Laser induced resonant fluorescence, sensitized fluorescence and laser "burn through" techniques have been used to study the electron collision rates in a well diagnosed helium plasma, with electron density ne = 5 × 1014cm-3 and electron temperature Te = 1.1eV, for excited states in neutral helium.

在电子密度5×10~(14)cm~(-3),电子温度1.1eV的氦等离子体中,用激光共振荧光,敏化荧光和激光“烧通”三种光谱技术,研究了电子与激态氦原子的碰撞速率.并与以文献上沿用的电子碰撞速率为基础的氦原子的多能级碰撞和辐射模型的计算进行了比较,发现该模型在很大程度上不能预言此类等离子体的特性.实验结果表明,氦原子激态间的电子碰撞转移速率的实际值远比理论值低.

The article introduces 6 portable indirect automatic welding processes with backing,At pre sent,such welding processes are being widely and effectively used at home and abroad. Although each of them has own backing principle and structure,all of them can satisfy with following conditions: 1.good weld appearance on opposite side;2.burn through prevented;3.close attachment with another side of bevel;4.unchanged shape of the backing. The methods for installating and fixing the backing are:1.utilizing the weight of steel plate and compressing tightly:2.using oblique wedge and jig:3.using sprial clamp and magnetic device:4.welding the backing directly to the another side of bevel.

本文介绍了六种目前国内外应用最广泛、收效较大的简易衬垫单面自动焊工艺。各种工艺的衬垫原理、结构各不同,但都能满足以下条件:1.能使反面焊缝成型良好;2.防止焊穿;3.与坡口反面的贴紧程度良好;4.能保持衬垫形状不变。其安装和固定衬垫的方法有:1.利用钢板本身的重量(压紧);2。用斜楔(定位焊)和夹马;3.使用螺旋夹具;4.使用磁铁装置;5.直接把衬垫焊到钢板坡口反面。

Through the investigation on the destruction of the hot blast stoves of a 100 m~3 blast furnace, itis clear that the damage of 4 hot stoves in Bayi Steelworks is mainly due to the large amount ofdusting powder cantaining alkali metals and Fe_2O_3 entrained in the gas and blast and the high blasttemperature above 1300℃, which cause the slagging of the sprung arch of the stove and the chec-ker bricks. and the structure components of the stove grates and pillars, are wrecked under oxida-tion——reduction reaction,...

Through the investigation on the destruction of the hot blast stoves of a 100 m~3 blast furnace, itis clear that the damage of 4 hot stoves in Bayi Steelworks is mainly due to the large amount ofdusting powder cantaining alkali metals and Fe_2O_3 entrained in the gas and blast and the high blasttemperature above 1300℃, which cause the slagging of the sprung arch of the stove and the chec-ker bricks. and the structure components of the stove grates and pillars, are wrecked under oxida-tion——reduction reaction, fail to stand up to the concentrated stresses from all directions at la-sting high temperature and eventually come to a burning-through and/or bending deformation.

通过对新疆八一钢铁总厂100m~3高炉热风炉的破损调查,指出该厂热风炉烧损的主要原因是由于煤气带入大量含碱的金属及Fe_2O_3粉尘,又加之风温高过1300℃以上,致使热风炉拱顶,格子砖渣化,炉蓖和支柱也由于氧化-还原反应,使其组成结构遭到破坏,因而承受不住长期高温下的各向应力集中而熔穿和弯曲变形。
