According to the existence results of general equilibrium problems and vector equilibrium problems have been studied more and more. Inspired and motivated by these research results, this paper is devoted to study systematically a class of equilibrium problems, which is unify and extension of a large number of known equilibrium problems and variational inequalities problems. The research is carried on from three aspects.Firstly, in finitely continuous topological spaces, we introduce four new types of the system of generalized vector quasi-equilibrium problems, and we derive some existence results of a solution for the system of generalized vector quasi-equilibrium problems via the maximal element theorems in product finitely continuous topological spaces.Secondly, in complete metric spaces, we provide the Ekeland variational principle to equilibrium problems with set-valued maps. And via the Ekeland variational principle, existence results for vector equilibrium problem with set-valued maps and the system of vector equilibrium problem with set-valued maps.

On the basis of Raman and FTIR spectra research on melt structure and water solubility mechanism in albite glasses, we can make the following conclusions:(1) Higher pressure (1bar-2. 0GPa) can lead to below frequency region (50-650cm〓) shift to higher frequency and become narrower, and result in high frequency region (850-1300cm〓) move to lower wave number and become narrower at the same time. These are consistent with the decrease of average T-O-T angle and distribution scope of bond angles (0). In addition, the intensity of 580cm〓 band decrease with increase of pressure and the changes are obvious while pressure is in the range of 0.8-1. 0GPa. And these result from the"collapse"of the planar three membered -containing rings within the glass structure.
通过对高温高压下钠长石熔体结构及水在钠长石熔体中溶解机制的Raman和FTIR光谱实验研究,可以得出以下结论:(1)随着压力升高(1bar-2.0GPa)NaAlSi〓O〓熔体玻璃Raman光谱的低频区(50-650cm〓)不断变窄并向高频方向移动,同时高频区(850-1300cm〓)不断变窄且向低频区方向移动,这表明随着压力升高T-O-T键角不断减小,并且分布范围变窄,T-O-T键角这种变化从而可使T-O键的力常数减小,导致键强减弱;另外,580cm〓谱峰强度随着压力升高不断减弱,并在0.8-1.0GPa时最为显著,这是由于在0.8-1.0GPa时包含的平面三元环结构的"垮塌"造成的。

The macroscopic rheological parameters and microstructure parameters were closely related, it is helpful to explain the essence of multiple rheological properties through the analysis of which the wax evolution process and microstructure of the crude oil which is waxy and high viscosity; the yield time of gelled waxy crude oil monotone increases along with the decreasing of rate of shear (the time of stress effect prolonged), there was power function relationship between them, it can be expressed with ; when adding diesel oil to Sudan crude oil, dilute proportion bigger the eccentricity degree of paraffin particles were bigger too, that was to say the symmetry of wax crystal was better, the wax crystal form fabric more hardly when the intermolecular interaction was smaller; in the light of macroscopica, the fall extent of the abnormity temperature, solidifying point and viscosity could be larger along with the accretion of dilute proportion, as a result, it's rheological properties could be improved.
SD原油析蜡点为94℃,析蜡高峰为50~30℃,异常点为40℃;其蜡晶颗粒细小、对称性差,所以具有较大的比表面能,容易形成联生、联锁结构;损耗角曲线与储能模量曲线或损耗模量曲线的交点所对应的温度与原油凝点或倾点温度非常接近,大约在39℃左右;也就是说,含蜡原油粘弹特性曲线的交点可以表征其流动性;原油宏观流变参数与微观结构参数密切相关,原油析蜡过程及蜡晶微观结构分析有助于诠释易凝高粘原油多重流变特性的本质;胶凝含蜡原油的屈服时间随剪切速率的降低而单调增加,二者显然存在幂函数关系,可用关系式描述;当SD原油加柴油稀释处理时,稀释比越高,蜡晶颗粒的偏心度也越大,亦即蜡晶对称性越好,分子间作用力越小,蜡晶颗粒越不易形成结构,宏观表现为异常点、凝点及表观粘度等流变参数下降的幅度越大,流动性越好。
