国防科技大学“九章算术社”数学研究俱乐部成立于2024年11月，由理学院主责抓建。俱乐部logo巧妙融合了“9”和“Z”字母，是“九章”的创意演绎，赋予了数学的抽象美感。鲜红的图形象征着数学的热情与活力，三角形与圆的碰撞代表了数学的严谨与灵活，像一双洞悉真理的眼睛，又似一轮初升的朝阳，在数学的世界里，我们既是探索者，也是发现者。
主题曲《九章》将深邃的数学思想与豪迈的军事气概相融合，以《九章算术》为源，借数学语言抒写现代国防科技中的智慧与力量，旋律中既有演兵场上的铿锵节奏，亦有理数星河中的浩瀚意象。传递出俱乐部成员以数明理、以算为战、以智取胜的坚定信仰与创造精神，彰显出他们善于推演、敢于创新、忠于使命的昂扬面貌。
《九章》歌词
九章遗韵，智慧漫卷于竹简
The legacy of Nine Chapters, wisdom unrolls on the bamboo scrolls
数海探秘，似见星河耀穹苍
Exploring mysteries in the sea of math, as if witnessing starry rivers illuminating the sky
密码迷局，数学密钥破玄障
Cipher enigmas, mathematical keys break through mystical barriers
计算狂潮，烽烟疆场卷巨浪
A tidal wave of computation, sweeping giant waves across the beacon-lit battlefields
看，九章薪火映千年星光
Behold, the torch of Nine Chapters illuminates a millennium of starlight
运筹帷幄中，决胜千里写穹苍
Planning strategies within, deciding victories a thousand miles away, carving our saga across the heavens
众志同航，数海深处探微芒
With one will we sail, probing faint lights deep in the math sea
思维作翼，穿云破雾千重嶂
Thought as our wings, piercing clouds, breaking through fog and countless peaks
算筹为笔，演兵场上定攻防
Counting rods as our pens, on the training ground determining attack and defense
九章遗韵，奋进一流于湘江上
The legacy of Nine Chapters, we strive to build a world-class institution along the Xiang River
以数启思，明理求实心自昂
Mathematics sparks the mind, understanding truth, seeking facts, our spirits soar
携手同行，探索之路共丈量
Walking together hand in hand, measuring the path of exploration as one
数字铿锵，盾守山河铸利剑
Numbers ring like steel, shielding mountains and rivers, forging a sharp sword
逻辑锋芒，科技强军绽荣光
Logic's sharp edge, tech-empowered force lets glory blaze
爱数者笃，学数者明，用数者勇
Those who love math are steadfast, those who learn it are enlightened, those who use it are brave
路漫漫修远，吾辈上下求索长
The road ahead will be long and our climb will be steep
为战而研，寸寸公式皆沙场
Research for combat, every inch of formula is a battleground
为战育人，迷彩阵深藏数理
Educate for combat, camouflage arrays deeply conceal math and science
定理为戈，证明所向皆无惘
Theorems are our spears, our proofs leave no doubt
初心如磐，我辈自可算定四方
Our initial resolve steadfast as rock, our generation can calculate to secure our land
当算筹在竹简划过第一道微光
When the counting rod first etched a faint gleam across the bamboo slip
刘徽执径寸丈量天地的宽广
Liu Hui held his calipers, measuring heaven and earth's vastness
方圆之术 刻出微积分的徽章
The art of circle and square engraved the very emblem of calculus
商功用堑堵堆垒三维的山岗
Shang Gong used trenches and embankments to stack 3D hills
开方术破土 抽枝少广章
The root-extraction method broke ground, branching forth in the Lesser Breadth chapter
粟米章比率 织就在粮仓
Ratios from the Millet and Rice chapter, woven through the granary
勾三股四 弦系星汉长
Three, four, five, the hypotenuse ties to the long Milky Way
正负相抵谱写二进制文化的光芒
Positive and negative cancel out, scripting the light of binary culture
千年后的算筹化作二进制的涟漪
Millennia later, counting rods became ripples of binary
减损术裂变递归成算法的军旗
The method of subtraction and addition fissioned, recursed into algorithmic banners
排布化作迷彩暗藏异或玄机
Arrangements become camouflage, hiding XOR mysteries
处理器上矩阵战梯在侵袭
On processors, matrix battle ladders invade
Σ求和似星河归位
Σ summation is like the starry river falling into place
聚合出防御的光
It converges into a light of defense
ε筑起极限的壁垒
ε builds the barrier of limits
抵挡下精密的枪
Withstanding the precise shot
众志同航，数海深处探微芒
With one will we sail, probing faint lights deep in the math sea
思维作翼，穿云破雾千重嶂
With thought as our wings, piercing clouds, breaking through fog and countless peaks
算筹为笔，演兵场上定攻防
With counting rods as our pens, on the training ground determining attack and defense
九章遗韵，奋进一流于湘江上
The legacy of Nine Chapters, we strive for first-class excellence along the Xiang River
初心如磐，我辈自可算定四方
Our initial resolve steadfast as rock, our generation can calculate to secure our land
