Plus sign

One or two plus signs can also be added, such as 6—31+G or 6—31++G. A single plus sign indicates that diffuse functions have been added to atoms other than hydrogen. The second plus sign indicates that diffuse functions are... 

Note The plus (+) signs provide only a qualitative guide and should not be construed as a definitive assessment. The greater the number of plus signs, the more advantageous the system. 

The plus sign indicates a positive sequence harmonic and the minus. sign a negative sequence harmonic. Their effect is same as for the positive and the negative seqtience components discussed in Section I2.2(v) and ctiuses pulsation in the magnetic field and hence, in the torque of a rotiitimi machine.

Ihe arrow points toward the negative end of the polar bond (F atom) the plus sign is at the positive end (H atom). Ihe HF molecule is called a dipole it contains positive and negative poles. 

Here v the stoichiometric factors of the i the compound used in the equation for the cell reaction, having a plus sign for the substances formed and a negative sign for the compounds consumed.

Fig. 18-11 Records of atmospheric CO2 in Antarctica for the past 1000 years. Open circles are ice-core data from Law Dome, on the coast of east Antarctica (Etheridge et al., 1996). Plus signs are direct measurements of CO2 in air samples collected monthly at the South Pole (NOAA Climate Monitoring and Diagnostics Laboratory, Boulder, Colorado).

The equation for the confidence limit is Y = A + B- x t-VVres + (x - Xmean) / cx). where X is time. Minus sign for main component plus sign for impurity. 

The energy of an ion in a given medium depends not only on chemical forces but also on the electrostatic held hence the chemical potential of an ion j customarily is called its electrochemical potential and labeled fi. The electrostatic potential energy of an ion j when reckoned per mole is given by ZjF, where / is the electrostatic (inner) potential of the phase containing the ion a plus sign for cations and a minus sign for anions. Hence, the electrochemical potential can be written as the sum of two terms ...

The charges of ions are designated with superscripts placed beside the symbol for the ion. For example, a hydrogen ion is abbreviated H+. The letter H is the chemical symbol for hydrogen. The superscript plus sign shows that the hydrogen ion has... 

Although the net results obtained above for the particle in a box are physically the same, the mathematieal consequences are quite different. From Fig. 4b it can be seen that the wavefunction is either even or odd, depending on the parity of n. Specifically, ifrtt(x) = iM— ) where the plus sign is appropriate when n is odd and the minus sign when n is even. As Eq. (70) contains the sine of the sum of two terms, it can be rewritten in die form... 

For a mixture of two gases—gas 1 and gas 2—put in equal signs or plus signs in the appropriate places in the equations below ... 

Two solutions for x (one with the plus sign and one with the minus sign) can be obtained from this formula, but only one will have physical meaning. For example, there can be no negative concentrations. Solving this problem exactly yields... 

The plus sign corresponds to the downstream transition and the minus sign to the upstream one. This equation is solved along each path beginning at the respective end points—the initial condition of the bed for the downstream transition and the feed condition for the upstream transition. If either path fails to evolve continuously in the expected direction, the difference form, from Eq. (16-136),...

Fig. 5.11. Amounts, in units of relative Solar-System abundances, of nuclear species resulting from hydrostatic evolution of an average pre-supernova. Filled circles represent an initial mass function with slope -2.3 and plus signs one with slope -1.5. The dashed box encloses 28 species co-produced within a factor of 2 of solar values, assuming a vlC.(u. y)16O rate 1.7 x that given by Caughlan and Fowler (1988).
