相转变

The nanophase anatase of different size (the average is 40 nm) was synthesized with chemical precipitation method.

采用化学沉淀法制备出 40nm的锐钛矿，并用拉曼光谱对纳米和块体锐钛矿到金红石的相转变过程进行了研究。

V1-x-yWxAuyO2 thin film has a low transition temperature and a narrow bandwidth of hysteresis loop which was applicable to bolometer materials for IR gas sensor.

而薄膜热迟滞回圈也有修正的效果，而 V1-x-yWxAuyO2复合薄同时具有较低的相转变温度及较狭窄的迟滞回圈，使本复合薄膜更有利於红外光气体感测器之热敏材料应用。

The phase transition temperature of liquid crystal decreased as the introduction of long chain alkyl group.

药物透过速率亦随温度升高而增大；当温度升高到液晶的相转变温度时，透过速率大幅度增加。

When heated to 1 300 ℃, these metastable phases transformed into stable (3∶2) mullite,α-Al 2O 3 and cristobalite.

在室温 1 30 0℃热震过程中，这些亚稳相转变成稳定的(3∶ 2 )莫来石和α- Al2 O3，同时也有少量的方石英析出。

The phase shift is determined by requiring that the optimised lie close to a minimum in the dihedral potential.

相转变取决于二面角势能的最小化需求。

In order to produce dry sanding paper applied to soft materials, the slurry coating was prepared by smearing unblocked materials according to the phase change principle of endothermal agents.

为研制适用于软质材料磨削的干磨砂纸，通过涂覆特殊的防堵塞材料，利用吸热剂的相转变原理，研制了干磨砂纸超涂层浆料。

Methods Gelators of N-lauroyl-l-alanine methyl esterand N-lauroyl-l-alanine ethyl esterwere synthesized with l-alanine methyl ester,l-alanine ethyl ester and lauroyl chloride as materials.

方法以l-丙氨酸甲酯盐酸盐、l-丙氨酸乙酯盐酸盐和月桂酰氯为原料，合成月桂酰-丙氨酸甲酯凝胶因子及月桂酰-丙氨酸乙酯凝胶因子，采用IR、1H-NMR、MS对其结构进行表征，并对其熔点、热稳定性、在各种植物油中的最小胶凝质量浓度、相转变温度等基本性质进行了研究。

These phenomena occurred due to the increased free volume and chain mobility of polymers, and the decreased energy barrier for crystal form transition by the plasticization effect of scCO2 and other supercritical fluids.

这些现象的发生，是由于超临界二氧化碳及其它超临界流体增大了聚合物的自由体积和链活动性，降低了相转变的能垒。

Pure iron specimens were implanted by nitrogen ions with a fluence of 7×1017 ions/cm2 using ion beam implantation at an extracted voltage of 40kV.Composition and valence studies were carried out by X-ray photoemission spectroscopy;Glancing angle X-ray diffraction was employed to examine the phase transformation.

采用40kV的氮等离子体离子注入工业纯铁，注入剂量为7×1017ions/cm2，X射线光电子能谱研究表面注入层元素的成分和价态，X射线衍射分析注入层的物相转变，采用恒电位极化腐蚀试验研究了离子注入后材料在人工模拟体液中腐蚀行为。

We also find two species can coexist only when taking the medium values in some range of parameter,if it is too large or too small only one population can exist or none of them can .

其它的参数不变，而只变化某一个参数的取值，且这一取值变化符合这一参数划分区间，定态会经历这一区间内的多种状态，且会出现临界点，普通渗流与定向渗流类相互转化，且出现两个临界点，两次相转变。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
