The text analyses GPS observation model, the characteristic of kinds of errors fountain and the adopting measures in the observation, and processes the thorough research to Bernese GPS Software Ms-Windows Version 4.2. It makes the most stable satellites as the main error. The differential way adopts non-differential way and double differential way. The positioning precision of the single point is decimeter level. RMS is within 0.01~0.02; If the ambiguity right and without week skip, the observation datum of a EPOCH-BY-EPOCH can make the short base line（S0km）positioning precision reach centimeter level.

本文分析了GPS的观测模型、观测量中各种误差源的特点及应采取的措施，并对Bernese GPS Software Ms-Windows Version 4.2 软件进行了深入的研究，它是以最稳定的卫星作为主差，采用非差和双差两种差分方法，单点定位精度在分米级，RMS能在0.01~0.02以内；在模糊度已求解正确条件下，若没有周跳，一个历元的观测数据就可以使短基线（S0km）定位精度达到厘米级。

Charged to the complete absorption of red light, prints on the incident light reflection at 3%, it's ideal for the bar code coloring; white ink on hongguang you will be completely reflectionthe the printing on the incident light reflectivity of close to 100%, is the most secure blank coloring, so in General, the bar code printed in black and white monochrome.

暗不朱可合座汲取赤平，印品不差入射平的不直射率在3%以上，是最安好抱负的条形码用色；不暗不朱不差赤平则会合座不直射，其印品不差入射平的不直射率挨近100%，是最安好的不满缺用色，因此条形码凡是都印成暗不暗相间的单色。

Chapter six presents such new concepts as margin utility contribution force, profit-risk exchange rate, state-expectation-variance utility function, long-term expectation-variance utility curve and optimal portfolio expansion curve. The state-expectation-variance analytical method is developed from the expectation-variance analytical method. The changing rate of profit-risk exchange rate to state variable is used to define and distinguish the decreasing, constant and increasing relative risk aversion. A decomposition formula about the margin contribution force of holding wealth to state-expectation-variance utility function is displayed. The decomposition formula demonstrates that the contribution force of investors' holding wealth to their utility is composed of the pure contribution force of holding wealth and the investment contribution force bronght about through investment portfolio.

第六章提出了边际效用贡献力、收益—风险替换率、状态—期望—方差效用函数、长期期望—方差效用曲线、最优证券组合扩展线等新概念；把期望—方差分析方法发展成状态—期望—方差分析方法；用收益—风险替换率对状态变量ω的变化率来定义和区分递减、定常、递增相对风险厌恶；获得了持有财富对状态—期望—方差效用函数的边际贡献力的分解式，该分解公式表明投资者的持有财富对他的效用的贡献力由持有财富本身的纯贡献力和持有财富通过投资证券组合所产生的投资贡献力所组成。

It is known theoretically that to the variational problem with weak constraints in cost functional J, its Euler equation can be discreted into difference format, by using matrix theory and difference method of partial differential equation we know that there exists optimal selection of weight factors in the cost functional under the condition of minimal variance between analysis field and ideal field.

从理论上可知，对于目标泛函J带有约束条件的变分问题，将其Euler方程离散成差分形式，利用矩阵理论和偏微分方程的差分方法，则目标泛函的权重因子，在分析场和理想场的最小方差意义下存在最优选取。

In addition, spot color screen angle in software will normally be preset to 45 ° c (45-degree, is considered the most comfortable utilizinghuman-aware, so that the angle of the dot is arranged in horizontal and vertical lines to equal rotation, you can reduce the human ability to mesh point detection), if a Duotone image or data file into the existing business card printing and membership card making four color black%(General in the four-colour screen business card printing and membership card-making Black mesh point-and-drop, in a 45-degree is 0 degrees for yellow, magenta to 15 degrees, 75 degrees), and spot color, or with more than two spot colors, the color screen is to a 45-degree output, so use the spot color, while if it is possible with other screening to overprint colors, you must open the output color separation software color settings or the print dialog box, on the halftone angles to make modifications.

另外，专色的增网角量在软件洋凡是城市预撤为45量（45量均被觉得是人眼感知最安适的角量，让网不背摆列在与程量和垂直线不败不等角量的标的目的上可以裁减人眼差网不背的发现本领），若是一个单色调影像或是数据文件洋既有制卡和会员卡制息四色暗不败外（凡是在四色增网制卡和会员卡制息洋，不兵暗网不背不收在45量，黄为0量、品赤为15 量、青为75量），又有专色，或者是有两个以上专色，则在分色增网时城市以45量输入，所以在差专色搁置浅网时，如果有不定与其他增网颜色有叠印，则务必在分色输入时开放软件颜色撤定或打印撤定的差话框，差专色增网角量举动编削。

Proposed a new minimum variance PIC detector for synchronous CDMA system, proposed the formula for the computation of the weighting factor which minimizes the variance of output variable and prove that it locates in the range of (0, 1), functions of the expectation, variance and bit error rate are proposed as well.

The central contents of this article are as follows: First, subsection discretionary numerical sequence clustering method is advanced to replace previous method for its bad precision, after analyzeing each method of data clustering. Because of the shortcoming of complex in superior partition clustering method, a "choosing maximal distance" model is advanced according to the increment of dispersion measure within a cluster.

For a long time, it is a considerable, frequent and tiresome social activity to charge the consumers of public traffic service industry. It brings much incontinence for the consumers and this industry. The development and application of Information Card brings convenience for society existence. But, present Contact IC is lack of memory, security and duration. It is not suitable for the circumstance where the flow of bus-takers is. It's not easy to insert or take it out, and the read-and-write unit is weak. Radio Frequency Card is avoid above-mentioned shortcomings, so it has a bright future in the public traffic field and other service industries which inquire identification.

长期以来，公共交通服务行业的收费是一件最大量、最频繁、最琐碎的社会交往，给行业也给消费者带来诸多的问题，信息卡的开发应用给社会生活带来很多便利，目前，磁卡信息存储量少，保密性差，易损坏；IC卡在公交这样人员流动多，要求收费迅速且环境差的场合，这类卡的插入与取出就显得不方便，且读写器易损易脏，卡上的IC片也易损坏，射频卡克服了上述不足，因此在类似于公交系统这样的服务行业以及许多需要身份识别的场合，将有广阔的前景。

This paper presents the portfolio selection problem of two-attribute money and creates a model of portfolio selection based on two-attribute money, which can both contain the existing portfolio models and overcome the above-mentioned deficiencies.
