Tianjin iron steel company ltd . , tianjin , china , decided to convert their two existing 300 tpd coal dust fired maerz lime shaft kilns to converter gas firing and placed the corresponding order with maerz 现有的麦尔兹窑是圆筒形的，其每个窑筒的燃烧区截面积为7 . 1 m2 。
For shape optimization of truss structure , the design variables are separated into two kinds of bar sectional size and nodal position by multilevel decomposition optimization method 对于桁架结构形状优化，应用层次分解优化方法，将设计变量分成杆件截面积和节点位置两类变量。
The essence of stealth technique is reducing rcs in different fields using corresponding methods in order to achieve stealthy aim ; whereas achieve anti - stealthy aim 雷达隐身技术的本质是从不同领域用相应的方法来减少目标反射截面积，从而达到隐身的目的；反之是达到反隐身的目的。
Only a fundamental model for infrared radiation and radar cross section of bomber is needed at this stage because the software needs a kind of expansion by users . 2 由于软件最终还需要用户进行扩充，在现阶段对于轰炸机红外目标辐射模型与雷达散射截面积模型只需采用简单的形式。
It is concluded that the combustion chamber passage area , passage direction , passage shape and passage position have a strong effect on in - cylinder current motion and flow speed 计算结果表明，燃烧室通道截面积、通道倾角、通道形状、通道布置对气流运动的形式及气流速度均有较大的影响。
The numerical examples prove that the global optimum can be gained . in addition , ga is applied to ( 0 , 1 ) programming topology optimization of truss , when the cross sections 还将本文算法应用于杆截面积固定的（ 0 ， 1 ）规划拓扑优化问题，算例的结果表明遗传算法能够很方便地处理这类问题。
Consequently , the metal interconnects of vlsi have smaller sectional area and carry increasing power density , which made the electromigration become one of the main latent damage modes 作为vlsi互连线的金属薄膜的截面积越来越小，其承受的功率密度急剧增加，使得电迁移成为电路的主要失效模式之一。
Exhaust carrying sulfur oxides and powders enter the venturi scrubber to interact with the recovery solvent . when passing through the neck , the section surface constricts and the 含硫氧化物及粉尘废气自顶部进入文氏洗涤塔和洗涤液接触流经喉部，由于截面积缩小，高速气体将洗涤液喷成雾状，而达到惯性冲击去除粒状物的目的。
This study analyses the differences in the relative cross - sectional area ( rcsa ) of several cervical extensor muscles , assessed by magnetic resonance imaging ( mri ) , between patients with chronic tension - type headache ( ctth ) and healthy controls 该研究运用mri评价慢性紧张型头痛患者和健康对照者颈部伸肌的横截面积的差异。
This paper discusses the parameters of the simulation result , which have effected the leakage current and potential variation distribution , and provides a theorectic basis for the system design 根据规程的要求，提出了一种排流网钢筋总截面积的计算方法，并结合深圳地铁1号线的数据进行了分析计算，为系统设计提供了理论依据。
