Furthermore, the results of the antibiotics sensitivity test of 38 isolates to 24 kinds antibiotics show that all isolates have presented antibiotic resistance disparately as well as multi-resistance. All isolates are sensitive to Cephalosporins antibiotics and Aminoglycosides antibiotics such as Amikacin, Cefazolin, Cefradine, Cefoperazone, and Ceftriaxone. Thirty-eight isolates are extremely resistant to Penicillins antibiotics, Lincomycins antibiotics, Tetracyclines antibiotics and Macrolides antibiotics such as Midecamycine, Lincomycin, Carbenicillin, Tetracycline, Amoxicillin and so on. Antibiotics sensitivity test provides guidance for antibiotic application and scientific foundation from poultry farms.

The dispersoid distribution of the second phase could strengthen the surface of the alloy, which decreased the quantity of abrasive particles. The wear volume of the alloy was decreased. The hardness and strength of the alloy were increased after ECAE. The resistance of deformation was improved and the depth and width of furrows were decreased due to the increase of hardness and strength. As a result, the wear-resistance and tribological properties of the alloy were improved after ECAE.

ECAE热挤压处理显著细化了铝青铜合金的微观组织，弥散分布的第二相对合金起到强化作用，减少了剥落磨粒的数量，降低了合金的磨损量；ECAE热挤压处理的铝青铜合金组织细小，强度和硬度高，提高了合金抵抗塑性变形能力，减轻了磨粒对合金表面的犁削作用，提高了合金的摩擦磨损性能。

The pressure drop of the compound tray can be regarded as consisting of dry plate pressure drop, clear liquid resistance, liquid surface tension resistance, and packing pressure drop. The model that has established can fairly predict the pressure drop of the compound tray, the value calculated by the model compared with that detected by experiment is less than 20%.

复合塔板的压降可认为由干板压降、清液层阻力、填料层压降和克服液体表面张力的压降四部分组成，所建立的压降计算模型，能较好地预测复合塔板的压降，计算值与实验值误差在±20％以内，可用于工程设计。

The behavior of resistance of the most common Italian durum and bread wheat (80 and 73 cultivars, respectively) to wheat powdery mildew (Blumeria graminis f. sp. tritici) tested in the fields from 1992 to 1996, was reported. The experiments of adult resistance of these cultivars were conducted annually in about 13 different cereal growing areas.
