Remember it takes considerable time and distance to reach high speed: if terminal velocity is 180 km/h, it takes 6.1 seconds (151 m) to reach 150 km/h in free fall, while to reach 170 km/h takes 9.1 seconds (283 m).

The main characteristics include: the quiet Sun corona has a rapid response to the flare heating, within 2 second the corona temperature increases nearly one order of magnitude, but later such increase becomes very slowly; the downward velocity at early stage of impulsive phase is too small to be negnected; chromospheric evaporation made by conduction shows some intensely, the maximum evaporated velocity may be as large as 1000 km/s; the chromospheric condensation appears just when the chromospheric evaporation takes place and its place always coincide with that of transition region in the early stage; the maximum of chromospheric condensation occurs also in the early stage of impulsive phase, at which the density in condensation may be larger two order of magnitude than that of surround and the downward velocity may be as large as 100 km/s; after the maximum of chromospheric condensation, its strongth decreases gradually but its width becomes greater with time and have a tendency to transport into deep chromosphere; the front of chromospheric condensation heats atmosphere obviously and the temperature in the chromospheric condensation is higher than the original case; the downware velocity of transition region may be greater than 100 km/s at the early stage; when the evaporated material collide at the top of loop, the densityand the presure there increase rapidly, which result in the formation of a shock wave; and so on.

在改善色球辐射损失和精确分辨过渡区的基础上，通过联立求解连续性方程、动量方程和能量方程，构造了一维磁限制性耀斑环在热沉积作用下的大气动力学模型，获得了耀斑热模型下脉冲相早期较为细致的大气演化理论图象，其主要特征是：耀斑对宁静日冕的加热相当迅速，仅2秒钟日冕温度增加即达一个量级，之后日冕温度增加缓慢；脉冲相早期日冕向下速度很小，几乎可以忽略，热传导驱动色球蒸发，其过程较为激烈，蒸发极大速度可达到1000km/s；色球压缩区与色球蒸发几乎同时形成，且在早期其位置总是与过渡区位置重合；色球压缩极大发生在脉冲相早期，其时密度可高于周围约2个量级，向下速度可超过100km/s；色球压缩极大后，其强度逐渐减弱，但宽度明显增大，且渐渐脱离过渡区往色球传播；压缩区内物质温度要高于原先的大气温度；过渡区下降在脉冲相早期相当迅速，可超过100km/s；当蒸发物质在环顶高速相碰时，环顶的密度、压力迅速增大，且温度也有所增加，导致形成激波，其波面以每秒上百公里的速度自环顶向下传播；在脉冲相前期，日冕软x辐射对色球的加热作用可以忽略；等。

As a side note, i recently took a drive to a nearby city, about 500 km away and 4800ft of change in elevation...on the way "up" theres a sudden change in elevation for about 100 km but maybe 3000ft elev....i was in a hurry and i was at full throttle almost for the entire trip, and when i reached that steep incline, the rogue slowed down from 150kmph to 120 kmph, even if i had the pedal to the floor, it wont go faster...only after a 45 minutes period of 120kmph it started gaining speed again but didnt reach the 170kmph as i have seen before...when driving back there was no problem at all, even when i was again at full throttle most of the time...both times i was the only occupant of the vehicle on daytime driving and straightways about 50 km long...

附带注记一下。最近我开车到附近的一个城市，路上大约 500 公里远，在约 100 公里内的爬升 4800ft海拔的突升变化，但也许 3000ft 海拔。。。。我是匆忙以及我是在几乎为在整个的旅途的完整节流，我到达该陡峭的斜坡，rogue 速度开始下降，从 150 kmph 到 120 kmph，即使我将油门脚踏它到底，它并没走得更快。。。持续45 分钟内只保持在 120 kmph 然后它开始再次获得速度，但没有达到 170 的 kmph，正如我之前所曾见。。。驾驶回程时始终没有问题，甚至当我再次在完整的节流大部分时间。。。来回程我是该车辆的唯一乘员，白天驾驶及直线路约 50 公里长。。。

In this paper, those teleseismic records with clear P waveforms are chosen to carry out receiver function analysis and modeling. A simple crustal structure model beneath the station is obtained, in which the Moho depth is 28 km. On the top of the upper crust is a 2 kmthick low velocity layer with a shear wave velocity of only 23 km/s. The shear wave velocity increases gradually with depth to 38 km/s in the lower crust.

The results showed that the differences of spatial changes between cultivated land and population in Shaanxi Province are significant. However, the change distribution pattern is basically identical. There is little relative change in southern Shaanxi, while it is volatile in northern Shaanxi and central Shaanxi plain. The cultivated land gravity moves 11. 67 km to northeast during the past 52 years, and the population gravity moves 17.35 km to northeast. The whole trends of them are alike and the distance between two canters of gravity pushes 6.29 km close.

结果显示，陕西省耕地和人口各自空间变化区域差异显著，但变化分布格局大致相同，陕南地区相对变化较小，陕北地区和关中地区中部部分区域相对变化较大。52年来耕地分布重心向东北方向移动11.67 km，人口分布重心向东北方向移动17.35 km，两者整体走势相似，两重心之间的距离推近了6.29 km。
