The results indicate that the high efficiency and stable performance of shortcut nitrogen removal in MBR-PBBR process is attributed to the predominance of functional microbiology Nitrosomonas eutropha during the period of operation,which occupies over 54%of total bacteria.However,large amount of organic carbon can destroy the predominance of N.eutropha,whose proportion decreased to 31%at TOC/N=0.3.The diversity of microbial community in MBR increases along with operating time.

结果发现，生物强化的MBR-PBBR工艺能实现相对稳定和高效的捷径生物脱氮，主要归功于MBR中的功能微生物Nitrosomonas eutropha在运行过程中始终保持优势地位，占全菌数的比例大于54%；然而，当外加有机碳源较高(TOC/N≥0.2)时，可动摇氨氧化菌的优势地位，N.europha占全菌数的比例在TOC/N=0.3时下降至31%。

Some aggregates of the active elements appeared on the oxidic catalyst samples and the aggregates could be re-dispersed by sulfidation. The reduction and sulfidation ability of the regeneration catalysts were increased in low temperature region.

对催化剂氧化态和硫化态的表征结果表明，催化剂在失活—再生过程中，比表面等物理性质有一定的变化，再生催化剂活性组分发生聚集，该聚集体经硫化后可得到重新分散，催化剂的低温还原性和硫化性能增强。

Control factors of VRLAB in manfacturing process were discussed, and the reasons for control the factors were analyzed. The results show that iron in lead should be control in 0.000 7%, oxidizability of lead should be controlled in ±5% require...

通过查阅文献并结合生产实际，对VRLAB生产过程中需要控制的因素加以论述，并论述了控制这些因素的原因，指出铅粉中铁杂质含量宜控制在 0 。0 0 0 7%以内，铅粉的氧化度应控制在要求指标的± 5 %以内，灌酸密度应控制在技术要求的± 0 。0 0 5g/cm3 以内。

F. On the other hand, as the gas with high oxidizability introduced to pre-reduction process, it will give a lower reductibility of iron ore and as the ore come to the final process the burden of the final reduction vessel will be heavier, the refractories of it will be corroded seriously and the campaign-life of it will be shorter.

终还原排出的煤气可以供预还原使用，由于排出煤气温度较高，需要降温才能供预还原炉使用，在此过程中煤气的物理热未被利用，这是目前熔融还原工艺能源消耗普遍大于高炉工艺能源消耗的主要原因；同时排出煤气氧化度较高，影响到矿石的预还原率较低，铁浴终还原的负担较重，终还原炉渣对炉衬的侵蚀严重，影响到铁浴终还原炉的寿命。

The Change of hot strength of iron ore pellets during oxidizing roasting and reduction was researched.

The 400-meters dash belongs to ultimate periodic games and is regarded as a short-distance run which can be divided into 3 periods—the period of acceleration, period of remaining maximum speed and the period of attenuation. The 400-meters dash follows the statistic rules which can be reflected from the following stage: starting the race, accelerating, reaching the maximum speed and gradually attenuating. In fact, it reflects the process that energy is provided. It is a changing process of energy providing—from phosphagen system,glycolysis system to aerobic oxidization system.

400m跑属于极限强度的周期性运动，被视为一项以速度为主的体能类短跑项目，其全程速度的变化一般可分为三个阶段，即加速阶段、最高速度保持阶段和速度衰减阶段。400m跑从起跑加速到获得最大速度后又逐渐降低的统计学规律，实质上反应了能量供应方式从磷酸原系统、糖酵解系统到有氧氧化系统的转变过程。
