每年它要造成非洲高粱60到70亿美元的损失。

Every year it causes six to seven billion dollars in damage to African grain sorghum. Sorghum is important to the local food supply.

每年，有价值六十至七十亿美元的非洲高粱受其破坏，高粱是当地粮食供应的重要来源。

United Nations' agriculture and food aid officials said that record prices of imported food have prompted a substitution effect, boosting the demand – and the price – of indigenous staples such as yam, sweet potato, sorghum, cassava, millet or teff in Africa, Latin America and parts of Asia.

联合国农业和食品援助官员表示，创纪录的进口食品价格引发了替代效应，进而推高了非洲、拉美和亚洲部分国家本土主要粮食作物——如山药、红薯、高粱、木薯、小米或画眉草——的需求和价格。

The seeds can also resist the Striga weed, a big cause of crop failures in Africa.

爱杰塔，数百万的非洲同胞才可以吃到更多的高粱。

Striga is a parasitic weed that Africans commonly call witchweed. The plant attacks sorghum and other crops and steals water and nutrients from the roots.

Striga是一种寄生草，非洲人通常称之为&独脚金&，这种植物从高粱和其他农作物的根部吸收水分和营养，从而破坏庄稼。

The Ethiopian geneticist and seed-breeder, who joined the Purdue University faculty in 1984, is being honored for his work in developing strains of sorghum that are resistant to drought and the parasitic weed Striga, which has been a plague to farmers throughout sub-Saharan Africa.

这位埃塞俄比亚遗传学家和育种家在1984年到普渡大学任教，他这次得到世界粮食奖是因为他培育的高粱品种具有耐旱性并能抵制寄生杂草斯特赖加的衍生，这种杂草是整个非洲撒哈拉以南地区农民面临的大难题。

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。
