severe error

This Paper analyses the disadvantages of the current method for testing EDM additive constant and arrives at a conclusion that periodic error contaminating EDM additive constant is very severe. Three optimum methods are then given by this Paper.

本文首先分析了红外测距仪加常数现行检测方法的弊端，得出结论是周期误差严重污染加常数，进而提出净化加常数的三种方法；

Using intubatton in trachea and non-trachea airway ( NTA) in ventilate, disturbance oesophagus and bronchia of acute and severe anaesthesia and anabiosis patients, but there were the danger of stomach adverse current and error absorb.

采用气管内插管及非气管性通气道（non-trachea airway，NTA），用于麻醉、复苏等急危重病的通气及阻隔食管、气管，仍存胃内容物返流、误吸的危险。

Error of laser beam pointing has severe influences on the received power and bit error rate in the link of inter-satellite optical communication.

卫星间光通信链路中对准误差对接收功率和误码率都有严重的影响。

In the low-frequency elastic wave through-the-earth communication system, severe Inter-Symbol Interference ( ISI) is generated and the bit error rate ( BER) is increased after transmission because of the multipath transmission caused by the characteristics of the layered earth.

在低频弹性波透地通信系统中，由于分层大地信道的多径传输特性，弹性波信号经过信道传输以后，产生了严重的码间干扰，增加了通信的误码率。

The existing algorithms include equivalent left and right curve angle by definition, normal section line method and tangent projection etc. But all their precisions are limit to one-order truncation error, and make severe accumulate error on discrete models.

有关的算法有根据定义的左右曲面角相等，法截面法和切向投影等。这些方法的精度都局限在一阶截断误差，在离散的网格上有严重的累积误差。
