Independent factors associated with radiation dose were patient weight (relative effect on DLP, 5%; 95% confidence interval , 4%-6%), absence of stable sinus rhythm (10%; 95% CI, 2%-19%), scan length (5%; 95% CI, 4%-6%), electrocardiographically controlled tube current modulation (–25%; 95% CI,–23% to –28%; applied in 73% of patients), 100-kV tube voltage (–46%; 95% CI,–42% to –51%; applied in 5% of patients), sequential scanning (–78%; 95% CI,–77% to –79%; applied in 6% of patients), experience in cardiac CT (–1%; 95% CI,–1% to 0%), number of CCTA s per month (0%; 95% CI, 0%-1%), and type of 64-slice CT system (for highest vs lowest dose system, 97%; 95% CI, 88%-106%).

与放射剂量有关的独立因子有：病人的体重（对DLP的相对影响，占5%）；稳定窦性节律的阙如（占10%的影响）；扫描的长度（扫描长度增加1厘米相当于DLP增加5%）；应用心电图控制的管电流调制（导致DLP降低25%；用于73%的患者身上）；100-kV 管电压（使DLP降低46%，应用于5%的患者）；序贯扫描（降低78%；应用于6%的病人）；对心脏CT的经验（降低1%）；每月CCTA的数量；64层CT系统的类型

Results Reconstructive coronary artery images of 1 patient with severe sinus arrhythmia were not displayed clearly.

结果 在56例行MSCT冠状动脉造影的患者中1例由于患者有严重的窦性心率不齐，重建图像质量欠佳，其余患者均成功显示冠状动脉各主支（左主支、回旋支、前降支右支冠状动脉）及部分3、4级分支，且可显示所有冠状动脉支架的形态、位置，其中18例患者的31个支架术后出现再狭窄，所有行MSCT冠状动脉造影检查的患者无一例出现并发症，所有CT诊断支架术后再狭窄的患者同时行选择性血管造影检查，其中14例患者的25个支架有支架术后再狭窄，CT诊断的准确率为80.65%。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
