目的论视阈下的英译茶叶广告翻译研究

广告翻译在中国产品打入国外市场的过程中起着至关重要的作用。广告作为向公众传达信息的宣传工具,具有极强的目的性及功能性,而目的论翻译的核心就是功能作用,两者的强强联合使产品的宣传作用更加广泛深入。中国茶文化博大精深、源远流长,为向世界更好的宣扬茶文化,就应充分利用广告翻译对其进行广泛宣传。本文从目的论出发,对英译茶叶广告翻译进行了简要研究。     

电缆交接试验中发生绝缘击穿故障的位置查找

1情况简介 山东省龙口市110 kV新嘉变电站新增10 kV府西线,全程为电缆线路,使用YJV交联聚乙烯塑料电缆,全长2 800m.电缆分为三段,中间由两面环网柜连接,为将来新增用户预留接入点,电缆附件全部采用冷缩预制结构电缆终端、中间接头等.电缆附件安装完成后进行绝缘试验,在电压升高到5 000V时,L3相绝缘击穿放电.排除了电缆外部原因导致的放电后,试图重新对电缆加压,但除泄漏电流急剧增加外,试验电压一直在零位左右.

Seroprevalence of and agroecological risk factors for Mycobacterium avium subspecies paratuberculosis and neospora caninum infection among adult beef cattle in cow-calf herds in Alberta, Canada

A province-wide cross-sectional seroprevalence and agroecological risk factor study of Mycobacterium avium subspecies paratuberculosis (MAP) and Neospora caninum (NC) infection among cattle in 100 cow-calf herds in Alberta was conducted. The seroprevalence of MAP in adult cattle was 1.5% across all herds. Using a widely accepted herd test cutpoint of 2 or more seropositive cows out of 30 animals tested, 7.9% of herds were estimated to be infected (95% confidence interval (CI): 2.3-23.4%). Seroprevalence of MAP differed by agroecological region; specifically, cattle and herds in areas with high soil pH (> 7.0), southern latitudes, and arid climates had a moderately reduced risk of infection (P < 0.10). Seroprevalence of NC infection was 9.7% among adult beef cattle province-wide--these levels also varied by agroecological region--with 91.0% of herds infected overall.     

Clinical and in vitro efficacy of amoxicillin against bacteria associated with feline skin wounds and abscesses

A clinical trial involving 122 cats with infected skin wounds or abscesses presented to 10 veterinary clinics was conducted to evaluate the efficacy of 2 oral amoxicillin drug products (a paste and a suspension). A 2nd objective of the study was to identify bacteria involved in such infections and verify their in vitro sensitivity to amoxicillin. Samples of wound exudate were harvested at the time of presentation and submitted for aerobic and anaerobic culture. The sensitivity to amoxicillin of isolates thought to be infecting agents was tested, using a standard minimum inhibitory concentration method. Pasteuralla multocida and obligate anaerobes of the genera Prevotella, Fusobacterium, and Porphyromonas were the most frequently isolated pathogens. Overall, their in vitro susceptibility to amoxicillin was very good. Both drug products were clinically efficacious with a global success rate of 95.1% for cats administered oral amoxicillin at 11-22 mg/kg bodyweight (mean 13.8 mg/kg bodyweight) twice daily for 7 to 10 days.
