balance of trade
trade balance
visible balance
trade gap | the difference in value over a period of time of a country's imports and exports of merchandise, a nation's balance of trade is favorable when its exports exceed its imports |
compensating balance
offsetting balance | a minimum credit balance that a bank may require a borrower to keep on deposit as a condition for granting a loan, a common requirement for establishing a line of credit at a bank, the compensating balance increases the effective interest rate to the bank since the net amount loaned is reduced but the interest paid is unchanged |

| carbon cycle | the organic circulation of carbon from the atmosphere into organisms and back again |
remainder
balance
residual
residue
residuum
rest | something left after other parts have been taken away, there was no remainder, he threw away the rest, he took what he wanted and I got the balance |
balance
equilibrium
equipoise
counterbalance | equality of distribution |
| balance | a state of equilibrium |
| balance of power | an equilibrium of power between nations |
| dynamic balance | (aeronautics) the state of equilibrium in which centrifugal forces due to a rotating mass (e.g., a propeller) do not produce force in the shaft and so vibration is reduced |
| electrolyte balance | an equilibrium between the amounts of electrolytes (as calcium and sodium and potassium) that is essential for normal health and functioning |
| nitrogen balance | the balance between the amount of nitrogen taken in (to the soil or the body) and the amount given off (lost or excreted) |
