c902,h265编码格式

c902，h265编码格式？

1、H265一个图像序列的组成：VPS+SPS+PPS+SEI+一个I帧+若干个P帧。VPS、SPS、PPS、SEI、一个I帧、一个P帧都可以称

为一个NALU。

2、H265的NALU结构：开始码+NALU头+NALU数据

（1）、开始码大小为四个字节，是一个固定值00 00 00 01（十六进制），标识一个NALU的开始。

（2）、NALU头大小为两个字节，共16位，第1位值为0，第2-7位为NALU的type位（共6位），标识当前NALU的类型

，第8-15位值为0，第16位值为1。

（3）、NALU数据为编码器编出来的图像信息或图像数据。

3、六种类型的NALU

（1）、VPS（视频参数集）：NALU头值为0x40 01（十六进制），NALU头type位值为32（十进制）。

（2）、SPS（序列参数集）：NALU头值为0x42 01（十六进制），NALU头type位值为33（十进制）。

（3）、PPS（图像参数集）：NALU头值为0x44 01（十六进制），NALU头type位值为34（十进制）。

（4）、SEI（补充增强信息）：NALU头值为0x4e 01（十六进制），NALU头type位值为39（十进制）。

（5）、I帧：NALU头值为0x26 01（十六进制），NALU头type位值为19（十进制）。

（6）、P帧：NALU头值为0x02 01（十六进制），NALU头type位值为1（十进制）。

4、H265的NALU打包成RTP包的模式（下面是用到的两种模式）

（1）、一个NALU打包成一个RTP包，只需要在一个12字节的RTP包头后添加去掉开始码的NALU即可

（这种模式在一个NALU的大小小于MTU时使用）。

（2）、一个NALU打包成几个RTP包（FUs模式），在12个字节的RTP头后面有两个字节的PayloadHdr和一个字节的FU

header。PayloadHdr的值等于NALU头的type位改为49（十进制）后的值，FU header第1位标记RTP包是否为NALU的第一片，第2位标

记RTP包是否为NALU的最后一片。后6位是NALU头的type位。

如何学围棋？

围棋起源于中国，中国古代称为“弈”，距今已有4000多年的历史。围棋使用矩形格状棋盘及黑白二色圆形棋子进行对弈，棋子必须走在空格非禁着点的交叉点上，双方交替行棋，落子后不能移动或悔棋，以目数多者为胜。

围棋组成

棋盘

围棋盘是方形的，由纵横各19条线组成。19╳19形成了361个交叉点。上有九个星，最中间的称“天元”，“元”是第一的意思，“天元”意为天空最高点。

棋子

围棋的棋子分为黑白两色，黑子181枚，白子180枚，黑白子加起来是361枚，恰好和棋盘的点数相同。

围棋规则

对局双方各执一色棋子，空枰开局，黑先白后，交替着一子于棋盘的点上。棋子下定后，不再向其他点移动。轮流下子是双方的权利，但允许任何一方放弃下子权而使用虚着。

一个棋子在棋盘上，与它直线紧邻的空点是这个棋子的“气“”。直线紧邻的点上如果有同色棋子存在，这些棋子就相互连接成一个不可分割的整体。直线紧邻的点上如果有异色棋子存在，此处的气便不存在。棋子如失去所有的气，就不能在棋盘上存在。

把无气之子清理出棋盘的手段叫提子。提子有二种：下子后，对方棋子无气，应立即提取对方无气之子。下子后，双方棋子都呈无气状态，应立即提取对方无气之子。

棋盘上的任何一点,如某方下子后，该子立即呈无气状态，同时又不能提取对方的棋子。这个点叫做“禁着点”。

棋局下到双方一致确认着子完毕时，为终局。对局中有一方中途认输时，为终局。双方连续使用虚着，为终局。

终局时，经双方确认，不能被提取的棋都是活棋。终局时，经双方确认，能被提取的棋都是死棋。

围棋术语

围棋术语是在围棋中用来表达某些特定概念和词语的称谓，它囊括了围棋的专用名词、理论知识以及竞赛规则和对局经验的许多内容，既是中国围棋文化千百年来不断发展的产物，也是人们学习围棋应该掌握的基本常识。

基本概念

气

在棋盘上，棋子与它直线紧紧相邻的空交叉点，就是这个棋子的“气”。单独一个棋子的气数不超过四气，但两个或两个以上相连的棋子则可以有四气以上。棋子若失去所有的气，就成为死棋，不能在棋盘上存在。

目

棋盘上，被一方棋子所围地域的空交叉点，称之为“目”。一个交叉点即是1目，目的数量称为“目数”。

空

用棋子围成的地域。

地

（1）即地域或空。指已为某方占有的地区。

（2）形势判断用语。如“黑地六十目”，即指黑方可望在全局围有六十目的地域。

（3）指占有子和“空”的总和。即棋子围有的全部交叉点。

所包围的目数和活棋本身之总和，称为“地”。

提子

将对方无气的棋子从棋盘上取下，称为“提子”。

打劫

双方可以轮流提取对方棋子的情况。围棋规则规定，打劫时，被提取的一方不能直接提回，必须在其他地方找劫材使对方应一手之后方可提回。

真眼

由几个连接在一起的棋子围住一个或两个空交叉点，则称该点为真眼，简称“眼”。

假眼

由几个没有完全连接的棋子围成了眼的形状，称为“假眼” 。在一定条件下，围成假眼的棋子会被对方吃掉。

活棋

棋盘上凡是对方无法提取的棋即是活棋。活棋通常要具备两只真眼。

死棋

棋盘上迟早能被对方提取的棋，即为死棋。死棋不具有两只真眼。

双活

双方互围的棋子均无两只真眼，但又不能制杀对方时即为“双活”，也称“公活”。

禁着点

棋盘任一点，一方下子后，该棋子即呈无气状态，同时又不能提取对方的棋子，这个点就称为该方的“禁着点”。一方不能下子的禁着点，对方可以下子。

布局

布局是一盘棋的先导，也是双方进行阵容部署、各自抢占要点，为双方接触作战作准备的阶段。

定式

是指布局阶段双方在角部的争夺中，按照一定的行棋次序，选择比较合理的着法，最终形成双方大体安定、利益大体均等的棋本棋形。定式的种类有星定式、小目定式、三三定式、目外定式、高目定式等。

中盘

指双方在布局之后从短兵相接开始进行的全局性作战阶段。

收官

中盘作战基本结束，双方所占地域已经大致确定，进而使双方属地完全明确的一系列着法。

星

在棋盘坐标4·四的位置和棋盘正中央标有九个小圆点，术语称为“星”。这九颗星，将棋盘大致划分为左上角、右上角、左下角、右下角、上边、下边、左边、右边和中腹九个区域。

角

指棋盘四个角部星位内侧的区域。

边

指棋盘四个边星两侧的区域。

天元

棋盘正中央的一颗星称作“天元”。

小目

棋盘坐标3·四位置称作“小目”。

高目

棋盘坐标4·五的位置称作“高目”。

目外

棋盘坐标3·五的位置称作“目外”。

三三

棋盘坐标3·三的位置称为“三三”。

急所

指对局时，急需抢占的要点之处，无固定位置。

大场

指布局时，棋盘上下子后能够开拆或分投之处。

天王山

"天王山"一词是指在布局阶段，双方大势力的消涨要点，表示盘面中双方都应抢占的重要的位置。

俗称

挂

布局时在一方有一子占据角部时，另一方在其附近间隔一路或二路的位置行棋，称作“挂”。在三线行棋，称为低挂，在四线行棋，称为高挂。根据双方棋子的相对位置，又可分为一间高挂、二间高挂、一间低挂、二间低挂和小飞挂、大飞挂等。挂的目的在于破坏或侵占对方所占的角部。

缔

也称为“缔角”或“守角”。指在己方原有小目、高目或目外一子的基础上，再下一着棋，使己方两个子相互配合守角的着法。缔角既有利于围占角地，又可进一步控制和开拓边上的大场，是布局阶段常采用的着法。

长

双方棋子紧贴着向同一方向行棋，先行的一方，棋子会始终高出对方一头。长的着法能将己方的棋子连接成一个整体，这样可以延长棋子的气，既可以防止对方的攻击，又便于伺机攻击对方。

立

紧靠着己方原有的棋子，竖着向边线方向下一子的着法。通常多指在二线或三线的行棋。

尖

在原有棋子的斜线上下一子。由于尖的步子较小，也称其为“小尖”。在实战中，尖是一种攻守兼备的下法，既能够保持两子间的连络，又能够出头，控制行棋的方向。

飞

从原有棋子出发，向棋盘“日”字形的对角上下一子，叫小飞。若下在 “目”字形的对角上，就叫做大飞。飞还有一种形式，叫做象步飞。与象棋的象步走法相同。

压

在己方有子力配合的情况下，将棋下在对方棋子的上面，其主要作用是压制对方，扩张自己的外势、使己方的棋更加厚实，强大。压的着法往往还有声东击西的作用。

拆

从原有棋子的同一横线上，向左或向右有间隔地下一子。如果间隔一路，称为“拆一”，若是间隔二路，则称 “拆二”，其余类推。

挡

在双方棋子相互接触时，直接阻拦对方侵入己方地域或阻止对方被围的棋子向外冲出的着法。

碰

在无己方棋子接应时，紧靠着对方的棋子旁边下一子，称为碰。通常是用于试探对方怎样应对，追求变化的一种手段。

靠

在有己方棋子作策应的情况下，紧贴对方棋子旁边下一子。

搭

在己方棋子与对方棋子间隔一路的情况下，紧贴对方棋子的两侧下一子的着法。也称作“搭靠”。

接

将可能被对方分断的棋子连接成一体的着法。

粘

（zhān）指将被对方“打吃”的棋子与己方的其它棋子连接成一个整体的着法。

挖

在对方相隔一路的棋子中间下一子的着法。这种着法通常用在能够分断对方棋子，并能有效地攻击对方的场合下。

夹

将对方棋子夹在我方两子中间的着法。

滚

也称滚打。指由己方先弃一、二子，然后把敌子打吃成凝聚形状的着法过程。

打

也称打吃。在对方棋子只有两口气时，再下一子，使其仅剩一口气的状态。

双打

下一子同时打吃对方两边的棋子，形成两者必得其一的着法。

提

下一子，使对方的棋子立即呈现无气被吃状态，随即把被吃的死棋从棋盘上提取掉。

征

也称做“征子”，是围棋中吃棋子的一种方法，俗称“拐羊头”。被“征吃”一方的棋子因只有一口气，如若没有己方棋子接应，即使立即逃出，对方可按预定的行棋次序继续紧气追杀，最终会将其全部吃掉。

卡

（qiǎ）在对方棋形的要害处下一子，使其立即呈现某种缺陷的有效着法。

掖

紧挨着对方成“尖”形的两个子旁边下一子，具有约束对方棋形或使对方棋形出现断点或缺陷的着法。

曲

将棋背向对方的棋子走成弯曲的形状，称为“曲”。

玉柱

在角部或边上原有一子的基础上再下立一子的着法。用于加强己方的形势或稳固己方地域。

尖顶

紧靠对方的棋子下一子，在使己方棋子成“尖”形的同时，起到顶撞对方棋子的作用。

鼻顶

在对方棋形正前方顶住对方若干棋子的着法。

连

下一子，将两处分开的棋子若即若离地取得联络，以保证大块棋子安全的着法。连的常用着法有跳、关、拆、小飞、大飞、大跳等。

基本杀法

中局战略

对对方的弱棋，特别是失去很据与其已成活的棋子没有联络的孤棋进行攻击，是中盘战中争取主动的重要手段。

遇到对方出现孤棋，一定抓住机会进行攻击，争取吃掉对方以获取对局中的最大效率。这样往往会引起激烈的战斗，要经常审视围杀中自己出现的问题，否则非但歼敌不成反会断送自己。 在攻击中完全歼灭对方一片棋的情况是不多的，多是通过攻击获得其他好处，其中之一即是扩展自己的领地，巩固己之本来不稳固的领地，也通过攻孤棋来达到目的。 通过连续攻击压迫敌棋边角，也加强自己的外势，但要分析、计算好，在什么形势下有利,什么形势下不利。

从发展来看，治理孤棋首先考虑的是向中央出头。不能出头，被封住往往是吃亏的，除非逃不出时才行此下策。

当遇到攻击，无法向中央出头时，有机会、有条件时可以联络到自己另一块棋上去。

如出头和渡过均不可能时只得就地求活，如单独活不成，则争取双活，如果双活亦不成时，应停止这一带的活动，停止得越早越好。

缩小眼

从周围挤压对方的棋的生存空间，使它不能有做成两只真眼的空间。

点中心点

对方有一个中心点是做眼的要点，一旦被对手抢先，就能做出两个或两个以上的真眼。比如直三、弯三、刀把五、梅花六，这些棋形的中心点就是杀棋的要点。

打劫杀

在不能净杀的情况下，可以通过打劫来杀死对方，职业棋手往往擅长利用劫争一举获得优势。所以有时双方棋形的厚薄，劫材的多少，也是一盘棋的胜负关键，往往多一枚劫材就决定了大盘的胜负。

胀死牛

将对方点眼的棋子的外气全部紧完，在对方虎口里走一子，然后打吃对方，使对方不能连，将其胀死，称为“胀死牛”。

布局常识

布局指围棋的开局走法，一般在几手到几十手的范围内。局棋的进行一般由布局、中盘、官子三个阶段构成，布局作为一局棋的初始阶段，奠定了整个棋局的骨架与脉络。对局双方各自抢占棋盘上的空地，同时尽量阻止对方占地，由此导入中盘战斗。围棋有谚语“金龟银边莫肚皮”即以国突效率而言魚上最高、中腹最差。

围棋基本布局

三连星

即在边上星位连下三颗子，这一布局极易成大模样。对于另一方来说，必须有“钻地道"和"拆天桥”的能力，否则必败无疑。 由于三个子都处在第四线上，故这种布局的侧重点不是占角，而是向中央发展。三连星的用意在于取势或构成模样，中央是它的主要战场，这是三连星的特征。

二连星

较之三连星，二连星更为灵活多变，速度也快，并可视局部变化取地或取势，而不像三连星那样很容易就走上单一取势的道路。

中国流

它的外形与三连星相似，如果把它放平了看，有一种“桥”的感觉，因此在中国也叫做桥梁式布局。

相小目

黑1、3子占相邻的两个角，同以小目的四线一方指向白棋，称为“相小目”。其特点是把着眼点集中在一方。

星小目

黑1、3用星和小目占相邻两角，称为“星小目”

对战心态

修身养性，切忌浮躁

棋手实战时觉得局面都已占优，注意力不集中的情况下出现昏招，形势顿时翻盘。接下来绝大多数棋手会立即要求再来一盘以求“报仇”，但是接下来的对局心态已失去了平常心，于是连下连败以致一败涂地。

具备谋略心机

谋略是为创造有利条件而实行的全盘性行动的计划和策略，也就是创造致胜条件。这需要长期的对弈、总结、打谱的积累。

1、真正的进攻就要有收获，就要使局面朝着有利于自己的方向发展，这叫做攻有所获。

2、单纯的防守不好，具有反击的防守才真正具有威力，这叫做守中有攻。

3、在面对可能出现两种有利局面的时候，选择最大程度有利于自己取得胜利的局面。在面对可能出现两种不利局面的时候，选择最小程度不利于自己的局面。

4、寻找出进攻的机会和线路，熟练地运用各种技战术，使局面朝理想方向发展，这叫做捕捉战机。

5、中局作战过程中，要时常对当前局面有清醒地认识，该攻则攻 ，当守则守，进攻的线路，防守的要点，都在审局度势的范围之中。

6、多算胜，少算不胜。

902胶水和901区别？

一、901胶水：

配制方法：一公斤胶粉兑80-100公斤自来水，先用清洁的容器加入自来水进行搅拌，然后将胶粉徐徐加入，（不能一次或大量加入），加完胶粉后，继续搅拌，待胶粉完全溶解后，静置20分钟即可使用。长期未用在使用前，搅拌后即可使用。

该产品是由多种高分子聚合物、辅以功能助剂科学配制而成。

性能：用901胶水粉制成的胶水无毒、无污染、无气味、无放射性、无碱性、能速溶于冷水，不含粮食玉米定粉、烧碱。具有成膜快，粘度高、悬浮保湿、抗酶耐老化、用量小、保存时间长。性能稳定。用其配制的涂料，施工方便，不尿线、流平性好、不卷皮。是聚乙烯醇，丙烯酰胺胶水的理想替代的产品。

二、902胶水：

配方：A为聚酯树脂的乙酸乙酯溶液1，B为聚异氰酸酯的乙酸乙酯溶液2，C为银粉7。

性能：2天或者80℃/1.5h，80 ℃固化1.5h粘接强度Ly12铝板为10～120MPa，紫铜8～10MPa，20~C固化48h Ly12铝板为8～9MPa，紫铜8～10MPa;拉伸强度黄铜9～10MPa，电阻率(1～3)×10-3Q·cm

阿里刚发布的玄铁910芯片在国际上什么水准？

我来回答一下这个有关芯片的问题！

2019年7月25日，阿里旗下的半导体公司“平头哥”正式发布了玄铁910芯片，而之所以取名“玄铁”，是希望该芯片有如金庸笔下的“玄铁重剑”一样，重剑无锋、大巧不工。

不过与我们经常听到的英特尔公司的用在电脑上的芯片，还有华为、高通的用在手机上的芯片不一样，这次的“玄铁910”芯片是一种基于RISC-V指令集的处理器。

什么是RISC-V指令集？

所谓的指令集，做一种形象的比喻，就是一门语言，人类想要指挥芯片计算我们想要的结果需要通过“指令集”来翻译我们的命令，所以玄铁910就是一种只能够听得懂这门叫做“RISC-V”的语言的芯片。

而正是因为如此，所以我们暂时不会看到玄铁910用在电脑上和手机上，因为手机软件、电脑软件发出来的指令玄铁910根本就“听不懂”。

那么RISC-V指令集芯片可以用来干什么？

事实上，RISC-V指令集是一种相对来说非常“年轻”的指令集，直到2010年的时候，这种指令集才出现了比较早的雏形，相比较之下，Intel的x86指令集和ARM公司的ARM指令集已经算是“老家伙”了。

所以这种指令集一方面非常“年轻”，充满了活力，比那些老资格的指令集效率更高。比如说借用下图可以看到，在相同的工艺下，RISC-V指令集芯片更快、更小、功耗更低。

而另一方面，正是因为这种芯片太年轻了，所以“生态不好”，简单说就是可以用的软件太少、愿意为这种芯片开发软件的公司太少。

看起来，RISC-V指令集相比电脑上独占鳌头的x86指令集和在手机上独霸天下的ARM指令集，几乎是“白手起家”，但是不要忘了，软件生态都是可以“培养”起来的。

RISC-V芯片在物联网和5G上有着非常广泛的前景。

由于RISC-V芯片具有功耗低的优点，所以在一些对功耗、性能要求比较苛刻的使用场景，比如说物联网、自动驾驶和5G中，有着极大的优势。

而且现在的物联网还处于一片蓝海，涉及的企业很少，如果阿里巴巴可以抓住这个机会率先推出RISC-V芯片、培植相关产业的发展，可以说是前途无量。

而且本身阿里的玄铁910芯片就是一枚功能不俗的芯片，在性能上有着非常不错的表现（如上图所示）——这一方面是因为阿里进入这个领域进入得早，另一方面跟阿里本身的实力强。所以无论如何，阿里已经在目前的这个时间点，获得了先手优势。

总之，玄铁910芯片是阿里在新一代芯片布局中打下的一枚棋子，野心不小，希望他们可以顺利地在新一轮的科技发展中获得先机！
