The yolk proteins were collected through the anatomization of the maiden eggs and the eggs in different embryo development stages. The yolk proteins were separated by two-dimensional electrophoresis and followed the image analysis. Over 203 protein spots were found to exist in the yolk protein of silkworm eggs. Some different patterns of yolk protein spots were found in silkworm of various varieties. While, little variation of yolk proteins was detected during different development stages of any silkworm variety.

An adaptive grid scheme controlling cell area is used to generated grids in the divergent section of symmetric annular nozzle, and the generated grids are used in the flowfield calculation through the uncoupled way. The elliptic equations are used to generate grids in three dimensional regions of FDN divergent section, the source terms used in the equations employ a mathematical form which is independent of the boundary shape and of the boundary grid point distribution, the free parameters contained in the source terms are determined by the two restraint conditions, the intersection angle of transverse grid lines with boundaries and the local curvature of the transverse grid lines at the boundaries, and the interior grid distribution controlled directly by the grid point distribution assigned on the boundaries is realized, it makes the grid more clustering near the nozzle wall. For the generated grids in the whole computational regions have a good smoothness and orthogonality, the accuracy of calculation in the flowfield is ensured.
