This technique uses a spiral phase plate with a small central aperture placed on the Fourier plane of so imaging system. If the spiral phase filter is rotated by a certain angle around its central axis, a phase shift between the zero-order spatial frequency component and the remaining of the object is produced, and the magnitude of this phase shift is proportional to the rotation angle. Using this property, we can record a sequence of intensity distribution of the output beams corresponding to different rotation angles, and then digitally reconstruct the objects by using a phase-shifting algorithm. Both the theoretical analysis and simulation experiment results demonstrate the feasibility of this approach.

Firstly, according to this character, primacy central point is detected by the exploring extremum method in the windows of 3×3 pixels. Then, basing on this central point, approximate normal line at ±45°、0°and 90°angle are drew.if the minimums of normal line is at central point and the difference between the minimums and the maximum in the normal line is more than the threshold, this point is considered to the edge point of image.

首先，在3×3象素的窗口中，如果中心值为最小值，则以该点为基础，以±45°、0°和90°方向作为近似法线带，然后判断该法线上的象素最小值是否在切点上（即是否在法线的中心点上），再通过检验切点与轮廓法线上亮度极大值的差值是否超过阈值，来判断切点是否为边缘轮廓上的点。

In the central island of Honshu; rich soil, such as Hill-based Fuji volcanic belt (from the central island of Honshu by the Pacific Ocean to the Izu Oshima Island seven); to birds, such as seamounts mainly of sea birds volcanic belt (in the Honshu Island in the Sea of Japan side of the north-east); Zunqian to mountain-based Nasu volcanic belt (from the western island of Hokkaido, Honshu Island, as central to north-east); to Tokachi Yue, Huangshan, and other sulfur-based Kuril volcanic belt ( From the central island of Hokkaido to the north-east extended to the Kuril Islands).

In the process of realizing the remote control of electromotor meter, it probes into the realization of the GPRS wireless collector emphatically which is on the kernel ground. It adopts the means of area-centralizing control to manage the electromotor meters affiliated by it. It communicates with the central control station by GPRS Modem and transmits the commands and data to the instrument by wireless, which makes the collection and transmission of the field data come true. In the process of realizing the remote control of voltage transformer meter, according to the actual requirement, it adopted the chips and modules that are different from the front means to design and realize the GPRS wireless communicating controller corresponding with the devices. It also introduces the mixed—mode Communication integrating the GSM with GPRS to settle the problem that too many GPRS terminals connecting with the central control station synchronously will affect the performance of the central control station.As a whole system, the central control station is the kernel of the digital oil field.

在油田电机表远程控制方案实现中，着重介绍了处于核心地位的GPRS无线集中器的实现，它采用区域集中控制的方式管理下属的石油电机表，与主控站采用GPRS Modem进行通信，与仪表则采用无线电方式进行命令和数掘的传输，实现了现场数据采集传输；在配电变压器表远程控制方案实现中，根据应用需要，采用与前一个方案完全不同的硬件芯片和模块，设计实现了与仪表设备——对应的GPRS无线通信控制器，并针对同时挂接在主控站上的GPRS终端太多会对主控站性能产生一定的影响这个问题，引入了GSM和GPRS相结合的混合通信模式。

Third should be noted that, with the Shanghai Urban Construction, and the whole process to expand rapidly, we find that Central has been a lot of plot and central urban area to enjoy the same market treatment, that is, said that if in accordance with the Inner Ring to determine likely this situation will disappear, to separate the role of Central Link in strengthening the future, may be opened in the Link, but Link with many special sections, and the Inner Ring of them the ordinary price of the lot may be will be separated, so that we can explain the Central Link which is now the emergence of a large number of more than 9000 pieces, nearly 10,000 of the sale price, there is a product itself, a good product is always in support of our prices.

第三方应当指出的是，与上海城市建设，整个过程迅速扩大，我们发现，中央一直是很多情节和中部城市地区享有同样的市场待遇，那就是，他说，如果按照内环，以确定这种情况可能会消失，分开的作用的中心环节加强未来，可能是打开了该链接，但链接有许多特殊的部分，以及内环线，其中普通价格该地段可将分离，以使我们能够解释的中心环节，而现在出现了大量的超过9000件，将近一万个的销售价格，有一个产品，一个好产品永远是支持我们的价格。

Methods Central point at the central clival depression was marked with the help of CT and stereotactic apparatus in 20 formalin-fixed cadaveric heads. The bone resection was divided into four steps via FLA:① drilling of the jugular tuberculum;② partial mastoidectomy;③ removal of the occipital condyle;④resection of the lateral mass of C1 with mobilization of the vertebral artery. After each step of the bone resection was completed, the exposed area of the central clival depression and the area of exposure 15 cm above the central point were calculated.
