脱碳

The results show that the main reason is many little cracks exist,and heavy reticulation structure,inclusion, coarse grain and side decarburized stucture.

结果表明，其发生断裂的主要原因是存在较多的小发纹，加之较严重网状组织、夹杂物、晶粒粗大和边部脱碳组织，在机械加工力的共同作用下，导致轻轨发生断裂。

The fusing liquid medium heating workpiece, like the nitre salt class, the alkalis, the oil class and the low melting point metal and alloy and so on, the nitre salt furnace heating

熔融液体介质加热工件、如硝盐类、碱类、油类及低熔点金属及合金等，硝盐炉加热工件，加热速度较快，氧化脱碳较轻，便于局部淬火，等温淬火及多种化学热处理。

In China, now the majority of linkage plant is used in billet Kong Qichui system, Steam hammer forming, forging our common link is the size of the problem of poor accuracy, forging surface well, forging the surface decarbonization serious problems.

而我国现在多数连杆生产厂采用的是空气锤制坯，蒸汽锤成形，因此我国连杆锻件普遍存在的问题是尺寸精度差、锻件表面状态不好、锻件表面脱碳严重等问题。

This global decarbonization trend has been proceeding at a remarkably steady rate since 1850, according to Jesse Ausubel of Rockefeller University and Paul Waggoner of the Connecticut Agricultural Experiment Station .

洛克菲勒大学的杰西·奥苏贝尔和康涅狄格州农业试验站的保罗·瓦戈纳的研究表明：自从1850年，全球的脱碳趋向一直在明显而稳步地持续着。

But, it is not perfect, and its anticreeping carbon ability is lower and its later stage of heat-treating equipment needs higher.

但它并不是完美无缺的，它的防脱碳能力差，对后期热处理设备要求较高。

In recent years, Yihua greatly enhanced its self-determined scientific and technological ability for innovation. It implemented over 200 items of new techniques, developed over 20 items of state-level or province-level new products, declared over 100 patents of invention and achieved over 50 items of state-level, province-level or city-level important scientific and technical achievements, among which, the YH Non-break Molding Powder Coal Gasification Technique was for the first in the world applied in mass production device of urea. Yihua%26rsquo;s Technique of Pressure-swing Decarbonization Absorber won a national gold prize for patent of invention. Its Technique of Heavy-medium Ore Beneficiation and Twice Versa Floatation successfully solved the global problem that collophanite could%26rsquo;t be used to produce DAP.

近两年，宜化开发并实施了300多项新技术新工艺，开发了20多项国家级、省级新产品，申报了200多项发明专利，取得了50多项国家、省、市级重大科技成果，具有极强的自主创新能力，其中YH粉煤连续成型气化技术成为世界第一家大规模用于尿素生产的装置；变压吸附脱碳获得了国家发明专利金奖；重介质选矿和双反浮选技术成功地解决了胶磷矿不能生产磷酸二铵的世界难题。

No graphites are found after the hot metal decarbonized by oxidization is cooled.

对铁水进行氧化脱碳处理后进行冷却，没有发现片状石墨析出。

At the bonding temperature of 1373K, four phases of TiC, Ti3Al, FeAl and FeAl2 were established and three layers were formed in the TiAl/40Cr joint, the interface structures were observed as TiAl/ Ti3Al+FeAl+FeAl2/TiC/decarbonized layer/40Cr steel.

研究结果表明，在1373K的接合温度下， TiAl/40Cr接头生成了TiC， Ti3Al， FeAl和FeAl24种反应相，形成了3个反应层，界面结构为TiAl/Ti3Al+FeAl+FeAl2/TiC/脱碳层/40Cr钢。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
