But Nb adding increases the under-heating austenite stability, reduces the temperature of phase transformation point and postpones the transformation of pearlite.

而铌元素的加入增大了过冷奥氏体的稳定性，相变点温度降低，并且推迟珠光体的转变。

These transformations are made up of renormalization group. Then the fixed point of transformation can be found, among which those unstable ones are critical points of phase transition.

然后找出重整化变换的不动点，在所有不动点中那些不稳定不动点是发生相变的临界点。
