美国数学竞赛mathcount技巧 中英对照
1. Read each problem carefully and multiple timesI cannot stress this point enough. This is the single most important part of MATHCOUNTS for a great number of students, myself included. Misreading the problem is likely one of the leading causes, if not the leading cause, of incorrect answers. Personally, I would have made Nationals in 7th grade had I read some key words correct ("smallest" instead of "largest", "first" instead of "last", etc.). I also would likely have made National CD had I managed to read "Positive" on the final Target question.2. Manage your timeThis falls second on the list of importance, just below misreading. Note that poor time management will likely hamper your ability to read carefully (and multiple times), which will likely lead to even more time wasted. Know when to "give up" on a problem in favor of easier questions. They're all worth the same.3. Do all the questionsDifficulty is extremely difficult to gauge (heh) in general, but even more so when the problems are all roughly the same difficulty level. Don't be intimidated by the question number - many times a #26 will be a giveaway question, while #14 will be one of the more difficult problems. You should aim to at least read through all of the questions (carefully!) and to make a serious attempt on most of them.4. Organize your workIn MATHCOUNTS, you will likely spend a lot of time checking your answers, something that will be much harder to do if your paper is messy and disorganized. The method that you choose will be up to you, but my recommended method is to either section off your paper before the test begins, or to section off your paper as you complete problems. Write down all non-trivial steps - you'll use these for reference. You should include computation, either to the side or in the problem, as this is where you'll do most of your checking.5. Do problems multiple waysMost problems will have several valid approaches to the answer. In most cases, one approach will immediately jump out to you, and you will follow it to the answer. A great way to check your answer is to do the problem in another way, even if it's just slightly different. For example, if you do 5(3+5) as 5*3+5*5 and 5*8, you'll be significantly less likely to make a computation error. Similarly, if use similar triangles and Power of a Point, getting the same answer, you can bereasonably sure your answer is correct (but if they're different, time to find out why!). When using a second method, you shouldn't know what answer you're trying to achieve - you may consciously or subconsciously force yourself to get that answer.6. Make assumptionsThis is a very dangerous, but potentially rewarding technique. Mostly used for time-saving (and especially in CD), what looks like it's true usually is. Rely on your intuition - it's usually a very powerful tool. A combination of practice and experience gives you an intuition that can easily outweigh the time needed for a rigorous solution. This isn't to say guess; rather to make educated guesses.For example, take 2011 Chapter Target #8. From experience, I was able to immediately guess that the b in was 2 ( is highly associated with 45-degree angles and squares), which immediately led to (there's no other possible answer that makes it between 0 and 1). This gives the correct answer of 3 without any effort, on a relatively difficult problem (for chapter).Disclaimer: Only use this technique when necessary. If you have time, focus on checking problems you used this method on FIRST, before checking others.7. Don't check in orderIt's usually a waste of time to check from #1 to #30 in that order. You'll end up using your precious time checking problems that are almost certainly correct instead of checking those that need it. Make a mark on your paper next to the question number signifying that you are unsure of your answer. Make a seperate mark if you arrived at the answer without a rigorous solution (see tip 6). Focus on checking these first. After that, focus on checking problems that you aren't 100% sure of, then go to the easier problems. I also made notes of problems that were essentially just computation, because I always made computational errors on early problems. You may decide that you need marks for certain issues that you typically encounter, which is also fine.8. CD - Buzz in before you know the answerAnother dangerous but rewarding technique, only do so if you know you can get the answer within 3 seconds. For example, if you know that the answer is 15*16, that would be a good time to buzz in. Countdown is also an important time to utilize tip 6 - use your intution! With only 45 second per problem, and the "race" element, you need to be very fast in order to pick up your points. For example, this question: If , compute n, from the 2011 State CDround, was one that I instantly recognized as a question I could solve within 3 seconds (btw, so did my opponent). I instantly buzzed in (before I knew the answer!), gave the correct answer of 5, and ended up winning my next match to make Nationals. Had I not buzzed in when I did, my opponent would have (he was going for his buzzer as well), and I would have missed out. In this case, the extra few milliseconds were incredibly important.9. Take it easyFinally, don't dwell on your results, good or bad, however cliche that sounds. Poor results do not really indicate much in a competition like MATHCOUNTS, where the difference between a national winner and a person just missing out on State CD is generally very small. It comes down to tiny speed tricks that makes one person just a little bit faster than the other guy, which can be enough. I know it won't feel like it at the time, but you're the lucky ones. As middle schoolers, you have so much time left to improve, both math-wise and competition-wise (yes, they can be seperate things). If you get 11th written at State (which I did in 7th grade), or 5th CD (which my friend did last year at States [because I beat him]), you'll be originally crushed, but in the end, it really makes so little difference. Both me and my friend do decently at math now, despite our... failures at MATHCOUNTS. There's a lot more to life than it.第1条：仔细、多次读题这点再怎么强调也不过分这是MATHCOUNTS最重要的一条技巧，不仅对学生，也包括我自己。

Countdown倒数-Victoria Justice英文歌词
Intro:
Yeah, yeah, yeah
ohohohoh, yeah
Chorus:
All my attention baby
My extra time
There's nothin' I won't give you
Girl if you were mine
I'ts a countdown fallin' faster 2x
Don't think I'm gon' last now
[Oh, Oh] Wait a minute
I said wait a minute, wait a minute [Oh, Oh]
Don't you know that I want you 2
You're the one [Yeah]
Refrain:
It's a countdown to your loone girl
I'ts a countdown fallin' faster 2x
Six million times I'm thinkin'
About your face
You know I'm crazy for you
Let me count the ways
Too many girls I'm chasin'
I've had my fun
But all the time was wasted
[Oh, Oh] Wait a minute

美国数学竞赛mathcount技巧 中英对照
1. Read each problem carefully and multiple timesI cannot stress this point enough. This is the single most important part of MATHCOUNTS for a great number of students, myself included. Misreading the problem is likely one of the leading causes, if not the leading cause, of incorrect answers. Personally, I would have made Nationals in 7th grade had I read some key words correct ("smallest" instead of "largest", "first" instead of "last", etc.). I also would likely have made National CD had I managed to read "Positive" on the final Target question.2. Manage your timeThis falls second on the list of importance, just below misreading. Note that poor time management will likely hamper your ability to read carefully (and multiple times), which will likely lead to even more time wasted. Know when to "give up" on a problem in favor of easier questions. They're all worth the same.3. Do all the questionsDifficulty is extremely difficult to gauge (heh) in general, but even more so when the problems are all roughly the same difficulty level. Don't be intimidated by the question number - many times a #26 will be a giveaway question, while #14 will be one of the more difficult problems. You should aim to at least read through all of the questions (carefully!) and to make a serious attempt on most of them.4. Organize your workIn MATHCOUNTS, you will likely spend a lot of time checking your answers, something that will be much harder to do if your paper is messy and disorganized. The method that you choose will be up to you, but my recommended method is to either section off your paper before the test begins, or to section off your paper as you complete problems. Write down all non-trivial steps - you'll use these for reference. You should include computation, either to the side or in the problem, as this is where you'll do most of your checking.5. Do problems multiple waysMost problems will have several valid approaches to the answer. In most cases, one approach will immediately jump out to you, and you will follow it to the answer. A great way to check your answer is to do the problem in another way, even if it's just slightly different. For example, if you do 5(3+5) as 5*3+5*5 and 5*8, you'll be significantly less likely to make a computation error. Similarly, if use similar triangles and Power of a Point, getting the same answer, you can bereasonably sure your answer is correct (but if they're different, time to find out why!). When using a second method, you shouldn't know what answer you're trying to achieve - you may consciously or subconsciously force yourself to get that answer.6. Make assumptionsThis is a very dangerous, but potentially rewarding technique. Mostly used for time-saving (and especially in CD), what looks like it's true usually is. Rely on your intuition - it's usually a very powerful tool. A combination of practice and experience gives you an intuition that can easily outweigh the time needed for a rigorous solution. This isn't to say guess; rather to make educated guesses.For example, take 2011 Chapter Target #8. From experience, I was able to immediately guess that the b in was 2 ( is highly associated with 45-degree angles and squares), which immediately led to (there's no other possible answer that makes it between 0 and 1). This gives the correct answer of 3 without any effort, on a relatively difficult problem (for chapter).Disclaimer: Only use this technique when necessary. If you have time, focus on checking problems you used this method on FIRST, before checking others.7. Don't check in orderIt's usually a waste of time to check from #1 to #30 in that order. You'll end up using your precious time checking problems that are almost certainly correct instead of checking those that need it. Make a mark on your paper next to the question number signifying that you are unsure of your answer. Make a seperate mark if you arrived at the answer without a rigorous solution (see tip 6). Focus on checking these first. After that, focus on checking problems that you aren't 100% sure of, then go to the easier problems. I also made notes of problems that were essentially just computation, because I always made computational errors on early problems. You may decide that you need marks for certain issues that you typically encounter, which is also fine.8. CD - Buzz in before you know the answerAnother dangerous but rewarding technique, only do so if you know you can get the answer within 3 seconds. For example, if you know that the answer is 15*16, that would be a good time to buzz in. Countdown is also an important time to utilize tip 6 - use your intution! With only 45 second per problem, and the "race" element, you need to be very fast in order to pick up your points. For example, this question: If , compute n, from the 2011 State CDround, was one that I instantly recognized as a question I could solve within 3 seconds (btw, so did my opponent). I instantly buzzed in (before I knew the answer!), gave the correct answer of 5, and ended up winning my next match to make Nationals. Had I not buzzed in when I did, my opponent would have (he was going for his buzzer as well), and I would have missed out. In this case, the extra few milliseconds were incredibly important.9. Take it easyFinally, don't dwell on your results, good or bad, however cliche that sounds. Poor results do not really indicate much in a competition like MATHCOUNTS, where the difference between a national winner and a person just missing out on State CD is generally very small. It comes down to tiny speed tricks that makes one person just a little bit faster than the other guy, which can be enough. I know it won't feel like it at the time, but you're the lucky ones. As middle schoolers, you have so much time left to improve, both math-wise and competition-wise (yes, they can be seperate things). If you get 11th written at State (which I did in 7th grade), or 5th CD (which my friend did last year at States [because I beat him]), you'll be originally crushed, but in the end, it really makes so little difference. Both me and my friend do decently at math now, despite our... failures at MATHCOUNTS. There's a lot more to life than it.第1条：仔细、多次读题这点再怎么强调也不过分这是MATHCOUNTS最重要的一条技巧，不仅对学生，也包括我自己。

countdownlatch 的用法
CountdownLatch的用法1. 简介CountdownLatch（倒计时门闩）是Java中的一个同步工具类，它可以让一个或多个线程等待其他线程完成操作后再继续执行。
CountdownLatch主要用于控制一个或多个线程等待其他线程完成某些操作，然后再继续执行。
CountdownLatch内部维护了一个计数器，该计数器初始化时可以指定一个初始值，当计数器减到0时，所有等待的线程将被唤醒。
CountdownLatch的主要方法有两个：countDown()和await()。
countDown()方法用于将计数器减1，await()方法用于等待计数器减到0。
2. 使用场景CountdownLatch的使用场景通常是当一个任务需要等待多个子任务完成后才能继续执行的情况。
例如，一个主线程需要等待多个子线程全部执行完毕后再进行某些操作，这时可以使用CountdownLatch来实现线程之间的同步。
3. 示例代码下面是一个使用CountdownLatch的示例代码：import java.util.concurrent.CountDownLatch;public class CountdownLatchExample {public static void main(String[] args) throws InterruptedException {int threadCount = 5;CountDownLatch latch = new CountDownLatch(threadCount);for (int i = 0; i < threadCount; i++) {Thread thread = new Thread(new Worker(latch));thread.start();}latch.await();System.out.println("All workers have finished their tasks.");}static class Worker implements Runnable {private final CountDownLatch latch;public Worker(CountDownLatch latch) {tch = latch;}@Overridepublic void run() {try {// 模拟执行任务Thread.sleep(1000);System.out.println("Worker finished task.");} catch (InterruptedException e) {e.printStackTrace();} finally {latch.countDown();}}}}上述示例代码中，首先创建了一个CountdownLatch对象，并指定了初始计数器的值为5。

SIGMA各款码表中文说明书
SIGMA各款码表中文说明书SIGMA BC506的中文说明书BC506型自行车码表在我们车友中有一定的数量，但由于其说明书是全外文，阅读中难免有些困难，影响码表功能的正确实现，现在我结合自己的使用经验对该型表的使用做一简单介绍，希望能对大家提供帮助.SIGMA BC506型自行车码表使用说明功能介绍1、可显示速度、骑行距离(最大99，999KM)、骑行时间(最大999:59小时)、累计骑行里程(最大99，999KM)，时钟功能.2、手动和自动显示功能。
自动显示(AUTO),自动显示功能开启后，能间隔1秒，顺序显示骑行距离、时间、总里程和时钟。
下面简单介绍一下使用方法:一、功能显示。
1、自动显示。
按动功能按钮(码表下方大按钮)，只至出现AUTO字样，此时码表自动显示骑行距离、时间、总里程和时钟，间隔时间为1秒。
2、手动显示。
按动功能按钮，出现KM字样，表示此时显示的是旅行距离;按动功能按钮，出现闹钟图案，表示此时显示的是旅行时间，精确显示到秒;按动功能按钮，出现Σ字样，表示此时显示的是从装上码表开始的累计骑行距离。
3、码表清零。
按住功能按钮不小于3秒，此时码表上的数字闪烁，继续按住不动直到清零，清零不影响累计骑行距离。
二、设定。
此功能决定着码表的正确使用，非常关键。
主要功能是输入车轮周长，调校时钟、改变速度单位、开启自动显示功能等。
进入设置界面。
按住码表背面的设置按钮3秒，出现SET字样，即进入设置界面，此时下面显示的四位数字为车轮周长，此时按动功能按钮，将进入下一个功能的设置界面。
下面以设置车轮周长为例，介绍此功能的使用。
在设置界面下，按动设置按钮，码表上的数字将开始闪动，表示此时可以输入数字，按动功能按钮，闪动的数字会改变，我的车胎是32-630，应在第一个数字位输入2，等待第二个数字闪动，按动功能按钮，第二位输入1，依次在第三位和第四位输入9，即周长为2199。
按照以上的方法，可以调校时钟等，因方法一样不再重复。
