上一篇StableDiffusion文生图我们了解了基本概念，本篇文章详细介绍下prompt（提示词）。本篇文章如果无特殊说明，演示使用sd_xl_base_1.0.safetensors的基础模型，这个模型可以更好的理解自然语言，尺寸 1024 * 1024，固定随机种子（Seed）。
提示词
prompt，提示词，简单说就是你对图片的描述（这个很重要），我们从最简单的开始，不断修改提示词展示不同提示词的效果：
a cat
a running cat
a cat running inside the house
a close-up shot of a cat running inside the house
可以看到对自然语言的理解已经很好了，基本能够满足我们的需要，我们给一些更复杂的提示词，看看效果。
a 3D-rendered cat bathing
a 3D-rendered cat bathing with continuous flowing water, while nearby flowers bloom
a 3D-rendered cat wearing a crown, bathing with water flowing continuously, while nearby flowers are blooming.
可以发现已经很友好了，你需要什么效果直接写提示词，基本能够满足我们的需要
接下来看看多个物体的提示词，看看效果。
Two cats, a kitten, and an adult cat playing inside the room
Two cats, one kitten, frolicking in a room, captured in a candid, portrait-style photograph
多个物体的数量控制不是太准，这个需要使用反向提示词进行修正。
反向提示词
negative prompt，反向提示词，即你不希望画面中出现的元素。
上面的两只小猫的prompt，出现了4只，你就可以在反向提示词中加入 four cats ，禁止出现四只。
prompt：Two cats, one kitten, frolicking in a room, captured in a candid, portrait-style photograph
Negative prompt：four cats
Negative prompt：four cats, running
Negative prompt：four cats, three cats, running
上面这两个是基本文生图的基本概念，好理解但是需要大量的实验来验证我们的描述。
实战文生图
我们可以对提示进行加强（提示词:N），N就是你要加强的倍数，比如下面的提示中我加强了王冠：(crown:2)
我们通过山海经中的描述来生成图片
有兽焉，其状如禺而白耳，伏行人走，其名曰狌狌，食之善走——出自南山经
这里的狌狌同猩猩
译文：In the mountains, there is a creature resembling a macaque but with white ears. It moves by crawling on its belly and can also walk upright like a human. This creature is called the "Qian Qian". Eating its meat allows one to run faster
prompt（提示词）：In the mountains, there is a creature resembling a macaque but with white ears. It moves by crawling on its belly and can also walk upright like a human.
prompt（提示词）：In the mountainous wilderness, a creature resembling a macaque, yet distinguished by its white ears, gracefully moves with a posture akin to crawling, yet also possesses the remarkable ability to stand erect like a human. Adorned with a majestic (crown:2), it sprints through the rugged terrain, its regal bearing and extraordinary form commanding attention amidst its natural habitat.
prompt（提示词）：In the vast expanse of space, a creature reminiscent of a (macaque:2), yet distinguished by its (white ears:2), gracefully navigates the cosmic void. With a curious gait resembling crawling, it seamlessly transitions into walking upright like a human. Clad in a sleek spacesuit, it dashes through the weightless environment.
今天先说到这里，其实学习是一个过程，不可操之过急，需要循循善进！
