Firstly , I expounded the background of this subject which are the conception and basic characteristics of the NDN network architecture and the BGP protocol .

本文依托青年科研创新专项项目，首先阐述了课题背景，NDN网络架构的思想和BGP协议的概念和基本特点。

OV-17 fixed phase and NDN inner mark were adopted . The precision standard deviation is 0.56 , the coefficient of deviation 0.59 % , average recovery 99.84 % .

采用OV-17固定相，NDN内标，检测精密度标准偏差为0.56，变异系数为0.59%，平均回收率为99.84%。

Through the research and analysis of the testing results , it can effectively verify the effectiveness of the function of the the NDN network test and prove the feasibility of the the NDN network design scheme .

为了验证NDN网络设计方案的正确性和可行性，按照指定的测试指标，执行测试，通过研究分析测试结果，验证NDN网络测试系统功能的有效性，从而证明NDN网络设计方案的可行性。

Objective To investigate clinic manifests and renal biopsy indicator for type 2 diabetic mellitus ( DM ) patients with renal damage who were questioned to be non-diabetic nephropathy ( NDN ) .

目的研究2型糖尿病（DM）伴肾脏病变怀疑合并非糖尿病肾病（NDN）患者肾活检的指征及临床特征。

Results 50.9 percent of the patients was DN , while NDN was 49.1 percent was NDN in which mesangial proliferative nephritis was found most ( 1 / 3 ) .

结果糖尿病肾病（DN）占51%，非糖尿病肾病占49%，其中系膜增生性肾炎最多见占1/3。

The present study showed that low-frequency rTMS had a neuroprotective effect on the NDN , which might be due in part to increased BDNF and GDNF protein levels in the SN induced by rTMS .

研究表明低频rTMS对黑质多巴胺能神经元具有保护作用，而这可能部分与rTMS诱导黑质区BDNF和GDNF蛋白表达水平增加有关。
