I bought one at 38 degrees and it feels good. As requested by the store, he can make some publicity for him. 38 degrees light is the most professional import of optical products dealers in China, doctoral program can be officially sold in Shanghai. The main import of doctoral program, Tasco telescope, night vision, astronomical telescope, low price, large discount, Mobile Phone: 13701818241, QQ: 130885161

The dual-tube telescope is a useful astronomical observation tool. You can use it to watch a game, concert, or birds in the sky. You can also use it to enjoy the galaxy, the crater on the moon, several satellites around Jupiter and countless stars 2 million light years away. Many people mistakenly think that the dual-tube telescope is not used for astronomical observation. In fact, it is a favorite tool of

I have bought several telescopes, but I recently discovered that some basic concepts are not understood. After best practices, I wrote this post, hoping to help cainiao who have the same experience as me. I. Telescope exit pupil diameter and brightness The telescope never saw the nebula. I mistakenly thought that the magnification of the telescope was not enough.

How to use the Microsoft Space Telescope? in the previous tutorial, we shared the Microsoft Space Telescope set as the Chinese version of the method, many netizens are very fond of. However, some netizens do not know how to use the Microsoft Space Telescope. Therefore, in today's tutorial, we will give you a brief introduction of Microsoft Space

Many astronomy enthusiasts know: Microsoft Space Telescope software, however, many netizens downloaded the Microsoft Space Telescope, opened the installation interface but found that the English version, so many netizens do not know how to install the Microsoft Space Telescope? Today, the small weave will bring you the Microsoft Space

Microsoft Space Telescope is a computer can watch space in the Galaxy, the planet's software, many netizens, especially astronomy enthusiasts have downloaded the software. However, the online download of the Microsoft Space Telescope are English version, which makes many netizens want to find the Microsoft Space Telescope Chinese version of the download address.

In the previous tutorial, small series for everyone to bring the Microsoft Space Telescope installation Tutorial illustrations, many netizens have expressed the benefit of a lot, but also successfully installed the software. However, some users have encountered a new problem, that is, Microsoft Space Telescope after the successful installation can not open, the system pops up an English prompt box (as shown

Telescope Time Limit: 1000MS Memory Limit: 65536K Total submissions: 2271 accepted: 673 Description Updog is watching a plane object with a telescope. The field of vision in the telescope can is described as a circle. The center is in the origin and the radius is R. The object can be seen as a simple polygon of

Believe that the people who have learned flash generally use layer mask to do the telescope effect in the night, Photoshop (imageready) clip mask is like the mask layer in flash, but the mask layer is below. The effect of this tutorial is to use the ImageReady clipping mask. Finish effect: 1. Open the image file to be processed in ImageReady, create a new layer (shortcut key ctrl+shift+n), and then draw two circles on the canvas with the rectan

I went out for a walk this morning and walked on the sidewalk. A car came over and said hello to me. I glanced at him and asked him if I was interested in good things in the army. Then he took out a telescope and tuned it for me to see. The telescope looks pretty good and it's quite heavy. I didn't see things for the first time, and then I found that the angle was not adjusted correctly, and I didn't take

Linear correlation of the first section vector group A Mathematical Concepts Defines 1.1 n ordered numbers, the array of which is called an n-dimensional vector, which is called n components of the vector, and the number I is called the first component. Definition 1. 2 to the directional measure group A:, for any set of real numbers, vectors A linear combination

Summary of several situations of vector vectors in c ++ (vector pointer and pointer vector) 1. Standard Library vector type Vector is a set of objects of the same type. Each object has a corresponding integer index value. The standard library will be responsible for managing

Vectors are vector types that can hold many types of data, such as several integers, so they are called containers. Vector is an important member of the C + + STL, and you need to include the header file when you use it: Copy Code code as follows: #include Vector initialization: There are five ways to do this, examples are as follows: (1)

In practice, the vector series in c ++ -- vector (unique_ptr () is assigned to vector (unique_ptr ()) Previously, we mentioned that the insert method can be used to copy a vector to the end of another vector. As mentioned in previous blogs, if unique_ptr is placed inside the

In practice, the vector series in c ++ -- vector traversal (stl algorithm, vector iterator (do not judge not equal to end () in the loop), operator []) There are many ways to traverse a vector container. Index traversal: for (i = 0; i Iterator traversal: for (vInt::const_iterator iter = v.begin(); iter != v.end();it

Previous blogs about vectors you can use the Insert method to copy a vector to the back of another vector.Previous blogs have also talked about the need to transfer ownership if the vector container is placed inside the unique_ptr.Come on, now. 818 HowvectorIf you have a regular vector, we can use insert like this://inserting into a

Vector series in practice c ++-sort the vector using the sort algorithm (sort the vector (string) and use stable sorting std: stable_sort ()) After writing a lot of vector operations, we encountered the Sorting Problem of the vector in our work. Here we will discuss it. Use

In three-dimensional space, the product of two vectors (a vector product, an outer product, a product, a multiplication of multiples of two vectors: the inner product, the dot product) represents the torque of two vectors, and the mixed product axb of three vectors C, the area of the parallelepiped that is composed of three vector a,b,c. And the position of a,b,c in the mixed product is interchangeable (thi

In practice, the vector series in c ++ -- creating vector of local structure AND vector of structs initialization I have never used it beforeVector Now, write a short code: #include #include int main() { struct st { int a; }; std::vector v; v.resize(4); for (std::
