查询词典 pycnometer

Fill a clean, dry and accurately weighed pycnometer with the substance being examined (keep the temperature below 20°C or that specified under individual monograph), fix the thermometer (no air bubble is left in the pycnometer). Place the pycnometer in a water bath maintained at 20°C or the specified temperature, allow to stand in the water bath for several minutes, so as to raise the temperature of the content to 20°C or to the temperature specified in the monograph.

Density, surface tension and rheological characteristics are the essential properties of the non-Newtonian fluid. Pycnometer, surface tensiometer, and rheometer were adopted respectively to measure the density, surface tension and rheological characteristics of 0.25%, 0.50%, 0.75% PAM aqueous solutions at 293.15K. The parameters of equations were fitted in terms of the experimental data.

Wipe away the liquid overflown from the side tube with a piece of filter paper and put the cap immediately. Remove the pycnometer from the water bath and clean off any material on the outside with a piece of filter paper, weigh the pycnometer accurately and calculate the weight of its content.

然后将比重瓶自水浴中取出，再用滤纸将比重瓶的外面擦净，精密称定，减去比重瓶的重量，求得供试品的重量后，将供试品倾去，洗净比重瓶，装满新沸过的冷水，再照上法测得同一温度时水的重量，按下式计算，即得。

Some of the liquid spills out through the capillary constantly with the rise of the temperature of the content. Wipe away the overflown liquid with a piece of filter paper at any time until the fluid does not overflow anymore. Remove the pycnometer from the water bath rapidly. Proceed as described under method (1), starting from the words "clean off any material on the outside with a piece of filter paper…".

取洁净、干燥并精密称定重量的比重瓶，装满供试品（温度应低于20°C或各品种项下规定的温度）后，插入中心有毛细孔的瓶塞，用滤纸将从塞孔溢出的液体擦干，置20°C（或各品种项下规定的温度）恒温水浴中，放置若干分钟，随着供试液温度的上升，过多的液体将不断从塞孔溢出，随时用滤纸将瓶塞顶端擦干，待液体不再由塞孔溢出，迅即将比重瓶自水浴中取出，照上述（1）法，自"再用滤纸将比重瓶的外面擦净"起，依法测定，即得。
