大排距冲天炉性能分析

为了适应大规模、高效率的生产要求，对普遍冲天炉进行改进，设计出双排、大间距冲天炉。以前延用的是单排、独风口化铁炉，其存在熔化率低、铁水温度低、铁水成分不稳定、工人劳动强度大等缺陷，已不适合现代生产的要求。经改进设计后的冲天炉为双排、多风口，即每排４个风口，一菜８个风口。目的是人为地增加一层氧化一还原带，在炉内形成两个相互分开的燃烧带，使第一还原带的ＣＯ充分燃烧，并与得到充分预热的焦炭迅速发生反应，     

Improvement of Time-Driven Models of Lamina Cocksfoot Digestibility by a Process-Based Model to Take Account of Plant N Nutrition and Defoliation

For management purposes, models of lamina digestibility (D_W) that are thermal time driven (T_sum) fail to account for plant nitrogen status (0 < Ni < 1) and defoliation intensity (residual sheath height: S_r). The objective of this paper was to enrich them using a functional processed-based model, which assumes that the decline in D_W over time depends on the metabolic : structural tissue ratio and plant ageing. An experiment combining two N fertilizer rates and two defoliation regimes (differences in S_r) for two spring and two summer regrowth was done to analyse D_W of laminae (youngest fully expanded) and tiller (whole green lamina) levels. For laminae, we show that both processes contribute to explain the decline in D_W at a rate that depends on Ni but not on S_r. For tillers, consistent results were found justifying the use of a simple model: D_W = f(+Ni; −Ni × T_sum; −S_r). Two different databases (from experiment and commercial farms) were used for validation: RMSD varied from 35 to 49 g kg⁻¹. The process-based model strengthened the empirical model and improved the comprehensiveness of how management practices change D_W. We used both models to create applications for reasoning yield in function of herbage mass in complement than in function of time.     

定向结构板居室室内热环境的研究

运用温湿度自动记录仪对3种不同结构实体建筑的室内垂直空间的温湿度，墙体内外表面温度进行了监测，分析了建筑物的日平均温度变动比、衰减倍数。墙体内外表面以及室内垂直空间的温湿度分布，研究结果表明，内外表面均采用定向结构板，中间填充玻璃棉的复合墙体比传统砖墙的保温隔热性能好，能有效地抵抗外界大气环境对室内热环境影响的作用。

集成材的技术要求和试验方法

我国非结构用集成材尚无统一标准，不同厂家的产品质量要求高低不一，造成珍贵木材资源的浪费和经济效益不佳。以日本集成材标准为基础，结合我国生产实践经验提出的集成材技术要求，有助于克服这一困难。据测算，采用该技术要求可使集成材出材率达到２５％左右。

Effects of the Adaptable Distribution for Lateral Forces Considering modes Coupling on Structural Pushover Analysis

Two high and flexible RC frame structures are analyzed;the paper explains the rise in the structural damping ratio and the base mode's drifting,and the modes coupling is caused by the greatly rising damping ratio.The paper also proposes that the modes coupling need be considered in the pushover analysis of the high and flexible RC frame structures.A CQC adaptive distribution for lateral forces in considering the modes coupling at every load step is given,and is compared with the traditional SRSS one.Meanwhile,some practical engineering suggestions are given.
