Applying the results in this research subject , the author devised the schema for environmental adaptability design and reliability design of many important projects ( for example : system product of western system and product of anti - adverse circumstances for atc , etc ) of the factory no . 783 , and the environmental adaptability test verification and reliability evaluation test , trial and use in external field have been passed 笔者运用本研究课题的成果,为783厂多个重点项目(如西方体制系统产品及抗恶劣环境航管产品等)的环境适应性设计和可靠性设计制定了方案,并通过了试验室的环境适应性试验验证和可靠性鉴定试验,外场的试用和使用。
This article explored the operation and design of fresh milk favoritism sensual evaluation test so as to discuss some sensual evaluation styles of commonly seen , results and analyzed the result of fresh milk sensual evaluation by fuzzy mathematics , and also discussed the influence of personal factor for the result of the test 摘要本文以鲜奶为例对偏爱型感官评价的实验设计和评价分析进行了探讨,介绍了常见的感官评价类型,对鲜奶感官评价结果运用模糊评价法进行了分析,并讨论了试验过程中评价人员因素对评价结果的影响。
This instructional design draws its model and principle from a variety of disciplines : learning theory , systems theory , communications theory , and instructional theory . its major content involves the following component : front - end analysis , clarifying instructional objective , writing evaluation test questions , designing instructional strategy , writing instructional solution , formative evaluation of systematic instructional design , and revising instruction 这种教学设计是以学习理论、系统论、传播理论和教学理论为基础,运用系统方法进行教学设计的理论和模式架构;系统教学设计的基本内容包括前期分析,教学目标的阐明和评价试题的编制,教学策略的设计,教学设计方案的编制,系统教学设计的形成性评价,修改教学;最后,构建了以上述内容为要素的系统教学设计模式。
With the increase of communication systematic complexity , traditional analysis design method can not fit in with the needs of development . if the experiment is carried on the true system directly each time , which not only costs expensivly , takes a lot of time , sometimes even it is difficult to find the very crux of the question . therefore , the effective method is to adopt the emulation technology of the computer . so that the computer ' s ability of high - speed computation can be used , and the analysis , design , optimization of performance and evaluation testing of optic fiber communication equipment and system can be finished 随着通信系统复杂性的增加,传统的分析设计方法已经不能适应发展的需要。如果每次都直接用真实系统进行实验,不仅耗资昂贵,费工费时,有时甚至难于找到问题症结所在。因此,解决上述问题的有效方法是采用计算机仿真技术,利用计算机的高速运算处理能力,完成对光纤通信设备与系统的分析、设计以及性能优化与评估测试。
