查询词典 observational error

The 1995/6 Saturn Ring Plane Crossing observations found that Prometheus was lagging by 20 degrees from where it should have been based on Voyager 1981 data. This is much more than can be explained by observational error.

根据1995年6月的土星光环平面交叉线观察发现，土卫十六比从旅行者号1981年数据算出的所在位置落后了20度，这是不足以用观察误差所能解释的。

Based on practically stable principle, this paper extends the concept of sliding mode to sliding zone attraction and presents a new velocity observer for robotic tracking control It can guarantee observational error is irrelative to motion trajectory. By means of it, a robust controller is further derived.

本文基于实际稳定性原理，推广了滑动模控制，提出了滑动域吸引性设计思想，并以此设计了机械手速度观测器，以及基于观测器的机械手输出反馈控制系统，与以往观测方案不同的是，这一观测器可以保证其观测误差与机械手运动轨迹无关。

Meanwhile, new observation operators are designed for routine observational data, and background error covariance is also calculated. Currently, the m3DVAR system is able to assimilate all the conventional observations data, such as sounding, surface and ship data, etc.

重新构造各种观测算子，并考虑了质量场和风场之间的平衡约束关系、背景误差协方差结构，实现对探空、地面资料、船舶报等常规观测的同化。

Using a fitting method which can reasonably assign weight to the observational data including two quantities with different dimensions, we obtain a V-band MRL based on the dynamical masses and luminosities of 203 main sequence stars. Compared with the previous work, the improved MRL is statistically significant, and the relative error of mass estimation reaches about 5%.

利用一个能合理分配两个不同量纲观测量权重的拟合方法，根据203颗恒星的动力学质量和光度数据给出了主序星的V波段经验质光关系，该结果对此前结果的改进不仅具有统计显著性，而且其对恒星质量估计的相对误差已达到约5%。

Making use of structural characteristics of the Lower Latitude Meridian Circle and the error theory of this instrument, we have developed a method used to measure directly instantaneous atmospheric refraction, and moreover built a local observational astronomical refraction model toward the east, south, west and north of Yunnan observatory that is classified according to the star's spectral type.

阐述了云南天文台探讨出的利用低纬子午环的观测原理，在不同方向和不同天顶距直接测定瞬时大气折射值的一套方法，并给出了用实测数据在东、南、西、北4个方向建立的按恒星光谱型分类的大气折射实测模型。

The result is evaluated using mean absolute error, maximum absolute error and minimum absolute error.

所选用的精度指标包括：绝对值平均误差、绝对值最大误差以及绝对值最小误差三种。

The dependent variables were absolute error, variable error, and error detection capability.

依变项为动作准确性、稳定度和错误侦察能力。

Through compared with the difference of the sampling inspection's OC curves between existent and nonexistent inspection error by utilizing grouping method, we get the conclusion that all the traditional methods are designed on the premise that there is none inspection error exist, so it would terribly depress the probability of acceptance and couldn't veritably reflect the quality of the lot for inspection, if the inspection error is exist when sampling inspecting.

同时通过对集团检验错误存在与否的抽样检验特征曲线的比较，指出：以往的集团抽样检验方案设计，都是在假设无检验误差前提下设计的，在抽样检验中，若存在检验错误，会严重影响抽样检验的接收概率，使抽样检验结果不能客观地反映检验批的质量。

And the temperature error could be divided into accidental error and systematic error.

其温度误差分为随机误差和系统误差两部分。

Sampling error or allowable error is conventionally accepted between 1% and 10%; however, it is suggested that sampling error should be carefully assessed in light of the nature of the derivation of the population proportion and other aspects of the initial data.

抽样误差或允许误差是接受常规的1 ％和10 ％，但是，有人建议，抽样误差应当认真评估根据的性质推导的人口比例和其他方面的初步数据。

But this is impossible, as long as it is engaging in a market economy, there are risks in any operation.

但是，这是不可能的，只要是搞市场经济，是有风险的任何行动。

We're on the same wavelength.

我们是同道中人。
