人类排泄物

An acceptable and practical system for the disposal of human excreta is the key to reducing health hazards.

降低对健康威胁的关键，在于建立可以接受的、实用的人类排泄物处置系统。

Inadequate disposal of human excreta is a major health risk in emergency situations.

在紧急情况下，人类排泄物的不适当处置是一个主要的健康危害。

Human waste is more dangerous than animal waste; therefore, the safe disposal of human excreta is more important than the disposal of animal waste.

人类的排泄物比动物的更危险，因此，人类排泄物的安全处理比动物的更重要。

Selling human waste products as fertilizers became much less common after World War II, both for sanitary reasons and because of the proliferation of chemical fertilizers, and less than 1% is now used for night soil fertilization.

二战以后，将人类的排泄物作为肥料售卖变得很少见，出于卫生的考虑及化肥的普及，直至现在，只有不到1%的人仍在用农家肥。

In communities where storm drains feed into sewer pipes, heavy rains can cause overflows that dump untreated human waste into rivers, lakes and bays.

在某些社区，雨水沟的水会流入下水道，于是豪雨一来，尚未处理的人类排泄物就会溢出，流入河流、湖泊和海湾。

They did it by taking ten-week-old mice that had been bred to be free of germs and colonising their guts by feeding them with human faeces.

他们通过给初生的老鼠喂食无菌的食物，然后在他们长到10周大的时候通过给它们喂食人类排泄物在其内脏植入人类细菌。

They did it by taking ten-week-old mice that had been bred to be free of germs and colonising their guts by feeding them with human faeces. Note to the squeamish: the article adds that mice are coprophagic.

他们培养了年龄为十周的肠道内无菌的实验老鼠，之后在它们的肠道内移植了人类排泄物（备注，虽然这句看起来有些恶心，但是，文章指出，老鼠和苍蝇一样有着Coprophagia-食粪性）。

Infected ducks then release large quantities of the virus in pathogenic form in their excretions spreading the virus to other birds or humans.

感染鸭，然后释放大量病毒致病形式，其排泄物传播的病毒传染给其他鸟类或人类。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
