sound generator 中文意思是什麼
sound generator
解釋
發聲器-
The basic characteristics of the current data network are point - to - point, connectless, doing one ' s endeavor, no quality of service, etc. these characteristics do not meet the requirement of real - time services, therefore, the realization of voip need support of the some key technology. these technologies includes : speech sound coding and data compression, real - time transmission and control, mute compression and multicast, acoustic - echo cancellation and comfort noise generator, dynamic monitor and guarantee of quality of network service, as well as, the compatible of different network and different protocol with each other
但現有的數據網路的基本特性：點對點的、無連接的、盡力而為的、沒有服務質量保證等特性並不適合與實時的業務要求，因此voip的實現需要一些關鍵技術的支持，這些技術包括：語音編碼和壓縮技術、實時傳輸和控制技術、組播技術、靜音壓縮和舒適噪聲生成技術、回聲消除技術、網路服務質量的動態監測和保證技術、以及不同的網路、不同的協議之間的互連互通等等。 -
This paper discusses in detail some problems about scanning sound intensify mearusing system of the pc machine from perspectives of both hardware and software. it puts emphasis on analyzing and working out problem of multicenter data sampling in phase fifo amortize arbitrarness waveform generator this paper makes a deep discussion on the computer exteral interface technology which is developing in high speed. it analyses scanning sound intensify mearusing system interface technology on the basis of isa pci, and introduce the promising idea about designing mearusing system of scanning sound intensity by using usb interface
本文針對快速發展的計算機外部介面技術進行了較深入的探討，分析了基於isa總線、 pci局部總線的掃描聲強測試系統介面技術，並提出採用usb介面的聲強數據採集與處理系統的設計思想，同時對windows底層進行了詳盡的分析，採用vtoolsd 、 vc + + 、 ddk編制的掃描聲強測試系統驅動程序，運行在系統核心（ 0級環） ，並能與windows很好的協作運行，既能體現windows的多任務操作系統的特點，又保證了數據可靠、實時的採集。 -
To ensure an uninterrupted operation of communications facilities such as the exchange, we normally use the diesel generator engine unit ( dgeu ) as the backup power. once there is a break in municipal power pipes, dgeu is immediately brought into operation through ats to feed communications facilities, thus guaranteeing a sound offering of telecom services
為保證交換機等通信設備的不間斷運行，一般多採用柴油發電機組做為自己的備用電源，一旦市電發生供電故障，即刻啟動柴油發電機組，通過市電油機轉換屏（ ats ）進行切換，由柴油發電機組對通信設備提供電源，以保障電信業務的正常運行。 -
One is a stimulus generator and the other is a data acquisition system. the stimulus generator is the core we introduce. it is also the crux of the whole system which attributes to the expanded function and flexibility. in this design we take the lead in applying the technology of dds to sound stimulus generator, which not only simplifies the hardware, but enhances it ' s flexibility
其中刺激器設計部分是介紹的核心，是整套系統功能擴展及刺激靈活性得以實現的關鍵，本設計率先將通信中的直接頻率合成技術引入到該產品的開發中來，該項技術的引入不但使硬體電路設計大為簡化，而且增強了刺激控制的靈活性，使刺激模式也得以增加。 -
Most present acoustic level gauges use a sound generator which can produce high - power acoustic waves and a microphone which can detect the echo signal. the fluid level can be worked out based on the artificial analysis of the echo curve
目前正在應用的井下液位測量儀器，主要是通過爆炸聲源產生大功率聲脈沖信號，利用微音器接收回波信號，人為地對回波信號曲線進行分析來估算液位。
