不溶性直链淀粉的含量与普鲁兰酶活力成负相关；不溶性直链淀粉的含量与直链淀粉和支链淀粉的比值成正相关，其中四个样品为显著水平，一个样品接近显著水平。

The logarithm transformed concentrations of HCHs had significant correlation with angular transformed soil TOC contents, while this correlation was not found for the case of DDTs.

HCHs的对数浓度与角变换的土壤TOC含量存在较为显著的相关关系；而对于DDTs关系并不明显。

The Von Mises angular function is used to describe the angular correlation for the distributed source and derive a novel distributed source model from the quantitative angular correlation.

利用阵列接收信号协方差阵的特征值分析了源内角度相关程度对有效信号子空间的影响。

对于实际应用和理论推导中，源内角度何等相关程度的分布源相关模型可等价于分布源独立或相干模型要做具体分析，不能笼统地认为所有分布源相关模型都用分布源独立模型描述和处理。

There exists a close relation between growth characteristics and wood properties of the provenance. The height and breast height diameter growth of the provenance had a positive correlation with tracheid diameter and annual ring width, and a negative correlation with tracheid wall thickness and wood density.

种源生长与材质性状间存在一定的相关关系，如种源的高径生长与管胞直径和年轮宽之间存在正相关，而与管胞壁厚和木材密度之间却存在一定程度的负相关。

The periodic correlation function and aperiodic correlation function are discussed in this thesis.

本文讨论了序列的周期相关函数和非周期相关函数，归纳总结了部分周期相关函数的概念及性质，与此相对应给出了部分非周期相关函数的概念。

The partial periodic correlation functions are summarized, and the notion partial aperiodic correlation function is brought forward correspondingly.

这两个概念在研究序列的随机性时常被忽略且很模糊，但它们却对序列的局部随机性有很重要的影响。

Among all OMRP treatments, biggest change range appears in IMRP12 followed by IMRP10 and IMRP13.There was positive correlation between change range and increasing rate of available phosphorus. There was positive correlation between increasing rate of available phosphorus and decreasing amplitude of XRD argentite's main peak value.

这一结果与6种磷矿粉的活化效果，即磷矿粉活化前后有效磷的增加值相一致，说明活化剂通过降低磷矿粉X-衍射主峰的峰值改变了磷矿粉的结构，由此提高了磷矿粉的化学有效性。

We performed a field experiment by the end of 2004, and based on the data of this experiment, we studied the amplitude degression and corresponding seismic attenuation factor of both single event waveform and cross-correlation function. It is found that, same as single event waveform, cross-correlation function could be used to assess the seismic attenuation.

依据野外现场实验的数据，我们分别以单次和多次激发为源，讨论了事件波形和互相关函数波形的振幅变化及相应的介质品质因子，结果发现，与事件波形一样，互相关函数波形也可以用于计算介质的衰减系数。

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