A mathematical model of airlift-loop reactor was developed with the two-fluid model and the theory of two-phase flow.

气升式环流反应器ALR具有结构简单、操作方便、流型规整、特别是不需要机械搅拌就能得到良好混合效果和较高传质系数的优点，广泛地应用于生物、环境及化学工业[1]。

It involves the use of rooms with specially designed air handling, the existence of airlocks and/or sterilisers for the exit of materials and secure operating procedures.

二级封闭：防止生物剂进入外部环境或其他工作区的封闭系统，其涉及采用特殊空气处理的房间，离开该区域物料的气闸和/或灭菌柜以及安全操作规程。

In this article the mechanism, synthesis process , application and development of the synthetic technology of nicotinic acid are introduced.

综述了烟酸的作用机理、合成工艺、应用及研究进展，从合成方法上看，一般分为试剂氧化法、氨氧化法、气相氧化法、电化学氧化法、生物氧化法和吡啶羟基化法等。

The samples from the CallovianOxfordian carbonate reef limestone reservoirs in the Amu Darya Right Bank Block are selected to test rock physical parameters by using the MTS system. Samples saturated with gas and water are tested separately under the same experimental conditions. The test results show that seismic responses are significantly different from samples saturated with different fluids. Further analysis shows that the Lame constant parameter is relatively sensitive to gas.

根据土库曼斯坦阿姆河右岸区块油气勘探需要，选取该区卡洛夫-牛津阶碳酸盐岩生物礁储层的石灰岩样品，利用MTS系统进行了岩石物理参数实验测试，通过相同测试条件下饱气和饱水岩样的测试分析，发现岩样含不同流体时地震响应特征有着明显的差异；进一步的分析结果表明：拉梅常数等参数对含气性较为敏感。
