For technique, the BC junction should be shallow junction diffusion to enhance the sensitivity to light. 工艺上要使BC结为浅结扩散,以增强检测波长光的敏感性。
Based on the priciple of the method of fractional steps, the two dimensional shallow equations arc divided into two parts of advection and diffusion. 本文根据分步法原理,将平面二维不恒定流方程分成对流、扩散两个部分。
There exist three hypotheses on the flow of pore fluid and transport and precipitation of silica, that is, the hypothesis of cycle of shallow underground water, the hypothesis of high concentration of fluid driven by compaction and the hypothesis of diffusion and recycle of local fluid. 而关于孔隙流动与硅质搬运和沉淀有三种假说,即:浅部地下水循环说、压实驱动流体高度集中说、扩散和局部流体再循环说。
Derivations of shallow water wave equations and suspended sediment diffusion equations by method of multiple scales 应用多重尺度法推导浅水波方程和悬沙扩散方程
There are the phreatic flow which shallow cycles and fissured diffusion flow deeply cycling, both are effected more or less by the reservoir water existed in the water-bearing block of limestone. 石灰岩含水体中存在着受库水影响较大的浅循环潜水流和深循环裂隙扩散流。
The fissures and small conduits in limestone are well developed along the fault F2. 2.There are the phreatic flow which shallow cycles and fissured diffusion flow deeply cycling, both are effected more or less by the reservoir water existed in the water-bearing block of limestone. 石灰岩中的溶蚀裂隙和小管道沿着F2断层发育。2.石灰岩含水体中存在着受库水影响较大的浅循环潜水流和深循环裂隙扩散流。
New n  ̄+ p Shallow Junction Formation Method by Using Solid State Epitaxial CoSi_2 as Diffusion Source 固相外延CoSi2薄膜作为扩散源形成n~+p浅结技术研究
Add control condition such as rainfall dripping, under the impact of it, the range of heavy metal migration becomes larger; dispersion effect plays an important part in shallow soil; with the depth of soil becomes stronger, the status of diffusion plays the dominant role. 增加控制条件雨水淋漓时,重金属在雨水的冲击下,在土壤中的浓度迁移范围增大,在土壤浅层机械弥散作用较强,随着土壤深度的增加,扩散作用占据了主导地位。
