查询词典 quasi-stationary

The reaction mechanism between nickel ion and butynediols in the electroless plating process was analyzed. The results show that the change of BOZ concentration is a quasi first-order reaction, the change of the nickel ion concentration is related to the BOZ density, and this change belongs to a higher order reaction. The reaction rate equation was determined as dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4. The activation energy of this process decreases as temperature increases, and it decreases with the BOZ concentration as 64-423 mg/L, it increases with the BOZ concentration as 123~240 mg/L. The S value is positively correlated to temperature, when the temperature is 80℃, the reaction rate and S value are the largest; while when the temperature is above 80℃ and BOZ concentration is over 160 mg/L, S value and the reaction rate decrease gradually.

结果表明，镀液中BOZ浓度的变化是准一级反应，镍离子的浓度变化与BOZ的浓度有关，属多级反应，其反应速率方程为dC/dt=-8.585×10^(-4)+1.188×10^(-4)t-4.64×10^(-6)t^2+5.8×10^(-8)t^3-2.3×10^(-11)t^4，反应体系的活化能E随温度的升高而减少，随BOZ浓度的变化而变化：当BOZ浓度在64~123mg/L时，E线性减少；在123~240mg/L时E线性增加。S随温度的升高而增加，当温度达到80℃时S值最大，反应速度最大；当温度超过80℃，BOZ浓度大于160mg/L时，蝎的值逐渐减少，反应速度降低。

At his age when dabbling in politics roughly some score of years previously when he had been a quasi aspirant to parliamentary honours in the Buckshot Foster days he too recollected in retrospect (which was a source of keen satisfaction in itself) he had a sneaking regard for those same ultra ideas.

大约二十年前，就在小伙子这个年龄上，他也曾一头扎进过政治。当鹿弹福斯特在台上的年月里，他对议员这一显赫职务抱着近似向往的态度。他还记起，自己也曾对那些同样的过激思想暗自怀有敬意（这本身就是巨大的满足的源泉）。

The replica material used in this study is Polydimethylsiloxane. The enlargement of replica compared to original size is 2.34%. Since PDMS is transparent, a layer of metal should be sputtered on its surface to measure optical characteristic, however the accuracy will be affected by the metal coated. The result assumes that Sternocera aquisignata, Chrysochroa rajah and Catoxantha opulenta may have one-dimensional photonic crystal structure. The fabrication of quasi-structure with elytra from Buprestid can promote the applications in the field of photonic structure and optical components.

经PDMS翻印的结果，最小仅增加原始尺寸的2.34%，翻印结果良好，但因翻印结果需镀上一层材料，使得镀上的材料严重影响结构的反射率，造成结构不同反射率也类似的情形，将结构刻画在不需镀金的材料上，将可防止镀上材料影响反射率的问题，并将所制成之结构用於防伪、光子结构研究和光学元件上。
