Question

哪位高手能翻译一下

Follow the 1989 Exxon valdez oil, 100 km of Arctic shoreline was contaminated. Crude oil is made up of thousands of compounds.It takes many different kinds of naturally occurring bacteria to break the oil down. Lab technicians identified and counted the bacterica. They monitored how well the oil was degrading. More bacteria and less oil were sign that the shoreline was recovering. The number of bacteria needed tto effectively break down an oil spill is 1000000per millilitre of oil. The bacteria double in number every two days. The starting concentration of bacteria is 1000 bacteria per millilitre. This situation can be modelled by the equation C=1000(2d),Where C is the estimated concentration of bacteria and D is the estimated concentraction of bacteria and D is number of 2-days periods the bacteria to reach the required concentration?

Answer 1

按照1989年的埃克森公司瓦尔迪兹石油，100公里的北极海岸线被污染。原油是由数compounds.It利用天然细菌，打破了许多不同的石油千种。实验室技术人员鉴定，并计算bacterica。他们监视得怎么样油降解。更多的细菌和少油的迹象表明，海岸线正在康复。所需要的格子有效分解细菌数量的石油泄漏的石油是1000000per毫升。这种细菌在数量上翻一番两天。细菌的起始浓度为每毫升1000个细菌。这种情况可以模拟由方程C = 1000（二维），其中C是细菌浓度估计，D为估计浓度下的细菌和D为2天的周期数的细菌，达到所需的浓度是多少？

Answer 2

手翻

1989年埃克森石油公司在瓦尔迪兹城漏油事件之后，北极圈中100公里的海岸线受到了污染。 原油是由数以千计的化合物组成的， 如果要将原油分解的话，需要多种自然形成的细菌。 实验研究者鉴定且数了这些细菌。研究者记录了那些油的化解进度，更多的细菌和减少的原油就说明海岸线的生态正在恢复。需要有效地分解这些漏的原油，每一毫升的油就需要100万个细菌。这些细菌的数量每两天翻一倍。初始的细菌浓度时一千细菌每毫升。这个形势可以用等式
C = 1000(2d)，C是估计的细菌浓度，d是多少个两天周期（细菌增倍时间）直到细菌浓度达到需要分解原油的浓度。
