Using public toilets in China can often be a challenging undertaking, particularly for those not practiced in the art of squatting. But researchers in China have come up with a new technology that they say can help eliminate one of the most noxious of problems to plague China’s public lavatories: the overpowering stench. 在中国，使用公共厕所往往是一件颇具挑战性的事情，对那些不能熟练深蹲的人而言尤其如此。但中国的研究人员发明了一项新技术，称这项技术能帮助消除困扰中国公厕的最严重的问题之一：刺鼻的臭味。 Unlike chemical solutions, which are expensive and can be harmful to the environment, the new biotreatment is being touted as an environmentally friendly, cost-effective way to resolve up to 75 percent of the odors in bathrooms, according to researchers with the Chinese Academy of Sciences. 不同于昂贵且可能危及环境的化学手段，这个新的生物处理办法被称为一种环保、经济的方式，中国科学院的研究人员称，这个办法能分解高达75%的公厕臭气。 The science behind the treatment lies in a special mixture of two types of bacteria — lactobacillius sp and streptococcus thermopiles — as well as the essence of tangerines. The prepared mixture, which comes in liquid or powder form, feeds on human waste when applied, thereby precluding the growth of aroma-making bacteria. 这一处理办法背后的技术原理涉及一种特殊的混合物，该混合物由两类细菌——乳杆菌类细菌和嗜热链球菌——和橘子香精组成。事先备好的这种混合物呈液体或粉末状，使用时会分解人类排泄物，从而防止长出会产生气味的细菌。 |
