And it could be the next biggest thing in urban transportation - on two wheels. GM has teamed up with Segway to develop this two-seated electric vehicle. Weighing in about 300 pounds, the vehicle runs on a lithium-ion battery, and could reach a top speed of 35 miles an hour.

这可能时两轮交通工具在城市交通上发生的第二大事了，GM和Segway共同制造了这种两轮的电动交通工具，它重约300磅，动力能源依靠锂电池，最高时速可达每小时35公里。

The result shows that the magnetic field effectively confines the electrons. Electrons are collected in a small region. Due to the special electromagnetic field, the ion beam has a two-peaked distribution.

结果发现圆柱形阳极层等离子体加速器的磁场对电子有明显的约束作用，电子集中于阳极附近很小的区域内。

The circuit system for the portable sealed tube neutron generator with neutron yield more than 1010n/s is described in this thesis. The ion source circuit, the reservoir circuit and the target high voltage circuit of this neutron generator are studied in detail.

论文对所研制的新一代便携式1010n/s中子发生器电路进行了全面的介绍，对离子源电路，存储器电路，特别靶极高压电路结构进行深入剖析。

The central 5, 5'-disubstituted bipyridine units of each ligand coordinate theNi or Fe ion, while all the terminal 6-monosubstituted bipyridine units of the ligands keep free of coordination, as the result trinuclear triple-stranded helicate 〓 can not form. This is considered to be caused by the steric hindrance of the methylene substituents α to the chelating nitrogens of the terminal bipyridine units and the strain caused by linkage mode.

配体L〓与Ag作用得到〓，两个配体链相互缠绕着两个Ag离子周围形成双股螺旋结构并以头尾式排列(见图3)，由于配体中位于配位N原子α或β位的末端甲基或次甲基取代基的空间位阻阻碍了头对头式异构体的形成，也正是由于配体头尾式排列而使Ag双股螺旋得以形成，这一结果表明该螺旋体的组装过程中自发地采取了空间阻碍尽可能小的那个构型。
