It is known general knowledge for those skilled in the art, and can be fitted according to being actually needed during measure
When adjustment.
For convenience when in use, Water Tank with Temp.-controlled can be used carrying out constant temperature processing, will when carrying out constant temperature processing
Specific gravity bottle scale part, which immerses, carries out constant temperature processing in the water in Water Tank with Temp.-controlled.And to ensure to read specific gravity bottle scale in first time
Temperature value Xiang Cha≤0.5 DEG C of Water Tank with Temp.-controlled when reading specific gravity bottle number of division with second during number, to ensure that temperature is tied to measure
The influence of fruit.
For the convenience weighed in measure, while and can enough ensures the accurate of measure, and it is saline and alkaline to add specific gravity bottle quantification
The quality of ground soil can use 50g, and its accuracy will be controlled in ± 0.01g, and in order to make bubble discharge so that
Anhydrous kerosene alkaline land soil full penetration, can be by the way of vibration of ultrasonic wave, and to prevent the material in bottle from spilling,
According to situation during actual measure and the selection of specific gravity bottle, appropriate adjustment can be carried out to the taken amount that weighs up of alkaline land soil,
In order to the convenience of measure.
Consider measurement and operational error, described alkaline land soil density value is measured twice, and its value is accurate to
0.02g/cm3, and result of the test Zhi Xiang Cha≤0.05g/cm twice3, take measurement result average value twice.For measurement result
Selection and pendulous frequency determination, can also according to reality measurement situation reasonably be selected, to ensure salt-soda soil
Ground density measurement value it is accurate.
The present invention determines the density of alkaline land soil using anhydrous kerosene, due to comparing when filling sample using anhydrous kerosene
Easily, the operating time is saved, makes simple to operate, and measurement result is accurate；Can not only be convenient by the detection method
