 487  89. The curvature of the anode-current grid-voltage characteristic of the valve gives rise to distortion. 90. The charge of an atom, however, is not affected by the number of neutrons present but depends on the balance between electrons and protons. 91. The design process can be speeded by starting with families of curves in all but the transistor quadrant. 92. The second quantitative relationship concerns the amount of endogenus pyrogen, which may be present in the donor's circulation, over and above that needed for the production of maximum fever. 93. All life ultimately depends on absorption of light, for it is the absorption of sunlight by the green leaves of plants which keeps the plant and animal world alive. 94. For automatic system to be successful it must tune a transmitter at least as accurately as can be done manually. 95. The maintenance of a temperature within a prescribed range under conditions of varying thermal loads can be termed temperature regulation. This does not necessarily mean maintenance of constant heat content. 96. However plentiful the ore may be the extraction of a metal will not be profitable unless it is sufficiently suitable for some purpose to be sold at a price that will pay for extraction. 97. The effects of high vacuum and van Allen belt radiation on organic materials commonly used in electronic equipment were of particular concern. 98. As rate control is sensitive to the rate of change of the temperature it recognizes at once the magnitude of the imposed thermal load. For this reason the rate control is sometimes known as «anticipatory» control. 99. It is not possible for the authors to make all the mathematics involved easy for those who have little training in that subject, since many of the arguments and processes are difficult and complex. 100. If a particular message is of great importance, the power may be easily increased at the expense of other links. 487 |
