大孔隙

When pH is litmusless, the purification efficiency is the largest. The unhomogeneity of liquid flow results in the uneven biofilm growth. The flow resistance after start-up is significantly larger than that before start-up, whichprovides a method to monitor the biofilm growth.3、The packed bed is simplified to a series of straight capillary tubes covered by the biofilm. The two-phase flow and mass transport, biochemical reaction kinetics, and the limitation of oxygen are taken account of in this model. The results of model are basically in agreement with the experimental data.

通过观察还发现，由于液体分布不均，生物膜在滴滤塔内生长分布不均，并且挂膜后，滴滤塔的孔隙率减小，两相流动阻力比空塔时的大，可采用流动阻力的变化作为判断挂膜成功与否判据。3、首次将多孔填料塔简化成多个竖直毛细管并行排列构成的填料，应用两相流理论，结合生化反应动力学，并考虑氧的限制，建立了一个生物膜滴滤塔降解废气的毛细管模型，其结果与实验数据吻合得较好。

Antibacterial deodorizes : The bamboo coal's charcoal structure is compact, the proportion is big, the holes are many, the mineral substance content is rich, therefore has the very strong adsorption resolution capability, to the air sulfide, the nitride, the methyl alcohol, the benzene, the phenol, the chloroform and so on organic pollutant or the harmful chemical substance, can display the outstanding absorption and disappear the smelly function.

六：抗菌除臭：竹炭的炭质结构非常致密、比重大、孔隙多、矿物质含量丰富，因此具有很强的吸附分解能力，对空气中的硫化物、氮化物、甲醇、苯、酚、三氯甲烷等有机污染物或有害化学物质，均能发挥优异的吸收和消臭功能。

Under experimental results of wax deposition and phase change, the mechanical characteristics of fluids flowing through porous media and the relevant physicochemical problem were all summed up as solving the gas-liquid-solid coupling mathematical model. After considering the phase change action between condensate gas and condensate liquid, wax deposition interlarded with interfacial drag force and capillary pressure engendered in the process of phase change. Numerical simulation results proved that the flow resistance increased and the production output decreased owing to wax deposition.

在蜡沉积变相态渗流实验和渗流数学模型的研究基础上，引入蜡沉积数学模型、考虑毛管力和表面张力的相对渗透率模型等，建立了相应的多孔介质中气－液－固变相态多相流－固耦合渗流数学模型，数值模拟结果表明，蜡沉积可使都分区域孔隙减少，流动阻力增大，不考虑蜡沉积会对产量预测明显偏大，蜡沉积可使产量下降。

The surface state and electrochemistry properly platinum-plated on open-cell foamed titanium electrode was investigated and he compared with IrTi anode and platinum-plated titanium toil cathode. The results show that open-cell foamed titanium can uniformly coat with excellent bonding strength platinum-plated, thickness coating 2 μm. The cathode release hydrogen voltage of platinum-plated on open-cell loamed titanium electrode is fall. The anode release oxygen voltage of platinum-plated on open-cell foamed titanium electrode is higher than Irli anode in high current.
