可防止的

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。

No man was ever so poor that he could express all he has in him by words, looks, or actions; his true knowledge is eternally incommunicable, for it is a knowledge of himself; and his best wisdom comes to him by no process of the mind, but in a supreme self- dictation, which keeps varying from hour to hour in its dictates with the variation of events and circumstances.

没有人是永远这么差，他可以用文字表达他所有，他也期待，或行动，他的真正的知识是永恒的静默，因为这是对自己的知识，以及他的最佳智慧来给他的过程中没有心，但在最高法院自默，这可防止小时不等小时在其与事件和情况的变化驱使。

The tact and skill which suffice to avert a Woman's sting are unequal to the task of stopping a Woman's mouth; and as the wife has absolutely nothing to say, and absolutely no constraint of wit, sense, or conscience to prevent her from saying it, not a few cynics have been found to aver that they prefer the danger of the death-dealing but inaudible sting to the safe sonorousness of a Woman's other end.

在技巧和技能，足以避免一个女人的刺是不平等的阻止女人的嘴任务，并作为妻子绝对没有什么可说的，绝对没有智慧，意识，还是良心约束，以防止它她说，不少愤世嫉俗已发现断言，他们更喜欢的死亡危险性交易，但听不见刺的女人的另一端安全sonorousness。

The results show that potassic salts prevent the transition of Ⅳ-Ⅲ effectively, while oxide, Cu(NO3)2,(NH4)2SO4 and MgSO4 prevent the transition of Ⅲ-Ⅱ, the composite of KCl and ZnO prevent the transition of Ⅳ-Ⅲ and Ⅲ-Ⅱ simultaneously.

结果表明，所采用的钾盐均可有效防止AN发生Ⅳ-Ⅲ相转变，氧化物、Cu(NO3)2、(NH4)2SO4等无机物可有效防止AN发生Ⅲ-Ⅱ相转变，KCl与ZnO的复配物可同时防止AN发生Ⅳ-Ⅲ及Ⅲ-Ⅱ的相转变。
