变圆

With rotational invariance of circle, image was divided into different sectorial sub blocks in polar coordinates, and the sum of regional pixels was taken as sector eigenvalue. Then a normalized feature space by norming sector feature set was got.

以圆的旋转不变特性为基础，在极坐标下将图像分割为不同的扇形子块，并将各子块区域灰度和作为表示扇形子块的特征，然后对子块特征集进行归一化，所得的归一化扇形特征集作为特征选取的空间。

Effect of partiality degree material physics character change and ununiform of winged slice temperature on transfer heating of circle core pipe rectangle winged slice was examined.

If we do not quickly deal with this serious problem, the matter will continue to get worse, with social consequences far more tragic than mere dollars and cents.

Generally, the best time to observe an outer planet like Jupiter is when the planet is retrograding. That's because then it is roughly opposite the sun in Earth's sky. This causes it to be brighter (think of it as full like the full moon), and be visible longer at night.

一般来说，想观测像木星这样的带外行星，最好就是当它出现向后运行现象的时候，这是因为此时在地球上的我们会看到行星是与太阳相对的，这也导致行星更亮（想象它就像满月那样又圆又亮），而且在夜晚出现的时间也变长。

THE dark, floppy hair has gone, and the face is a little rounder, but otherwise Jerry Brown, at 71, looks much as he did when he slept on a futon on the floor of his office and squired Linda Ronstadt round town.

Please follow the grinding line of ACP when you wash the panels with sponge, cloth or brush broom. If you washing in a circle way, the spots maybe can be removed but it will became ugly because of lost surface luster.

在用布、尼龙做的海绵、刷帚等清洗，控洗时一定要沿着铝塑复合板的磨削纹路，平行控过去；象画圆那样地控洗，虽去污但会破坏表面光泽，使之变难看。
