部分 (整體中的局部或個體) part; section; portion 部分禁止核試驗(yàn)條約 treaty on the partial halting of nuclear tests; 我們看問題, 不但要看到部分, 而且要看到全體。 in approaching a problem we should see the whole as well as the parts. 他完成了自己的那部分工作以后, 又去幫助別人。 after finishing his share of the work he went to help the others. 我們部分地改變了原計(jì)劃。 we've altered the original plan to some extent
The mechanism of hydrothermal process has also been studied . under the hydrothermal conditions , a small quantity of cu2 + in solutions were carried to the copper lattice due to the diffusion and convection , then the cu2 + move to the positions of lattice defect . the crystallization reaction happened and copper powders got a good crystallinity and an excellent antioxidation 在穩(wěn)定的水熱條件下,由于擴(kuò)散、對流或強(qiáng)迫流動引起少部分溶解在溶液中的銅離子向銅晶體表面附近的區(qū)域輸運(yùn),在晶面某一位置上被吸附,并通過表面擴(kuò)散,順著臺階運(yùn)動到扭折位置,發(fā)生結(jié)晶反應(yīng)。
At low concentration of zn , the changes in ultrastructure were nuclei deformation , chloroplast swelling and disorder of thylakoid arrangement ; serious damages in ultrastructure caused by greater zn stress were indicated by scattered nucleoli , condensed chromatin , almost empty nuclei with nuclear membrane disrupted and nucleoplasm flowing into cytoplasm , swollen and partly dissolved cristae of mitochondria , disrupted and collapsed chloroplast envelopes , and some dissolved thylakoids that flew into cytoplasm 超微結(jié)構(gòu)的變化也呈現(xiàn)加重趨勢,低濃度處理的變化為細(xì)胞核變形、葉綠體膨脹、類囊體排列紊亂;嚴(yán)重的超微結(jié)構(gòu)的損傷是核仁散開、染色質(zhì)凝集,細(xì)胞核幾乎成為空核和核膜破裂,核質(zhì)散出;線粒體脊突膨脹和部分溶解;葉綠體膜斷裂、消失和部分類囊體溶解和散到細(xì)胞質(zhì)中。
( 4 ) which deformation behavior of cementite lamellae in pearlite colonies is closely related to the stress state of cementite which significantly depends on cementite thickness and orientation , especially on cementite thickness . ( 5 ) the lamellar cementite undergoes partial dissolution on the present deformation . the thermodynamical destability of cementite is attributed to a large number of defect in cementite introduced by severe plastic deformation providing evidence for cementite dissolution 而滲碳體的應(yīng)力狀態(tài)主要是與滲碳體的片層厚度和取向密切相關(guān)的,其中滲碳體的厚度起決定性作用; ( 5 )本實(shí)驗(yàn)變形條件下,滲碳體出現(xiàn)了部分溶解的現(xiàn)象,這是由于強(qiáng)烈塑性變形而在滲碳體中引入大量的缺陷導(dǎo)致其處于高能不穩(wěn)定狀態(tài)從而促使了滲碳體溶解。
