认为反应器上升段表观气速对液相水平速度和垂直速度均有影响，其中对液相垂直速度的影响更大：表观气速增大，液相最大垂直速度一般增大，但这一变化规律并不是单调的；PIV对折流区的观测反映了该区域流场在气相通入后的最初25 s内的变化历程，流场发展的快慢与进气口的气速有关，气速越大，流场发展得越快。

The results showed that (1) The grain size of nanometer YiO_2 was40～80nm.The wavelength corresponding to the maximum absorbency values were observedin the 200～320nm range.The crystal structure of carbon doped TiO_2 photocatalyst is primarilyanatase(22.43% rutile), and the content of carbon is about 4.6%.(2) The relative humidityvaring from 8% to 80%, the photocatalytic degradation degree of benzene increased withincreasing relative humidity; and to toluene, degradation rate was hanced by relative humidityup to 60%, and more or less inhibited above 60%.(3) Scheme and results of orthogonal testswere used by evaluating the photocatalytic performance of the gas phase methanol, acetoneand 1-heptane.The results revealed that their degradation degree reached 84.5%, 93.39% and93.45%, respectively.(4) The 254nm UV lamp showed higher photocatalytic degradation rate.For methanol, acetone and 1-heptane, it was found that photocatalytic degradation reactionoccurs with the light strength of daylight lamp.(5) Under the the same conditions, 15%degradation degree has been obtained for benzene, whilst about 10% degradation degree wasattained by Degussa P25; During the initial phases, the toluene revealed higher photocatalyticactivity, comparing with Degussa P25, the degradation degree of methanol, acetone and1-heptane were slightly lower.

In combination with seismic reflection features and probable gas resource discussion, it is concluded that there probably exist two kinds of reservoir models in the X Block. In the areas where faults or collapse structures develop, the gas resource is probably composed of thermogenic gas, gas hydrate is characterized by multilayer distribution, while in the inactive areas the gas resource is probably composed of biogenic gas, and gas hydrate is characterized by monolayer, which mainly distributes in a narrow zone on the surface of BSR (bottom-simulating seismic reflector).
