The subjective nature of the utility concept 15 , however , susceptible to ordinal ranking measure . 12 In ordinal preference patterns , one only has to be able to rank alternatives 一from highest to lowest , best to worst , or most satisfying to least satisfying ; no attempt 15 made to quantify the amount by which one alternative 15 better than others - Despite the fact that utility 15 not subiect to precise quantification , it 15 still analytically useful to assume that utility can be represented by cardinal numbers .

公共概念15 的主观本质，然而，易受影响序数等第措施。12 在序数特选样式，你必须只能排列选择一从最高对最低，最好对最坏，或令人满意对最少满意；企图15 没有做定量一个选择15 更好的数额比其他人-竟管公共事业15 不是subiect 写量化，它的大意15 寂静分析有用假设，公共事业可能由序数代表。

The paper gives a brief introduction on theory and means of orebed digitaled and interrelated mining software in domestic and international. On the basis of systematic analysis and research on Jiayashan ore segment, with the mathematic-economic model software bag developed by our library, via the special software Surpac and Micrmine, on the need of the Lanping Pb-Zn mine, the mathematic-economic model of the deposit has been established in Lanping pb-zn mine Jiayashan ore segment. Correlative important technological and economic guide lines have been analyzed and studied. At last, some fruits have been achieved:(1) For the first time, the mathematic-economic model of Lanpingpb-zn mine has been established , digitated and visualed of all kinds of useful information on ore body have been realized.

本文在对矿床数字化的理论与方法及相关的国内外矿业软件综述基础上，通过对该矿床的架崖山矿段地质特征进行充分分析和研究，运用自行研制的大型"矿床数学-经济模型软件包"，以国外矿业软件Surpac和Micrmine为辅助，结合兰坪铅锌矿矿山的实际需求，建立了兰坪铅锌矿架崖山矿段矿床数学经济模型，并对相关的重要技术经济指标进行了分析与研究，最终取得了如下成果：(1)首次在兰坪铅锌矿架崖山矿段建立了矿床数学-经济模型，实现了矿体各有用信息的数字化和可视化。

The law is a sort of hocus-pocus science that smiles in your face while it picks your pocket; and the glorious uncertainty of it is of most use to the professors than the justice of it.

法律是一门哄骗科学，当它掏你腰包的时候，它对你微笑；它最大的不确定之处在于对法律教授，而不是对正义最有用。

Through study on ultra high grade and regularity of minerogenetic enrichment of Hetai Gold Deposits,the influence of ultra high grade on the problem such as negative variation of the grade which exists all over gold mines is pointed out .

通过对河台金矿床特高品位及成矿富集规律的研究，提出了特高品位对黄金矿山普遍存在的品位负变等问题的影响，同时发现有用组份富集地段可单独圈出富矿囊，这对提高入选矿石品位及矿山经济效益有重要作用。

This paper explores shareholder approach, material approach and investment approach to cash flow, and it is concluded as follows: Net present value calculated is equal for shareholder approach and material approach, but for fixed assets investment projects, shareholder approach is far more concise and workable than material approach and provides direct cash flow information with clear and useful economic significance. Investment approach analyzes forecast cash flow for investment projects from a different angle, not only offering additional managerial accounting information, but also testing the properness of and providing theoretical support for shareholder approach and material approach.

通过对股东现金流量法、实体现金流量法和全投资现金流量法模型的研讨，提出如下观点：股东现金流量法与实体现金流量法计算的净现值是相等的，但对寿命期有限的固定资产投资项目，股东现金流量法远比实体现金流量法简洁易懂，便于操作，其提供的现金流量信息直观，经济意义明晰，有用性强；全投资现金流量法从另一个角度进行投资项目的预期现金流量分析，不但能提供补充的管理用会计信息，而且能对股东现金流量法模型的正确性进行验证，互相提供理论上的支持。

The conditions with periodic solution are discussed in detail relating to fractional linear recursive relation of first order and some useful conclusions are obtained.

对一阶分式线性递归关系具有周期解的条件进行了详细讨论，得到若干有用的结论；对二、三阶分式线性递归关系，分别列举了一个具有周期解的例子，并对解的周期性进行了验证。

Pass to proceed the covariance to the unqualified article in quantity in product in factory rate first, analysis, find out to design the useful data to this, apply the in common use method that quantity manage completely, then adoption arrange the diagram proceeds the covariance to the unqualified article, making sure to cause unqualified and main reason in product, apply cause and effect analysis the diagram method finds out the main factor that affect the quantity, then make use of the scatter diagram, keeping the square diagram, controling the diagram to the main influence the factor proceed the analysis, evaluation, certain improvement counterplan, find out the best project, then proceed the technique economic evaluation.

首先通过对工厂产品质量不合格品率进行统计、分析，找到对本设计有用的资料，应用全面质量管理的常用方法，即采用排列图对不合格品进行统计，确定导致产品不合格的主要原因，应用因果分析图法找出影响质量的主要因素，然后利用散布图、直方图、控制图对主要影响因素进行分析、评价，确定改进对策，找出最佳方案，然后进行技术经济评价。
