A total of 197 F2 plants from the cross Chuanmai 42×Yr24/3*Avocet S and 726 F2 plants from Chuanmai 42×Yr26/3*Avocet S showed high resistance to CYR32 without segregations. Seedling testes with 26 PST isolates showed an identical reaction patterns for Chuanmai 42 (YrCH42), Yr24/3*Avocet S (Yr24) and Yr26/3*Avocet S (Yr26). In considering the allelic test of two F2 populations and seedling responses to 26 PST isolates as well as chromosome locations, YrCH42, Yr24 and Yr26 are likely to be the same gene.

Results: The numbers of Bombesin positive pulmonary cells, the lamina propria S-l00 protein, neuron-specific enolase positive nerve fibers, IgE positive cells, mast cells and IgE positive mast cells significantly increased in bronchiectasis. The changes of pulmonary endocrine cells, nerve fibers and IgE positive cells were more significantly in hyperplastic BALT areas. The S-100 and NSE were found in lymphoid tissue and BALT. A close contact was found between mast cells and the S-100 positive nerve fibers. An IgE positive outer zone was found on MC surface. Mast cells and IgE positive cells were seen in the bronchial epithelium and alveolar septa.

Thirdly, a new type base isolation system, i. e., slide-limited friction base isolation system is presented in this paper. Based on this system, harmonic and subharmonic periodic response of S-LF subjected to harmonic motion is investigated by using Floquet theory. Dynamic response of sliding structure subjected to earthquake ground motion is calculated with a precise high order direct integration method, and the numerical results are presented in terms of maximum acceleration response spectra of supcrstructure and maximum sliding displacement response spectrum. By comparison with isolating effects of pure-friction base isolation system and resilient-friction base isolation system , it shows that the isolating characteristic of S-LF is superior to P-F and R-FBI. Through analyzing an engineering example, it is observed that the maximum inter-storey shear force and absolute acceleration of sliding structure to earthquake ground motion are very different from those of traditional structures.

Results indicate that when the strain rate is 1200 s-1, the twin number of samples in different orientation increases with plastic strain increasing; when the strain rate increases to 2800 s-1, the σ-ε curves have no obvious charges as the angle is 0o and 45o, compared with that at 1200 s-1; however the σ-ε curves vary from concave to convex when the angle is 90o, because thermal softening has occurred with increasing plastic strain, which results in the number of twin decreasing, and smaller strain hardening
