弹性半空间；本文用线载荷积分方程法研究嵌在弹性半空间的刚性变直径圆轴的轴对称扭转。利用将"半空间的点环力偶"这一虚的基本载荷沿对称轴的圆轴区间中分布就能使本问题归结为一个一维的非奇异的Ferdholm第一种积分方程，且很易用数值求解。文中给出刚性圆锥，圆柱，圆锥柱嵌在弹性半空间的扭转的数值计算的例并和他人的已知结果相比较。

Since polar organic crystals have noncentric structures, the existence of polar axis in the crystals has a significant effect on the molecular arrangement and on the crystal growth.

极性有机晶体在不同的溶剂中具有明显不同的生长习性，主要有两个方面的原因：一是极性有机晶体属非中心对称性晶类，晶体具有极轴，极轴的存在对分子堆积和晶体生长具有重要影响；另一是极性有机晶体的界面结构不同，溶剂与晶体界面的相互作用不同，使得晶体同一面族的生长速率不同，从而导致了晶体习性的改变。

We initiated a genetic screen for Drosophila olfactory genes by means of SG18.1-Gal4/UAS system: The result validates our screen as an rapid, effective approach for recovering genes controlling glomerular map patterning; From a misexpression screen of 1,515 P{GS} lines, we identified 23 genes that, when forcibly expressed in the olfactory receptor neurons, disrupted the stereotyped anatomy of the Drosophila antennal lobes; These genes, which have not been shown previously to control olfactory map development, encode novel proteins as well as proteins with known roles in axonal outgrowth and cytoskeletal remodeling.

本文首次利用SG18.1-Gal4／UAS基因筛选系统对果蝇嗅觉基因进行了筛选和鉴定：结果表明，所采用的方法可以快速、有效地分离到果蝇嗅觉相关基因；从1515株果蝇P{GS}品系分离到86株突变体，其中40株有明显表型，从中鉴定了23个基因，这些基因在ORN强迫表达时可以损坏果蝇嗅叶的固有结构；在筛选中发现的一些调节嗅觉图谱发育的基因可以编码新蛋白或编码参与轴突生长和细胞骨架重塑的蛋白；为了便于研究，根据基因的功能和所编码蛋白的特点，我们对分离到的基因进行了分类，即参与轴突引导和突触产生、调节转录、调节细胞骨架和功能未确定或未知的基因；并通过对嗅觉感觉器的检测发现，除了调节转录的基因外，其他基因对触觉器的数量和分布影响不明显。

The flexible shafts have better strength and rigidity than ordinary level, they are ideal substitute for conventiona level and universaljoint with such merits as : light weight, good flexibility, easily crooking, compact constru—ction, easily installation, good seal, proof rust and anti—deformation, neatly operation.

工作原理：机械操纵系统中的连接部位受力位移时，软轴的芯轴受力，产生往复运动，形成拉力、推力驱使机械作换挡、取力、升降、行走、加油、熄火、制动、转向、换向等工作，它不但优于一般杠杆的强度、刚性而且重量轻、柔性好、可弯曲、结构紧凑、安装方便、密封性好，不易锈蚀变形，操作轻便灵活，是替代传统的连杆、万向节机构的理想产品。

On the basis of the cultural axis, in the city's brain----the Citizen Center, there forms the guide idea for the city's development and construction, while the Citizen Plaza is revealed as that the guide idea sublimes to be a great power which could promote the society after melting with the suggestions and advices of the populace. This power grows with the green river and becomes stronger and stronger, passing by the south plaza and south main axis in the center plaza, finally reaches the climax area----the conference and exhibition center, the display district for the society's productive forces.

在文化轴的基础上，城市的大脑－市民中心产生城市发展建设的指导思想，市民广场则表达为这种指导思想在与来自四面八方的群众的意见和建议融汇后，升华成为可以推动社会进步的力量，这股力量随着绿河成长，由弱变强，其间经历了中心广场南广场和南中轴（市民休闲和商业活动复合区），最终到达了高潮点——会展中心，即社会发展力水平和社会财富的展示区。

It's Animated films have been a codeword about dream and joy to children for a long time. But Is It always happy This research focus on "Finding Nemo" that the top-grossing one of Disney's Animated films. According to Semiotics, author use the Paradigm Axis and the Syntagm Axis to analyze structural relationships of signs then to infer the connotation of characters in the text. According to the above, author analyze the images of violence characters in animated films.
