The thickness of aqueous diffusion layer d(subscript a and diffusion coefficient (d0) of Hg through SLM were evaluated by the linear slope method, and they were found to be 1.57×10^(-5) m and 7.26×10^(-13) m^2/s, respectively.

Hg在N503-煤油支撑液膜体系中的扩散层厚度δa为1.57×10^(-5)m，膜内扩散系数d0为7.26×10^(-13)平方公尺/s，确立了Hg的渗透系数P方程。

He remembers from his school days that the area of a circle is proportional to the square of its radius, and expects that in the case of a uniform distribution, the number of stations counted should increase like the sequence of number 1, 4, 9, 16, and so on.

他记得他学生年代的时候，一个圆形区域的面积和它的半径的平方是成比例的，所以他认为在均匀分布的情况下，汽油站的数目应该以1，4，9，16等等这种数列增加。

AI:The area of a circle is pi times the radius squared.

這貨它嗎的居然說：圆的面积皮倍，半径的平方。

The formula above requires squaring the difference between the two points, but since we are using fixed point arithmetic, we found that squaring the difference produced too large of a number causing our variables to overflow.

该公式需要平方以上两点之间的差异，但由于我们使用的是固定点算法，我们发现平方差产生太多的变数造成的溢出数量大。

The sequence 1, 4, 9, 16,… lists all positive square numbers in ascending order.
