允许误差

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。

The method for encoding a position interpolator includes generating key data and key value data to be encoded by extracting, from a first animation path constituted by the position interpolator, a minimum number of break points, which can bring about an error of no greater than a predetermined allowable error limit between the first animation path and a second animation to be generated by the extracted break points, encoding the key data generated in step, and encoding the key value data generated in step.

用于对位置内插器进行编码的方法包括：通过从由位置内插器构成的第一动画路径中提取最小数量的断点，生成将被编码的密钥数据和密钥值数据，这些断点可以在第一动画路径和将由所提取的断点生成的第二动画路径之间引起不大于预定的可允许误差极限的误差；对在步骤中生成的密钥数据进行编码；以及对在步骤中生成的密钥值数据进行编码。

The adaptive program is calculated by T-B stress recovery scheme and z-z error estimation, the error is estimated by energy norm of difference of recovery stress and meshless stress. If the local relative error exceeds the limit relative error, then new nodes will be generated at the high error area.

Result］ It could be concluded through analyzing the model that both the mass uncertainties of quinoline phosphomolybdate precipitates and tested samples were from the resolving power and precision of balance and its maximum tolerance in assay certificate; the uncertainty brought in by volumetric flask was from the permissible error of 250 ml volumetric flask, the operation of increasing the volume to scale of volumetric flask while diluting solution and the difference between experimental temperature and the temperature at the time when the volumetric flask was calibrated; the uncertainty brought in by pipette was from the permissible error of itself, the operation of increasing the volume to intake scale while taking solution and the difference between experimental temperature and the temperature at the time when the pipette was calibrated.

结果］磷钼酸喹啉沉淀和试样质量的不确定度均来自天平的分辨力、精确度、鉴定证书上天平的最大允差，容量瓶引入的不确定度来自250 ml容量瓶本身的允许误差、稀释溶液时将体积增加到容量瓶刻度的操作和试验温度与容量瓶校准时温度的差异，吸量管引入的不确定度来自于吸量管本身的允许误差、吸取溶液时将体积增加到吸取刻度时的操作和试验温度与吸量管校准时温度的差异。

Results :Satisfactory facial appearance was achieved in all the patients . Results showed that the repeatability was 100% when error tolerance was 3.5 mm. If tolerance was set at 2 mm, the repeatability was 97.8%.The biggest difference occurred in ramous area.

结果：5例患者均获得满意的术后形态，在差值分析分析中，设允许误差为2mm，真实术后与虚拟手术的吻合程度为97.8%；设允许误差为3.5mm，两者吻合程度为100%；最大差别产生的区域在双侧升支。

And by comparing the actual clock, find out the source of the error and determined the method of adjusting error, reduce errors as much as possibly, so this system can achieve a practical digital clock with error within the permissible range.
