The desulfurization experiments of CaO samples with various fractal dimensionswere carried out in the TGA to investigate the influences of fractality on the sulfationreaction, and the evolution of pore structures during the reaction. Under certainsulfation conditions, the calcium conversions of the CaO samples increase with theincrease in fractal dimension when fractal dimension is less than 2.68, and decreaseswhen it is more than 2.68. In the range of the experiment temperatures, the calciumconversion for a sample with a lower fractal dimension increases with the increase inthe temperature, and for a sample with a higher fractal dimension there exist anoptimum temperature at which the sample can reach the highest calcium conversion.

选用具有不同分形结构的CaO试样进行了硫化实验，研究孔结构的分形特性对硫化反应的影响以及硫化过程中分形孔结构的变化特性，实验结果表明，在一定的分形维数范围内，随着分形维数的增加，钙利用率增大，但分形维数超过一定值时(约为2.680)，钙利用率反而降低。

However, agricultural production has the characteristics of large coverage, frequent changes seasonally and regionally, and low benefit in per unit area, therefore, it is unfeasible to get the annual information through ground in situ measurement neither in the aspect of technical issues nor in the aspect of economic sustainability.

This analytical approach shows that, as increasing the wear flat of indenter, the maximum indentation force needed to develop critical plastic zone increases and its corresponding critical penetration depth also increases slightly, Note that the effect of wear flat will affect rock fracture behavior. In addition, regarding the simulation of the effect of doubled-indenters, result shows that two adjacent indenters may interact each other as reaching the transient/critical relative space between indenters of 2~3. It dicpicts that a proper spacing arrangement between indenters may enhance a efficient mechanical cutting due to the less required maximum indentation force and energy dissipation.

由数值模拟之结果得知，当楔尖磨耗增加时，岩材产生脆性破坏之初裂贯切力随之增加，而其对应之临界贯入深度则亦微幅增加，故磨耗效应确会干扰岩材脆性破坏机制之形成；而由双刀效应之模拟，可知两贯切刀楔互制影响之破坏裂缝生、衍行为，当双刀相对刀距为时，岩材之破坏特徵有明显变化，即定义此为临界相对刀距，并探讨其产生脆性破坏所需初裂贯切力之变动范围及应力重叠区，由此得知适当之刀距安排将有助於减少能量之耗损。

The results show that the rate of heating decreases due to the growth of oxidation layer in soaking process when the thermal resistance between gas and slab increases. The quantity of loss of iron scale increases with the increase of the coefficient of air consumption under the condition of certain soaking temperature. When the coefficient of air consumption is certain, the quantity of loss of iron scale increases with the increase of soaking temperature rapidly. The results of numerical simulation is consistent with experimental ones, and the error is very small within the range of soaking temperature in CSP line.

研究结果表明：在加热过程中生成的氧化层增大了换热热阻，使钢坯的加热速度减小；钢坯氧化烧损量随加热速度的增大而减小；当达到同一特定的均热温度时，钢坯氧化烧损量随空气消耗系数的增大近似呈线性递增；当空气消耗系数一定时，钢坯氧化烧损量随均热温度的提高而急剧增加；数值计算结果与实验结果变化趋势一致，并在CSP均热温度范围内较吻合。

Operational Tran conductance lifers and Grounded actorhas become one of the most important methods to implement integrated continuous-time filters. Operational Tran conductance Amplifierscan transfer input voltage into current to output,and control or change output current within large range by an external controlling current of amplifier.
