比重瓶

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.

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，装上温度计，置20°C（或各品种项下规定的温度）的水浴中放置若干分钟，使内容物的温度达到20°C（或各品种项下规定的温度），用滤纸除去溢出侧管的液体立即盖上罩。

The relative densities of flavors were determined by pycnometer and densimeter.

目前测定香精密度的方法主要有标准传统法-比重瓶法和密度仪法。

The temperature of the determination environment of the pycnometer and balance should be a little bit below 20°C or that specified under individual monograph.

用比重瓶测定时的环境（指比重瓶和天平的放置环境）温度应略低于20°C或各品种项下规定的温度。

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。

A standard vessel used in measuring the density or specific gravity of materials.

比重瓶一种标准容器，用于测量物质的密度或比重

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。

In some cased, the Westphal balance is used, for example, in the determination of the relative density of a volatile liquid.

液体药品的相对密度，一般用比重瓶测定；测定易挥发液体的相对密度，可用韦氏比重秤。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
