tidal datum中文什么意思
例句與用法
- Optimization model of networks " roughness is established . in this model , objective function is the average scedasticity of relative error for water level and discharge . with the recorded water level and tidal data , the value of roughness is optimized
建立了以流量和水位相對(duì)均方差作為目標(biāo)函數(shù)的河網(wǎng)糙率優(yōu)化模型，并利用實(shí)測(cè)的河道水位及潮流資料，對(duì)河道的糙率取值進(jìn)行了優(yōu)化，所建立的糙率優(yōu)化模型更加合理，計(jì)算的效率及精度大大提高了。 - Then , harmonic analysis is done with the newest baytap - g tidal data analyzing software developed by ishiguro and professor tamura , who are working in japan and the eterna34 tidal data analyzing software developed by wenzel , who had worked in german . as a result , the recently observed tidal gravity parameters of jiufeng station are obtained . finally , the ocean loading correction of the observing tidal gravimetric parameters , the temporal synthesized tide , correction of the station air pressure and the polar motion on the gravity residual , the analysis of the final residual , and so on , are investigated
Vauterin研制的tsoft潮汐數(shù)據(jù)預(yù)處理軟件，實(shí)施了觀測(cè)數(shù)據(jù)的預(yù)處理，為超導(dǎo)重力儀觀測(cè)數(shù)據(jù)的國(guó)際資料交換和數(shù)據(jù)分析準(zhǔn)備了修正后數(shù)據(jù)；然后利用由日本ishiguro與tamura研制的最新的baytap - g和由德國(guó)的wenzel研制的eterna34潮汐分析軟件，對(duì)預(yù)處理后的重力潮汐觀測(cè)數(shù)據(jù)進(jìn)行調(diào)和分析，獲得了九峰臺(tái)最近的觀測(cè)重力潮汐參數(shù)；最后討論了觀測(cè)潮汐參數(shù)的海潮改正、隨時(shí)間變化的重力合成潮的構(gòu)制、大氣效應(yīng)改正、極移重力改正以及最終重力殘差的分析。 - At the same time , we introduce the extended range of akp ( ob ) value ( er ( akp ) ) as the relatively objective criterion of checking observational tidal data to get rid of those unreasonable data before resolving the fcn parameters , and it is very important for us to improve the quality of resolving fcn parameters objectively and effectively
這利于我們清晰地分析觀測(cè)資料與解算結(jié)果之間的相應(yīng)關(guān)系。同時(shí)，我們提出er ( akp )作為一種衡量觀測(cè)資料優(yōu)劣的相對(duì)客觀的標(biāo)準(zhǔn)，使我們?cè)诮馑闱熬蜕釛壱恍┎惶侠淼馁Y料。這對(duì)于我們客觀有效地提高解算質(zhì)量是很有價(jià)值的。
