The spectrum of fiber Bragg grating can be controlled by double exposure technique. The first exposure is used to control the resonant wavelength of fiber grating by directly irradiating the naked photosensitive fiber.

该方法只使用普通Bragg位相模板，采用两次曝光技术，通过控制光纤光栅的本地谐振波长和反射率，达到控制光纤光栅谱形的目的。

Results The longer time of exposure to the 150V/m electric field, the more electrotaxis the cells showed, that is, the distance of cellular migration increased obviously with the time of exposure to the electric field compared with control group.

结果 ①150V/m电场长时间作用下，培养的血管平滑肌细胞有明显的电场趋化性，细胞向负极迁移的距离明显高于无电场作用的对照组。

The endermic LD50 to rat and mouse were 926 mg/Kg and 1210 mg/Kg respectively. The results of subscute toxicity test in rats showed that the content of blood urea nitrogen in exposure groups was higher than that in control group, the histopathological changes of testis observed in exposure groups were obvious. Mutagenic tests including bacillus subtilis DNA rec-assay, micronucleus ...

其大、小鼠经皮LD_(50)分别为926mg/kg和1210mg/kg；大鼠90天经皮染毒，试验组BUN含量高于对照组，光镜下，试验组睾丸的组织学结构有明显改变；枯草杆菌DNA重组试验、小鼠骨髓多染红细胞微核试验和小鼠睾丸染色体畸变分析试验均获得阳性结果。

The appearance of firefighter's clothing after flame engulfment was also analyzed. The analysis indicated that the more integrity the inner layer of clothing had after exposure, without brittleness and shrinkage, the more protection the clothing was. At the same time, the accessories on the firefighter's clothing were also crucial, especially for membrane and retro-reflective stripes. If they shrink in the exposure of flame, the protection of the clothing would reduce.

由检验各消防衣的外观来分析，则可知如果使用的材料在进行火焰冲击时，能够使防护衣仍具有完整的结构，且不产生脆化与收缩，则愈具有防护能力；同时对於消防衣上的零配件也要格外注意，尤其是薄膜与反光条，若此处产生热收缩，就会减低消防衣的防护能力。

As you mentioned, with most reported long incubation periods (especially from countries with enzootic canine rabies) there is always a question about other more recent exposures than the !0causative!1 exposure reported. Generally speaking, most incubation periods fall within 20-90 days following exposure, with the incubation period decreasing with the severity of the bite and proximity to the head.

你提到的，大多数的长潜伏报道（特别是犬类狂犬病盛行的国家），总是有一个问题的，就是真正引起患者死亡的，是新近一次感染，而不是所报道的那次感染。

You 'd better consult the exposure meter if you are not sure of the time for exposure.

如果你把不准曝光时间，最好查一下曝光表。
