结果发现负压隔离病房微粒去除效果之最佳化参数组合为：中型体积(36.93 m3)、每小时换气12次(12 ACH)、负压值5 Pa，在靠近排气口头部位置进行释放之实验条件。

And the optimize of underbalance drilling fluid is gone on in view of stratum and reservoir geologic characteristic in DaQing oil field, finally a suit of reverse emulsion drilling fluid system fitting DaQing oil field underbalance drilling is established, and it is successfully used and verified in erbalance drilling construction work, the effect is very ideal. Additional the well control technique and commensurable auxiliary technique of underbalance drilling are also systematically analysed, a suit of auxiliary technique and well control scheme of underbalance drilling fitting DaQing oil field zone of negative pressure is established.

本文重点对欠平衡钻井负压值的影响因素及确定方法进行了研究；并针对大庆油田地层及油藏地质特征进行了欠平衡钻井钻井液体系的优选，最终确定了一套适合大庆油田欠平衡钻井的水包油钻井液体系，并成功地在欠平衡钻井施工中得到应用和验证，效果十分理想；另外，本文对欠平衡钻井的井控技术及相应的配套技术也作了系统的分析，确立了一套适合大庆油田地层特点的欠平衡钻井工艺技术配套措施及适合大庆油田地层负压特点的钻井井控技术方案。

The application of the lattice Boltzmann method in unsteady open channel flows was studied in detail in the paper. An existing lattice BGK model was mended; For the problem of negative local equilibrium and evolutionary distribution, we proposed a lattice Boltzmann model based on cell-population equilibrium, which is a direct non-negative approximation to the continuous Maxwell distribution. The model reduces the transport and collision, two basic evolution steps in the LB model, to transport of the non-equilibrium distribution.

本文系统的研究了格子Boltzmann 方法在明渠非恒定流中的应用问题，改进了一个现有的LB 模型，数值实验表明此改进是有效的；在平衡态分布函数及分布函数的非负性问题上，作者提出了一个基于单元均衡的格子Boltzmann 模型，通过直接对Maxwell 分布函数的离散化实现对速度分布函数的非负离散，这种方法将传统模型演化过程中的碰撞和输运两个步骤直接表现为粒子的输运。
