The effects of individual and combined additions of urea (100 μg N g-1 soil) and insecticide (triazophos at field rate, FR) under different moisture levels of air-dried soil (AD), 50% of water-holding
Analysis of phospholipid fatty acids (PLFAs) was used to estimate the microbial community structures of eight Chinese red soils with different fertility levels and land use histories. The total amount
A mutual information based 3D non-rigid registration approach was proposed for the registration of deformable CT/MR body abdomen images. The Parzen Windows Density Estimation (PWDE) method is adopted
A 21-d incubation experiment was conducted under controlled laboratory conditions to study the effects of elevated temperatures (10, 25, and 40 ℃) on some microbiological and biochemical properties in
Sorption of acetanilide herbicides, metolachlor, acetochlor, pretilachlor and butachlor on eight soils with various physical and chemical properties was studied. The adsorption isotherms could fit Fr
介绍了 CPPCSS仿真模型的动画和可视化 ,探讨了实现动画和可视化方式的机理。文中还描述了动画和可视化的播放和调用模式 ,以及实现这两种模式所遇到的技术难点。仿真模型与动画 /可视化模型间的通信方法也被提到
目前 ,许多大专院校信息管理专业相继开设了多媒体课程 ,但该课程至今仍没有统一的教学大纲。作者认为信息管理专业作为非计算机专业 ,它的多媒体课程应少钻研多媒体技术的硬件知识及理论研究 ,而应多学习软件应用方面的知识。如 :工具软件的使用及应用系统软件的开发方法等。同时 ,对多媒体硬件产品如何挑选购置也要有所了解。据此提出了信息管理专业的课程教学内容应分为两大部分 :基础知识部分和应用系统部分。
