It all started in 1994 when dr . masaru emoto took samples of water from various sources , froze a few droplets , examined them under a dark field microscope and photographed them 自1994年起,江本博士便從各種水源中采取水樣本,再凍結(jié)水樣本中的若干水滴,然后在暗室中的顯微鏡下觀察它們,并拍攝存證。
The method takes advantages of the minimum structure risk of svm ( support vectors machine ) and the quickly globally optimizing ability of pso ( particle swarm optimization ) , the mapping relation between the contents of typical components of groundwater ions and the geology hydrological classes may be set up quickly , by learning from samples of water resources 該方法利用支持向量機(jī)結(jié)構(gòu)風(fēng)險最小化原則和粒子群快速全局優(yōu)化特點,通過對水源樣本的學(xué)習(xí),可以快速自動建立典型離子化學(xué)組分含量與其所屬巖層類別之間的映射關(guān)系。
The plants growing on the land surface can be affected by the occurrence and movement of water and salt in the aeration zone . in order to understand the characteristics of occurrence of water and salt in the aeration zone , we installed three tensionmeter systems . which includes 35 ceramic cups , in the soil of ejnqi oasis on the downstream of heihe river in inner mongolia province . the moisture potential distribution in aeration zone was observed , and the samples of water and soil were collected along the heihe river 為了了解綠洲包氣帶水分、鹽份的分布特征,我們在黑河下游的內(nèi)蒙古額濟(jì)納旗綠洲安裝了3組35支負(fù)壓計,觀測包氣帶中的水土勢,并沿黑河河谷從下游的額濟(jì)納旗到中游的張掖采集土樣和水樣,測試土壤的易溶鹽和潛水的化學(xué)成分,從包氣帶中水土勢和鹽份兩個方面來研究干旱地區(qū)水分和鹽份在包氣帶中賦存和運移規(guī)律。
