查询词典 off and

While laybacking up the lower section of the crack, I concentrated on conserving my energy by climbing as fluidly and in as relaxed a manner as possible. I felt surprisingly strong through the first series of difficult moves, but as I began to execute one of the last ones, my timing and body position were slightly off. As I tried to thrust my finger tips into a small undercling slot, my foot popped off and I suddenly found myself dangling 2000 feet above the ground.

在裂隙下面部份要layback上时，我专注的尽量流畅和用放松的方法来节省体力，我觉得自己好像惊人的强壮爬完第一个连续难点，但当开始爬最后一个时，我的步调及动作有点不配合，我试著强把指尖放进一个小倒拉缝时，脚砰的滑掉，突然觉得自己在距地面二千英呎的地方摆荡。

After the cut-off frequency has been determined, the active noise-filtered system can be designed with several circuits to filter out those frequencies higher than the cut-off frequency and reserve the speech voice only. Besides, the music signals from the MP3 or a CD player can also be transmitted to the earplug system for increasing the signal noise ratio. The anxiety and tension of patients during treatments can, thus, be relaxed due to the euphonious music and toothaches of the patient might be further reduced.

本研究首先以离线的方式收集各类牙科噪音，然后将它传递到个人电脑，并使用CoolEdit及LabVIEW软体程式，分析出在牙科治疗过程中所产生之噪音的频率范围，最后透过各种比较，找出适当的截止频率，在截止频率(1KHz)被决定之后；针对该截止频率，使用主动式滤波的方式设计出相关的电路，组成主动式噪音率除系统，来滤除那些高於截止频率的噪音信号，只保留语音频率范围；此外透过mp3或cd player所播放出的音乐讯号，也可以同时被传递到耳塞系统来增加信号杂讯比，那麼当病人在治疗时，因为有这音乐可以使病人的焦虑跟紧张获得舒缓。

The vertical distribution of Aeolian sand current Based on the distribution function of lift-off velocity of saltating sand grain, this thesis develops a vertical distribution model of Aeolian flow linking with the number of lift-off sand grains percent time percent sand area. The thesis realizes the combination of microcosmic researches and macroscopical researches of Aeolian wind sand and solves primarily the isjunction of microcosmic researches and macroscopical researches.
