寬扁麵麵條扁平，斷面為橢圓形，因為容易蘸附醬汁，料理不需加入太多醬料，即能顯現食材風味。
在義大利不管是餐廳或家庭，大部分的人都偏好自己做義大利麵，口感和味道與乾燥過的義大利麵完全不同，煮的時間也減少許多，
市面上乾燥義大利麵是用麵粉和水做成，新鮮的手工義大利麵則使用杜蘭小麥粉和全蛋做成，想吃到新鮮的義大利麵不用再去餐廳，這裡也能讓你嚐到最新鮮的美味 !
*醬汁搭配:可在醬汁頁面選購
*一份80~85g，約一人份
建議烹飪:熱水燒滾後，加入麵條，約1~2分即可試吃
煮到自己喜歡的軟硬度即可!
Linguine noodles are flad and their cross section is oval. Not much sauce is required when cooking them since they are easily coated. This also allows the fresh pasta flavor to shine through.
In Italy, whether at a restaurant or at home, most people prefer to make their own pasta. The texture and taste is completely different to that of dried pasta, and the cooking time is greatly reduced.
Mass produced dried pasta is made with flour and water, whereas fresh pasta is made with durum wheat and whole eggs. If you want to have fresh pasta in Taiwan, you no longer need to go to a restaurant. Order from us and taste this freshest delicacy!
Sauce pairings available on the sauce page.
A serving is 80~85g. And is enough for one person.
Suggested cooking method:
Bring water to a boil and add the noodles. Test after one or two minutes to see, then cook to your preferred texture.

one to one 在 [離散] One-to-one or Onto ？ - 精華區Math - 批踢踢實業坊 的推薦與評價
Let X be a set. Define a map d: X -> X*X by d(x) = (x,x).
a) Is d one-to-one? Prove or disprove.
b) Is d onto? Prove or disprove.
直接看的話我覺得應該是 one-to-one
只是我不知道要怎麼寫證明...
這邊想請問一下先進們關於one-to-one 跟 onto的差別
one-to-one 指的是說每個x都會對應到一個y
而
onto則是說一個y不一定只會被一個x對應到
是這樣的意思嗎？？ 我看課本還是看不太懂是在講什麼
課本上對one-to-one的定義
f:X->Y
For all a and b in X,f(a) = f(b) implies that a=b. In this case we say that
f is a one-to-one mapping from X to Y
課本上對onto的定義
f:X->Y
for all y 屬於 Y,there exists an x 屬於 X such that f(x) =y. In this case
we say that f maps X onto Y.
onto 這邊我還是不太懂，課本上的圖解好像是說每個x都只會（一定會？）對應到一個y
如果要解釋的話是這樣解釋嗎？
麻煩各位解惑了，謝謝！
