Oppenheimer's trinity test marked the inception of the implosion-designed plutonium, eventually leading to the detonation of the Fat Man atomic weapon over Nagasaki.

奧本海默的三位一體試驗標誌著內爆設計鈈的誕生，最終導致 "胖子 "原子彈在長崎上空爆炸。

The outer charge explodes inward, followed by the inner ring of explosives creating a concave shockwave.

外層裝藥向內爆炸，隨後內圈炸藥產生凹形衝擊波。

It moves to the aluminium pusher, breaking the barren plastic sphere.

它移動到鋁製推杆上，打破了貧瘠的塑膠球體。

The shockwaves continue toward the uranium-238, it travels further compressing the plutonium sphere and compressing it more.

衝擊波繼續衝向鈾-238，並進一步壓縮鈈球，使其更加膨脹。

Interestingly, this was James' tuck idea, a British physicist who suggested employing shaped charges as three-dimensional explosive lenses, but it was further developed and perfected by Von Neumann, a Hungarian-American mathematician, physicist, and computer scientist.

有趣的是，這是英國物理學家詹姆斯的創意，他建議使用定型炸藥作為三維爆炸透鏡，但美籍匈牙利數學家、物理學家和計算機科學家馮-諾依曼進一步發展和完善了這一創意。

So stay tuned as we move to explore the step-by-step process of how this Fat Man atomic weapon worked, all in the videos ahead, so don't miss a beat.

敬請期待，我們將在接下來的視頻中一步步探究 "胖子 "原子武器的工作原理，敬請期待。

Starting from the back, this is the California Parachute Tail.

從後面開始，這是加利福尼亞降落傘尾部。

It was meant to stabilize the weapon when dropped.

它的作用是在武器掉落時保持穩定。

Next we have the Barrow-2 Collector, which helps measure the altitude of the bomb.

接下來是巴羅-2 收集器，它有助於測量炸彈的高度。

This section contains the barrow switches, radar, and timers.

本節包含小車開關、雷達和計時器。

Moving further ahead, these are some of the 32 detonator wires connected to this X-unit if firing is set placed near the charge.

再往前走，如果在裝藥附近設置點火裝置，這些是連接到這個 X 型裝置上的 32 根雷管導線中的一些。

These are the 24-volt batteries required to detonate the charge surrounding the nuclear components.

這些是引爆核部件周圍裝藥所需的 24 伏電池。

Moving to the exterior of the weapon are these three arming plugs removed before dropping from the B-29 plane.

從 B-29 飛機上卸下武器前，這三個引爆塞被移到武器外部。

These are the four Archie radar antennae that activates when the bomb reaches a suitable height.

這是四個阿奇雷達天線，當炸彈到達適當高度時就會啟動。

Finally, at the front, we find the 4A end-destruct fuse.

最後，在前端，我們找到了 4A 的末端自毀保險絲。

This device was made to self-destruct the weapon so as not to fall into the hands of the enemy when each of the firing mechanism fails to activate.

該裝置可使武器自毀，以免在每個發射裝置失靈時落入敵人手中。

Let's dive into the interior of this weapon.

讓我們深入瞭解一下這款武器的內部結構。

The core of the assembly is the internal neutron initiator.

組件的核心是內部中子引發器。

This is responsible for emitting neutrons essential for the chain reaction.

它負責發射鏈式反應所必需的中子。

It contains a beryllium pallet and a beryllium shell with inward-pointing spikes, and between them is polonium, a radioactive substance emitting alpha particles.

它包含一個鈹托盤和一個帶有向內尖刺的鈹殼，兩者之間是釙，一種發射α粒子的放射性物質。

The entire neutron generator assembly is 2 cm in diameter.

整個中子發生器組件直徑為 2 釐米。

Surrounding the neutron generator is the main fusion material, around 6 kg plutonium sphere measuring around 9 cm in diameter.

中子發生器周圍是主要的聚變材料，約 6 千克重的鈈球，直徑約 9 釐米。

Enclosed within this sphere is another concentric sphere made of uranium-238, acting as a neutron reflector to increase fission efficiency and contribute to the fission reaction.

在這個球體中，還包裹著另一個由鈾-238 組成的同心球體，作為中子反射器來提高裂變效率並促進裂變反應。

On the uranium sphere lies a thin layer of plastic shell, made of acrylic thermoplastic enriched with boron.

鈾球上有一層薄薄的塑膠外殼，由富含硼的丙烯酸熱塑性塑膠製成。

Its purpose is to absorb slow-moving neutrons and prevent pre-detonation.

其目的是吸收慢速中子，防止預爆。

The critical components for the fission reaction are enclosed in a thick layer of aluminum, known as an aluminum pusher, which uniformly transfers shock waves from the explosives to the uranium.

裂變反應的關鍵部件被包裹在厚厚的鋁層（稱為鋁推流器）中，鋁推流器能將炸藥產生的衝擊波均勻地傳遞到鈾中。

The pusher sphere of aluminum is surrounded by 32 blocks of faster explosives, a combination of 61% RDX and 39% TNT.

鋁製推杆球體周圍有 32 塊速效炸藥，其中 61% 為 RDX，39% 為 TNT。

An additional layer of 32 explosive blocks lies outside, forming an explosive lens to shape the detonation wave.

外面還有一層由 32 個爆炸塊組成的爆炸透鏡，以形成爆炸波。

Each explosive block contains a detonator for initiation.

每個炸藥塊都有一個起爆雷管。

This assembly is referred to as the physics package, encased in a thick steel case to contain the explosion of fast and slow explosives.

這個組件被稱為物理包，包裹在一個厚厚的鋼殼中，用於容納快速和慢速炸藥的爆炸。

Simultaneous detonation of all explosive blocks is crucial for a symmetric explosion.

同時引爆所有炸藥塊對對稱爆炸至關重要。

Lastly, the X-unit, an electronic component with capacitors, produces high current, high voltage and distributes it simultaneously to all 32 detonators via wires with thick insulation.

最後，X-單元是一個帶有電容器的電子元件，可產生大電流和高電壓，並通過絕緣層較厚的導線同時分配給所有 32 個雷管。

Let's look at the basic step-by-step process.

讓我們來看看基本的分步流程。

Boeing B-29 Superfortress acts as the primary transport.

波音 B-29 超級堡壘作為主要運輸工具。

Before opening the bomb bay doors, all three arming plugs are pulled one after the other.

在打開炸彈艙門之前，要逐一拔出所有三個引爆插頭。

The doors open and the bomb falls due to gravity.

門打開後，炸彈在重力作用下墜落。

Then it switches to its internal 24-volt battery and starts the timer.

然後，它切換到內置的 24 伏電池，啟動計時器。

After 15 seconds, the barometer senses the desired height.

15 秒後，氣壓計感應到所需高度。

The membrane closes circuit, activating the multiple radar altimeters located at the front of the bombs.

薄膜閉合電路，激活位於炸彈前端的多個雷達高度計。

The barometric stage was added because of a worry that external radar signals might detonate the weapon too early.

之所以增加氣壓級，是因為擔心外部雷達信號可能會過早引爆武器。

To ensure accurate detection of the final altitude, multiple radar altimeters were utilized.

為確保準確探測最終高度，使用了多個雷達高度計。

This process involves measuring the altitude above the ground beneath the aircraft or the fat man through the timing of radio wave's travel, reflection and return.

這一過程包括通過無線電波傳播、反射和返回的時間來測量飛機或 "胖子 "下方的地面高度。

Once the correct height was sensed, the X-firing switch activates and sends signals through the 32 wires to set bridge charge detonators.

一旦感應到正確的高度，X 點火開關就會啟動，並通過 32 根導線發送信號，以設置橋式裝藥雷管。

The outer faster charge explodes inwards followed by the inner ring of explosives creating a concave shockwave.

外圈的快速裝藥向內爆炸，隨後內圈的炸藥產生凹形衝擊波。

It then travels to the aluminum pusher breaking the barren plastic sphere.

然後，它到達鋁製推杆，打破了貧瘠的塑膠球。

The shockwaves further travel towards the uranium 238.

This makes the plutonium sphere denser compressing it further in the process.

這使得鈈球密度更大，並在此過程中進一步壓縮。

This is the final part of the process where the extreme forces crush the beryllium shell and the polonium releasing neutrons required for fission reaction.

這是裂變過程的最後一部分，在這一過程中，極端的力量會擠壓鈹殼和釙，釋放出裂變反應所需的中子。

The neutron strikes the nucleus and is absorbed.

The absorbed neutron causes the nucleus to undergo deformation.

被吸收的中子會導致原子核變形。

The nucleus fission releases an average of 2 or 3 neutrons, thus creating a chain reaction or in some words an explosion.

原子核裂變平均會釋放出 2 或 3 箇中子，從而產生連鎖反應，或者用某些詞來說就是爆炸。
