隔天醒來，透過仲介公司的介紹，我們還是繼續參觀比較不同的房子，就在貸款期限截止前一周，終于找到一間合意的房子，簽約時仲介公司帶我們去見這位屋主，此時我才驚訝的發現，她竟然就是出現在夢中的那位陌生人，這時我才恍然大悟，師父早已為我們安排好了新家。Based on the liquid crystal polymer theory, two kinds of polyacrylates were synthesized by choosing biphenyl group as rigid nucleus of mesophase group and six methylene chain as flexible spacing group. an important chiral additive was synthesized by choosing l ( - ) ~ 2 - octanol as chiral group. mixture was made of the additive and liquid crystalline polymer, which structure was identified by ftit, " ii nmr, dsc and pom
本論文根據液晶分子結構理論，選擇聯苯基作為介晶基元的剛性核、柔性的六亞甲基脂肪鏈為柔性間隔基，與丙烯酸反應，合成了兩種丙烯酸酯型聚合物；以拆分的l （ - ） 2 -辛醇為手性基團合成了一種液晶手性添加劑，並將所合成的手性添加劑與液晶聚合物共混，採用ftit 、 ~ 1h - nmr 、 dsc 、 pom等手段對合成的化合物、共混物進行了表徵。Numerical simulations show that : ( 1 ) owing to the temperature variation resulting in the change of the refractive index of both the semiconductor medium and the fi ber, and further inducing the shift of the longitudinal modes of the fgesl, the lasing wavelength of the fgesl has a shift tendency to longer wavelengths with the increase of the temperature ; the mode hopping happens for a short external cavity and disappears for a long external cavity
數值模擬的結果表明:由於溫度變化造成半導體介質和光纖的折射率發生變化從而導致fgesl的縱模發生移動，因此fgesl的激射波長隨著溫度的升高將存在向長波長方向發生移動的趨勢，對于短外腔， fgesl的縱模間距較大，半導體介質折射率隨溫度的變化程度大於光纖折射率隨溫度的變化程度，因而存在模式跳躍現象;對于長外腔，由子fgesl的縱模間隔很小，因而不存在明顯的模式跳躍現象。Technology of time - interval measurement has been applied in many fields. how to improve its precision is an emergent question. on the basis of analyzing electronic counter ' s principle and error, this paper puts emphasis upon introducing high precision time - interval measurements all over the world. all these methods aim at electronic counter ' s principle error, and obtain special effect. lastly, the progress direction and application foreground of high precision time - interval measurement methods are predicted
