Because the skin excretes melanin , which will come out absorb the uv rays from sun and darken the skin , but the hair doesn ' t , it can only decompound melanin 答案一,人體會在皮膚表面增加黑色素的沉積,阻擋陽光中的紫外線深入皮膚內(nèi)層,但是頭發(fā)沒這本事,只會分解黑色素。
Flavour compounds of fermented sausage are formed through carbohydrate fermentation , fat metabolism , nitrogenous compounds decompound and spices . flavour components of fermented sausage and its origins are summarized in this paper 發(fā)酵香腸的風(fēng)味物質(zhì)主要來自于碳水化合物、脂肪、蛋白質(zhì)的代謝和氧化,以及人為添加的香辛料。本文概述了現(xiàn)已鑒定的發(fā)酵香腸的主要風(fēng)味物質(zhì)及來源的研究情況。
Based on the analyses on mechanical properties , microstructure and fracture of - the microalloyed steels socrv with various heat treatment technique , it can be affirmed that various fractures arttribute to various mechanism , we can draw conclusion that the strength and toughness of microalloyed steels 50crv will be increase simultaneously by optimal heat treatment technique . to illustrate the mechanism of the strength and toughness of microalloyed steels socrv , we designed the comparative experiment and observed the microstructure of the sample which occurred at different quench and tempering temperature and different tempering time . the last experiment results were determined by the four factors : fined microalloyed elements grains , the decompound of martensite , martensite transformation of remnant austenite and the second phase precipitation 為解釋微合金化50crv鋼強(qiáng)韌化機(jī)理,本文通過對不同淬火溫度,回火溫度,回火時(shí)間下的力學(xué)性能指標(biāo)的對比及顯微分析,認(rèn)為微合金元素的細(xì)化晶粒,馬氏體的回火分解,殘余奧氏體的轉(zhuǎn)變,第二相的沉淀析出共同決定了微合金鋼的強(qiáng)韌化情況,特別是由于微合金元素的存在,其細(xì)化晶粒及其碳氮化物的沉淀析出,導(dǎo)致鋼的良好的強(qiáng)韌性,并且如果工藝滿足第二相的沉淀析出強(qiáng)化大于回火馬氏體分解引起的軟化效應(yīng),會在硬度曲線中產(chǎn)生明顯的二次硬化現(xiàn)象。
On this base , a pdm software system is worked out , including the mode of organization structure , stuff popedom management , product structure collocation , task decompound , documentation management and read overmar gin alia . at the same time , considering the internationalization and localization of ship design , the mode of distributed design and calculation adopting distributed servers is realized 在此基礎(chǔ)上,我們編制了pdm2001軟件系統(tǒng),其中包括組織結(jié)構(gòu)與人員權(quán)限管理、產(chǎn)品結(jié)構(gòu)配置,任務(wù)分解,文檔管理與批閱等模塊,同時(shí)考慮到船舶設(shè)計(jì)的國際化和區(qū)域化,采用了分布式服務(wù)器,基本實(shí)現(xiàn)了分布式的設(shè)計(jì)計(jì)算模式。
At the begin , we decompound the frame - work to seven class set , which are object class set , interaction class set , model class set , federate - agent class set , simulation class set , interface class set and framework class set , and offer a class - hierarchy structure gragh for it . then , we give the detailed realizing method for each class set in sequence 先把空襲目標(biāo)流邦元分解為7大類集,即對象類集、交互類集、模糊類集、聯(lián)邦成員代理類、仿真類集、界面類集、框架類集,并給出其類層次結(jié)構(gòu)圖,然后對各個類集的具體實(shí)現(xiàn)方法進(jìn)行了詳細(xì)設(shè)計(jì)。
