在高空

A new accurate exterior trajectory model was studied based on the formertrajectory model considering eccentricity of acceleration of gravity etc.

本文在已有弹道数学模型的基础上，研究了地球为椭球体时重力偏心，全面考虑了重力偏心及以往在射程和弹道高不大时忽略的"小量"，建立了高空远程弹箭的较精确弹道数学模型。

Further, we investigated the possible impact of SDP on ENSO event in interannual scale by researching the anomalous characteristics of sea temperature, wind, convergence and divergence, total cloud amount, radiation and so on. The results showed that the influence of SDP on ENSO involve not only the process of positive and negative air-sea feedback, but also the interaction between atmospheric circulation over tropical and subtropical, specially the eastward propagation of anomalous zonal wind from the equatorial Indian Ocean to the Pacific Ocean. Otherwise, it also relates, to some extent, to the transition of large-scale climatic mean flow over the Indian Ocean and Pacific Ocean.

进一步，本文通过分析SDP事件前后期海温、高低层风、低层辐合辐散、高空云量和辐射等的变化特征研究了南印度洋偶极型海温异常在ENSO事件中的作用，结果表明：SDP在ENSO事件中的作用不仅涉及海气相互作用的正负反馈过程，还与热带和副热带大气环流之间的相互作用有关，特别是与东南印度洋海温变化所引起的异常纬向风由赤道印度洋向赤道太平洋传播的过程等有十分直接的关系；同时，SDP对ENSO事件的影响在很大程度上还依赖于大尺度平均气流随季节的变换。

Newest arrival of shipment legal copy Hong Kong NewRay brand alloy vehicle mold: B-29"the stratosphere" time the bomber aircraft US World War II\'S classical bomber aircraft model, Boeing the B-29 superfortress is in the entire World War II the most outstanding large bomber, created many bomber aircrafts: The bomb-carrying capacity 9 ton, the range 6,,000 kilometers, can at the myriameter high-altitude cruise, the extremely fast 600 kilometers/hours. The B-29 development was to at that time the aviation science and technology great challenge, it was the first frame completely depends upon the remote control self-protection weapon and the application central fire control system and the crew compartment production configuration bomber aircraft. B-29 is specially uses in World War II to cope with Japanese the weapon, completed the United States Army navigation air force "to let the flames of war well burnt in the enemy territory" the strategic air bombing intention, has destroyed Japan\'s war foundation, has accelerated the Pacific War conclusion.

最新到货的正版香港NewRay品牌合金车模： B-29"同温层"轰炸机美国二战时的经典轰炸机模型，波音 B-29 超级空中堡垒是整个二战中最杰出的重型轰炸机，创下了多个轰炸机之最：载弹量 9 吨、航程 6，000 公里，能在万米高空巡航，极速 600 公里/小时。B-29 的研制是对当时航空科技的重大挑战，它是首架全部依靠遥控自卫系统并应用中央火控系统和全增压乘员舱的生产型轰炸机。B-29 在二战中是专门用于对付日本的战机，很好地完成了美国陆军航空军"让战火在敌国的领土上燃烧"的战略轰炸意图，摧毁了日本的战争基础，加速了太平洋战争的结束。

As a first-time visitor to South Africa , I had no real desire to cross one of the world's most ethnically and scenically diverse countries in an air-conditioned tube at 35,000ft, nor behind a steering wheel in a metal cocoon.

作为第一次来非洲的游客，我即不愿坐在在开着空调的飞机里离地3万5千英尺的高空穿越这个世界上种族和自然环境如此多样性的国家，也不愿坐在方向盘驱动的金属车厢里。

The results showed that, with the increase of reaction temperature, the catalytic deacidifcation and non-catalytic deacidification ability of MgO were basically decreased at lower space velocity and gradually increased at higher space velocity.

结果表明，随着反应温度的升高，MgO的催化脱酸率和非催化脱酸率在较低空速下降低，在较高空速下逐渐增加；MgO的催化脱酸率和非催化脱酸率在335～365 ℃范围内均随空速的增加而降低；在反应过程中降低反应系统的压力有利于MgO的催化脱酸反应。

The flow field construct of meso-β cloud clusters which bring the heavy-hard rainfall in northeast plateau is that the low level cloud cluster is located in the south of converging region, the southern low level influx converged in the cloud cluster and have some affection on the setting up of the rainstorm in the low level. In the middle level, the cloud cluster is lied in near the westerly trough and the southwest airflow ahead of the trough constantly transmits water vapor to the cloud cluster. In the high level, there are a pair of high and low pressure centers around cloud clusters and are obvious divergence airflow, and there is weak ageostrophic high level outflux along pressure force.

产生高原东北部地区大到暴雨天气过程的中—β尺度云团的流场结构特征是：在低层，云团位于辐合区的南部，低层的偏南低空入流在云团内辐合，对大到暴雨的形成有一定的作用；在中层，云团位于西风带低槽附近，槽前的西南气流不断地给云团输送水汽；在高层，云团附近有一对高、低压中心，为明显的辐散气流，沿气压梯度力方向有强度不强的非地转高空出流。

But, as we often see, against some strom, a silence in the heavens, the rack stand still, the bold winds speechless and the orb below as hush as death, anon the dreadful thunder doth rend the region, so, after Pyrrhus' pause, aroused vengeance sets him new a-work; And never did the Cyclops' hammers fall on Mars's armour forged for proof eterne with less remorse than Ryrrhus' bleeding sword now falls on Priam.

目瞪口呆地站在那里，似乎忘记自己的意愿，对面前的事不知所措。一场暴风雨到来之前，常见高空是寂静无声，乌云在静悄悄地潜行，狂风压住自己的声音，大地死一样沉默不语；可是就在这片刻之间，可怕的雷声震裂长空。皮洛斯经过短暂停顿，重新恢复杀人的恶念；落到普里阿摩的身上

The flying fortress has the fine altitude performance and the splendid anti- attack ability, often after suffered the huge fight wound still to be able to continue to fly, in the later period model, has equipped the formidable defensive weapon, all these caused it to win unit's trust and the affection, they believed B-17 could survives in the German armed force fighter aircraft and in the anti-aircraft gun belt of fire, leads their safe return to base.

飞行堡垒具有优良的高空性能与出色的抗打击能力，往往在遭受到巨大的战斗创伤后仍能继续飞行，在后期的型号中，更是装备了强大的防御系统，所有这些使它赢得了机组的信赖与喜爱，他们相信 B-17 能在德军战斗机和高射炮的火网中生存下来，带领他们安全返回基地。

In the early of 1996, lidar systems, respectively used for detecting Rayleigh scattering and Na resonance fluorescence, were successfully designed in Wuhan Institute of Physics and Mathematics. But the lidar system can operate only at one kind of wavelength every time due to lack of laser equipment, so it can detect either the mesosphere of 30～80km or the sodium layer of 80～110km at a time and cant detect both simultaneously.

武汉物理与数学研究所早在1996年就研制成功了瑞利激光雷达和钠共振荧光激光雷达，但有限的设备使得激光雷达系统每次仅能运行在一种激光波长下，每次只能探测30~80km的中层大气或80~110km的高空钠层，而不能同时探测两者，造成了探测数据在空间和时间上的不连续。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
