Results of cultural characters show that Grifola frondosa has different macroscopic arid microscopic culture characteristics on different media, and the mycelia on PDA medium and half-combined PDA medium can produce extracellular phenol oxidase, indicating that G. frondosa is a kind of white-rot fungus. On PDA medium and half-combined PDA medium, hyphae with thick colonies, dense, white, villiform to flocky, grow very well, but aerial hyphae grow faintly and loosely on MEA medium.

培养特性的研究结果表明，灰树花在不同的培养基上宏观和微观培养特性各有不同：菌体在PDA和马铃薯半组合培养基上都能够产生细胞外酚氧化酶，说明灰树花是一种白腐菌；菌丝在PDA和马铃薯半组合培养基上生长旺盛，浓密，白色，绒毛状至絮状，菌落厚；在MEA培养基上生长较弱，气生菌丝体较稀疏。

Lepidopterainsectsincluded11families,morethan 30 species of moths,such as Noctuidae(relative number percentage of Lepidopterainsects36.6%),Sphingidae(24.1%),Geometridae(13.4%)and Limacodidae(9.5%). Thelength of forewings ranged from 5—40mm(99.5%) and 60—65mm(0.5%). The result ofPearson correlation analysis showed that foraging of Rhinolophus ferrumequinum might beselective, not random. 2. Foraging tactics mostly included two ways: aerial hawking during the period of thepeak of insects activity and flycatching during the insects' non-peak activity period.

马铁菊头蝠所捕食的鳞翅目昆虫包括 11 科 30余种蛾，主要以夜蛾科Noctuidae(占所捕食的鳞翅目昆虫的数量百分比为36.6%)、天蛾科Sphingidae(24.1%)、尺蛾科Geometridae(13.4%)和刺蛾科Limacodidae(9.5%)为主，捕食的鳞翅目昆虫前翅翅长介于 5—40mm(数量百分比为 99.5%)之间和 60—65mm 之间(0.5%) Pearson 相关分析表明马铁菊头蝠在捕食过程中不是随机捕食，而。

It was found that the fungus 1403 resembles pathogenic F. verticillioides (teleomophy Gibberella moniliforme) in the production of false head or chains and abundant microconidia on the aerial mycelium, but different in the occasional formation of polyphialides with relatively long as well as short monophialides, in its typical coiled hyphae and mycelia fusion.

基于1403在形态学方面具有以下特征：产小型分生孢子的分生孢子梗较长，小型分生孢子呈椭圆形，大型分生孢子线形或略微弯曲，本文将它与有类似形态特征的镰刀菌进行了比较，发现1403与植物病原菌Fusarium verticillioides（有性态为Gibberella moniliforme）表面上很相似，气生菌丝均可产生大量假头状或链状的小型分生孢子，但深入的研究却发现1403与F。

目的：为白子菜药材地上部分的品质评价及其活性成分的开发利用提供实验依据，以利于更全面地对该药材进行质量控制。

In this paper,we use direct linear transformation algorithm to compute the homographic matrix between the known ground control points with equal elevation and the corresponding points on the image plane, then establish the relationships between the homographic matrix and the collinearity equations, and finally give the mathematic models for computing the intrinsic and extrinsic parameters of the aerial camera.

该方法根据单张航空像片估计伞载空中摄像机焦距及摄像机在世界坐标系中的位置和姿态角等外参数，利用直接线性变换算法求取已知等高地面控制点与对应像点之间的单应矩阵，建立了单应矩阵与共线条件方程之间的关联关系，最后根据关联关系推导出计算航空摄像机焦距、纵横比、位置和姿态角等内外参数的数学模型。
