correlation analysis at different condition and event.

分别对10导联电极和21导联电极的两组脑电图数据做互相关和自相关的相关性分析，得出在不同条件、事件下脑的各导联电极的自相关分析结果和左右对称导联电极的互相关分析结果，最后得出相关性值随实验条件和事件的具体变化。

In terms of the difference between encryption key and decryption key,it can divide into symmetry cryptogram and public key cryptogram.

根据加密密钥和解密密钥在性质上的差异，可以将密码体制分为对称密码和公钥密码两大类。

Aconnector is an injection molding from the positioning kits and installed in the positioning of the Inner-Block, packaged in the seat of the spring and reed composition, described the position set of cylindrical Chengyuan, the location of the hole sets A circular from the convex to capacity at the first spring home district and the Department of card system for the second district of the blocks in the positioning of the sets of holes in the first referred to the Ministry, since the port inside the shaft Two symmetrical to the hole within the targeted slot, a connector and adapter combination of positioning, positioning slot in the rear, the agreement sets in the central part of setting the level of L-shaped slots, so that the connector and adapter reliable combination of the Practical use of new high-strength engineering materials first injection molding, greatly simplified the process, a connector improve the accuracy of the positioning trough of the utility model to improve, even if the products improve the safety and reliability, and more convenient assembly, product structure is simple And optimize the manufacturing process, reducing costs and improve productivity.

一种连接器是由注塑一次成型的定位套和安装在定位套内的机座、套装在机座上的弹簧和簧片组成，所述的定位套呈圆柱状，该定位套的内孔由一内凸圆隔出容置弹簧的第一区部和卡制机座的第二区部，在定位套的内孔，位于所述的第一区部处，自端口向内，轴向对称设置两条内孔定位槽，起到连接器与适配器结合的定位作用，在该定位槽尾部，约定位套的中部设置L形水平槽孔，使连接器与适配器可靠结合；本实用新型采用高强度工程材料一次注塑成型，大大简化了加工过程，提高了一种连接器的精确度，本实用新型定位槽的改进，即使产品安全可靠性提高，又更方便组装，产品结构简单、制造工艺优化，从而降低了成本，提高了生产率。

Contribution of asymmetric cytosine deamination was found to be weak to TAP in most phyla, and strong to RAP in all the Proteobacteria but weak in most of the Firmicutes. This possibly reflects the differences in their chromosomal replication machineries.

不对称的cytosine deamination作用对大多数的门中的TAP贡献很小，对Proteobacteria的RAP贡献显著，而对大多数Firmicutes的RAP贡献很小，这可能反映了这两门物种间染色体复制机制的不同。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
