In the process of contour tracing, contour lines are gained by tracing in anticlockwise order and a method of backdate search which ensures the correctness of the algorithm is used for contour tracing at those pixels where other contour pixels can not be continuously traced. By analysis of the neighbouring pixels, this paper avoids judging those pixels that no need to be compared again.

提出了一种逆时针追踪轮廓线的彩色图像区域分割算法，其思想是按逆时针顺序追踪轮廓线，在追踪过程中避免了像素点的重复判断，采用回溯搜索解决奇点问题，从而保证了追踪过程的连续性和正确性。

Far over the ice, between the hemlock woods and snow-clad hills, stands the pickerel-fisher, his lines set in some retired cove, like a Finlander, with his arms thrust into the pouches of his dreadnaught; with dull, snowy, fishy thoughts, himself a finless fish, separated a few inches from his race, dumb, erect, and made to be enveloped in clouds and snows, like the pines on shore.

一个渔夫站在冰面上，位于铁杉树林与覆盖了皑皑白雪的小山之间，像芬兰人一样，他将鱼线垂放在小河湾中，手插在大衣口袋里，一动不动，像有着鱼一样的思维，因此他自己就是一个无鳍的鱼，而他的同类在冰面下的不远处；他静谧地伫立着，被云和雪包裹着，就像岸边的松树。

It involves a spherical primary mirror and the secondary mirror with profile given by computer.lt is not necessary for the new optical system to obtain the on-axis solar image,so the secondary mirror may have a simpler profile.

一种由球面主镜和由计算机算出曲面型线的二次镜组成的新型二次反射聚光系统，可以减少制造困难，当这种光学系统用于太阳能聚光器时，由于不需要得到轴上的太阳像，其二次镜型线可更为简单。

Results:Fractures were demonstrated definitely with transaxial imaging,SSD and MPR in all patients.The length,shape,direction and displacement of fractures,the appearance,size and space location of detached bone fragments,and dislocation of joint were displayed stereoscopically by SSD.Joint disruption and detached bone fragments within joint could be best viewed by MPR.

结果：所有病例CT横断面、SSD和MPR像均明确地显示了骨折，SSD像立体地显示了骨折线的长短、形态、走向，碎骨片的形态、大小、空间位置以及骨折的移位和关节对位状况，跨关节MPR像显示关节受累和关节腔内游离碎骨片更佳。

Results: The angle that adjusting the reference line on the transverse plane is 32. 85°±6.76°, on the coronal plane is 14.15°±9.02°. The facial canal appears "ㄟ" on double oblique imaging geniculate ganglion, tympanic segment, post lap segment, mastoid segment were showed clearly. The achievement ratio is 100%. The segment displaying on double oblique imaging is more than transverse plane, coronal plane and sagittal plane.

结果：面神经管双斜位图像需要在横断位参考图像上旋转参考线的角度为32.85°±6.76°，在冠状位参考图像上旋转参考线的角度为14.15°±9.02°；在面神经管双斜位图像上，面神经管表现为&ㄟ&形，由前向后同时显示出膝状神经节、鼓室段、后膝部和乳突段；面神经管双斜位成像成功率为100%，面神经管行程的显示程度大于横断位、冠状位和矢状位。

A loop not is a good choice if you are using two strands of floss (which you do in most cross stitch) or when your design calls for just a few stitches like a flower, star, eye, etc. Fold your threads in half and insert the cut ends in the eye of this needle, leaving a loop at the bottom or tail.

不是一个循环是一个很好的选择，如果您正在使用牙线的两个链，或在您的设计要求只是像花一样，明星，眼睛，等你的线程折一半，并加入一些切缝733297本针眼，留在底部或尾巴一个循环。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
