同时，我们还研究了骆驼蓬的种子特性及群落分布特点，这些研究结果均有助于我们进一步了解植物种子的抗旱生理生化机制和群落分布规律，为荒漠治理及优势群落的发展与保护等提供理论依据。

Sequences from 19 randomly selected phage clones indicated that the distribution of nucleotides and amino acids paralleled the expected frequency. The combined index of hydropathy and isoelectric point of these 19 peptides were randomly distributed over wide ranges.

随机挑取了19个克隆，序列分析表明，核苷酸和氨基酸的分布与预期的基本一致。19个多肽的疏水性和等电点的综合指标分布广泛。

And after analyzing the heterogeneity of sand body, point the minor channels, especially, have important influence on the intraformational oil-flooding direction, forming and distribution of remaining oil because of their function as barrier, breaking fluid and poor permeability in fluvial sand body.

通过非均质性研究，进一步揭示了单一河道砂体内部非均质性，特别是次分流河道砂体的分布，在河道砂体内起到遮挡、阻流、特低渗透等作用，对层内水驱油方向、剩余油形成与分布具有重要影响。

From the isohyetal maps, we can display the spatial distribution of rainfall caused by typhoons in Nan Shih Creek watershed.

由等雨量线图显示，南势溪集水区台风降雨之分布分别由东向西以及南向北之方向递减；台风降雨中心多发生於福山雨量站所在之区域，降雨量则由福山雨量站向东朝下盆雨量站方向递减；另外，位於本区北端之大桶山雨量所处之区域，则是另一处发生明显降雨空间变化的地区，故台风降雨在南势溪集水区内的分布具有空间变异之特性。
