The results showed that there were differences between adaption and regulation of different wheat varieties by prophyl dihydro jasmonate, so as to show diversity of gas exchange parameters, such as photosynthesis, water usage, etc. There was no evident difference between the reaction of two spring wheats (Jinchun1 and 1608) and the winter wheat (Xiaoyan 22) to PDJ. Different parameters of different wheat varieties had inequable reaction to different concentration of PDJ. Photosynthesis rate, water use efficiency and stomatal limiting value were enhanced when PDJ concentration reached a high degree. At the same time, leaf transpiration rate and stomatal conductance decreased. Therefore, wheat could maintain normal physiological activities while environmental conditions were changed.
结果发现,面对类似激素双氢茉莉酸丙酯调控下的不同品种小麦适应与调节存在差异,从而导致光合和水分利用等气体交换参数的表现也存在差异;两种春小麦(金春1号、l608)和一种冬小麦(小偃22)之间对PDJ的反应没有明显的冬春性间的差别;对不同品种、不同参数,PDJ起到作用的浓度不同,但无论如何PDJ都有相同的作用,当这种激素达到一定的浓度后,就会增强小麦的光合速率和水分利用率,增加气孔限制值,降低叶片的蒸腾速率和气孔导度,从而在外界条件变化时保持体内水分、延缓气孔关闭,维持体内正常的生理活动。

For example, IEEE 802.16e supports vehicle speed up to 120 km/hour, and IEEE 802.20 supports vehicle speed up to 250 km/hour. OFDM systems can be used efficiently in time invariant environments with one-tap equalizers. However, subcarriers are no longer orthogonal to each other in time-varying channels, and this causes the intercarrier interference and degrades the system performance.
传统的正交分频多工系统可以有效率地使用在非时变通道中,且仅需简单的等化器,即可修正通道效应,但在移动的环境中,通道随著时间改变,使得接收端的子载波失去正交性,因而导致子载波之间的相互干扰,使得解调变后的效能降低。

The results indicate that polyborazine precursor prepared at 150℃ for 10 h and propylamine/isopropylamine molar ratio 2:1, could possess nearly linear molecule skeleton and he prone to melt spinnability. When melt at 90℃, the precursor fibers are prepared with average diameter 10-20μm and BC1.27 N1.52 H structure. After curing process and sintered in NH3 at 1200℃, the near-stoichiometric BN fibers was obtained, which proved this precursor is apt for preparation of BN fibers.

In other words, we prove our working hypothesis related to immune hyper-activation within intestinal mucose during HIV infection by the studies.
而在HIV感染时,由于危险信号的释放,病毒子模拟APc的作用,调节性T细胞优先被删除等原因导致生理性低反应性状态被打破,而出现免疫过度活化,从而产生更多的HIV易感细胞,通过直接感染以及活化诱导细胞凋亡,使肠道T细胞在短期内大量丢失,从而导致免疫缺陷。

In the process of this item, after the mainly uncertainties affecting the network planning are detailedly researched, some flexible planning models such as Blind Number Method and Scenario Method are proposed. Because power network planning is a nonlinear, discrete, multi-peak, multi-objective and nondifferentiable problem, it is very hard to be solved. Ant Colony Algorithm is an advanced metaheuristic method and has potential to deal with network planning problems.

Many years ago, it have been noticed that, not all injurise of heart cell were directly proportional to the inflammatary reaction, and this kind of noninflammatory damage may be apoptosis. Kawano has verified first time in 1994 that, the onset and development of VMC accompanied the apoptosis, and the apoptosis probably are significant mechanism from VMC to the dilated cardiomyopathy.
早有人注意到,VMC时心肌损伤并不都与炎症反应成正比,其存在的非炎症性损伤很可能是细胞凋亡。1994年Kawano等首次证实心肌炎伴有心肌细胞凋亡,后者可能是心肌炎发展成扩张型心肌病的重要机制。
