* The data from these are collected and transmitted to a central processor using a common digital bus. 使用普通的数据总线将收集并传送这些数据到中央处理器。 The many inputs then need to be combined in some way to decide such conditions as emergency states, when to change the oil, and engine efficiency. This combination is a “mapping of many to a few”. 当改变油量、发动机的效率时，在某种程度上这些输入需要被组合以决定这种情况是紧急状态。这个组合就是是一个“多对少映射。 Mapping in General * These are not always simple mappings, for there is no adequate algorithm available to give a mathematical description for such things as degradation of oil condition. 这并非是简单的映射，因为没有合适的算法为如原油降解这样的情况可以给一个数学描述。 Mapping in General However, human intuition can be used quite effectively to obtain answers—the human mind is very capable of carrying out such mapping functions. 然而，人类的直觉可以相当有效地被使用以获得答案—人类智力能够完成映射函数。 * This form of natural processing makes use of what are technically called “heuristics” –but more commonly known as “rules of thumb.” 自然处理形式利用了技术上称为 “启发法”技术—更常被称为“经验法则”。 Mapping in General Consider the question, “How could we decide, using an automated measurement system, When loaves being made in a bakery are satisfactory to sell?” 考虑这个问题,“在一家面包店里，什么时候做的饼是卖得满意的?我们如何使用一个自动测量系统决定”。 * As the way to decide this almost all people asked would suggest that the weight, size, crustiness, appearance and softness inside would be the parameters that must all be satisfactory (that is, lie within a small range of values for each) to be declared suitable. lie within在…范围之内，位于…内；受…的影响 declared 呈报 公开承认的 公然的；公开宣布的 按照这种方式去决定将几乎所有被问的人认为的重量、尺寸、硬壳、外形和内部柔软性作为参数，这些必须使公开宣布的适宜参数是令人满意的 (也就是说，在小范围内的每个值)。 Mapping in General * Unit 13 测控技术与仪器专业英语 Signal Process Chapter 3 Introduction to Measurement/test Technology and Equipment * Words and Expressions algorithmic method 计算方法 artificial intelligence(AI) 人工智能 mathematical equation 数学方程式 decision theory 决策论 formalism 形式主义;形式体系 computing effort 计算代价; 计算量 calibrate 测定口径；
