semi-anechoic room

This system realizes such functions as vehicle positioning, remote switch control and wireless communication between dispatching room and locomotive, which provide a basis for the realization of semi-automation shunting. Firstly, vehicle positioning based on RFID is studied.

该系统实现了机矿车定位、道岔远程控制以及调度室与机车的无线通讯等功能，并在此基础上实现了机车的半自动化调度。首先，研究了基于RFID的机矿车定位技术。

In a temperature jump from room temperature to 100 ℃ both amorphous and semi-crystalline polymers and polymer blends showed AE while not in the sudden cooling to-60 ℃.

非晶态、晶态高聚物或共混高聚物在突然升温到100℃时有声发射，但在突然降温到-60℃时却不出现声发射，这可能也说明声发射与高聚物试样内形成空洞有关。

At room temperature, the equilibrium swelling ratios and swelling rates of the full-IPN hydrogels are lower than those of the semi-IPN hydrogels.

室温下，fun一IPN凝胶的平衡溶胀度和溶胀速率均小于Semi一IPN凝胶的平衡溶胀度和溶胀速率。

Among the three modes, the semi& automatic is divided into two styles: semi-automatic touch screen set control and semi-automatic controlling room set control.

其中半自动方式又分为两种：半自动触摸屏集控和半自动调度室集控。
