Using whole-cell patch clamp recording, we observed multiple distinct ATPinduced currents in isolated DRG neurons of adult rats, each with unique desensitizing kinetics.β,γ-meATP, agonist of P2X1 receptor also induced fast inactivating and slowly desensitization current in small DRG neurons. PDBu, a selective agonist for PKC, decreased the P2X receptor-mediated inward currents in a dose-dependent manner, while SNP, nitric oxide donor, potentiated the ATP-evoked current through NO-cGMP pathway.

When oxygen is absent, the heat treatment has a negative effect on the activity of the carbon, and the deeper heat treatment results in the lower activity, which is directly relevant to the decrease of the amount of C-OH which plays an important role in the reduction of NO with carbon.

在无氧条件下，活性炭热处理降低了其还原NO的反应活性，且其反应活性随着热处理程度的加深而降低，这与炭表面C-OH数量的减少有直接关系，C-OH在C-NO反应中扮演了重要角色。

The particle roping mechanism in a coal conveying pipe with large diameter was also studied with the fiber probe. The on-line coal concentration measuring facility is needed for NO〓 reduction. In this work, a set of on-line coal concentration measuring facility was developed and installed in the coal conveying pipes of a 660MW capacity utility boiler, which can give on-line accurate coal concentration information for the operator.

论文首次采用基于光学波动法的激光光纤探针，对高浓度的低NO〓燃烧器出口的气固两相流动的详细结构进行了试验，研究了配300 MW煤粉燃烧锅炉的燃烧器出口高浓度气固相射流中颗粒浓度、粒度随射流发展的演变规律，分析了利用水平浓淡燃烧器和齿形燃烧器实现对低NO〓燃烧有利的气固结构，并验证了基于DES方法的气固两相数值模拟的计算结果。

The maxillofacial and brain injuries were examined. Craniptomy was done to animals of impact injury 6 hours after damage, however it was done to animals of explosive injury in different time point (1 hour, 24 hours, 72 hours, 7 days, 14 days after damage). The pathological characteristics of corelative tissues were examined in detail under light and electron microscopes. The content of LPO, SOD, NO in soft tissue, brain, blood, and cerebral water content were measured, compared with control. The distribution and tissue location of NOS were studied by histochemistical and immunohistochemistic methods. Their relationship was studied to assess the pathological and physiological characteristics of maxillofacial injuries and brain damage associated.

The ion concentrations were studied in both four snow pits on Hami Miaoergou FlatTopped Glacier and one snow pit on Haxilegen Glacier No.51 of Kuitun river in eastern Tianshan Mountain, and both snow pits were retrieved in 2004. The results show that the Ca2+, NO-3 and SO2-4, particularly Ca2+, are major ions in the snow of snow pits in both ablation and accumulation area and also in the ice of snow pits in accumulation area on Hami Miaoergou FlatTopped Glacier, where the relationships among major cation concentrations in snow of snow pits can be revealed by ion concentrations in the ice of snow pits, but the correlation between ion concentrations in the snow of snow pits and elevation is not obvious, which probably can be attributed to the narrow span of elevation and sparse snow pits on glacier. However, the good correlation between ion concentrations in the ice of snow pits and elevation indicates that the elution process weakened gradually with the elevation rise and temperature decrease.

对2004年获取的天山奎屯河哈希勒根51号冰川1个雪坑和哈密庙尔沟平顶冰川4个雪坑的离子浓度特征进行了研究，结果表明：Ca2+、NO-3和SO42-是哈密庙尔沟平顶冰川雪坑雪层和积累区雪坑底部冰中的主要离子（尤其是Ca2+），其雪层中的主要阳离子关系可在底部冰中得以较好的反映，但雪层中各离子浓度与海拔的相关性不明显，可能与海拔的跨度较小和挖取的雪坑较疏有关；雪坑底部冰中的离子浓度与海拔间明显的相关性说明淋融作用随着海拔升高、气温降低而逐渐减弱。
