In this study, AlGaN/GaN hetero-junction photo-transistors in detecting ultraviolet spectra have been fabricated and characterized. One of the HPTs features as low-temperature grown GaN insertion layer between based and emitter layers to reduce dark current. The internal gain and response time are also studied for the HPTs with and without the LT-GaN layer.

中文摘要本论文针对氮化镓/氮化铝镓系列异质接面光电晶体作为紫外光波段侦测器之相关制作与研究，包括於磊晶结构中有无插入一层低温成长氮化镓层之两种异质接面光电晶体，并比较其元件讯号放大效果以及响应时间的改变。

METHODS: Peripheral nerve injury models of New Zealand rabbits were established. The immediate repairing group received suture immediately after injury; For the other three groups, the two broken ends of their nerves were fixed on sarcolemmas temporarily and their wounds were sutured layer by layer. Then they were opened respectively at week 2, week 4 and month 3 after injury, to receive epineural suture with non traumatic 10-0 nylon suture under operating microscope, after which wounds were sutured again.

建立成年新西兰大白兔周围神经损伤模型，即时修复组立即缝合伤口，2周后神经修复组、4周后神经修复组、3个月后神经修复组采用神经两断端分别固定于肌膜上，逐层缝合伤口，2周，4周，3个月后重新打开伤口，在手术显微镜下用10-0无损伤尼龙针线进行外膜缝合修复坐骨神经，缝合伤口。

Since 2000,erasable layer-by-layer films have received much attention for their potential application in the functional delivery system.

自2000年以来，具有可消除性的LbL膜因其在药物缓释领域的重要应用前景而逐渐受到广泛关注。

The results showed that erectness of coupling pattern between upper-layer jet and low jet and a divergence area, which came forth in right of upper-layer jet provide favorable surrounding conditions. The most intensive moisture convergence, the strongest ascending movement and the most instable convection stratification all occurred in the rainfall center. The rainstorm occurred at the warm and wet side of the negative value center of the moist potential vorticity and relative MPV, which had certain indicative significance for the forecast of rainstorm areas.

结果表明：高低空急流的优势配置，耦合形势的建立以及高空急流右侧的强辐散场的存在为暴雨的发生提供了有利的环境条件；暴雨区中上升运动和水汽辐合均大于周围区域，中低层为对流不稳定层结；暴雨区位于湿位涡和湿相对位涡负值中心附近偏暖湿气流一侧，对暴雨落区预报有一定的指示意义。

This research was conducted in degraded rangeland at the southwestern edge of the Mu Us sandland, Yanchi county, Ningxia, the soil seedbank features and its relation to vegetation was analyzed using similarity analysis and ordination method, the results show that seeds within soil distribute mainly in 0~5 cm soil layer, less seeds in 6~15 cm soil layer in exclosed and non-exclosed rangeland, for seeds in exclosed soil, species richness and diversity index H are higher, while D is lower, exclosure measure, generally speaking, can increase plant species and amount of vegetation and seeds in soil, some annual plants, mesophytes and halophytes appears in the soil or surface.

以毛乌素沙地西南缘宁夏盐池县的退化草场为研究对象，采用相似性分析和排序方法对封育和未封育草场土壤种子库的特征及其与地上植被间关系进行了研究，结果表明无论封育区还是未封育区，土壤种子库中的种子主要分布于0~5cm的土层，6~15cm土层的种子数很少；封育区土壤种子库的物种丰富度大于未封育区，物种多样性则表现为H 值较大，而D值较小，总体上看封育措施可以提高地上植被和土壤中种子的种类和数量，一些一年生植物、中生植物和盐生植物开始出现在地面或土壤种子库中。
