based on the results of upi, sas and sad, these 557 subjects are divided into two groups : problem group and normal group . through the variance analysis, distinction of values between these two groups, distinction of values between male students and female students, and the effects of gender differences on each of the two groups are examined
根据557名大学生在新生心理测试中upi、sas、sds问卷的结果，将他们区分为心理健康状况的问题人群和正常人群，用方差分析对这三种测试的问题人群和正常人群做了价值观调查问卷的两阶因子的差异检验，同时也对男生和女生的价值观以及他们在问题人群和正常人群中表现出的差异性进行检验。
this text focuses on applying abc thought to make research of and design erp system's cost accounting and controlling flow on design stage 、 purchase stage 、 production stage and sale stage, primarily including that we : ( 1 ) on design stage, imitate and optimize activity-based cost, as well as establishing the relationship between production design and enterprise production activity chain and product bom through erp's cost imitation function, rejecting invalid and non value added activity on applying the thought of abcm, then optimizing activity chain 、 production structure and production design from the cost point of view; ( 2 ) on purchase process, applies the thought of abc to account and control purchasing cost; ( 3 ) on production stage, apply thought of abc to calculate the product cost, and use the method of activity difference variance analysis to control product cost; ( 4 ) on sale stage, apply thought of
本文重点在erp系统的设计、采购、生产和销售等四个阶段，运用作业成本思想对其成本核算及控制流程作相关的设计研究，主要包括，一在设计阶段对作业成本进行模拟和优化，即通过erp成本模拟功能，建立产品设计方案与企业生产作业链和产品bom结构之间的对应关系，应用作业管理的思想，剔除无效非增值作业，优化作业链及产品结构，从成本的角度优化产品设计方案；二在采购过程中，应用作业成本思想核算与控制采购成本；三在生产制造阶段，运用作业成本思想计算产品成本，并采用作业差异分析法控制企业的产品成本；四在销售阶段，运用作业成本思想计算客户服务成本，为erp系统中的客户关系管理提供准确的决策数据信息。
on the loess plateau, water is the main limiting factors for vegetation growth . root distribution characters have special ecological meaning as it reflected the utilizations of trees to the environments . even-aged stands of robinia pseudoacacia on slope lands facing south and north were selected as sampling plots for root distribution investigation . investigatiing results showed that indicated that on all sites, root biomass decreased with depth, and the distribution depth of fine root was deeper than that of coarser root . the results of variance analysis indicated that there were great differences in root biomass among different diameter classes, and coarser root was the main sources of variance, and the root biomass, especially fine root ( < 3mm ) biomass on northern exposition sites was bigger than that on southern exposition sites . analysis of the vertical root distribution parameters, root extinction coefficient, indicated that the value of on northern exposition was more than 0.982, while the value of on southern exposition was less than 0.982, which indicated that the vertical root distribution depth of robinia pseudoacacia on southern exposition was deeper than that on southern exposition . and the distribution depth of fine roots ( < 1mm ) was deeper than that of thicker roots ( < 3mm ), which was in favor of the uptake of water and nutrients from deeper layers, helped the trees to adapt the arid environment, and promoted the growth of the upper parts of the tree
在中国西北黄土高原地区,水分是树木生长发育的主要限制因子.根系分布特征由于反映了树木对环境条件的利用程度而具有更加特殊的生态意义.本研究选择阳坡和阴坡不同立地上年龄一致的刺槐林调查了根系分布特征.根系垂直分布特征的调查结果表明,在所有立地上,根系生物量随着深度的增加而降低,其中细根的分布深度大于粗根的分布深度.方差分析结果表明:不同立地上不同径级根系的分布特征也有明显的差别,粗根是差异存在的主要原因,阴坡立地上的根系生物量,特别是细根生物量大于阳坡立地上的.对根系消弱系数的分析结果表明,阴坡立地上的根系消弱系数大于0.982,而阳坡立地上的根系消弱系数小于0.982,说明阴坡立地上刺槐根系的生物量在深层土壤中的分布相对量更大一些.其中细根的根系消弱系数大于粗根的,这种根系分布特征有利于根系对深层土壤水分养分的吸收利用,进而促进树木地上部分的生长发育.图3表3参15
we make comparative analysis of technical efficiency, pure technical efficiency and scale efficiency while choosing the year1997and 2000 as the model samples . and we also study the degree of the efficiency departure between banks through variance analysis while comparison of the efficiency is made between state-owned commercial banks and the newly founded banks chronologically
