软件设计到1980年代都很难让经验丰富的工程师接受,因为化学工业过程的几何分析中,往往需要丰富的现场经验,而不是仅仅依靠公式计算可以得到的。年轻的缺乏经验的工程师的设计常常被否决,因为和实际的运行结果有比较大的差异。具体表现在热交换器壳的堵塞和管束间的不规则振动。为了避免超规定的振动,在设计时往往比较采取保守的 Software design by the 1980s was difficult for experienced engineers to accept because of the geometric analysis of the chemical industry process, often require rich field experience, rather than relying solely on formula calculations can be obtained. The design of young, inexperienced engineers is often overruled because of the large differences from actual operating results. Specifically manifested in the heat exchanger shell blockage and irregular vibration between the tube bundle. In order to avoid excessive regulation of vibration, the design is often more conservative
