To ensure human body's health, sanitation in driving vehicles crossing the tunnels as well as operation safety of tunnels, the present study take a highway tunnel(620m) as an example, combined with the data analyse of highway tunnel intelligent monitoring system to advance a discharge standard of NO2 concentration in highway tunnels and revelant ventilation solution.

为了保证城市公路隧道行驶机动车内人的健康、卫生和隧道的营运安全，本文以某隧道(620米)工程为例，结合隧道智能监控系统数据的分析，提出了在城市公路隧道内二氧化氮浓度的排放标准，并且提出了相应的通风方案。

The experts behind the discovery say elephants are capable of vocal imitation, joining a select group of animals that includes parrots, songbirds, dolphins, and humans.Zoologist Joyce Poole was the first to notice some rather unelephantine noises emanating from a group of semiwild, orphaned elephants in Tsavo National Park, Kenya. She managed to track the sounds to a female named Mlaika. But the ten-year-old's powers of mimicry were so developed that the task wasn't easy."I was sometimes unable to distinguish between the distant trucks and Mlaika's calling," said Poole, the scientific director of the Amboseli Elephant Research Project."This is what first made me wonder whether she could possibly be imitating the truck sounds."Poole said others in Mlaika's group have been heard to make a similar noise, which is quite different from any call previously recorded in elephants.
