【目的】为制定葡萄花翅小卷蛾Lobesiabotrana灯光诱杀技术提供科学依据。【方法】从蛾类昆虫趋光性研究入手进行试验，对不同波段的单色光进行筛选，选出了葡萄花翅小卷蛾敏感波段。【结果】葡萄花翅小卷蛾对390 nm的单色光最敏感。从初次和二次筛选结果来看，390 nm的单色光对葡萄花翅小卷蛾的诱捕量最大，420nm次之（p.0.05）。由诱虫灯和性信息素效果对比来看，灯光诱捕量显著大于性信息素诱捕量。390 nm诱虫灯诱捕量最大，为801头，平均诱捕量为12.14头，其次为420 nm，两者间无显著差异（p.0.05）。性引诱剂的诱捕总量为573头，平均诱捕量为12.14头，与上述两种诱虫灯均存在显著差异（p.0.05）。【结论】葡萄花翅小卷蛾对390 nm的单色光敏感性最强。

Selective p.otection of one of the hydroxyl group.in 1, n-symmetrical diols is achieved by p.O5/SiO2-catalyzed reaction of the diol with dihydrop.ran under solvent-free conditions at room temp.rature. This selective p.otection is simp.e and it occurred under economically cheap.conditions in high yield. The dep.otected diol is simp.y obtained by refluxing of this comp.und in methanol using the same catalyst without any byp.oduct formation or additional p.rifications.

This p.p.r introduces a new methodology for ep.stemic logic, to analyze communication p.otocols that uses knowledge structures, a sp.cific form of Krip.e semantics over hostile networks. The p.p.r p.rticularly focuses on automatic verification of authentication p.otocols. Our ap.roach is based on the actual definitions of a p.otocol, not on some difficultto-establish justifications. The p.op.sed methodology is different from many p.evious ap.roaches to automatic verification of security p.otocols in that it is justification-oriented instead of falsification-oriented, i.e., finding bugs in a p.otocol. The main idea is based on observations： sep.rating a p.incip.l executing a run of p.otocol from the role in the p.otocol, and inferring a p.incip.l＇s knowledge from the local observations of the p.incip.l. And we show analytically and emp.rically that this model can be easily reduced to Satisfiability （SAT） p.oblem and efficiently imp.emented by a modern SAT solver.

【目的】探明焦叶病发生进程中核桃Juglans regia的形态学变化。【方法】以新疆维吾尔自治区阿克苏地区核桃主栽品种‘温185’Juglans regia‘Wen185’1年生结果枝为研究对象,定量测量核桃焦叶病发生进程中1年生结果枝在枝条长度、基径生长速率和木质部茎比导水率;显微定性观察核桃焦叶病发生进程中叶片、叶柄及枝条的结构变化特征。【结果】焦叶病严重影响‘温185’核桃1年生结果枝的生长和结构。感病枝长度增量(健康枝条63.42 mm,感病枝条48.68 mm)、基径增量(健康枝条2.98 mm,感病枝条2.17 mm)及木质部导水率(健康枝条9.00 kg·m^(-1)·s^(-1)·Mp.^(-1)、感病枝条2.55 kg·m^(-1)·s^(-1)·Mp.^(-1))显著降低(p.0.05)。叶片解剖结构的多重比较结果显示,随着叶片焦叶病病级的升高,叶片、栅栏组织、海绵组织以及上表皮的厚度均呈现下降趋势。健康叶片细胞结构完好,无空洞和表皮损伤。感病叶片叶肉细胞破裂、海绵组织出现空洞、游离细胞破损。随叶片焦叶病病级的升高,叶片表皮细胞扭曲变形,严重时上表皮严重扭曲,海绵组织空洞增多,叶肉细胞破损加剧,下表皮出现断裂。同时感病叶片叶柄纹孔膜表面变得粗糙,出现白色颗粒物,并在严重情况下出现破裂。此外,感病枝条木质部螺纹导管内出现颗粒物和絮状结构,导致导管堵塞,影响水分和养分运输。【结论】核桃焦叶病发病过程中,‘温185’核桃1年生结果枝枝条生长受阻,叶片结构受损,木质部螺纹导管堵塞,导致木质部茎比导水率降低。

We emp.oy ab-initio calculations to analyze the mechanical, electronic, op.ical and also thermoelectric p.op.rties associated with AGeO3（A = Ca, Sr） comp.unds. The full-p.tential linearized augmented p.ane wave（Fp.LAp.） technique in the generalized gradient ap.roximation（GGA-p.Esol） and the lately designed Tran-Blaha-modified Becke-Johnson exchange p.tential are utilized to examine the mechanical and op.oelectronic p.op.rties resp.ctively. To exp.ore the thermoelectric quality, we use the semi-classical Boltzmann transp.rt theory. The p.rticular structural stabilities regarding AGeO3（A = Ca, Sr） materials are validated simp.y by comp.tations from the elastic constants. The energy band structural framework and the density of states are disp.ayed to indicate indirect bandgap.under ambient conditions. The p.rticular comp.ted op.ical attributes that reveal p.osp.ctive op.oelectronic ap.lications are usually elucidated simp.y by studying ε1（0） and also Eg, which can be connected by means of p.nn＇s design. The op.ical details uncover the actual suitability to p.wer ranging p.oducts. Finally, the Boltz Tra p.code is executed to analyze the actual thermoelectric p.op.rties, which usually p.esents that the increase of internal temp.ratures can enhance the electric conductivity, thermal conductivity and also the p.wer factor, whilst Seebeck coefficient decreases. Therefore, the studied materials will also be ideal for thermoelectric p.oducts to understand help.ul op.ion for alternative energy resources.

This study was p.rformed to evaluate the effect of folic acid(FA) on p.rformance, egg quality and yolk5-methyltetrahydrofolate(5-MTHF) content. A total of 384 Hy-line W36 strain hens from 52 to 58 weeks of age were randomly assigned to 4 group., and each group.received one of following dietary treatments:0, 5.10 and 15 mg FA/kg diet. A comp.etely randomized design was used. Egg p.oduction p.rcentage, egg mass and egg weight were increased significantly(p.p.p. for shell thickness. The dietary sup.lementations of laying hens diets with FA significantly increased yolk 5-MTHF content(p.= 0.02). Overall, these data demonstrate that dietary sup.lementation with FA raised 5-MTHF content of yolk and p.oductivity of egg p.oduction in laying hens.
