涟波

The adjustable amplitude range, symmetry and low ringing of the monocycle pulse are important to judge the performance of the pulse generator. Furthermore, the pulse generator should avoid the process variation and be suitable for different requirements.

目前脉波产生器的研究中，以脉波的高度可调性、对称性和低涟波为最重要，再者由於晶片中的制程变异或是需应用於不同的情况，因此目前的脉波产生器研究皆以此目标迈进。

In this thesis, we propose two pulse generators whose pulse amplitude is adjustable. These pulse generators use the second-order transient circuit at over-damping mode to generate the adjustable monocycle pulse with good symmetry and low ringing in the simulation and measurement.

本论文提出两个脉波高度可调的脉波产生器，主要观念在於利用RLC二阶暂态来产生脉波，并利用过阻尼响应来降低脉波尾端的涟波，从模拟与量测中可验证此特性。

A rocky outcropping examined by the rover had ripple patterns and concentrations of salt — considered signs that the rock formed in standing water.

被火星车探测的一块露出地表的岩石有着涟波图案和浓缩盐——这被认为是岩石是在死水中形成的迹象。

The comparisons show the present model are in agreement with available theories and experiments.In particular, the model is further applied to investigate the wave reflection properties of regular waves propagating over sinusoidal topography on sloping beaches.

此外本文探讨 Booij's ramp (1983)不同坡度底床地形及欧等人(2007)沙涟试验造成反射波之反射率，结果显示於适当坡度范围内本文模式可呈现优於传统缓坡方程式计算结果并与试验结果相近。

Jun reached down to Key's shoulder, and she knew that the bleak thrum she felt ripple under her touch was the dying signature of his breaking heart.

六月伸手拿下到钥匙的肩，而且她知道，她感觉在她的触觉下面的涟波萧瑟的织边是他伤心的垂死签字。

The water rippled on, with a pleasant sound; the trees rustled in the light wind that murmured among their leaves; the birds sang upon the boughs; and the lark carolled on high her welcome to the morning.

水面涟波欢唱，林中树叶随轻风飒飒作响，树枝上鸟儿欢鸣，天空中云雀欢歌迎清晨。

Joseph rattled some fire into the shovel, and went; but he brought it back immediately, with the supper tray in his other hand, explaining that Mr Heathcliff was going to bed, and he wanted nothing to eat till morning.

炉火已经烧成灰烬；屋子里充满了阴天晚上的潮湿温和的空气；如此静，不止是吉默吞那边流水淙淙可以很清楚地听到，就连它的涟波潺潺，以及它冲过小石子上或穿过那些它不能淹没的大石头中间的汩汩声也听得见。

Then black churning water, calming back to wind-swept ripples.

然后黑色的搅乳水，向后地平静到风清扫的涟波。

The output ripple voltage is verified so little that no low-pass filter is needed.

在此，我们已证明输出涟波电压非常的小，所以此系统不需要低通滤波器来滤除涟波电压。

Ripple current should be kept below 15%.

涟波电流应被保持在15%以下。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
