目的：本研究的目的在於比较一般门诊常使用的电子血压计与手测水银血压计的准确性，以验证一般门诊中使用电子血压计的便利性是否兼顾准确性。

To improve the simulation accuracy and to make the increment of computation amount the smallest, the quantitative comparison was used to compare the effect of incident direction and difference accuracy on numerical dispersion with the changing of the ratio of horizontal and vertical gird. The results show that the rectangular grid is better than square mesh in suppressing dispersion and can avoid the low computational efficiency caused by high-order difference.

为提高模拟精度，同时又尽可能减少计算量，采用定量分析的方法，对比分析了横纵网格比变化时入射方向和差分精度等因素对数值频散的影响，分析结果表明，矩形网格较之正方形网格能更好地压制频散，同时可以避免高阶差分导致的低计算效率。

The accuracy of laser stripe center position is one of the main factors that influences the system accuracy.

激光条纹中心位置的准确提取是影响系统精度的关键因素之一。

A gear H62 which made in yellow brass with the same mode number m=0.34, 2mm thick and had a center hole, when the gap get C=0.5%t , and punched with compound punching die, and the dimension accuracy reached IT7, the part have a flat surface ,the verticality of tangent plane reached 89.5°, its roughness Ra magnitude are 12.5μm, height of burr are 0.10mm; and the punching part are punched with progressive die, the gap C=7%t , initial accuracy are IT11, and have an more rough surface, even can see the gap with eyes.

例如料厚t=1.5mm的H62黄铜冲裁件，选用C≤40%t单边Ⅰ类小间隙冲裁比选用C≤8%tⅢ类大间隙冲裁，冲件固定误差将加大40%～60%，精度至少降一级。此外，采有无搭边排样，冲件的误差要远大于有搭边排样冲件。无搭边排样冲件。无搭边排样冲件的精度低于IT12级，而多数有搭边排样的冲件精度在IT11～IT9级之间，料厚t＞4mm的冲件，尺寸精度会更低一些。

Results of the study indicate that the probability-based tagger outperforms the rule-based tagger, and that the probability-based tagger yields an accuracy comparable to that achieved when the tagger is used to tag English native speakers' texts. It is also found that the rule-based tagger does not perform stably, and that its accuracy is often affected by the quality of learner language.

研究发现，作为一种基于概率的自动词性赋码器，CLAWS7具有较为可靠的性能，其赋码准确率基本达到该工具为英语母语进行词性赋码时的水平，而作为一种基于规则的词性赋码器，Brill的赋码准确率不够稳定，受学习者语言质量特别是语言错误的影响较大。

结果：卵巢良、恶性肿瘤的CT诊断准确性均为89%，其中畸胎瘤达93%，卵巢区炎性包块的准确性为73%。

UDI dataset is used to verify the validation of the ABC. Experimental results show that the ABC has higher classification accuracy, with 5％ average improvement, than the naive Bayes one has. Especially, for the dataset containing strong associated attributes, 37％ improvement in accuracy is obtained.

应用UDI数据集对分类器进行了测试，分类结果表明，ABC算法的分类准确率明显高于朴素贝叶斯分类算法，平均提高5％，特别是对属性间有着较强依赖关系的数据集，其分类准确率提高了37％。
