There is a positive relationship between the degree of knowledge tacitness and transfer cost; there is a negative relationship between the degree of knowledge overlap and transfer cost; there is a positive relationship between the degree of physics distance and transfer cost, but the relationship is not that significant; there is a positive relationship between the hierachical distance and transfer cost; there is a negative relationship between the trust and transfer cost.

结论如下：首先，从知识情境来说，知识隐含性与知识转移成本成正相关关系；其次，在相关情境重，部门差距与知识转移成本的正相关关系这一假设未能通过验证，知识重叠性与知识转移成本成负相关关系；知识转移双方物理距离与知识转移成本成正相关关系，但显著性处于临界状态，不能完全支持假设；职位距离与知识转移成本成正相关关系；在接收者情境中，基于能力的信任和基于善心的信任与知识转移成本成负相关关系。

And I confess that if all that I knew of Reverend Wright were the snippets of those sermons that have run in an endless loop on the television and You Tube, or if Trinity United Church of Christ conformed to the caricatures being peddled by some commentators, there is no doubt that I would react in much the same way.

坦率地说，假设我对赖特牧师的了解完全来自电视和You Tube反复播放的那些布道录像，或者假设"三一联合基督教会"(Trinity United Church of Christ)的实际情况完全符合某些评论员喋喋不休的讽刺性描述，毫无疑问我也会有差不多类似的反应。

The reason is that every methods ,based on second-order statistics, impose many preconditions for signals and geological models, like supposing pratical signals are Gauss ones, noise is Gauss white noise, and telluric system is linear non-minimum phase one. But practical situations are not like this.

其原因是基于二阶统计量的各种方法，对信号和地质模型作了许多假设和要求，如假设信号为高斯信号，噪声为高斯白噪声，大地系统为线性非最小相位系统，但实际情况并非如此。

Hypothesis test of clock synchronization is discussed in this paper.

在时钟偏差的统计分布特性近似于服务正态分布的假设条件之下，提出了基于非中心t分布的时钟同步假设检验方案。

In the entire mathematical statistic, hypothesis test is a very importants and valuable part, but it exists the risk of committing two kinds of errors.

在整个数理统计中，假设检验是一个很重要很有应用价值的部分，但假设检验中存在着犯两类错误的风险。

The paper focuses on the tetraploidy black locust on Loess plaeatu of West Shanxi province, applys steady state promoter method and image processing technology to study the days transpiration water consumption in different weather ,different seasons and different site conditions,has primary analysis on the impact of environment on the transpiration and carries on the calculation to the tetraploidy locust tree by the single leaf water consumption to the single tree water consumption in CaiJiachuan watershed; Uses fast weighing method to measure and analyze the transpiration water consumption of five different herbs under the tetraploidy black locust forest (Capillary Wormwood,Vanilla,Agropyron Sristatum , Common Sowthistle and Medicago Sativa) in short time, in the same and different growcrop,and calculates the average transpiration water consumption per square metres ;the soil colome weighing method was used for determining diumal variation quantity of soil moisture evaporation, analyzing the dynamic variation and caculating the total quantity of soil evaporation water consumption from May to August ; then 5 kind of suppositions about the types of surface vegetation coverage are proposed in experimented site and the total evapotranspiration water consumption are calculated under 5 suppoitions ,aim at providing preliminary theoretic basis for ascertaining the transpiration water consumption of tetraploidy black locust forest,controling standing forest density and optimizing the forest grass deploy on loess plaeatu of west Shanxi province .

本文以两种不同立地条件下的四倍体刺槐林为研究对象，采用了气孔计法对蔡家川流域生长季内不同天气状况下(典型晴天、阴天和半阴天)四倍体刺槐日蒸腾耗水规律、不同季节(生长季初期、中期和末期)的蒸腾耗水规律、两种不同立地条件下四倍体刺槐蒸腾耗水比较以及影响四倍体刺槐蒸腾耗水的环境因子进行初步研究分析，并对四倍体刺槐由单叶耗水量向单株耗水量进行推算；采用经典快速连续称重法对四倍体刺槐林地生长的主要5种草本植物(白蒿、香青兰、冰草、苦苣和苜蓿)短时段内蒸腾耗水规律、不同生长季内蒸腾耗水规律、同一生长季不同种类草本植物蒸腾耗水量进行了比较分析，并且采用面积与重量比的方法推算出了单位面积四倍体刺槐林地几种主要草本植物平均蒸腾耗水量：采用土柱称重法测定了5月份～8月份土壤水分蒸发昼夜变化量、对试验期内土壤蒸发量动态变化作了分析、推算出了试验地5月份～8月份土壤蒸发耗水总量；对试验地地表植被覆盖类型提出了5种假设，推算出5种假设的情景下蒸散耗水总量，旨在为晋西黄土区四倍体刺槐林蒸腾耗水量的确定、林分密度调控以及林草优化配置等提供初步的理论依据。

It is the key for engineering process control to settle the process time, but the PERT assumes the process time obeysβdistribution or two point equal probability distribution, and this assumption affects the accuracy of project plan.

工序作业时间的确定是工程进度控制的关键，但PERT假设工序作业时间服从贝塔分布或两点等概率分布，这一假设影响了工程进度计划的准确性。

One method of preserving it is, to use it as sparingly as possible; avoiding occasions of expense by cultivating peace, but remembering also that timely disbursements to prepare for danger frequently prevent much greater disbursements to repel it; avoiding likewise the accumulation of debt, not only by shunning occasions of expense, but by vigorous exertions in time of peace to discharge the debts, which unavoidable wars may have occasioned, not ungenerously throwing upon posterity the burthen, which we ourselves ought to bear.

在你们可能被邀参与的所有变革中，你们应当记住，要确定政府的真正性质，正如确定人类其它体制一样，时间和习惯至少是同样重要的；应当记住，要检验一国现存政体的真正趋势，经验是最可靠的标准，应当记住，仅凭假设和意见便轻易变更，将因假设和意见之无穷变化而招致无穷的变更，还要特别记住，在我们这样辽阔的国度里，要想有效地管理大家的共同利益，一个活力充沛的、并且能充分保障自由的政府是必不可少的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
