1. t959，316不锈钢有几种材质？

一般是201 202 304 316 这些 202和304用的较多 316和317不锈钢（317不锈钢的性能见后）是含钼不锈钢种。317不锈钢中的钼含量略高明于316不锈钢.由于钢中钼，该钢种总的性能优于310和304不锈钢，高温条件下，当硫酸的浓度低于15％和高于85％时，316不锈钢具有广泛的用途。

316不锈钢还具有良好的而氯化物侵蚀的性能，所以通常用于海洋环境。 316L不锈钢的最大碳含量0.03,可用于焊接后不能进行退火和需要最大耐腐蚀性的用途中 耐腐蚀性 耐腐蚀性能优于304不锈钢，在浆和造纸的生产过程中具有良好的耐腐蚀的性能。而且316不锈钢还耐海洋和侵蚀性工业大气的侵蚀。 耐热性 在1600度以下的间断使用和在1700度以下的连续使用中，316不锈钢具有好的耐氧化性能。在800-1575度的范围内，最好不要连续作用316不锈钢，但在该温度范围以外连续使用316不锈钢时，该不锈钢具有良好的耐热性。316L不锈钢的耐碳化物析出的性能比316不锈钢更好，可用上述温度范围。 热处理 在1850-2050度的温度范围内进行退火，然后迅速退火，然后迅速冷却。316不锈钢不能过热处理进行硬化。 焊接 316不锈钢具有良好的焊接性能。可采用所有标准的焊接方法进行焊接。焊接时可根据用途，分别采用316Cb、316L或309Cb不锈钢填料棒或焊条进行焊接。为获得最佳的耐腐蚀性能，316不锈钢钢的焊接断面需要进行焊后退火处理。如果使用316L不锈钢，不需要进行焊后退火处理。

（奥氏体不锈钢）主要有： 321 ，( 1Cr18Ni9Ti ) 又称18-8 304 ，( 0Cr18Ni9 ) 304L , ( 00Cr19Ni10 ) 306 , ( 0Cr17Ni12Mo2 ) 316L , ( 00Cr17Ni14Mo2 ) Mo2Ti。 主要区别：321含钛 316含钼 304既不含钛也不含钼 Mo2Ti既含钼又含钛 性能316L最优，321/304一般

2. 世界上第1辆汽车是如何获得机械能的？

德国人卡尔·本茨1885年成功研制出的世界上第一辆内燃机汽车。在这之前，车辆的动力由蒸汽机提供，这就需要车辆载着锅炉和煤炭劈柴，火车可以，公路蒸汽机车辆很难普及。

本茨1844年11月25日生于德国巴登-符腾堡的卡尔斯鲁厄，在他两岁时，开火车的父亲去世。尽管家境贫寒，本茨的母亲还是设法让他受到良好教育。本茨19岁时毕业于卡尔斯鲁厄大学机械工程专业。毕业后，本茨在几家公司频繁跳槽，均没找到如意的工作。

1871年，本茨与奥古斯特·里特尔合伙开办了一家机械制造厂。由于合伙人不可靠，生意很糟糕。本茨的未婚妻贝莎（1849—1944）便用自己的嫁妆钱买下了里特尔的股份。1872年7月20日，贝莎与本茨结婚，婚后生下5个孩子。

1878年12月31日，本茨成功研制出了两冲程发动机，并在1879年获得该项发明专利。在这之后，本茨又获得了变速器、火花塞、化油器、换挡系统和水散热器等与汽车相关的专利。

1882年，本茨的公司因债务问题重组，本茨的股份还剩下5%，他在公司失去了决策权，便于1883年转让了股份退出公司，与另外两人合伙成立了本茨内燃机公司。本茨开始研究把内燃机装在马车上替代马匹，这就是汽车的最初设计理念。1885年，本茨成功研制出了三轮汽车，并用他自己的姓“Benz”为世界上第一辆汽车命名。“奔驰”这个响亮的汉语名字是Benz汽车进入中国市场时起的。

本茨于1886年1月29日申请了汽车发明专利，并在1886年11月2日获得批准，专利号是DRP-37435。由于专利生效期是从申请之日算起，这样，1886年1月29日就成了汽车发明日。

“奔驰”专利汽车前面有一个轮子，后面有两个轮子，钢管车架，链条传动，水冷，汽油燃料，电火花四冲程卧式气缸，气缸直径116毫米，单缸，活塞冲程160毫米，排量959立方厘米，功率0.8马力，时速16公里。

奔驰公司生产的汽车从1888年夏天开始上市，成为世界上第一家汽车制造商。当时每辆奔驰汽车售价600帝国马克，相当于2017年的4000美元。

贝莎对丈夫的事业给予全力支持。1888年8月5日，39岁的她独自驾“奔驰3型”汽车带着13岁和15岁的两个儿子，从曼海姆到普福尔茨海姆看望母亲，单程106公里。贝莎创造了一个奇迹，因为当时还从未有人单程行驶这么远。贝莎这一勇敢的“自驾游”着实给奔驰公司做了广告。从此，汽车逐步普及开来，促进了石油开采和精炼业的发展。

1895年，奔驰公司还制造了世界上第一辆公共汽车。

到1899年，奔驰汽车公司已有430名员工，这一年生产了572辆汽车，是世界上最大的汽车制造公司。

1929年4月4日，“汽车之父”卡尔·本茨在自己家中去世，享年85岁。

3. 9593s轮胎是什么意思？

9593s是两个轮胎参数。95表示轮胎载重指数，此指数所对应的载重能力为 690公斤；93载重660公斤。即载重量在660至690公斤之间。s表示速度级别，最高速度不得超过每小时180公里。

轮胎是在各种车辆或机械上装配的接地滚动的圆环形弹性橡胶制品。通常安装在金属轮辋上，能支承车身，缓冲外界冲击，实现与路面的接触并保证车辆的行驶性能。轮胎常在复杂和苛刻的条件下使用，它在行驶时承受着各种变形、负荷、力以及高低温作用，因此必须具有较高的承载性能、牵引性能、缓冲性能。同时，还要求具备高耐磨性和耐屈挠性，以及低的滚动阻力与生热性。

4. PR教程？

Adobe Premiere是Adobe家族的一款剪辑软件，它给我的感觉就是入门快、功能强大，无论是对于新手还是专业人士，Pr在大部分情况下都是很友好的。

认识pr

Pr全称Adobe Premiere，是Adobe公司开发的一款视频剪辑&编辑软件。主要用于视频采集、视频剪辑、调色、添加字幕、编辑音频、渲染输出。

Premiere提供了采集、剪辑、调色、美化音频、字幕添加、输出、DVD刻录的一整套流程，并和其他Adobe软件高效集成，使用户足以完成在编辑、制作、工作流上遇到的所有挑战，满足用户创建高质量作品的要求。

下载PR软件

Adobe官网下载

进入Adobe官网进行下载https://www.adobe.com/cn/products/premiere.html

其他网页下载

1、打开浏览器今日头条搜索3D溜溜网，进入官网

2、打开浏览器百度搜索3D溜溜网，进入官网，点击上面【···】三个点之后选择【软件插件】里的【羽兔网软件下载】

3、选择【常用软件】里的【视频制作】

4、向下滑，在下面找到PR2018版本的进行【软件下载】，里面还有其他版本，这里选择的是适配win7的。

PR窗口介绍

Premiere软件由菜单栏、常用工具栏、时间轴、侧边面板栏（组件窗口）组成。主工作区有素材（项目）管理窗口、素材预览窗口、视频监视器窗口、时间轴窗口、调音台窗口、调色窗口等。

菜单栏

菜单栏可以说是整个软件的功能导图，为软件中大多数功能提供了菜单入口，例如PR软件中的绝大多数功能在对应的菜单栏中都可以找到。

功能窗口切换区域:(组件、编辑、颜色、效果、音频、字幕、库......)

功能窗口切换区域是软件为剪辑、调色、音频、字幕等不同功能定义的界面布局方案。点击对应的功能，软件会自动切换到使用该功能时的界面布局。

源素材预览窗口

源窗口主要是为项目面板中素材(视频、音频、图片)提供实时预览，双击项目面板中的素材即可在源窗口中进行播放预览。

节目监视窗口

节目窗口主要用于监视时间线上剪辑的画面，可以实时播放。

项目面板

项目面板主要是用于项目及素材的管理，我们导入到软件中的素材及新建的序列、字幕等素材全部都存放在项目面板中。

时间线窗口

时间线窗口可以简单理解为剪辑工作台，我们对素材的剪辑工作全部都是在时间线面板中操作完成。时间线窗口又可分为视频轨道和音频轨道。

工具栏

工具栏集合了所有视频剪辑工具，当然有一些是辅助剪辑工具。

选择工具（快捷键：V）

顾名思义，它的作用就是用来选择东西的，不过在有的时候它也会变为其它的形状，作用也随之改变。

向前选择轨道工具（快捷键：A）

使用此工具可以选择该轨道上以后的所有素材，视音频链接在一起的则音频同时也被选中；按住Shift键可以变为多轨道选择工具，此时单头变为双头，即使是单独的声音（比如音效、音乐等）也会被同时选中。

波纹编辑工具（快捷键：B）

使用此工具可以改变一段素材的入点和出点，这段素材后面的会自动吸附上去，总长度发生改变。

剃刀工具（快捷键：C）

pr中导入素材之后，利用剃刀工具切割开视频，视频就分开为多段了，可以分别剪辑切割后的每一段视频，包括删除、添加效果等。

外滑工具（快捷键：U）

作用于一段素材，用来同时改变此段素材的入点和出点。

钢笔工具（快捷键：P）

这个工具和字幕中的钢笔工具是一样，主要用来绘制形状。选中此工具，在需要的位置点击一下确定起点，直接点其它位置可以绘制直线，而在点第二个点的同时按住鼠标不放并进行拖拽可以绘制曲线；它还有一个作用就是进行关键帧的选择。

手形工具（快捷键：H）

点击鼠标左键，在时间轴上拖动，移动时间轴上显示素材的位置。当程序监视器放大时。拖放程序监视器中的可移动显示区域以观察细节。

文字工具（快捷键：T）

文字工具即在画面中输入我们想要的文字。

效果面板

效果面板集合了很多视频和音频效果控件，对视频或者音频添加模糊及转场等效果时，需要在效果面板中找到对应的效果控件然后添加到时间线上的剪辑。

效果控件面板

效果控件面板是对已经添加到素材上的效果进行参数调节的窗口。

音轨混合器窗口

对音频进行声道和音量调节的窗口，当然也可以通过这个窗口进行现场录音。

PR剪辑教程

创建项目

首先新建项目，暂存盘里的地址栏跟项目一样就可以。

新建序列

新建序列，选择1080P25，点击确定，就建立了一个时间线。

一般的剪辑软件里边都有现成的预设，只要知道这个尺寸就行，高清格式选择1080P或者720P都行。

导入素材

在项目列表双击，找到我们的素材，按住shift一块儿导入，导入之后可以对素材进行分类，让我们可以看的更仔细一些。（养成一个好的分类习惯，有助于提高我们工程的有趣性和效率，以后打包工程的整理都非常的有好处）。

拖入时间线

素材分类好之后，把视频音频素材按住shift一起都拖拽到时间线里。

设置比例

发现视频素材的大小不一，我们调整视频整体比例大小。找到信息，看见比例为640*360，在我们新建的时候不是这个比例，我们在序列里进行更改设置为640*360，这样时间线就跟我们相匹配了。

编辑视频

导入素材之后，我们开始对视频进行剪辑。

添加效果

添加效果，让视频看起来更流畅。

添加字幕

添加结尾字幕。

导出

剪辑完成，导出成品。

PR导出格式一般用MOV、mp4、AVI等等。PR输出视频的时候，要求不一样，输出的格式的就不一样。因为没有统一的标准，要根据需求和目的才能定什么是合适的。

1、如果想输出文件后继续进行编辑，一般推荐输出MOV。

2、如果输出文件后直接就要观看，或传到视频网站。推荐输出H.264，即mp4。

3、如果输出文件给电视台标清播出，就输出AVI格式。

成品

下面这张是成品

这里用的是PR2018版本

PR基础快捷键

1、按i可以设置入点，O可以设置出点。

2、Shift+delete键可以删除视频同时，把视频之间的间隙去掉；Ctrl+Z撤销。

3、向前选择轨道工具（A）和链接选择项的结合使用可以删除选择点后面的视频和音频

4、向前选择轨道工具（A）和取消链接选择项的结合使用按shift键可单独删除视频，保留音频。

5、按Q键可删除剪辑的开始，按W键可删除剪辑的结尾，但是它们会从每个音轨中删除内容，如果有多层音轨，这个快捷键就不适用，可以通过锁定音频轨道来避免音频被删除。

6、按光标键→，按一下前进一帧，按Shift键+光标键，一下会前进5帧。

7、alt+拖动素材=复制

常用的快捷键如下：

注：如果自己不适应默认的快捷键可以在PR界面快捷键设置修改，步骤如下：

打开快捷键界面有两种方法：第一种方法，打开PR后，在菜单栏找到编辑选项下的快捷键菜单，单击后就会弹出设置界面。第二种方法，打开PR后，我们直接使用快捷键Ctrl+Alt+K后，也会弹出设置界面。

打开快捷键界面后在搜索框里我们直接输入想要添加的快捷键功能，然后在空白处单击鼠标，就会产生一个框，按下要设置的快捷键，最后点击确定保存设置，这样就快捷键就设置好了。

PR视频特效

添加滤镜

首先就是滤镜的位置是在左下角的【效果】选项里面，如下图箭头指向所示：

里面的滤镜很多，可以选择自己喜欢的滤镜进行使用，如下图箭头指向所示：

然后，我们直接将滤镜拖拽到素材身上就可以进行使用了，如下图箭头指向所示：

调整滤镜的内部可调节参数，素材的效果就能实时预览。点击前面的【FX】可以进行滤镜效果的开启以及关闭，如下图箭头指向所示：

效果里面，除了视频滤镜，还有音频滤镜以及各种转场可用，如下图箭头指向所示：

添加字幕

在工具栏，点击文字工具；

使用文字工具点击视频，在文字框中输入字幕，就添加字幕成功了。

视频的删减

导入完素材之后我们将素材拖到右边，便能对视频素材进行编辑了（点击播放按钮可预览）。接下来我们讲一下视频内容的删减。

比如说：我们觉得某一段内容不好，想把它删掉，那么该怎么办呢？在PR中我们有两种方法：

1、选择左侧工具栏的刻刀工具，在想要删去内容的两头进行点击，然后即可将商品分割成三段，可从中选择自己不想要的内容；

2、直接从末尾拖动即可（只能对开头或末尾内容进行删减）。

视频的倍速播放

视频的倍速播放在PR中很容易就能实现了：右键-速度/持续时间。选择速度（百分比，如200%就是两倍速） ，点击【倒放速度】就能倒放了。

音乐淡出效果

添加音乐的方法和添加视频的方法一样，导入以后拖动到右边就可以了。删减运用上述方法也是可以完成的。

音乐淡出的效果：

添加完音频后，拉开轨道，点击左下的小按钮，选择：轨道关键帧-音量；

选择：添加-移除关键帧按钮，在想要淡入、淡出的地方添加关键帧，即可对音量进行修改，完成淡入、淡出的效果；

如果你是第一次使用PR并且佩戴耳机的话，要到PR的【编辑】-【首选项】-【音频硬件】里的【默认输出】修改输出设备为：耳机。

音效增益

打开PR软件，将音频导入进去，拖到右下方的【时间轴】操作区；

右击鼠标，点击音轨，在出现的选项中点击【音频增益】；

在【音频增益】页面，选择【将增益设置为】；

输入合适的音频值，负数表示减少，完成后点击【确定】。

视频转场

首先打开电脑上的PR，打开项目文件后，选择右侧的【效果】面板，效果面板中有音频效果、音频过渡，视频效果、视频过渡；

鼠标点开【视频过渡】，其中有7类转场特效，我们这里点击进入【溶解】，选择【溶解】下的【交叉溶解】；

选择【交叉溶解】拖动到视频上，可以看到我们可以将转场放置到视频末尾，视频开头或两段视频中间，这里选择【视频中间】；

插入完成后我们双击此转场，进入【设置过渡持续时间】，拖动蓝色字体即可增加或减少时间。

7. 安全阀有效期？

根据标准规定，安全阀需要下线进行一年一校验。有的工位比较特殊无法按时校验，所以通过在线校验来缓冲一下。在线校验只能是暂时的，不可以一直使用。按照规定，每次在线校验后，再次在线校验时间应该是上次校验时间的一半。

举例：安全阀使用一年了，在线校验有限期应该是6个月，再次校验后，有效期变为3个月，以此类推。
