Claims (2)

1. Способ определения плотности твердых тел, включающий взвешивание исследуемого тела, помещенного в измерительную кювету, отличающийся тем, что, взвешивание проводят в рабочей жидкости в воздушном пузыре, вначале - при нормальном давлении, затем - при пониженном, после чего очищают кювету от исследуемого тела, заполняют ее рабочей жидкостью и определяют вес кюветы в рабочей жидкости, а расчет плотности исследуемого вещества проводят по известной формуле.1. A method for determining the density of solids, including weighing the test body, placed in a measuring cell, characterized in that the weighing is carried out in a working fluid in an air bubble, first at normal pressure, then at low pressure, and then the cell is cleaned from the test body , fill it with a working fluid and determine the weight of the cuvette in the working fluid, and the density of the test substance is calculated according to the well-known formula. 2. Способ по п.1., отличающийся тем, что формула для расчета плотности имеет вид:2. The method according to claim 1., Characterized in that the formula for calculating the density has the form:
Figure 00000001
,
Figure 00000001
,
где ρж - плотность рабочей жидкости;where ρ W - the density of the working fluid; m - навеска исследуемого вещества;m - sample of the test substance; G1 - вес кюветы с исследуемым веществом в рабочей жидкости при нормальном давлении;G 1 - the weight of the cell with the test substance in the working fluid at normal pressure; G2 - вес кюветы с исследуемым веществом в рабочей жидкости при пониженном давлении;G 2 - the weight of the cell with the test substance in the working fluid under reduced pressure; G3 - вес пустой кюветы в рабочей жидкости;G 3 - weight of the empty cell in the working fluid; Рн - нормальное давление;P n - normal pressure; Рв - пониженное давление.P in - low pressure.
