正确答案及解析
正确答案
解析
题意想要表达意思是只限于理论方面研究,正确答案为D。Theoretical:理论。附(参考翻译):计算机将会变得越来越高级而且更易于使用。识别速度提升将使计算机操作更加容易。虚拟现实是使用人感觉不计算机迚行交互一种技术,它也会使得人机界面更好。另外,各种新奇计算模型正在不断发展,如生物计算使用人器官、分子计算使用具有特定属性分子、DNA计算采用遗传基本单元来存储数据和执行操作。到目前为止,这些都还属于未来计算平台,能力非常有限,并且只限于理论方面研究。科学家们之所以研究这些计算模型,原因在于嵌入硅片中微型芯片体积局限性,以及即使是非常小晶体管所产生热量方面局限性。
