一种杆菌的

One group includes Bordetella bronchiseptica, B.pertussis and B.parapertussis, and other four species including B.avium belong to another group. They are members of gram-negative aerobic rods and cocci section of uncertain affiliation, Bordetella genus. With the development of rabbitry in our country, B.bronchiseptica infection and co-infections with Pasteurella multocida and Staphylococcus et.al are increased notably.

支气管败血波氏杆菌与百日咳波氏杆菌(B.pertussis)、副百日咳波氏杆菌(B.parapertussis)列为一群，将包括禽波氏杆菌在内的其余四种归为另一群，列于革兰氏阴性好氧杆菌和球菌，博德特氏菌属(Bordetella Moreno-Lopez，1952)。

The E. coli, Pasteurella and Salmonella media were used to culture the isolated pathogenic bacteria in vitro. After culturing for some time, the growth of enteric pathogen colony on the 3 kinds of media was most obvious.

分别用大肠杆菌培养基、巴氏杆菌培养基和沙门氏菌培养塞对分离出的病原菌进行体外培养试验，培养一段时间后，来自肠道的病原菌在3种培养基上的菌落生长最明显。

Using plant bivalent expression vector pCAMBIA1300 and pBI121 as basic components, a new binary vector harboring tomato chitinase gene Chi3 and tomato β-1,3-glucanase gene Glu-Ac, was constructed through sequential restriction digests and ligations recombination. The two genes driven by CaMV35s promoter were successfully transferred into watermelon cultivars "ZhongYuYiHao" via Agrobacterium-mediated transformation.

构建了同时含有番茄儿丁质酶基因（Chi3）和β-1，3-葡聚糖酶基因的双价抗真菌基因植物表达载体，以西瓜子叶块为外植体，采用根癌农杆菌介导法，将Chi3和Glu-Ac同时导入西瓜栽培种&中育一号&，共获得46株抗性再生植株。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
