Under the framework of crystal slip theory,a θ model that can describe the anisotropic creep of Ni-base single crystal(SC) alloy was built by the θ mapping method to the crystal directional problem of Ni-base single crystal turbine bladecreep.
针对镍基单晶涡轮叶片蠕变的晶体方向性问题,运用θ映射法,在晶体滑移理论框架下,建立了能够描述镍基单晶合金各向异性蠕变的θ模型。
3) θ-continuous mapping

In this paper,the concept of θ-compact space characterized in terms of special cover and filter is given,properties of semiregularization of θ-compact space and θ-continuous mapping are discussed,and it is proved that a product of a compact spaceand a Hausdorff θ-compact space is θ-compact.
本文给出了θ-紧空间的概念,并用特殊的复盖和滤子加以刻划,讨论了θ-紧空间的半正则化和θ-连续映射,证明了紧与Hausdorffθ-紧空间的积空间是θ-紧的。
4) θ continuous mapping
θ-连续映射

By the use of methods of semantic in logic, some properties of them are discussed, and four equivalence conditions of θ strong continuous mapping and four necessary conditions of θ continuous mapping are obtained.
在不分明化拓扑空间中，给出了人们广为关注的拓扑学中的θ闭包的概念，并由此定义了θ－开集、θ－闭集、θ－连续映射和强θ－连续映射。
