TheJiyang depression located in paleomonsoon climate zone in the period of the sahejieformation sedimentation, the wet and hot climate made ancient lake become deeperwater, enhanced stratification, reduced primary productivity of plankton, decreasingsedimentary velocity of carbonate, increasing sedimentary velocity of clay, fortifiedreductibility on certain degree, and then would be available for development of blackshale, dark shale and oil shale; In the contrast, the cold and dry climate lead ancientlake to shallower water, subdued stratification, increaser primary productivity ofplankton, enhancive sedimentary velocity of aphanitic carbonate, decreasedsedimentary velocity of clay, and then would be available for development calciteshale, calcite laminar shale, calcite mudstone, shaly carbonate rock, even laminarcarbonate or dolomite rock.

济阳坳陷在古近系沙河街组沉积期属于古季风气候带，在湿热的气候条件下古湖水加深，分层性增强，浮游生物的古生产力降低，隐晶碳酸盐的沉淀速率变小，粘土沉积速率加快，还原性一定程度上有所加强，有利于黑页岩、油页岩和暗色泥岩的形成：而相对干冷气候下，古湖水变浅，分层性减弱，浮游生物的古生产力增高，隐晶碳酸盐的沉积速率变大，粘土的沉积速率减慢，有利于钙质页岩、钙质纹层页岩、钙质泥岩、泥灰岩甚至纹层状碳酸盐岩、灰岩的发育。

For a heterogeneous elastic solid consisting of two homogeneous layers, three homogeneous layers whose shear wave velocities increasing with depth, or three homogeneous layers whose interlayer has high velocity, if there are multi-mode dispersion curves, the phase velocity V〓 of the first mode will close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, and V〓 of the first mode will close up to the Rayleigh wave velocity of the top layer when f→∞.

The results show that the discharge and cooling stages of sparkjet were simulated by computational method. The instance energy input can produce the condition of high pressure and temperature in the actuator, which induce the forming of synthetic jet. With the increment of the input energy, the velocity of the synthetic jet could be increased to the supersonic state. Under the periodic energy input, the distribution of the sparkjet velocity on the nozzle is non-sinusoidal. And the discharge velocity of jet is much larger than the suction velocity of the flow from environment.
