Bell approaches the issue of rural income from another perspective: she looks at the silk industry in Wuxi, an area in the Lower Yangzi region that developed into a major sericultural and silk-reeling center in the nineteenth century after the Taiping Rebellion.

Bell 通过另一角度研究农村收入问题：她研究了无锡——在19世纪太平天国运动后发展成为主要的养蚕和缫丝中心——的丝绸产业。

ResultThe results of laboratory identification and rural productive test in Jiangsu Province show that it has excellent feeding habit, strong stress resistance, high yield, excellent silk quality and excellent fecundity. The new silkworm variety "Yesanyuan" had been approved by Silkworm Variety Evaluation Commission of Jiangsu Province in 2008, it is suitable to rear in Yangtze River catchment for Spring and Autumn, North sericultural area for all-year.

结果］经江苏省家蚕新品种实验室鉴定和农村生产试验表明，具有食性优、抗逆性强、产量高、茧丝质优良、繁育性能优的特点，并定名为&野三元&。2008年通过江苏省家蚕品种审定，适宜长江流域春、秋季及北方蚕区全年饲养。

地蚕； 预试验；化学成分

Objectv To study the chemical of Stachys geobombycis by priliminary test Methods some researches were made of the extracted mixture for Stachys geobombycis from acidic ethanol,purified water and methanol by using the law of test tube and round filter paper.

目的 通过预试验，初步了解地蚕的化学成分。

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。
