Medium with higher concentration sucrose can promote bulblet enlargement but inhibit bulblet formation. The best matrix for the highest surviving rate and best growth situation was pearlite/soil (3:1). The number of bulb scales surviving and regenerating decreased significantly as the increasing of days after the treatment of high temperature 37oC. The regeneration rate can be about 40% for 20days. The effectiveness of eliminating LSV with the method got to more than 95% which was significantly higher compared with the control.

蛭石：土、珍珠岩以及珍珠岩：土作为基质时，均能达到较高的成活率和株高，但在珍珠岩：土为3：1作为基质移栽组培球，其成活率和生长状况最佳。37℃热处理随着处理天数的增加，处理后培养鳞片的成活率和子球再生率显著下降，但处理20天子球再生率只能达40%左右，但LSV检出率明显低于未处理的种球，脱毒率达95%以上。

The content of pearlite in alloy exceeded 95% and the content of cementite was under 5%.

该铸铁的珠光体含量大于95%，渗碳体小于5%，抗拉强度可达700~850MPa，硬度为280~350HB，延伸率为3%~5%。

A little of RE can refine the grain size of the austenite, decrease the laminae pearlite cementite.

少量的固溶稀土可以细化BNbRE重轨钢的奥氏体晶粒和珠光体片层结构。

The cementite in the pearlite by ECAP has a stronger ability of spheroidization at a lower annealing temperature.

经ECAP变形的珠光体组织在较低温度退火时，渗碳体具有较强的球化能力。

It is generally considered that the simple mechanical mixture of ferrite and cementite is gained in the pearlite transformation and there is prevenient phase in this process.

一般认为，珠光体转变得到铁素体和渗碳体的机械混合物，而且存在领先相。

After the vanadium content in PD3 steel was more than 0.33%, vanadium carbides would precipitate a lot, and make the lamellar gap sizes of pearlite abnormally coarsen, it was beneficial to toughness of material.

当PD3钢中钒含量增加到0.33%时，碳化钒将大量析出，并使珠光体片间距反常粗化，对韧性不利。

For example, the TTT diagram for a 0.8% C steel is a continuous curve although there is both a pearlite and bainite reaction occurring, but it is difficult to disentangle the reactions sufficiently to study their kinetics.

例如，TTT图中，0.8 ％的碳钢是一个连续的曲线虽然是珠光体和贝氏体反应都发生，但是难以将这两个反应分开而充分研究其各自的动力学。
