Question

求助，帮忙翻译下面这段文字啊，谢谢啦！

The first experiments the relationship between viscosity, pressure-viscosity coefficient and refrigerant concentration has been investigated. Also a method to estimate the pressure-viscosity coefficient of oil/refrigerant mixtures based on the
difference in molecular weight of the refrigerants are shown.

Viscosity and pressure-viscosity coefficients for mixtures of polyolester oil and commonly used refrigerants were measured using a modified high-pressure Höppler viscometer, designed by Jonsson and Höglund [9]. The instrument’s accuracy is a
few cP, which allows measurements of oil/refrigerant mixtures at high levels of refrigerant to be made. The viscometer can be pressurised up to 34 MPa, and the pressure-viscosity coefficient of the oil/refrigerant mixtures were calculated according to Barus .

绝对自已查词典翻译，由于是财务专业，所以有些词可能翻译不准，如果有财务英语要翻译，可以找我，我可以翻译得要好一些

关于粘度，粘度比系数和冷冻浓度的实验已展开。由相对分子质量不同而估测油混合物的制冷剂的粘度比系数的方法将展示。
高分子聚烯烃油和常用制冷剂的混合物的粘度和粘度比系数将用一种修正的高压由Jonsson和Höglund设计的Höppler粘度计测量。仪器的精准度有一点cP(不知道是什么专业词汇)，这让高度的制冷剂下的油混合物得已制成。粘度计能承受34兆帕的压强，油混合物制冷剂的粘度比系数根据巴拉斯效应计算。
