Under a fixed model of chromospheric flare, we investigate the influences of Hα and CaIIK line profilles on various velocity distributions from semiempirical view. The results show that: Hα line is very sensitive to the velocity in upper chromosphere; the profile of CaIIK line have responses to velocity in any layer of chromosphere, but the degree of CaIIK line asymmetry is much weaker than that of Hα and can be ignored if velocity is as small as 10km/s; chromospheric condensation in lower part of transition region have strong influence on Hα line but contrary to CaIIK line, the typical characteristic of H line effected by chromospheric condensation in transition region is reversed blue asymmetry, i.e. the intensity of blue peak is stronger than that of red peak; the stronger the chromosphoric condensation is, the more obvious the Hα line asymmetry appears; and so on.

在确定的大气模型下，从半经验角度系统地研究了大气各个层次的速度场和运动结构对Hα和CaⅡK谱线轮廓的影响，得到；Hα线对色球上部速度场敏感，而对色球下部和温度极小区附近速度场不敏感；CaⅡK对整个色球速度场均有反应，但不对称性较Hα弱，且速度小于10km/s时不对称性很不明显；CaⅡK受过渡区色球凝聚的影响较弱，而Hα对色球凝聚十分敏感；色球凝聚影响Hα轮廓的典型特征是呈反转结构的兰不对称性，即兰峰强于红峰；色球凝聚越强，Hα不对称性也越显著：等。

Calcium deposits were localized on the vacuolar membrane and in the nucleus of nucellar cells at the early degenerative stage, then they were also observed on the plasma membrane including vacuolar membrane and nuclear envelope at the middegenerative stage.

初始衰退的珠心细胞，Ca〓主要分布于液泡膜上和核内；在衰退中期的珠心细胞中，Ca〓主要分布在核膜、液泡膜及质膜上；在严重衰退的珠心细胞，Ca〓仅存在于液泡中。

Whole-cellpatch-clamp technology demonstrated that VDPG (1g/L) had notsignificant effects on the delayed-rectified K~+ current, TTX-sensitive Na~+ current and high-voltage-activated Ca~(2+) current of rat dorsalroot ganglion cells. The fast transiet K~+ current of cottonbollworm dorsal DUM cells, the fast transiet K~+ current, Na~+ current andhigh-voltage-activated Ca~(2+) current of Periplaneta Americana dorsalunpaired median cells were also not significantly affected byVDPG at the same concentration. However, VDPG had significant effecton the fast transiet K~+ current of Pieris rapae. The VES had not significanteffects on the high-voltage-activated and low-voltage-activated Ca~(2+)current of rat DRG cells.

膜片钳电生理实验显示1g／L毒囊粗毒对蜚蠊DUM神经元的快瞬时钾电流、钠电流、高电压激活的钙电流，对棉铃虫快瞬时钾电流和大鼠DRG细胞延迟整流钾电流、TTX-S型钠电流、高电压激活的钙电流均无明显作用，却对菜青虫快瞬时钾电流有明显作用；电刺激粗毒对大鼠DRG细胞低电压和高电压激活的钙通道无明显作用。

但是这一古老真理并不只适用于田里的庄稼，它还是那些正经历着人生磨难的人的无限希冀：一段友谊的受挫会开启另一段崭新友谊的大门；此处失去的工作会提供彼处更好的工作机会；一个梦想的破灭会成为美好未来的基石。

The process of translocating Ca2+ from fruit surface into pulp tissue could be accelerated by IAA,GA or NAA, which also led to an increment on 2%HOAc extractable Ca. Meanwhile, the Ca existed in the stalk and leaves could be excessively transported into fruits by applying IAA on the fruit surface, resulting in too much accumulation of Ca in fruit and bad quality of fruit, while no such effects were observed in those with GA or NAA.

IAA、GA和NAA均可促进果面钙运往果实内，并导致2%HOAc提取钙与5%HCl提取钙组分增加，IAA虽可促进大量的树体钙向果实转移，却会导致果实钙含量过高，品质变差；GA和NAA则不能夺取树体内的钙，对果实品质无不良影响。
