常見的LD 半導體激光器，分單管和巴條BAR兩種。巴條功率更高些

Microbial mapping The intensity of resonance Raman spectra of Cyt c allows for integration times below one second. Microbial mapping of an area of 50×50 μm2 with a resolution of 500 nm/pixel (10，000 single spectra) can be performed in less than 3 h. A further reduction of the measuring duration by a factor of 10 can be achieved by utilisation of an EMCCD camera (Coates et al.， 2004). Microbial mapping was done on granules from two different sequencing batch reactors (SBR) (Gaul et al.， 2006). The SBRs are used to analyse control parameters for the anaerobic ammonium oxidation. Fig. 7 shows two different microbial colonies in the same granulum. A graphical analysis of the spectroscopic data at 750 cm-1 (dominant resonant Raman band of Cyt c) and 2900 cm-1 (CH stretching mode) differentiated the two colonies. One colony shows stronger Raman signals at 750 cm-1 (blue frame). Whereas the other microorganisms have more amount of methyl or methylene groups (yellow frame). After the graphical analysis above， an average spectrum was constructed for each colony. The resulting averaged spectra were transferred to our Raman database of wastewater bacteria created by OPUS. The software recognized the microorganisms Fig. 5. Time series of N. eutropha Nm 57 which is captured by optical tweezers. Time difference between spectra: 1 s; Laser power: 9 mW. The bleaching effect due to photo-dissociation caused by laser radiation is easy to see. Fig. 6. The spectral heterogeneity of hierarchical clusteringis strongly dependent to the integration time. Bacteria from the same strain are only groupedtogether if the exposure time was the same. 246 R.

哪位高手能幫我簡述固相肽合成技術: 哪位高手能幫我簡述固相肽合成技術，我對這方面一無所知啊，但是急用啊.謝謝啦

哪位專家能幫我講解一下電渦流振動傳感器？:

靜電屏蔽導體空腔問題: 空腔中無自由電子的移動，所以就不會受外部場強的影響而導致自由電子的移動，從而不能確定空腔內場強是否抵消為0. 導體內部的電子的自由移動，是因導體內部受的場強，平衡時只能保證導體內部場強為0，并不能說空腔內場強也為0啊。那為什么書上說空腔內場強也為... 空腔中無自由電子的移動，所以就不會受外部場強的影響而導致自由電子的移動，從而不能確定空腔內場強是否抵消為0. 導體內部的電子的自由移動，是因導體內部受的場強，平衡時只能保證導體內部場強為0，并不能說空腔內場強也為0啊。那為什么書上說空腔內場強也為0.希望從自由電子的角度來解釋。呵呵，打得有點多，謝謝了。展開
