熔合

The complete fusion excitation function for the 16O+24Mg reaction has been measured in the energy range of 55～90MeVwith the step of 1.0MeV using a position sensitive△E-E telescopy system.

本工作用位置灵敏的△E－E望远镜系统，入射能量步长为1.0MeV，测量了55～90MeV~（16）O＋~（24）Mg反应全熔合激发函数。

During the event, Malachor V was turned into a broken cluster of planetoids that were only tenuously fused together by the gravitational anomalies present in the system.

在此事件中，马拉卓5号星被转化为一团破碎的小行星群，仅仅是因为星系中出现的引力异常，而稍微熔合在一起。

The reason lies in unable butt fusion between terne plating of the copper-insert surface and lead-tin alloy used for terminal post.

本文针对阀控式铅酸蓄电池极柱铜芯的松动问题进行了分析讨论，通过试验发现铜芯松动的原因在于铜芯表面的电镀铅锡合金层与柱体浇铸用的铅锡合金不能熔合在一起。

To fuse within themselves its rules precise and delicatesse?

忘记了把艺术的准确而精致的规律熔合在它们之中？

In the fusion zone, the columnar grains range in the direction of heat dissipation on one side of the joint and fine equiaxed grains on the other side.

在熔合区，焊缝一侧为沿散热方向排列的柱状晶，另一侧为细小的等轴晶组织。

When the Al-Mg-Zr-Sc welding wire was used as filling material,the grains of welding seam were refined obviously,and the weld joint was greatly strengthened by forming of fine equiaxial grains layer in fusion zone .

但采用Al-Mg-Zr-Sc合金焊丝为填充材料时，焊缝晶粒组织明显细化，熔合区形成的细小等轴晶层提高了基材与焊缝填充材料的结合力，焊接接头的屈服强度比采用Al-Mg-Zr合金焊丝为填充材料时提高了100 MPa，显著提高了Al-Mg-Sc合金焊接构件的许用强度，因此焊接Al-Mg-Sc板材更宜采用Al-Mg-Sc-Zr焊丝。

Mm. 7.5.3 Requirements for quality of weld joint's surface: a No crack, not fusional, bubble, slag, splash; b Surface of seam of pipeline with design temperature lower than -29℃, stainless steel pipeline and alloy steel pipeline with trend of harden quenching shall be free from undercut.

The surface shall be smooth 7.5.3 焊接接头表面的质量应符合下列要求： 28 SH 3501-2002 a 不得有裂纹，未熔合，气孔，夹渣，飞溅存在； b设计温度低于-29℃的管道，不锈钢和淬硬倾向较大的合金钢管道焊缝表面，不得有咬边现象；其他材质管道焊缝咬边深度不应大于 0.5mm，连续咬边长度不应大于 100mm，且焊缝两侧咬边总长不大于该焊缝全长的 10%； c 焊缝表面不得低于管道表面，焊缝余高Δh 应符合下列要求： 1 100%射线检测焊接接头，其Δh≤1+0.2b1，且不大于 2mm； 2 其余的焊接接头，Δh≤1+0.2b1，且不大于 3mm。

Before installation,it has been discovered that the boiler water-wall pipes with small diameter and large wall-thickness of ultra-supercritical units in second-phase project for Huaneng Yuhuan Power Plant have comparatively serious unfused weld-joint defects,needing to carry out a large amount of inspection.

华能玉环电厂二期超超临界机组锅炉水冷壁小径厚壁管安装前发现焊缝存在较严重的未熔合缺陷，需进行大量检测。

The results show:there are a lot of dislocation martensites,a little of twincrystal martensites,remnant austenites and Cr 23 C 6 compounds.The unsufficient diffusion is the reason of the chemical composition distribution of the fusion zone.The amount of martensites and the formation of microstructure are mainly decided by the chemical composition of the base me...

结果表明，马氏体带含大量位错形马氏体、少量的孪晶形马氏体、残余奥氏体以及Cr23C6 化合物；熔合区化学成分分布特征缘于不充分的扩散传质；马氏体的数量、亚结构特征以及Cr23 C6 化合物的形成取决于母材和填充金属的化学成分。

Nickel-boron alloys form the basis of brazes used to join many nickel-base alloys,especially in aerospace.a eutecytic forms between nickel and nickel boride n and so a nickel boron braze can melt and flow without melting the nickel-base materials to be joined.

镍硼熔合依据镀黄铜过去常常加入许多镍基地合金的形式，特别是以航空航天。a eutecytic形式之间镍和镍硼化物n和镍硼如此镀黄铜可能熔化和流动，无需熔化将被加入的镍基地材料。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
