本文将注意力机制分类模型——Vision Transformer(ViT)应用于树种分类识别任务,旨在探索更高精度和更高效率的树种识别模型。本研究共设计了三组对比实验:(1)用ViT和resNet50在实验环境的数据集上进行训练、验证和测试,(2)为Vi T模型设置不同的深度进行训练,(3)用ViT和resNet50在真实环境的数据集上进行训练、验证和测试。结果表明,无论是实验环境的数据集,还是真实环境的数据集,ViT模型都达到了与resNet50模型相当的分类性能,并且ViT模型的时间效率明显优于resNet50。此外,本研究还展示了Vi T对真实环境的图像进行分类时的类激活热力图,发现ViT模型更关注树叶本身尤其是树叶边缘而忽略了复杂的背景,从而有效提高了分类精度。结果说明,两个模型分类精度相当,但ViT的收敛速度明显更快,学习特征的能力更强,泛化能力也更强。本研究是将ViT应用在树种分类识别这一具体任务上的一次有益尝试,为后续融合ViT与CNN优势,以更高的效率、更小的数据需求、在更复杂的高原林业数据集上进行树种识别研究奠定基础。

为了明确谷胱甘肽(GSH)对多年生黑麦草铅(pb)毒害的缓解作用及其生理机制,以12周龄多年生黑麦草‘卡特’幼苗为试验材料,设置4个试验处理:1)根部置1/2 Hoagland营养液,叶面喷蒸馏水50 mL(CK);2)根部置含0.75 mmol·L^(-1)pb(NO_(3))_(2)的1/2 Hoagland营养液,叶面喷蒸馏水50 mL(pb);3)根部置含0.75 mmol·L^(-1)pb(NO_(3))_(2)的1/2 Hoagland营养液,叶面先喷25 mL蒸馏水,待吸收后再喷施25 mL 10 mmol·L^(-1)GSH(pb+GSH);4)根部置含0.75 mmol·L^(-1)pb(NO_(3))_(2)的1/2 Hoagland营养液,叶面先喷25 mL蒸馏水,待吸收后再喷施25 mL 1 mmol·L^(-1)丁硫氨酸-亚砜亚胺(BSO)(pb+BSO),研究GSH对多年生黑麦草生长及光合作用的影响。结果表明:叶面喷施GSH显著增加了幼苗茎叶长、根长、分蘖数、生物量、叶绿素含量和光合参数,也增加了叶绿素荧光动力学参数。叶面喷施BSO后,根长、分蘖数、生物量、类胡萝卜素含量和光合参数均降低。综上所述,pb胁迫影响了光合作用,最终抑制了植物的生长。叶面喷施10 mmol·L^(-1)GSH能够缓解pb对多年生黑麦草生长和光合作用的胁迫,提高植物的抗性。相反,叶面喷施1 mmol·L^(-1)BSO能够加剧pb对植物的胁迫。

保水剂常应用于干旱半干旱区的砂土中以提高土壤持水性能。干湿交替会削弱保水剂的耐用性,但干湿交替如何影响添加保水剂的砂土的持水性能的研究较少;因此,作者以添加保水剂砂土为研究对象,利用模拟土柱试验方法,设置保水剂类型、保水剂用量和干湿交替次数等因素进行实验,研究干湿交替对添加保水剂的砂土持水性能的影响。结果表明:1)分别添加低中高3种用量的丙烯酰胺丙烯酸盐共聚交联物保水剂、聚丙烯酸/凹凸棒复合保水剂、聚丙烯酰胺型保水剂的砂土,其饱和含水率以及孔隙度提高,Gardner模型参数a提高,累计蒸发量减少。且保水剂用量越多,影响程度越大,其中含用量为6 g/kg的丙烯酰胺丙烯酸盐共聚交联物类保水剂的砂土持水性能最优。2)经过干湿交替后,添加保水剂的砂土的饱和含水率以及孔隙度减少、持水性能和抑制水分蒸发效果削弱。干湿交替后,含高用量的3类保水剂的砂土持水性能削弱效果均大于含低用量的3类保水剂的砂土持水性能削弱效果。3)含保水剂的砂土在1~3次干湿交替过程中,速效水含量增加;3~6次干湿交替后,速效水含量减少。10次干湿交替后持水性能仍优于未添加保水剂的砂土。由此可见,干湿交替会削弱保水剂对砂土持水性能的改良效果,但保水剂仍具有一定的使用价值。

了解不同光强对小×胡杨气体交换参数的影响,可为进一步评价小×胡杨新品种适应性提供基础数据,为乌兰布和沙漠东北部防护林体系的更新及造林树种选择提供一定的理论依据。利用Li-6400xt便携式光合仪测定了不同光强下小×胡杨的光合生理参数,利用非直角双曲线模型,拟合植物叶片净光合速率(pn)与光合有效辐射(pAr)的关系,计算光饱和速率(Amax),光饱和点(LSp),光补偿点(LCp),表观量子效率(AQY),暗呼吸效率(rD)等光合生理参数。结果表明,在光合有效辐射(pAr)0~1500μmol·m^(-2)·s^(-1)范围内,不同栽植年限小×胡杨净光合速率均随着光合有效辐射(pAr)的增强而增加,当光合有效辐射(pAr)为1500μmol·m^(-2)·s^(-1)时,曲线处于缓慢上升趋势,小×胡杨还没有达到光饱和点。不同光合有效辐射,净光合速率值均表现为3年>2年>1年生,1年、2年、3年生小×胡杨之间的净光合速率差异显著(p3年生小×胡杨的光饱和速率(Amax)、光饱和点(LSp)、光补偿点(LCp)、表观量子效率(AQY)最高。1年生小×胡杨的暗呼吸速率最大,3年小×胡杨的暗呼吸速率最小。在光合有效辐射(pAr)0~1500μmol·m^(-2)·s^(-1),不同栽植年限小×胡杨气孔导度(Gs)均随光合有效辐射(pAr)的增加而增加,而胞间CO2浓度(Ci)均呈逐步下降的趋势;随着有效光辐射的逐步增强,不同栽植年限小×胡杨蒸腾速率逐渐增加,变化趋势都较缓慢平稳,蒸腾速率对光合有效辐射(pAr)的变化并不敏感。当光合有效辐射2)·s^(-1),1年、2年、3年生小×胡杨水分利用效率增加迅速,当光合有效辐射>600μmol·m^(-2)·s^(-1),随着光强的增强,3年生小×胡杨水分利用效率继续缓慢上升,但1年、2年生的小×胡杨水分利用效率趋于平缓甚至下降。综合分析,1年、2年、3年生小×胡杨具有高光合,高水分利用效率和相对较低的蒸腾速率的特点,表现出了对当地生态气候的良好适应性。

慢性炎症性疼痛以周围敏化为主要表现形式,藏族药经典外用方剂白脉软膏治疗慢性炎症性疼痛临床疗效确切,但其缓解周围敏化的药效学及机制尚不明确。该研究拟建立完全弗氏佐剂诱导的慢性炎症性疼痛动物模型,并采用行为学检测、副作用评估、网络分析及实验验证等方法探讨白脉软膏治疗慢性炎症性疼痛的药效及机制。药效学研究表明白脉软膏可剂量依赖性提高慢性炎症性疼痛小鼠致炎足机械痛敏及热辐射痛敏阈值且无耐受性,对足肿胀、炎症介质及TrpV1、TrpA1的表达也有明确的抑制作用;体质量监测、正常小鼠痛敏阈值检测、轮替、强迫游泳实验等结果显示白脉软膏无明显毒副作用;根据白脉软膏基原药材药效、主要成分含量、ADME参数等纳入的51个候选活性分子网络分析显示,白脉软膏对慢性炎症性疼痛的抑制作用与调节TNF、T细胞受体信号通路核心调控元件相关;进一步实验研究表明,白脉软膏可有效下调小鼠足跖部组织MApK14、MApK1、pTGS2的蛋白表达,并上调GSK3B的磷酸化水平。综上,白脉软膏可有效缓解慢性炎症性疼痛的周围痛敏且无耐受性及明显的毒副作用,相关机制可能与白脉软膏调控周围组织TNF及T细胞受体信号通路的核心调控元件相关。

JUNO is a multi-purpose neutrino observatory under construction in the south of *** publication presents new sensitivity estimates for the measurement of the △m_(31)^(2),△m_(21)^(2),sin^(2)θ_(12),and sin^(2)θ_(13) oscillation parameters using reactor antineutrinos,which is one of the primary physics goals of the *** sensitivities are obtained using the best knowledge available to date on the location and overburden of the experimental site,the nuclear reactors in the surrounding area and beyond,the detector response uncertainties,and the reactor antineutrino spectral shape constraints expected from the TAO satellite *** is found that the △m_(21)^(2) and sin^(2)θ_(12) oscillation parameters will be determined to 0.5%precision or better in six years of data *** the same period,the △m_(31)^(2) parameter will be determined to about 0.2%precision for each mass ordering *** new precision represents approximately an order of magnitude improvement over existing constraints for these three parameters.
