1. 1. If there are multiple cubes in your cube, then follow the mouse model, use ray on the model, and the cube touched by ray changes (such as color darkening)
2. Draw multiple cubes, arrange them in order, name them, and remove the meshender attribute (no rendering), which is equivalent to drawing a grid, which is easy to understand
3. It's troublesome to judge the range with two-dimensional array (mainly integer), The simple way is that the computer obtains the original coordinates of the model (such as the center point of the model). When the absolute value of the x value (and y value) of the mouse's real-time coordinates minus the original coordinates is equal to the side length of the square, the square (or other dry points) will be displayed with the real-time coordinates as the center, The real-time coordinates are used as the original coordinates for the next step

2. Aprotic solvent is also called aprotic transfer solvent. The proton self delivery reaction of this kind of solvent is very weak or has no self delivery tendency. According to their interaction with solute, they can be divided into dipolar aprotic solvent and inert solvent. This kind of solvent can be divided into: aprotic nonpolar solvent, such as benzene, ether, carbon tetrachloride, etc; Aprotic polar solvents, such as dimethyl sulfoxide, N, N-dimethylformamide, acetone and so on, because the molecules of aprotic polar solvents have polarity, they will affect solute molecules and proce solvation effect. Protonic solvent contains - Oh, - NH, such as methanol, which will form hydrogen bond with nucleophilic reagent and make nucleophilic reagent solvable. Aprotic solvent, also known as proton inert solvent, can not give protons in the reaction system can be called aprotic solvent. Aprotic polar solvents, such as acetonitrile (CH3CN), dimethylformamide (DMF), dimethyl sulfoxide (DMSO), hexamethylphosphoryltriamide (HMPA), etc. Aprotic polar solvents can solvate cations, especially metal cations. Protonation gives a hydrogen ion, which is positively charged, making it more electrophilic. O. The coordination of H + on N and other elements can be simply understood as combining with proton, that is, combining with a proton. Generally, the substance has lone pair electrons, so it can combine with a proton through coordination bond. For example, when H2O becomes H3O + NH3 becomes NH4 +, different substances have different protonation ability, and some substances with larger dipole moment often have weak protonation ability

3. "A lot of scripts" may not be the script of the button wizard, right? Is it an offline script? Is it a script for offline plug-ins?

4. If the platform is opened for trading, Dec will become the form of shares, and it can also have the opportunity to trade on the virtual platform. The current 100 Dec may be worth 1 million RBM in the future. It doesn't necessarily depend on the future operation of the platform

5. Staadchina is very good, but it is more difficult to learn

6. This is very complicated. It needs the approval of the government department. Now cryptocurrency trading has been banned at the national level.

There are several reasons:

1. Replacing new devices requires large-scale regression testing, which costs so much that many people can't imagine. Therefore, it's not a big deal for NASA to replace its hardware platform every ten years

is such a CPU, which can adjust the attitude of the aircraft model at least 50 times per second. Some of them are demanding, and can even adjust their attitude up to 300 times per second

9. There are several reasons: 1. Replacing new devices requires large-scale regression testing, which costs so much that many people can't imagine. Therefore, it's nothing to replace a hardware platform like NASA every ten years. 2. The existing computing resources are sufficient, and many key computing require hard real-time, with very small amount of computation and no need for cool interfaces, So there is no need to upgrade. 3. The area occupied by a single transistor of the earlier processor is large enough, so in the cosmic radiation environment, the probability of calculation error caused by interference is low. Take the example of aircraft model. The modern four-axis flight controller is responsible for the balance, navigation, positioning, remote control and receiving of the aircraft. It has a lot in common with the functions of spacecraft. But do you know what CPUs these flight controllers use? The most common is arino's Atmega32. It's 8 bits, 2KB of memory, 32KB of flash (equivalent to hard disk). The highest dominant frequency is 16mhz. This CPU can adjust the attitude of the model aircraft at least 50 times per second. Some of them are demanding, and can even adjust their attitude up to 300 times per second

10. In the second year, students learn the oral arithmetic of two digit addition and subtraction tens and one digit, as well as the written arithmetic of two digit addition and subtraction. Therefore, in the third year, when learning the oral arithmetic of two digit addition and subtraction, it is easy for students to transfer the written arithmetic of two digit addition and subtraction to the oral arithmetic of two digit addition and subtraction according to their existing learning experience. Some teachers think that it doesn't matter what kind of algorithm students use. On the contrary, using the method of written calculation to do oral calculation not only has a high calculation accuracy, but also won't have a negative impact on students' future written calculation of multiple digits plus or minus multiple digits. This kind of teaching ignores the study of mathematical thinking methods and only pays attention to the teaching of calculation results, which will only formalize the teaching. Students only play the role of a receiver, and they will easily forget it when not in use. Mathematician Polya thinks: teachers should spend one third of their efforts on teaching basic mathematics, and two thirds of their efforts on cultivating students' useful thinking methods and habits. It can be seen from this sentence that he attaches great importance to mathematical thinking methods and thinking habits. In a sense, mathematical thinking method is more important than mathematical knowledge, it has a very important impact on human development. Therefore, how can we infiltrate mathematical thinking methods in our daily teaching, especially in the calculation teaching, which accounts for such a large proportion of teaching tasks? How can our teachers infiltrate mathematical thinking methods in teaching, explore and discover some simple mathematical laws through calculation, and further infiltrate some mathematical thinking methods, so as to make students smarter and more intelligent? It is worth thinking deeply for every math teacher< First, the current situation of calculation teaching in primary school mathematics teaching
textbook factors: the new textbook emphasizes the understanding of calculation theory and the rational use of calculation methods, strengthening the ability of oral calculation and paying attention to the cultivation of estimation consciousness. Especially in the middle and senior grades, we should use the transfer, analogy and transformation of knowledge to guide students to acquire new knowledge. In the textbook, the weight of the calculation problem is not too much, and the difficulty of the calculation problem is much simpler than that of the old textbook
teachers' factors: quite a lot of teachers fail to establish modern teaching concepts and still use the old methods. They only use simple and unchanging teaching methods to put the calculation problems in front of the students. In this way, the students feel that they have no feelings, are not beautiful, are not vivid, cold and rigid numbers, and the students can't feel the pleasure of learning. In teaching, it can't resonate with teachers. Teachers, in order to improve teaching performance, pay too much attention to the acquisition and proficiency of computational skills, so that students passively and uninteresting accept students as a tool of calculus
student factor: primary school students are unwilling to calculate, and secondary school students' geometry learning difficulties are mainly reflected in the following aspects: they feel that the calculation problem is too boring. I don't feel the pleasure and achievement brought by mathematical calculation. Less contact with life, less hands-on. The spirit of hard work is insufficient. Learning to calculate, and some students are just afraid of hardship, afraid of brain, of course, is not good at calculating. Other aspects of knowledge can not keep up, including language knowledge, life experience, etc., so the ability to understand the calculation problem, the ability to express the solution and so on are still lacking. Not good at connecting with the real life around to enrich the imagination.
