aging step
解釋
老化階段-
Several materials with large coefficient of expansion were selected to make packaging components, and it was found that the packaging materials have good temperature sensitivity and compatibility with optical fibers. experimental accuracy and repetition of fbg temperature sensitivity and compensation were discussed. have selected several materials which has bigger coefficient of expansion to do packaging components, have made many temperature experiments, there have not flaws, such as aging, crackle, absciss layer, packaging materials have good temperature sensitivity and compatibility with optical fiber ; have designed the simple and practical packaging components, have performed a serials of experiments about accuracy and repetition of fbg wave - length, have obtained the first step conclusion ; have analyzed the result and made comparison between the result of different experiment, have summarized the best packaging effect and several rules to reduce mistskes
本文所做的主要工作包括以下幾個內容：一、選取了常見的熱膨脹系數大的材料製作封裝元件，經過多次一80到80反復測試，封裝元件沒有出現老化開裂、封裝裂紋、空洞、離層等缺陷，封裝材料具有良好的溫敏穩定性及復用性，與光纖相容性較好；二、對光纖光柵進行簡單、實用的封裝處理，就封裝效果的優劣性、波長測量的準確度、重復性和封裝時產生的波長損失等方面進行了一系列的實驗，得出了初步的結論；三、對溫敏和溫度補償式封裝的實驗數據進行了詳細的分析和對比，從數字上對溫變過程中光纖光柵中心波長的改變及溫變曲線進行了定量的分析，在大量實驗數據分析結果的基礎上，總結出哪種材料封裝效果更好，以及如何有效的減小實驗誤差。 -
Hereafter being the forecasting to the old age population coefficient, this text has been applied two kinds of regression model, namely univariate linear model and logarithmic model, and thought over three kinds of economic speed of development ( high, middle, low ) in the logarithmic model to forecast the old age population coefficient respectively. finally, by analyzing the forecasted value and the inertia law of population development, the paper points out the lengthening of the population equally expected life span will push forward the aging of population step by step to the advanced age development ; the development trend of the population aging continues to be clear, and just appears a stage characteristic ; furthermore, the population aging speed in rural area will be faster than in the city
此後是對老年人口系數的預測，本文應用了兩種回歸模型，即一元線性回歸模型和對數擬合模型，並在對數擬合模型中考慮了經濟發展速度的高、中、低三種方案，對老年人口系數分別進行預測；最後在分析預測值和人口發展慣性規律基礎上對山東省未來人口老齡化發展趨勢作了較深入分析，指出人口平均預期壽命的不斷延長，將逐步推動人口老齡化向高齡化發展；人口老齡化繼續發展趨勢明顯，且呈現出階段性特徵；農村人口老齡化速度將快于城市。 -
The main contents are as follows : 1 ) 3 eliminate error criterion method and step wise regression analysis method is used to analyze the errors of observation date. in the stepwise regression analysis, aging, loading and temperature which bulkily affects the dam ' s vertical deformation are selected as the regression factors, then regression equation and curve of each point are worked out
運用3準則剔除誤差法和逐步回歸分析法對茅坪壩的觀測資料進行誤差分析，在逐步回歸分析中，選用對壩體豎向變形影響較大的時效、施工加載和溫度作為回歸因子，求出各測點的回歸方程和擬合曲線。
