Through the principal components analysis of 27softwoods,we found that the directionality of cell arrangements was accordant with theevolution order of Ginkgoaceae,Pinaceae,Taxodiaceae,Cupressaceae,the more evolutivewood species,the stronger directionality of cell arrangements along radial,but thedirectionality of cell arrangement along the radial of Larix spp.which was abrupt changedspecies was comparatively weak.

通过对27种针叶材的主成分分析，发现木材细胞排列方向性强弱基本符合银杏、松科、杉科、柏科的进化顺序，越是进化的树种木材径向排列的方向性就越强。另外，落叶松属等早晚材急变的木材径向排列比较弱。

The field directionality, represented as a set of planewaves that are induced by the far-field sources, where only few of them are of the high amplitude, is com- pressible at the wavenumber-frequency space (spikes in the abovementioned terminology).

场方向性在波数－频率空间（在上面提到的术语中是尖峰）是可压缩的，这里场方向性表示为一组由远场源感生的平面波的场方向性，这些平面波中几乎没有高幅值的。

In such a way a series of vivid characters were produced during this period of timeIn the later half of 1940,movie literature scripts complied with the historical process of the Chinese modem literature,and echoed the turbulent tide of the times.Either emphasized on the consciousness of social criticism,or inclined to the consciousness of humanism,its ideological nature and the direction for creation was very explicit.But this "directional" expression and the demand were not conceptual,or stiffly inbreathed. It is the "concrete image",the "metaphor" of the text,revealed naturally in accordance with the development of the plot and the molding of characters.It can be said as "the wind rippled the surface of the water naturally" and presented excellent artistic technique and high standard.The film scripts writers of the society group undertook the Chinese movie tradition of moving with the history,on an unusual level achieved a new altitude of ideology,and obtained a new artistic achievements.

由于电影文学剧本独特的语言表达方式，其在人物塑造上具有不同于小说、戏剧的特点。1940年代后半期电影剧作者高度重视电影文学剧本中人物形象的塑造，运用电影化的思维方式来刻画人物，依托人物性格的发展来展开故事，使得这时期电影文学剧本在引人入胜的故事书写中，绘就出了一长串内涵丰富、形象生动、有血有肉的人物群。1940年代后半期电影文学剧本既顺应着中国现代文学的历史进程，又呼应着动荡巨变的时代大潮，无论是侧重社会批判意识的，还是倾向人文关怀意识的，其思想性或方向性是非常明确的，但这种&方向性&的表达和诉求既不是概念性的，也不是生硬的灌输，而是&具体形象&的，是&隐寓&文本之中，在故事情节发展和人物性格塑造之中自然而然地流露出来的，可以说是&风行水上，自然成纹&，呈现出高超的艺术技艺和水准。
