#define怎么用
作者：tommylin
写在最前
好久没有装ITX了，这次给大家带来的是分形工艺Define 7 Nano的装机展示。Define 7 Nano作为Define 7系列最小的型号，整体外观上延续了Define 7的家族设计语言，线条简洁硬朗，作为ITX机箱，在尽量缩减体积的情况充分保证了硬件高度兼容性，可容纳306mm的显卡，并能安装25mm厚度的前置风扇，支持ATX电源，支持280水冷和最高167mm高度的风冷散热，无论是风冷方案还是风冷方案都游刃有余。
装机配置
CPU：INTEL i7-12700K
散热器：追风者 Phanteks Polar T6-120
主板：华硕 ROG STRIX B660I GAMING WIFI
内存：海盗船 铂金统治者DDR5 5600MHz 16*2
显卡：华硕 ATS RTX3060 O12G GAMING
SSD：XPG 翼龙 S70B PCIe4.0 M.2 1T
机箱：分形工艺 Define 7 Nano
电源：九州风神 DQ850M-V3L 金牌全模组电源
整机展示
特别喜欢Define 7 Nano正面的这一整块全铝拉丝面板，没有任何多余的修饰，质感满满。
依旧选择NO RBG，只留下和模组线同色的内存微光灯效。
俯视LOOK，顶部也十分清爽，由于散热压力不大，所以没有选用通风顶盖。
打开侧面的侧头面板，更好的展现内部硬件。可以看到机箱前段上方的空间还是很富裕的。
能装下标准双塔散热，风冷方案就达成了。
追风者的Polar T6-120整体效能不错，压制12700k，IA超频模式下稳稳的。
无光的巨齿鲨3060，尺寸、性能都是那么的刚刚好。
依旧出色的海盗船铂金统治者，5600 16G*2，微光下隐藏着暴虐的性能。
由于安装了高马甲内存，所以我将散热器原本挂载在前端的风扇移到了后端，机箱本身尾部的风扇则安装到了机箱前部，加大进风效果。
前面板唯一的装饰，暗纹LOGO角标。
整机安装
由于只使用了风冷且没有过多的风扇，平台安装就比较轻松了，装上散热，插上显卡和内存，完活。
ITX就是这么小巧可爱，整体平台大小和电源差不多。
由于使用了高马甲内存，我将本来挂载在前端的散热风扇安装在了散热器后方，将机箱自带的尾部风扇安装到了前面。
背部，理线很轻松，干干净净，清清爽爽。
装机配件
核心配置用12700K搭配B660-i，没有Z690i的采用叠叠乐设计，大大的提高了散热器的兼容性，采用8+1供电模组，搭配ProCool高强度电源接口, 高品质电感及耐久电容为多核处理器提供高效稳定的供电效率，8层PCB设计，另一个M.2的安装位位于主板背面。
一体式I/O+VRM散热装甲，斜切式的散热格纹设计和M.2散热片上的铭牌保持一致性，整体看上去还是很有科技感的，主板的右侧，双内存插槽设计，支持DDR5，双通道内存架构，Max. 64GB, DDR5 6200(超频)，支持 Intel Extreme Memory Profile (XMP) 技术。右侧依次为：系统面板接针，24-pin 主电源插座，USB 3.2 Gen 2 连接端口，USB 3.2 Gen 1 连接端口，4个SATA 6Gb/s 接口。
IO面板接口，1 x USB 3.2 Gen 2x2 接口 (1 x USB Type-C)，4 x USB 3.2 Gen 1 接口 (3 x Type-A +1 x USB Type-C)，3 x USB 2.0 接口 (3 x Type-A)，1 x HDMI 接口，1 x DisplayPort，1 x Wi-Fi 模块，1 x Intel I225-V 2.5Gb 网口，5 x 音频插孔。
内存选择海盗船铂金统治者DDR5 5600MHz 16*2套条，外观依旧经典，性能依旧卓越，5600MHz的频率，时序为CL36-36-36-76，32G的容量足以应付日常90%以上的应用。
海盗船家族式的超高散热马甲设计，采用DHX散热技术，三段式的梳子造型，顶部12颗CAPELLIX RGB LED灯珠，搭配自家的ICUE软件，灯效直接拉满。
SSD采用XPG的S70 BLADE，PCIe4.0，M.2规格，除了SSD本体，还附赠了散热马甲片，可进一步提高散热性能。
主控来自InnoGrit IG5236CAA，采用了12nm的制程工艺，拥有8个NAND通道，最大支持16TB，边上的为三星K4A4G16缓存芯片，再边上则是威刚的自封装颗粒。
显卡则是使用了非常适合ITX装机的ATS-RTX3060-O12G-GAMING，双风扇设计，体积紧凑，体积为268 x 136 x 53mm。整体黑色涂装，在导流外壳上有尖锐不规则几何图形点缀，表面渐变显示很具科技感。
虽然是入门显卡，但是依然带有铝合金背板，这个必须是好评的，铝合金背板为电路板带来强有力的保护，提升了结构强度，有助于防止扭曲并保护组件与
为了消除不必要的噪音，ATS-RTX3060-O12G-GAMING采用风扇智能停转模式，当显卡温度低于 55C 或功耗较低时，风扇可自动停止运转。双滚珠轴承风扇，轴流风扇设计，两个可靠的轴流风扇具备较小的风扇轮毂以使用更长的扇叶，环形密封环可提高向下风压。
显卡侧面带有NVIDIA的GEFORCE RTX和ASUS LOGO，无灯效，这个其实更得我心意，全卡无光就对了，QTMDRGB！透过中间的空隙可以看到硕大的镀镍散热片。同时不到2.5槽的厚度对于小机箱是特别友好的。
显卡的辅助供电部分，为单8Pin，辅助供电插座旁边为BIOS切换开关，支持P、Q两种模式切换
硕大的散热片，三热管设计，一体式铜底，这个规格的散热对3060来说可谓游刃有余了。
在输出接口方面，ATS-RTX3060-O12G-GAMING提供了2HDMI+3DP。
散热方面选择了风冷，追风者新推出的Poar T6-120，根据官方介绍，是追风者联合华南理工大学利用教授半导体热管理科研团队共同研发。风扇双排塔结构，采用了6根铜质热管，密集的双塔式散热鳍片阵列搭配两个M25无光风扇，散热器的整体尺寸为125.2*137.4*155mm，最大散热功率可达280W。
Poar T6-120配件一览，扣具支持最新的INTEL 13代和AMD ZEN4，针对新一代CPU发热源及承重磅力针对性优化，背板为金属材质，自带高性能碳纳米导热硅脂并附带了刮板。
Poar T6 120鳍片组是穿FIN的工艺，出于成本控制，鳍片均为进行镀镍。
Poar T6-120的顶部附带了庄市顶戴，采用磨砂处理，并带有Phanteks的logo字样，提升了散热器的整体质感。
Poar T6-120采用镀镍复合型热管，6根管分别进行了参数调教，已达到塔体和热源及应用场景重力方向的合理匹配，在机箱直立式，散热性能不受重力影响。
Poar T6-120底座为纯铜材质，CD纹镜面高光工艺，铜底微凸，更好的贴合CPU。
自带两枚12cm的M25风扇，转速为400-2000 rpm，风扇带PWM温控4Pin串联短接线。
兼容性方面，由于采取塔体避让和VRM避位设计，支持67mm的高内存，对有厚重VRM的主板也很友好。
电源选择了九州风神的DQ850-M-V3L，通过了80Plus金牌认证，作为DQ850-M-V2L的升级型号，长度从16cm缩短至14cm，进一步完善了兼容性。正面风扇格栅与顶盖一体化设计，上下两边的棱边做了圆弧化处理，表面整体磨砂材质。采用直径为120mm的FDB液态动压轴承风扇进行散热，支持智能启停功能，低负载时可实现零噪音运行的效果。
九州风神DQ850M-V3L采用主动式PFC + 全桥LLC谐振 + 同步整流 + DC-DC设计，额定功率为850W，支持100V到240V交流输入，+12V为单路输出设计，额定输出电流为70.8A，相当于849.6W功率；+5V与+3.3V则通过DC to DC从+12V转出，每路输出均为最高20A，联合输出功率额定为100W。
AC输入接口带有独立开关，但没有设立智能启停功能按钮，电源开关也是和logo同色。侧面带有内嵌设计的九州风神logo。
九州风神DQ850M-V3L采用全模组设计，模组线材均为黑色扁平线材，提供有1个24pin主供电接口、1个4+4pin CPU供电接口、1个8pin CPU供电接口、3个6+2pin PCI-E供电接口、8个SATA供电接口和4个D型4pin供电接口。
Define 7 Nano整体造型方正简洁，体积为399 x 205 x 361 mm。铝板拉丝的前面板和侧板顶部推扣的巧妙设计，呈现出精致且十足的质感。
Define 7 Nano前面板打开后可以看默认附带的1个Dynamic X2 GP-14风扇，前部风扇支架支持2个120/140 mm规格风扇或240/280冷排的安装，面板內忖采用了工业级的隔音材料。
Define 7 Nano的进风口位于前面板两侧，长条形的百叶窗的设计并做了防尘处理。
Define 7 Nano两侧盖板，一侧为有色玻璃面板，上下有框架加固，另一次则为工业隔音钢板，侧板內忖同样采用了工业级的隔音材料。
机箱的I/O接口位于机箱顶部，左起分别为重启按键、音频麦克风输出接口、Type-c接口、开机启动按钮、2个USB2.0、2个Gen2 USB3.1接口。
Define 7 Nano顶部面板默认为封闭顶盖，同时附赠可一块通风顶盖，可以轻松拆卸替换，从而获得更高的散热效能。
顶部自带高气流尼龙防尘网，可拆卸设计更易于清洁。卸除防尘网后可以看到底部风扇安装支架，支2个120 或1个140薄款风扇 （厚度不超过15 mm）。
顶部的风扇安装支架是支持可拆卸的，在安装硬件和走线的时候更加轻松。
Define 7 Nano的底部大面积开孔设计，同样带有可拆卸的防尘网。

于爸风4763如何使用#define定义变量 -
边行的19617556696 ______ #define M 10 宏定义 ,M相当于10 你可以 const int m=10;
于爸风4763C语言#define是什么? 怎么用? -
边行的19617556696 ______ define ,中文名 就是 :“定义”,俗称 取名字.比如 给圆周率(3.1415) 取个名字 叫 Pai,给 单片机 P1 端口 取名叫 LED 等 #define Pai 3.1415 #define LED P1
于爸风4763我是c++初学者,想问一下#define要怎么用的,只要定义就好
边行的19617556696 ______ 理论上是定义宏的~ 但也可以看成是定义常量 至于他的有效域 是全局还是局部的看 定义它所在的范围 如果只是在一个函数体内定义 那么他只能作为一个局部常量来使用~~
于爸风4763c语言 define 怎么用的 -
边行的19617556696 ______ 宏定义 define 可定义常量如define pi 3.14;也可以宏定义函数如 #define MAX(x, y) ((x)>(y)?(x):y()这样比函数定义要好 可以减少堆栈的使用,并且这样定义可以比较多种数据类型,float int,相当于c++里面的模版了..而若是函数就只能比较一种.其实define一般不用来定义常量 以后你学C++就知道定义常量一般用const
于爸风4763C语言当中的预处理#define -
边行的19617556696 ______ 意思是用 IS_GPIO_ALL_PERIPH(PERIPH) 代替 (((PERIPH) == GPIOA) || ((PERIPH) == GPIOB) ||((PERIPH) == GPIOC) || ((PERIPH) == GPIOD) || ((PERIPH) == GPIOE) || ((PERIPH) == GPIOF) || ((PERIPH) == GPIOG)) 到程序中...
于爸风4763如何#define一个指针? -
边行的19617556696 ______ 可以用#define定义一个“指针宏”,不过这样的宏可能会引起程序错误,例如: #define X int * 这样定义了一个宏X,等价于int *,然后可能在后面的程序中出现以下两种形式的调用 : <1> X a; <2> X a,b; 对于第一种形式而言,是可以的,...
于爸风4763C语言中为什么和什么时候用#define -
边行的19617556696 ______ #define 的存在解决了许多程序敲代码的问题,也解决了其他人对程序阅读的障碍,比较能清晰明确的表达编程者的意图(当然如果你不想让别人看懂除外),而且不至于晕头转向. #define a b,的意思,是编译器检索你所有的程序,在#...
于爸风4763typedef和#define的基本用法
边行的19617556696 ______ C语言中,内置类型,如int型,其指针(int*)可以看成种新的类型,借助typedef,能容易地将函数指针类型化. 举列说明: typedef double* DP; DP pDouble1, pDouble2; 与 #define DP double* DP pDouble1, pDouble2; 通俗地说,#define是种字面替换,而typedef却是引入一个新的助记符号
于爸风4763#define 是干什么的?
边行的19617556696 ______ 有的时候为了程序的通用性,可以使用#define预处理宏定义命令,它的具体作用,就是方便程序段的定义和修改. 举个例子吧,如果说你在做一个项目,这个项目的代码很长,有5000多行,而且基本上里面的同一个常量N就占了3000多行,如...
于爸风4763请教一个#define语句的的含义,定义的结果是什么?以及一般如何使用? -
边行的19617556696 ______ 比如你在代码中写 PO_DEFINE_INTERFACE_UUID(abcde, 12345) 那么经过编译预处理后就会变成:static const pom::PoUUID abcde_IID = 12345;
