剧烈的反应

Periaqueductal gray neurons exhibit increased responsiveness associated with audiogenic seizures in the genetically epilepsy-prone rat.

总之，听源性惊厥发作诱导PAG内大量神经元表达c-fos基因，揭示了PAG内神经元功能活动的剧烈改变，N'Gouemo［12］的电生理研究也发现，听源性惊厥易感大鼠PAG内许多神经元表现为异常的高反应性状态，而且出现与强直相关的神经元异常放电，这些都进一步说明PAG参与了听源性惊厥发作过程，但其中的神经化学机制尚需进一步探讨。

In the highheating rates, Al nanopowders were heated above 560℃rapidly, and then the oxidize shellcracked and combusted due to the fusion of the core part Al. This oxidation process wasacute, and had only one phenomenon of exothermal and mass gain.

在高加热速率下，纳米铝粉温度迅速被加热到560℃以上，芯部的铝熔化造成氧化铝壳层的破裂燃烧，氧化反应剧烈，仅有一次放热和质量增重现象。

Fibered reinforced wide-beam frames exhibit large displacement and large damping ratio after yielding of structure. Steel fibers contributed to causing less damage during high-level ground motion.

钢纤维扁梁框架的最大位移反应和阻尼比均比普通砼扁梁框架要大，钢纤维可以降低预应力砼扁梁框架在剧烈地震运动下的结构损伤。

The Solidification temperature range was defined as 110-200℃ by DSC analysis. More accelerant used can increase the casing samples dynamic performance, but more than enough accelerant can induce a severe solidified reaction that result in a smaller polymeric meshwork and reducing the sample's performance. Normally the Accelerant dosage can be 2 portions; The Epoxy resin CFRP has a obvious better performances than the Vinyl-ester Resin CFRP, i.e. had a Bend Strength of 1516MPa, LSS of 85MPa, also Tg raised to 195~C~ When used the end-carboxyl polyether to reinforce the epoxy resin, the casing sample's SS, BS and Crack Elongation all increased geminately. The CFRP performance also increased a little, that is because the performance of the CFRP mainly contributed by the CF. The reinforced resin improved the interface between the CF and resin that contribute to the little increasing.

通过DSC分析确定了该环氧树脂的固化温度范围为110~200℃，促进剂增加会提高浇注体力学性能，但过多的促进剂会使固化反应剧烈，聚合网络减小，使浇注体性能下降，一般用量为2份左右；以环氧树脂为基体的复合材料性能明显比以乙烯基酯树脂的性能提高，弯曲强度达到1516MPa，层间剪切强度达到85MPa，同时Tg也上升到195℃；用端羧基聚醚增韧环氧树脂后，其浇注体的拉伸强度、弯曲强度及断裂伸长都成倍增加，复合材料的性能也有所提高，但提高幅度不大，因为复合材料的力学性能主要由碳纤维承担，树脂增韧后改善了复合材料的界面性能。

A soft silvery-white metallic element of the alkali group that ignites spontaneously in air and reacts violently with water, used in photocells and in the manufacture of vacuum tubes.

铷：一种银白色的软的碱性金属元素，与空气接触会立即燃烧，与水反应剧烈，用于光电池和制造真空管。

But there are some long-term sequel associated with amphetamine abuse , such as, re-exposure to a relatively low dose of amphetamine will often prec ipitate a psychotic episode in former amphetamine addicts who have been abstin ent for months to years.

长期重覆使用安非他命者，会产生非常类似妄想性精神分裂的精神病变，此种安非他命引起之精神病经常在戒除药物后即消失殆尽，然而有一部分安非他命成瘾者，即使停药了几年后，当再次投与低剂量的安非他命时，会出现剧烈反应，包括情绪不稳定、精神症或癫痫等的症状。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
