查询词典 phase transition

This may involve the transition from one phase to another, or the apace or disappearance of a phase.

这可能涉及到从一个相到另一相的相变，或一个相的迅速生成或消失。

Hydrocyanic acid and water proceed via a five-centred transition states then transformed by its exterior hydrogen-bond; The results show that the activation energy of the isomerizing reaction in the aqueous phase is lower than that in the gas phase. It is likely that the hydrogen bonds formed in the complexes and the solvent effect play an important role.

计算结果表明，在水相中异构化过程的活化能比在气相中低，无论在气相还是在水相中异氢氰酸通过水氢键转化成氢氰酸容易些，而氢氰酸由水氢键转化成异氢氰酸相对要困难些，分子间氢键和溶剂化效应在异构化反应过程中起到重要的作用。

With increasing of heat treatment temperature,the fraction of ω phase decreases and a phase precipitates,which cause the hardness and elastic modulus decrease.When annealing temperature is close to β transition point,the hardness and elastic modulus presents minimum values.

结果表明，当合金中存在ω相时，合金的的硬度和弹性模量最高，随着热处理温度的提高，合金中的ω相消失，代之而来的是a相，而且越接近β转变温度，a相含量越少，对应的弹性模量和硬度越来越低。

The birefringence and viscosity are maximized near the transition from lower phase to middle phase microemulsion condition.

双折射和粘度在接近微乳液从低相位条件过渡到中间相位条件时达到最大。

In the Enterprise Unified Process the Transition phase is followed by a Production phase.

在企业统一过程的过渡期之后的是生产阶段。

The intention of this script is to define the transition from Construction Phase to Production Phase in a project.

本文件的目的旨在定义一个项目从施工阶段向生产阶段的过渡。

Q. Somewhere you have said that current phase is a transition phase.

问：您曾经说过当前阶段是一个过渡阶段。

The synthesized PCU was then characterized by infrared spectroscopy, differential scanning calorimetry, thermogravimetric analysis, small-angle X-ray scattering, and tensile strength measurement. The IR showed that the polymer synthesized by the above two methods both have the polycarbonate-urethane structure and the tensile measurement showed good mechanical performance of the polymer. The DSC and TGA data showed that there is an obvious soft-hard glass transition area, which indicated the existence of the micro-phase separation structure. The extent of the phase separation was affected by the ratio of starting materials, the molecular weight of PCD, and the polymerization method. The decomposition upon heating was observed in two steps. SAXS result showed that the radius (r_2), the distance between domains (d_2), and gyral radius (R_2) of hard segment micro-domain were fairly affected by the starting materials ratio and soft segment content.

IR结果表明两种方法合成的聚合产物均具有聚碳酸酯聚氨酯的结构；拉伸实验表明聚合产物具有良好的力学性能；DSC、TG结果表明，聚合物呈现出较为明显的软硬段玻璃化转变区，表明存在微相分离的结构，相分离的程度受原料配比、软段分子量、聚合方法的影响，其热分解分为明显的两个阶段； SAXS结果表明，聚合物原料配比、软段含量的变化对硬段微区回旋半径R_2，微区间距d_2，微区半径r_2影响不大其值分别为9.5(A|°、29、7.4，但对软段的微区半径及间距影响较大，随着软段含量的增大，软段微区的半径r1和间距d1都增大。

Materials Methods: Beast ultrasound was performedduring luteal phase and late follicular phase in 50 women, aged 25～45, with normalmenstrual cycle and no distinct breast disease; Serum estradiol and progesteronelevel were measured by enzyme immunoassay on the day of ultrasound performed. Onehundred of twenty nine menopause transition women and 318 menopause women wereselected. All of them had ultrasound of breast and serum estradiol report. Breast pain wererecorded. Sixty menopausal women aged 56.8 yr. and menopausal aged 8.2 yr. participated1-year double-blind, randomized, placebo-controlled and 2mg 17β-estradiol continuouscombined with 1mg norethindrone acetate clinical study. Mastalgia was diaried. Breaststructure changes tested by high-resolution ultrasound at the 0 and 12 M.

资料和方法：征集身体健康，没有明显乳腺疾病的正常月经妇女53名，分别在月经的晚卵泡期和黄体期进行超声检查和测血清雌二醇和孕酮水平；收集有HRT前乳腺超声检查和血清雌二醇水平结果的绝经过渡期妇女129名和绝经后妇女318名，记录既往乳腺胀疼、过渡期乳腺胀疼、绝经后乳腺胀疼和既往乳腺病史。17 β-雌二醇2mg加醋酸炔诺酮1mg连续联合治疗和安慰剂随机双盲平行对照临床研究1年的60名参加者，分别在用药前后各进行一次乳腺超声检查，乳腺症状按同一表格由病人日记及经培训的一名医生定期随诊记录乳腺胀疼出现、消失的日期及持续的天数；超声检查用同一方法测量乳腺腺体层厚度、导管宽度、乳腺腺体结构及血流。

The analysis of decomposition mechanisms of the catalyst surface revealed that one of the mechanisms is that activated gas phase O2 captures the hydrogen of the organic pollutants to produce free radicals, which then initiate the catalytic reaction, and produce CO2 and H2O ultimately; and the other mechanism is that the activated organic compounds attack the crystal lattice oxygen, which reduces the valances of the transition metals, then the oxidant of the oxygen oxidizes the transition metals to high valances, which realize the self oxidation-reduction of the catalyst.

催化剂表面有机物降解的机理分析表明，一种反应机理为气相中的O2活化后直接夺取有机污染物的氢，产生自由基，并引发催化反应，最终生成CO2和H2O；另一种反应机理为活化后的有机物直接进攻催化剂的晶格氧，并且使得过渡金属由高价态变为低价态，反应气中的O2再将低价态的金属氧化为高价态，实现催化剂自身的氧化还原循环。
