Debug (1) 40-6 line priority encoder, the absence of detailed reading of the priority encoder truth table, I consider a priority encoder for low priority coding standards (designed to take trumpet) does not meet the standard. But after an error is found, the hardware circuit without modification, as long as the modified coding standards for the collection of large, we can solve the problem. By amplification of the response signal of the photocell, coding, microcontroller port P1 is reached, a certain delay, the SCM accurate and effective data collection through an external interrupt, you should know the approximate range of the delay. The preparation of the SCM process, write a subroutine in a delay of 2ms, and can call for a certain delay. It is due to the good purchase of 100mw green laser pointer.
Such as wavelength, pulse width, energy, doctors were able to selectively treat the lesions occur in the tissue, without affecting the surrounding normal tissue.

Fundamentally, the human energy of inertial confinement fusion laser drive from the nuclear fusion reaction, which happened on the sun "light fusion". Humans on Earth to achieve a controlled thermonuclear reaction, that is, the hydrogen bomb. To obtain an inexhaustible supply of new energy, this reaction must be continuously carried out under controlled conditions. There are two ways to achieve controlled nuclear fusion First, the scientists there are two ways to achieve controlled nuclear fusion tokamak open First, the scientists used the the tokamak open magnetic confinement fusion research is another proposed technical route in the early 1750s, another route in the early 20th century in the early 1960s, the exhibition "magnetic confinement fusion research.

Magnetic confinement fusion research. Laser inertial confinement fusion laser inertial confinement fusion. The basic principles of laser inertial confinement fusion ICF (Inertial Confined Fusion ICF): using the powerful pulsed laser beam irradiation of deuterium micro-tritium fuel pellet in an instant high heat and great pressure, dense plasma is highly compressed before it spreads outward jet arising from the recoil of the inward implosion of pellet material is compressed to high density and high temperature required for thermonuclear burning, and to maintain a certain degree of confinement time to complete all of the nuclear fusion reaction, releasing large amounts of fusion energy. However, the conditions required by the fusion reaction is extremely harsh. Cost of Laser Pointers can be reduced to the lowest level.

Figure 19-11 shows the experimentally measured output power and gas pressure curve. Output power with axial magnetic field. Axial magnetic field on the discharge tube in the radial motion of charged particles, the role of a Lorentz force, an increase of the axis near the electron and ion density, help to improve the output power. Experiments show that the axial magnetic field can increase the output power of 1-2 times. Axial magnetic field and make the laser line broadening caused by the output power decrease, so there is a maximum power output of the best magnetic field strength (see Figure 19-12). The best value and the discharge current, pressure, diameter and wavelength. As the electrons and ions tend to reduce the impact of the tube to avoid, reduce electrode sputtering in the discharge tube axis, and thus can improve the device lifetime.  stage lighting systems are in famous in the oversea market for its high quality and performance.
