In this paper a conception of supply subchain is introduced and based on the analyses of the characteristic of the supply subchain , one simple model is support.

It has ben demonstrated in this paper that if any subst A of Lattice that contains an upper surface could be described as the subchain product of Lattice it must be one of LF - subgroup images;therefore the paper has answered one of the open questions raised by S.

The crystal structure and molecular chain behavior of mechanically micronized corn starch were studied by various methods,such as polarized microscope,X-ray diffraction,DSC method,GPC and LLS.

When epoxy group is introduced into the double bonds of the main molecular chain, the molecular polarity is enhanced,while the high elongation character remains essentially.

Effects of different long-chain molecules on properties of thermally-reversible transparent imaging materials;

DCYQ[6]and CuS_O4 were formed supramolecular chains through hydrogen-bonding.

By using a multiple scales method,we study the lattice vibration of a monoatomic chain taking into account the nearest neighbour and the second next nearest neighbour harmonic and anharmonic interactions.
