Electroantennogram responses by mountain pine beetles,Dendroctonus ponderosae Hopkins,exposed to selected semiochemicals

Electroantennograms (EAGs) were obtained forD. ponderosae to the bark beetle pheromonestrans-verbenol,cis-verbenol,exo-brevicomin,endo-brevicomin, frontalin, verbenone; to the kairomones, -pinene, -pinene, camphene, -3-carene, limonene, myrcene; to a blend (111) oftrans-verbenol,exo-brevicomin, and myrcene; and to diacetone-alcohol. Male and female responses, in general, did not differ significantly over the whole EAG dose-response curves but differed at a few concentrations on many of the curves. There were more differences noted for pheromones than kairomones. The blend yielded among the largest EAGs in both sexes and appeared to show synergism. Responses of females were lower than those for males in most instances. Significant differences in responses by the two sexes were much fewer for the kairomones than the pheromones. EAG recovery rates tested at only one concentration showed significant differences between males and females for three pheromones,trans-verbenol,cis-verbenol, and verbenone, and two kairomones, camphene and -3-carene. Thresholds were quite low for most of the odorants exceptcis-verbenol, camphene, verbenone, and diacetone-alcohol in females, andcis-verbenol, verbenone, -pinene, and diacetone-alcohol in males. The results, using at least one EAG parameter, support behavioral and field studies involvingexo-brevicomin,trans-verbenol, frontalin, and the blend.     

青海阿尔茨托山铜铅锌多金属矿床地质特征及找矿方向

青海阿尔茨托山铜铅锌多金属矿床处于柴北缘铅锌银铜金多金属成矿带东段,分东沟和吉给申两个矿床,矿床受上奥陶统滩涧山群(O3tn)地层控制.文章介绍了矿床地质特征及成因,矿床为早期的热水沉积—变质型叠加了后期接触交代的复合成因铜铅锌多金属矿床,分热水沉积、变质作用、接触交代3个成矿期,结合已有的地质资料,提出了该区找矿标志,指出下步的找矿方向,认为该区找矿潜力大,除重视铜铅锌成矿元素外,还应考虑钨锡找矿.

Application of spherical-rod float image velocimetry for evaluating high flow rate in mountain rivers

Spherical-rod float image velocimetry (SFIV) is a convenient technique combining the positive functions of a rod float velocimetry (RFV) and large-scale particle image velocimetry (LSPIV) for measuring high flow rate in mountain rivers. The SFIV is the principle that the sphere allowing little image distortion according to the orientation is used as a floating tracer for LSPIV. The drifting distances of a spherical-rod float were calculated by geometrical interpretation of spherical images recorded in an experimental open channel and mountain rivers. The depth-reflecting velocities estimated by SFIV in the rivers as in the open channel coincided approximately with the velocities by visual observation from river bank despite of the long shooting distance, weather impact, and flow complicated by topography and bed materials. The velocity coefficients obtained from the experimental channel were used to evaluate depth-averaged velocity for river discharges. The high discharges estimated by SFIV in mountain rivers distributed mostly within the range of the rating curve established by RFV. The results show that the safe and efficient SFIV is a highly applicable technique in mountain rivers with the high flow rate and complex flow. In order to practically use SFIV in mountain rivers, additional studies are required for velocity coefficients depending on the water depth and draft.     

基于“公共性”视角的闽中防御性乡土建筑空间特征解析

寨堡是福建环戴云山地区村民、乡族 大量兴建的大型集合式、防御性乡土建筑,应 对明清时期社会动乱以保障生命财产安全的 时代产物。通过历史文献查阅和田野调查参证 可知：寨堡的公共性是以营建方式和产权归属 为依据,通过地缘契约合作、血缘氏族共建和 官方推崇把制,明显具有地缘和血缘结合的特 征;进而通过防御、仪式和教育等公共事务组 织,加强巩固乡权、族权、神权三权合一的集中 控制形式。基于此,分别从建造规模、防御工 事、空间布局等方面分析闽中大田、尤溪和永泰 地区寨堡公共空间的地域性特征和区别。以期 对乡土建筑文化遗产的价值认识和保护传承具 有借鉴意义。     

谈诗

诗论是冯纪忠先生学术思想的重要组成部分。该文是冯先生2007年7月就屈原《九歌·山鬼》、刘邦《大风歌》、柳宗元《江雪》、《渔翁》、《与浩初上人同看山寄京华亲故》、杜牧《山行》所做的讲谈实录,对诗的体会饱含了冯先生自己的人生体悟。各篇论述要点依次如下:1通过对祭祀中巫唱、觋唱及陪唱的区分,疏理了《九歌·山鬼》主词的逻辑关系,给出了自己独特的解读;2通过对刘邦流氓本性的揭示,批判了刘邦《大风歌》中暴露的专制思想;3结合柳宗元本人的历史及所处环境的研究对三首诗给出了自己的阐述;4分析了杜牧诗作描写风景的画面感的特征。
