It's found that the (001) facet is the growth facet when the NBW crystal is grown by the Bridgman method through spontaneously crystallization. This phenomenon is in accordance with the growth characteristic of the typical scheelite crystals, and can be well explained by the Bravais law and the theory of anion coordination polyhedron.

指出坩埚下降法自发成核NBW晶体生长生长面为(001)面,这与白钨矿结构晶体(001)面生长快的特点是完全符合的,Bravais法则和负离子配位多面体生长基元理论都能够很好地解释这一现象。

F. pumila had the strongest capacity to adhere to walls, and it formed a quite good covering landscape by means of a large quantity of adventitious roots. Furthermore, it was tolerant to shade, and the effects of shading on its growth and landscape covering were very small. P. heterophylla had the rapidest growth and covering speed, and it adhered to walls by adhesive discs, but was defoliated in winter or after a long period of shading. The other three vines climbed walls using adventitious roots, and their adhering capacities were all relatively poor. However, E. fortunei still formed a relatively good covering due to its rapid growth and emerald leaf colour. After shading for four months, leaves of F, pumila, C. grandiflora, and P. serpens became thin, and accordingly their leaf weight per unit area significantly decreased. Shading also reduced chlorophyll contents of C. grandiflora and E. fortunei but enhanced those of F. pumila and P. serpens, It did not influence leaf thickness, leaf weight or chlorophyll content of P. heterophylla. Whether shaded or not, the relationship between Pn and PAR for each species could be expressed as y=alnx+b, and furthermore there was a significant (P.01) correlation between them. Pn and LCP values for all five lianas also significant (P.01) correlated. Shading reduced LCP values of P. heterophylla, C. grandiflora and E. fortunei but increased LSP of F. pumila.

结果表明,1薛荔对墙体附着力最强,它依靠大量的不定根吸固在墙体上,形成很好的覆盖效果,而且薜荔耐荫,遮光对其生长与覆盖的影响很小;爬墙虎的生长与覆盖速度最快,它主要依靠吸盘吸固墙壁,但在冬季或长时间遮光后出现明显落叶现象,影响其覆盖景观;其他3种都依靠不定根沿墙面攀援,附着力相对较差,但扶芳藤由于生长较快,叶色终年保持翠绿,也能形成相对较好的覆盖效果;2遮光4个月后,薛荔、凌霄和蔓九节的叶片变薄,相应地这3种植物单位面积的叶片重量都显著减轻;遮光还使凌霄和扶芳藤的叶绿素含量减少,使薛荔和蔓九节的增加,但对爬墙虎的叶片厚度、叶重和叶绿素含量都不产生明显影响;3无论遮光与否,5种植物的Pn与PAR之间的关系都可用y=alnx+b表示,并且都达极显著相关,Pn与光补偿点之间亦呈极显著相关;遮光还使爬墙虎、凌霄和扶芳藤的LCP下降,并使薛荔的光饱和点升高。

Applying the Whitney-Riley model to the soil-root complex, calculating formulas, which were related to modulus of elasticity E in direction of plant roots growth, modulus of elasticity E to be vertical to direction of plant roots growth and shearing modulus G in plane of plant roots growth, were established.

That a root system growth is more complete when fractal dimension value is higher, and when a growth of root system is simple and slow, then its fractal dimension value is smaller, and the same fractal dimension or the dimension is near, the form construction of root system becomes to similar.

当碎形维度值愈高,根系生长愈复杂,当碎形维度值愈低其根系的生长型态较简单且生长较慢,而且当两者之碎形维度很接近时其生长的型态也非常相似。

C. gloeosporioides mycelium grew well on media with fructose and glucose as carbon source while sorbose and starch promoted sporulation.
