The results showed that with the increasing of human-induced disturbance intensity, the amounts of small soil particle (silt and clay) and large aggregate decreased, and the amounts of soil micro-aggregate and natural soil particle increased; soil porosity decreased in the surficial soil,especially, in which the large porosity significantly decreased;.
结果表明 ,随人为干扰强度的增加 ,土壤中细土 (粉粒、粘粒 )和大团聚体数量减少 ,小团聚体和原生土壤颗粒增加 ;土壤表层孔隙度减小 ,尤其是大孔隙明显减少 ;土壤有效水降低 ,持水供水能力减弱 ,渗透系数减小 。
We want to know the quantitative relation of the disturbance intensity and the forest structure.
结果表明,人为干扰能在一定程度上增加香格里拉亚高山森林树种多样性,但随着人为干扰强度的增加,其树种多样性又逐渐降低,群落出现断层,森林资源量减少,进而发生逆行演替,危害了森林生态系统的良性循环。
A prediction model for dry strength of ceramic sanitaryware shaped by gelcasting based on improved BP artificial neural net was developed by using the Levenberg-Marquardt training algorithm.
采用Levenberg-Marquardt算法对BP神经网络进行改进,对获得的实验数据进行训练,首次建立了卫生陶瓷凝胶注模成型工艺中单体、引发剂、交联剂、催化剂含量和坯体干燥强度的映射网络模型,从而可利用该模型来预测在一定的有机成型添加剂含量下卫生陶瓷的干燥强度。
The result showed that intensity of heat island and dry island maximized at 20:00 in summer and autumn with 6℃ heat island intensity as the highest, and 2℃ average, as well as with 30% dry island intensity as the highest, and 9% average.
选择了具有代表性的 4 个点，在春、夏、秋、冬分 8:00、14:00、20:00 三个时段进行了气温观测，得到热岛强度和干岛强度以晚上 20:00 最大，四季中以夏秋季节最大，获得最大热岛强度为 6℃，四季平均约为 2℃，最大的干岛强度为 30%，四季平均约为 9%。

The drought experience of soil and crop could be described perfectly by combining drought intensity(I) with drought degree(D).
干旱强度和干旱程度结合才能完整地描述土壤作物干旱状况,土壤干旱强度I是土壤剖面失水速率的函数,干旱影响逐渐累积并增强就构成干旱程度D,据此提出了包含I和D二个指数的土层干旱指标表达模式。
