To elucidate the molecular mechanisms underlying the neural plasticity after CNS injury, the gene expression profile in the rat hippocampus following perforant path transections was explored by several methods including custom differential screening, custom cDNA array and cDNA microarray.

为了阐明中枢神经系统损伤后神经可塑性的分子机制，本实验探索了多种方法，包括传统差异筛库、传统cDNA array和cDNA microarray，对穿通纤维切断后大鼠海马的基因表达图谱进行了研究。

To elucidate the molecular mechanisms underlying the neural plasticity after CNS injury, the gene expression profile in the rat hippocampus following perforant path transections was explored by several methods including custom differential screening, custom cDNA array and cDNA microarray. Of 2300 cDNA clones from low-abundance rat brain cDNA bank, 6 were identified as differentially expressed genes/ESTs in the hippocampus 35 days after lesion, in which none was confirmed by Northern blot. Of 8000 cDNA elements, custom cDNA array identified 47 as differentially expressed genes/ESTs with above 3-fold changes in the hippocampus 35 days after lesion, in which 25 were up-regulated and 22 down-regulated.

After some generations the population diversity would be greatly reduced and the algorithm might lead to a premature convergence to a local optimum. To circumvent these shortcomings, the chaotic dynamic system is introduced in the studies of chemometric algorithms. The chaotic mapping itself is very sensitive to the initial state in a manner similar to the statistical randomness but with its underlying patterns appearing to be phantasmagoric in a deterministic style.

神经网络是一个优异的非线性建模工具，但其突出的缺点就是潜在的预收敛到局部最优点或过拟合导致的错误预报模式；遗传算法用于优化过程其目的是为了避免陷入局部最优点，但事实上由于在传统遗传算法的进化过程中只有少数最好的成员被保留下来用于产生子代成员，经过一定代数的进化后群体成员的多样性就会显著下降，也很可能过早收敛到局部最优点。

Al becomes a major factor limiting crop growth and yield when solubilized in acid soils to phytotoxic species Al3+, but the mechanism underlying the Al toxicity remains largely unknown.

铝毒是酸性土壤中植物生长发育的主要限制因子，但目前关于铝毒的生理学机制并不很清楚；另外，关于园林花卉的铝毒害研究尚未见报道。

Pleurisy, also known as pleuritis, is a serious condition that occurs when the two thin membranes lining the lungs are infected, usually as a result of a severe chest infection, pneumonia, or some other underlying lung disease.

性胸膜炎，也称为性胸膜炎，是一个严重的状况时，所发生的两薄膜衬砌肺部感染，通常是由于严重的胸部感染，肺炎，或其他一些潜在的肺部疾病。

An alternative theory postulated by Schneider et al (1) and expanded on by Dernevik and colleagues (2) suggests that the event underlying round atelectasis is a local pleuritis that is caused by irritants such as asbestos.

另外一个理论是由Schneider等提出，并由Dernevik和他同事完善，认为球形肺不张基础是如石棉等刺激引起的局部胸膜炎。
