下降了...

When the spaceship returned to start procedures to return module down to 15 km away from the ground, it was the pneumatic resistance attack it suffered gravity, a drop from supersonic speed reduced to subsonic and stability in the 200 米/秒 about time to slow down on the parachute on.

当飞船启动返回程序，返回舱下降到距地面15公里时，它所受到的气动阻力近似于它所受的重力，下降速度由超音速减到亚音速，并稳定在200米／秒左右，这时再减速就要靠降落伞了。

When applied -N amount was more than 300Kg/hm2, the contents of some cations, which effect on key enzymes of nitrogen assimilation, was declined significantly, thus, total-N decreased in leaves of swamp cabbage.

华南热带农业大学硕士学位论文 6、施氮量超过300 Kg月加2后，蔬菜叶片中影响氮同化关键酶活性的阳离子含量显著下降，影响了蔬菜对氮的同化，叶片中全氮含量下降。

The results show that total N, Cl(superscript -), organic matter, humic acid content of soil improves under vinasse treatments. Catalase and polyphenol oxidase activity increase abnormally at sugarcane settling stage and then sharply decrease to CK2 level at sugarcane maturity stage.

结果表明：蔗地施用废液提高了土壤全氮、Cl、有机质、腐殖质含量，使甘蔗苗期土壤过氧化氢酶和多酚氧化酶活性异常升高，随后迅速下降，成熟期下降到接近或小于CK2的土壤酶活性水平。

The results show that total N, Cl-, organic matter, humic acid content of soil improves under vinasse treatments. Catalase and polyphenol oxidase activity increase abnormally at sugarcane settling stage and then sharply decrease to CK2 level at sugarcane maturity stage.

结果表明：蔗地施用废液提高了土壤全氮、Cl-、有机质、腐殖质含量，使甘蔗苗期土壤过氧化氢酶和多酚氧化酶活性异常升高，随后迅速下降，成熟期下降到接近或小于CK2的土壤酶活性水平。

GA treatment restrained the respiration rate and ethylene production. 100mg.L-1ABA and 1000 L.L-1 ethephon evidently increased TSS and total titratable acidity acid content of green-mature fruit. The effect of ABA was more significantly than 1000 L .L-1ethephon, this suggested'ABA was the main hormone of influencing scenescence of'brumal jujube'fruit.

白熟冬枣采后冷藏过程中，内源ABA含量逐渐上升，贮藏后期有峰值出现；IAA和GA含量呈逐渐下降趋势；乙烯利和ABA处理都促进了内源ABA的积累和IAA和GA含量的下降，而ABA的作用比乙烯利明显；说明ABA调控果实的衰老是通过影响内源激素的变化而起作用的。

Most of the Italian monasteries had fallen under the influence of Cluny in the tenth and eleventh centuries, and had adopted its customs, but by the end of the fourteenth century they had so greatly declined that there was then hardly one left in which the Cluniac observance was retained.

大多数意大利寺庙下降的影响下，克鲁尼在第十和第十一世纪，并通过了海关，但在年底的14世纪，使他们大大下降，有那麼一个很难留在该Cluniac遵守被保留。

The results showed that: 1 The survival curve of the population conformed to the type of Deevey-Ⅲ; 2 With an increase in the population mortality ratio and a decrease in the survival rate, the mortality ratio greatly increased in ages 0-40 years, reaching 89.7%; 3 There existed two peaks of mortality in the lifespan, one was from seedlings to young trees (0-40 years) and the other in the adult stage (180 years).

结果表明：1岷江上游林线地段岷江冷杉种群存活曲线趋於Deevey-Ⅲ型。2林线地段岷江冷杉种群生存率呈单调下降趋势，生存率下降趋势前期高於后期，说明岷江冷杉种群幼苗死亡率高，种群后期比较稳定。3林线地段岷江冷杉林整个生长期中出现了两个死亡高峰期，一个出现在幼苗向幼树过渡时期（0~40年），另一个出现在中龄时期（180年）。

For example of atom of hydrogen, it must be enough surrounding electrons so can be form a "electron space", it could be form gravitation among electron and proton, at first whole gravitation line may acts with proton ,but if the quantity of electron go to much ,every one can got gravitation line from proton would be lower, the gravitation between proton and electron would be drop, when it is reached fixed lever, this power is equal to expulsive force which between electrons , so it would be reach balance, the electron can't much more.

之间形成引力，质子向外发出的引力线本来可以全部同外围电子作用，但是，电子多了，每一枚电子从质子分到的作用引力线便减少，它们同质子间的引力要下降，下降到一定程度，此力等于电子间的斥力，达到平衡，电子便不能再多。

The model of Alzheimer 's disease was made in Wistar rats by injecting the ibotenic acid into the bilatertal substantia innominata of rat brain. The content of t3 and the activity of T45-monodeinase in the rat brain was measured.

利用中枢胆碱能系统损害所致的Alzheimer病大鼠模型，测定了大鼠脑组织内源T3含量及T45－脱单碘酶活性，发现它们在90天时开始下降，180天时明显下降。

But the Central Weather Bureau says winds have decreased since Taiwan was pounded by Typhoon Krosa and it has been downgraded to a tropical storm, with sustained winds of 108 kph (66 mph), down from 184 kph (114 mph).

但中央气象局认为Krosa台风自从经过台湾已有减弱，他已下降等级到热带风暴了，她保持着从184kph（66哩/时）下降到108kph（114哩/时）的风速
