As feature extraction acts an important role in pattern recognition system, we propose three novel feature extraction methods for HCCR: a、Two structural feature extraction methods, Stroke Cross Counting Features and Peripheral Features are studied. According to the characteristics of Chinese handwriting samples, we extend the SCCF and PF respectively to weighted elastic SCCF and weighted elastic PF. Experiments show that the modified feature extraction approaches are better than original approaches. b、A new statistical feature extraction method——Elastic Meshing Directional Decomposition Feature extraction is proposed. According to the stroke statistical properties of Chinese character, we first decompose a handwritten character pattern into four directional subpatterns. Then a set of elastic meshes are applied to each of the four subpatterns respectively to extract the pixel distribution features.

统计识别方法：利用统计模式识别的经典方法——Bayes分类方法来进行汉字识别的研究，特征提取是统计模式识别的关键，本文着重围绕手写体汉字的特征分析和提取方法进行了研究，提出了三种特征提取的新方法： a、两种改进的结构特征提取方法：在笔划密度特征和外围特征的基础上，结合手写体汉字的特点，提出了加权非均匀笔划密度特征、加权非均匀外围特征的特征提取新方案； b、一种新的统计特征提取方法——弹性网格方向分解特征，根据汉字方块字的特点及笔划分布的统计特征，对手写体汉字进行横竖撇捺四方向的分解，并利用一系列的弹性网格对汉字分解后各分量的象素进行统计而提取特征，实验证明该特征提取方法用来进行手写体汉字识别是十分可行和有效的。

But in fact, vitamin A effects on vision has nothing to do with myopia, which mainly affects the eyes in the dark light, vision (so-called "dark adaptation"), vitamin A deficiency can lead to a reduced ability to dark-adapted (the worst case, can cause night blindness), but also will lead to eye conjunctiva (commonly known as "white eye" part) or the cornea (commonly known as "black eye" part) of the damage, but does not cause myopia.

但实际上，维生素A对视力的影响与近视无关，它主要影响眼睛在暗光下的视力，维生素A缺乏会导致暗适应能力下降，还会导致眼睛结膜或角膜的损害，但不会引起近视。

Ace of spades-Motorhead If you like to gamble I tell you I'm your man You win some, lose some, it's all the same to me The pleasure is to play it makes no difference what you say In a shaky lead the only card I need Is the ace of spades Ace of spades Playing like a high roller dancing with the devil Knowing it could blow, it's all a game to me 7 or 11 snake eyes watching you Double up or quit devils take a split Ace of spades Ace of spades You know I'm going to lose And gambling is for fools But that's the way I like it baby I don't want to live forever And don't forget the joker Pushing up the ante I know you got to see me Read them and weep the dead man's hand again I see it in your eyes take one look and die The only thing you see you know it's gonna be The ace of spades The ace of spades

A force out is made when a baserunner is forced to leave his base when the batter becomes a baserunner himself, and a fielder successfully tags the next base before the runner can reach it.

a force-out 开始指在体育的垒球运动中&封杀出局&：即是击球员成为跑垒员时，造成击跑员或前位跑垒员丧失跑垒的权利，而刺杀出局者。

Results Postoperative shallow anterior chamber took place in 2 eyes in Group A and 9 eyes in Group B. Postoperativ IOP were 12.8 mmHg and 13.6 mmHg at 2 weeks in Group A and Group B respectively, and 17.6 mmHg and 20.8 mmHg at 6 months. Postoperative functional filtering blebs were 36 eyes in Group A and 27 eyes in Group B.

结果 A组发生浅前房2眼，B组发生9眼。A组和B组平均眼压术后2周为12.7 mmHg和13.6 mmHg，术后6月为17.6 mmHg和20.8 mmHg；两组术后功能性滤泡分别为36眼和27眼；且A组术后并发症发生率明显低于B组。

For the Cranberries, assembling a best-of covering the first decade of their career means compiling their singles in chronological order, which turns out to be a foolproof approach for a band that can be uneven over the course of a full-length album but has always managed to express itself well on the two-to-four catchiest cuts.

Sequenza VIII , written in 1976 for violinist Carlo Chiarappa, is both a homage to the instrument's technical potential, its content deriving essentially from the notes A and B, and also, in that its form. is akin to a chaconne (variations over a repeated melodic or rhythmic idea in the bass), to the composer whose Sonatas and Partitas laid the foundation for all subsequent violin music, Johann Sebastian Bach.

模进 VIII 》作于1976年，是一首小提琴独奏作品，为小提琴家卡洛·齐亚拉巴而作，同时也是对乐器技巧潜能的挑战，它的内容其实来自 A 和 B 两音，结构与巴赫为后世小提琴作品奠定了基础的奏鸣曲与组曲中的恰空相仿。

We employ a computer to simulate the characteristics of objects and circumstance, and calculate radar video echo date, then through computer inter-face circuit and the relative circuit and D/A conveners, the echoes are outputted to a radar signal processor. The video signal simulator can be use to debug a terminal homing radar system instead of the former part of radar.

该模拟器通过计算机模拟目标和环境特性，产生雷达视频回波信号数据文件，然后通过微机接口电路、回放电路和D／A变换输出该视频信号，接至雷达信号处理机；它可以代替雷达前端对末制导系统进行调试；实验结果验证了该模拟器的有效性。
