solid-borne noise

Because of the advantages, such as high performance, low power consumption and low noise, SSD ( Solid State Disk) based on FLASH media is the idea succedaneum of traditional magnetic disk drive.

固态盘（Solid State Disk，SSD）以闪存作为存储介质，拥有高性能、低功耗、低噪声等诸多优点，是传统磁盘的理想替代品。

This standard may be used for the calibrations of limited temperature diode noise source, solid state noise source and gas discharge noise source. The calibration accuracy for these sources is evaluated to be better than ± 0.1 dB.

本标准用于校准限温二极管噪声源、固态噪声源和气体放电管噪声源，校准精确度优于±0.1dB。

At the same time, the environmental pollution situation is getting more and more serious, for example, air pollution, water pollution, noise pollution, solid waste pollution.

但与此同时，我国的环境污染也越来越严重，大气污染、水环境污染、噪音和固体废弃物污染问题日益突出。

Electromagnetic interference ( EMI) produced by various electric apparatuses and electronic equipments has been another public nuisance following the noise pollution, air pollution, water pollution and solid waste pollution.

各种电气、电子设备的广泛应用所造成的电磁污染，已成为继噪声污染、大气污染、水污染、固体废弃物污染之后的又一大公害。

Electronic non-speed variation, automatic regulation, solid relay control, stable and reliable, long duration and low noise.

电子无级变速自动调温 、 固态继电器控制, 稳定可靠 、 寿命长、噪音低.
