Under the circumstance of satisfying the two necessary conditions of late-developing advantages, the potential advantage can be transformed into the motive force of development to propel the society forward and reduce the development gap between the early-developing countries. The process is a closed circle of damped oscillation. It can only turn into increasing oscillation circle with the consistent innovation and breakthrough so that the backward countries can exceed the early-developing countries.

潜在的后发优势在满足后发优势发挥作用的两个必要条件的情况下可转变为发展动力，推动社会向前发展，缩小与先发国家之间的发展差距，这一个过程是一个减幅振荡的闭路循环，只有在引进、消化的基础上不断创新、突破，才能打破单纯由后发优势导致的减幅振荡闭路循环，进入增幅振荡循环，后发国家才有可能超过先发国家。

Liu Hui, a mathematician of the Three Kingdoms period, claimed that "3 to 1" was rather a ratio of the circumference of the inscribed hexagon with the diameter of the circle than a ratio of the circumference of the circle with the diameter.

刘辉说，数学家的三国时期，声称" 3比1 "是相当比例的周长与登记六边形直径的圆圈比比圆周长与直径。

When the moving-star arrived to the side of another star, both two stars(star-A and star-B) began to move in a circle orbit that the two stars are constantly at the two terminals of a diameter of the circle.

当它移到另一颗星星的一侧时，这两颗星星顺势互相环绕，各绕了半周，移过来的那颗绕到了另一侧。

The dynamic mechanism of the optim; control of regional human-earth system is to simulate the optimal distance between "man circle" an "earth circle". The spatial structure of the optimal control includes core area, occurrence area, sustair ing area and function area.

人地系统优化调控的动态机理在于模拟"人圈"与"地圈"的最佳距离，优化调控的空间结构包括核心区、发生区、支持区和作用区，各功能区相互竞争的结果形成区域定位与空间共生。

The method for the point sets selection of point Hough transform and the scan direction for image of searching the point sets were improved by using the geometrical characteristic of the concentric circles:The center of the concentric circles was obtained in the accumulative array firstly,radius was obtained by the mean of distance between the circle center and every edge points afterwards,both the circle center and the edge of the concentric circles were detected accordingly.

利用同心圆的几何特点对点Hough变换边缘点的点组选取方法和搜索点组的图像扫描方向进行了改进：首先由累加阵列确定同心圆的圆心，然后由圆心到各个有效边缘点距离的均值求出半径，从而检测出同心圆的圆心与边缘。

"You may create lots of splashes in your life, but the waves that come from those splashes will disturb the peace of all your fellow creatures," he said. Remember that you are responsible for what you put in your circle and that circle will also touch many other circles.

他说："在生命的水面上，你也许能激起许多波纹，而你所激起的波纹也会打破别人的平静，"要谨记，对你所激起的波纹中所包含的东西负责，因为这些东西会接触、影响到别人的波纹。

"You may create lots of splashes in your life, but the waves that come from those splashes will disturb the peace of all your fellow creatures," he said,"Remember that you are responsible for what you put in your circle and that circle will also touch many other circles."

All this to say that I'm glad filmmaking hasn't become completely ironic. I can enjoy an ironic film as much as the next person, but they usually involve a message of some sort. One that's delivered in a smirkingly clever way that requires little in the way of talent.

所有这些都是说，我很高兴电影制作没有变成完全讽刺艺术，我可以和下一个人一样享受讽刺电影的乐趣，虽然他们经常会被划归到一定级别，技术方面不需要很高的才能。
