A new road maintenance machine in winter is introduced, which is used for spreading of anti skid and snow melting material. 介紹了一種新型的道路冬季養(yǎng)護(hù)機(jī)械，其主要用于撒布防滑、融雪材料。
The structure, function and design of the software and hardware of the computer measurement control system of the SY A test stand for anti skid devices are described. 介紹了SY— A型防滑器試驗(yàn)臺(tái)的結(jié)構(gòu)、功能及其微機(jī)測試控制系統(tǒng)的軟硬件設(shè)計(jì)。
The question that was never resolved was whether drivers respond more positively to measures that reduce accidents (anti-skid brakes) or to those that reduce injuries (airbags). 當(dāng)時(shí)遺留的問題是：司機(jī)對減少事故（防滑剎車）的措施有更加積極的反應(yīng)，還是對減少人身傷害（安全氣囊）的措施更加支持？
