A new type all-glass osmometer of very simple construction using asintered glass cylinder as rigid support for de-nitrated collodion membrane isdescribed. The solvent is put inside the osmotic cell and the solution outside.Not more than 10 ml of solution is needed for a determination, while theamount of solvent used is extremely small. No special technique is requiredfor the manipulation of the osmometer. It is especially suited for theosmometric studies with mixed solvents, for very viscous solutions and formeasurements at several temperatures. A polymethylmethacrylate fraction (M_n=6.3×10~5) was dissolved invarious mixtures of toluene-ethanol for osmometric and viscometric studies.Osmotic pressure data show that the value of A_2 goes through a maximum atthe volume fraction of ethanol γ= 0.17, and γ(A_2= 0) = 0.67 estimated fromthe initial slopes of the л/C vs C plots which are appreciably curved. The values of intrinsic viscosity also show a maximum at γ= 0.17, and inthe whole range of the mixed solvents the values of [η] and A_2 are symbatic.The solution viscosity shows slight shear rate dependence, and the deviationfrom Newtonian flow is greatest arround γ= 0.17 and becomes very smallnear the precipitation point, which occurs at γ(c= 1.10~(-3)g/cm~3)= 0.68_2. The experimental results indicate that the polymer coil is most expandedat γ= 0.17, where A_2 and [η] values are at their maximum and the solutionviscosity shows greatest shear rate dependence. This seems reasonable as thecohesion energy density of polymethylmethacrylate (12.2) lies between those oftoluene (8.94) and ethanol (12.80).

作者等使用一种全部由玻璃制成的管形渗透计,半透膜用硝化纤维素溶液涂在熔结玻璃筒的外面,经脱硝基处理后使用。玻璃筒内置溶剂,筒外置溶液。这种渗透计构造简单,操作简便,特别适合于对混合溶剂、粘度大的溶液和在几个温度下的渗透压测量。聚甲基丙烯酸甲酯一个级份(M_n=6.3×10~5)在甲苯-乙醇溶液里的渗透压和粘度数据(25°)指示γ=0.17(沉淀剂的体积分数)时A_2和[η]都呈现最大值。各溶液的粘度都微有切变速度依赖性,与牛顿流动的偏差亦在γ=0.17附近最大。在C=1×10~(-3)克/厘米~3时的沉淀点γ=0.68_2。

The R & D works of all-glass concentric tubular vacuum collectors are presented Borosilicate glass is being used. Calculations showed that the heat loss due to conduction and convection might be ignored when the pressure is lower than 5×10-5 Torr. An appropriate outgassing process has been developed. The water temperature in the tube has been kept at 95× for 6000 hrs while the pressure in the vacuum jacket was lower than 5×10-5 Torr, it may be considered that the collector tube has long vacuum life time.The selective coating being used is double layered black nickel electroplated onto the glass tube which has been chemically deposited with a copper layer in advance. This economical coating withstands the high temperature during outgassing process, and good optical properties (as = 0.89 -0.91, εn = 0.12 -0.15) have been obtained. Microscopic analysis indicated that the electrodeposited coating is amorphous piled small spheres with appropraite size, which improved the absorptance to solar energy.The collector panels consist of 20 tubes, with a white diffuse reflector. The thermalperformance equation is as follows:η =0.53- 1.7ti-ta/I The time constant and the incident angle modifier tests and all-day efficiency have been conducted.

本文介绍了全玻璃同心圆管真空集热器的研制工作。采用透光率高、耐热急变性好的高硼硅玻璃做圆管。计算了气体热传导系数与真空度的关系,当压强为5×10~(-5)托时,气体的热传导为大气压下的0.1%,基本上消除了气体的对流与传导热损。选用了合理的排气工艺,并在管内使用了吸气剂。集热管内水温保持在95℃,经6000小时后真空套管中压强仍低于5×10~(-5)托,表明本集热管有长的真空寿命。 在玻璃表面上化学沉铜,再电镀双层黑镍选择性涂层,该涂层能耐受排气时的高温,光-热性能良好(α_s=0.89—0.91,ε_n=0.12—0.15)。微观分析表明,涂层由适宜尺寸的球形浮雕构成,它是一种无定形物质。采用这种选择性涂层制成的全玻璃真空集热管,成本较低,利于推广使用。 由20支全玻璃真空集热管经铜接头串联成一个单元集热器,背后为白色漫反射板。接头外有聚氨酯保温套。文中给出了集热器的单元流动阻力、冷冻试验结果、集热器的瞬时热效率方程(η=0.53-1.7(t_1-t_0)/I)、时间常数、入射角修正系数和日效率的测试结果。
