return circuit
6.6 type products whether one have whorl, card lock connection device of organization, it apply to post and telecommunications communication equipment, figure buy the line device extensively, The radio instrument waits until joining the coaxial cable of the radio frequency to use in the radio frequency return circuit, And can change each other with the products that IEC60169-13 stipulate.
10.Related elucidation:in the above data, from the entry-level pure water to pure water, it measures to 75% for.Namely each 1.25 rise the entry-level pure water can produce pure water 1 rise, the running water system is pure aqueous of parameter is also such, from above the data can see, in make take the circuit plank the production have to of the purely aqueous process, adoption collections waste water of way, make the waste water get and return and use in water, reduce waste water and exhaust in the meantime, in this process, not only a great deal of decrease the waste water exhaust quantity, and list make water cost but talk, use waste water each time produce on signing square and pure water, can decline low cost 0.34 dollars at least, more important can lower waste water and exhaust quantity consumedly.
