The pore capacity is becoming smaller with increasingthe vitrinite content. 2. Micro-porosity is dominated in the total pore capacity, which takes more than50%. There is not relationship among pore capacity and specific surface with otherfactors such as Maceral and R0, which shows that the distribution and shapes of poreare not influenced by the composition of the coal. 3. The pore is opened for the coal of Ordos Basin, the order is from durain to clarainthen samples to vitrain. Others are belong to half-opened and thin throat. 4. The adsorption content of gas is increasing with the higher pressure, and the freegas content is decreasing;The adsorption content of gas is decreasing with thehigher temp, and the free gas content is increasing;The adsorption content of gas isincreasing with higher vitrinite content for the kennel coal when temp.

总空隙主要由小孔孔容构成，小孔孔容占了50%以上；镜质组含量和惰性组含量等物质以及镜煤反射率均与孔容、比表面未表现出明显的相关性，说明孔隙分布特征不受物质组成的影响 3、鄂尔多斯地区的空隙呈现开放状态为主，空隙开放的次序为暗煤-亮煤-煤样-镜煤，其他盆地则为半封闭和细瓶颈空隙 4、随压力增加，煤对气体的吸附量增加，煤中所含游离气的量随之减小；随温度增加，煤对气体的吸附量减小，而煤中所含游离气的量随之增加；在相同的温压条件下，同是长焰煤的样品，吸附量在孔容中所占的比例随镜质组含量增加而增加。

It was showed through field trials and pot trials that the content of Zn, Cu and Mn in cole was relational to the total content and bio-available content of that in soils respectively, and the content of As was relational to the total content and bio-available content of As in soils indistinctively, and the content of Cd, Ni, Pb and Cr in cole was under the measure limit.

The principle component analysis showed that head rice ratio, amylose content, chalkiness ratio, gelatination consistency and protein content were most quality traits in low amylase content (5-15%), and head rice ratio, amylose content and chalkiness ratio were most quality traits in low amylase content (5-15%). Correlation of amylose content and 8 agronomic traits showed that: if single plant of low amylase was selected, its'agronomic traits would be affected in negative. Tassel time of low amylose content in 3 combinations was early in their tassel time, and it was important time to select it.

通过主成分分析，可以把整精米率、直链淀淀粉含量、垩白米率、胶稠度和蛋白质作为F2代选择低直链淀粉含量(5-15%)单株的主要品质性状，把整精米率、直链淀淀粉含量和垩白米率作为F3代选择低直链淀粉含量(5-15%)单株的主要品质性状，从而提高选择效率。3个组合类型中，选择低直链淀粉含量较低的单株时，其农艺性状会受到负面影响。3个组合类型低直链淀粉含量单株的抽穗日期都是在每个组合的抽穗早期，因此这是选择低直链淀粉含量单株的重点时期。

Study result suggest: The change of stock in RFCCU directly affect gasoline content. Gasoline content can be reduced through increasing the equilibrium activity of catalyst, controlling reaction level, increasing recirculating rate of gasoline and stability of gasoline level. Conclusions drawn from experiment is that optimization of operating condition has great effect on lowering olefine content of gasoline which can be reduced from 60% to 50%.Reducing reaction temperature is useful for lowering olefine content of gasoline, when the reaction temperature is raised, thermal cracking rate is higher than catalytic cracking rate, so that olefine content is increased. Raising catalyst-to-oil ratio is good for lowering olefine content. With conversion rate increased, the yield of LPG and coke is raised, the yield of gasoline is increased firstly and then decreased slightly, hydrogen transfer index is increased, so the olefine content is decreased.
