diameter factor
1.Seven parameters concerning cellular nuclear sections, including area, perimeter, maximum feret diameter, minimum feret diameter, the equivalent-area circle diameter, circularity factor and shape factor,in adenomatoid hyperplasia of the liver (AHL), normal liver cells (NLC) and hepatocellular carcinoma (HCC), were first measured and analyzed quantitatively using the digital image analysis technology.
2.Seven cellular parameters in adenomatous hyperplasia of the liver (AHL), compared with normal liver cells (NLC) and hepatocellular carcinoma (HCC), were analyzed quantitatively by measuring the seven parameters of the cell nuclei, the area (AREA), perimeter (PERIM), maximum diameter (DMAX), minimum diameter (DMIN), the equivalent circle diameter (DCIRCLE), circularity shape factor (FCIRCLE) and shape factor (FSHAPE) using computerized image analyzer.
3.Two membranes were characterized by methods such as XRD, SEM, BET and so on. A new method was proposed to measure pore diameter and porosity-tortuosity factor, and the pore diameters of two membranes (7.7319μm, 6.1976μm) and the porosity-tortuosity factors (0.07264, 0.06263) were measured and verified.
8.Using full vector finite element method(FEM) with hybrid nodal/edge elements with triangular shape,the relationship between the properties of PCF such as nonlinearity,dispersion slope and zero-dispersion wavelength and of PCF structure parameters of PCF such as the diameter of the air holes,the hole pitch and the air filling factor is investigated.
9.ABVI model intelligent digital type automatical bearing vibration (velocity)tester is suitable for vibration test and selection of ball bearings from bearing bore diameter 10mm to outside diameter 62 mm. It can automatically sort two or four vibration classes according to preset vibration permissible value and peak factor value, and carry on doublefaced vibration measuring of bearing.
10.We designed two kinds of diameter S-shaped curved arteries finite element numerical simulation geometric models in order to study the influence caused by the singular curved factor (such as the curvature radius, the Dean number) to flow , and extract the characteristic flow form related to the curve.
