L Arge angles of incidence the response on the cylinder and the Alderson Phantoms are rather similar, whereas the response on The slab significantly deviates from the one on the Alderson Phantom.This paper describes the value of the individual dosage of the eye crystal in the running usage. It was said that the traditional plate body model was used to calibrate the individual doses of the eye crystals, but recently the cylindrical form was recommended for the fixed value of the eye lens dose.

JSON (JavaScript Object Notation) is a lightweight data interchange format. It is based on a subset of ECMAScript. JSON takes a completely language-independent text format, but also uses a similar idiom to the C language family (c, C + +, C #, Java, JavaScript, Perl, Python, and so on). These features make JSON an ideal data exchange language. Easy to read and write, but also easy to machine parse and generate (typically used to improve network transfer rates).The JSON syntax is a subset of the

There is a binary tree, each point on the tree of the right value, the weights are different, please design an algorithm to calculate the maximum weight of the leaf node to the minimum weight of the leaf node distance. The distance between each edge of the binary tree is 1, and the distance that one node passes through the number of edges to the other node for the two nodes.For the root node of the given binary tree, return the distance you are seeking.importjava.util.arraylist;//importjava.util

The first week of school, has been and all the subjects "confrontation" over one or two times, and imagined not quite the same, especially Java learning! In the first Java class, after listening to the teacher's request, my heart is not very repulsive, before the middle school when I received that kind of teaching methods, but I am very clear, now and before very different.Because the textbook is not enough, two or three people a book, so the Thursday preview really special rush, not to mentio

: C language input with scanf, output with printf. Java input with scanner, output System.out.Chapter Fourth Class and ObjectThe class body contains the instance domain and the method two parts, this method is the same nature as the function in C language. The In-class methods have access to the instance domain, so that secure access to the data is achieved through encapsulation. An object contains three parts: The behavior of an object, the state of an object, the identity of an object, and eac

class name. Each class can have more than one constructor. The constructor can have 0, 1, or more arguments, the constructor does not return a value, and the constructor is always called with the new operation. Mastering the role of the constructor's API can learn to use the new symbol to design and generate a class object code.In the Friday experiment class, the teacher through a series of questions infiltrated a lot of knowledge points, his class i
