The complex estimative method of telecom customer satisfaction based on ahp 基于層次分析法的電信客戶滿意度的綜合評價方法
The influence of climate , service condition and curing time on durability is analyzed . the relationship between cost and estimative failure cost is discussed 研究了結(jié)構(gòu)耐久性與氣候、使用環(huán)境、養(yǎng)護(hù)時間的關(guān)系,以及估算失效費(fèi)用對結(jié)構(gòu)成本的影響。
First by estimative calculation the final boundary condition can be gained , then the accurate result of three - dimension temperature field and stress can be gotten through placing accurate boundary condition 得到了三維溫度場和應(yīng)力場數(shù)據(jù)結(jié)果。在計算過程中采用了根據(jù)實測值反算的思路,使計算得到的溫度場有可靠的實驗依據(jù)。
Comparatively , the funds industry in china started too late . consequently , the research of the fund hasn ` t formed a complete system . as a result , when we came to the estimation of the funds , we usually adopted the abroad ripe estimative index 相對而言,我國的基金業(yè)起步較晚,而基金業(yè)績的研究在我國還未成體系,在評價我國基金業(yè)績表現(xiàn)時,多采用國外已成熟的評價指標(biāo)。
In this paper , error sources and the relation between error source and transmission error of harmonic gear drive are deeply analyzed based on its working principle and structure . then synthesize these errors by using stochastic error theory to write out estimative formula that calculate transmission error 本文重點(diǎn)對諧波齒輪傳動的運(yùn)動精度進(jìn)行分析研究,從諧波齒輪傳動運(yùn)動誤差的產(chǎn)生入手,首先對誤差源進(jìn)行了深入分析,然后對運(yùn)動誤差進(jìn)行了分析和綜合。
