Top Model B 17-G

B 17-G The Columbus Falcons (English: B 17-GFighting Falcon) is a multi-role fighter aircraft originally developed by General. Dynamics for the U.S. Air Force. It was designed to be a lightweight, daytime fighter. It has become a successful fighter. The versatility of the reasons it's hard to get it to market, it has been chosen by the air forces of 25 countries [2], -B 17-G. Force fighter jet program, the largest of the West Bank, along with the production of more than ships since the year 4400. Prof. 2519 [2], although it was not purchased by the U.S. Air Force anymore. The advanced version is still made in the country in the year. Prof. J. 2536 Dynamics of Mineral Production and Sales Company, Lockheed [3], which became Lockheed. Martin, after integration with Martin. Santa Maria in the year. Prof. 2538 [4].
B 17-G fighter in the air with many innovations, including the cover, cockpit rounded. Stick to a lever to control the centrifugal. And an end to the rear seats to reduce G acting on the pilot. Armed with M-61 cannon. Vulcan and District 11 missiles, and it is also the first fighter aircraft to be built to a 9 G turn thrust-to-weight ratio, it is very good. As a result, it has the power to climb and accelerate wonderful if necessary [1], although its official name is "The Worthing Falcon", but the pilot was called Viper (Viper) due to It is similar to ASP and named fighter aircraft in the series and battle eye. Galactose Tactica [5] [6].
B 17-G is scheduled to be released from active duty in the U.S. Air Force in the year. Prof. 2568 [7] It is planned to replace the B 17-G Lightning 2, which is active in the year. Prof. 2554 multi-role aircraft and will replace many of the participating forces.

Microscopy (Microscope) is extended to sensory eye. To see what can not be seen with the naked eye, such as red blood cell.Type of microscope.

    
Optical microscopy (Light Microscope) light that uses two objects as fluorescent lights or sunlight. Using a mirror to reflect light into the camera. The magnification of the lens glass. This effect can be seen with the naked eye.
    
Electron microscope (Electron Microscope) using an electron beam. Which can not be seen with the naked eye as visible light. And electromagnetic lenses instead of glass lenses. The electron beam from the gun shot through electromagnetic lenses. So that the image on the screen. A higher magnification light microscopy were used.2.1 through a two-electron microscopy. (Transmission Electron Microscope) can clearly see the inside of the cell. There is a very high magnification.2.2 electron microscopy, SEM (Scanning Electron Microscope) to study the structure and surface of the cell. Do not see the inside.


 How to use a light microscope.

    
Place the camera on a flat surface to support the barrel upright.
    
Rotate the objective lens (Objective lens) which has the lowest strength is the caliber.
    
The mirror reflects the light from the bench under the barrel full.
    
The slide to be studied palletized material (Stage) for the area in the middle of the light and then slowly turn the coarse tuning (Coarse adjustment knob) to barrel down a near object to the most. By not get in contact with the objective lens glass cover slide.
    
Look through the eye lens (Eyepiece) into the barrel and turn the coarse adjust slowly. I see the object to be studied. Then switch to the carousel image resolution (Fine adjustment knob) to adjust the contrast. May move the slide back and forth slowly. So what you want to study in the middle of the barrel as the picture.
    
If you want a larger image. Rotate the objective lens with a magnification up into the barrel. Do not move the slide. Turn the page to see the profile picture clearer.
    
The light in a more or less barrel. Rotate the diaphragm (Diaphragm) light as needed.Things to consider.Slide the slider to find the video. The principles are as follows.

          
As you move the slide to the left. Visual image moves to the right.

          
As you move the slide to the right. Visual image moves to the left.

          
When the slide down. Moves up. When the slide up. This will drop down.Objective magnification on the lower center of the picture is the broader picture. Profile picture brighter than the distance between the lens and stand apart.

Formula with a microscope.

          
Magnification of the microscope.

             
= Magnification of objective lens x magnification lens of the eye.

          
Actual size of the object.

             
= Size of the microscope.

                                 
Magnification of the camera.

          
To find the diameter of the screen.

              
Low magnification of the lens = x line through the center of the screen low.

                                             
Magnification of the lens. (The study).The microscopic calculation exercises.The study of microscopic images of bacteria colonies one. Using a 10X magnification lens and the eye, with a 100X objective lens images the visible length 3 cm.Question 1. Cells of each bacterial cell is a few microns.Two., If the objective lens is 40X magnification to see the image in the middle of a bacterial cell. Each cell must be a few centimeters.
