Plane strain, mode I quasi-static steady state crack growth is investigated utilizing the finite element method. It is once again established that TNT plasticity can significantly increase the stress level near the crack tip. The crack tip stress singularity is higher than or equal to the square-root singularity of elastic K field and is also independent of the plastic hardening exponent.

Additionally, the TW I attenuated vaccine strain had no reversion to virulence after five back passages in chicks. Therefore, these two IBV strains were transferred to a manufacturer for the vaccine production and evaluation. The safety and the efficacy of this attenuated strain were also tested in SPF chickens.

In this paper, the effect of tensile strain on the transport characteristics of YBCO coated conductor has been investigated at I, n value and self field and 77K. It is observed that the I versus strain curve can be divided into three regions. The increase of I in the beginning can be attributed to the residual compressive stress and the degradation of I thereafter is the result of the decreases of both the pinning potentials in the weak-link area and inter-grain critical current density. Meanwhile n value showing little variation in the testing range indicates that the plastic deformation has little influence on the longitudinal I distribution.
本文通过实验研究了拉伸应变对YBCO涂层导体的临界电流I(下标 c、n值和交流损耗的影响（零场，77K），实验结果表明，随着拉伸应变的增大，YBCO涂层导体I(下标 c的变化分为三个阶段，开始缓慢上升，然后缓慢下降，最后快速下降，I(下标 c的上升表明带材中存在残余压缩应变，I(下标 c的衰减是由于应变导致弱连接区域的钉扎势与晶界间临界电流密度同时减小引起的；而n值随应变增加基本上没有变化，说明沿导体长度方向的I(下标 c分布没有变化。
Using a long-term reared housefly population which is very susceptible to pyrethroid insecticides as the susceptible strain, a population collected in 1993 in Shanghai and has been treaded by cyhalothrin as the resistant strain, we bioassayed their susceptibility to organophosphorus, carbamate, pyrethroid and organehloride insecticides. We also investigated the role of metabolic enzymes, i. e. esterase, GST, MFO and of target enzymes, i. e. AChE and 〓-ATPase in resistance to insecticides. Cyhalothrin resistance inheritance, the co-toxicity coefficient of cyhalothrin and methylene dithiocyanate was also studied. The insecticides resistance in adults and larvae of houseflies was compared and the mechanism of resistance differences between adults and larvae was discussed.
