半年

I meditated where my time was cost in the first half year:amorism,that's must;play games,that can be decreased;work,there are some times which can be used to study beside official business.

反思自己半年的时间都用哪儿去了，谈恋爱嘛，时间是应该花的，游戏嘛，时间是应该少花的，工作嘛，除了正事，有些时间也是可以用来学习的。

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。

Methods From October 2004 to 2007, we used this flap in 5 patients (1 for antecubital fossa, two for axillary fossa and two for popliteal fossa). The efficacy and versatility of this flap was studied. The time between burn and our reconstructive operation was more than 6 months.

2004年10月～2007年初，利用双蒂瘢痕组织皮瓣共治疗了5例关节部位瘢痕组织挛缩畸形的患者，1例为肘关节，2例为腋窝，2例为膝关节，手术均在伤后半年以上进行。

There'sno way they've even got an internal date that's more specific than aquarter or half year, since the time required for game development andbeta testing varies so much from game to game.

而更重要的是他们不可能把测试和发售的时间定死在半年之内，因为测试和改进所需要的时间经常会变动。

One of the most harrowing stories concerns a Syrian-born Canadian, Maher Arar, who was arrested by US authorities in late 2002 during a stopover in New York, on suspicion of terrorist activities.

这其中最悲惨的一个名叫Maher Arar的叙利亚出生的加拿大人，他因为被怀疑参与恐怖活丢，在2002年下半年在纽约转车时被美国逮了去。

These roles should be reinforced during regular training exercises, such as a mock code, quarterly or biannually.

这种角色应该在每季度或每半年一次的模拟训练之类的惯例训练中得以强化。

Fiona : Can we change our payment plan, say to monthly or biannually?

费欧娜︰我们能不能改变付费方式，例如改成月付或半年付一次？

B: stockholders meetings are held biannually.

股东大会每半年召开一次。

Through the national and local sentinel systems, impact indicators (HIV prevalence among target groups) will be measured and reported biannually.

通过国家和地方哨点监测系统，每半年一次衡量和汇报影响指标（目标人群中的HIV现患率）。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
