Because the CMYK color business card printing and making basic membership card is based on the dot to overprint colouration and instead use spot color is basic to business card printing and membership card production, although typically spot color is only partial use of the image, but valuation, it is conventional to general printing inks price to estimate; in addition, if the same suites have four business card printing and membership card making color, cards and membership cards for the purpose of making is tantamount to another color, if the business card printing and membership card making machines have no spare business card printing and membership card production unit (for example, less than four color business card printing and membership card making machine or four-colour business card printing and membership card making machine), you have to spend double the amount of real time business card printing and membership card production cost is higher.

因为CMYK四色制卡和会员卡制息根基因此网不背叠印呈色，而搁置专色则根基以实不天制卡和会员卡制息，尽管凡是专色只是在图像的部分搁置，但估价时，不惯上却因此凡是印墨的两倍代价来估算的；此外，如果同版背还来有了四个制卡和会员卡制息色，差制卡和会员卡制息而言不离即是众了一个颜色，如果制卡和会员卡制息机操纵众余的制卡和会员卡制息单位（如超出四色的制卡和会员卡制息机或四色制卡和会员卡制息机），不离又给众花一倍的工夫来制卡和会员卡制息，不败本也不离更高了。

this paper makes the gas remote monitor network as background to do some research on the qos guarantee of the network.qos is a synthesis guide line which can be used to estimate the degree to satisfy with some server,which is a technology to solve the problem of delay and congestion in network.it must integrate multi-qos mechanism to get good qos guarantee in the practical application.three qos models in the ip net application and homologized affective factors are demonstrated.meanwhile,the field of qos protection strategy arrangement in shaanxi coal mine gas network has been picked up as the example.for this situation,the comparison to the different qos models is doing strictly.by combining the tcp congestion control arithmetic with ip congestion control arithmetic,the paper also emphatically describes the corresponded arithmetic model for that.stimulatingly,it is promoted the qos characteristic over-area effectively,which it is based on the original single congestion control.

摘 要：以陕西煤矿瓦斯监测远程联网为背景，研究其联网网络的qos保障策略实现。由于现有的各种qos实现机制无法单独为陕西煤矿瓦斯监测联网网络的qos提供保障，因此在实际应用中必须结合多种机制才能得到较好的qos保障效果。比较了传统ip网络的qos结构体系，通过分析intserv和diffserv两种模型的基本原理、工作方式，并指出其各自的优缺点和网络应用环境，设计了将rsvp协议与diffserv模型相结合来满足瓦斯监测数据传输实时性的要求；针对陕西煤矿瓦斯联网的特性，提出了将tcp拥塞控制算法与ip层拥塞控制算法相结合的算法模型，并且该模型的应用可以在原有单一拥塞控制的基础上有效地提升跨地区网络的qos特性。

The results showed that it was unsatisfactory for the whole samples to estimate the LAI, with the correlation coefficient being only 0.523. After the total samples were divided into four vegetation types, i.e., meadow vegetation, marsh vegetation, shrub and islanded forest, the correlation coefficients and the estimation accuracy were improved evidently. Cubic equations were found to be the best in the different forms of the regression models for retrieving the LAI of wetland vegetation by using CBERS data, with the R^2 value being 0.723, 0.588, 0.837, and 0.720, respectively.

结果表明，整个研究区样本总体的LAI估算效果不太理想，其NDVI与LAI的相关性仅为0.523；将研究区分为草甸、沼泽、灌丛和岛状林4种湿地植被类型，NDVI与各植被型LAI的相关性和估算效果均有很大程度的提高，所建立的LAI遥感反演模型以三次曲线回归方程拟合精度最高，R^2分别达到0.723、0.588、0.837、0.720。

This thesis collects 21 refurnishing work samples, using SPSS program and by means of regression analysis to estimate the generation coefficient for refurnishing waste, it's 0.139t/m2 or 0.231m3/m2 (assume the density of waste is 0.6t/m3), based on the building area. We can also use the coefficient mentioned above to calculate the theory quantity for refurnishing works.

To detect QTL for the body fat-related carcass traits in beef cattle, the single strand conformation polymorphism assay was used for investigating the K232A substitution in DGAT1. Animals from 4 beef cattle populations (32 Luxi, 28 Jinnan, 32 Qinchuan and 26 Limousin × Luxi cattle) were used to estimate allele frequencies and gene substitution effects on several beef carcass traits.
