假设检验

To test the four hypothesis,a positive study is conducted using the 93 private listed companies which are all listed before 2002 on China's A share market. Both the descriptive statistic analysis and regression test were carried out from two angles: direct control and indirect control.

为了对假设进行验证，我们整理选取了2001年年底之前在国内上市的93家纯A股民营上市公司为样本，以2002年至2004年为数据窗口，从直接控制和间接控制两个角度对其股权结构和经营绩效之间的关系进行了描述性统计和回归检验。

The paper also attempts to develop a frame reflecting the relationship between two kinds of preference. Furthermore, the paper attempts to reveal the laws of preference change, and explain the phenomenon of preference revers...

本文尝试给出了内层稳定偏好与外层偏好变化的关系思考框架，进一步探讨个体偏好变化的原因，并对偏好逆转现象进行解释，强调学习过程对于个体在复杂场景中建立新的偏好关系的作用，同时，本文也尝试通过经验数据检验部分假设。

In §5.3,we discuss the hypothesis test problem of the scale parameter change point.

否则，接受原假设〓，认为不存在变点。上述两种检验，我们都给出了模拟结果。

Hence, in this paper, we particularly investigate serial correlation test in these models, and obtain some useful results.

因此，本文在方差齐性的假设下，详细研究了这些模型的序列相关检验问题，得出了一些有益的结果。

In this study we tested thehypothesis that the spinal block from a CSE technique resultsin a more extensive spread of local anesthetic in the subarachnoidspace than the single-shot spinal technique.

在这项研究中，我们检验了关于 CSE 技术中的脊麻阻滞会导致局麻药在蛛网膜下腔的扩散范围比单次脊麻方法广的假设。

With this normal approximation, standard processes for statistical inferences such as hypothesis testing and confidence interval are developed for testing whether the process is capable and providing an interval estimate on CpkT, respectively.

我们也以理论证明的方式找出估计量的常态近似分配，透过常态近似分配，统计假设检定、信赖区间、信赖下限都可以用来检验制程是否是有达到特定的标准。

In order to test this hypothesis, based on previous works by Uziel(1993), Martohardjono(1991), Flynn(1987), and White(1988), I conducted a study which exam in ed the acquisition of Subjacency by ma in land Ch in ese speakers learn in g English as a second language.

为了检验此假设，在Uziel(1993)，Martobardiono(1991)，White(1988)，Flynn(1987)等研究的基础上，我在中国大陆英语学习者身上进行了实验研究，调查邻接原则的习得。

After descriptive statistic, we used reliability analysis, confirmatory factory analysis, correlation analysis, regression analysis and structural equation model to test the hypothesis of this research.

在对数据进行描述性分析之后，本文主要采用信度分析、效度分析、多元线性回归分析以及结构方程建模等方法对研究假设进行检验。

If their new data do not support their hypotheses,scientists come up with other testable explanations.

如果新的资料不支持他们的假设，科学家想出其他检验的解释。

While we obviously have much to learn, we are beginning to develop logical explanations and testable hypotheses about these methods, and this is the hallmark of good science.

虽然我们显然有很多值得学习，我们已经开始制定合理的解释，有关这些方法可检验的假设，这是良好的科学的标志。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
