The method that measuring horzontal component of the earth magnetic field with digital quantometer is introdnces, the computational formule are given, systematic error are discussed, the advantages of the this method with tangent galvanometer measuring ho

摘要介绍了用数字冲击电流计测量地磁场水平分量的方法，给出了计算公式，对系统误差进行了讨论，简述了该方法与用正切电流计法测量地磁场水平分量的优点。

This paper advances a Fast BP algorithm. It accords to the system error to adjust learning speed. By procasting cotton heliothis armigera, we made a compare to these two kinds BP algorithm's convergence speed.

本文在对BP网络现行算法研究的基础上，提出根据系统误差自适应调节学习率的快速BP算法，并以棉花棉铃虫预测为例，对两种算法的收敛速度进行了比较。

The systematic biases monotonically decrease, and the systematic difference became obvious after a week.

模式系统误差单调递减，一周以后较为明显。

A comparison is made between total integrated and spectroradiometric methods of measuring illuminance.

一导言 用不同的方法测量同～个量，常常被用来检验测量方法中是否存在系统误差。

PID-NN algorithm based on the basic principles of PID is introduced for feedback controller that automatically adaptive to the variation of unit's parameters and assorts with feedforward compensation through on line learning.

反馈控制器按PID控制规律构造PID-NN网络，通过在线学习自适应机组参数的变化和与模糊前馈相协调，对系统误差进一步控制。

Equation 7 should be calibrated to understand distribution of the systematic errors.

方程7应该被校准来了解系统误差的分布。

The major reason maybe that the systemic errors in indirect hybridizing are more excessive than direct hybridizing.

结果表明，间接杂交的Log值的变化幅度要比直接杂交的大，主要原因是因为其实验系统误差要高于直接杂交

When UAV flying in horizontal, we described the formation of errors as changes from circle to ellipse in geometry, called ellipse hypothesis.

研究了飞机平飞时磁航向系统误差的形成过程，并把该过程描述为几何上从圆到椭圆的变化过程，即所谓椭圆假设。

It should be noted that if the optics spirit level is totally replaced by the electronic spirit level afterwards, the collimation error will be corrected automatically, since the electronic spirit level instrument has already built the formula of automatic correction.

因此，以后若电子水准仪完全取代光学水准仪，则此项系统误差改正可取消。

The paper develops R/S analysis which was referred by Hurst, and introduces R/S concept in broad sense, then analysis and discusses its computing condition, scale range and system error.

本文拓展了Hurst提出的原始的R／S方法，引入广义情况下的R／S概念，对它的计算条件、尺度范围以及系统误差进行分析。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
