相转变

The only alternative and referential way to predict the phase transformation temperature is to make use of the continuous cooling transformation diagrams, which are measured dilatometer curves that have not taken the effect of practical welding conditions into account.

由于焊接过程的瞬时性和焊接热影响区温度场、应力场的复杂性，该区域的组织转变往往并不完全遵守热处理条件下CCT 图所反映出的相变规律，因此为了提高焊接接头的性能，有必要深入研究真实焊接条件下热影响区组织的相变规律，尤其是马氏体组织的相变规律，因为在含碳量较高或合金元素较多的情况下，这两类钢的淬透性较强，在焊接热影响区极易形成高硬度马氏体组织，从而严重影响焊接接头的性能。

A schematic model was proposed to illustrate the occurrences of various lithologies and lithofacies associations. The erosional surfaces on siliciclastic mudstones, funnel-shaped structure, and the exhuming of massive cold-seep carbonates exposed might have been occurred concurrently during a tectonic unstable time in SW Taiwan. The deposition of fossiliferous mudstone interfingered with the conglomerate lithofacies, and represented the rapid facies transition from siliciclastic (non-carbonate) into carbonate environment.

The multiphase transport model of heavy ion collision includes parton phase and hadron phase and is suitable for the study of phase transition.

相对论重离子碰撞的多相输运模型AMPT中包含有部分子相和强子相，比较适合于研究两相之间的转变。

Nanoparticle of an appropriate proportion were homogeneously dispersed in the PI matrix, and the interfacial adhesion between the matrix and the nanoparticle was hence strong owing to the high specific surface area and reactivity of the nanoparticle. Subsequently, the molecular chains of PI attained unchanged or even increased interaction at a proper mass fraction of the nanometer particle, which contributed to improve the wear-resistance of the nanocomposites.

采用PI的原位聚合填充方法，利用聚酰亚胺与无机纳米表面较强的相互作用（如静电作用、较强的范德华力、氢键甚至化学键的形成），用非水悬浮工艺制备了无机纳米/聚酰亚胺纳米复合材料，率先用大型分析仪器全面地表征了复合材料的结构，采用原位聚合填充法制备的聚酰亚胺复合材料中，无机纳米分散状态良好；无机纳米氧化物/聚酰亚胺复合材料的结构表征显示出PI有机相和SiO〓无机相之间形成了键联型复合体系，两相相互影响；在复合体系中，单相本体的结晶结构并未发生改变；在摩擦过程中纳米氧化物没有发生价态的转变；无机纳米氧化物的加入，提高了聚酰亚胺的耐热等级；适量纳米氧化物并不影响复合材料的机械性能， 2。

The slight redissolution and then coarseness of primary Si phase at higher annealing temperature had been found,but the coarsening ratio of primary Si phase was lower than that of β-Al4FeSi.

退火温度低于310℃时，δ-Al4FeSi2相未明显粗化；当退火温度高于310℃时，亚稳相δ-Al4FeSi2转变成稳定相β-Al5FeSi，β-Al5FeSi相随退火温度的提高而明显粗化。

The calculated results are consistent with those of phenomenological crystallographic theory.

采用热分析方法研究干馏温度对半焦着火方式影响的实验，结果表明：随着干馏温度的升高，油页岩半焦的着火方式将由均相着火转变为多相着火；干馏温度500℃不仅有利于炼制页岩油，从燃烧角度来说，该温度所制取的半焦着火温度低且着火方式为均相着火，因此也有利于锅炉的燃烧。

It is considered that when temperature begins to fall down under Ms, martensite and the untransformed mother-phase are in a kind of thermobalance. We try to use the equations in marten- site transform to get the mathematical relationship between the dynamics of the microclamp and the temperature, also including some useful results for design and fabrication of the microclamp. We hope these results will form the work principle base for SMA microclamp.
