Also subsea tunnel projects in other Nordic countries will be presented as they have been designed and constructed according to Norwegian subsea tunnel principles.

相应地，介绍了其他北欧国家的海底隧道，这些隧道大多也是根据挪威海底隧道的经验进行设计和施工的。

It is widely used in express-way,railway and tube tunnel and enjoys a glaring feature of being envi-ronmental-friendly, noise-absorbing,fireproof,corrosion resistant,therefore it is suitable for severe environment characterized by gale,heavy rain,strong sunlight,dampness and heavy dust.

我厂研发的新型"隧道专用吸音板"和"铁路隔音屏障吸音板"等系列产品，安装在铁路两侧和隧道内壁，它具有隔音吸音、降噪、A级防火防潮、耐腐蚀、抗老化、环保美观等功能，能有效降低道路机电车辆产生的噪声，美化道路、隧道环境。

This software is visual application system based on the structure design of tunnel kiln.

隧道窑的结构设计决定隧道窑的先进性，合理的隧道窑设计有助于降低能耗，提高热效率，保证陶瓷产品的质量[1 ] 。

According to the causes of tunnel seepage and problems of crack and durability of masonry liner concrete, the application of fly ash concrete is tested based upon its characteristics including placeability, watertightness, low heat of hydration small expansion and shrinkage, high strength of long term.

通过对隧道渗漏水原因的分析，针对隧道衬砌混凝土的开裂和耐久性问题，根据粉煤灰混凝土和易性好、水密性好、水化热低、膨胀收缩小、长期强度高的特点，对粉煤灰混凝土应用于隧道衬砌中进行了试验研

Using the ground and vehicular test systems,many parameters such as pressure change, wind caused by train ,micro-pressure wave and vibration acceleration of the wall of tunnel were tested.

利用地面和车载测试系统，对列车车体表面、车厢内部、隧道壁面空气压力变化、隧道内列车风、隧道口微气压波和隧道壁面振动加速度等参数进行测试。

Bench cut method; benching stepping method ...

将隧道断面分层，各层的开挖与衬砌沿隧道纵轴错开并进的隧道施工方法。

RESULTS: In the SH-rhBMP-2 group, sparse chondroid tissue could be found at the 2 weeks of operation, which arranged orderly along the tibial tunnel from 4 to 8 weeks, tendon adhered to adjacent tissue stably, and bony tissue was appeared at the 12 weeks.

结果：透明质酸钠-重组人骨形态发生蛋白2亚组在术后2周隧道内见稀疏软骨样组织，4~8周时隧道内见沿骨隧道排列的软骨样组织，双股肌腱之间形成稳定组织连接。l2周时出现部分骨样组织包裹肌腱。
