未减弱的

The density of active centers increases first and then decreases with the increase of the amount of Ti.(3)The activity of hydrogenolysis decreases with the increase of the a

另外，当催化剂中Ti的含量在0.25—1.0％时，上述各种参数随Ti量而变化的幅度不大，这可能是因为催化剂中未被还原的Ti~(4+)具有增强Pt的活性的作用，因此它部分抵消了Ti~或Ti~0所起的减弱Pt的活性的作用。

The simulation outcome demonstrates that various control measures after April 20,2003 in Beijing and the public holidays starting from May lst to May 5th have a significant impact on containing the epidemic situation. The most dangerous days, around April 27, when the number of uncontrolled SARS patients in the society reached at its peak, can also be calculated. The SARS infectiousness number newly reported in Beijing has been at a low level since May 20. But simulation experiments describe that it may fluctuate with import of SARS infectiousness from outside Beijing, weakening of quarantine, more social activities, and so on.

同时应用动力学模型，对北京的SARS疫情进行分时间段的模拟与SARS实施控制因素影响分析，结果表明，2003—04—20以后一段时间内实行的各种控制措施，以及5月1日—5月5日的长假对于北京SARS疫情的控制是非常有效的；而4月27日左右北京市社会上未得到有效控制的SARS病人数达到高峰，是最危险的时期。5月20日以后，北京的SARS疫情基本保持在低发的平台期，但是如出现较多的外来SARS病例输入，而内部隔离强度又减弱、社交活动增加等情况下，北京SARS疫情可能会有一定程度的波动与反弹。

In the experimental tectum, the expression of GFAP in the right SO was higher than the expression of GFAP in the left SO during 1d-60d after after optic nerve damage. The expression of GFAP in the right SO was familiar with the expression of GFAP in the left SO during 85d after optic nerve damage, but the expression of GFAP in SO in the experimental tectum was higher than that in the normal tectum. The result of GFAP expression in the experimental retina and tectum showed that AStrocyte took part in the optic nerve regeneration and it might play an important role in optic nerve regeneration accidents.

在损伤1d后视网膜的神经纤维层和外核层外缘可见较为深的GFAP染色，在损伤3d后视网膜从内网层经内核层至外网层出现稀疏的垂直于视网膜长轴分布的线条状GFAP染色，随时间推移，伤后5d、7d、14d、28d上述染色进一步加深密集，到伤后60d和85d上述染色减弱，阴性对照的视网膜各层未见GFAP阳性染色；(5)正常鲫鱼视顶盖中在SO层内有较浅的黄棕色线条状GFAP染色，在SFGC层

The synthetic evaluation of soil biology---biological fertility indices were (0-40cm depth of soil, same below): 0.635 →0.074 →0.014 . Significant degradation of soil texture, obvious decrease of soil organic matter , and increase of the availability of aluminum were found in the degradation series. Along with the fast vanishment of vegetation, the number of soil microbe and enzymatic activities decreased drastically, among which protease activity degraded most markedly and was only detected in soil of ZR.

土壤物理性质中，土壤质地发生了根本性退化；土壤化学性质中，随着植被的退化，有机质含量的减少和Al的有效性的提高都很明显；土壤微生物和酶活性中，各类微生物的数量退化非常显著，其活性也随植被的退化急剧减弱，酶活性也大大降低，以蛋白酶活性降低最为显著，大部分退化地段未检测出蛋白酶的活性。

Psychic powers and extra-sensory perception rank among the top ten unexplained phenomena if for no other reason than that belief in them is so widespread. Many people believe that intuition is a form of psychic power, a way of accessing arcane or special knowledge about the world or the future. Researchers have tested people who claim to have psychic powers, though the results under controlled scientific conditions have so far been negative or ambiguous. Some have argued that psychic powers cannot be tested, or for some reason diminish in the presence of skeptics or scientists. If this is true, science will never be able to prove or disprove the existence of psychic powers

对灵力和超感知觉的信仰流布甚广，就凭这一点，这两样东西也应该进入十大未解之谜的行列许多人相信，直觉就是灵力的一种表现形式、一种获取有关世界或未来的特异知识的方法研究人员已经对一些自称拥有灵力的人进行了测试，但是迄今为止，他们在受控实验室条件下得到的都还是否定或含糊的结果有些人辩称灵力不可测试，因为它会因怀疑论者或科学家的在场而莫名其妙地减弱如果这是真的，科学就永远无法证明或驳斥灵力的存在

The results show that the cyclic softening is featured in bothvariedly hardened steels under strain controlled in the amplitude range of Δε_t,/2=0.6 - 1.8×10~(-2). The softening effect is mainly gathered in the prior some cycles.And the stress amplitude varies slightly in the sequential cycles, i. e. the softeningeffect is minified.

结果表明：在应变幅为Δεt/2=0.6—1.8×10~(-2)范围内，不同硬化状态的试验钢均表现为循环软化特性；软化效应主要集中在前几周，在随后的循环过程中应力幅变化较小，软化效应减弱；整个循环过程中，未观察到明显的应力饱和现象。

By introducing fused-silica prims tocompensate the group velocity dispersion, as short as 8.5 fs pulses at 710nm isachieved without employing chirped mirrors. In our knowledge, this is the shortestpulses produced domestically from a KLM Ti:sapphire laser in China. Finally, The amplitudes and phases of femtosecond pulses generated from theKLM Ti: Sapphire laser are diagnosed by using the technique of second-harmonicgeneration-frequency-resolved optical gating.

第三，在实验上，在自行研制的自锁模钛宝石飞秒激光器中，改进腔的设计，较好地减弱了腔内频率依赖的腔模效应对频谱展宽的限制作用，获得了最宽达144nm的宽带光脉冲频谱输出，并在未采用啁啾镜的情况下，利用三阶色散系数小的熔融石英对补偿色散，获得了8.5fs光脉冲输出，为目前国内最好记录，达到国际先进水平。

At growth period of Moso bamboo, because the root has not grown completely and has little influence on rhizosphere soil, so the score was the highest. The score of rhizosphere soil decreases as the growth and root gradual development of Moso bamboo. The rhizosphere soil quality increased at later stage of Moso bamboo because of gradually weakened growth and the increased litter and microorganism activity.3.The demands for nutrients of Moso bamboo at different growth periods were different. It was different in the demand for nutrients of Moso bamboo at different growth period.

成竹期由于根系未完全形成，对其根际土壤的影响较小，因而成竹期得分最高，随着毛竹生长，根系渐渐发达，对其根际土壤的影响日渐扩大，造成根际土壤得分渐低，后期毛竹生长逐渐减弱，对其根际土壤的影响也随之减少，加上林中凋落物的增加和微生物活动增强，其根际土壤的质量有所增加。3、不同生长阶段毛竹对营养元素的需求有所不同。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
