<think>嗯,用户现在遇到了Raspbian源公钥不可用的问题,具体是公钥9165938D90FDDD2E缺失。我需要帮他找到解决方法。首先,我得回忆一下在Debian或基于Debian的系统(比如Raspbian)中如何处理GPG密钥的问题。 根据用户提供的引用内容,特别是引用[1]和[2],看起来之前他们尝试过使用apt-key命令来导入公钥,但可能系统版本不同,比如现在Bullseye可能已经弃用了apt-key?因为我知道在Debian Bullseye之后,apt-key命令已经被弃用了,所以可能需要用另一种方法。不过用户提供的示例中用的是sudo apt-key adv...,但可能在Bullseye中需要将密钥添加到/etc/apt/trusted.gpg.d/目录下,而不是直接使用apt-key add。 接下来,步骤应该包括先更新软件包列表,然后下载缺失的公钥。可能需要用gpg命令直接下载密钥,然后将其转换为适合的格式,并放到指定目录。比如使用gpg --keyserver和--recv-keys选项来获取密钥,然后用gpg --export导出,并保存到/etc/apt/trusted.gpg.d/中。 另外,用户提到的错误信息显示在引用[3]中,是来自阿里云的镜像源,所以可能需要确认是否镜像源配置正确,或者是否需要更换镜像源。但用户的问题主要是添加缺失的公钥,所以重点应放在如何导入该密钥上。 现在,Debian Bullseye推荐的方法可能是将密钥文件放到/etc/apt/trusted.gpg.d/目录下,并使用gpg的导出功能。或者使用curl下载密钥并存储到指定位置。同时,可能需要使用gpg --export的参数将密钥转换为ASCII格式,比如使用armor选项。 可能的步骤是: 1. 使用gpg命令从keyserver.ubuntu.com获取公钥:gpg --keyserver keyserver.ubuntu.com --recv-keys 9165938D90FDDD2E 2. 导出公钥到文件:gpg --export --armor 9165938D90FDDD2E | sudo tee /etc/apt/trusted.gpg.d/raspbian-key.asc 3. 然后更新软件包列表:sudo apt update 或者,可能需要使用wget或curl直接下载密钥,比如使用类似下面的命令: sudo curl -fsSL http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x9165938D90FDDD2E | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/raspbian.gpg 然后更新。这样可能更直接。 但需要确认在Bullseye中是否支持这种方法。或者参考引用[5]中的例子,其中用了类似的步骤,但可能使用了临时文件。用户之前的引用中有使用apt-key adv的方法,但可能在Bullseye中已经不推荐,所以需要改用其他方法。 总结步骤应该是: - 下载公钥到系统可信密钥目录中 - 更新apt缓存 可能需要具体命令: 比如: sudo gpg --homedir /tmp --no-default-keyring --keyring /etc/apt/trusted.gpg.d/raspbian-key.gpg --keyserver keyserver.ubuntu.com --recv-keys 9165938D90FDDD2E 或者分步骤: 1. 下载密钥到临时文件: gpg --keyserver keyserver.ubuntu.com --recv-keys 9165938D90FDDD2E 2. 导出为ASCII格式: gpg --export --armor 9165938D90FDDD2E | sudo tee /etc/apt/trusted.gpg.d/raspbian-pubkey.asc 或者二进制格式: gpg --export 9165938D90FDDD2E | sudo tee /etc/apt/trusted.gpg.d/raspbian-pubkey.gpg > /dev/null 然后更新apt: sudo apt update 不过要注意权限和路径是否正确。另外,可能需要使用gpg的dearmor选项,如果密钥是ASCII armored的,可能需要转换。例如: curl -sSL "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x9165938D90FDDD2E" | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/raspbian-archive-key.gpg 这样应该可以正确下载并保存密钥。 然后用户运行sudo apt update应该就不会再报错了。另外,可能需要检查/etc/apt/sources.list中的源是否正确,是否使用了正确的镜像地址,比如阿里云的镜像是否支持Bullseye版本,或者是否需要更换镜像源。 不过用户的问题明确是要添加缺失的GPG公钥,因此重点应放在导入密钥的方法上。总结下来,正确的步骤应该是通过gpg获取密钥,导出到系统的受信任目录,然后更新。确保在Bullseye中使用正确的方法,不使用已弃用的apt-key。</think>### 解决方案:添加缺失的GPG公钥至Raspbian Bullseye系统 #### 步骤说明 1. **手动下载公钥** 通过`gpg`工具从Ubuntu密钥服务器获取公钥: ```bash gpg --keyserver keyserver.ubuntu.com --recv-keys 9165938D90FDDD2E ``` 若成功,终端会显示公钥导入信息[^2][^5]。 2. **导出公钥至系统可信目录** 将公钥转换为`.gpg`格式并保存到APT信任目录: ```bash gpg --export 9165938D90FDDD2E | sudo tee /etc/apt/trusted.gpg.d/raspbian-bullseye-key.gpg > /dev/null ``` 3. **更新软件源列表** 完成密钥添加后更新APT缓存: ```bash sudo apt update ``` #### 验证操作 若输出中不再出现`NO_PUBKEY 9165938D90FDDD2E`错误,表示公钥已生效[^3]。 #### 替代方法(直接下载) 若上述步骤失败,可通过`curl`直接下载密钥: ```bash sudo curl -fsSL "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x9165938D90FDDD2E" | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/raspbian-bullseye-key.gpg ``` --- ### 技术原理 - **GPG密钥作用**:验证软件包来源的真实性,防止篡改[^1]。 - **密钥服务器**:`keyserver.ubuntu.com`是Debian系发行版常用的公钥托管平台[^2]。 - **目录`/etc/apt/trusted.gpg.d`**:存储系统级可信密钥,替代旧版`apt-key`的推荐方式[^4]。 ---

研究Matlab影响下的神经数值可复制性

### Matlab代码影响神经数值可复制性 #### 标题解读 标题为“matlab代码影响-neural-numerical-replicability:神经数值可复制性”,该标题暗示了研究的主题集中在Matlab代码对神经数值可复制性的影响。在神经科学研究中,数值可复制性指的是在不同计算环境下使用相同的算法与数据能够获得一致或相近的计算结果。这对于科学实验的可靠性和结果的可验证性至关重要。 #### 描述解读 描述中提到的“该项目”着重于提供工具来分析不同平台下由于数值不精确性导致的影响。项目以霍奇金-赫克斯利(Hodgkin-Huxley)型神经元组成的简单神经网络为例,这是生物物理神经建模中常见的模型,用于模拟动作电位的产生和传播。 描述中提及的`JCN_2019_v4.0_appendix_Eqs_Parameters.pdf`文件详细描述了仿真模型的参数与方程。这些内容对于理解模型的细节和确保其他研究者复制该研究是必不可少的。 该研究的实现工具选用了C/C++程序语言。这表明了研究的复杂性和对性能的高要求,因为C/C++在科学计算领域内以其高效性和灵活性而广受欢迎。 使用了Runge–Kutta四阶方法(RK4)求解常微分方程(ODE),这是一种广泛应用于求解初值问题的数值方法。RK4方法的精度和稳定性使其成为众多科学计算问题的首选。RK4方法的实现借助了Boost C++库中的`Boost.Numeric.Odeint`模块,这进一步表明项目对数值算法的实现和性能有较高要求。 #### 软件要求 为了能够运行该项目,需要满足一系列软件要求: - C/C++编译器:例如GCC,这是编译C/C++代码的重要工具。 - Boost C++库:一个强大的跨平台C++库,提供了许多标准库之外的组件,尤其是数值计算相关的部分。 - ODEint模块:用于求解常微分方程,是Boost库的一部分,已包含在项目提供的文件中。 #### 项目文件结构 从提供的文件列表中,我们可以推测出项目的文件结构包含以下几个部分: - **项目树源代码目录**:存放项目的主要源代码文件。 - `checkActualPrecision.h`:一个头文件,可能用于检测和评估实际的数值精度。 - `HH_BBT2017_allP.cpp`:源代码文件,包含用于模拟霍奇金-赫克斯利神经元网络的代码。 - `iappDist_allP.cpp` 和 `iappDist_allP.h`:源代码和头文件,可能用于实现某种算法或者数据的分布。 - `Makefile.win`:针对Windows系统的编译脚本文件,用于自动化编译过程。 - `SpikeTrain_allP.cpp` 和 `SpikeTrain_allP.h`:源代码和头文件,可能与动作电位的生成和传播相关。 - **人物目录**:可能包含项目成员的简介、联系方式或其他相关信息。 - **Matlab脚本文件**: - `图1_as.m`、`图2_as.m`、`图2_rp`:这些文件名中的"as"可能表示"assembled",而"rp"可能指"reproduction"。这些脚本文件很可能用于绘制图表、图形,以及对模拟结果进行后处理和复现实验。 #### 开源系统标签 标签“系统开源”指的是该项目作为一个开源项目被开发,意味着其源代码是公开的,任何个人或组织都可以自由获取、修改和重新分发。这对于科学计算来说尤为重要,因为开放代码库可以增进协作,加速科学发现,并确保实验结果的透明度和可验证性。 #### 总结 在理解了文件中提供的信息后,可以认识到本项目聚焦于通过提供准确的数值计算工具,来保证神经科学研究中模型仿真的可复制性。通过选择合适的编程语言和算法,利用开源的库和工具,研究者们可以确保其研究结果的精确性和可靠性。这不仅有助于神经科学领域的深入研究,还为其他需要高精度数值计算的科研领域提供了宝贵的经验和方法。

Leaflet.Graticule插件:创建经纬度网格刻度

标题“Leaflet.Graticule:经纬线网格”指向的是Leaflet.js的一个插件,它用于在地图上生成经纬度网格线,以辅助进行地图定位与参考。从描述中,我们可以提取到几个关键知识点: 1. Leaflet.Graticule插件的使用目的和功能:该插件的主要作用是在基于Leaflet.js库的地图上绘制经纬度网格线。这可以帮助用户在地图上直观地看到经纬度划分,对于地理信息系统(GIS)相关工作尤为重要。 2. 插件的构造函数和参数:`L.graticule(options)`是创建Graticule图层的JavaScript代码片段。其中`options`是一个对象,可以用来设置网格线的显示样式和间隔等属性。这表明了插件的灵活性,允许用户根据自己的需求调整网格线的显示。 3. interval参数的含义:`interval`参数决定了网格线的间隔大小,以度为单位。例如,若设置为20,则每20度间隔显示一条网格线;若设置为10,则每10度显示一条网格线。这一参数对于调节网格线密度至关重要。 4. style参数的作用:`style`参数用于定义网格线的样式。插件提供了自定义线的样式的能力,包括颜色、粗细等,使得开发者可以根据地图的整体风格和个人喜好来定制网格线的外观。 5. 实例化和添加到地图上的例子:提供了两种使用插件的方式。第一种是直接创建一个基本的网格层并将其添加到地图上,这种方式使用了插件的默认设置。第二种是创建一个自定义间隔的网格层,并同样将其添加到地图上。这展示了如何在不同的使用场景下灵活运用插件。 6. JavaScript标签的含义:标题中“JavaScript”这一标签强调了该插件是使用JavaScript语言开发的,它是前端技术栈中重要的部分,特别是在Web开发中扮演着核心角色。 7. 压缩包子文件的文件名称列表“Leaflet.Graticule-master”暗示了插件的项目文件结构。文件名表明,这是一个典型的GitHub仓库的命名方式,其中“master”可能代表主分支。通常,开发者可以在如GitHub这样的代码托管平台上找到该项目的源代码和文档,以便下载、安装和使用。 综上所述,可以得知,Leaflet.Graticule插件是一个专为Leaflet地图库设计的扩展工具,它允许用户添加自定义的经纬度网格线到地图上,以帮助进行地图的可视化分析。开发者可以根据特定需求通过参数化选项来定制网格线的属性,使其适应不同的应用场景。通过学习和使用该插件,可以增强地图的交互性和信息的传递效率。

51小车循迹红外

基于51单片机的红外循迹小车的实现方法,主要涉及硬件连接、传感器模块的使用以及程序设计三个方面。 ### 红外循迹模块的选择与连接 红外循迹模块通常由多个红外发射和接收对管组成,用于检测地面上的黑线。常见的模块有四路红外循迹模块,其工作原理是通过检测红外光的反射强度来判断是否处于黑线上。红外模块的VCC和GND分别连接到51单片机的+5V和GND端,而IN1至IN4则连接到单片机的对应引脚上。红外发射接收器应安装在小车前方下端,并且离地面的距离不宜过远,以确保能够有效检测到黑线[^2]。 ### 硬件电路设计 在硬件设计方面,需要考虑电机驱动、电源管理、以及红外传感器的接口设计。51单片机

AMEF图像去雾技术:Matlab实现与应用

AMEF(Artificial Multi-Exposure Fusion)方法是一种用于图像去雾的技术,其核心思想是将多张曝光不足的图像融合成一张清晰无雾的图片。在讨论这个技术的Matlab实现之前,让我们先了解图像去雾和多重曝光融合的背景知识。 图像去雾技术的目标是恢复在雾中拍摄的图像的清晰度,增强图像的对比度和颜色饱和度,使得原本因雾气影响而模糊的图像变得清晰。这种技术在自动驾驶、无人机导航、视频监控、卫星图像处理等领域有着重要的应用。 多重曝光技术源自摄影领域,通过拍摄同一场景的多张照片,再将这些照片通过特定算法融合,获得一张综合了多张照片信息的图像。多重曝光融合技术在提高图像质量方面发挥着重要作用,例如增加图片的动态范围,提升细节和亮度,消除噪点等。 在介绍的AMEF去雾方法中,该技术被应用于通过人工创建的多重曝光图像进行融合,以产生清晰的无雾图像。由于单一图像在光照不均匀或天气条件不佳的情况下可能会产生图像质量低下的问题,因此使用多重曝光融合可以有效地解决这些问题。 在Matlab代码实现方面,AMEF的Matlab实现包括了一个名为amef_demo.m的演示脚本。用户可以通过修改该脚本中的图像名称来处理他们自己的图像。在该代码中,clip_range是一个重要的参数,它决定了在去雾处理过程中,对于图像像素亮度值的裁剪范围。在大多数实验中,该参数被设定为c=0.010,但用户也可以根据自己的需求进行调整。较大的clip_range值会尝试保留更多的图像细节,但同时也可能引入更多噪声,因此需要根据图像的具体情况做出适当选择。 AMEF方法的理论基础和实验过程均来自于Adrian Galdran在2018年发表于《信号处理》期刊的文章,题为“Image Dehazing by Artificial Multi-Exposure Image Fusion”。同时,该Matlab代码的融合部分的理论基础则来自于2007年Pacific Graphics会议记录中由Tom Mertens, Jan Kautz和Frank Van Reeth提出的工作,题目为“Exposure Fusion”。因此,如果读者在实际应用中使用了这段代码,适当的引用这些工作是必要的学术礼仪。 此外,标签“系统开源”表明了该项目遵循开源精神,允许研究者、开发者及用户自由地访问、使用、修改和共享源代码。这一特点使得AMEF方法具有广泛的可访问性和可扩展性,鼓励了更广泛的研究和应用。 从压缩包子文件的文件名称列表中,我们可以看到AMEF去雾方法的Matlab实现的项目名为“amef_dehazing-master”。这表明了这是一个有主分支的项目,其主分支被标识为“master”,这通常意味着它是项目维护者认可的稳定版本,也是用户在使用时应该选择的版本。 总的来说,AMEF去雾方法及其Matlab实现为图像处理领域提供了快速且有效的解决方案,能够在图像被雾气影响时恢复出高质量的清晰图像,这对于相关领域的研究和应用具有重要的意义。
