Aerobe bacteria overgrowth and decreased lactobacillus of the small intestine will strengthen the pathogenicity of gut flora and disturb the absorption of nutrient, resulting in many symptoms related with alcohol. And these changes are result from complex factors not direct effect of acohol.

结论长期饮酒后小肠需氧菌过长、乳酸杆菌减少，增强了肠道细菌的致病性，影响肠腔营养物质的吸收，导致酒精相关的肠道病变的发生，且这种改变是诸多因素共同造成的而非酒精直接作用的结果。

在室内模拟的条件下显示，准好氧填埋场垃圾渗滤液的COD自然衰减至国家一级排放标准(100mg／L)仅需2～3年，而氨氮只需1年左右即可达到相应的国家一级排放标准(15 mg／L)。

To determine the content of deoxidant timely and precisely is urgently need in the operation of boilers.

锅炉给水除氧剂含量的多少直接影响除氧效果的好坏，为此需及时准确地测定给水中除氧剂的含量。

Mixed saliva and pooled plaque samples from the smooth surfaces of teeth were collected for microbiologic analysis before administration (baseline~ day 0).. during treatment (days 7.. 14 and 21) and after withdrawal of the agents (days 28~ 42 and 56) and plaque index were recorded. Microbial cultivation were performed by serially diluting the samples with PBS solution and cultivating the aiquots on Mitis Salivarius Agar and MS supplemented with bacitracin for Oral streptococci and Mutans streptococci respectively. The plates were incubated at 37~C under microaerophilic condition(90%N2,10%CO.,) for 48 hot:rs. The number of colony-forming unit per plate was counted and the percentage of Mutans Streptococci per Oral streptococci in dental plaque were determined.

使用前、使用中1、2、3周及停止使用后1、3、5周分别记录菌斑指数并收集唾液及光滑面集合菌斑样本，应用MS及MSB培养基微需氧环境培养检测唾液和菌斑中口腔链球菌属细菌及变形链球菌的菌落形成数，分析各组使用药物前后唾液中变形链球菌的改变及菌斑中变形链球菌在口腔链球菌属细菌中百分比的变化以及变化的延续性。

The nitrogen cycle provides essential nutrients to the biosphere, but its antiquity in modern form is unclear.

据2月20日的《科学》杂志报道说，在一个有25亿年历史的澳大利亚页岩中所测到的氮和碳同位素也许可以捕捉到现代需氧氮素循环的最初日子，该循环是由远古的微生物活动所驱动的。

Under anaerobic condition, bacteria could respire with diverse noxious substances as terminal electronic acceptor. Electrons were transferred in the electron transport chain from electron donor to electron acceptor and formed trans-member proton concentration gradient, and were furthermore conserved into energy for metabolism.

在厌氧条件下，细菌利用环境中多种有毒物质作为呼吸链末端电子受体进行厌氧呼吸，在有毒物质被还原甚至降解的同时实现电子在呼吸链上的传递，形成跨膜的质子浓度电势梯度，进而转化为其生长代谢所需的能量。

An oxygen-bubble and white-light speckle velocimetry method is presented.Instead ofpulsed laser and commonly used particle,a sheet like-bubble mass generated from anade wire byeletrolysing water is used as particle tracer,a white light flash set controlled by digital time delaycircuit is used as double pulsed light source,and 2-D velocity distribution in a sectional planewithin flow field can be obtained without using light sheet technique.

提出了一种氧气泡粒子白光散斑测速技术，与以往散斑测速方法不同的是，采用电解水时电解阳极丝上产生的氧气泡做为流场示踪粒子，用两个闪光时间间隔由数字延时电路控制的普通闪光灯做为散斑底片拍摄时的双脉冲光源，并且勿需片光技术，即可获得流场内部一个截面上的二维速度分布。

It is considered that the hydrolysis of phase 5 or phase 3 in water can be themain cause for the poor water resistance,which can be improved by the addition of phosphonic acid or p...

讨论了氯氧镁水泥耐水性的评价方法，并对今后的研究提出了几个尚需深入的方面。

The test results showed that when the cycle water flow was 65m^3/h and the oxygen flow was 1, 2,……, 10L/min, the relationship between the dissolved oxygen and oxygen flow in the water was y=0.1009χ^2+0.0594χ+5.9588 (r=0.9927). According to the mass balance principle, the maximum oxygen utilization rate of oxygen cone was calculated at 84.56%. Under the condition of the maximum oxygen utilization rate of oxygen cone, according to the rate of Nile tilapia oxygen consumption, the number of oxygen cone was projected in industrialized fish farming system. It provided the basis for oxygen supply system design in industrialized fish farming system.

结果表明，在循环水流量为65 立方公尺/h，水温24.5℃，氧气流量为0， 1， 2，……，10 L/min的条件下，溶氧与氧气流量回归方程为y=0.1009χ^2+0.059 4χ+5.958 8(r=0.9927)；根据物料平衡原理，推算出氧气锥的最大氧气利用率为84.56%；在最大氧气利用率的条件下，依照尼罗罗非鱼的耗氧率计算模式，推算出工厂化养鱼系统需配置氧气锥的台数。

We demonstrate that not only have lamnids and tunas converged to a much greater extent than previously known, but they have also developed morphological and functional adaptations in their locomotor systems that are unlike virtually all other fishes.

研究发现，在金枪鱼和尖吻鲭鲨这两种亲缘关系很远的鱼类之间存在一个演化上的汇聚点，这个汇聚点绝不是表面上的，而是达到了需氧肌肉的组织和推进运动的机械基础这样的深度。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
