troad gauge rail,wide gauge

In the traditional design and analysis, beam or thin plate is often chosen as the mechanical model for the concrete slab sleeper.

在传统的设计与计算中，为了简化问题便于工程应用，常选择“梁”、“薄板”作为宽轨枕的力学模型。

With the wide trail strategy used,the cryp-tographic security against the differential and linear cryptanalysis is ensured.

同时在设计中采用了宽轨迹策略,确保算法对差分密码分析和线性密码分析的安全性。
