查询词典 school bus

Although bus transit is excellent for serving dispersed destinations, on major urban corridors rail tends to be more effective at attracting riders and more cost effective overall, since trains tend to offer a more comfortable ride, are generally propelled by electric motors rather than internal combustion engines (so train stations tend to be more pleasant than large bus stations), and can carry more passengers per unit.

虽然公交车在服务于目的地分散的情况令人满意，但在地铁主干线上，地铁更有效更便宜。乘坐地铁更更舒适。地铁有电动机驱动而不是内燃机（因此地铁站比大型汽车站更让人喜欢。），而且每节载客量更大。

The system adopts CPU board with fast processing elevator operational program, data signal exchange, and HMI screen, which can make sure reliable operation and high speed. It also has PHILIPS SJA1000T field CAN bus, 82C251 Bus interface and the latest serial storage technique to record data. The functions of external watchdog and control chip internal watchdog compose two-level procedure monitoring, so as to ensure the normal operation of the control program. Heavy-current switch power LM2576 ensures the stable system working power, which has low requirements for the power supply. High-speed optoelectronic isolator and internal frequency division technology can make NW3P08-41C (42C) CPU receive the input impulse up to 1-phase 100 KHZ*2 CHANEL or 2-phase 50KHZ*1 CHANEL 32bit.

The most dramatic moment Tower Bridge has witnessed occurred in December 1952 when a London 'Double-decker' bus entered the Bridge while it was opening the point of no return. The bus cleared the gap between the opening bascules.

在伦敦塔桥的历史中最具戏剧性的一幕发生在1952年的12月，有人目击了一辆双层大巴在塔桥升起的时候驶入，当时升起的桥板已经不可能再放下了，于是这辆大巴就卡在两个升起的桥板的中间。

The selection principle of bus interface chip and solution of bus conflict are introduced,together with its concrete hardware cir- cuits and software block chart are given.

分析了总线接口芯片选择原则和总线冲突解决方案，给出了系统实现的硬件接口电路和软件实现详细框图。

That was bad enough, but I took three people with me: two English girls who had stopped in Hot Springs on a cross-country bus trip and looked the way you look after two or three days on a bus; and Glenn Mahone with his Afro and dashiki.

我的这形象已经够糟了，何况还有另外三个人和我一起：两位乘坐巴士横穿全美的英国女孩，此时来到温泉城作短暂停留。她们看上去就是那种在巴士上待了两三天的样子。另一个人便是格兰。

At first, this paper introduces the receiving and transmitting mechanism about the ARINC629 data based on the ARINC629 protocol. With the computer interface technology, it gives the whole design of the communication card which is divied into three modules, such as the PCI bus interface module, the subsytem processer and memory module and the ARINC629 bus interface module.

论文首先根据ARINC629总线协议规范，明确了ARINC629总线协议的数据发送和接收机制，并结合当今计算机接口技术，确定了数据通信卡的总体方案，将数据通信卡划分为三个模块进行设计，即PCI总线接口模块，通信卡子系统处理器和存储器模块以及通信卡与ARINC629总线接口模块。
