Special solutions for the ring circular domain with crack surfaces acted on uniform compressive force, linear compressive force and linear shearing force are deduced in polar coordinate employed the eigenfunction expansion technique in the Hamiltonian system of elastic mechanics. Combined with the general solution for the above problems, the analytical solutions for crack tip fields with surfaces acted on the above three kinds of loads are obtained. These solutions offer theoretical basis to construct analytical elements for plastic analysis of crack.

Six days after inoculation, the cucumber root tip was slightly swollen and symmetrical root-knots were observed at the meristematic and elongation zones. Giant cells were differentiated by previous cambium cells in the center of the root; 10days after inoculation, symmetrical and secondary root-knots were observed at the root hair and upper zones. Vessels were separated by giant cells, around which protoxylem vessels were observed; l6days after inoculation, hypo-vascular tissue appeared earlier than normal; 20-30 days after inoculation, the vertical arrangement of vessels was disordered, shape was distorted and a new vascular tissue appeared in the cortex.
