查询词典 critical temperature

The microcrystalline strengthening effect is obvious, due to the sample with fine grain size that was wintered at low temperature and owned good bending strength. At the same time, also due to fine grain sizes, only less tetragonal zirconia grain that their sizes exceeded critical phase transformation size and could change into monoclinal phase when suffering stress, indistinct effect of transformation toughening operated, hence lower fracture toughness was obtained.

由于其晶粒尺寸较小，细晶强化的效果非常明显，因此，材料具有较高的抗弯强度；同时，由于晶粒小，只有一部分晶粒可以达到临界相变尺寸，相变增韧的效果不明显，因此试样的断裂韧性较低。

The experimental results show that hydrophobic association increases obviously with increasing polymer concentration, hydrophobe content, hydrophobic side chain length and temperature. The Critical aggregate concentration of P(AM/NaAA/C_8AM) with different hydrophobic content is 1.5-3g/L. Strong ass...

结果表明，随聚合物浓度、疏水单体摩尔分数、疏水侧链长和温度的增加，疏水缔合作用增强；不同疏水单体含量的P(AM/NaAA/C8AM)的临界缔合浓度为1.5~3.0 g/L；表面活性剂十二烷基硫酸钠与P(AM/NaAA/C8AM)发生了强烈的疏水相互作用，形成混合胶束，得到SDS的临界胶束浓度为8×10-3 mol/L；由于聚合物链上羧基的存在，使其具有良好的 pH敏感性，随 pH值的增大，P(AM/NaAA/C8AM)的疏水缔合作用呈现先减弱后恒定再增强的变化。

The experimental results show that hydrophobic association increases obviously with increasing polymer concentration, hydrophobe content, hydrophobic side chain length and temperature. The Critical aggregate concentration of P (AM/NaAA/C8AM) with different hydrophobic content is 1.5~3g/L. Strong association between surfactant sodium dodecyl sulfate and P (AM/NaAA/C8AM) occurs through the formation of mixed micelles. The CMC of SDS is 8×10^(-3)mol/L. Moreover, because of the presence of-COOH group, the terpolymers have pH-responsive characterization. The hydrophobical association changes greatly with increasing pH.

结果表明，随聚合物浓度、疏水单体摩尔分数、疏水侧链长和温度的增加，疏水缔合作用增强；不同疏水单体含量的P(AM/NaAA/C8AM)的临界缔合浓度为1.5~3.0g/L；表面活性剂十二烷基硫酸钠与P(AM/NaAA/C8AM)发生了强烈的疏水相互作用，形成混合胶束，得到SDS的临界胶束浓度为8×l0^(-3)mol/L；由于聚合物链上羟基的存在，使其具有良好的pH敏感性，随pH值的增大，P(AM/NaAA/C8AM)的疏水缔合作用呈现先减弱后恒定再增强的变化。

It was found that the nucleation temperature is one of the critical factors to influence the polarity of the epi-layer.

在Ill／V比确定的前提下，通过改变缓冲层的生长温度成功获得了两种极性的＊aN外延层样品： 6。

This product adopts the ultra-low temperature critical extraction technology and fragment repairing technology, stimulate the slow release of ossein and ceramide and other active ingredients in the skin, promote the absorption rate and moisture content of the skin around eyes.

本品采用超低温临界萃取技术和片断修复技术，通过特殊的棉绒载体，促使骨胶原、神经酰胺等活性成份在肌肤内缓缓释放，提高眼周肌肤吸收率及含水量。

The results show that the reacting temperature is a key factor to determine the critical oxygen partial pressure.

结果表明，温度是决定临界氧分压P O2的关键因素，随着温度的升高，临界氧分压增加。

The pharmaceutical properties of DSP gel,such as lower critical solution temperature,DSP stability and release in vitro,were esti- mated.The pharmacokineties of DSP-loaded gel and solution were studied after an intratympanic or intravenous administration by determining the concentration of Dex in perilymph.

建立DSP和地塞米松HPLC测定方法；考察凝胶中药物的稳定性；采用扩散池方法评价其体外释放行为；与溶液剂相比较，研究鼓室注射载药原位凝胶后耳蜗外淋巴液中药动学规律。

Photoperiod and temperature play critical roles in controlling flowering time.

光周期和温度在植物开花时间控制中起主要作用。

It is found that the porous medium acting as a heat recuperator can considerably preheat the fuel-air mixture, which promotes the ignition and combustion in the cylinder. And the initial PM temperature is a critical factor controlling the compression ignition of the mixture.

结果表明：多孔介质对混合气具有预热作用可强化发动机的点火燃烧，多孔介质的初始温度是决定压燃点火的决定性因素。

A uniform fast calculation model for R22 thermodynamic and transport properties on Saturation curve, covering temperature from the three-phase point (115.8K) to the critical point (369.3K), is rendered.

在马丁侯系列方程的基础上提出R22在饱和线上热物理性质统一的显式计算模型，并且达到已知饱和线上13个热物理参数（温度，压力，比体积，密度，焓，熵，定压比热容，定容比热容，动力粘度，运动粘度，热导，音速，表面张力）的任意一个，即可求得其它所有参数。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
