人为误差

Now the controllability theory in linear systems over the field R of real numbers has been heavily studied. This theory is efficacious for analyzing the characters which are determined by the value of physical parameters and system structure, nevertheless a practical system has a definite structure and has approximate, even unknown parameter sometimes because of a limit to experiment conditions, or a limit to making technology, the errors of observation. It is inconvenience for a linear system over the field R of real numbers to analyze the structure characters of a physical system, such as structural controllability.

目前，实数域上的系统的完全能控性理论研究已经很成熟了，它用于分析系统结构和物理参量的值共同决定的那些性能是有效的，然而，在工程中，由于实验条件或者制造工艺上的限制和观测上的误差，以及人为地对数据的近似处理，一个实际系统往往其结构是确定的，而参数只是近似的甚至未知的，实数域上的系统不便于分析物理系统的结构性质，如结构能控性。

This method requires manual operation, and it also has minor errors caused by human vision.

该方法需要人工操作，并且存在人为目视产生的误差。

The new method can avoid fluorescence quench caused by high concentration of measured fluid and personal error. It is especially suitable for fluorescence analysis of condensate oils, light oils and some mud additives with lower wavelength than 400 nm.

该评价方法克服了荧光自熄和浓度消光现象，避免了人为产生的误差，测试结果有效性强，特别是对于凝析油、轻质油及荧光发射波长小于400nm的钻井液添加剂的荧光评价更为有效。

As a result of error distribution\\\'s non-uniqueness, draws out to the standard deviation understanding again, by about standard deviation reflected that the erroneous zero rank value two side the variation targets, the application unimodal distribution fits the error distribution, the goal is: By approaches the rationality which under the enhancement goodness of fit\\\'s premise determines to the error.

从文章的上下文感觉此标准值似乎是人为规定的，并不受实测数据本身分布的影响，不具有客观性。个人认为：研究在实际中实测数据相对于均值的分布更有意义。按照作者的观点，误差的分布都是单峰的，除了正态分布这种对称分布外，作者认为还有不对称的偏峰分布。因此研究这种偏峰分布模型可能更有意义。

Just like what Professor Coker said: putting mash onto one's head leading his headache disappear means nothing to scientist.

随机就是为了减少人为的误差，对照就是考虑到实验条件之外的其他影响因素。

Based on the analyses of the anthropic factors resulting in test error of Engler viscometer , a method for improving the testing accuracy of Engler viscometer is studied in the article.

在分析了恩氏粘度计产生较大测试误差的人为因素的基础上，探求了提高恩氏粘度计测试准确度的措施。

This paper gives a brief introduction to the fundamental theory and working process of uncabled depth measuring device. When using this system the depth time function is recorded above ground, coupling time function is done under well and the depth coupling function is got from functional exchange.

简要介绍了无缆深度检测装置的基本原理和工作过程，该系统由地面记录深度—时间函数，井下记录接箍—时间函数，经过函数变换得到深度—接箍函数，然后利用前磁、油管深度资料对接箍深度进行校正，从而可以得到井下仪器准确的位置，解决了基础试井深度监测中由于人为因素、机械因素等造成的深度记录误差。

However, as a result of the calculation and regulation error of cutting machine, the spiral bevel gears that are produced by cutting once are difficult in attaining good contact and transmission quality. Therefore, it is necessary to simulate the transmission of real gears and then to find optimal cutter and cutting machine parameters.

但是，由于人为计算和生产、调整过程的误差，一次试切加工出的弧齿锥齿轮一般难以达到最佳的接触传动质量，因此根据现有切削参数对弧齿锥齿轮进行接触传动的仿真，从而找出较好的切齿刀盘和机床调整参数是非常必要的。

The major issues with GPS, namely 2 feet vertical guidance accuracy near the runway threshold and the integrity of the system has not been able to match historical ICAO standards and practices.

gps主要的问题是，跑到末端的垂直导航精确度是2英尺，系统的完整性（就是没有人为因素可以增加导航误差。。
