In this paper, the Changchun city was taken as the study area. The data about 10 years on dustfall were collected, the change tendency of dustfall was disclosed. Dustfall samples from October 2005 to February 2006 and samples of pollution sources were collected also. The samples were measured and analyzed by particle size analyzer and ICP-AES. EF and CMB receptor model is used to make source apportiontment of the dustfall.

Methods Blood of ear lobe,finger tip and vein from 30 healthy volunteers were collected and their erythrocyte count,haemoglobin,haematocrit were examined and compared.

30例健康志愿者同时采集耳垂血、指尖血和静脉血，并分析其RBC、Hb、Hct及其相关数值的差异。

In order to achieve the setting up angle should be monitored and debugged, a new approach is brought up. With the CCD receiving the focusing spot of parabolic mirror, while rotating the parabolic mirror, collecting the focusing spot location information, the eccentric angle between the optical axis and the structural central axis could be found. System principle and design have been studied.The experimental results meet the need to test and monitor to the setting up angle of the discal parabolic mirror.

为了实现对抛物面反射镜的装配角度进行监控和调试，提出了一种通过CCD接收回转抛物面镜的聚焦光斑，同时旋转抛物面镜，采集光斑重心位置信息，从而计算出光轴与结构中心轴之间的偏心角的实现方案，并从方案原理和设计上对其进行研究和实验，实验结果证明该系统能应用于对盘状抛物面反射镜装配角度的测试和监控。
