芳基化作用 的英文怎麼說
中文拼音 [fāngjīhuàzuòyòng]
芳基化作用
英文
arylation-
Strip - shape underground structures such as the tunnels and tubes for various uses can be treated as a beam on elastic foundation under earthquake condition ， although there exists soil - structure interaction ， the foundation soil vibration is dominant in other words ， analysis of earthquake response of the soil is essential to this end ， simplified models ， ( i. e equivalent mass system models based on some equivalence criteria ) are proposed ， instead of a general 3 - d continuum model in this study ， equivalence criteria are proposed and the simplified models are compared the single - mass - string model is proved to be valid and therefore applied to the analysis of earthquake response of the pearl river immersed tunnel
條裝地下結構如隧道、各種埋設管道等一般可看作彈性地基梁進行靜力及動力分析在地震條件下，結構與土相互作用，但土的振動成為主要因素為分析土的地震響應需把基土這一三維連續體作簡化處理，簡化成為等效多質點模型本文著重探討這種簡化模型的建立方法，推導等效方程，通過幾種簡化體系的分析比較，論證單質點串體系的合理性，並將其應用到廣州黃沙芳村珠江水下隧道工程的地震響應分析，為抗震設計提供依據Uses : used as desizing agent and bleach activator ； used in the oxidation and degradation of waste materials in pools and the closed and circling water ； used in modification of starch, production of bonds and coating materials ； used in the oxidation of alcohol and linalool ； used as an essential component of bleaching formulations for hair cosmetics
用途：用於脫漿劑和漂白活性劑；用於水池及封閉循環處理水中有害物質的氧化降解；是生產澱粉的調節劑，並應用於粘合劑的塗料生產中；用於支鏈氧化、乙醇和芳香族羥基氧化；染發劑的基本成分之一，起脫色作用。This paper deals with seismic response of a tunnel - soil system immersed tunnel ， as an underground structure ， must be compatible with the deformation of the surrounding soil thus the simplified model for a tunnel - soil system is established through two steps at the first step ， an mdof system is developed for modeling the foundation soil to this end ， dynamic behavior of the foundation soil is analyzed a typical section of the foundation soil simplified as a single mass - spring system on the basis of some equivalent criteria those mass are linked longitudinally by elastic springs to form an mdof system at the second step ， the tunnel is treated as a beam on elastic foundation ; that is ， the tunnel is connected with the soil massed to form a tunnel - soil system this model has been applied to the seismic analysis of huangsha fangcun immersed tunnel across the pearl river in guangzhou design recommendation is proposed on the basis of this analysis
研究沉管隧道在地震條件下整體受力的分析方法分兩步建立計算模型第一步通過分析場地地基土切片的動力特性，根據等效原則將其化為等效單質點體系，然後在縱向用等效彈簧連接而成為多質點體系的地基土計算模型；第二步將隧道看作彈性地基梁與上述多質點體系通過等效彈簧連結而得到土隧道體系的計算模型本文結合廣州黃沙芳村珠江水下隧道工程實例建立了具體的計算模型並對多種不同的約束條件，進行了縱向與橫向地震響應時程分析，為該隧道的抗震設計提供依據It has a sedative function, and can be used in many fields, such as aromatherapy, skin care and cosmetics
