不匹配

This dissertation systematically studies all 4 possible cases of their combination. Based on geometric invariant, matrix theory, computational geometry, genetic algorithm and so on, a series of effective algorithms are proposed.

本文对上述两种分类的组合共四种情形下的点模式匹配问题，进行了系统的研究；并基于几何不变量、矩阵理论、计算几何、遗传算法等提出了一系列行之有效的算法。

In order to overcome the handicap to extract line-segments from natural hand-printed Chinese characters, the extension is made to other structural features, and the generalized connected background region is defined, and its extraction and recognition algorithm are developed. This recognition algorithm is based on matrix singular decomposition and invariant transformation theory.

针对从自然手写体汉字中难以提取到笔段特征的难题，对汉字的其它结构类特征进行了扩充，提出了汉字的广义背景连通域的概念，并给出了提取广义背景连通域特征的算法以及基于矩阵奇异值分解与不变性变换的广义背景连通域特征的匹配算法。

Power only two generations since the end of Jim Crow.

他的两场胜利，这甚至连比尔克林顿都匹配不上。

To my knowledge a player's latency is not a factor in the matchmaking process.

就我所知，玩家的延迟状况不会影响匹配系统。

If the sequences are the same size and the corresponding elements match, then neither is lexicographically less than the other.

如果序列长短相同且对应元素匹配，则在字典序上两者都不小于另一个。

If no matching catch is found, then the program calls the library terminate function.

如果找不到匹配的 catch，程序就调用库函数 terminate。

But this kind of invasion cannot avoid the detection of IDS using the protocol analysis technology.(2) In the invasion activities of hackers using TCP, the actions about scanning and Denial of Service utilizing the three-handshake protocol are general. The characteristics of the actions are dynamic for its lie on a series of packets from beginning to end. So the IDS using the traditional pattern match technology cannot detect these actions effectively, but the IDS using the protocol analysis technology can do its.

2在利用TCP协议进行的黑客活动中，比较常用的是利用三次握手过程进行扫描行为和拒绝服务攻击，这类攻击的特征必须根据前后的一系列数据包才能确定，因此攻击特征具有动态性，很不适合于采用模式匹配作为信息检测技术的IDS，但协议分析技术可较为迅速地检测出这类攻击。

The fractional Fourier transform is a linear operator,and will not be influenced by cross terms.

分数傅立叶变换是线性变换，不存在交叉项，采用分数傅立叶变换搜索匹配动目标信号，使其能量汇聚。

However, the toughest problem which cumber application of time-grating at the beginning of practicality is not technique barrier but no matchable numeric controlling devices or upper equipments.

但是在产品推广初期，延缓其推广使用的不是技术问题，而是缺少相匹配的上位机或数控装置。

The iron, in which the carbide has a high chemical stability and the matrix possess a matchable oxidation resistance, can be well resistant to abrasive wear at elevated temperature. In addition, the high temperature abrasive wear resistance of the high Cr—Ni cast iron containing eutectic carbide is much better than that of 0Cr26Ni14 heat resistant steel in which no carbide exists.

结果表明，M〓C〓型碳化物的高温化学稳定性对高Cr—Ni铸铁合金的抗高温磨料磨损性能有显著的影响，碳化物的高温化学稳定性愈好，基体的抗氧化性又能与之相匹配，合金的高温抗磨性就愈好；而且，含有碳化物的高Cr—Ni铸铁合金的高温抗磨性远优于不含碳化物的0Cr26Ni14耐热钢。
