查询词典 stroke

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。

When left when the test-drive after repair in shop main engine is adding this ship to 540r/min, supercharger occurrence asthma brace up phenomenon, rotate speed lifts slightly again, noise shakes very big, smoke evacuation temperature is normal, hair of on the high side of temperature of air inlet duct is very hot, as good as of smoke evacuation smoke constant, supercharger rotor rotate speed and the rotate speed of right leader supercharger that work normally comparative. 2 breakdown analyse this model diesel engine supercharger breathes heavily brace up the reason has the following sides. Bearing of 1 supercharger rotor damages, bring about on the low side of supercharger rotor rotate speed or wave motion, make inadequacy of compressor part air feed and diesel engine and its demand do not match, bring about air current not to stabilize generation to breathe heavily brace up. 2 diesel engine offers oil, match gas to time forbid, match gas, draw well time and disorder, bring about supercharger to breathe heavily brace up. 3 supercharger nozzle jams, cause smoke evacuation not free, circumfluence of exhaust stroke waste gas, enter jackknife of new energy of life with the below one stroke that take energy of life, produce air current to hit generation to breathe heavily brace up. Canal of 4 smoke evacuation jams, smoke evacuation not free, bring about waste gas circumfluence, hit generation of new energy of life to breathe heavily brace up. 5 jams into gas mouth, enter gas inadequacy, generation breathes heavily brace up. 3 trouble removal are based on above analysis, adopt the following measure to remove trouble.

该舰在厂修后试车时左主机在加至540r/min时，增压器出现喘振现象，转速再略升高，声响震动很大，排烟温度正常，进气管温度偏高发烫，排烟烟色无异常，增压器转子转速和正常工作的右主机增压器转速相当。2故障分析该型柴油机增压器喘振的原因有以下几个方面。1增压器转子轴承损坏，导致增压器转子转速偏低或波动，使得压气机部分供气不足和柴油机及其需求不匹配，导致气流不稳定产生喘振。2柴油机供油、配气定时不准，配气、发火定时紊乱，导致增压器喘振。3增压器喷嘴堵塞，导致排烟不畅，排气冲程废气回流，和下一进气冲程进新气重叠，发生气流冲撞产生喘振。4排烟管堵塞，排烟不畅，导致废气回流，冲撞新气产生喘振。5进气口堵塞，进气不足，产生喘振。3故障排除基于以上分析，采取以下办法排除故障。

When Dr. Mark Alberts, director of Duke University Medical Center's Stroke Acute Care Unit, urges doctors in smaller communities to take stroke treatment seriously, they often say,"I can't leave my busy practice to rush down to the hospital, read a CAT scan and decide whether a patient needs t-PA."

杜克大学医学中心的中风紧急治疗组的负责人马克·艾伯茨医生督促小型社区的医生们认真对待中风治疗时，他们常常会说：&我不能放下手中正忙着的事情匆忙跑到医院，读造影扫描报告，决定病人是否需要t-PA治疗。&
