数据长度 meaning in English
dl data length
Examples
- A new feature in db2 udb v8 allows you to alter the size of a column when required , so you no longer need to create varying length records when you are unsure of future data length growth
Db2 udb v8中的一种新特性允许在需要的时候修改（ alter ）某一列的宽度，这样一来，即使您不能确定将来数据长度的增长情况，也不再需要创建可变长度的记录。 - On the one hand , based on structure risk minimization least squares support vector machine algorithm can gain best results with existing information . the condition of infinite stylebooks is unnecessary . so the outcome is good based on this algorithm when the stylebooks are few
仿真研究了最小二乘支持向量机分类器在不同观测数据长度时、采用不同核函数和不同分类方法时的性能,得出最小二乘支持向量机分类器对不同的模型具有一定不敏感性的结论。 - The efficiency of the controller can be 36 . 36 % or 72 . 73 % when data length is 1 or 2 . when the data length is 4 or above , the efficiency can be 100 % . the effect that on - chip cache has on memory bandwidth is analyzed , and an on - chip cache scheme that can reduce 50 % reference data read
通过多体交错式存取,本文设计的ddrsdram控制器在存取数据长度为1或2个字时,带宽利用率分别为36 . 36 %和72 . 73 % ,存取数据长度为4个字时,带宽利用率可达到100 % ,满足了高清实时解码的要求。 - The simulation on synthetic data is made and the result is discussed . 4 ) the dynamic time warping ( dtw ) theory is applied to actual industrial data to measure the trend similarity of various length time series , which caused by different sample time or chemical reaction time etc . the dtw distance of trend switch series is proposed to filter candidate series and improve the efficiency of similarity searching
在模拟数据上进行仿真实验，并对结果进行分析和讨论； 4 )将dynamictimewarping理论运用到实际工业过程数据处理中，解决由于反应时间、采样时间的不一致以及在间歇过程中，类似变化过程的采样数据长度互不相等而无法实现相似性趋势序列搜索问题。 - One is to use fourier transformation to convert the source signal from time domain to frequency domain and to discard high frequency harmonious components upwards of 19 ( gb / t14953 - 93 d5 . 3 demanding ) , then to have static huffman coding to the quantized char array which is composed of reserved direct current component and basic wave and each high frequency " s amplitudes and angles . the other is to use discrete wavelet transformation to convert the source signal from time domain to frequency domain and to set the high frequency coefficients that its absolute value is smaller than the given threshold to zero , then to have dynamic huffman coding to the quantized char array which is composed of multiple , wavelet ' s level , datum length , low frequency coefficients and reserved high frequency coefficients . mass simulinks and analyses under the two circumstances have done to show that data compression ratio is small and the relative error is also small and within the permission of engineering and the compression problem can be solved in theory of measured datum of power system
第一种情况的压缩方法为：采用传统的傅立叶变换把原始信号从时间域变换到频率域，舍弃20次及其以上的高次谐波成分(保证了gb / t14953 ? 93d5 . 3要求) ，然后对保留的直流分量、基波和各次谐波的幅值和相角数据量化后和量化时分别乘以的倍数系数构成一个数组，以字符形式保存，采用静态huffman编码对变换数据进行压缩；采用离散小波变换把原始信号从时间域变换到频率域，然后对分解得到的高频系数进行阈值量化处理，对乘以的倍数系数、小波变换的阶数、小波变换后的低频、各级高频以及原始数据长度、量化后的低频系数以及保留的高频系数大小、位置构成一个数组，以字符形式保存，采用动态huffman编码对这个文件进行压缩。
