As a model, spline interpolation on a uniform tetrahedral partition was used, and the spline coefficients were repeated by the gridded samples 該模型以樣條基函數(shù)為背景,系數(shù)則由周?chē)蓸狱c(diǎn)數(shù)據(jù)重復(fù)迭代產(chǎn)生。
(2 ) calculating the gridded rayleigh wave attenuation factor y and group velocity . the lsqr algorithm is used to inverse the attenuation factor and group velocity under 4 ? x4 ? gridding and 2 (2)進(jìn)行rayleigh波衰減系數(shù)、群速度網(wǎng)格化純路徑衰減反演計(jì)算,得到網(wǎng)格單元純路徑衰減系數(shù)和群速度分布結(jié)構(gòu)。
This approach, using elliptical influence functions, involves the optimum blending of observations from a monitoring network with gridded pollution fields predicted by the complex air quality model tapm 這個(gè)方法使用橢圓的影響函數(shù),并且以最理想的方式混合了監(jiān)測(cè)網(wǎng)的觀察值與復(fù)雜空氣品質(zhì)模式(tapm)所預(yù)測(cè)的污染區(qū)域。
Due to the increase of time interval and decrease of precipitation intensity within a month, no monthly runoff appears in some gridded cells as the xin'anjiang monthly hydrological model is applied to the huaihe river basin 由于計(jì)算時(shí)段加長(zhǎng),雨強(qiáng)均化,導(dǎo)致原新安江月水文模型在淮河流域的應(yīng)用中,網(wǎng)格徑流深出現(xiàn)了大量不合理的零值。
It is the geological data pretreatment to set off cells of geological body and to select model and forecast cells and to pick up and to evaluate geological variable, the evaluated geological cells are finally gridded by gis 地質(zhì)數(shù)據(jù)預(yù)處理,就是在深入研究測(cè)區(qū)的地質(zhì)資料的基礎(chǔ)上,對(duì)地質(zhì)體進(jìn)行單元?jiǎng)澐帧⑦x擇模型單元和預(yù)測(cè)單元、提取地質(zhì)變量并賦值,最后對(duì)賦過(guò)值的地質(zhì)單元利用gis進(jìn)行網(wǎng)格化。
