浅谈应用标准进行软件测试

国家标准GB T175 44规定了软件包的质量要求及针对这些要求如何对软件包进行测试的细则。质量要求从产品描述、用户文档、程序及数据三个方面进行了规定 ,测试细则依据这些规定制定。ISO IEC912 6 (1991)版由ISO IEC 912 6 (软件产品质量 )和ISO IEC14 5 98(软件产品评测 )两个标准代替 ,ISO IEC912 6表述了软件产品质量的内部质量、外部质量和使用中的质量 ,规定了内部质量、外部质量的六个质量特性 ,并细分为 2 1个子特性 ,使用中的质量规定了四个使用质量特性 ,使用质量是指六个软件产品质量特性的综合效果。进行软件测试时 ,可以依据GB T175 44中的规定组织测试过程再结合ISO IEC912 6中的质量特性及子特性的规定确定测试需求的内容和测试的重点 ,利用ISO IEC912 6质量的规定建立质量评级的标准。     

合成己二腈反应技术研究——(Ⅴ)己二腈工业反应过程模拟与反应器改造

对己二腈工业反应器提出了两釜串联带回流的模型,通过模拟计算得出模型的级间返混系数 f=6的结论。该模型能较好地预测工业反应器中物料组分浓度变化和气、液两相的流动特性;指出了现工业反应器的鼓泡中和段体积偏小是造成己二酸浓度偏高的关键;提出了可以通过增加串连一个鼓泡预反应段的改造方案,能有效地降低己二酸的浓度,从7%降至4%左右,从而能较好地减缓腐蚀和结焦。     

Enantioselective antiplatelet actions of nipecotamides

This investigation retrospectively examined changes in marital satisfaction following stroke. The relationship between such changes and other pertinent factors were also examined, including severity of aphasia, knowledge of aphasia, number of months after stroke, and length of the marriage. The subjects were 40 spouses of patients with aphasia grouped according to severity of the aphasia (mild, moderate, severe). Spouses completed two different measures of marital satisfaction--the Marital Satisfaction Scale (MSS) and the Marital Comparison Level Index (MCLI). These measures were completed in both a prestroke (retrospective reporting) and a poststroke format to allow for change to be assessed. In addition, a Knowledge of Aphasia questionnaire was completed by the normal spouses to evaluate their understanding of the disorder of aphasia. There was a significant difference between prestroke and poststroke scores on both the MSS and the MCLI, indicating a lower level of satisfaction following the stroke. The amount of change between prestroke and poststroke MSS and MCLI scores was not related to either number of months poststroke or number of years married. Although there was no relationship between changes in prestroke and poststroke scores on the MCLI and Knowledge of Aphasia scores, there was a significant correlation between changes in these scores on the MSS and Knowledge of Aphasia scores. Hence, the more knowledge spouses had regarding aphasia, the less the negative impact the stroke had on marital satisfaction, as measured by the MSS. Results are discussed in terms of the interdisciplinary treatment needs of aphasic patients and the implications for future investigations.

Kinetics of two-step anionic polymerization

This article deals with the kinetics of two-step anionic polymerization by way of a non-steady state method. Several molecular parameters can be evaluated using the formulae developed. A bimodal molecular weight distribution function for the resulting polymer is derived from the set of kinetic differential equations, which is in agreement with the experimental data reported.
