The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

方法回顾性分析200例行适应性前瞻性心电门控双源CT冠状动脉血管成像的患者(排除扫描过程中，屏气配合差，出现心律不齐的患者及行支架置入或搭桥术后复查的患者)，包括屏气时平均HR≤75 bpm患者122例，HR≥91 bpm患者78例；其中30例同期行选择性冠状动脉血管造影，按屏气时HR将其分为2组，A组17例：HR≤75 bpm，B组13例：HR≥91 bpm，分别与金标准SCAG对照，计算2组患者的阳性诊断准确率，应用SPSS 13.0统计学软件，利用Kappa检验比较每组患者的2种诊断方法诊断结果的一致性，利用两样本率x~2检验，比较2个心率组间的诊断准确率有无明显统计学差异，并计算此30例患者的平均有效辐射剂量。

结果：MSCT对引起梗阻的肿瘤定位、定性准确率分别为100%、97%，对其TNM分期的准确率为69.7%、78.8%、100%，对其浆膜外侵犯的敏感性和特异性分别为77.8%、33.3%，对淋巴结转移的敏感性和特异性分别为80.9%、75%。

The results and conclusions were as fellow: First, the four golfers perform inefficiency in last three year; decreasing return to scale; slack variable analysis as the training goals; sensitive analysis reveal that Candie Kung should advance items of driving accuracy, driving distance, sand saves, putting average and money list; Amy Hung and Teresa Lu were greens in regulation percentage; and driving for Yu Ping Lin.

结果与结论：首先，我国四位选手近三年来参赛总效率皆为相对无效率；规模报酬呈递减状态；差额变数结果做为最佳训练目标；敏感度分析发现龚怡萍需加强重点项目为开球距离、开球准确率、沙坑救球率、平均推杆数与奖金数表现，洪沁慧与卢晓晴为上果岭成功率，林玉萍为开球准确率。

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。

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％。

To simulation of weather patterns, the capability of stimulation to 850hPa is not as good as the one to 500hPa, which may be caused by underlying surface. In addition, the capability of stimulation to 48h is also not as good as the one to 36h. By analysis of result of stimulation to heavy rainfall happened on 8 July, 2003, we have found that rain belt location and its heavy rain core amounts in sensitivity run are preferably displayed by MM5V3. Analyses indicate this event was in close relationship with the southwest low vortex moving to east from the Tibetan Plateau and low-level jet in front of vortex and shear line.

模拟结果总体的TS评分、大雨以上准确率及暴雨以上准确率较MAPS模式都普遍更高；在对天气形势场的模拟能力方面，模式对850hPa上天气形势场的模拟效果不如500hPa上的模拟效果好，其可能原因是受下垫面的影响所致，并且总的看来，36小时的模拟效果优于48小时的模拟效果。

The results showed that different colour of male parent has no significant difference effect on feather autosexing accuracy rate of filial generation, while different colour of female parent has significant difference effect.
