查询词典 disk signal

The hard disk protection mechanism comprises the following steps: the monitoring program forbids the computer device from data access to the hard disk through a hard disk driver program; and a basic input/output system of the computer device sends out a control signal for the park of the hard disk to the hard disk.

该硬盘保护机制包括有监控程序透过一硬盘驱动程序禁止计算机装置对硬盘做数据的存取、以及由计算机装置的基本输出入系统送出一硬盘归位的控制信号至硬盘。

Because any reports on the active control of rotating disk haven't be seen in China up to now, and this experiment research is important, so the complete set of active control system of rotating disk are built independently. The push-pull type electromagnet is applied to control the vibration of the circular disk. The power amplifier circuit that can respond to wide scope in frequency from DC to AC is designed by improving the existing circuit. The sensor signal is first low-pass filtered, then the proportional control plus the differential control circuit easy used in practice are applied to finish the more effective control. The electromagnetism shield is used as possible to decrease the signal disturbance from the electromagnet to eddy sensor.

考虑到目前国内尚未见到有关旋转圆盘振动主动控制的相关报导以及实验的重要性，自行设计制作了一整套旋转圆盘振动主动控制系统：提出并采用推拉型电磁作动器来控制圆盘的振动；在改进现有电路的基础上，自行设计了具有较理想特性的驱动电磁作动器的功率放大器；根据实际控制环境的特点，设计了先进行低通滤波，再采用比例和实用的近似微分电路构成的控制器，并采用了电磁屏蔽来减小电磁铁对传感器的干扰，以实现更有效的控制。

Since the motherboard with the soft, hard disk, such as the use of DMA operations between the peripheral, DMA operation of the response process is as follows (AST386 in the floppy disk to DMA as an example): floppy disk drive made by DREQ2 signal to the DMA controller (82C206), and DMA controller to the CPU (80386) issued HRQ signal, CPU end the current bus cycle after HLDA response signal to the DMA controller, DMA controller issued a final response signal DMA to the floppy disk drive DACK2 allow its data into the system bus.

由于主板与软、硬盘等外设之间采用DMA操作，DMA操作的应答过程如下(以AST386中软盘DMA为例)：先由软盘驱动器发DREQ2信号给DMA控制器(82C206)，然后DMA控制器向CPU(80386)发HRQ信号，CPU结束当前总线周期后发响应信号HLDA给DMA控制器，最后DMA控制器发DMA响应信号DACK2给软盘驱动器允许其数据进入系统总线。

THESIS ABSTRACT SYSTEM MODELLING AND IMPLEMENTATION OF THE OPTICAL DISK SIGNAL PROCESSOR AND CONTROLLER The design and implementation of the signal processor and controller for the optical disk storage are approached.

本论文是围绕计算机用光盘机的信号处理系统设计与实现展开。作为理论基础，论文较系统地研究了时域、频域建模方法，特别是频域建模方法和精度分析。

And investment that benefits the state has two signal disk may become cause for concern: The first concerns the policies and external, as well as the company shortly after Huijin signal holdings; the second main concern Pupil Fighting 1800 — 2000 points in the end who can win the region, to put it simply is affected破位build the double bottom.

和投资有利于国家有两个信号的磁盘可能成为令人担忧：一是对信号后不久，汇金持有的政策和外部，以及公司，第二个主要关注的瞳孔搏击1800 - 2000年在终点谁可以赢得该地区，简而言之，是影响破位建立双层底。

According to the diffraction theory used in DVD system, we propose a new theory to analyze the RF signal and tracking error signal of Super-RENS disk. Then we use simulate the tracking error signal under beam aberration. Finally we use FDTD method to simulate the tracking error signal at defocus.

我们亦根据传统光碟片的绕射理论，提出一新的架构用於分析此近场结构，并用此理论进行射频及偏轨信号的模拟；接著探讨在有像差产生的情形下，其对偏轨信号的影响，最后用有限时域差分法验证在失焦下，偏轨信号的变化。

An apparatus for balancing and centering a disk comprising a sensor that produces a signal indicative of the disk's deviation from a desired dimension and a movable reference surface that moves the disk in response to the signal from the sensor.

一种用于平衡并对中磁盘的装置，该装置包括产生一种信号的传感器，该信号表示磁盘与理想尺寸的偏差，该装置还包括一移动式基准面，该移动式基准面响应于传感器产生的信号，对磁盘进行移动。

Beside, the DVD-ROM drive use the FE signal to compensate the axial wobble (CD:±500μm, DVD:±300μm) which are caused by the rotating disk. The gain signal of the plant will be corrected during the automatic adjustment procedure when the DVD-ROM drive is starting.

此外，光碟机利用聚焦误差信号来补偿盘片旋转所造成的轴向偏摆(CD：±500um、DVD：±300um)，其信号增益值在光碟机启动时的自动调整程序里进行校正。

Also the board which is setted at personal computer directly access tomemory unit without passing through floppydisk. lt is obvious that this method is, faster than floppy disk owing to entirely electric signal procedure. Ourtherwise, the ROM is eliminated the virus interfere during normal operation.

本卡插於PC上时可在开机后立即将DOS从CARD上载入记忆体内，而不须从磁碟机上载入，由於该卡无机械动作全为电子信号之处理，因此其速度较磁碟机为快，且由於ROM为仅读，故不怕ROM DISK被病毒所侵袭，不怕一开机时即遭到病毒干扰。

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.
