效果的衡量

First, it discusses the impact of the number of dimensions on rating results and the four meta-dimensions in AC. Second, it introduces the indexes of rating accuracy in AC and expounds different types of rater training programs and their impact on rating accuracy. Third, although AC has proved good criterion-related validity, the research on its construct validity has not yet reached an agreement.

首先，文章讨论了评分维度的数目对於评分结果的影响，以及评价中心中的4个元维度；其次，介绍了评价中心中衡量评分效果的指标，并讨论了评分者培训的分类及其对评分效果的影响；第三，虽然评价中心具有良好的效标关联效度，但对於其结构效度的研究至今尚无统一结论。

The effects of the ratio of water and the sample, extracting temperature, extracting time, and the sample particle size on water-soluble active ingredients of Ampelopsis grossedentata were investigated with single factor and orthogonal experiments as a measure of total flavones and water extraction ratio.

以水溶性活性成分总黄酮和水浸提率作为衡量浸提效果的评价指标，分别采用单因素和正交实验L9(34)确定了茶水比、浸提温度、浸提时间和样叶粒度对显齿蛇葡萄总黄酮和水浸提率的影响，得出了影响的主次顺序为茶水比、浸提温度、样叶粒度和浸提时间。

Finally, a new method of errors analysis (midpoint and barycentric measure method )are presented to measure the errors of surface reconstruction, strong practicability shows that this error measure method is feasible to testify the validity of surface reconstruction.

最后，本文对重建曲面进行了误差分析，提出了一种新的误差度量方法，即中点、重心误差度量法；此方法运算效率高，并在一定程度上可以衡量曲面重建效果的好坏。因此有很强的实用性。

Efficiency: Measures of efficiency reflect how well such resources as inventory, capacity, and capital are utilized in supply chain operations.

效率/Efficiency：效率可以通过库存、生产能力和资产在供应链运营中的应用效果来衡量。

Based on the evaluation system, the plants whose relative remediation age was between 0~10 years were named as"Hyperaccumulator"and those between 10 ~ 50 years were named as"Accumulator".7 In the experiments six kinds of substrates were mixed with different solid wastes and the absorption and enrichment of plants on heavy metal Cd was studied. The results showed that relative remediation age was an ideal index to evaluate the capability of the phytoremediation on heavy metals, because it took into account more factors which affected the absorption evaluation effects than others, such as the heavy metal content and the biomass of the over-ground part of plants, the heavy metal content and the whole gross in substrates, harvesting frequency of plants and the environment standard of heavy metal. This made relative remediation age be suitable to the sorption capability evaluation of not only different plants on one heavy metal but also one plant on different heavy metals.8 It can be drawn from the relative remediation age of heavy metal Cd that the absorption capability of different plants was not same.

以相对修复年限为评价指标定义相对修复年限为0-10年的植物为"超富集植物"，10-50年的植物为"富集植物"。7在由不同废弃物按一定的比例混合配制的六种土地复垦基质上，系统地研究了几种植物对重金属镉的吸收和富集情况，结果表明，相对修复年限既适用于不同植物对同一种重金属元素的吸收能力的评价，又适用于同一植物对不同重金属元素的吸收能力的评价，是衡量重金属元素植物修复效果的理想指标。8从不同植物对同一基质重金属镉的吸收和富集能力看，不论是经过多年种植的基质，还是第一次种植的基质，小白菜和油菜都是相对理想的植物；而黑麦草、高羊茅和苜蓿的吸收效果并不理想。

It is to think network advertisement at or surpass traditional advertisement, cheap Mo place does not go to charge; 2 it is Shu of one-sided pursuit impression, impressional Shu is one of levels that measure network advertisement effect, but sometimes one Ge visits Ke Zai a website can produce ten Ge even Shu of two Ge impression; San is to feel integrated big website is straighter than hanging down effect of advertisement of site of is good, but accept the product ad with apparent feature of numerous target group to great majority, this kind of choice is unwise.

一是以为网络广告等于或胜过传统广告，费用低廉无所不到；二是片面追求印象数，印象数是衡量网络广告效果的标准之一，但有时一个访客在一家网站就可以产生十几个甚至二十几个印象数；三是以为综合大网站比垂直站点广告效果好，但对于大多数受众目标群体特征明显的产品广告，这种选择是不明智的。

Ecological Potential is an indicator to measure the comprehensive effects of multiecological factors confecting.

生态潜力是衡量多种生态因子综合配合效果的指标。
