Phylogenetic analysis suggests that the batrachian divergence occurred in the Middle Permian, rather than the late Carboniferous as recently estimated using molecular clocks18, 22, but the divergence with caecilians corresponds to the deep split between temnospondyls and lepospondyls, which is congruent with the molecular estimates.

III Investigations of ferromagnetic alloy films by XMCD1. By using XMCD and SQUID magnetometry, the spin and orbital moments of Fe and Co in the Co_(0.9)Fe_(0.1)(50nm) are studied. Compared with single-element film, the spin moment of Co remains constant while that of Fe reduced from 1.98 to 1.63μB. The contributions of different elements in the film is, m_ : m_ - 10.5 : 89.5. The average magnetic moment (1.90μB) determined by XMCD is in agreement with that (1.82μB) obtained from SQUID measurements. Utilizing XMCD spectra in-plane element-dependent magnetic anisotropy in Co_(0.9)Fe_(0.1) films has been investigated. Apart from known field-induced easy axis during film growth, a soft axis perpendicular to it was observed, and hard axes are 66° away from the easy axis.

利用XMCD谱研究了50nm Co_(0.9)Fe_(0.1)薄膜,结果发现:样品中Fe、Co元素对磁化强度的贡献比为10.5∶89.5;由XMCD获得的合金平均原子磁矩1.90μ_B与用SQUID磁强计得到的合金平均原子磁矩1.82μ_B基本相符;对Co_(0.9)Fe_(0.1)薄膜面内元素分辨的磁各向异性的研究发现,除了在生长的磁诱导方向存在易磁化轴外,与该轴垂直的方向还存在一个类似易轴的软磁化轴;面内的两个难磁化轴与易磁化轴取向大约成66°夹角,构成面内双轴磁各向异性,并根据XMCD结果对面内双轴形成的原因进行了分(来源:Ad2BC82论文网www.abclunwen.com)析。2。

Three primer pairs located in psbA~trnK, psbB~psbH and trnR-ACG~trnN-GUU regions were applied in phylogenetic analysis according to Maximum parsimony and Neighbor-joining methods. The consistent results between the phylogenetic analysis and taxonomy indicated the application potential of the three primer pairs in phylogenetic analysis and species identification. However, due to no sequence variation observed in amplified regions between two vegetable soybean varieties (KS5 and KS8), two cowpea subspecies (Vigna unguiculata ssp. cylindrica and Vigna unguiculata ssp. sesquipedalis), and among three rice varieties (TNG67, TK9, and TCS10), the three primer pairs are not effective in identifying variation within species.

选择其中三组引子对(基因体位置为psbA~trnK、psbB~psbH及trnR-ACG~trnN-GUU)增幅片段之序列进行亲缘分析,以最大简约法及邻接法之分群结果皆与目前植物分类相符,故三组引子对在物种间亲缘关系分析及物种鉴定上都有不错的效果,位於psbA~trnK及psbB~psbH之引子对效果尤佳,但是三组引子对在物种内变异的辨识效果不甚理想,在两个毛豆品种间(高雄5号与高雄8号)、两个豇豆亚种间及三个水稻品种间(台农67号、台稉9号与台中秈10号)的增幅片段没有明显差异存在。

The result pointed out that the vertical distribution of foliage for each species was different,however,generally speaking,the foliage in upper crown (0.3CL) for broad-leaved species in natural secondary forest took a small percentage,about 10%;in middle or middle lower of the crown(0.4CL to 0.8CL) the branches here took the majority percentage of whole foliage,almost 60%to 75%;but in lower crown(0.8CL),there was about 10%of whole foliage.(5)The interspecies competition of trees in secondary forest was expressed by Hegyi competitioin index,and the active competitor was calculated by the competition zone radius and the tree position,DBH,and distance in the zone,it was not all competitors in tranditional calculation.The study introduced crown area overlap index to describe the crown competition between subject tree and its competitors,furthermore,the crown area was classified into 5 levels with a method of equal crown projection area,therefor,the resulting crown area overlap index showed more realities of existing stand conditons.(6)Based on the theoretics of multiply divide,the spatial strcture optimizing model of secondary forest stand selective thinning was developed by diversity mingling,aggregation index,competition index and crown area overlap index,also designed 10 constraint conditions which were related to forestry meanings,the objective function was solved by the implicit enumeration method with LINGO 9.0,using 0-1 integer programming.

并且得出,每个树种在树冠内相对高度上的叶量的垂直分布是不同的,天然次生林阔叶树种的叶量在树冠的上部(0.3CL以下)所占比例很小,约占10%左右;在树冠的中部以及中下部(0.4CL~0.8CL),叶量所占比例最大,几乎集中了整个树冠60%~75%的叶量;而在树冠的下部(0.8CL以下),几乎占很少的叶量,大约10%左右。5、采用Hegyi竞争指数来表现次生林内林木的竞争关系,并且根据竞争圈的大小和林木在竞争圈内的分布位置、大小与距离来计算有效的竞争木,并不是传统意义上的全部竞争木;本研究提出用树冠叠加指数来表示林木与周围树木的树冠竞争情况,并采用等树冠投影面积法把树冠分为5级,这样计算的树冠叠加指数更加与现实林分相符。6、本研究基于乘除法的思想,用多样性混交度、聚集指数、竞争指数和树冠叠加指数构建了天然次生林择伐空间优化模型,设计了10个与林学意义相一致的约束条件,并采用0-1整数规划的思路,在LINGO9.0软件中使用了隐枚举法对目标函数求得最优解。7、以M702标准地为应用实例,具体计算出了每株采伐木,经过择伐后,目标函数值按模型设计的要求发生了极大的改变,增加了5倍多,说明了最后这个解的优良性,满足了设计的要求。
