查询词典 soot

The loss of the diesel soot and smoke Cha Cha PAHs in the leaching rate of the most important factor is the length of brewing time;PAHs were detected in the loop on the small number of PAHs,5 of the ring PAHs were only in the low level of test,and the experiment detected no PAHs, detected no 6 of the ring,regardless of diesel smoke or soot Cha Cha,the concentration of PAHs has the highest concentration of dihydrogen Acenaphthene;On the influence of the number of brewing tea,the total concentration and the leaching rate of PAHs in the soot and smoke Chai tea are lower than on the influence of the brewing time and temperature.

其中影响煤烟茶和柴烟茶中PAHs浸出率的最主要因素都是冲泡时间的长短；检测出的PAHs都集中在环数较少的PAH，5环的PAHs仅在较少的试验水平中检出，无6环的PAHs检出，无论煤烟还是柴烟茶中PAHs的浓度都以二氢苊的最高；在冲泡次数影响下，煤烟茶、柴烟茶中PAHs的总浓度和总浸出率，比在冲泡时间和温度影响下要低。

The results show that SO2 gas itself does not influence the growth of ZY-1, however, when the SO2 concentration is higher than 50×10^(-6), ZY-1 growth rate and its CO2 fixation rate are all lowered and the pH of the medium is decreased, so measures must be taken to desulphurize or control pH of medium temporality. The presence of NO with concentrations of lower than 300×10^(-6)did not influence the growth of ZY-1 and its CO2 fixation, NO absorbed in the medium is utilized as a nitrogen source. The influence of dissolved soot dust on ZY-1 growth and its CO2 fixation could be ignored once the soot dust in the stack gases was disposed by the original method.

结果表明，烟气中的SO2是以增加培养液中的SO2^(-2)浓度及降低pH的形式来影响ZY-1的生长及其对CO2的固定的，当其浓度大于50×10^(-6)时，需要进行烟气脱硫或控制培养液pH变化来消除其影响；烟气中NO浓度不高于300×10^(-6)时，不影响ZY-1的生长及其对CO2的固定，反而可作为氮源供ZY-1生长用；对经过一般除尘处理的烟气来说，在利用小球藻ZY-1固定CO2时可不考虑溶解性烟尘的影响。

The results from electron micrographic analysis show that soot oxidation is influenced by aggregation and agglomeration of soot particulates, at the same time, the crystallograms show that the previous soot particle is non-crystal carbon, but in the latter conbustion period, a very small amount of crystal soot with unstable lattice at relatively higher flame temperature is formed. The crystallization happens greatly in period of combustion when temperature is relatively lower. The smoke particulates consist of crystal carbon similar to chaoite crystal latice and noncrystal carbon.

碳粒浓度和KL变化曲线表明预混合火焰中碳粒浓度远远小于扩散火焰，其原因在于不均匀的燃油—空气混合气结构在高温缺氧条件下产生大量碳粒，在温度峰值附近碳粒浓度亦达到峰值，其后迅速氧化，当温度低于2000°K时碳粒基本上不氧化，碳粒的电子显微分析表明碳粒的氧化受碳粒的集聚过程的影响，在燃烧初期碳粒是非晶体，碳粒的结晶在燃烧后期和排放过程中大量出现，排放碳烟微粒由晶体和非晶体碳组成。

The results show that the radiative properties of randomly distributed soot aggregates for a given fractal dimension are complex functions of the monomer diameters, the number of monomers in the aggregates,and the refractive index; For a small value of the monomer diameters, the absorption cross section of soot aggregates tends to be relatively constant when the fractal dimension is small but increases rapidly when the fractal dimension exceeds two. However, a monotonical reduction in light absorption with the increase of the fractal dimension is observed for soot aggregates with sufficiently large monomer diameters, number of monomers,and refractive index. The scattering cross section , extinction cross section and single-scattering albedo increase monotonically with the increase of the fractal dimension. Overall, the results for soot aggregates differ profoundly from those calculated for the equivalent spherical particles, and the discrepancies between them will change small with the increase of the fractal dimension.

研究表明，在给定分形维数的情况下，烟尘団簇粒子的辐射特性取决于原始微粒粒径、数量及复折射率；原始微粒较小的団簇粒子，当分形维数较小时，吸收截面变化不明显，但当分形维数大于二时，吸收截面骤然增大，然而，对于具有比较大的原始微粒粒径、数量及复折射率的烟尘団簇粒子，吸收截面随着分形维数的增大而单调递减；随着分形维数的增大，団簇粒子的散射截面、消光截面及单次散射反照率均单调递增；从整体上来讲，団簇粒子的辐射特性与等效球形粒子的辐射特性存在着比较大的差别，并且这种差别随着分形维数的增大而减小。
