Shannon showed that noise sets a limit on the rate at which information can pass along communication channels while remaining error-free.
香农指出，噪声限制了信息在保持无差错的情况下沿通信信道传递的速度。
It was possible to increase the accuracy by performing the strain measurements via sub-steps. This had a remaining error of 0.41% for 7.22% vertical strain.
但是有可能通过亚步应变测量来提高系统的精确度，这样对于7.22%的垂直应变具有0.41%的剩余误差。
Then, the troposphere pseudo-range remaining error (TDRE) of differential GPS (DGPS) is defined, its mathematical model is constructed, and the computer simulation of TDRE of DGPS is carried out.
定义了差分GPS（DGPS）的对流层伪距残差的概念，并建立了数学模型。 用计算机对DGPS的对流层伪距残差进行仿真。
