体积更小,却具有更强的能力;价格更低,却具有更好的性能;能效更高,性能却不能降低;更小、更便宜、更高效,却能够在最极端的条件下保持较高的耐用性。这些看似矛盾的要求在为航天器设计传感器等仪器设备的过程中却经常会遇到。例如,美国将于2011年发射升空的“好奇”号火星科学实验室计划搭载10 Smaller, yet more capable; Lower cost, better performance; Higher energy efficiency, lower performance; Smaller, cheaper, more efficient, yet able to maintain the most extreme conditions High durability. These seemingly contradictory requirements are often encountered in designing instruments and equipment such as sensors for spacecraft. For example, the United States will launch its “Curiosity” Mars Science Laboratory program to be launched in 2011 with 10
