增至三倍

But if we start shifting back to non-Bt cotton, I promise you, the tobacco budworm will come back, and we don't want to be making foliar applications for resistant tobacco budworms, in addition to treating tarnished plant bugs.

像牧草盲蝽一样，叶螨对用来控制它们的杀虫剂正在产生抗性。过去15年以来，我们已经基本上翻倍了百治磷的使用率，乙酰甲胺磷的使用率则增至三倍。

Within ten months of Mr Ahmadinejad's election, he reckons, the value of civil contracts awarded to the Guards, many of them without going to competitive tender, had trebled from $4 billion to $12 billion.

他表示，在艾哈迈迪内贾德先生就任总统的十个月里，民事合同没有通过竞争投标直接授予了革命护卫军，所创造的价值从40亿美元增至120亿美元—番了三倍！

Evie climbed 46 places in five years to 15th place last year and Leona tripled in popularity, perhaps after The X Factor winner Leona Lewis.

伊薇在五年中爬升了46名，去年到了第15位。利昂娜的知名度增至三倍，可能和"未知因素"赢家利昂娜路易斯有关。

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。

It is understood that the melamine incident broke out, three in Beijing dairy market sales surge up to 2-3 times the original.
