查询词典 pycnometer

And more, the experimental densities, viscosities and interfacial tension data of MPO+H_2O binary system at 298.15K～367.15K were presented under atmospheric pressure, which Ostwald-Sprengel-type pycnometer used for determination of density, Ubbelohde capillary viscometer for viscosity and Maximum Bubble Method for surface tension.

结果表明：纯液体MPO的密度与温度关系符合Francis模型ρ／g.cm~(-3)=1.032-6.90×10~(-4)t／℃；一定温度下MPO+水二元体系的密度随浓度变化大约在70％处出现了一极大值；纯液体MPO的粘度与温度关系符合Andrade方程1n=-14.526+5854.9／T。

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。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
