A research team from Southwest PetroleumUniversity in Sichuan Province has developed a low-cost, high-efficiency photocatalyst that uses visiblelight to purify water.
日前,四川省西南石油大學(xué)的一個(gè)研究小組研發(fā)了一種低成本、高效率的光催化劑,這種催化劑可以利用可見光來凈化水質(zhì)。
A photocatalyst is a substance that can help cause alight-catalyzed reaction, such as chlorophyllcapturing sunlight to turn water and carbon dioxideinto oxygen and glucose in photosynthesis.
光催化劑是一種可以能夠引起光催化反應(yīng)的物質(zhì),比如葉綠素可以捕捉陽光,在光合作用中將水和二氧化碳轉(zhuǎn)化為氧氣和葡萄糖。
Ordinary photocatalysts can decompose organic pollutants in sewage under ultraviolet light, which, however, only accounts for four percent of the solar spectrum, making this type ofsewage treatment costly and preventing it from widespread application.
普通的光催化劑可以在紫外光下分解有機(jī)污染物,然而,紫外光只占太陽光譜的百分之四,使得這種污水處理的成本很高,并阻礙了它的廣泛應(yīng)用。
The research team of eight doctoral students turned to visible light, a spectrum accountingfor 43 percent of sunlight. After four months of research, they developed a new photocatalystReac-O2 with good visible light absorption performance.
于是,由八名博士生組成的這個(gè)研究小組將目標(biāo)轉(zhuǎn)向了可見光,這種光譜占到了43%。經(jīng)過四個(gè)月的研究,他們開發(fā)出了一種具有良好可見光吸收性能的新型光催化劑Reac-O2。
Reac-O2 can produce reactive oxygen species, purifying water by degrading organicpollutants into non- or low-toxic small-molecule substances.
Reac-O2可以產(chǎn)生活性氧,通過將有機(jī)污染物降解成無毒或低毒的小分子物質(zhì)來凈化水。
In experiments, the new photocatalyst performed more efficiently than traditional sewagetreatment agents.
在實(shí)驗(yàn)中,新型的光催化劑比傳統(tǒng)的污水處理劑更高效。
"The amount of water that used to be purified with one hour now can be purified in just 30 minutes," said Shi Xian, head of the research team.
研究小組負(fù)責(zé)人石晛表示:“過去花一小時(shí)才能凈化的水,現(xiàn)在只需30分鐘。”
Reac-O2 can be recycled at least 30 times and maintain a degradation rate of 85 percent.
Reac-O2可以再循環(huán)至少30次,并保持85%的降解率。
Using Reac-O2 to purify a ton of sewage will cost five yuan (0.73 US dollars) while usingtraditional technology costs 17 yuan, said Shi.
石晛稱,使用Reac-O2凈化一噸污水需要5元(0.73美元),而使用傳統(tǒng)技術(shù)則需要17元。

The travel agency's study tour business has grownimpressively in recent years.
近年來,攜程的游學(xué)業(yè)務(wù)增速驚人。
Those choosing tours abroad grew by 50% during the 2017 summer and the 2018 wintervacations year-on-year. The tours on average cost about 29,000 yuan each.
2017年暑假及2018年寒假期間,選擇進(jìn)行海外游學(xué)的人數(shù)同比增長(zhǎng)50%,人均游學(xué)費(fèi)用約為2.9萬元。
Those opting for domestic study tours grew by 120%, with costs pegged at about 4,200 yuan.
選擇國內(nèi)游學(xué)的人數(shù)增長(zhǎng)120%,人均費(fèi)用約為4200元。
The UK, the US, Australia, Singapore, New Zealand, Canada, Japan, Thailand, Indonesia andFrance are among the most popular destinations among Ctrip users.
英國、美國、澳大利亞、新西蘭、加拿大、日本、泰國、印度尼西亞和法國是最受攜程客戶歡迎的目的地。
Domestically, Ningxia, Inner Mongolia, Guizhou, Qinghai, Shanghai, Beijing, Yunnan, Sichuanprovince's Chengdu, Guangdong province's Guangzhou and Shenzhen are the most appealingin China.
國內(nèi)方面,寧夏、內(nèi)蒙古、貴州、青海、上海、北京、云南、四川成都、廣東廣州和深圳最具吸引力。

這一行動(dòng)正值中美兩國持續(xù)發(fā)生貿(mào)易摩擦之際,引發(fā)了廣泛的討論,即中國應(yīng)該在核心技術(shù)方面更加獨(dú)立和創(chuàng)新,尤其是在學(xué)術(shù)研究領(lǐng)域。
