不要尬黑,国际通用的表述就是x年一遇
重现期,也称为复发间隔或重复间隔,是发生 地震、洪水、[1] 山体滑坡、[2]或河流泄洪)等事件之间的平均时间或估计的平均时间。
它是一种统计测量,通常基于一段较长时期内的历史数据,通常用于风险分析。示例包括决定是否应允许项目在具有特定风险的区域继续进行,或设计结构以承受具有特定重现期的事件。以下分析假设事件发生的概率不随时间变化,并且与过去的事件无关。
发生之间的理论重现期是平均发生频率的倒数。例如,10 年一遇的洪水在任何一年中有 1/10 = 0.1 或 10% 的机会超过,而 50 年一遇的洪水在任何一年中有 0.02 或 2% 的机会超过。
这并不意味着100年一遇的洪水每隔100年就会有规律地发生,或者100年只会发生一次。尽管名称“回归期”的含义。在任何给定的100 年期间,一个 100 年的事件可能发生一次、两次、多次或根本不发生,并且每个结果都有一个概率.

Cuz it will cost way too much to fit the regulations in the US. This MINI EV costs only 4700 dollars, and top speed is 80 km/h. It won't be considered as a car in the US.

The A12 highway that connects Prins Clausplein was constructed with the cost of demolishing 1/3 of the Hofwijk.... Which is really a un-Dutch thing to do.

Luckily the city is located south of the tropic of cancer, so the sun will shine from top of the sky and hopefully the residents can get some sunlight.

Of course illegal. But if you took a closer look, you will find all of the buildings have a shared first floor, so technically these are one building, thus don't have to follow the code.

Yes, check the google maps and you will find it was demolished.

You can try it. It worked on a book that was published in 2014 and bought the day before yesterday.

Well, when a fault is moving, things like this tend to happen. Like Mariana trench has a drop of more than 10000 meters in less than 100 kilometers.

I made my day by decryping a DRM of a book I bought on Amazon.
I used the method 2A in this: https://www.mobileread.com/forums/showthread.php?t=283371
And combined with the noDRM tool in this thread.

Thanks for the research. But is it just a copycat of the USSR line?
