查询词典 factors

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。

Analysis is made on block effect to cutters of PDC bit with 3 factors: different top shape,cutter-distributing and wearing degree.By the interaction(radial range and altitude difference of each cutter) of three adjacent cutters,the cutter block is further analyzed with these factors,but wearing degree is simplified to be considered as the cutters vertical to the assembling plane.

中文摘要：对PDC钻头冠部形状及不同的布齿密度和切削齿在不同的磨损状态下对PDC钻头切削齿受力的影响进行了分析；用相邻的3个切削齿之间的关系（不同的切削齿与切削齿之间的径向距离和切削齿之间的高度差）来分析PDC钻头冠部形状和切削齿布齿密度对切削齿受力的影响，以及将切削齿的磨损状态简化成与切削齿在钻头上装配方向垂直的平面来分析切削齿磨损状态对切削齿受力的影响。
