Based on rail/wheel reaction and track/bride reaction theory and systems engineering theory, new vehicle-track and vehicle-track-bridge system dynamic models are established and discussed in details, including ballast track model and ballastless track model. The characteristics of the models are:(1) vehicle-track and vehicle-track-bridge system dynamic models are coupled in vertical and lateral;(2) track vibration on bridge is taken in account, track on bridge is considered as one or two layer continuous-point supported rail model, according to actual track structure, interaction between vehicle and bridge transfer from track structure;(3) three type of ballastless track models (tieembanked, elastic-tie-block, slab track) are presented;(4) models reflect the main feature of actual vehicle, track and bridge structure, the response computation frequency of models is relatively broad, which can be applied to analyze both low frequency and high frequency vibration.

基于轮轨相互作用和线桥相互作用特点，本文从系统工程角度出发建立了车辆、有碴轨道和无碴轨道、简支箱梁桥垂向和横向耦合系统动力分析模型，该系统模型具有以下特点：（1）车线、车线桥体系均考虑为垂向、横向耦合振动系统，车线间通过轮轨接触几何关系耦合，轨道与桥梁间通过轨道与梁体间的力与位移协调条件耦合；（2）充分考虑桥上线路在车线桥系统中参振作用，根据桥上线路轨道结构特点将桥上轨道结构模型具体化，即对桥上轨道结构视为多层支承体系，车桥间的动力作用通过轨道结构来传递；（3）建立了三种形式无碴轨道动力分析模型，即长轨枕埋入式、弹性支承块式和轨道板式无碴轨道模型；（4）系统模型详细，分析频带宽，适用范围较广。

Should be pointed out that Taihang Cement and can not be optimistic about the fundamentals, and the company's share price has now risen more than doubled Wednesday in such a massive collection of high levels with long-hatched line of hammerhead and accompanied by-day volume, from a technical perspective, this is a standard signal peaked.

It needs a sports or fingering weight yarn. Since it is a summer top, I ruled out wool and alpacas. I didn't want to use pure cotton, and I also wanted a variegated color... The choices are so limited.

在美国细线除了羊毛和一些真丝线外，其他材质的细线选择真的不多，尤其要适合夏天款式的，又不想要单色的，真的是没几种可挑。

When applied the spiny eel X chromosome library probes to the chromosomes of the two fish, different signals were distributed: in Siniperca chuatsi, besides some little signals on lot of autosomes, a large bright signal region was detected on the 8th chromosomes, which represented a synteny of spiny eel X chromosomes; but in Channa argus, no distinct synteny was found.

当以刺鳅的生物素标记X文库探针对鳜鱼和乌鳢的有丝分裂染色体进行染色体涂绘后，经过核型分析和统计分析表明，在这两种鱼的染色体上的杂交信号分布是不同的：在乌鳢中，除散在信号外，在其第八号染色体近着丝粒部位存在着一段较大的信号结合区域，应是与刺鳅的X染色体同源的保守同线群，而在鳜鱼中，只有散在信号分布于多条染色体上，没有明显的保守同线群存在。

After the commissioned of all 10.6m Tridents with ALX500 bodyworks, they mainly served Stanley and mid-level routes. They also served Shek O route as trial but they eventually replaced by 10.3m Tridents. In addition, those Trident can also be seen on routes serving Braemer Hill, trunk routes of Eastern District like 8 and 19. Some 10.6m Tridents decorated with all-over Cathay Pacific advertisements were deployed on M21 before the cancellation of it. In Southern District, 10.6m Tridents mainly served routes like 4, 94A, 590A, M590, 595 and holiday routes operated in swimming season.

新巴所有配亚历山大车身十点六米三叉戟投入服务后，除了主要行走赤柱及半山路线，亦曾试行石澳路线，但最后却被十点三米的同门兄弟接替这艰钜任务，再之后十点六米三叉戟便成为新巴车队中的百搭，驶上了宝马山服务乘客，又偶尔行走东区干线8及19，而已取消的M21线，也曾由一众披上国泰车身广告的十点六米三叉戟挂帅，而南区多条路线如4，94A，590A，M590，595及泳季假日线也不难发现十点六米三叉戟的踪影。
