2高噪声暴露使女性月经周期的长度缩短，且具有显著性(P.05)，与较短月经周期也有一定的相关关系(OR=1.635，95%可信区间：0.944～2.830)。

The harm extent of Dendrolimus tabulaeformis and D. spectabilis were analyzed by fourteen forest factors, from which four significant ones were selected: crown density, altitude, average diameter at breast height and MLP. MLP is a new parameter suggested in this paper. It is better than diversity index to the harm extent, and it can indicate some information on not only the under story plant species diversity but the forest environment. Using the four key factors a multiphase linear regression model was made for risk analysis of the harm extent of pine caterpillar.

该文首次提出了林下植物喜湿度参数MLP(Moisture-Loving Parameter)，并用包括MLP在内的14个林分因子与松毛虫危害程度进行逐步回归分析，从中筛选出主林层郁闭度、海拔高度、油松平均胸径和林下植物喜湿度参数4个关键因子，与松毛虫危害程度之间均呈显著的负相关关系，并进一步用这4个因子与松毛虫危害程度建立多元线性回归模型，该模型可对松毛虫危害程度进行风险评估。

The paper determines compaction degree of subgrade making use of pumped sand, cutting ring ,nuclear density instrument and drop hammer frequent mensuration methods.

采用灌砂法、环刀法、核子密度仪法、落锤频谱式快速测定仪法4种方法对检测路基压实度的测试结果进行了比较分析；并以灌砂法作为现场测定压实度的标准方法，将其他方法与灌砂法进行回归标定，得出了相关关系，进一步证实了采用灌砂法作为路基压实度检测的标准方法是值得推广的。

采用分形理论对火星南半球中纬度9个陨击坑壁内不同方位发育的冲沟沟头形态进行了研究，结果表明沟头的分维值与冲沟发育程度呈显著的正相关关系。

In this paper, the fractal theory was used to study the gully's alcoves in different orientations of nine craters at the mid-latitudes in the southern hemisphere of Mars. The results suggest significant positive correlation between the fractal characteristics of the gullies and the maturity of their development.

It is revealed that the asymmetric vortices over slender body are formed the breakaways of higher position vortex and generation of new vortex, which are alternately developed on the both sides along the body axis. The correlation between asymmetric vortices structure and distribution of sectional sideforce coefficient has been obtained. A physical model of asymmetric multi-vortices flow structure is developed according to zonal flow analysis.

在此基础上揭示了非对称涡系是通过细长体两侧背涡沿轴向交替脱落、新生而形成的，给出了非对称涡系沿轴向演化、发展的流动结构和截面侧向力分布特性之间的相关关系，在分区分析的基础上提出了非对称涡系结构的物理模型。
