The TPA cross section at 800 nm is about 12.5×10^(-22)cm^4/GW. These results suggest that the excited state S2 populated by TPE or OPE may relax via radiationless process to the fluorescence state induced by OPE of Q band, and then show a normal fluorescence emission behavior. The large TPA cross section may result from the intensive linear absorbance of the molecule due to its conjugate rigid plane structure, and the two-photon resonance excitation condition. These photophysical properties of CPD 3, suggest that the chlorphyll derivatives, as the class of new photosensitizers for photodynamic therapy, may be also the excellent two-photon molecular probes for studying the interaction between the photo-sensitizer and the inner parts of tumor cell in PDT by means of two-photon fluorescent microscopy and imaging, in order to make it possible to understand the mechanism of PDT on the molecular level.

Furthermore, the velocity vectors in the gas channel and gas diffuser of a PEM fuel cell with parallel flow field also point from the anode side to cathode side. 2. Because of the dead-ended structure of interdigitated flow field, the velocity vectors always point from the inlet gas channel to the outlet one at any cross flow plane, which have a increase of more than 10 times than those in the gas diffusion layer of a PEM fuel cell with parallel flow field; as a result, the water concentration fraction and water saturation in the former fuel cell is much less than that in the same region of the later one, which reduces the concentration overpotential derived from the oxygen mass transport largely and increases the oxygen concentration fraction in the gas diffuser of a PEM fuel cell with interdigitated flow field greatly to enhance electrochemical reaction rate; however, higher gas velocity can carry much more water out of the flow field, hence, the cathode humidification is important for an interdigitated flow field to acquire a better performance than a conventional flow field does.
在交指型流场燃料电池中，由于流场的末端封死结构，使气体的传递机理改变为强迫对流形式，速度矢量总是从进气流道经由气体扩散层指向排气流道，从而使得交指型流场燃料电池的气体扩散层中的速度大小较之平行流场燃料电池气体扩散层中的速度要大10倍以上，因此前者的扩散层和流道中的水的质量浓度分数以及液态水的饱和度较之后者要小的多，这大大减小了电池中由于氧气传质引起的浓差过电势，从而使交指型流场燃料电池的气体扩散层中的氧气浓度分数较之平行流场燃料电池气体扩散层中的浓度分数要大得多，增强了电化学反应速率；然而，由于高速流体带出较多的水会使膜电阻增加，因此只有对电池阴极进行增湿，交指型流场燃料电池的性能才会优于平行流场燃料电池的性能。3。

Chickens of Con group were fed ad libitum throughout the experiment for 9 weeks, while chickens of EFR and LFR groups were subjected to intermittent feed restriction with feed provided on alternate days for the first and the last 2 weeks of their posthatch life, respectively. Chickens from each group were sacrificed at 14 d and 63 d. Serum thyroid hormone concentration were measured and the lateral gastroenemius muscle were taken for measuring the cross-sectional areas and densities of each type of myofibers using H.
