This apparatus eliminates the effects of microseisms . 這種儀器排除了微地震的影響。
The theory explains the microseisms are originating from surf or other action at steep coasts . 該理論解釋脈動(dòng)的原因是激浪或陡岸的其它作用。

On this basis , from the enterprise microseism bedding plane , it develops and gives the synthetically study frame about resource , ability , surround environment and compete superiority 在此基礎(chǔ)上,從企業(yè)的微觀層面,推演給出資源、能力、外部環(huán)境、競(jìng)爭(zhēng)優(yōu)勢(shì)整合研究框架。
Water feeding framework takes electromagnetism water valve as administration component and is added relief valve for stabilizing hydraulic pressure ; the system has large , middle and small water valve that changes unlock combination of electromagnetically operated valve , which can get seven different water flux ; if it is necessary , it should adopt microseism water feeding that can make water feeding get stepless timing 3加水機(jī)構(gòu)加水機(jī)構(gòu)采用電磁水閥作為執(zhí)行元件,加入調(diào)壓閥穩(wěn)定水壓,系統(tǒng)共設(shè)大中小三路加水閥,變化電磁閥的開(kāi)啟組合,可以得出7種不同的加水流量,必要時(shí)采用脈動(dòng)加水法,可使加水達(dá)到無(wú)級(jí)調(diào)速。
Secondly , through analyzing the failure instance of electrical connectors in using and testing environment , educed contact fault was a main mode of failure of electrical connectors . on natural working conditions , the main reasons which caused fault of electrical connector were contact stress decreasing , microseism wearing and tearing and surface film growing 而在正常的工作條件下,造成電連接器電接觸失效,即決定電連接器工作壽命的主要原因是接觸壓力減小、微動(dòng)磨損和表面膜層的生長(zhǎng),而影響接觸壓力、微動(dòng)磨損和表面膜層變化的主要因素是環(huán)境振動(dòng)和溫度。
In seismology, a microseism is defined as a faint earth tremor caused by natural phenomena. The term is most commonly used to refer to the dominant background seismic noise signal on Earth, which are mostly composed of Rayleigh waves and caused by water waves in the oceans and lakes.
