He expresses at the same time, long triangle special develop, but make modelling economy can not last for a long time certainly; The course of study of venture capital investment that bay division develops most has aided a helping hand with respect to the economic transition that is the United States in those days, rich experience helps this one area accelerate transition.

As a result, a weak indirect cell is formed in high latitudes. By the 36th time step, the model atmosphere accomplishes the transition form one-cell circulation to two-cell circulation. There is a momentum source in the upper subtropical region. During the transition, the"polar westerlies jet"gets weakened and vanishes at the end, while the subtropical westerlies jet gets strengthened. At this two-cell stage, the generation and dissipation of westerly angular momentum do not balance each other, and the atmosphere is still at an unstable state with great surplus of angular momentum generation.

随着模式的运行，直接环流加强，地表东风带制造西风角动量加大，上支气流的加强，同样在科氏力的作用下，在副热带地区形成副热带西风急流，同时所谓的&极地西风激流&向赤道靠拢、减弱，最后消失，这时在整个半球形成了靠赤道的直接环流和靠极地一侧的间接环流，两圈环流形成的过程仅仅需要9个小时左右。

Because the original design of our imagination is the direction to the development of market maker in the form of participation in the market, because the Shanghai Gold Exchange is still no clear blueprint for the development of some new out, I expect the Shanghai Gold Exchange, even though he has not been for gold futures, but he still has many talents Potential, he used the original nation's largest cash trading platform that advantage, I suggest he should, as markets like London, the development arm of a road through the market maker in OTC transactions done, so we originally domestic gold investment companies can legally participate in the open market, so we have two domestic gold market coexist, is a futures market, is a spot market, the original investment in gold companies, I think now it is in transition towards services, information of this transition.

因为原来我们设计的想像的发展方向就是以做市商的形式参与这个市场，因为现在上海黄金交易所目前还没有明确的一些新的发展蓝图出来，我预计上海黄金交易所这次尽管他没有争取得到黄金期货，但是他还是有很多优势的，他利用原来国内最大的现货交易平台这个优势，我建议他应该像伦敦市场似的，以发展做市商为一个路子，通过做市商的参与做场外的交易，这样的话我们国内原先黄金投资公司就可以合法公开参与这个市场，这样的话我们国内就有两个黄金市场并存，一个是期货市场，一个是现货市场，对原来的黄金投资公司来说我觉得现在要转型的话应该是朝服务、资讯这块转型。
