Critical point data for these dilute SCF-cosolvent binary and ternary systems are imperative for the design of efficient supercritical separation and reaction processes. So that, it is very important to study the critical point data in binary and ternary systems.

这些超临界流体—共溶剂体系的临界点数据对于超临界萃取和反应来说是非常重要的理论参数，因此研究这些二元和三元体系的临界点数据是非常有意义的。

The result showed that the miscibility of the resins played an main role in determining the delamination rate.

最后对共溶剂法测定相容性时的分层速率进行了研究。

From an economic point of view, a solvent having a small minimum solvent flow is a better entrainer and should result in a lower cost design than a solvent having a large minimum solvent flow.

从经济的角度看，最小溶剂流量较小的溶剂比最小溶剂流量较大的溶剂成本低廉，是优良共溶剂。

Therefore, operating the separation sequence at feed ratio optimum requires less entrainer when we use N,N-dimethylformamide.

因此，当我们使用N，N-二甲基甲酰胺作为共溶剂时，在最佳混配比下进行分离操作需要共溶剂的量较少。

As can be seen in Fig. 5, dipropyl ether will be recovered in the distillate using 1-pentanol, N,N-dimethylformamide and 2-ethoxyethanol as entrainers and butyl propionate is the only entrainer studied that inverts the volatility of the azeotropic mixture.

从图 5可以看出，使用1-戊醇、N，N-二甲基甲酰胺和2-乙氧基乙醇作为共溶剂时二丙醚将在馏分中回收，丙酸丁酯是唯一与共沸混合物挥发性相反的共溶剂。

The optimum conditions were starfruit weight (30 g), flow rate (9 NL/min), extraction time (45min), extraction pressure (4500 psi), extraction temperature (65℃), addition volume of ethanol cosolvent (40 ml), ethanol concentration (80%) and static supercritical extraction.

实验结果发现，本次实验最佳条件为杨桃量30 g、杨桃颗粒大小为中颗粒、泄压流速9 NL/min、萃取时间45 min、萃取压力4500 psi、萃取温度65℃、共溶剂乙醇的添加量40 ml 、共溶剂乙醇浓度80 %及萃取方式 SFE-静态，所萃取出之多酚含量1.302 mg/ml 大於非超临界萃取而相同萃取条件下之多酚量0.979 mg/ml。

In this study, the critical point data of ternary systems which is composed of supercritical carbon dioxide, trisodium salt of tri-(m-sulfonphenyl)phosphine and cosolvent were measured the first time. With the increase of mol% of the cosolvent, critical temperature of ternary system increased, and the experimental data show a linear dependence of critical temperature with mol% of the ternary system over the concentration ranges studied too.

北京化工大学硕士研究生论文本文还首次测试了在超临界CO：中加入三磺化三苯基麟以及共溶剂组成的三元体系的临界点数据，发现三元体系中临界温度也随共溶剂的浓度增加逐渐增加，呈一种线性关系。

A study on thermal denaturation of hen egg-white lysozyme was carried out by differential scanning calorimetry and modulated temperature differential scanning calorimetry. It was found that DSC profiles of HEWL were dependent on heating rates and concentrations of enzyme as well as cosolvent.

利用差示扫描量热和温度调制差示扫描量热研究了鸡蛋白溶菌酶在纯水及二甲基亚砜/水混合溶剂中的热变性过程，探讨了酶的浓度、扫描速率和共溶剂的含量对热变性行为的影响规律。

Polystyrene/poly was studied after the thin films were prepared on a glass substrate by spin-coating from tetrahydrofuran and methyl ethyl ketone respectively.

采用原子力显微镜观测了由四氢呋喃和2-丁酮分别作为共溶剂制备得到的聚苯乙烯／聚甲基丙烯酸甲酯共混物薄膜的表面形貌。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
