摘　　要：描述了NSRL新建X射线衍射和散射光束线站的主要指标测试及其结果,包括X射线单色光斑的CCD成像(4mm×0.5mm)、波长标定和光子通量(0.4×10~9—2.1×10~9 photons·s^(-1)·(100mA)^(-1))的测量;已在该线站上应用同步辐射X射线成功地收集了5组700余幅磷脂酶A2和神经毒蛋白晶体的衍射数据,处理结果良好。The paper describes the measurement of main parameters of the X-ray diffraction and scattering beamline and station in NSRL, including X-ray imaging(4mm×0.5 mm) with CCD camera, X-ray wavelength calibration and the measurement of photon flux (0.4×109-2.1×109 photons ·s-1· (100mA)-1). A preliminary experiment of protein X-ray diffraction was carried out using a commercial imaging plate detector system, and the results were reported. Five sets of diffraction data of protein crystals were successfully collected on this bealine and station. Good structure results were obtained from the data
