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。

Therefore the dispersion curves obtained in the field are primarily consisted of the first mode. For a heterogeneous elastic solid consisting of three homogeneous layers whose interlayer has low velocity, the phase velocity V〓 of the first mode will also close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, but V〓 of the first mode will close up to the shear wave velocity of the interlayer when f→∞, and there is a cut-off frequency at high frequency region for the first mode and V〓 close up to the compressional velocity of interlayer when interlayer is liquid.
当三层固体介质中存在软夹层时,若f→OHz,则其基阶模式的相速度V〓→V〓(V〓为最底层介质的瑞利波速度);若f→∞,其基阶模式V〓→V〓(V〓为中间层介质的横波速度);若三层介质中存在液体夹层,当f→OHz时,基阶模式V〓→V〓,而基阶模式在高频段存在一个截止频率,截止频率处的瑞利波速度V〓→V〓;由此可判定,野外实测的相速度频散曲线不仅有基阶导波模式,同时还应有高阶导波模式波的存在,接收信号中存在模式间的跳跃,因此频散曲线会产生"之"字形现象。

The research of both theories and practices of gridding in the dissertation shows that: Linear interpolation based on triangulation is simple computationally and fast, but its gridding results isn't smooth and its precision is low; Multiquardric method is also simple computationally with high precision and good effect, but its gridding is slow because it is based on global calculation; Minimum curvature method is fast with high precision and good effect, but its gridding quickly degrades over areas with sparse data control when grid spacing smaller than the actual grid spacing is used; Ordinary Kriging method is high-precision, but its gridding is slow because of large calculation; Inverse interpolation is a computationally fast, efficient and robust method with high accuracy and perfect effect, and its gridding results of different gridding orientations are basically identical. Inverse interpolation is suitable for thegridding of geophysical irregular data, especially for large-scale geophysical irregular data.

Effects of dry temperature and dry time on properties of heat cured sand and the relationship with binder composition are as follows:sands bonded by binders that are not modified have high strength when dry temperature is high and dry time is long,but their anti-wettability power is poor . Sands bonded by binders that are modified by B but not modified by M can be dried quickly and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M but not modified by B can also be dried quickly to obtain maximum strength,then the strength becomes lower when they are dried continually for more time. and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M as well as by B at the same time can be dried quickly to obtain maximum strength at low temperature and short time. But the anti-wettability of sand mold is best when they are dried at high temperature and long time.
烘干温度和烘干时间对热硬砂性能的影响及其与粘结剂改性的关系是:未经改性剂B和改性剂M改性的粘结剂砂,脱水速度较慢,烘干温度越高,时间越长,则硬化强度也越高,但未经改性的粘结剂热硬砂的抗吸湿性较差;经改性剂B而不经改性剂M改性的粘结剂热硬砂,烘干硬化速度较快,强度也高,但在高湿度下的抗吸湿性不好;经改性剂M改性而不经改性剂B改性的粘结剂热硬砂,烘干时强度先随烘干时间升高至最大值后,继续烘干时强度又出现下降;经改性剂B和经改性剂M共同改性的粘结剂热硬砂能在短时间和较低的烘干温度下就可烘干到最高强度,即烘干脱水的速度较快,但试样的抗吸湿性差,若在更高温度和更长时间下烘干,试样的抗吸湿性得到改善,综合考虑烘干强度和抗吸湿性要求,对于φ30×30mm试样,理想的烘干温度是200℃,烘干时间20分钟。

By regression of experimental data, therules of the linkage between these factors, which will provide a theoretical basis for designing BBP with different scales.3 Using thermal analysis technology and dynamic thermogravimetry, the paper studies combustion kinetic characteristics of 3 types of agricultural crops at different rate of temperature rise, and thus, achieved dynamic parameters of these fuels at different rate of temperature, established dynamic model of straw combustion, which reflects the dynamic process in the fast combustion area.4 Characteristics of straw briquette combustion was experimented, focusing on the impact of straw type, temperature, air supply, and density, diameter, and weight of briquette on the combustion speed, and the following conclusions were drawn:(1) combustion of straw briquette fuel is static permeation diffusion combustion;(2) temperature has a larger impact on the speed of straw briquette combustion than air supply; the higher the combustion temperature is, the faster volatilizable component separates out, and the less steady the combustion is;(3) density of briquette fuel has impact on the speed of volatilizable component separation and therefore the combustion speed;(4) increase of diameter and weight of briquette fuel increases the average combustion speed in the initial stage, and that in the later stages is comparatively steady;(5) the proportion of volatilizable component in straw briquette fuel is high, therefore, the temperature control during combustion under the rational ventilation condition is essential to ensure its safe combustion.5 Using the above-mentioned results of experiments and theoretical analysis, and based on thought of hydraulic driven and bi-direction compression, the hydraulic system and compression parts of the HBP BBP are re-designed in terms of industrialization.

And the pressure drop of liquid-layer is mainly influenced by weir height. With the increasing of weir height, the pressure drop increases. And it is independent of bare tower velocity and plate dimension. The correlation before was corrected as follows:ΔpL=3911Z This paper analyzed the heat transfer coefficient between the outer wall of heat tubes and cooling water. And it was considered that plate geometries、weir height、bare tower velocity and heat flux density would affect the heat transfer coefficient.
