45号钢二次枝晶臂间距与冷却速度的关系

本文利用可控平均冷却速度的单向凝固实验炉测定了４５号钢在不同平均冷却速度下的冷却曲线，由此得到其在凝固期间的平均冷却速度Ｒ，相应地测量了不同平均冷却速度下试样的二次枝晶臂间距Ｓ２，通过回归，得到了如下关系式：Ｓ２＝７２７Ｒ－０．４１，并将引式成功地应用于实际生产中。     

Gelling of alginate fibres

Equipment was developed to measure the time for complete gelling of sodium alginate fibres in calcium chloride solution, taken as the time to achieve maximum tensile strength. The effects of fibre diameter, alginate concentration, alginate composition and calcium chloride concentration on gelling time were investigated. A diffusional model, developed to predict the gelling time, agreed with experimental results except for the effect of calcium ion concentration which was modelled empirically.     

A study on the transient characteristics of a self-regulating Joule-Thomson cryocooler

An experimental and numerical study of transient characteristics for the self-regulating Joule-Thomson (J-T) cryocooler is developed in the present work. The modelling of the bellows control mechanism and the simulation of the cooler system are developed. It is proved by experiment that the most important transient behaviours can be accurately predicted by the present numerical simulation. In order to rectify the instability problem of the bellows controlled J-T cooler, this study also proposes a revised design to improve temperature stability. The revised dual-orifice J-T cooler can effectively reduce the phenomena of unstable temperature and mass flow rate, but sacrifices the expected gas consumption rise by approximately 5 percent. Through experimental evaluation, it becomes obvious that this revised type cooler would be a better design.

本文介绍了一个用Ｔｕｒｂｏ Ｃ语言在ＡＳＴ－２８６机器上实现的计算机辅助数据库设计系统ＣＡＤ＾２Ｂ。该系统提供了人机交互的环境，供设计者进行概念模型设计，并自动完成从概念模型逻辑模型的映射，创建满足规范化要求的关系表。该系统采用的概念模型是引入了事件和时间的扩展了的实体关系模型。该模型既能充分反映应用环境的静态和动态语义，又是向关系模式转化的基础。     

提高铌钽标准液显色反应能力并延长其有效贮存期的分光光度法研究

铌，钽的酒石酸，柠檬酸，草酸铵标准液的显色反应能力及有效贮存期，同铌，钽的原始标准溶液ｐＨ有很大关系，铌酒石酸标准液（原始溶液ｐＨ１．４），其显色反应能力仅在８０％～５０％之间（视放置时间长短而异），但如何采用ｐＨ４．５～５．０的铌酒石酸标准液，其显色反应能力达１００％，即使贮存４４０ｄ后，仍能保持原有的显色反应能力，铌柠檬酸标准液（原始溶液ｐＨ１．２），无论用本法（Ｎｂ－ＢＰＲ－ＣＰＢ法）还是用

Bimanual interference associated with the selection of target locations.

Four experiments were conducted to identify the locus of interference observed during the preparation of bimanual reaching movements. Target locations were specified by color, and the right-hand and left-hand targets could be either the same or a different color. Movements of different amplitudes (Experiment 1) or different directions (Experiment 2) to targets of the same color were initiated more quickly than symmetric movements to targets of different colors. These results indicate that costs observed during bimanual movements arise during target selection rather than during motor programming. Experiments 3 and 4 further examined the interference associated with target selection. Reaction time costs were found with unimanual movements when the target was presented among distractors associated with responses for the other hand. Interference observed during bimanual reaching appears to reflect difficulty in segregating the response rules assigned to each hand.
