摘要：
A system operable to monitoring bio/chemical activities includes a first measurement probe, a second measurement probe and a comparator. The first measurement probe is operable to interrogate one or more physical properties of a sample at a first location of the sample, and to output, in response, a first measurement signal. The second measurement probe is operable to interrogate one or more physical properties of the sample at a second location of the sample, and to output, in response, a second measurement signal. The comparator is coupled to receive the first and second measurement signals, the comparator configured to output a difference signal comprising the difference between the first and second measurement signals, the difference signal corresponding to the difference in one or more bio/chemical activities occurring at the first location of the sample relative to the second location of the sample.
摘要（中）：
可操作以监测生物/化学活性的系统包括第一测量探针，第二测量探针和比较器。 第一测量探针可操作以在样品的第一位置询问样品的一个或多个物理特性，并响应于输出第一测量信号。 第二测量探头可操作以在样品的第二位置询问样品的一个或多个物理特性，并响应于输出第二测量信号。 比较器被耦合以接收第一和第二测量信号，比较器被配置为输出包括第一和第二测量信号之间的差的差分信号，差分信号对应于在第一和第二测量信号发生的一个或多个生物/化学活动的差异 样品的第一个位置相对于样品的第二个位置。
