查询词典 ridge

The core of this paper is to analyze and probe into ridge regression from different ideas, such as the existence of ridge parameter K, the choiceness of ridge estimation K , the choice of ridge parameter K and the methods of regression coefficients.

本文简单介绍了主成分回归，阐述了主成分估计方法的原理和优缺点；重点是从不同的角度不同的思想出发，对最常见的岭回归估计法进行了深入的探讨：岭参数K 的存在性，岭估计的优良性，岭参数K 的选择方法等。

Under the plastic-mulched ridge and furrow cultivation, the average soil water content of furrow (12.7%) was significantly higher than that of ridge (9.1%) at the soil depths of 20-100 cm. The locally compacted ridge served as a water flow barrier and a rainfall collection area under locally compacted ridge and furrow cultivation, and the water content of furrow was significantly higher than that of ridge in the same soil depths, which was similar to the characteristic of soil water distribution under plastic-mulched ridge and furrow cultivation. No significant differences were found in soil water content of furrow between locally compacted ridge and furrow cultivation and plastic-mulched ridge and furrow cultivation, with the same efficiency of water collection.

相对于自然垄沟，膜垄的集雨效果明显，沟中土壤平均含水量显著高于垄中，20～100cm土层范围内平均土壤含水量分别为12.7％和9.1％；成垄压实土壤水分在剖面分布状况与盖膜垄沟的水分分布相似，水分向沟内集中，沟中土壤水分含量显著高于同一土层深度处垄中土壤含水量，且与盖膜垄沟处理下沟中土壤水分含量无显著差异，在集水和聚水方面表现出和膜垄的相似性。
