On comparing with the common type 4, there are 18 genes presenting change in the rest 21 types, most of them are tRNA genes, and gene replacement, gene increase and gene absence are frequently happened; on the contrary, protein genes are more steady, gene change is mostly of gene replacement. The genome size of Gymnophiona are all smaller than 18000 bps and most of them range from 15000 to 16000 bps, those of Urodela and Anura are bigger than 16000 bps, most of Urodela range from 16000 to 17000 bps, most of Anura range from 17000 to 18000 bps.

For example, to CaSiO〓, wallastonite and cyclowallastonite could be found simultaneously in glazes between the temperature range of 1125℃±10℃, only wallastonite came out below the range, and only cyclowallastonite appeared above the range. Similarly, melilite structure and clinopyroxene structure connected with crystallization temperature. Usually, higher crystallization temperature contributes to forming melilite with simple structure and lower crystallization temperature contributes to clinopyroxene with complex structure.

如钙的偏硅酸盐，硅灰石、环硅灰石的转变温度区域为1125℃±10℃，组分适当的特定釉熔体，高于此温度出现环硅灰石，低于此温度出现硅灰石晶体结构；同样的，黄长石、辉石的出现也与温度有密切的联系，通常，晶体生长的温度较高有利于晶体结构简单的黄长石出现，晶体生长时温度较低有利于稍复杂的辉石结构的出现。

In the Cryptocarya community, the reason for Cryptocarya concinna having high relative frequency and relative abundance is probably not it has wider range of resistance to soil variables but the range of its resistance has much wider spread in broad-leaf forest habitat, or it may just has a wider range of resistance to the limiting factor.
