Occurrence and Integrated Control of Disease and Pests of Orchard in Wangdonggou Watershed

长武王东沟杏园虫害为李小食心虫、桑白蚧 ,病害为杏疔病 ,苹果树上的害虫为桃小食心虫。李小在杏园中4月中旬出土 ,6月初达到为害高峰期 ,桑白蚧 5月上旬为卵孵化高峰期 ,桃小食心虫越冬代幼虫出土高峰期在 6月 7日左右 ,第一代幼虫孵化高峰期在 6月 2 5日到 7月 1日之间 ,第二代幼虫孵化高峰期发生在 8月 15日左右。在防治上主要抓住越冬幼虫出土期、幼虫脱果期、幼虫孵化期进行地面喷药和树上喷药 ,同时结合成虫诱杀、套袋等措施。对杏疔病的防治采取人工销毁病枝和药剂防治的办

均匀目标表面缺陷检测灰度照度补偿方法

本发明专利涉及基于均匀目标表面缺陷检测的光照补偿方法。其步骤为：首先利用标定的工业相机对检测目标进行图像采集；其次对图像平均预处理，降低单个亮点和暗点产生的局部噪声；再次分别进行行平均和列平均处理，获得行平均曲线和列平均曲线；然后对多幅图像并获得多个行平均曲线和列平均曲线进行平均值处理，进而获得平滑的行平均曲线和列平均曲线；对平滑的灰度平均值进行归一化处理，然后基于归一化值进行插值处理，可以获得基于此光照条件下的连续平滑的理想模型灰度图像模型；利用最大灰度值图像与插值后的理想灰度图像差值获得光照补偿模板。本发明方法可以有效补差光照不均匀的图像灰度，为后续处理提供更接近光照均匀的优质图像

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
