发帖数: 25 | 3 丰田的二手小车，开了5万多公里。前天车检发现左前方的shock absorber漏油，可能
漏的时间比较长了，shock absorber的表面都沾了一层油泥，修车的建议换掉，说
shock absorber也是消耗品，4，5万公里后会因为摩擦，振动等原因出现漏油等情况。
我想如果是这样的话估计右边的寿命也差不多了，请问shock absorber的寿命大概有多
长，是否有必要一起换，谢谢。
另外我想过段时间再换，如果这么将就着开，对车是否有什么影响，每天开20公里左右
，非高速。 |

My guess bacteria don't have pigments that absorb at 600nm but does have
pigments that absorb at these lower wavelength.
Just my guess. |

When measuring light scattering it is important to consider the wavelength
of light used a bacterial culture. Microorganisms may contain numerous
macromolecules that will absorb light, including DNA (254 nm), proteins (280
nm), cytochromes (400-500 nm), and possible cell pigments. When measuring
