For example, do the reports often say Not Fault Found?( NFF) or show the same repair being done ( the same component replaced) to all LRUs of a particular P/ N?

The FR resin was past several testing like China Railway Standard, Germany DIN 5510 and France NFF 16-101 and used in FRP industry.

After culturing 7 to 14 days, 3 weeks, 4 weeks and 8 weeks, respectively, cerebral slices were fixed, dehydrated and sectioned in cryostat. The sections proceeded with Nissl staining and neurofilament high molecular weight ( NFH) immunohistochemical staining.

取培养7~14d内每天的及培养第3周、4周和8周时的脑片，固定、脱水、切片后行Nissl和抗神经丝重链（NFH）免疫组化染色。

CONCLUSION: Decrease of HL activity and hyperlipemia exist in the process of glucocorticoid-induced NFH, but hyperlipemia can be relieved when agents are given to upgrade HL activity, and such agents can improve NFH and delay its progression.

结论：激素性股骨头坏死病程中存在高脂血症、HL活性下降，给予HL活性增强剂可以改善血脂紊乱状态，并可以改善骨坏死的程度，延缓其进程。

Objective To observe the expression and distribution of substance P ( SP), neurofilament-H ( NFH) in glomus tumors with chronic pain, and to discuss the process of chronic pain and the relationship with pain degree.

目的观察P物质（Substance P，SP）、神经微丝H（neurofilament H，NFH）在慢性痛血管球瘤中的表达和分布，探讨其在血管球瘤慢性痛的形成及其与疼痛程度的关系。

The C/ org. N and HA/ FA ratios of newly formed humus ( NFH) varied with the chemical composition of plant types as materials.

在相同的腐解条件下，不同物料腐解产物的C/有机N比值和HA/FA因物料种类而异。

Both chemical composition of plant types and soil water regime had no significant effects on the distribution of nitrogen forms of NFH.

土壤水分条件和植物残体的化学组成对腐解产物的氮素形态分布没有明显影响。

Question: Why do my MDNs take a minute to be created after a document has been received using AS2?

问：为什么我在使用AS2接收一份文档之后创建MDN需要花一分钟的时间呢？

Methods: The levels of urinary NTx and serum ICTP in 77 patients with malignant tumors were measured using ELISA.

方法：用ELISA方法测定77例恶性肿瘤患者尿NTx和血ICTP水平。

ICTP was much more worthy than NTX in diagnosis of breast cancer with bone metastasis.

成骨型生化指标在乳腺癌骨转移诊治中的价值不大。

Objective To investigate the effect of urine NTx in monitoring the effects of treatment osteoporosis with anti resorption drugs.

目的研究检测尿I型胶原交联氨基末端肽（NTx）监测抗骨吸收药物疗效的作用。
