3.Based on heat-oxygen balance, some calculation formulae were derived. Thereby, vertical eddy coefficient, increase rate of vertically mixing oxygen, netincrease rate, total increase rate and consumption rate of oxyen in biochemical processes were solved .
4.Here comes a population problem. Last year there was a netincrease of more than 13 million people. This year there may be another netincrease of 20 million. By 1970 we shall have a population of 800 million.
8.It works out to be about 1.6 percent annual netincrease. In numbers this means something like forty to forty-five million additional people every year.
9.By the end of 2001, the number of people participating in the general retirement security program saw a netincrease of 207,000, thoroughly reversing the downward trend in the number of people paying contribution for the program.
10.With such an immense population base, China, despite the implementation of birth control, still sees a yearly netincrease of 17 million people, a number equal to the population of a medium-sized country.
