The replacement of SF6 by refrigerant is under development. For example, R143a by AMC and FK by 3M Co. used as protection gas are both classified as HFC with short atmospheric lifetime and are easily to be decomposed into hydrofluoric acid, carbon monoxide and fluoric carbon monoxide at room temperature.

目前发展中的替代性保护气体以冷媒类为主，如澳洲AMC所采用的R134a及美国3M公司所开发的FK气体，两者都属於氟氢碳化合物，不过其半衰期短，即使在常温下，仍极易分解成氢氟酸、CO、COF2等，其中氢氟酸为有害物质，但因含量很少，且在高温下易与镁液反应，故对人体的为害很小。

We present an efficient approach for generating the correspondence between two homeomorphic 3D polyhedral models. The user can select vertices on the polyhedra to decompose the boundary of each polyhedron into the same number of morphing patches. Further, the user can specify the feature points on the morphing patch pairs to improve the morph. After the morphing patch pairs are be mapped to 2D regular polygons, they are merged and reconstructed to generate a morph. In the main procedures of our approach, we propose an easy mapping method and a foldover-free warping technique. And we also propose a most efficient merging algorithm. The merging can be completed in O.

我们的对应演算法主要的流程架构是(1)设计一套良好的介面提供给使用者在物体表面上点选圈选点；(2)利用最短路径将圈选点作两两相连，以切割勿体表面；(3)利用Relaxation的方式进行摊平的目的；(4)利用Warping技术以增进使用者的便利性，因此无须圈选太多快patch以精确对齐物体的特徵，同时还提供一套自行避免相交情况的演算法以保证不相交；(5)我们研发出一套极快速的merge演算法，其利用最小轮廓涵盖结构而有效地达成区域搜寻与区域merge，因此在效率上达到O；(6)最后藉由Remesh与3D位置资讯的建立，重构出对应的结果整体而言，透过本论文所研发的对应演算法将不用花费太多的执行时间，因此符合经济效益。

Small cell carcinoma is a rare, highly aggressive and invasive poorly-differentiated neuroendocrine carcinoma that is often in the lungs but rarely in the head and neck region. It is even rarer to occur in the hypopharynx. As a highly malignant lesion, it tends to metastasize early and readily.

小细胞癌是一种少见但极具侵犯性之分化不良的神经内分泌癌(poorly differentiated neuroendocrine carcinoma)，它常发生在肺部，而在头颈部非常少见，至於下咽部的病例数，更是寥寥可数。

At the same time the design becomes an iconographic building, as the small individual houses are interconnected by a sculptural roof structure.

同时该设计的每个小房子通过雕塑化的屋顶结构彼此相连，极具图案标识性。

装置在响应速度较高的同时具有较小的过调，且有极好的鲁棒性。

And the results indicate that the principal stress directions in study area are mainly NE-SW, and the second substage tectonic twist made the direction deflect from North to East, but the primary direction changed little; tectonic activities during the O〓～S～D stage is some violent, most of the area are under high stresses status, and rock fracture degree is correspondingly higher, as coinciding with the drill cores observation, i.

通过数值分析，模拟了塔中Ⅰ号断裂带和塔中45井三维模拟区O〓灰岩的构造应力场和应变场，结果表明：研究区主应力方向为北东～南西向，第二期的构造扭动使其由北向东发生了一定的偏转，但总的方位变化不大；O〓～S～D时期，塔中地区构造运动较强，研究区大部分处于高应力状态，岩石破裂程度较高，而岩芯观察结果也证实了这一结果，即O〓灰岩地层中早期形成的构造结构面比较发育，单个结构面的规模也较大；C～P时期，岩石的破坏程度较早期有所提高，主要表现在两个方面，一是各局部区岩石的破坏程度普遍有所提高；二是各个级别破裂区的分布范围相应地扩大了；研究区应力分布表现出明显的不均匀性，特别是剪应力，无论是O〓～S～D时期，还是C～P时期，都有很大的差异性，特别是在小断层的端部，剪应力比较集中，而且在断层的两盘，剪应力方向和大小都变化极快。
