相似条件

For general engineering problems, the analytical transformation rules are sufficiently accurate to design the similar cascade profile, but further improvement of the precision is limited by the one-dimensional assumption of the transformation, therefore an inverse blade design method—influence matrix method, based upon the surface vorticity model, is developed to improve the precision effectively.

进一步讨论了在具有相同表面压力系数分布的情形下，进口马赫数对附面层发展的影响，发现在一定条件下，只要表面压力系数的分布相似，则叶面附面层发展情况及无量纲气动力参数也将存在相同精度的相似，这一结论使我们在进行相似流场模拟的模型设计中，得以只进行无粘流场之间的相似变换，从而大大减少相似模型设计的工作量和复杂性。

We have successfully synthesized hydrocarbonbearing inclusions in carbonate at the temperature and pressure of 150 ℃ and 40 MPa, which are near the condition of natural reservoir underground 4 kmAll synthetic hydrocarbonbearing inclusions have been analyzed by microscope and microfluorescence and fourier transform infrared spectroscopyThe results show that the synthesized hydrocarbonbearing inclusions are very similar to those in real reservoirsOur experiments give us four important insights, including:(1) immiscibility of oil and water is the main reason for hydrocarbonbearing inclusions and aqueous inclusions distributed in different fractures;(2) rapid accumulation of oil and gas can be recorded by fluid inclusions;(3) the study of synthetic hydrocarbonbearing inclusions at the temperature and pressure of real reservoir will offer references and standards for the analysis of fluid inclusions in reservoirs;(4) experiment of synthetic hydrocarbonbearing inclusions is a good method for understanding the mechanism of oilwaterrocks interreaction in reservoirs.

文中报道在实际储层温压条件下(150 ℃，40 MPa，大约4 km深度)成功合成了碳酸盐岩烃类包裹体。通过对合成烃类包裹体的显微观察、荧光分析和傅里叶变换红外光谱分析，证实合成了烃类包裹体，且与真实储层中的包裹体具有相似特征，探讨了油水不混溶条件下的流体包裹体捕获机制。实验研究给出4点重要启示：(1)油水不混溶是造成烃类包裹体和水溶液包裹体分带的主要原因；(2)油气快速成藏过程可以被流体包裹体记录；(3)实际储层温压条件下，合成烃类包裹体实验研究有望为储层包裹体分析提供依据和标准；(4)人工合成烃类包裹体为研究含油气条件下储层水岩作用机理提供了一种有效手段。

按照优化的RAPD条件进行实验，重现性良好。2种裸腹在盐胁迫条件下的种群遗传多样性分析表明，同种裸腹不同生存盐度之间的种群遗传相似度较高，分别为0.9134和0.9038；而多刺裸腹和蒙古裸腹两个种间的遗传相似度相对较低，约为0.5～0.6。

Significant effects of warming onbiomass allocation were only found for the A. faxoniana seedlings grown under lowlight conditions, with significantly increased in leaf mass ratio and decreasedin R/S in responses to warming manipulation. The carbon allocation responses of B.albo-sinensis seedling to warming under full light conditions were similar with theresponse of A. faxoniana seedlings grown under low light conditions. Warmingsignificantly decreased root mass ratio, and increased leaf mass ratioand shoot/root biomass ratio for the B. albo-sinensis seedlings grown under fulllight conditions.

无论在全光或林下低光环境下，增温都促使云杉幼苗将更多的生物量分配到植物地下部分，从而导致幼苗在增温条件下有更高的R／S比；增温仅在林下低光条件下促使冷杉幼苗将更多的生物量投入到植物叶部，从而使幼苗R／S比显著地降低：增温在全光条件下对红桦幼苗生物量分配的影响趋势与冷杉幼苗在低光条件下相似，即增温在全光条件下促使红桦幼苗分配更多的生物量到植物同化部分一叶部。
