Research on the deviation control method of the number of good eggs of bombyx silkworm eggs ' samples 桑蠶種樣本良卵數(shù)偏差控制方法研究
Deviation control method to samples of number of eggs in percentage of good eggs of silkworm , bombyx mori 桑蠶種良卵率調(diào)查中樣本間卵粒數(shù)的偏差控制方法
Based on the basic function of fea , the iterated formula of modulus of elasticity is deduced through mathematical method as deviation control rule 從有限元基本方程出發(fā),采用最小二乘法作為誤差控制準(zhǔn)則,推出彈性模量的迭代式。
In this essay the technique of the structure calculation and error adjustment measures used in bridge construction prefigurative deviation control was researched based on the construction control and monitor project of wuhan caidian han river bridge 本文主要結(jié)合蔡甸漢江公路大橋的施工監(jiān)測監(jiān)控項(xiàng)目,研究施工預(yù)拱度控制的結(jié)構(gòu)計(jì)算和誤差調(diào)整方法。
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(duì)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(duì)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。
