There is a central island between the two tunnel junctions, its three electrodes are source electrode, drain electrode and grid electrode which used to control electron number of quantum dot.
depends on transmission coefficient of barrier to electron wave and the number of independent electron wave modes.
For current to flow the number of electrons on the droplet must fluctuate between N and N+1.
Its basic structural scheme is shown in Fig. 5, the nanometer crystal grain (quantum dot) is placed in oxidizing layer which is between channel of MOSFET structure and control gate.
When eliminate the dependence on variable, the equation is simplified as: (2) N is the number of electrons in quantum dot, is the total capacitance of quantum dot.

The results demonstrated that the higher average molecular weight was, the higher CO2 concentration was. in seeding period, jointing period, spike formation period, grain forming period and full ripening period.

The crankshaft shown in Figure 1 is a part that our cooperative enterprise meets with in production.It is an important component of the vortex air conditioning compressor,on which it has a spline processing requirement: EXT18z x 0.5 m × 45R x 6 f (number of teeth z = 18, modulus m = 0.5, pressure Angle α = 45 º).
Investigation of work hardening of flat-rolled helical-involute gears through grain-flow analysis, FE-modeling, and strain signature[J].

Different properties show different material number.

The DDA method was proposed in 1973 by Purcell and Pennypacker who used it to study interstellar dust grains, and then it was improved by Draine, Goodma and Flatlau[1-3].
For an particle with equivalent radius aeff , N denotes the number of discrete dipole, thus: (9) Numerical calculation and analysis First, we take the cylindrical nano-graphite particles as examples, using DDA method to analyze the characteristics of infrared extinction.

The formula of calculating the screen box centroid is: (6) In the equation: G i, x i, y i stand for the i-th parts or components of the mass and centroid coordinates;n is the number of components or parts.

A large number of experiments have been conducted to help the sustainability of glass.
The glass powder with grain size in between 40µm to 63µm was mixed with ball clay and feldspars using ratio 90:5:5.

Wood dyeing can remove colour differences between heartwood-sapwood and earlywood-latewood, and make sure that grain, figure and sense of quality become vivid.
Chinese fir, poplar, eucalyptus and rubber wood are divided into 4 groups, and are numbered.
