The basis function of the coinjection of Nitrogen and steam is increasing the displacement volume and supply the displacement energy on the basis of Nitrogen, the result of the numerical simulation showed that, after the coinjection of Nitrogen and steam (the optional aqueous Nitrogen ratio was 1: 20～1: 50), the theamal readius increased from 30m to 55m more or less, the recovery ratio increased by 5～10％. The production effect of the high cycles steam stimulation will be improved and the pattern infill will be avoided and the economic results will be improved. 4. The poor result of steamflood is another problem. On the basis of the analysis of the foamer mechanism in the propayation, movement and stabilization, this paper showed that the main meachanism of the increasing recovery of the Nitrogen foam and steamflood was the increasing displacement factor and oil displacement efficiency.

三针对蒸汽吞吐加热半径有限（一般30m左右）而蒸汽吞吐轮次已高达5轮以上的具体情况，将氮气与蒸汽混合（套管环空中注氮气，油管中注蒸汽）进行吞吐可增加加热半径1～2倍以上；在对原油流变性研究基础上，对氮气蒸汽原油体系状态进行了分析，指出了氮气在油藏中基本上是以气相方式存在；热氮混合吞吐的基本作用为扩大波及体积和提供驱油能量；在此基础上所进行的热氮混注数值模拟研究表明：蒸汽中加入氮气后（最佳汽氮比为1：20～1：50），加热半径从30m增至55m左右，采收率可提高5～10％以上，大大改善了高轮次蒸汽吞吐的生产效果，可避免大规模井网加密，提高了经济效益。

In this paper, we investigate some interesting models of dark energy, especially the brane scenario, in which our four dimensional universe is embedded in a higher dimensional spacetime where the gravitation can propagate in.

And Rizpah, the daughter of Aiah, took haircloth, placing it on the rock as a bed for herself, from the start of the grain-cutting till rain came down on them from heaven; and she did not let the birds of the air come near them by day, or the beasts of the field by night.

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。

The wind sang in the taut weather-rigging, and blustered around Bush's ears as he stood on the starboard side of the quarterdeck, balancing to the roll as the roaring wind sent one massive grey wave after another hurrying at the ship; the starboard bow received the wave first, beginning a leisurely climb, heaving the bowsprit up towards the sky, but before the pitch was in any way completed the ship began her roll, heaving slowly over, slowly, slowly, while the bowsprit rose still more steeply.

布什站在右舷后甲板，在风浪中努力保持着平衡。一波波的灰色巨浪扑来，右舷的船首最先被浪冲到，缓缓爬升，将船首斜桅举向了空中；然后船身开始摇晃，慢慢的抬升着，船首斜桅的角度更高了；终于船身摇晃着越过了巨浪，船首腾在半空，伴随着大量的泡沫往下直坠；船首斜桅开始下指，船身则笨重的达到了短暂的平衡；接下来整个船身携着泡沫被大海推到风中，船尾被浪峰抬高；最后船头又回到水中。

A technician straps legendary test pilot Scott Crossfield into the cockpit of the X-15 rocket plane before an early test flight.
