利用PPMgO：LN晶体，获得了1571~1679nm范围内的宽带输出。5、提出了一种利用倾斜周期极化晶体非共线光学参量振荡产生宽带光源的新方法。6、提出了一种利用非周期极化铌酸锂晶体电光效应实现双波长激光器调Q的新方案。

So we conclude that phylogenetic relationships between different aphids and their endosymbiotic bacterium Buchnera may be different, and this conclusion is accordant with previous study. This work not only fill a gap on phylogenetic relationships between the three aphids, M.

这一工作不仅弥补了这三种蚜虫与其内共生菌Buchnera之间的进化关系空白，同时有助于我们在了解这些蚜虫Buchnera的系统进化特征的基础上，进一步全面地了解了这三种蚜虫的内共生菌Buchnera。

Increased at different extent and the content of GA3 and ZR were all down under drought stress, while the content of IAA had a different trend according to different material. The general trend of coordination among 4 endogenesis hormones was closeing the stoma and promoting the growth of root,whereas the coordination mechanism of different Dactylis glomerata L.

盆栽控水条件下4份鸭茅内源激素变化的研究结果显示，随着干旱胁迫程度的加强，四份鸭茅ABA含量整体呈上升趋势，GA3和ZR的含量则呈下降趋势，IAA的含量因材料不同表现出不同的变化趋势，干旱胁迫下四种内源激素的协调总趋势是向着气孔关闭，促进根系发展的方向进行。

It is well known that retinal pigment epithelial cells are predominant proliferative cells in PVR which is an excessively wound healing response occurring after RPE cell wounding. The activated RPE cells migrate from their normal, sessile state to vitreous and onto both surfaces of the retina, in which they begin to dedifferentiate, migrate, proliferate, change phenotype and secrete ECM.

既往研究证明视网膜色素上皮(retinal pigmentepithelial，RPE)细胞是参与PVR的主要细胞，PVR是视网膜脱离后RPE细胞损伤的一种自我修复过程，是一种过度的眼内创伤修复反应；RPE细胞在正常位置上处于静止状态，而在某些病理条件下，如视网膜裂孔形成和视网膜脱离后，RPE细胞脱离原位，开始去分化、移行、增生、发生表型转化并分泌胶原等ECM，最终在视网膜前后表面和玻璃体内形成具有收缩能力的增生膜，造成牵拉性视网膜脱离。

In this paper, cholinergic neurons was mapped in the two kinds of birds (Emberiza rutila and Fringilla montifringilla) by using immunohistochemical method.The soma size and cell density of cholinergic neurons in the three song control nuclei, the higher vocal center, the robust nucleus of the archistriatum and area X, were measured and compared. Here we discussed the distribution of cholinergic neurons and their effect on the process of song producing and song learning.

本文以中国北方地区常见的两种鸣禽栗鹀和燕雀为材料，应用免疫组化方法，对两种鸣禽发声控制核团，即上纹状体腹侧尾核或高级发声中枢、古纹状体粗核、X区内胆碱能神经元的胞体大小和胞体密度进行了观察测量，旨在探讨胆碱能神经元在发声控制核团内的分布情况及其在鸣啭产生和学习过程中的作用。

This paper focuses on how to calculate GPS satellite orbit parameters through IGS data. Choosing a group of appropriate parameters, and the relationship between satellite position in ITRF and these parameters are founded, and these parameters can be estimated using some successive ephemerides. Three different methods are introduced detailedly.

本文以IGS精密星历为基础，深入研究了利用精密星历计算GPS卫星轨道参数的模型与方法，并对三种不同的计算方案进行了比较研究，其目的是寻找一种合适的计算方法，得到能够正确反映一个较长时间段内(如800天)轨道参数随时间变化的规律。

Before fissuration, osmotic adjustment occurred by the addition of solute to cells and decreasing the loss of water in the body, so that it could maintain normal turgor pressure during drought. After fissurate growth, turgor pressure was maintained by higher cell and tissue elasticity lower ε(superscript max and by osmotic adjustment for normal plant development in dry conditions and to avoid dehydration under water stress during the drought period, but it also became more sensitive to water stress. The ability to maintain turgor pressure varied from strong to weak during the period before, during and after fissuration. Fissurate growth decreased the ability of P. mongolica to maintain turgor pressure and led to changes in walls related to drought tolerance.

结果表明：1未劈裂绵刺主要通过增加细胞内溶质，减少细胞内的水分丧失来进行渗透调节，从而在干旱胁迫下能够维持正常的膨压。2己劈裂绵刺通过渗透调节和高的组织弹性两条途径来共同保持膨压，以抵抗不良的生存环境；同时对环境水分胁迫具有较高的敏感性。33种状态绵刺保持膨压的能力由强到弱依次为：未劈裂绵刺、正在劈裂绵刺、已劈裂绵刺。4劈裂的发生导致绵刺保持膨压能力的降低，同时耐旱方式和途径发生了变化。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
