大多数语言实现都假设事务中执行的代码是单线程的，但是隔离和并发是两个互不影响的概念（ Amdahl 定律将受到多核的冲击）。

Most implementations (hw or sw) assume code inside a transaction is single-threaded, but isolation and parallelism are orthogonal (and Amdahl’s Law will strike with manycore)

冲击波的破坏伤害作用主要取决于峰值超压的大小，立方根比例定律是定量估算冲击波超压最常用的方法。

The damage of shock wave mainly depends on peak overpressure and scaled cube root distance is the most common method to estimate the shock wave overpressure.
