2. the structure of purple soil is meliorated by sabaigrass. when contrast to bare land treatment and natural wild grassland treatment we knew that sabaigrass treatment and grass tree solid plating treatment reduced soil bulk density, enhanced soil capillary porosity, non - capillary porosity and porosity ratio, decreased soil sand grain content, enhanced soil clay grain and silt grain content so as to reduced the dispersal degree of soil, improved the aggregate capacity of soil, increased the amount of soil aggregate structure, meliorated the water permeability of soil, accelerated the form of good soil structure
龍須草能改善紫色土的土壤結構龍須草純種植被和林草立體種植植被能不同程度地降低土壤容重，減少土壤砂粒含量，增加土壤的毛管孔隙度、非毛管孔隙度和孔隙比，以及增加粉粒含量，從而降低土壤分散度，提高土壤團聚性，增加土壤團粒結構數量，改善土壤的透水性，促進良好土壤結構的形成，最終提高土壤的蓄水保肥性能，增強土壤的抗蝕性和抗沖性。 -
4. influence of no on microvascular permeability : specimens from postnatal 1 day showed little immunoreactivity for enos. in contrast, blood vessel endothelium and leydig cells and spermatids in postnatal 3 weeks testes were strongly expressed enos. the number of positive blood vessel endothelium, leydig cells and spermatids in postnatal 3 months was conspicuously increased

3 ) the sandbody distribution, physical properties, pore structure and heterogeneities are affected by the microfacies. at the center part of underwater distributive river course, the petrophysics and physical properties are both better than that at the edge of the microface. 4 ) the chang 61 2 - 3 substrata and the substrata of chang 62 " member which show the better porosity, permeability, and better pore structure ; display lower permeability variation coefficient, dart - coefficient and contrast - coefficient and good connecting sandbody so the horizontal heterogeneities is weaker ; whereas manifest stronger inner - heterogeneities due to the numerous intermediates ; present stronger inter - heterogeneities caused by the greater frequency of sandbody
長6儲層中長6 _ 2 ~ （ 1 - 3 ）和長6 _ 2 ~ 1砂層中的各個小層的孔隙度、滲透率值、含油性較好；平面非均質性較弱，表現為級差、突進系數、變異系數較低且砂體的連片程度高，鉆遇率和連通系數較高；與此同時，層內非均質性較強，表現為垂向上夾層的數目較多，厚度較大；層間非均質性也較強表現為分層系數較高。
