1. The neutron may be considered in fact as being exposed to a time-dependent electric field.
.
2. On the basis of the product being a single isomer, the intermediate radical appears to react with iodine. , , , .
3. It was only in 1781 that Emerson invented the process of direct fusion of the metals to produce a copper zinc alloy we call brass. 1781 , , .
4. The refractive index of amorphous selenium at a wavelength of 2.5 microns has been reported to be 2.46 or 2.44 by different authors. 2.5 , 2.46 2.44 .
5. The equal spacing between components appears to make double flip-flops possible in most configurations. .
6. They succeeded in obtaining good results working with quicksilver, it being known to be a very dangerous metal. , .
7. It is desirable that the output signal should be a linear function of the input signal; any deviation from linearity is called distortion and is highly undesirable. , , , .
8. The effect is highly dependent on frequency with the lower frequencies showing less noise. , .
9. From what has been said so far, one might think that alternating current has little advantage over a direct current. , - .
10. The best compromise is to select a low-coefficient fixed inductance. .
11. It should be stated that we are assuming throughout this chapter that the primary condition that the system be stable is already satisfied. , .
12. Such fluctuations, being sensitive to the exact location of channel boundaries, would not be expected to reproduce in successive determinations. , , .
13. On close examination of a piece of granite we find it to be composed of several kinds of minerals having different degrees of hardness, different colours, and different properties in general. , , .

14. This value is subject to systematic errors, the most important one reflecting our lack of knowledge of the energy spectrum. , .
15. The material damping is considered in a manner which seems to be as exact as it can be without the use of nonlinear equations. , .
16. Should extreme gain stability be required, it can be achieved without degrading the noise figure. .
17. The original signal is reconstituted thereby, with the noise impulses smeared. .
18. The occurance of metals in the earth's crust is unequal, some of them being plentiful, the other existing only in small quantities. , , .
19. The curves of Figs. 15 and 16 show a much smaller rate of change of gain with pump voltage than do those of Fig. 8. 15 16 8.
20. In the lower latitudes, the down and dusk periods will last about two hours. 2 .
