Under the scanning electron microscope , for the first time we compare and study both the coalified tracheids through chemical maceration and permineralized tracheid lumen casts. This method reveals the microstructures of wall and perforations of G-type tracheids: 1 The lignified layer of secondary wall is composed of uneven material and further divided into S〓, S〓, S〓 layers; with the smooth enclosing wall, the perforation is internally dumbbell-shaped; 2 In Huia gracilis, the enclosing wall of tracheidal perforation contracts and possesses secondary perforations. The perforation has thickened border facing the tracheid lumen.

本文首次在扫描电子显微镜下对比研究经化学浸解获得的碳质管胞和矿化的管胞腔铸体，明确揭示出了G-型管胞壁层和穿孔的显微结构：1）Hsüa reflexa次生壁木质化层的组成不均一，分为S〓、S〓和S〓层；穿孔腔为哑铃形，腔壁光滑；2）Huia gracilis的穿孔腔收缩，腔壁上发育次级穿孔，孔口具有边缘加厚。

Base on the weldability tests , the repair welding procedures of weari-resistant cast steel (abrasion-plates) have been made up , The results show that satisfying repair welding quality can be attained with such welding conditions as the low hydrogenous alkalescent welding rod , preheating and slow cooling , strictly maint.

通过对其焊接性能的试验研究，制定了该类铸钢件的补焊工艺：低氢型碱性焊条，预热与缓冷相结合的工艺措施，严格控制层间温度(250～300℃)及焊接工艺规范，可获得满意的修复质量。

Common-and air-cushion type comparison: when it comes to air cushion layer, air cushion layer is in a State of managers'change granula, it is made of synthetic elastomer and is indicated by a particle, microparticulate, interlamination of air compression layer by air cushion rubber compounds bubble and decided that blanket surface treatment is divided into three, the first coated paper: use sulfuration to form the process of polishing.

普通型与气垫型对比：谈到气垫层，气垫层是处于封闭式颗粒之状态，它由合成弹性体和微粒组成，微粒内含空气，层间的压缩性由气垫层气泡和橡胶化合物决定，橡皮布表面处理分为三种，第一种涂铸：使用硫化纸张形成表面抛光的过程。

A general problem in protecting the casting ingots by using expanded complex mould casting mold powder is the surface defect that slag deposition can be evolved easily in ingots head.

使用膨胀型复合模铸保护渣保护浇注钢锭，普遍存在的一个问题是容易使钢锭产生头部积渣这一表面缺陷。

The new mold adopts the plane section instead of the funnel section of H^2 mold bottom, and shorten the length from 2100 mm to 900 mm. By simulating and optimizing the slab stress in molds, a new shape-funnel mold is designed, which have merits of lower slab stress and strain and smooth-transition of curve surfaces.

这种漏斗型结晶器将H^2，结晶器下部的漏斗区改为平面区，结晶器漏斗区高度由2100mm缩短为900mm，并通过模拟计算和优化设计，使结晶器内腔曲面形状各部分平滑过渡，使其具有生产铸坯承受变形应力小的优点。

It can suit different inlet temperature and different transter speed.

四段炉型进行三段控制，设有26个温度控制区进行上、下供热，可适应铸坯的不同入炉温度与运行速度的加热要求。
