Through researching the mechanism of biological nitrification and denitrification and actual project application of the technology and related literature materials, the obtained results are as follows:(1) Anoxybiosis is effective to the removal of COD; after the anoxic process, BOD/COD of the outflow increases, it shows that the degradation ability of wastewater is improved; anoxybiosis is insensitive when shock loading of inflow wastewater varies greatly;(2) It is demonstrated by the operation of inoculation and cultivating that biofilm takes two weeks to succeed in cultivating on packings and the removal ratios of NH3-N and COD get 50% and 70% respectively, when gas-water ratio is 6:1, HRT is 7.3 hour, water temperature is above 15°C;(3) It is demonstrated that gas-water ratio, hydraulic loading, HRT, temperature, pH etc are important factors which influence the removal effect of pollutants, when the gas-water ratio is 6:1, hydraulic loading is about 0.38kgNH3-N/m~3.d, water temperature ranges from 15°C to 27°C, pH ranges from 7.5 to 8.0, the BIOFOR removal effect of pollutants is the best;(4) The operation indicated that, this technology has strong ability of nitrification and denitrification; it has extremely vital significance for reducing the water body eutrophication;(5) It is confirmed the feasibility and the usability of preanoxic-BIOFOR process to treat L-lactic acid production wastewater. The experiment indicated that the treatment effect of this technology is very good and also shows that the technology has many advantages, such as small volume, high treatment efficiency, good effluent quality and strong endurance to load variation, this technology is a new and economical wastewater treatment process.

通过对生物脱氮机理的研究和该组合技术的实际工程应用，并结合有关文献资料，取得如下结论：(1)预缺氧池对L-乳酸生产废水中的COD去除具有一定的效果；废水中难降解的高分子物质经过缺氧工段分解为易于氧化降解的物质，浮状有机物在水解菌的作用下，将不溶性有机物水解为溶解性物质；预缺氧池具有较强的抗冲击负荷能力；(2)BIOFOR接种挂膜过程表明：HRT为7.3h、气水比为6：1、水温保持在15℃以上，经过半个月生物膜即以形成，NH_3-N和COD的去除率分别达到50％和70％左右；(3)研究表明：气水比、水力负荷、HRT、温度、pH等是影响污染物去除效率的重要因素，在气水比为6：1，NH_3-N容积负荷为0.38kgNH_3-N／m~3·d，温度在15℃-27℃，pH在7.5-8.0之间的条件下，BIOFOR对污染物的去除效率达到最佳；(4)运行表明，该组合技术具有较强的脱氮能力，对于减少水体富营养化具有十分重要的意义；(5)经过半年多实际工程的现场调试与运行，验证了利用预缺氧—BIOFOR组合工艺处理L—乳酸生产废水的可行性和实用性，得出该组合技术具有占地面积小，处理效果好，运行费用省，耐冲击负荷能力强等优点，是一项新型、经济的污水处理技术。

Another version from A catechism of familar things: It is supposed to have originated from the discovery of a dead tortoise, the flesh of which had dried and wasted, so that nothing was left within in shell but sinews and cartilages:these,tightened and contracted, on account of their dryness,were rendered one ,Mercury of Apollo, they affirm, in walking along happening to strike this foot against the tortoise, was greatly pleased with the sound it Diane Touliatos-Miliotis: the other part of the Chelys-lyre include a "donax", which was a cana of reed that possibly functioned as a bridge or brace of the arms.

Essential hypertension caused by neurovascular compression of the left ventrolateral medulla was associated with malbalance of vasomotor center in the dorsal medulla. The possible pathogenesis was the following:① An irritation of the left RVLM by pulsatile compression of an ectatic vessel would increase activity of central sympathetic neuron.② Neurovascular compression at the REZ of the cranial nerves Ⅸ and Ⅹ decreased excitation of parasympathetic nerve.③ Decreased sensitivity of afferent inputs to neuron of nucleus tractus solitarii in the sensory area lead to hyperactivity of central sympathetic nervous system due to pulsatile compression of the left RVLM.④ Neurocompression of the left RVLM and REZ in the left cranial nerves Ⅸ and Ⅹ lead to an overactivity of central renin angiotensin system.

3，结论：左侧延髓腹外侧Ⅸ、Ⅹ颅神经REZ动脉血管压迫所导致的高血压的发生与左侧延髓血管运动中枢对血压的调节失衡有关，其可能机制是：①左侧RVLM在搏动性血管压迫刺激下，中枢交感神经元活性增高；②左侧Ⅸ、Ⅹ颅神经REZ受压导致副交感神经兴奋性降低；③感受区孤束核神经元接受迷走神经传入冲动的敏感性减低，导致中枢交感神经活性增高；④左侧RVLM及Ⅸ、Ⅹ颅神经REZ受压引起中枢RAS活性增加。
