当为深度偏移建立三维的速度—深度模型时,必须克服两个基本的问题:①模型的数学表达式必须足够灵活,可以适当描述地层的复杂性;②建立深度模型所需的用户界面必须简单。然而,这两个问题的解决又似乎是相互对立的。一般地讲,当模型表达的灵活性增大时,则用户界面的复杂程度也增大。让我们更详细地考察一下这两个问题。

The bird cherry-oat aphid (rhopalosiphum padi [Linnaeus, 1758]) is considered a key pest of cereal crops worldwide, causing direct damage through sap feeding and by acting as a vector for viral diseases. Managing aphids is challenging because of their biology and potential resistance to insecticides. Developing resistant barley genotypes is a sustainable strategy for managing BCOA. In this study, we assessed responses of susceptible “Morex” and resistant “BCO r001” barley, Hordeum vulgare L. genotypes to different initial BCOA densities (0, 50, 100 or 200 ***p>-1p>). physiological and morphological p.r.meters were measured weekly for four weeks after infestation. Chlorophyll content, photosynthetic rate, plant aerial fresh and dry weight were greater for the resistant cultivar at lower aphid abundances and up to three weeks after infestation. Carbon assimilation curves (A/Ci) of infested “BCO r001” were similar to controls 15 days post infestation, differing from Morex. However, BCOA infestation of 50 ***p>-1p> for two weeks negatively impacted the fitness of both genotypes. Initial resistance by BCO r001 to BCOA infestation can allow growers and natural enemies more time contributing to more effective and sustainable management of BCOA infestations.

黑光试验检测黄曲霉毒素污染的可靠性

国外畜牧学（猪与禽） 1989年第3期9卷 25-26页

作者：汝劲 r.D.wyatt 美国乔治亚大学家禽科学系

饲料的霉菌毒素污染是饲料或谷物的质量问题.如果未能查出这种污染,并且使用了污染饲料,就可能导致畜禽生产的重大问题。饲料的污染和检测举例来说,1977年美国东南部在玉米生长季节中的条件(温度、雨量、虫害等)都有利于黄曲霉和寄生曲... 详细信息

饲料的霉菌毒素污染是饲料或谷物的质量问题.如果未能查出这种污染,并且使用了污染饲料,就可能导致畜禽生产的重大问题。饲料的污染和检测举例来说,1977年美国东南部在玉米生长季节中的条件(温度、雨量、虫害等)都有利于黄曲霉和寄生曲霉的生长,结果该地区收获的玉米中约80%污染了黄曲霉毒素.而且,这一年平的均污染水平超过400ppb(10亿分之400).这一罕见的高水平黄曲霉毒素污染导致养禽业出现了各种生产问题.

High power Laser Science and Engineering 2017年第3期5卷 62-66页

作者： C.Spindloe D.wyatt S.Astbury G.F.Swadling T.Clayson C.Stehlé J.M.Foster E.Gumbrell r.Charles C.N.Danson p.Brummitt F.Suzuki-Vidal Current address： Lawrence Livermore National Laboratory California 94550 USA

This pap.r.describes the design and fabrication of a range of ‘gas cell' microtargets produced by the Target Fabrication Group in the Central Laser Facility(CLF) for academic access exp.r.ments on the Orion laser facility at the Atomic Weapons Establishment(AWE). The exp.r.ments were carried out by an academic consortium led by Imp.r.al College London. The underlying target methodology was an evolution of a range of targets used for exp.r.ments on radiative shocks and involved the fabrication of a precision machined cell containing a number of ap.r.ures for interaction foils or diagnostic windows. The interior of the cell was gas-filled before laser irradiation. This pap.r.details the assembly processes, thin film requirements and micro-machining processes needed to produce the targets. Also described is the implementation of a gas-fill system to produce targets that are filled to a pressure of 0.1–1 bar. The pap.r.discusses the challenges that are posed by such a target.

本文考虑共享单车迁移问题,它可看作是经典旅行售货商问题的一个新颖变形,不同的是其目标函数为最小化碳排放。其中,碳排放利用单车负载与其行驶路程的乘积进行刻画。我们提出了两个启发式算法:贪心和基于TSp的算法,每个算法的核心思想均是优先减少单车负载。从理论上证明算法的可行性并给出数据实验以验证算法的实际性能。数据实验结果表明贪心算法优于基于TSp的算法,这为共享单车企业进行日常单车分配提供了理论依据。
