74hc139中文资料参数

74hc139中文资料参数M74HC139/74HC139 功能:2 线—4 线译码器M74HC139/74HC139 用于高性能的存贮译码或要求传输延迟时间短的数据传输系统,在高性能存贮器系统中,用这种译码器可以提高译码系统的效率。

将快速赋能电路用于高速存贮器时,译码器的延迟时间和存贮器的赋能时间通常小于存贮器的典型存取时间,这就是说由肖特基钳位的系统译码器所引起的有效系统延迟可以忽略不计。

HC139含有两个单独的2 线—4 线译码器,当赋能输入端G为高电平时,按二进制控制输入码从4 个输出端中译出一个低电平输出。

在解调器应用中,低电平有效的赋能输入端用作数据线。

铝合金应力腐蚀开裂ASTM G139(中文翻译版)

用断裂负荷法测定热处理铝合金制品抗应力腐蚀开裂性的标准试验方法（等同采用ASTMG139-05(R2011)）（中文翻译版）编制: 日期:审核: 日期:批准: 日期:修订历史修订序号对应的条号修订内容修改人批准人日期1. 目的Purpose本标准试验方法涵盖了通过断裂荷载试验方法评估抗应力腐蚀开裂（SCC）性的程序，该方法使用剩余强度作为损伤演化（在这种情况下为环境辅助开裂）的测量方法。

包括试样类型和复制、试验环境、应力水平、暴露时间、最终强度测定和原始残余强度数据的统计分析。

2. 范围Scope本标准试验方法适用于热处理铝合金，即2XXX合金和7XXX，含1.2%至3.0%铜，且试样的取向与晶粒结构相关，横向较短。

然而，用于分析数据的残余强度测量和统计数据并非针对可热处理铝合金，可用于其他试样取向和不同类型的材料。

3. 职责Responsibility程序执行：实验室授权制样人员程序监督：实验室技术负责人及相关责任人4. 原理Principle4.1本试验方法描述了使用暴露于腐蚀环境后的残余强度评估热处理铝合金产品形式（如板材、板材、挤压件、锻件和棒材）的应力腐蚀开裂敏感性的程序。

这些产品通常在板材的长横方向、板材、挤压件和锻件的短横方向以及棒材和棒材的横方向上最易发生应力腐蚀开裂。

在本试验中，根据规程G49制备的拉伸钢筋或直接拉伸板试样暴露于3.5重量%的氯化钠水溶液（规程G44）中，在其失效前移除，并进行拉伸试验，以确定已发生的腐蚀损伤量。

然后计算平均剩余强度，并使用Box-Cox变换对结果进行统计分析。

4.2该程序要求暴露无应力试样，用于排除点蚀、晶间腐蚀和一般腐蚀的影响。

这些现象会降低残余强度，但不需要施加应力。

4.3本试验方法适用于高强度铝合金（2XXX和含有7XXX的铜），通常在3.5%氯化钠中通过交替浸泡进行试验。

然而，使用剩余强度作为损伤演化度量的概念（在这种情况下，环境辅助开裂）原则上可以应用于任何合金和环境系统。

弹性联轴器的技术参数

弹性联轴器的技术参数弹性联轴器的技术参数弹性联轴器通常由金属圆棒线切割而成，常用的材质有铝合金、不锈钢、工程塑料。

弹性联轴器运用平行或螺旋切槽系统来适应各种偏差和精确传递扭矩。

弹性联轴器通常具备良好的性能而且有价格上的优势，在很多步进、伺服系统实际应用中，弹性联轴器是首选的产品。

一体成型的设计使弹性联轴器实现了零间隙地传递扭矩和无须维护的优势。

弹性联轴器主要有以下两个基本的系列：螺旋槽型和平行槽型。

12高强涤纶绳相比于传统的绳索更加轻巧，具有较低的密度。

这一特点使得该绳绳体积小，重量轻，便于携带和使用。

同时，由于其密度相对较低，该绳具有较好的浮力，使其在水上活动中具有较强的漂浮性能，可以用于水上救援等场景。

此外，12高强涤纶绳还具有出色的耐久性。

其优质的材料和制造工艺使得该绳能够经受住长时间的使用和各种恶劣环境的考验，具有较长的使用寿命。

同时，它对紫外线、化学物质等外界环境因素具有一定的抵抗能力，减少了绳索受损的风险。

最后，我们也要关注涤纶绳的柔软性参数。

12高强涤纶绳采用柔软耐用的材料制成，具有良好的弯曲性能和抗扭转能力。

这使得绳索在使用过程中更加灵活，并且不容易打结、缠绕，提高了工作效率。

此外，12高强涤纶绳还经过特殊处理，使其表面光滑，降低了摩擦系数，减少了对周围物体的损伤。

综上所述，12高强涤纶绳具备优异的强度、密度、耐久性和柔软性参数，适用于各种领域的应用。

通过了解和掌握这些参数，我们可以更好地选择和使用涤纶绳，以满足不同场景下的需求。

139-型电子管接收机简介与维修图纸

139-型电子管接‎收机
八一型15‎瓦短波电台‎是我国第一‎代自研的制‎式电台，由天津电工‎二厂研制，抗美援朝时‎期装备部队‎，下发到师团‎级，反响不错。

后部队反映‎合体式的大‎八一过重不‎方便携带，厂家将收讯‎部独立出来‎，这就是13‎9型收讯机‎。

139接收‎机频率范围‎2~12 MHz，使用7只直‎热式电子管‎，甲电1.5 V，乙电90 V。

1969年‎的中苏珍宝‎岛冲突中，一名新战士‎使用139‎接收机抄到‎了失踪许久‎的巡逻队的‎微弱信号，避免了冲突‎扩大，战场立功连‎升三级。

电子管13‎9的后续型‎号是使用了‎锗晶体管的‎139A和‎锗管硅管混‎合的139‎B，体积、重量、功耗大幅度‎降低，但效果都没‎有电子管1‎39号。

由于电子管‎在抗核爆方‎面独到的性‎能，电子管13‎9并未立刻‎退出历史舞‎台，作为战备物‎资一直生产‎到70电台‎末。
