添加复合粘结剂的球团试验

对复合粘结剂与无机膨润土粘结剂进行了球团对比试验。试验结果表明，复合粘结剂的成球性能远远优于无机膨润土的，可大幅度降低粘结剂配比(由2．5％降低至0．6％～1．0％)，提高球团矿品位(球团矿品位上升0．8％～1．0％)。配加复合粘结剂的生球爆裂温度和成品球强度指标均有下降，但这些指标都能满足球团生产和高炉冶炼要求。     

A preparation method for observing intracellular structures by scanning electron microscopy

In order to observe intracellular structures by scanning electron microscopy, excess cytoplasmic matrix must be removed from the fractured surface of cells. Previously we reported an Osmium-DMSO-Osmium method devised for this purpose. This method is very effective in revealing intracellular structures, but requires osmium tetroxide for initial fixation with some consequent disadvantages. In the present study, a revised Osmium-DMSO-Osmium method is reported, in which an aldehyde mixture is used as the initial fixative instead of osmium tetroxide. As fixation is carried out by perfusion in this revised method, better preservation of fine structures is achieved than by the original method, especially in the central nervous tissue which tends to suffer from post-mortem degeneration. Moreover this method can be applied to cytochemical studies of intracellular structures with a scanning electron microscope (SEM). In this study, acid phosphatase of lysosomes is demonstrated in a coloured SEM micrograph.     

摆线轮齿形的组合修正方式及其优化设计

针对齿形已经确定的摆线轮,在修正方式及修正量未知的情况下,利用改进的复合形法对摆线轮齿形修正方式及修正量进行了优化分析．同时,采用工艺过程简单的“等距＋ 移距” 修正方式代替工艺过程较复杂的转角修正方式,使用该方法计算等距和移距修正量速度快,与传统的计算方法相比较,工作效率明显提高．计算结果表明：在摆线轮齿形的各种修正方式中,“正等距＋ 负移距”修正方式是较理想的摆线轮齿形修正方式．这种修正方式具有理想齿形,加工工艺简单,在设计与制造中有一定的推广使用价值

Vapor Species over Na2O-B2O3-SiO2-Cs2O Glass

Methods for suppression and control of the axisymmetric vertical positional instability are described on the basis of conceptural design studies with the International Tokamak Reactor (INTOR). The shell effect is well known to be useful for suppression of the fast instability. Here shell structures are presented and their usefulness is assessed. Included in the assessments are required modellings of the plasma current for determination of mutual inductances between the plasma and the inductive components around it. Three kinds of models are described and their features are compared to the shell effect. Two kinds of simplified reactor structures are described and studied by comparing them with some control characteristics of the slow instability by a pair of control coils. Their structures are selected so as to result in different shell effects between them, and are consequently found to produce different capacities of power supply, too.     

Influence of display, response, and response set factors upon the storage of spatial information in complex displays.

Immediate recall for spatial information was studied as a function of stimulus load under 2 display formats, 2 response formats, and 2 response set conditions. 4 groups of 10 Ss each served under 15 replications of all response-format, stimulus-load conditions; groups were distinguished on the basis of display format and set. Each S viewed either a spatial or tabular display of 14-26 geometrical stimuli for 16 sec.; he was then required to report, on either a tabular or spatial response form, the location of relevant stimuli. Correct responses and misplacement errors increased more rapidly for the spatial format as more stimuli were presented. Recoding from 1 display to the other response format did not yield serious decrements. Contrary to expectation, response set enhanced all conditions to a nearly equivalent degree. Results are interpreted in terms of the "chunking" hypothesis. (16 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
