Methods: Eight hundred normal cases were chosen randomly for study. Ultrasound was carried out in vertical section at xiphoid process, cross section at middle abdomen, and coronary section at the waist to detect the presence of AHV. The function site, number of AHV, caliber, flow velocity and the angle between AHV and IVC were investigated.

The study results indicate that as emission power increases, the peak power density on the section of a certain distance will increase firstly, then it will descend and that the peak light intensity on the section will increase with the increasing of spot radius of basic mode Gaussian beam. As the propagation distance increases, the peak light intensity on the section will descend gradually, and the laser energy will spread. The light intensity distribution exhibits straw hat shape on a certain conditions, in other word to say, the central light intensity is less than acroteric light intensity.

结果表明，无风稳态热晕效应存在时，随发射功率的增大，一定传输距离截面上的峰值功率密度先增人后减小；截面上的峰值光强随基模高斯光束的腰斑半径的增大而增大；随着传输距离的增大，截面上峰值光强在逐渐减小，能量在逐渐向周围扩展；在一定条件下，截面上的光强分布会呈现中心光强小于周围光强的&草帽型&分布。

We used maize seedlings (Zea mays L.) and tobacco (Nicotiana plumbaginjfolia L.) as material. In the first section, we have investigated cold- shock-induced chilling, drought, heat and salt stress resistance in maize seedlings. In the second section, by modifying the Ca~ and CaM levels, we have tried to establish the involvement of calcium messenger system in the cold-shock-induced cross adaptation. In the third section, we have tried to establish a transgenic tobacco system expression CaMICaMIBP genes, so that the others can use it to investigate the process of physiology and biochemistry which endonuclear and cytosolic calmodulin have taken part in.
