Many factors regarding the modifying coefficients of circular and rectangular section are analyzed : ( 1 ) it is theoretically proved that the diffusion coefficient of cl - in concrete is dependent of modifying coefficients ; ( 2 ) through analysis of the results of numerical value calculation, it is discovered that the relation between the modifying coefficients and the thickness of protection layer of concrete is linear, from which the function expression of these two variables is gain ; at the same time, the influence on modifying coefficient of the radius of circular section and the thickness of cl - on the surface of concrete ; based on these, practical calculating method of beginning corrosion time of steel of circular section is set up ; ( 3 ) to rectangular section, the diffusion of cf in concrete is two - dimension diffusion
討論了影響矩形截面以及圓形截面修正系數的因素: ( 1 )從理論上證明了氯離子在混凝土中的擴散系數與修正系數無關; ( 2 )通過圓形截面數值計算結果的分析,發現圓形截面修正系數與保護層厚度基本成線性關系,並建立了二者之間的聯系;分析了圓形截面半徑、混凝土表面氯離子濃度對修正系數的影響,從而建立了圓形截面鋼筋初始銹蝕時間的實用計算方法; ( 3 )在矩形截面氯離子侵蝕下,混凝土處於二維擴散狀態。本文通過計算分析,證明二維擴散的影響區域從邊角開始向中間逐步擴散,並證明了二維擴散影響區域依賴于氯離子擴散系數與氯離子擴散時間的乘積。In this paper, some investigation and design as following. have been carried out on er - yb codoped phosphate glass waveguide laser first, three primary performance parameters of er - yb waveguide laser pump threshold power ; output power and slope efficiency have been commulated and analysed theoretically based on er ~ ( 3 + ) - yb ~ ( 3 + ) energy configuration ; rate equation of stable state and transmitting equation. the influences of er - yb ions concentration ; enabled waveguide length ; light dot radius of signal light and pump light ; reflectivity of output lens on three above parameters have been researched
首先,從er ~ ( 3 + ) - yb ~ ( 3 + )能級結構出發,結合激光穩態速率方程與傳輸方程,對鉺鐿波導激光器的三個主要性能參數:閾值功率、輸出功率、斜率效率作了理論計算分析,並研究了鉺、鐿離子濃度、光波導激活長度、信號光與泵浦光光斑半徑比例、輸出耦合鏡反射率對這三個關鍵性能參數的影響。Found there is relativity between max effective activation wavelength k and ion radius of photochromic compose in photochromic glass, and there is no relativity with based glass
發現光致變色玻璃的有效激活波長最大值_ m值與光敏相組成中離子半徑的大小相關,與基礎玻璃的組成沒有明顯的關系。The diffraction peak angle does n ' t change obviously as co / fe ratio, it is attributed to the radius of co fe ions are fairly similar, so the influence of substitutions on unit cell is small
而隨著co fe比的變化,衍射峰角度值變化不明顯,這是由於co 、 fe離子半徑相差不大,它們之間的位置取代對晶胞的整體影響相對較小。Moreover, the diffraction peak shifts toward high angle as sr content increases. it is ascribed to the substitution of la3 + by sr2 + in lscf increases the average radius of a ions and causes a charge imbalance
且隨著sr含量的增加,衍射峰值向高角度方向稍有偏移,這是由於低價sr ~ _ ( 2 + )取代高價la ~ ( 3 + )增加了a位離子的平均半徑,同時引起電荷不平衡。The result suggest that if there are enough distance combined by every site, the radius will be more accurate. the coherence method was mentioned early ( ota kulhanek, 1973 ) but no one used it to confirm redius of a seismic array
結果證明,只要臺陣各勘址子臺能夠組合出較連續的距離值,則利用相干函數所求得的半徑將更加精確。The boundary radius of an atom ( ion ) is defined by the classical turning point equation ( ( r ) = - i, where i denotes the first ionization potential of the atom ( ion ). the boundary radii of atoms and ions of elements from first - to fifth - row in the periodic table are obtained
對于中性原子,假設此時的能量等於其第一電離能i的負值,即v ( r ) = - i 。我們定義原子核到r的距離為原子的內稟邊界半徑,簡稱為邊界半徑。分享友人
