deformation of the arch ring support structure is smaller was validated by monitoring data.───经过监测，采用拱圈支护结构变位很小。
It used ring data structure to save massive data effectively. Bounded error-distances from vertices to average plane were computed to find prime vertices for removal.───采用环形数据结构有效存储大规模数据点，通过计算点到平均平面的有限误差距离进行压缩点判别。
include functional modules, related data structure, frames of message encoding, certificate management database, ring of keys, concrete information flows for access control and so on.───模型的整个可实现框架：包括各组成模块的功能、相关数据结构和消息编码格式、证书管理库和密钥环的设计，以及具体的访问控制流程等。
