中文翻译：生存时间（Time To Live）
读音：tɪtl，或读作“提提儿”
例句：
1. 协议规定，IP数据包的生存时间不得超过TTL值。
The protocol stipulates that the Time To Live value of an IP packet should not exceed its TTL value.
2. TTL为0时，数据包将被丢弃。

1. 定义及用途方面
- TTL是英文“Time To Live”的缩写，通常用于计算机网络中，表示某个数据包可以穿过多少跳（hop）路由器后失效。
- TTL还可以用于其他领域，如生物学中的细胞存活时间等。
- 除了TTL，还有类似的缩写词，如TTF（Time To Failure）、TTS（Time To Service）等。
例句：
1. The TTL for this packet is set to 64.
2. The TTL on this job offer is two weeks.
3. The TTL of red blood cells is about 120 days.
4. It's important to monitor the TTL of your company's products.
5. The manufacturer claims a TTL of 10,000 hours for this light bulb.
2. 技术方面
- TTL是一种二进制逻辑家族，由门电路、触发器等组成，广泛应用于数字电路设计领域。
- TTL电路的主要优点是速度快、功耗低、可靠性高等。
- TTL电路还有多种变种，如LS-TTL（Low-power Schottky TTL）、HCT-TTL（High-speed CMOS TTL）等。
例句：
1. The TTL gate provides a logical 1 output when both inputs are logical 0.
2. The TTL IC is widely used in microprocessor systems.
3. The LS-TTL family is known for its low power consumption.
4. HCT-TTL offers faster switching speeds than regular TTL.
5. TTL logic can be cascaded to form complex circuits.
3. 艺术设计方面
- TTL也可以是艺术和设计领域的缩写，代表“Through The Lens”或“Through The Looking-glass”。
- Through The Lens通常指摄影师通过相机的镜头来观察拍摄对象，以及用镜头来表达自己的视觉风格。
- Through The Looking-glass则源自于Lewis Carroll的小说《爱丽丝梦游仙境》中的一个场景，意为“通过镜子看到另一种世界”。
例句：
1. The TTL approach to photography emphasizes composition and lighting.
2. The TTL exhibit showcases the work of emerging photographers.
