Waves break once they swell to a critical height, before cresting and crashing into a spray of droplets and bubbles. These waves can be as large as a surfer’s point break and as small as a gentle ripp...
Clusters of solutions and replica symmetry breaking in random k-satisfiability
Random formula decomposition quantity index

糙米三点弯曲破碎力学性能试验分析（Experiment Analysis on Three-point Bending Breaking Force of Brown Rice）
糙米 腹部 背部

分别以糙米的腹部、背部作为承压面，对糙米的三点弯曲破碎力学性能进行了测试。测试结果表明，籽粒腹部、背部的三点弯曲破碎力和破碎力的分布特性存在一定的差异性，即腹部作为承压面的破碎力分布区域较分散，呈现多峰分布，而背部作为承压面的破碎力呈现集中分布的特性；腹部作为承压面的抗弯强度和弹性模量均大于背部，而其断裂能却小于背部。糙米的加工品质与其三点弯曲破碎力学性能之间亦存在一定的相关关系。
