一网工程天幕下的博弈第三章跨界的火花。 发改委环境工程司的会议室里弥漫着咖啡和打印纸的味道。 赵刚推过来的测试报告上密密麻麻的曲线像一群扭动的蛇,那是不同频段电磁波穿过薄膜后的衰减率。 林野的目光死死盯在15千兆赫兹的位置,那里的曲线几乎垂直下坠,旁边的数字标着百92,聚酰亚胺基材本身不导电,赵刚用激光笔点着报告上的分子结构图,但我们在表面做了铝基纳米涂层,厚度只有300纳米,既能反射阳光,又能像金属网一样屏蔽特定频段,12~18千兆赫兹正好是它的共振吸收区,信号进去就出不来。 林野拿起桌上的样品,一块巴掌大的薄膜,薄的像蝉翼。 对着光看能透出朦胧的亮,他试着弯折,薄膜在指尖灵活的卷曲,展开后却依旧平整。 这东西在350公里轨道上能展开到1.2平方公里,理论上可以。 赵刚笑了笑。 我们做过地面张拉测试,折叠比能到1:1000,像把雨伞一样从卫星里撑开。 但有个问题,他话锋一转,调出轨道参数图。 350公里轨道有稀薄大气,薄膜展开后会受阻力影响,轨道每天会降1.5公里。 我们的解决方案是配小型离子推进器,每月点火一次维持轨道。 林野的手指在参数表上滑动。 离子推进器功率、燃料储备、薄膜耐辐射寿命,这些数据像拼图一样在脑子里慢慢成型。 如果把它部署在星链低轨卫星的正上方,他突然开口,声音有些发紧。 350千米的高度正好能覆盖星链卫星与地面终端的凸形链路。 当星链卫星过境台海时,我们让薄膜展开,15分钟后收回,相当于在信号传输的嗓子眼上捂了块布。 赵刚 接过话头,镜片后的眼睛亮了。 你们不是要摧毁卫星,是让它在特定区域失声。 会议室的空气仿佛凝固了。 林野看着赵刚,这个研究了10年如何给地球遮阳的工程师,此刻比任何军事专家都更懂他的想法,但有三个坎。 赵刚敲了敲桌子,语气严肃起来。 第一,薄膜展开的时机。 星链卫星过境台海的时间窗口只有10~15分钟,必须分秒不差,否则要么等早了浪费燃料,要么等晚了没效果。 他调出星链的轨道预测模型,密密麻麻的红点在屏幕上移动。 第二,选择性屏蔽。 你们的 军用通信不能被挡住吧?我们得在图层里加频率窗口,让特定频段能穿透,这需要重新设计图层的纳米结构。 第三,成本。 赵刚看着林宇,天蓬计划的单星成本是800万人民币,这是民用标准,如果要加机动变轨能力、精准定时系统,成本至少翻一倍。 你们 能接受吗?林野想起总参文件里星链的成本数据,50万美元一颗,约合350万人民币,1600万一颗。 他迅速心算,比反卫星导弹便宜80%,但他们的卫星贵4倍。 不需要像他们那样发2万颗,3颗,不,5颗就够了。 赵刚愣了一下,随即笑了。 你们军人算账真直接,不过我提醒你,这东西本质上是太空软干扰,对方可以通过调整卫星轨道避开,比如把星链的低轨高度降到330千米,或者提高到360千米,都能绕开我们的薄膜。 那就让我们的卫星能追。 林野的语气很坚决。 你们的离子推进器能不能改的更灵活?比如根据星链的轨道变化。 每天微调一次高度。 赵刚沉默了片刻,在电脑上敲了串公式,然后抬头,可以,但燃料消耗会增加30%,卫星寿命从5年降到3年。 够了。 林烨站起身,窗外的阳光透过百叶窗,在他脸上投下明暗交错的条纹。 三年足够改变很多事了。 离开发改委时,林野手里攥着那份测试报告,纸边被捏得发皱。 走廊里,他听见赵刚团队的讨论声传来。 把涂层的纳米孔径调到0.1微米试试,说不定能让军用频段的穿透率提到99%。 他突然想起赵刚最后说的话。 林参谋,你们总说军民融合,其实有时候民用技术的天花板就是军用创新的起跑线。 我们研究如何让阳光照进来,你们研究如何让某些光照不进来。 本质上都是在玩频率的游戏。 车窗外,长安街的车流缓缓移动。 林野看着窗外掠过的高楼,脑子里反复回放着那个画面。 350公里之上,一层薄薄的薄膜在星链卫星前方展开,像一只精准罩住蝉鸣的手。 他拿出手机给总参作战部发了条信息。 找到破局思路,去环境工程咨询所申请跨部门立项。 发送成功的提示弹出时,林野靠在椅背上,长长的舒了口气。 三天来压在心头的巨石似乎终于有了松动的迹象,而他知道 这仅仅是开始,从一张遮阳膜到一张太空屏蔽网,中间隔着的是无数个需要跨越的技术鸿沟,和一场注定不会平静的博弈。

The Game Under the Skynet Dome Chapter 3: Sparks Across Borders The meeting room of the NDRC's Environmental Engineering Department was filled with the scent of coffee and the smell of printed paper. The test report pushed over by Zhao Gang was covered in dense curves, twisting like a group of snakes—attenuation rates of electromagnetic waves passing through the film at different frequencies. Lin Ye's gaze locked onto the 15 GHz position, where the curve plummeted almost vertically. The number next to it read 92. *The polyimide substrate itself is non-conductive*, Zhao Gang pointed with a laser pen at the molecular structure diagram on the report, *but we applied an aluminum-based nano-coating on the surface, only 300 nanometers thick. It reflects sunlight while acting like a metal mesh to shield specific frequency bands. The 12–18 GHz range falls right into its resonance absorption zone—signals go in but can't get out.* Lin Ye picked up the sample on the table—a palm-sized film as thin as a cicada's wing. Holding it up to the light, he could see a faint glow. He tried bending it, and the film curled flexibly under his fingers, yet remained flat when unfolded. *At an altitude of 350 kilometers, this thing can expand to 1.2 square kilometers. In theory, it works.* Zhao Gang chuckled. *We've done ground tension tests. The fold ratio can reach 1:1000, deploying like an umbrella from the satellite. But there's a problem.* He shifted tone and pulled up an orbital parameter chart. *At 350 km, there's a thin atmosphere. Once deployed, the film will experience drag, causing the orbit to decay by 1.5 km per day. Our solution is to equip it with a small ion thruster, firing once a month to maintain orbit.* Lin Ye's finger slid across the parameter table. Ion thruster power, fuel reserves, film radiation lifespan—all these pieces slowly assembled into a picture in his mind. *If we deploy it directly above Starlink's low-orbit satellites,* he suddenly spoke, his voice a bit tight, *the 350 km altitude can exactly cover the convex link between Starlink satellites and ground terminals. When a Starlink satellite passes over the Taiwan Strait, we expand the film and retract it after 15 minutes. It's like putting a cloth over the throat of signal transmission.* Zhao Gang picked up the thread, his eyes behind his glasses lighting up. *You're not trying to destroy the satellite—just mute it in a specific area.* The air in the meeting room seemed to freeze. Lin Ye looked at Zhao Gang—this engineer who had spent ten years researching how to shade the Earth was now understanding his thoughts better than any military expert. *But there are three hurdles,* Zhao Gang tapped the table, his tone serious. *First, the timing of deployment. The Starlink satellite's window over the Taiwan Strait is only 10–15 minutes. It has to be precise to the second—deploy too early and waste fuel, too late and lose effectiveness.* He pulled up Starlink's orbit prediction model; dense red dots moved across the screen. *Second, selective shielding. Your military communications can't be blocked, right? We need to add frequency windows in the coating to let specific bands pass through. That requires redesigning the nano-structure of the layer. Third, cost.* Zhao Gang looked at Lin Ye. *The unit cost of the Tiantong Plan satellite is 8 million RMB—that's a civilian standard. If we add maneuverability and precision timing systems, the cost will at least double. Can you accept that?* Lin Ye recalled the cost data for Starlink satellites in the general staff document: $500,000 each, about 3.5 million RMB. *Our 16 million each,* he quickly calculated. *80% cheaper than an anti-satellite missile, but our satellite is four times more expensive. We don't need to launch 20,000 of them—just 3, no, 5 will suffice.* Zhao Gang was taken aback for a second, then laughed. *You military types sure are direct with numbers. But I should warn you—this is essentially a soft-space jamming device. The opponent could avoid it by adjusting satellite orbits. For example, lowering Starlink's orbit to 330 km or raising it to 360 km would bypass our film.* *Then let our satellite chase them,* Lin Ye's tone was resolute. *Can your ion thruster be made more flexible? For instance, adjusting altitude daily based on Starlink's orbital changes.* Zhao Gang was silent for a moment, typed a formula into his computer, then looked up. *Yes, but fuel consumption will increase by 30%, reducing satellite lifespan from five years to three.* *That's enough.* Lin Ye stood up. Sunlight streamed through the blinds, casting alternating light and shadow across his face. *Three years can change a lot.* As he left the NDRC, Lin Ye clutched the test report, its edges crumpled in his hand. In the corridor, he overheard Zhao Gang's team discussing: *Let's try adjusting the nano-pore diameter to 0.1 microns. Maybe we can boost military-band penetration to 99%.* He suddenly recalled Zhao Gang's parting words: *Captain Lin, you always talk about civil-military integration. Sometimes the ceiling of civilian technology is the starting line for military innovation. We study how to let sunlight in; you study how to keep certain light out. In essence, we're both playing the frequency game.* Outside the car window, traffic on Chang'an Avenue crawled slowly. Lin Ye looked at the high-rises flashing by, replaying a scene in his mind: 350 kilometers above, a thin film unfurls in front of a Starlink satellite, like a hand precisely cupping a cicada's chirp. He pulled out his phone and sent a message to the General Staff Operations Department: *Found a breakthrough idea. Apply for cross-department project approval at the Environmental Engineering Consulting Office.* When the "sent" notification popped up, Lin Ye leaned back in his seat and let out a long sigh. The boulder that had weighed on his chest for three days finally seemed to loosen. And he knew this was only the beginning—from a sunshield film to a space shielding net, countless technical chasms lay ahead, and a game destined to be anything but calm.
