The present paper falls within the scope of three historical phases, Japanese Colonial Period, Post-hostilities Period and contemporary relevance; it takes diachronic Luan-tan Opera audio materials in the same play for the research theme, cuts into the angle with vernacularism, attempts to observe the varieties of language changing while these troupes were trying to fit in the environment.

本论文以日治、战后及当代三个历史段落为范围，选择跨越两个时空以上、相同剧目的乱弹戏有声资料为研究题材，并以戏曲剧种的白字化为切入视角，试图观照戏曲剧种适应环境所因应的变异性，即「剧种语言」在地化的现象。

To explore the possibility that the androgen may facilitate differentiation of hair follicle stem cells into sebocytes, we carried out experiments to test this hypothesis. The concrete steps to carry out this research were as follow: Firstly, observed the expression of AR and examined the expression of AR mRNA of rat vibrissa follicle stem cells in vivo in three defined phases of a hair follicle cycle, including anagen, catagen and telogen. Secondly, cultured HFSC deprived from vibrissa follicle bulge region in culture flasks and observed the expression of AR, ketertin 15 (K15), cluster of differentiation 34 (CD34) andβ1-integrin of those cells.

为了探索雄激素对毛囊干细胞定向分化为皮脂腺细胞的过程是否具有促进功能，我们进行了如下的实验来进行研究：第一步，检测了在毛囊周期的三个不同时期(生长期、退化期和静止期)中大鼠触须毛囊干细胞中AR、ARmRNA的表达以及检测原代培养的毛囊干细胞中AR的表达并探讨意义，为进一步研究打下基础。

热采作为一种有效的稠油开采方式虽然被广泛采用，但其开采成本相对较高；而出砂冷采作为一种低成本的稠油开采方式，近年来已经在稠油油藏的开发中得到很好的应用。

For vortex-liquid phase,the E-J relation could be described according to the Kim-Anderson model:U=U0(1-J/JC).While for vortex-glass phase,the electric field decays verydramatically with decreasing current density,so it is difficult to be observed with theinstrument has limited precision.In the intermediate current region,the E-Jrelations of the both phases could be fitted in terms of a phenomenological model:U=(U0/μ)[μ-1],it was concluded that the sign of μ-value changes fromnegative to positive when the temperature decreases lower than the glass-transitiontemperature Tg,meanwhile,the activation energy U enhances dramatically.Whilein the large current region,Zeldov's logarithmic model was suitable for fitthing theE-J curves of the both phase.Moreover,there was no abrupt change of U or thecharacteristic current density IC.However,the effective radius of vortex line variesremarkably around Tg.

对于涡旋液体相，小电流区的E-J关系可以用计及反跳的Kim-Anderson模型U＝U0(1-J/JC)来描述，而对于涡旋玻璃相，小电流区的电场随电流密度减小而迅速衰减，以致很快脱离了实验测量精度的范围；在中等电流区，两相的E-J关系可以用共同的唯象过渡模型U＝(U0/μ)[μ-1]来拟合，得到在玻璃转变温度Tg两侧μ值由正到负的变化，同时激活能U在Tg以下迅速升高；在较高电流区，两相的E-J关系可以很好的用Zeldov对数模型来描述，拟合结果表明U在Tg两侧的趋势没有明显变化，但是涡旋线的有效半径发生了显著变化。

Such a viewpoint of the effects of a little water addition has never been reported, it opened a new way to product SWCNTs with high purity and low cost. On the ground of the experimental results and mechanism studies, a little water addition may open a way for using the natural gas as carbon source to manufacture SWCNTs. By analyzing XRD, XPS results and with comparative experiments, we concluded that the active phases of SWCNTs growth in Ar were small Fe particles. A little W species can improve the surface characters of support and increase the dispersion of Fe particles, but higher W loading will cause large quantity of WC, which decompose CH〓 to amorphous carbon.

本文根据W-Fe-MgO催化剂中间产物和粗产物的XRD、XPS测量结果，结合制备实验和对比实验指出：在Ar中1073K下，生长SWCNTs的活性相是Fe的小颗粒，少量W在催化剂中以氧化物形式对载体表面改性，起提高Fe分散度的作用，但W浓度过高时在反应过程中会生成大量WC，又会催化CH〓分解为无定形碳，造成产物中SWCNTs含量下降。
