If the salinity(含盐量) of ocean waters is analyzed, it is found to vary only slightly from place to place.Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation--conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salts staybehind. If this is carried to the extreme, of course, white crystals of salt would be left behind.
The opposite of evaporation is precipitation(降水), such as rain, by which water is added to the ocean. Here the ocean is being diluted(稀释) so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by
the addition of fresh water by precipitation or runoff(形成地表水部分的降水).
Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions whererivers dilute the sea, salinity is somewhat lower than in other oceanic areas.
A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.
In the Weddell Sea, off Antarctica, the densest water in the oceans is formed as a result of this freezingprocess, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

It is easier to negotiate initial salary requirement because once you are inside, the organizational constraints (约束) influence wage increases. One thing, however, is certain: your chances of getting the raise you feel you deserve are less if you don’t at least ask for it. Men tend to ask for more, and they get more, and this holds true with other resources, not just pay increases. Consider Beth’s story:
I did not get what I wanted when I did not ask for it. We had cubicle (小隔间) offices and window offices.I sat in the cubicles with several male colleagues. One by one they were moved into window offices, while I remained in the cubicles, several males who wer
e hired after me also went to offices. One in particular told me he was next in line for an office and that it had been part of his negotiations for the job. I guess they thought me content to stay in the cubicles since I did not voice my opinion either way.
It would be nice if we all received automatic pay increases equal to our merit, but “nice” isn’t a quality attributed to most organizations. If you feel you deserve a significant raise in pay, you’ll probablyhave to ask for it.
Performance is your best bargaining chip (筹码) when you are seeking a raise. You must be able to demonstrate that you deserve a raise. Timing is also a good bargaining chip. If you can give your boss something he or she needs (a new client or a sizable contract, for example) just before merit pay decisions are beingmade, you are more likely to get the raise you want.
Use information as a bargaining chip too. Find out what you are worth on the open market. What will someone else pay for your services?
Go into the negotiations prepared to place your chips on the table at the appropriate time and prepared touse communication style to guide the direction of the interaction.
