Geographical distribution characteristics of urban visibility in Anhui province are analyzed using routine observational data at 17 urban stations during the period from 1980 to 2005. The visibility trends in 5 cities from 1955 to 2005 have been analyzed using the methods of Ridit analysis cumulative percentiles and frequency of "very good" visibility.

利用安徽省17个地级市气象站1980-2005年的能见度观测资料，分析了安徽省城市大气能见度的地理分布特征，并用Ridit、累积百分率和"非常好"能见度出现频率分析法分别对5个代表性城市1955-2005年的大气能见度进行了研究和分析。

Such classes are separated by 'natural breaks'in the frequency distribution or the analogous cumulative curve.

这样的级可由频率分布或类似的累积曲线中的自然断点划分开来。

Adverse events were similar in both groups, and the incidence of symptomatic heart failure was lower than expected among those in the trastuzumab group (less than 2%), which supports "the accumulating evidence that trastuzumab can be given concurrently with anthracyclines with a low frequency of symptomatic cardiac dysfunction, provided that low cumulative doses or less cardiotoxic anthracyclines are used, and careful cardiac monitoring is done," the authors said.

作者表示，两组的不良事件发生率相似，曲妥珠单抗组症状性心力衰竭发生率低于预期(低于2%)，这支持如下观点，&越来越多的证据表明，如果应用的累积剂量较低或心毒性蒽环类药物较少且实施严密心脏监测，那么曲妥珠单抗与蒽环类药物就能够联用且所致的症状性心功能不全发生率较低。&

Methods Multinuclear cell assay was used to investigate the frequency of hprt locus mutation both in normal healthy people and malignant tumor patients prior to and after radiotherapy with a cumulative dose of 54~72Gy.
