From the industry to observe,the author discovers that the regional gap of the secondary industry was the primary contributor,but the rate of was descending.The third industry was becoming the important contributor.The industry structure adjusting and the agglomeration of the third industry and the secondary industry are the primary reason of the forming of the disparity of between the east and the rest areas.In the 1978 to 2005,the absolute convergence of economic growth didn't occur,the other way round,the club convergence of economic growth occurred in the east and in the middle.The speed of the economic growth in the east was higher about 1 centigrade than the middle and the developing west,and was higher about 2 centigrade than the west.

从以省区为单元的中国地区经济发展差距形成的产业构成来看，第二产业的地区差距长期以来都是中国地区经济发展差距的主要贡献者，居主导地位：但是随着第三产业产值比重的提高和第三产业地理集聚的非均衡性扩大(1990年以后)，第三产业的地区差距正逐渐演变为以省区为单元的中国地区经济发展差距形成的主要贡献者。1978-2005年期间，中国地区经济增长并没有出现绝对收敛趋势，而是表现为东中部地区内部的"俱乐部"收敛。1978-2005年东部地区经济增长速度比中西部地区更快，东部地区平均经济增长速度比中部地区高1个百分点左右，比西部地区高接近2个百分点，地区间经济增长速度存在显著的差异。

A large range of IRZ and intense fluctuating velocity area around the boundary of IRZ is measured and thought to be important to keep the excellent ignition and combustion characters of the new kind swirl burner. Together with temperature trace method, different structure and operation parameter of the burner are studied in this paper about their effects on turbulent and mixing characters of swirling jet. The structure variation includes different blade angle, use of central gear shape baffle, variable outer length and angle of lean primary air outlet, use of wedge outlet of lean primary air.

采用上述两种测量方法并结合热质比拟温度示踪的方法，本文对径向浓淡旋流煤粉燃烧器喷口结构和气流流动参数的变化对旋流流场的流动、混合、湍流脉动特性的影响进行了深入研究，研究了旋流叶片倾角大小、中心齿型扩锥、淡一次风扩口外伸长度和扩角的变化、淡一次风楔形扩口、直流二次风扩口角度的变化对出口旋转射流流动特性的影响，研究了一次风率和旋流二次风率运行参数变化的影响规律。

If your sight tube has cross hairs, align the primary's center spot with them; otherwise, center the outer edge of the primary within the sight tube.

如果你的sight tube有"十字丝"的话，把主镜的中央点对准它；如果没有的话，把主镜的反射像的外周调到目镜筒中央。

The first stage was actually the primary purification process, in which most of inorganic ammonium and some total ammine can be removed along with the primary purification process, the second stage was liquid phase oxidation method by sodium hypochlorite, in which inorganic ammonium and total ammine can be further removed.

一段除铵为原有的尾盐一次精制工艺。研究发现，在一次精制的同时，可以除去尾盐中的大部分无机铵及部分总胺，二段除铵采用次氯酸钠液相氧化法，以进一步除去尾盐中无机铵及总胺。
