The research shows that the development of eco-environment and socio-economy belongs to environment lag-type of coordinated s development kind. From 2001 to 2004, the coordinated development value descended year by year. The sustainable development level shows degressive trend.

分析结果表明：成都市生态环境与社会经济之间属于协调发展类环境滞后型，且2001~2004年协调发展值逐年下降，可持续发展情况呈下降趋势。

First, some critical problems in crystal growth like crystal seeding, Zn dephlegmation, geometrical selection and temperature fields are discussed in theory, and the possible kinds of defects appeared in crystal growth progress and the reasons are carefully researched. To control the concentration of Cd vacancies, a new method by which the Cd vacancies were compensated with excess Cd in the Cd rich starting materials has been developed, and a new kind of two-area tube furnace with good linear temperature distribution was designed.

首先，本文从理论上对坩埚下降法生长碲锌镉单晶体中的成核、Zn分凝、几何淘汰生长与温场等关键性问题进行了讨论，对在生长过程中可能出现的各种缺陷类型和形成原因进行了详细分析，提出了碲锌镉单晶体生长过程中Cd空位缺陷控制原理及方法，并针对坩埚下降法生长特点自行设计了两区域独立加热管式生长炉，获得具有较好线性分布的温场。

The researchers calculated the proportion of desaturation to respiratory eents as the ratio of oxygen desaturation index to apnea-hypopnea index.

研究者将呼吸过程中饱和度下降发生的比例作为血氧饱和度下降指数与呼吸障碍指数的比值。

The reason may be that complex formed by rhodium and halide was difficult to produce the catalytic active species. Therefore halide ion was the poison for the rhodium catalyst in hydroformylation of olefins in ionic liquid. The effect of double long chain cationic surfactant (DCMAB, dicetyl dimethylammonium bromide) on selective hydrogenation of cinnmaldehyde catalyzed with RuCl3·x H2O/TPPTS was studied.

进一步的研究表明在使用有良好反应活性的两种催化剂HRh3 、Rh_2进行催化反应时，向体系中加入含有卤离子的化合物时将使反应活性大大降低，而且随着卤化物加入量的增加，催化剂的活性迅速下降，这是卤离子可能和金属铑作用使它难于生成催化活性物种，进一步证明卤素离子是引起催化剂活性下降的极其重要的因素。

The video which is part of the hospital's Infection Prevention drive which has already seen cases of MRSA drop by more than 60 per cent and C. difficile by over 50 per cent in the past 12 months.

这个视频是医院感染预防项目的一部分，这个项目在过去12个月中，已经使该医院的耐甲氧西林金葡菌病例下降了超过60%，难辨梭菌病例下降超过50%。

Over time and with the past 30,000 years of repeated history, so many discarnate humans continuing in an afterlife were taking so much of Earth's chi that Earth has continued to descend and descend in vibration.

随时间，过去30，000年重复着历史，如此多脱离肉体的人类继续在一个夺获着地球如此多的 chi 的来生中，以至于地球的振动下降了再下降。

The GLDH gene expression showed a continuing reinforcing trend after morphine injection compared with control group, even after drug withdrawal. The ADA mRNA contents in morphine group Ⅰ,Ⅱ and withdrawal group Ⅰ,Ⅱ were 2.65,1.89,1.18, and 0.87-fold of that in control group dividedly. The ADA gene expression increased after morphine injection and fell gradually after withdrawal.

结果：吗啡Ⅰ、Ⅱ组及停药Ⅰ、Ⅱ组大鼠肝脏GLDH mRNA含量分别为对照组的1.02、1.09、1.16及1.46倍，吗啡给药大鼠肝脏中GLDH基因表达随给药时间延长而持续增强，自然停药一定时间内大鼠肝脏中GLDH mRNA含量仍持续增高；吗啡Ⅰ、Ⅱ组及停药Ⅰ、Ⅱ组大鼠肝脏ADA mRNA含量分别为对照组的2.65、1.89、1.18及0.87倍，吗啡Ⅰ、Ⅱ组大鼠肝脏ADA的基因表达均比对照组明显增高，自然停药后大鼠肝脏ADA表达逐渐下降，停药7 d时下降至接近对照组水平。

Different climate change in west and east part of north China in recent years is major reason for this phenomenon, not vegetation cover, but degenerated vegetation cover, corresponding to abnormal droughty climate during these period, is one of reasons for abnormally high dust activity in the end of 9Os'in Huabei Plain.

九十年代末，对应于我国北方地区，特别是华北地区干旱少雨的气候条件，植被覆盖状况有明显下降的趋势，这可能是世纪末华北地区沙尘活动频繁的一个重要原因，但我国西部沙尘源区沙尘气溶胶光学厚度仍然保持继续下降的趋势。

The research of swelling dynamic behavior shows that the electrolytical ions in swelling media have a great effect on the swelling behavior of PVA gel and the equilibrium swelling ratio in physiological saline is less than that in aqueous media.

溶胀特性研究显示，PVA水凝胶在生理盆水中的平衡溶胀比小于其在蒸馏水中的平衡溶胀比，凝胶的平衡溶胀比随浓度和冷冻－解冻次数的增加而下降，其下降趋势满足幂函数的变化规律；水凝胶的溶胀过程符合溶胀动力学方程。

As the addition of dry time, solid content shows the downtrend of little scope, dry time is negligible to the influence of solid content not plan; as dry temperature elevatory, the solid content of adhesive is shown substantially downtrend, temperature is more apparent to the influence of solid content, but in 115 ℃- between 125 ℃, the change of solid content is very little, the influence is negligible not plan.

随着干燥时间的增加，固体含量呈小幅度的下降趋向，干燥时间对固体含量的影响可以忽略不计；随着干燥温度的升高，胶粘剂的固体含量呈大幅度的下降趋向，温度对固体含量的影响比较明显，但是在115℃-125℃之间，固体含量的变化很小，影响可以忽略不计。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
