In order to clearly recognize the geophysical response of carbonate reservoir,based on preliminary recognition of Ordovician carbonate reservoir under the basal surface in Tahe oilfield,some regular vug models and random arranged vug models were designed and built. The variable-grid finite difference method was used to simulate the seismic wave propagation in these models. Then,the seismic records of the models were analyzed and the effect to seismic reflections caused by vug is studied. The impact rule of regular vug scale and random arranged vug density on seismic attributes was obtained.

Methods: Forty mice were divided into four groups randomly:normal group,model group,ligation group and treatment group.The model was made by the method of partly ligating the recta outside the body.The level of endotoxin in blood plasma was measured by dynamic nephelometric method and the content of TNF-a in blood serum was detected by the method of radioimmunity.(2)After the mice were killed,their left lungs were taken out for bronchi-alveoli fluid, then the content of MDA in BALF was tested by TBA method.(3)The vitality of PAM in BALF was countied on the counting set of erythrocyte,and the blue-dyed cellswere counted, then the percentage of PMN was worked out.(4)The pathological features of the mice\'s lung tissue were observed with routine and ultramicro pathological mechanism.

The conditions to measure accurately and the principles to select parameters of the multi— probes EST method are proposed, and the theoretical research, computer imitation and the experiment on a machine tool prove that these principles and suggestion are necessary and effective. The influence of the initial value errors of the probes, the installation error of the probes system, and the remaining error caused by the radical error motion are analyzed quantitively on the measurement accuracy of the multi—probes EST method. The influence of the error caused by the probe's axes which is not in a plane and the perpendicularity error of the plane which the probe's axes is in to the stational axis are discussed on the measurement results.
