解釋
離均差-
Standard deviation in statistics, a measure of the dispersion of a frequency distribution : it is the average magnitude of deviations from the center of normal curve, calculated by squaring all the deviations, calculating their mean, then finding the square root of the mean
標準偏差：統計中，一種衡量數據組分佈的分散或變化情況的數據，是偏離正態分佈中間位置數據大小的平均值。 -

所建模型可以利用當地常年氣象資料（ 30年平均值，如月平均氣溫、月平均最高和最低氣溫以及月日照時數、緯度） ，確定不同地區、產量水平與品種最適葉面積指數動態，為小麥數字化栽培提供科學依據。 -
It can be seen from the measuring results that the deviation is litter than 10. 1 % when the estimate value of the nature radiation ' s kerma is compared to the average value gotten by standard ionization chamber, and the deviation is less than 16. 2 % when the estimate value of two groups of tlds those measuring radiation in laboratory is compared to the conventional true value in standard radiation field
從參比單位給出的測量結果看出，天然環境輻射比釋動能測量的評定值與標準電離室測量的平均值比較，其偏差好於10 . 1 % ，實驗室射線照射組兩組熱釋光劑量計（ tld ）測量評定值與標準輻射約定真值偏差好於16 . 2 % 。 -
This paper precedes analysis by examples on investment income in shanghai and shenzhen stock market from 1994 to 2005 by investment strategies with financial ratios as decision basis, inspecting average rate of return of various investment strategies, standard deviation for investment income, sharpe ratio of reward to risk, and analysis on these results. financial ratios in research include : price - to - book ratio, price - to - earnings ratio, price - to - sales ratio
本文主要對以相對估價法為決策依據的投資策略在滬深兩地a股市場1994年至2005年的投資收益進行實證分析，考察各種投資策略在這11年間的總收益、年度復合收益率、收益標準差、收益的夏普風險指數，並對結果進行了分析。 -
Three characteristic features, such as average velocity of sound, deviation coefficient of sound velocity, and deviation coefficient of amplitude are extracted from four kinds of testing data which are sound velocity, amplitude, frequency and waveform in this paper. fuzzy analysis and artificial neural network are combined to form an intelligent system with similar functions to human brain to classify grc, aerated concrete, hollow brick, solid brick and concrete block. the accuracy of this system is up to 95 % in field tests
由超聲脈沖法獲得4種檢測信息聲速、波幅、頻率和波形，從中提取3個特徵量：平均聲速、聲速的離差系數和波幅的離差系數，利用模糊分析方法和人工神經網路相結合對grc 、加氣混凝土、空心磚、實心磚、砌塊5種墻體材料進行種類識別，形成一個智能化的、具有類似人腦功能的系統.經現場實測證明，判別的準確率達95 %以上。 -
The results show that, for reynolds number of 4400 ~ 23800, heat transfer coefficients at stagnation point always increase with the increasement of reynolds number ; the average deviation of heat transfer coefficients at stagnation point from published results is about 10. 8 %, which shows the system is reliable for temperature measurement
實驗結果表明，在re = 4400 28300范圍內，駐點區換熱系數隨雷諾數的增大而增大；駐點區換熱系數與前人的實驗結果相比平均誤差10 . 8 ，實驗系統具有很好的可靠性。 -
It can be found that the two models can measure the credit risk better and their numerical values of the var are relatively close, which means that at a certain confidence level, the portfolio ' s maximum loss calculated under the default model is familiar to the maximum loss in value resulted from the credit metrics model. however, under the default model the standard deviation of the loss of the loan is a bit more than the one which deviates from the average value of the loan under the credit metrics model ; in addition, the conclusion also demonstrates that the two models have some differences in the measuring the capital reserve to some extent
從結果可以看出，這兩個模型均能較好地度量銀行貸款信用風險，其計算所得的var值比較接近，說明在給定置信水平下所能達到的最大損失和所能達到的價值上的損失在數值上是相近的；不過，違約模型下貸款損失的標準差要比creditmetrics模型下的貸款價值偏離其均值的標準差要大些；此外，結論還表現出二者在計量資本金要求上有所差異。
