This study focuses on the chain for the multi-speed bicycle. Design space for the freewheel on bicycle is limited by frame, riding posture, etc. However, the number of gear ratios in this design space increased with added more sprockets are the trend on the bicycles.

本论文主要研究对象为自行车上传动系统中的链条元件，由於自行车飞轮受到车架、骑乘姿势所形成的空间限制，必须在有限空间内增加飞轮片数增加齿数比，达到变速换档的舒适性。

If you want a cheap vocation, travel on an ocean freighter.

如果你想过一个花费少的假期，就乘海轮旅行。

On that selfsame day, Ni went to her office to petition for a hiatus from work, and the following morning she fretfully boarded a seven o'clock Shanghai Airlines flight back to her hometown in Shanghai.

当日，燕妮去公司请假。翌晨，乘7点半上航的飞机，飞回上海老家了。

Yes. I have sailed on a ship. The Fast Frigate.

是的， 我乘船航行过，乘的是"快舰号"。

Going over If we ride a ripple of camels And surge on the vast desert deep in sleep, If a bunch of rings light and low Rip into the loneliness of twilight, We will put up tents everywhere, And let hardship be spawned into deep sleep Acid and sweet, a big block of thickness That can soak every pore of our bodies; Don't care whether we can dream of the oasis, For we will have been fuddled; We will not have to do anything if stealthily buried by A cyclone with sands and stones.

14远行如果乘一线骆驼的波纹涌上了沉睡的大漠，当一串又轻又小的铃声穿进了黄昏的寂寞，我们便随地搭起了蓬帐，让辛苦酿成了酣眠，又酸又甜，浓浓的一大块，把我们浑身都浸过；不用管能不能梦见绿洲，反正是我们已烂醉；一阵飓风抱沙石来偷偷把我们埋了也干脆。

Programmable logic gate, I-bit nanopipeline full adder and 4×4 nanopipeline array multiplier based on RTD-CMOS circuits are presented in this paper.

文中对数字电路中比较典型的可编程逻辑门、全加器电路进行了设计与模拟，并在此基础上对4×4阵列纳米流水线乘法器进行了结构设计。

As an example, in the design of a 4-bit ripple carry adder, the second and fourth full adders do not use output inverters for carry generation. one inverter delay is eliminated for every two full adders in the adder chain, and four transistors are reduced. Similarly, in complex designs like the multiplier, the output inverters for generating sum and carry can be used in alternative stages, thereby improving speed and reducing area.

例如，在4位行波进位加法器中，第2级和第4级的加法器不需要用输出反向器进行进位产生，因此，加法器链上的反向器延迟每两级全加器抵消一次，因此可以减少4个晶体管，类似的，在乘法器这样的复杂设计中，用于产生"和"以及"进位"的输出反向器可以用于其它方面，因此可以改善电路的速度和减小面积。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
