Challenge was made after one month of immunization by vein. Re sults:The parasitemia of recombinant virus immunized monkey was 0.0 1%in first tw o days of post-challenge. No parasites were determined from third to 12th day. W hereas the parasitemia of control virus immunized-monkey and blank control monk ey rose progressively,went to 2.5%～6.0% at 6th～8th days of post-challenge, an d the t ime of parasitemia was 12～13 days.

结果： 在免疫后1个月攻虫，重组痘苗病毒免疫猴从第3天一直到第12 d的采血检查中均未发现疟原虫；非重组痘苗病毒免疫猴第3天后原虫感染率上升，第6天原虫感染率最高达到6.0%，而后原虫感染率逐渐下降，原虫持续时间为13天；空白对照猴第3天后原虫感染率也上升，第8天原虫感染率最高达到2.5%，而后原虫感染率逐渐下降，原虫持续出现时间为12 d。

While the tissue spaces surrounding a few blood vessels wasAl and Fg positive,no Al or Fg positive cells were observed.In antemortem injurygroup,diffuse subarachnoid hemorrhage,cerebral edema,swelling or pyknotic neu-rons could be observed.The axons showed irregular swelling and disconnection at1～3h,marked swelling and disconnection at 6h,and retraction ball at 15h whichwas more remarkable at 24h after injury.The space between myelin sheaths andaxons was increased at 3～6h after injury.Tortuous and wavelike myelin sheathswhich adhered on axons incompletely,or even peeled off could be found from 15hto 24h after injury.Perinuclear lysis of Nissl bodies began at 24h after injury.Thenumber of GFAP positive cells in cerebrum and brain-stem increased significantlyfollowed by decrease,and then increased again,but the time courses of the changesin different areas of brain were not same.Al and Fg positive neural cells,mainlysurrounded blood vessels,with diffuse or peripherally distributed positive matter incytoplasm could be observed at 0.5h after injury.The number of Al or Fg positivecells and the intensity of immunoreaction increased with the time of injury.The areaof SYN positivity in medulla oblongata and pons decreased notably 3～6h afterinjury,then return to normal levels and continued to 24h after injury.

生前损伤组，可见广泛蛛网膜下腔出血，脑组织水肿，神经细胞肿胀，晚期神经元固缩；伤后1～3h见部分神经轴突不规则增粗、断裂，伤后6h断端膨大，伤后15h可见收缩球，至伤后24h更为明显；伤后3～6h可见部分神经髓鞘与轴突之间的间隙增宽，伤后15h髓鞘明显曲折，不完全附着在轴突两侧，甚至剥脱，持续到伤后24h；核周尼氏体减少在伤后24h才开始出现；同一部位的GFAP阳性细胞数目随损伤时间发生改变，先增多（最早在伤后0.5h），达到高峰后减少，其后又有增多趋势，但不同部位的GFAP阳性细胞数目增减的时间过程不尽相同，同时，大脑中的GFAP阳性细胞数目也有改变；伤后0.5h，可在脑干组织中见到Al和Fg阳性神经细胞，主要位于血管周围，阳性物在胞浆中呈弥散性分布，但部分细胞的阳性物仅分布于靠近胞膜的胞浆中而呈环状，随损伤时间延长，阳性细胞数目增多，反应强度增加；伤后3～6h，延髓及桥脑中的SYN阳性物面积减少，其后恢复到正常水平，并持续到伤后24h。

The duration field of the spell determines how long units take damage over time and how long it takes to be able to reattack the same target again.

通过调整持续时间可以设定一个单位受伤害的持续时间以及同一单位受到两次伤害的时间间隔。

The temperature affects the sustained time of secondary sporogenous cell split, the sustained time of microspore mother cell, formation speed and regular of male gametophyte.

温度影响次生造孢细胞持续分裂的时间、小孢子母细胞的持续时间及雄配子体的形成速度和整齐度。

Over a 20-year period there was no increase in soil water content in the grazed grassland at depths of 2～9.9 m. There was a small increase(0.5～3.7 mm/a) in soil water content in the protected grassland, however the slow rate of increase suggests that at least 150 years would be needed for ungrazed grassland soils to regain water content similar to that present prior to planting trees. Recharge of deep soil moisture was faster in cropland(15 mm/a), but at this rate it would still take about 40 years to restore cropland soil water content to pre-plantation conditions.

结果表明，人工林死后的放牧荒坡在20a的时间里，其土壤水分没有补偿；人工林死后的保护草地土壤水分有微弱恢复迹象，但年恢复速度在0.5～3.7 mm之间，以这样的速度恢复到持续放牧荒坡的土壤含水量，至少需要150a以上；林后农地土壤含水量有恢复趋势，年平均恢复速度为15 mm左右，其土壤含水量要恢复到持续农地当前的水平，大约需要40a的时间。

The fallowing are the main conclusions:(1) The time of arable land resource sustainable use change with any factor of the agro-ecology-economic system. The temporal model of arable land resource sustainable use is dynamic model.

主要结论是：(1)耕地资源可持续利用时间随着系统相关影响因子的变化而变化，耕地资源可持续利用的时间模型是动态模型。

Corresponding to the long-lasting El Nio event, cyclonic anomalous circulation over the eastern North Pacific weakens slowly and anticyclonic anomalous circulation over the western North Pacific strengthens slowly at 850 hPa. Therefore the tropical Pacific westerly anomaly keeps long. The anomalous positive velocity potential over the western South Pacific at 200 hPa, which is related to the strong Australian winter monsoon, helps a long duration of El Nio. Corresponding to the short-lasting El Nio, the anomalous positive velocity potential over the western Pacific at 200 hPa moves eastward quickly and results in the vanishing of El Nio event.

还发现对于持续时间较长的El Nio事件，东北太平洋上850hPa异常气旋性环流减弱和西北太平洋上异常反气旋性环流增强较慢，因此赤道太平洋异常西风维持的时间也较长，而与澳大利亚冬季风加强相关联的南半球西太平洋的速度势正距平的维持，对El Nio的持续也起一定作用；对应持续时间较短的El Nio事件，西太平洋上200hPa速度势正距平的迅速东移，对El Nio的迅速消亡起重要作用。

In tests of single DNA bases, the dark state lasted for 10-150 picoseconds -- much longer than the bright state. The chemists reported their results in the Proceedings of the National Academy of Sciences.
