為了提高精密軸承安裝時(shí)的實(shí)際配合精度，必須利用不使精密軸承變形的測量方法和測量工具，對精密軸承的內(nèi)孔和外圓的配合表面尺寸進(jìn)行實(shí)際的精密測量，可將有關(guān)內(nèi)徑和外徑的測量項(xiàng)目全部予以測出，并且對測得數(shù)據(jù)作出分析，以此為據(jù)，精密配作軸與座孔的精密軸承安裝部位的尺寸。在實(shí)際測量所配作的軸與座孔的相應(yīng)尺寸和幾何形狀時(shí)，應(yīng)在與測量精密軸承時(shí)相同的溫度條件下進(jìn)行。為保證有較高的實(shí)際配合效果，軸和座孔與精密軸承相配的表面，其粗糙度應(yīng)盡可能地小。欠熱淬火溫度偏低或冷卻不良則會(huì)在顯微組織中產(chǎn)生超過標(biāo)準(zhǔn)規(guī)定的托氏體組織，稱為欠熱組織，它使硬度下降，耐磨性急劇降低，影響軸承壽命。軟點(diǎn)由于加熱不足，冷卻不良，淬火操作不當(dāng)?shù)仍蛟斐傻妮S承零件表面局部硬度不夠的現(xiàn)象稱為淬火軟點(diǎn)。它象表面脫碳一樣可以造成表面耐磨性和疲勞強(qiáng)度的嚴(yán)重下降。表面脫碳軸承零件在熱處理過程中，如果是在氧化性介質(zhì)中加熱，表面會(huì)發(fā)生氧化作用使零件表面碳的質(zhì)量分?jǐn)?shù)減少，造成表面脫碳。

為了表面好看，可以用膠水在檢修口上粘上磁磚，這樣從外面看不出來，而檢修時(shí)又方便取下磁磚;安放浴缸前先安好下水配件，并做24小時(shí)閉水試驗(yàn)，看各接頭處是否漏水;安放浴缸時(shí)，注意下水口一端要略低于另一端�？客獾囊欢艘缘陀诳績�(nèi)的一端;浴缸的實(shí)際尺寸可能與標(biāo)稱尺寸不完全一致，購買和安裝時(shí)先現(xiàn)場測量一下，并在預(yù)留正常的公差以方便安裝;下水管稍微呈倒s型，這樣可以防止返臭。嵌入式浴缸安裝方法準(zhǔn)備工作我們要預(yù)先根據(jù)衛(wèi)浴間的規(guī)格大小選擇適合的浴缸，切勿看什么產(chǎn)品好看就買回來。
儀器儀表產(chǎn)業(yè)是裝備制造業(yè)的重要組成部分，是的基礎(chǔ)性、戰(zhàn)略性產(chǎn)業(yè)。2012年發(fā)布的《儀器儀表行業(yè)“十二五”發(fā)展規(guī)劃》指出，到2015年，行業(yè)總產(chǎn)值達(dá)到或接近萬億元，年平均增長率為15%左右；同時(shí)，積極培育長三角、重慶以及環(huán)渤海三個(gè)產(chǎn)業(yè)集聚地。受此鼓舞，我國儀器儀表產(chǎn)業(yè)步入發(fā)展的快車道。

與這種企業(yè)蠢蠢欲動(dòng)的擴(kuò)產(chǎn)行為相比，卻是官方和學(xué)界對鋼鐵產(chǎn)業(yè)前景的擔(dān)憂。鋼鐵市場產(chǎn)能明顯過剩，這已經(jīng)是不爭的事實(shí)。而且目前在龐大的基數(shù)上連年保持了超過3%的增長。即便是在干預(yù)下的25年，鋼產(chǎn)量也達(dá)到了3.49億噸，同比增長了24.6%，增加了近7萬噸粗鋼，而后者相當(dāng)于橫跨歐洲、亞洲和美洲的世界頭號鋼鐵企業(yè)米塔爾公司的全年總產(chǎn)量。鋼產(chǎn)量已經(jīng)占到全世界鋼產(chǎn)量的3%，并且比第四的總和還要多。
