The heart shape, called a cardioid, is common in nature.

心形，称为心形，在自然界中很常见。

This  largest cardioid section includes the values of c so that the process eventually converges  to some limit.

这最大的心形部分包括 c 的值，过程最终收敛到某极。

Yet again, asking a question where  we tweak a parameter for one of these functions yields this iconic cardioid and bubbles shape.

再次，提问题，我们在哪里调整这些函数之的参数，会产生这种标志性的心形和气泡形状。

And then if that's not enough of a challenge, try using the result that you find to show that  this condition corresponds to the main cardioid shape of the Mandelbrot set.

然后， 如果这还不够具有挑战性，请尝试使用您找到的结果来证明这种情况对应于曼德布洛特组的主要心形形状。
