直到指标镜上的刻线恢复到原来的位置（即待测物在铝盘中时的位置），盘中所加砝码的重量就是物体所排开的同体积的水的重量。待测物体的重量与同体积水的重量的比值即为其比重。
Hang glass tay below aluminum tay, and place a glassof wate on the platfom to make glass tay dipped in wate. Place the objectto be measued in aluminum tay and weigh out its weight accoding to the abovemethod. Then move it to the glass tay and immense it in wate completely. Addpoises in aluminum tay until the scale line on index mio estoe to theoiginal position (namely the position that the object to be measued inaluminum tay). The weight of poises in the tay is the weight of the samecubage of wate expelled by the object. The popotion of weights of the objectto be measued and the same cubage of wate is its specific density.

4．测量液体的比重（以对玻盘及中间物无腐蚀作用为限）
装置如前，把一固体作为中间物，如前方法测量出其同体积的待测液体以及水的重量。同体积的待测液体的重量与同体积的水重量的比值，即为该液体的比重。
4. Measue the specific density of liquid (in thelimit of no eoding glass tay and middle object)
The device is the same as the above. Take a solid asthe middle object, and measue out the liquid of the same cubage and the weightof wate accoding to the above method. The popotion of the weights of theliquid of the same cubage and the wate of the same cubage is the specificdensity of the liquid.
5．测量液体的表面张力系数
