分量

Unsupervised algorithms such as principal component analysis 、 vector quantization、 independent component analysis and factor analysis can be understood as factorizing a data matrix subject to different constraints.

典型的非监督学习算法，如主分量分析、矢量量化、独立分量分析、因子分析等，均可以理解为对原始数据矩阵在一定条件限制下进行分解。

The transformation of the instantaneous value symmetry component applied,the positive sequence space vector of fault component of the voltage and current can be derived.

应用瞬时值对称分量变换，可提取电压、电流故障分量的正序空间向量。

Some key technologies on the system have been introduced: the vector calculation module as a signal processing module used to adjust the phase of the feedback signals, the feedback kicker cavity and the notch filter used to filter the DC component and revolution frequencies component in a signal and save the feedback power.

其中重点介绍了在该系统研制过程中所涉及的部分关键技术：矢量运算模块的开发使得反馈系统的调试简易方便；Notch滤波器用于滤除反馈信号中的直流分量以及回旋频率分量，节省反馈功率；激励条带的研制。

The aircraft acceleration affects the response significantly, especially the vertical component of aircraft acceleration.

过大的垂直加速度分量或过小的水平加速度分量都可能使原稳定的系统变得不稳定。

During the storms, to the magnetic field vertical component of magnetic declination and there has been a marked ups and downs, but most features of the horizontal component of H.

在磁暴期间，地磁场的磁偏角和垂直分量都有明显起伏，但最具特征的是水平分量H。

In the example shown, the two currents are 90 out of phase, so the vertical component of the magnetic field is sinusoidal, while the horizontal is cosusoidal, as shown.

因而，如例子所示，磁场的垂直分量是正弦形式的，而水平分量是余弦形式的。

It can also be decomposed into the zero- input component and the zero-state component.

它也可以分解成零输入分量和零状态分量。

Besides, the detection of a number of target navigation parameters can be estimated. The goal of this paper is to present a PCA electric field algorithm for calculating the target headings, size/velocity rate and port/starboard location in relation to the electric sensor axis. This PCA algorithm is based on the simultaneous analysis of the three components （longitudinal, athwartship and vertical） of the electric signature in order to compare the time evolution of their waveforms as a way to determine the target parameters.

此外，还可估算探测大量的目标航行参数：目的是提供一种主分量分析电场算法，以计算相对电场传感器轴线的目标航向、尺寸／速率、左右舷位置：此种PCA算法基于同时分析电场特性的3个分量，以便比较这些波形随时间的变化，作为确定目标参数的方法。

The spectrum peaks nearby 530nm and 480 nm are corresponding with BTSD and BMD respectively. It is found from measurement that the luminescence peak from BMD is bluely shifted. The atoms of BTSD nearby dislocation core are affected by tensile stress along the Burger's vector direction leading to its band gap narrowed. In addition, there is the effect of part quantity of edge dislocation in BMD existed. Part of atoms in BMD are strained by compressive stress leading to its band gap narrowed, in other words, the wavelength from BMD is shorter than that from BTSD.

从测试结果中还发现BMD 的发光位较BTSD有所蓝移，分析认为BTSD位错芯附近原子沿伯格斯矢量方向只受到拉应力，致使禁带宽度变窄，BMD由于除了具有螺型位错的分量外还具有部分刃型位错的分量，而刃型位错中有部分原子受到压应力的作用，导致禁带宽度增宽，从而使得BMD的发光波长比BTSD短

Two different ways of sample tilt were used in CD messurements to prove that the linear dichroism and birefringance had no effect on CD signal of cholesteric helices of the liquid crystal.

分别用两种方法旋转玻片进行CD测试，结果证明线性二向色性分量和双折射分量对胆甾层片螺旋的CD信号强度没有大的影响。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
