Dividing the main body of this article into three sections, i mainly discuss the economical life span of the equipment of oil field ground in the first section, and heavy repair in the second section
並依據課題研究的特點，將文章的主體分為三大部分，即關于油田地面工程設備經濟壽命、大修理和設備更新的經濟評價方法研究三部分。 -
The realization of this scheme not only can improve the working and living condition on the platform but also can prolong its operational life span. this is bond to bring huge economic profit to offshore engineering, so it has a promising future. to validate the effectiveness of this vibration control method experimentally, a real control system is made to control the vibration of an oil platform model under simulated wave loadings and the experiment will be conducted in the next term
根據理論分析結果，本文後面又針對一個近海平臺的實驗模型給出了該模型在模擬波浪載荷作用下的振動控制系統設計方案，並進行了系統設計，用於將來的實驗模型振動控制實驗，以驗證文中所設計變剛度調諧質量阻尼器對由波浪載荷引起的平臺振動的控制效果。 -
Effects of heated cooking oil products on drosophila melanogaster ' s life span
食用油及其加熱產物對果蠅壽命的影響 -
The third one describes the properties of working fluid and some experiments on viscous - temperature curves of silicone oil, named as 0. 017m2 / s, 0. 027m2 / s and 0. 037m2 / s. the experimental results demonstrate that the dimension of plate and properties of working fluid have influences on life - span and torque transfer performance of lvc. in chapter four, the strength of each component of lvc were designed and corrected and the new seals were used and the space between the inner and outer plate is 0. 4mm
第一章主要說明了課題研究的背景和意義、液體粘性聯軸器的工作原理及其在工程上的應用，介紹了常時四輪驅動汽車的概念與分類；第二章在閱讀大量文獻的基礎上，對液體粘性聯軸器的研究成果進行總結，包括粘性聯軸器的扭矩計算，扭矩輸出所受的影響因素，駝峰發生的機理、駝峰觸發的溫度、駝峰發生時的最小轉速差，聯軸器在發生駝峰現象之前硅油剪切的內部溫度特性，聯軸器的傳熱模型以及汽車速度、滑移率對轉速差的影響。
