Updating the gis by the traditional method is to input the data by hand and needs practical surveying to get the geographical information . this approach consumes too much time and produces little effect, so gis can not be updated in time 在對gis系統(tǒng)的數(shù)據(jù)更新過程中,如果遙感分類提供的地理信息精度不高,那么用遙感數(shù)據(jù)來更新gis數(shù)據(jù)就失去了意義。
Secondly, combining practical survey method and time-resistance mathematic model, the author obtained average time distance from every time-cell to fictitious time center, isotime curve figure ( by arc view 3d analyze ) and temporal shape 然后利用實(shí)際測量法和理論公式法計(jì)算出深圳特區(qū)各時(shí)間單元的平均時(shí)間距離,并用arcview中的3d分析模塊自動(dòng)生成等時(shí)線圖。
Two practical survey data sets are used as a case study to verify the efficiency and reliability of the compensation method . the results show that the precision of the compensated network has been increased from 2.74mgal to 7.11magal . 4 平差結(jié)果表明三種平差模型均對測線系統(tǒng)誤差進(jìn)行了有效的補(bǔ)償,補(bǔ)償后的精度提高了2.747.11毫伽,而且,對補(bǔ)償后的測線網(wǎng)進(jìn)行測線系統(tǒng)誤差顯著性檢驗(yàn),檢驗(yàn)結(jié)果顯示測線系統(tǒng)誤差的影響已不再顯著。

Then on the basis of calculating result from the prefigurative deviation control structure calculation, " rational data forecast processing about error adjust in prefigurative deviation control was made by the prefigurative theory of bp neural network and corresponding program and software matlab6.1 . at last via the data comparison with the practical survey data draw a conclusion : it is feasible for the construction prefigurative deviation control and error adjust used in pc rigid frame bridges to use the calculation model and program brought forward in this paper 同時(shí),在對預(yù)應(yīng)力混凝土剛構(gòu)橋施工過程線形預(yù)拱度控制的結(jié)構(gòu)計(jì)算分析的基礎(chǔ)上,利用bp神經(jīng)網(wǎng)絡(luò)的預(yù)測理論和相應(yīng)的程序及軟件包matlab6.1對預(yù)拱度控制中的誤差調(diào)整進(jìn)行了較好的預(yù)測處理,通過與實(shí)際施工數(shù)據(jù)及成橋后測量結(jié)果作分析比較,得到結(jié)論:運(yùn)用本論文的計(jì)算模型和程序?qū)︻A(yù)應(yīng)力混凝土剛構(gòu)橋預(yù)拱度控制過程進(jìn)武漢理工大學(xué)碩士學(xué)位論文行結(jié)構(gòu)分析和誤差調(diào)整處理是可行。
To solve real problem aiming at real environment, i have chosen a pint-sized supply chain composed of two sticking points as my research samples, investigating two companies to find out the crux in their actual supply chain operation . chapter 6 and 7 state effective solutions of lean supply chain strategy basing on these practical surveys 要成功地實(shí)施敏捷供應(yīng)鏈管理,使供應(yīng)鏈管理真正成為有競爭力的武器,就要拋棄傳統(tǒng)的管理思想,把企業(yè)內(nèi)部以及節(jié)點(diǎn)企業(yè)之間的各種業(yè)務(wù)看作一個(gè)整體功能過程,形成集成化供應(yīng)鏈管理體系。
By choosing 358 junior school teachers in 10 rural schools in five towns as the independent sample; adopting the " scl-90 symptom measure form " and the self-made " invetigation paper on teacher'mental health reason " as survey tools; using the three methods-measurement, investigation and interview in an integrated way, the aothor made a practical survey to the mental health conditions of the teachers in rural junior schools in zhangye district 本研究選擇了張掖地區(qū)所轄的五縣市共10所農(nóng)村初中的358名教師作為獨(dú)立樣本,采用“scl?90癥狀測評(píng)量表”和自編的“教師心理健康成因的調(diào)查問卷”為研究工具,將測驗(yàn)、調(diào)查、訪談三種方法相結(jié)合,對張掖地區(qū)農(nóng)村初中教師心理健康狀況進(jìn)行了實(shí)證研究。
