一、在物理學里的M、c、r、G、F、E、m分別表示什么物理量？

F表示萬有引力，M，m都表示質(zhì)量，c表示光速、r表示所研究兩物體之間的距離、G表示引力常量，E表示能量。

二、E-R圖轉換為關系數(shù)據(jù)模型?

去看看百度文庫：將E-R圖轉換為關系模型的轉換規(guī)則 和E-R圖向關系模型的轉換。網(wǎng)址： 和 會對你有幫助的。

Teenage Mutant Ninja Turtles arcade game:

Got to level 9-1 and get the hidden Antique. Do this by going down

one of the alleyways. There will be a pile of crates and a broken

down bus. Jump on the crate and onto the bus. From the bus, jump

onto the building . There should be two crates here, containing

Pizza and the Antique. Then, complete the level and defeat all the

Purple Dragons, Foot, and Mobsters. Next, go to the 2nd Time

Around. If you look through the different objects in the NY

section, you will see the image of an arcade. Select the arcade to

see information on it. When you exit out of the information, the

message Classic Arcade Mode Unlocked will appear, and that option is now on the main menu at the title screen. Note: Do not worry if the screen remains black, or the arcade main screen takes a long time to load; this is normal.(Arc模式：9-1關，在一個小巷里有個破的公交車，通過他上到房頂，打開兩個箱子，吃到寶箱，通關后，回到家里，看2nd Time模式，里面有張卡片，上面畫著一個街機，看介紹后推出，屏幕上會出現(xiàn)“Classic Arcade Mode Unlocked，然后退到主畫面，出現(xiàn)街機模式.)

*****后面由于沒弄出街機模式，所以沒有測試***

In the arcade game, press Circle to get more lives instead of

quarters. The joystick and certain buttons including the pause

feature do not work. The character selection is just like the

arcade. Each controller controls a different turtle. You cannot

which turtle to assign to a controller. Controller one is Leonardo,

controller two is Michaelangelo, controller three is Donatello, and

Controller four is Raphael.

Glitch: Character's feet pass through wall:

Whenever you do a wall-jump, look very carefully to see that your

character's toes (or sometimes even their feet) are passing through

the wall.

ARC模式我沒有弄出來，可能還需要什么條件，這里面所說的方法我試過了，沒有成功。
