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.

The ground states properties of Ne-isotopes were calculated with Relativistic mean field theory. Compared with the experimental datas, its discovered that the nucleus properties chang regularly with the changes of neutron number when the proton number is even. The results proved indirectly that even nucleus has no direct influenced on another kind of nucleus. Besides, the applicability of Relativistic mean field theory in this region was tested.

用相对论平均场理论计算了Ne同位素的基态性质，并和实验比较，发现当质子是偶数时，核的性质有规律地随中子数的变化而变化，由此间接证明了偶数核子对另一类核子无直接影响；同时，也检验了相对论平均场理论在该区域的适用性。

It is presented that indirect assimilation experiment of CMW data from TCFM method improves effectively not only on vertical velocity field but for precipitation.4 Based on theory analysis, E-Ir relationship is brought forward with two electrification mechanisms. One is inductive mechanism, i.e., cloud particles collide with precipitation particles then flick away, the other is noninductive mechanism because of different temperature, i.e., bigger supercooled cloud particles collide and freeze with hail particles combined with ice scraps. By means of CINRAD and FY2C data assimilation, precipitation intensity Ir can be obtained, then electric field intensity E, discharge time and locations can be achieved with supposed threshold 300KV/m. Though it can not distinguish between IC (Intra-Cloud) lightning and CG (Cloud-to-Ground) lightning, results are still comparable to LLS observations.5 Example analysis shows that the relationship between precipitation data from AMS and CG data from LLS is not very clear.

The area of Nantong in Jiangsu Province is a fluvial plain by Yangtze River. To the north of the mouth of river to the sea is a beach plain, which was once the boundless ocean in history, through the development of history, form the wide seabeach finally. The two plains, which are in the different location, have the different ways to utilize the soil. The Yangtze Fluvial Plain, whose soil is fertile, grew to be the well-known area of producing cotton, with people outnumbering the farmland, while the beach plain became a famous salt field. With the development of the coastline, Huainan saltern declined day by day and at the beginning of 20th century, under the advocate of local government and the call of modern industrialist, Mr. Zhang Jian, the salt field in the North of Jiangsu province underwent a great reclaim-plain movement, which brought a tide of spontaneous immigration to the area. During the movement, the key problem is the contest for the ground. As the ownership of the land of salt fields is complex, the unification of the ownerhship of land was not easy. Zhang creatively took advantage of the form of modern joint-stock company to solve the problem.

江苏省长江口北岸现南通地区为长江冲积平原，沿江口向北为海岸淤涨地区，历史上这里曾是汪洋大海，经过多年历史演变，终于形成广阔的海滩，两个不同的淤涨地区，对土地的利用截然不同，沿江地区土地肥沃，逐渐成为著名的棉产地，人多地少；沿海则成为我国历史上著名的两淮盐产地，随着海岸线的演变，淮南盐场日益没落，20世纪初，在政府的提倡和近代实业家张謇的发动号召下，苏北盐垦地区发起了一场波澜壮阔的垦殖运动，与此相适应的则是一场自发的移民大潮，在这两大潮流中，最核心的是对地权的争夺，由于两淮盐场地权复杂，统一地权实属不易，张謇等人创造性地运用近代股份公司的形式解决了这一难题。

On the ground that the covariance between the disturbing gravity field elements is not isotropic, the covariance matrix has a complicated structure (its submatrix being not repetitive Toeplitz matrix) and thus its degree cannot be degraded with transformation matrix method, so it cannot be put into practice. So far, the application of least squares collocation to the modeling and data processing of the horizontal disturbing gravity field observations has not been found in literature.

由于水平扰动场元之间的协方差并非各向同性，导致协方差矩阵结构复杂(子矩阵不是 Toeplitz 循环阵)，不能利用变换矩阵将其降阶，无法付诸实践，迄今尚无最小二乘配置理论应用于水平扰动场元观测量的模型化公式和数据处理方法。

Ajax son of Oileus never for a moment left the side of Ajax son of Telamon, but as two swart oxen both strain their utmost at the plough which they are drawing in a fallow field, and the sweat steams upwards from about the roots of their horns- nothing but the yoke divides them as they break up the ground till they reach the end of the field- even so did the two Ajaxes stand shoulder to shoulder by one another.

迅捷的埃阿斯，俄伊琉斯之子，现时一步不离忒拉蒙之子埃阿斯，像两头酒褐色的健牛，齐心合力，拉着制合坚固的犁具，翻着一片休耕的土地，两对牛角的底部淌流着涔涔的汗水，中间仅隔着油滑的轭架挡出的那么一点距离，费力地行走，直至犁尖翻到农田的尽头――就像这样，他俩挺立在战场上，肩并肩地战斗。
