减薄

The hot air furnace is a kind of energy conservation type furnace, composed of burner, furnace chamber, mixing room, hot air outlet and outside jacket, the diluted air in the jacket has two functions, firstly, having insulation purpose: the air belongs to inert gas, it has good insulation function for furnace body, can reach to purpose to cool/protect inside lining and reduce its thickness of furnace chamber; secondly, having preheating function: the gas in the jacket is contacted with hige temperature furnace wall, and enters the mixing room after heat absorption, then to teach the purpose of preheating and energy conservation.

热风炉由燃烧器、炉膛、混合室、热风出口和外夹套构成，是一种节能型炉型，夹套中的稀释空气有两种作用，其一，保温作用：空气属惰性气体类，对炉体有良好的保温作用，达到冷却保护和减薄炉膛内衬的目的；其二，预热作用：气体在夹套中与高温炉壁相接触，吸热后进入混合室，达到了预热节能的目的。

The simulation results show that the rod baffles placed vertically and horizontally in the unit duct continuously shear and comminute the streamlines of the flow when the fluid crosses over the rod-baffles, change the fluid flow directions, and result in the disruption of the continuity and stability of the fluid. The disturbing flow can promote the fluid turbulent intensity and effectively enhance the heat transfer.

结果表明，纵横交错布置的折流杆在单元流道中不断分割和剪切流道内流体，其扰流作用促进了流体湍流，减薄了液体边界层，减小了对流换热热阻，因而有效地提高了流体的对流换热强度。

Through the study of metallographic specimen and the inclusions through electrolyzation under SEM, it is indicated that the Ti-deoxidized products are globular compound inclusions with the size of 1~3μm in this experiment condition. With the technical of ion beam thinner the inner structure of these inclusions can be observed, whose core is Ti-O and outer is Mn-S. Based on EBSD the phase composition has been analyzed and it indicated that these globular compound inclusions are Ti2O3 and MnS with nucleating center Ti2O3, which can prompt to nucleate IGF.

It is thus possible to prevent a thinning phenomenon in which a gate oxide film is made thin.

因此可以防止使栅极氧化膜变薄的减薄现象。

The material for formation of the granitoids isderived from mixing sources of crust and mantle, with decreasing in crust-derived componentsfrom early to late.5. The tectonic setting for formation of the Mesozoic granitoids in the region isdefined as a post-collisional setting. The occurrence of a small part of rocks with characteristics ofcollisional or anorogenic granitoids provides evidence for the continuous process oftransformation of tectonic regime from collisional through post-collisional to anorogenic.6. Themultiple cycles of mantle-derived magma underplating caused by the multiple stages oflithospheric thinning in the Mesozoic result in the partial melting of middle to lower crust orcrust-mantle syntexis to form magmas. The crystallization of these magmas emplacing afterfractionation is responsible for the formation of the Mesozoic granitoids in this region.

形成花岗岩类的成岩物质来自壳幔混源。5、河南省西部地区中生代花岗岩类成岩构造环境为碰撞后环境，部分岩石具有碰撞期或非造山期花岗岩的某些特征，表明碰撞后阶段既是碰撞造山过程的延续，又是向非造山环境的构造转换时期，因而其岩浆活动在一定程度上仍然继承了碰撞前消减时期和碰撞时期已经活化的岩浆源区性质。6、研究表明，区内中生代多阶段的岩石圈减薄作用引发多旋回的幔源岩浆底侵以及中下地壳的部分熔融或壳幔同熔，由此形成的岩浆经分异演化后侵位可以形成区内的中生代花岗岩类。

Kalamaili suture zone is an important plate boundary in north Xinjiang, and there are plenty of Neopaleozoic volcanic rocks around itThese volcanic rocks are enriched in LILEs and relatively depleted in HFSEs, and they are also characterized by high Nb, Zr, TiO2 contents and Zr/Y, Nb/Y ratios, and depleted SrNd isotopesThe characteristics of these volcanic rocks suggest that they were produced in postcollisional periodThe postcollisional volcanic rocks around Kalamaili suture zone become younger from west to east, which indicates that this suture zone entered postcollisional period gradually from west to east, and reflects that the Kalamaili Ocean had been closed gradually from west to eastAs to the Kalamaili suture zone in postcollisional period, the lithosphere extended and thinned, and the asthenosphere materials upwelled and melted partially, and intensive mantle convection occurred, leading to a plenty of mantlederived magmas underplating the suture zoneThe lithospheric mantle metasomatized by fluid in subduction period melted partially under decompression and high temperature, the resulting melts contaminated the underplating asthenospheric materials, and the erupted lavas became the Neopaleozoic postcollisional volcanic rocks

卡拉麦里缝合带是北疆的一条重要界线，沿该带广泛发育晚古生代火山岩。这些火山岩具有LILE相对富集、HFSE相对亏损的特征，且具有较高的Nb、Zr、TiO2含量和Zr/Y、Nb/Y比值，SrNd同位素主要表现出亏损的特征。综合分析表明，这些火山岩形成于后碰撞期。对卡拉麦里缝合带而言，从西向东后碰撞火山岩的时代逐渐变新，表明该缝合带从西向东逐渐演化进入后碰撞期，这从侧面反映了卡拉麦里洋盆是从西向东逐渐关闭的。对卡拉麦里缝合带而言，在后碰撞期，岩石圈伸展减薄，软流圈地幔物质上涌并发生部分熔融，加上地幔对流作用强烈，使得缝合带下产生了大规模的幔源岩浆底垫；先前在洋壳消减期被流体交代提取过的岩石圈地幔也在低压高温下发生部分熔融，形成的熔体混染了底垫的软流圈物质并喷发，形成了晚古生代的后碰撞期火山岩。
