After feature dimension reduction by Linear Dircriminant Analysis to formulate compact feature vector,...

通过实验选取恰当的分类器参数后，在容量为 177，6 0 0字符(30 0样本/字符类)的测试集上的识别率达到 99.79%，证明了该方法的有效性

We can use a random sample of size n from the population,{(xi1, xi2…, xik; yi): i=1,…,n}, where i denotes observation, and j= 1,…,k denotes the jth regressor.

我们可以使用总体的一个容量为n的随机样本，{(xi1， xi2…， xik； yi)： i=1，…，n}，其中i 代表第i个观察值，j=1，…，k代表第j个回归元。

Then the corrected average hearing threshold of 0.5 kHz, 1 kHz, 2 kHz, 4 kHz and the average hearing threshold of 1 kHz,2 kHz,4 kHz were compared for analyzing the impact of their differences on hearing grades.

为了达成一致，我们在实际操作中对0.5k Hz听阈值进行了修正，对0.5kHz听阈值在计算平均听阈值时的影响进行了分析，结果报告如下。1对象和方法1.1样本和对象以2001年《贵州省年鉴》人口统计数据为基准，按容量比例概率抽样法

Total weight of dissolved mineral constituents in water per unit volume or weight of water in the sample.

在一单位容量或重量的水样本中，溶解于水中的矿物质成份的总重量。

Gastric washing, sputum induction using nebulized hypertonic saline, and bronchoscopy with bronchoalveolar lavage have all been used to obtain specimens for diagnosis, but to our knowledge, the timing and volume of induced sputum have not been well studied, and these 3 methods have not been compared.

洗胃，使用高张生理盐水雾化诱导咳痰，以及用支气管肺泡灌洗进行的支气管镜检查均被运用于诊断获得的样本，但据我们所认识到，诱导咳痰的时机和容量还未被研究，并且这3种方法尚未比较。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
