这个问题太大了。工程塑料包括PA(66、46、6T、9T)、PBT、LCP、POM、PPS、SPS很多种。高温塑料主要就是46、6T、9T、LCP这几种，能够通过SMT制程；上述所有材料均能通过TH制程，但PPS在高温之后容易变色，SPS则是端子保持力不够。LCP性能比较优异，但其熔接强度很差，且价格较高。至于应用的话，那要根据塑胶特性来选择，当然跟产品结构也会有很大的联系。

给你一个网址http://baike.baidu.com/view/45821.htm或搜索工程塑料，查看工程塑料的百科就行。

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.
