【正文】 ehold decoration, after all, not all tenants wanted to ceiling. ( the building water supply and drainage design specification ) GB15 2020(manuscript ) as 外文翻譯 6 specified in article , water supply pipe should be laid in the floor ( ground ) surface of the leveling layer or along the wall laying pipe groove, laying the leveling layer or the tube groove water supplying pipe outside diameter is less than 25mm. In fact, if connected to two or more than two water points, water supply branch pipe are connected together in series, the pipe diameter is more than 25mm. Therefore, in order to meet the specification requirements, water supply branch door after access water separator, a water segregator dark kitchen or bathroom wall, through the diversion device connected to each water using point branch pipe diameter can be controlled under 25mm. But it should be noted: a leveling layer water supply pipe after pletion of construction, should be in the position to do the obvious markers, lest the household decoration, destruction of water supply pipeline. Skyscraper water gauge the open air set up following severa ⑴ kinds of forms: Whether far it pass by water gauge Change the ordinary water gauge into and pass the water gauge far, is joined the water gauge and data gathering machine by a signal line, And then reach intelligence to manage( the puter). Its merit lies in saving a large amount of people Strength es to check meter, the data are accurate, the shorting is that the fabrication cost is high. Whether ⑵ adopt magic stripe card of by water gauge Users buy the electronic card of the running water Company in advance , then insert it in the storing device of the water gauge, Card amount of money deduct automatically on the water, this way user need to prepay the water rate, The price of the water gauge is relatively high. ⑶ adopt it set up at the open air water gauge not ordinary 1)The water gauge is set up in the stair have a rest in the alcove of the platform. Household watersupply to prop up and manage and enter the kitchen, bathroom after the water gauge is measured. Way this realize water gauge produce room set up, equivalence low project have , supply water and set up and in charge of and set up with water gauge office results in aesthetic problems in stair. It suitable for the South warm district kitchen, bathroom assign close to the houses of positions of staircase. 2)The water gauge concentrates on being set up among the water gauges( meter box). Person who give when supplying water, set up water gauge in ground floor( meter box) on falling, every household watersupply to prop 外文翻譯 7 up and is in charge of applying having in the pipeline well, Southern area can overcast horn place lay along the outer wall in building too。采用單片機(jī)控制使得儀器儀表數(shù)字化、智能化、微型化，且功能比起采用電子或數(shù)字電路更加強(qiáng)大。 ⑶ 在家用電器中的應(yīng)用 可以這樣說，現(xiàn)在的家用電器基本上都采用了單片機(jī)控制，從電飯褒、洗衣機(jī)、電 冰箱、空調(diào)機(jī)、彩電、其他音響視頻器材、再到電子秤量設(shè)備，五花八門，無所不在。 現(xiàn)在可以說單片機(jī)是百花齊放，百家爭鳴的時期，世界上各大芯片制造公司都推出了自己的單片機(jī)，從 8 位、 16 位到 32 位，數(shù)不勝數(shù)，應(yīng)有盡有， 有與主流 C51 系列兼容的，也有不兼容的，但它們各具特色，互成互補(bǔ)，為單片機(jī)的應(yīng)用提供廣闊的天地。所以這種工藝將是今后一段時期單片機(jī)發(fā)展的主要途徑。現(xiàn)在的許多單片機(jī)都具有多種封裝形式，其中 SMD(表面封裝 )越來越受歡迎，使得由單片機(jī)構(gòu)成的系統(tǒng)正朝微型化方向發(fā)展。此外還有 MOTOROLA 公司的產(chǎn)品，日本幾大公司的專用單片機(jī)。由于這些問題的產(chǎn)生，水表出產(chǎn)已成為必然的選擇 。其優(yōu)點(diǎn)為；抄表方便，抄表人員勞動強(qiáng)度低，可以杜絕用戶的 輸水行為。其優(yōu)點(diǎn)為：分戶支管短，較節(jié)約管材，管道水頭損失也較小，缺點(diǎn)是：水表分散設(shè)置，抄表人員勞動強(qiáng)度較大；通常室內(nèi)消火栓箱也明設(shè)于休息平臺處，因而使本來就擁擠的休息平臺更為局促，給住戶通行帶來不便。遠(yuǎn)傳水表計算準(zhǔn)確且無需抄表，此卡表需用戶預(yù)存入一定數(shù)額水費(fèi)，將充值后的 IC 卡插入水表的讀碼器中即可用水。目前，新建住宅外文翻譯 11 中一廚兩衛(wèi)已很普遍，有的住宅甚至配有一廚三衛(wèi)、一廚四衛(wèi)，且廚房、衛(wèi)生間、陽臺各用水點(diǎn)位置均較分散。因此，為了滿足規(guī)范的要求，給水支管入戶后即接入分水器，分水器暗設(shè)于廚房或衛(wèi)生間墻體內(nèi) ，通過分水器后接往各用水點(diǎn)支管管外徑均可控制在 25mm 以下。多層住宅水表戶外設(shè)置有以下幾種形式： ⑴ 采用遠(yuǎn)傳水表把普通水表換成遠(yuǎn)傳水表，由一根信號線連接水表與數(shù)據(jù)采集機(jī)，再傳至智能管理（微機(jī)）。住戶給水支管經(jīng)水表計量后進(jìn)入廚房、衛(wèi)生間。下行上給式供水時，在底層設(shè)水表間（水表箱），各層住戶給水支管在管道井內(nèi)敷設(shè)，南方地區(qū)也可在建筑物陰角處沿外墻敷設(shè)；上行下給式供水時， 可在屋頂設(shè)水表間（水表箱）
