跪求時光倒流一句話
👍🏻😃謝謝提議。會考慮的
很喜歡你的編譜👏🏼👏🏼👏🏼
在你指尖下彈奏每個音符都是優美動聽，輕柔雅淡，好好聽呀!
謝謝您村長👍🙇♀️
謝謝您啊😄😄
好好聽😍😍會否cover 神奇的糊塗魔藥？
謝謝推薦歌曲啊😄會聽聽的👍🏻

！！！
正！繼續支持🥰
😁🙏🏻謝謝
Jeng!
Nice, everything is there
Very nice
竉物情人(小肥)......
you are a real talent!
Thanks so much. Glad you liked it😃
拼命無⼂⼃⼀
好聽
Good!
好听👍
村长啥时候出一期不一样的👀可以给我们拍拍工作室啊、讲讲鱼蛋村的往事啥的。鱼蛋村成立这么久了，老弹琴多没意思✔️
這是我想做, 但不知如何做起的東西😂
@@yudan730 🤔
Nice
👏👏👏
請問可否Cover 銀髮白？Thanks.
多謝提議:D 等我聽聽先
音準好棒 🎼 能彈彼個所在嗎
謝謝提議歌曲👍🏻😃會聽聽的
村长 如何才能保证一整首歌(3或4分钟以上)里都不会错一个音，大难了！
先處理重要的，再處理微細的
@@yudan730 看来不容易😂，可能我现在还办不到
你平均一首彈多少次才錄成？我成日都有彈錯有瑕疵😓
你好,請問能夠拿來出唱歌cover嗎?會註明出處
如果想借用cover,可電郵查詢啊😃yudansnet@gmail.com
(2310-4.1) Energy Balance （原曲：林家謙-下一位前度）（2019）
V1: Net Energy transfer Equals to all delta E
In piston, PdV, Area under process curve's W
Both PV's difference over 1 minus n, polytropic
P delta V, constant P
And PV log ratio of Vs isothermal
V2: Q minus W, delta U, cause no KE or PE here
P delta V is W b, Q minus that, W other, it's delta U
This Equals to delta H, m(h2 minus h1)
Since the pressure is constant, there is nothing wrong
It's used for constant pressure expansion contraction
C: Remember E in minus E out
Equals to delta E of system
Delta U plus boundary work is delta H
Enthalpy is U plus PV
It's just Q minus W other
Used in closed system under constant pressure
V3: Stationary zero KE PE change process
Insulated negligible heat transfer, E's zero, no work interactions
Then you form equation, it's just so straightforward
Then you can visualize it on PV diagram
Find quantity with pure substance properties or ideal gas law
(Repeat C)
B: Find your P V T all by the tables
Find x in final state, judge it and find T
Then u is just u f times x u fg
If ideal gas, make sure you have V and P
Then you have drawn your PV diagram
You just take area, or use the right process formula
(Repeat C)

乜嘢嚟。。。
从哪个视频开始你露脸了啊，哈哈哈
我都忘了。近來都經常露臉🙈
