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。

受检测手段所限在含金黄铁矿、白钨矿、石英等矿物中未发现独立金颗粒，所以我们倾向于寨上金矿次显微金呈微包裹体形式存在于载金矿物中或呈类质同象替代的原子形式存在。

The substrate concentration was not the principal factor for poor grain plumpness of the inferior grains.

同化物基质浓度不是弱势粒充实差的主要限制因子。

The basalt is belong island arc tholeiite and series of the calc-alkaline,and have character of island arc in rare earth element and trace element.

The properties of several rhodopsin sequences were analyzed by comparing withα2A-adrenergic receptor, and a great similarity was found between bovine rhodopsin andα2A-adrenergic receptor. Therefore transmembrane helices ofα2A-adrenergic receptor were constructed homologically based on the bovine rhodopsin.In the newly constructed structure, a 0.090 nm3 active-site, which was enclosed by several reported active residues, was found.

通过对比多个与α2A-肾上腺素受体同属G-蛋白偶联受体的视紫红质蛋白序列，选择以相似性最大的牛视紫红质蛋白为模板，同源模建了α2A-肾上腺素受体的跨膜结构，并在结构中找到了体积为0.090 nm3，已被报导的活性残基包围的活性位点。

In different treatments there were significant differences in male sterility among INACs, of which I TA showed the highest rate of sterility and the best sterility stability under different conditions; meanwhile, altering nucleo cytoplasmic relationship by substitutional backcrosses could modify and improve male sterility of CMS lines.

结果表明，同核异质不育系不育度在年份间、播期间、实生稻与再生稻间差异极显著，不同细胞质不育系间差异显著，其中I特A在各种处理条件下均表现出最高的不育度和最好的不育稳定性。通过回交核置换技术培育新核质关系的同核异质不育系，可达到修饰改良育性的目的。

The amplified fragment was inserted into pRSET-A to generate the first double repeat of the precursor gene. By utilizing a pair of isocaudamer BamH I and Bgl II sites, and another downstream Hind III site of plasmid pRSET-A, following a series of simple double digestions and ligation of the resulted products, a series of repeat (3, 4 and 6) precursor peptide fragment genes were derived.
