After measuring the MTF value curve of each lens, the Hassu lab developed a calculation method for the average value of the MTF. First, the preset focal length is used to calculate the MTF value of the lens F4, multiply by the focusing coefficient of 0.4 and 0.6 respectively to obtain the MTF value of a first-line frequency, and then multiply the average value of the 10-line/millimeter value by the focusing coefficient of 0.57, the average value of th

For example, enter "How IS is", output "you is how";public class Text1 {public void reverse (String str) {string[] Wordsarray = Str.split ("");System.out.print (" reverse word output :");for (int i = wordsarray.length-1; I >= 0; i--) {System.out.print (Wordsarray[i] + "");}}}(2) Writing unit tests for testing;Import static org.junit.assert.*;Import Org.junit.Test;public class Text {@Testpublic void Test () {Text1
We implement it in a virtual machine environment. Generally, when a virtual machine is opened, it will slow down. We only use one 2003 Server for customer service machine verification, during verification, you only need to set the 2003 Nic channel. In this experiment, the Red Hat Enterprise Edition 4 is used. The following describes how to implement the dhcp test in linux.
