Recent documents suggested that either h2o2 or no function as signal molecules to mediate aba - induced stomatal closure in guard cells , but there was no report to study on the relationship between h2o2 and no in aba signal transduction pathway 最近的研究结果显示h _ 2o _ 2和no都能作为信号分子介导aba诱导的气孔关闭过程，但有关h _ 2o _ 2和no在aba信号转导途径中的相互关系知之甚少。
When the automatic door is placed in the close process in , if meet the strong breeze bar , the control system will carry on the power adjustment , the exaltation motor dint , make a close to shut to match , can the dust palliative and cold and warm electricity charges 当自动门处于关闭过程中，如遇强风阻碍时，控制系统会进行功率调整，提高马达力，使门扇紧密闭合，可防尘及冷暖电费。
Here , using stomatal analysis and laser scanning cofocal microscope techniques , we show firstly that no as the downstream intermediate of h2o2 signaling mediates aba - induced stomatal closure in viciafaba l . sodium nitroprusside ( snp , a no donor ) and h2o2 could mimic the effects of aba on stomatal closure 由aba或h _ 2o _ 2所诱导的蚕豆气孔关闭过程可部分地被no的专一清除剂c - ptio所逆转，而h _ 2o _ 2的清除剂过氧化氢酶( cat )则不能逆转no诱导的气孔关闭过程。
Chapter 3 focused on those key technologies used in hse , such as time synchronization , communication flow control , virtual address management , etc . using finite state machine model , setup and release processes of virtual communication channels provided by hse were particularly studied 第三章结合hse通信栈模型，对hse通信栈的时钟同步、流量控制、虚拟标识管理等关键技术进行了深入的研究。通过有限状态机模型，分析了hse通信栈连接的建立过程和关闭过程。
A does - dependent study of the aba - induced oxidative burst was observed , in which both the magnitude and rate of dye quenching was directly related to the concentration of aba . and the treatment of the guard cells with catalase of 100 units / ml nearly completely obliterated the quenching reaction induced by 10 | amol / l aba ( final concentration ) 因此， aba可以诱导气孔保卫细胞产生h2o2 ，其产生的强度和速度与aba的浓度直接有关，并且推测：这种h2o2产生可能是aba诱导气孔关闭过程中信号转导链的一个中间成分。
Furthermore , when 10 imo il h2o2 ( final concentration ) was added to the suspension after above treatment caused little reduction in hpts fluorescence . the results obtained by laser scanning confocal microscopy suggested that addition of exogenous aba resulted in a rapid decrease in fluorescence in most cellular compartments of the guard cells 维生素c可部分逆转低浓度h2o2 ( 10 - 5 )所诱导的气孔关闭过程：并且10 - 6mol l的dpi和103u ml的过氧化氢酶( cat )在一定程度上也逆转了aba诱导张开气孔的关闭。
Statistics and analysis of amplitude domain parameters of the vibration acceleration signal measured during closing of the pump valve shows that , by using this diagnosis method , the feature information of the pump valve failure can be extracted effectively , and the failure information features are rather obvious 通过对测取的三缸泵阀箱上泵阀关闭过程振动加速度信号的幅值域多参数的统计分析证明，采用振动信号幅值域多参数诊断法可有效提取泵阀失效故障的特征信息，且故障信息特征非常明显。
The aims of this mastered work are to show the changes in dimension and distribution density of particles , and the corresponding changes of ph as well in gcv during the stomatal closing , a ) the stomatal closure is induced by aba , and the sap in gcv of open and closed stomata is directly sampled with glass micro - capillary 本论文的目的是要获得气孔关闭前后保卫细胞液泡内颗粒状物在线度和分布密度上的变化以及在气孔关闭过程中保卫细胞液泡中ph的动态变化，并将结果与气孔开放过程获得的研究结果相比较。
Changes in h2o2 generation in guard cells of vicia faba induced by aba were measured by using fluorescence probe , 8 - hydroxypyrene - l , 3 , 6 - trisulfonic acid ( hpts ) . examination of epidermis peel was performed using a laser scanning confocal microscope ( lscm ) and spectrofluorometer , set to an excitation light of 405 nm and an emission light of 512 ran 以蚕豆叶片下表皮为材料，将荧光探针hpts导入蚕豆气孔保卫细胞内，利用荧光光谱和激光共聚焦显微镜技术，检测了aba诱导蚕豆气孔关闭过程中h2o2的产生。
This new method will bring significant developments in studying the principles of stomatal movement , and other quick movement in plants , c ) guard cells are incubated with ph dependent fluorescent chemical probe " bcecf am " and excited at 488nm , the fluorescent emission ratio method ( 520nm / 640nm ) is employed with laser scanning confocal microscopy , about 0 . 4 ph unit increase in guard cell vacuoles is observed during stomatal closure that is induced by aba 本发展为保卫细胞与其它小细胞液泡的进一步研究提供了新思路。 c )本工作通过激光共聚焦显微术配合ph荧光探针bcecfam的单激发( 488nm )双发射的荧光比值法( 525nm 640nm )观察到，用aba处理的表皮条上的开放态气孔在关闭过程中其保卫细胞液泡内ph有一约0 . 4单位的上升。
