Fujita is the namesake of the enhanced Fujita Scale which characterizes the intensity of tornadoes.

改进版田级数是以田命名，该级数描述了龙卷风度。

The spell grew geometrically, as it rippled through the air.

咒语中扩散，呈几何级数增长着。

The enhanced Fujita scale rates tornadoes based on how much damage they cause.

增田级数按照龙卷风造成伤害规模分级。

Anything above 200 miles per hour is considered an EF-5 tornado.

只要超过每小时200英里速度都会被认为是田级数5级龙卷风。

So, now, the EF scale, Enhanced Fujita Scale, starts at 0 and goes only to 5.

现, EF级, 增田级数，从0级开始, 只到5级。

He's proposed reducing the number of income tax brackets from seven to three.

他提议将所得税级数从七个减少到三个。

Beyond that the difficulty of solving them rises in almost geometrical progression.

除此之外，解决它们难度几乎呈几何级数上升。

Its wind speeds were greater than 200 miles per hour making it an EF-5 tornado, the strongest classification on the Enhanced Fujita Scale.

龙卷风风速每小时超过200英里，为EF-5型龙卷风，是改良田级数最高度。

So now the EF scale Enhanced Fujita Scale starts at zero and goes only to five and everything above 200 miles per hour is considered a EF5 tornado.

所以现EF级别改良田级数从0开始，只有5级，每小时200英里以上都被认为是 EF5级龙卷风。

So now the EF scale, Enhanced Fujita scale, starts at zero, goes only to five, and anything above 200 miles per hour is considered an EF 5 tornado.

现EF等级，即增田级数，从0开始，只到5级，任何超过200英里每小时风暴都会被认定为EF 5级龙卷风。

We can find out where that point is by writing the infinite series that represents each strategy, setting them equal to each other, and solving for delta.

我们可以通过写出代表每个策略无限级数，将它们设置为彼此相等，并求解 delta 来找出那个点哪里。

Wildeve forgot the loss of the money at the sight of his lost love, whose preciousness in his eyes was increasing in geometrical progression with each new incident that reminded him of their hopeless division.

韦狄一见到他失去爱人，顿时就把输钱一事忘了，每当新发生什么事都让他想起他们之间使人绝望分离，她那份珍贵他眼里，就以几何级数增加。
