篩下分佈 的英文怎麼說
中文拼音 [shāixiàfēnbù]
篩下分佈
英文
under distribution-
Biodiversity exists among am fungi and is influenced by numerous factors including soil properties and plant species. if am fungi are to be used in sustainable agricultural systems it is necessary to study native am fungi in the target areas and then select efficient isolates that can be applied as inocula in the field to improve crop growth. the objectives of this study were to investigate the germplasm of am fungi, to understand the distribution pattern of am fungi in different ecological conditions such as area, soil factor and host plant, to select isolates effective in nutrient acquisition by the host plant sweet potato, to test their effectiveness under field conditions, and to monitor amf after their introduction into the field
本研究通過調查我國北方部分地區的am真菌資源，研究了am真菌的種群組成及其在空間、土壤利用方式和宿主植物類型等不同環境條件和空間尺度上的分佈規律；在此基礎上，根據它們對甘薯的生長、吸磷效應篩選出高效菌株，在大田條件下研究了am真菌菌絲的分佈特性、代謝活性及其對甘薯產量和品質的影響；並通過分子探針跟蹤調查了引入am真菌在共生體中的發育和表達，以期為菌根真菌的生產應用提供技術支持。The characteristic of stirring equipment is used a shaking sieve to disperse the adding pure fe or fe203 powder and used a combined stirrer instead of a common paddle stirrer to improve the shear effect to mixing melts. the particularity of fabricating process is the step of holding stirring at a constant high temperature. both of which can improve the even distributing degree of reinforcement phase in pure al matrix
攪拌設備的特殊之處在於使用了振蕩篩分散加入粉末和更換組合式攪拌器來提高對混合熔體的剪切效果，工藝的特別之處在於一定溫度下的保溫攪拌過程，這二者均能提高強化相在純al基體中的均勻分佈。However, in the absence of data distribution information, the optimizer will calculate selectivity for filters of different types based on table indexes
然而在缺乏數據分佈信息的情況下，優化器將基於表索引計算不同類型篩選器的選擇性。Abstract : the paper mainly introduces how to optimize the existed filtration method with statistics normal distribution and quadrature optimization, which make the optimized filtration method economic 、 time saving and effective
摘要：主要介紹了如何利用正態分佈和正態優化對現有的篩選方法進行優化，從而使優化后的篩選方法在達到預期篩選目的的情況下做到最經濟，省時和有效。分享友人
