Different low-spetral models are used to discuss the variations of the equilibrium states, with the results that the multiple features of equilibrium saltes depend heavily on the truncations of the spectra and the low-spectral model has obvious shortcomings in solving non-linear equations, suggesting that one has to be very careful to employ highly truncated low-sp...

结果显示，平衡态的特性严重地依赖于谱的截断，显示出低谱模式在求解非线性方程中的缺陷，说明用高截断的低谱模式去近似偏微分方程需要特别小心。

Some believe that China has entered a cycle of interest rate increases this year will likely have one or two increases in interest rates, home prices fell Canton, out of which part of the bubble, while the middle and low residential prices will remain stable; think there are experts, together with interest is very low, low prices as a result of Canton, after the rate hike, it is estimated that the future of Canton and the entire Pearl River Delta will experience restorative prices rose, but price increases will slow down the speed of expected growth rate for the five per cent.

有些人认为中国已经进入了一个周期的加息，今年将可能有一个或两个提高利率，房屋价格下跌了广东，其中的部分泡沫，而中低档住宅的价格将保持稳定；认为有专家，连同利息非常低，价格低是由于广东，加息后，据估计，未来的广东及整个珠江三角洲将经历恢复性上涨，但价格上涨将放慢的速度，预计增长率为百分之五。

This article analyzed characteristics and development trend of FCC gasoline in China, introduced the characters and plant effects of OCT-M and FRS FCC gasoline selective hydrodesulfurization process, especially the commercial application effect of the production of States Ⅲ and Ⅳ regulation gasoline. The commercial test results showed that OCT-M and FRS process were mature and credible, and had the characteristics of low pressure, low investment, convenient operation, low H2 consumption and high liquid yield. OCT-M and FRS process could offer refineries optional economical and flexible measure to produce States Ⅲ and Ⅳ regulation clean gasoline.
