Basing on contrastive test ahout the dosage of soil in grain-size analysis by hydrometer and comparingwith other countries relative code, the author thinks that the relative rule in national standard should bemodified in order to make it perfectly.

Relation between dissolving quality and particle density;

We found that there are particles on the fracture faces of peribacteroid membranes,but particle density on P face and E face is different,the former is quite abundant,the latter is less.

Some improvements on particle analysis experiment based on densimeter settlement method

It is particularly suggested that the soil of low plasticity, 10≤Ip≤12, be classified according to the content of clay particles in grain analysis.

A curve fitting and revising methods to solve hydrometer grain analysis is presented, and proved good satisfactory.

Several oil monitoring technologies used widely at present are compared and analyzed in detail,including analysis of normal physicochemical characteristics,spectrum analysis,ferrography analysis,grain analysis,etc.

Measurement of microcapsules using morphological reconstruction by opening based granulometry;

Texture segmentation based on double parameterized granulometry;

Granulometry is analyzed in detail as an example to show this essential connection and we come to the conclusion that the PCNN granulometry algorithm we proposed in this paper is entirely equal to the granulometry algorithm based on mathematical morphology with certain structuring elements.
