圆盘

A disk having a fixed or variable opening used to restrict the amount of light traversing a lens or optical system.

"具有固定或可变孔的圆盘，用来限制穿过透镜或光学系统的光量。"

A set of complex Morlet wavelet are applied on projection slice of each direction to decompose each projection into several frequency channels,the average and variance extracted are computed in each frequency channel,and then linear regression model is employed to computer realationship feature between frequency channels.1-D DFT is applied to features and the amplitudes of Fourier coefficient are selected as features,then the extracted features are rotation invariant.

该算法是将一定大小的图像进行二维傅里叶变换；其次在变换后的图像中央选择一个圆盘区域，并在方向［0°，180°］内进行等间隔角度频率抽样，实现方向分解，使用一组复Morlet小波对每个方向上的映射切片进行小波变换，从而实现多通道频率分解；在各个频率通道中计算均值和方差作为特征，并利用线性回归模型计算频率通道之间的关系特征；将特征沿方向进行一维傅里叶变换并取其幅值，从而得到旋转不变性特征。

We give some equivalent characterizations of Bloch type functions in term of fractional derivative, via studying the relative of growth of the different order fractional derivatives of holomorphic function, including the form of supremum and limit, the form of integral and Carleson measure, which are the generalizations of some known results in the unit disc and in the unit ball.

我们从研究全纯函数分数次导数的增长性入手，利用分数次导数给出了它的一类刻画，包括上确界和极限形式的特征，积分形式的特征以及Carleson测度形式的特征，推广了单位圆盘和单位球上一些已有的结论。

The sun looks like a shiny gold plate,but it is really a big ball.

太阳看似一个闪光的金色圆盘，但实际上却是一个巨大的圆球。

A novel photocatalytic reactor, which can use sun light and graniform photocatalyst, was developed and evaluated. Hydraulics studies show that the actual mean residence time was approximately 1. 5 to 2 times greater than the theoretical mean residence time, which is of great advantage for degrading the pollutants in the reactor, and that the high reaction rate can be obtained by increasing the rotational speed.

设计了一种新型提升式圆盘多相光催化反应器(exalting round-platephotocatalytic reactor，ERPPR)，该反应器的主要特点是能够利用太阳光和粒状催化剂，通过对ERPPR水力学特性的研究发现，该反应器的实际平均水力停留时间约为理论平均停留时间的1.5到2倍，反应器内循环流量与提升桨转速成正比。
