For example, the roll elastic deformation breaks the statically determinate condition of roll system in duo mill, and this is the main reason of bearing longevity shortening and burning accident; in aluminium foil four-high mill roll system with a 1 mm gap, the ideal position kept by a 3 mm offset is out of effect, some phenomenon such as chock horizontal vibration, gyroscopic effect and micro dimensional dynamic cross happen in fact rolling process, abnormal super and partial load resulted by these is the main reason of the end thrust bearing accident; the thermal deformation of mill roll system accompanying the temperature raising not only changes the roller track age of rolling bearing, but also results a micro dimensional slow dynamic inverse cross that counteracts the gyroscopic effect in a degree.

如二辊高刚度轧机轧辊的弹性弯曲微尺度行为,破坏了辊系机构杆系的静定条件,成为轧机轴承短寿烧损的主要根源;铝箔四辊轧机只具有1mm的有隙辊系,凭借设置3mm偏移距和轧制力平衡产生的水平力以保持轧辊理想定位失去效用,却发生轴承座水平振动现象、陀螺效应和动态交叉微尺度行为,成为止推滚动轴承异常超偏载导致短寿烧损的主要根源;轧机辊系的伴随升温产生的热变形,不仅改变了滚动轴承滚道轮廓,还引起运动副内慢变动态反交叉微尺度行为,抵消陀螺效应的部分动态交叉角度。

在现有的水平状态下钻柱屈曲研究中,一般把钻柱看作均匀的等直径杆,认为钻柱在其自重的作用下,紧贴下井壁,因而通常把水平状态下的钻柱简化为在整个长度上受到井壁均匀支承的轴向受压的简支梁。

Combine with the analysis of the effect that caused by the shielding of topography and the conditions when lightning occurred on the top of the transmission tower, this paper bring forward a synthetical scheme that on the AnNan overhead transmission line, can use long life resistance reducer to reduce the ground resistance of the transmission tower,set up a shielding pull- line on the body of some tower,set up lightning arrester and take unbalance insulated method to improve the level of the line's ability of preventing lightning.

结合地面屏蔽效果分析和雷击杆塔塔顶情况分析,提出了在安南线采用降低杆塔冲击接地电阻、对部分杆塔塔身安装防雷拉线、加装线路避雷器、在双回路共架杆段采用不平衡绝缘配置等措施来提高安南线耐雷水平的综合方案。使用长效降阻剂,降低杆塔的接地电阻,这是提高线路耐雷水平、降低雷击跳闸率的有效措施。

All steel framed structures shall be designed as "rigid frame"(AISC Specification Type 1) or "simple" space frames (AISC Specification Type 2), utilizing single-span beam systems, vertical diagonal bracing at main column lines and horizontal bracing at the roof and major floor levels.

所有的钢框架结构应该设计成"钢架"或者"简易的"空间框架,采用单跨梁系统,在柱杆线上使用对顶撑杆并在顶部和主要的楼板平面上使用水平联条。

A hypothetical drained cell model retrofitted from a 160kA Hall-Heroult cell was set up to calculate the current distribution in the cathode when the anode bottom and cathode top surfaces were declivous. Two half anode-cathode slice thermo-electrical models with the collector bars installed slopingly or horizontally were adopted to calculate the potential drop and electricity distribution of the cathode.

摘 要:将某厂现有的160kA Hall-Heroult铝电解槽改造成导流槽后,在阴极上表面和阳极底面呈斜坡状的条件下,计算了采用不同阴极导杆安装方式时阴极的电位和电流分布,即通过建立导流槽内部从阳极到阴极的一个半切片电热场模型,用有限元法分别对水平和平行于阴极斜坡两种不同导流槽阴极导杆的安装方式下阴极电位和表面电流密度分布进行了计算。

We demonstrated that recombinant baculovirus vectors expressing p35 (Ac-CMV-p35) and eGFP could be transduced into human kidney 293 cells efficiently. The level of transgene expression was viral dose dependent and high-level expression of the target gene could be achieved under the heterogonous promoter.

本研究证明重组杆状病毒载体Ac-CMV-p35和Ac-CMV-GFP能有效地转导人胚肾293细胞,并介导外源基因高效表达,目的基因的表达水平与杆状病毒的感染剂量成正线性相关。

Two half anode cathode slice thermo electrical models with the collector bars installed slopingly or horizontally were adopted to calculate the potential drop and electricity distribution of the cathode .

结果表明,不同的阴极导杆安装方法对导流槽阴极的总电位降大小没有明显影响,但是水平阴极导杆安装更有利于阴极表面电流密度的均匀分布。
