1. How many account addresses can an Ethereum node have at most
A: generally, there is only one account address, otherwise there will be an error! blockchain itself is unique. If there are multiple account addresses on one node, it violates the fundamental principle of blockchain!

2. The performance of R9 370x and R9 370 is about 20% to 25% better than that of R9 370x. The performance of R9 370x is 370.2g and 370x.4g, which is superior to that of R9 370x in eating video games. In addition, the performance of R9 370x is also better than that of R9 370,
3. No this graphics card, you must have the wrong number, amd did not release this graphics card
4. Sapphire is the best
5. R9 370 needs al card to use 4G video memory
otherwise, buy 2G. Because 4G can't be used, its performance can't keep up with video memory
the performance of R9 370 is about the same as that of the previous n-card gtx660ti. Certainly not as good as the current gtx960

6. You should be talking about "Morgan Silver Coin and Dutch Keaton silver coin". This is a kind of commemorative coin. It can be regarded as a collection, not a virtual currency. It has nothing to do with virtual currency
if someone publicizes such counterfeit money, it may be a pyramid scheme. Virtual currency pyramid schemes are very rampant. bitcoin has gained a high reputation since 2013. Some criminals have carried out pyramid schemes under the guise of bitcoin. Bitcoin home has exposed spark entertainment, bitcoin pyramid schemes and portcoin schemes.

7. 1、 How much is it?
1. Teaching content:
how much is it?
is an experimental textbook of compulsory ecation curriculum standard published by Beijing Normal University—— P20
2. Brief analysis of teaching materials:
How heavy is learned on the basis of students' mastering the knowledge of weight, and it is also the first time for students to systematically contact with quality units, so as to lay a good foundation for further learning other quality units in the future< There are four parts in the textbook. Through the teaching situation of "how much is there", students can perceive the lightness and heaviness of objects, and the weight of objects can be expressed in kilogram and gram; And through the operation activities such as weighing, estimating and weighing, the students can feel and understand the unit of mass kilogram and gram, as well as the relationship between them. Finally, consolidate what you have learned through practice. On the basis of the original teaching materials, I have dealt with the teaching materials flexibly, with activities throughout the whole class. Let every student have the opportunity to practice and enjoy the joy of success
3. Teaching objective
knowledge objective: to feel and understand the mass unit of kilogram and gram, understand the actual mass of 1kg and 1g, and master 1kg = 1000g< The goal of intelligence is to cultivate students' abilities of observation, analysis, generalization, operation and innovation. It can make simple conversion and estimation
emotional goal: to be able to actively explore and discover mathematical problems, experience the close relationship between mathematics and life, obtain positive mathematics learning emotion, and infiltrate patriotic ecation at the same time
4. Key points and difficulties of Teaching
key points: feel and understand the weight unit of kilogram and gram, and master "1kg = 1000g"
difficulty: understand the actual mass of 1kg and 1g< (1) four students were in a group, and prepared for each group: a scale, two pennies, one bag of 1kg sugar, two bags of 500g salt, one bag of 500g, 800g and 2kg sand, one bag of apple and one bag of... Egg
(2) small survey: understand the quality of life items and their weight, and record< Second, teaching method and learning method
new classroom teaching is no longer a stage for teachers alone, but a stage for interaction between teachers and students. Teachers are just organizers, guides and collaborators of mathematics learning. In teaching, I just create situations for students, provide conditions for discovering knowledge, and guide them to explore knowledge actively, master knowledge and develop ability
2. Focus on students' participation and promote students' application of mathematical knowledge
classroom teaching is the cradle of implementing innovative ecation and cultivating students' healthy growth. Therefore, it is very important to create a harmonious and democratic learning environment, give full play to students' subjective participation, and guide students to actively acquire knowledge. In teaching, I completely give the initiative to the students, so that students can learn new knowledge independently in a series of practical activities such as weighing, comparing, estimating, calculating and weighing< Third, the process of Teaching
1< On October 24, 2007, the lunar exploration satellite Chang'e-1 was successfully launched at China's Xichang launch center“ The takeoff weight of Chang'e-1 is 2350kg.)
introce the take-off weight of Chang'e-1, derive and write on the blackboard topic: how heavy is it
through this introction, students can feel that mathematics comes from life and is applied to life. And the kilogram and gram of these two quality units have a preliminary understanding, while stimulating the patriotic enthusiasm and pride of students
2. Operating experience and exploring new knowledge
the first step: feel 1kg
activity 1: feel 1kg
math games are heavier than 1kg
the second step: feel 1g
activity 2: feel 1 gram
activity 3: look for items that weigh 1G in your life
activity 4: compare the weight of 1 kg and 1 g
the third link: the relationship between "kg" and "g"
(Courseware: naughty and Xiaoxiao are arguing about the weight of two bags of 500g salt or one bag of 1kg sugar.) By weighing and calculating, it can be concluded that 1kg = 1000g
exercise:
2kg = () g4000g = () kg
7kg = () g8000g = () kg
3. Practical application, deepen understanding
activity 5: weigh an apple
activity 6: estimate and weigh how many eggs... The weight of eggs is about 1kg
activity 7: guess and recite the weight of a table mate
4. Summarize the whole course and expand the application
(1) design "do you know?" My extracurricular knowledge< The recommendation of the World Health Organization is that the daily amount of salt for the general population should be 6-8g. The dietary guidelines for Chinese residents advocate that the amount of salt should be less than 6 grams per person per day
there are about 50 grains of 1 gram of rice. If each person wastes 1 grain of rice every day, the whole class of 55 people will waste about 1 gram of rice every day; The city's 3.7 million people waste about 74 kg a day; The country's 1.3 billion people waste 26000 kg (26 tons) in a day.)
students' understanding of "kilogram" and "gram" of quality units can be further improved by using intuitive pictures, and health ecation and ideological ecation of food saving can be infiltrated at the same time. So that the goal of classroom teaching can be achieved
(2) at the end of the class, what I give students is not a full stop, but an ellipsis. I designed such a small story as the after class thinking problem of this lesson
(Courseware: Pig and smart dog go to Huahu beverage house to have a drink. Piggy accidentally broke Huahu's glass. Flower fox want to knock piggy a pen, want piggy accompany 100 glasses. In the face of broken glass, no one can tell how many glasses have been broken.)
by solving the problem of this little story, students will be trained to use what they have learned to solve practical problems< (4) on learning evaluation“ There is a deep-rooted need in people's psychology, that is, to be a discoverer, researcher and explorer. In children's spiritual world, this need is particularly strong. " Therefore, evaluation is very important. It can make students have a kind of "successful learning" emotional experience, so that students can learn more actively. Therefore, in this lesson, I use the diversity of self-evaluation, mutual evaluation and teacher evaluation to investigate students' learning situation, so that students can learn to evaluate others, evaluate themselves and build self-confidence
