Description: 十年前，微软帝国的缔造者比尔-盖茨(Bill Gates)曾撰写过一本在当时轰动一时的书——《未来之路》，他在这本276页的书中预测了微软乃至整个科技产业未来的走势。盖茨在书中写道：“虽然现在看来这些预测不太可能实现，甚至有些荒谬，但是我保证这是本严肃的书，而决不是戏言。十年后我的观点将会得到证实。”一转眼十年过去了，现在让我们回顾一下盖茨的书中到底预测了些什么，又有哪些已经成为了现实。
-decade ago, Microsoft empire founder Bill- Gates (Bill Gates) has written off a highly publicized at the time the book-- "future", in this book the 276 predicted by Microsoft and the entire technology industry in the next trend. Gates wrote in the book : "Although it appears that these forecasts are not likely to achieve, or even absurd, But I guarantee this is the serious, and not frivolously. Ten years later my point of view will be confirmed. "After a decade has passed, Now let us look at the book Gates predicted in the end what and which has become a reality.

Description: 利用实验箱上的键1—7作为按键，其中键7为复位，键1为1路抢答键，键2为2路抢答键，等等。
按复位后系统响“嘀…..”一短声，6路抢答键起作用，任一抢答键按下时，显示其键号，并封锁所有抢答键，十秒钟后响“嘀…..”一长声，直到按复位键后才能解除声响。
具有抢答开始后20S倒计时，20S后倒计时后无人抢答显示超时的功能，并报警。
能显示超前抢答号并显示犯规警报，某一路犯规抢答，则自动取消（也就是禁止）下一次抢答的权利（1次）。-Experimental use of the key box as a key 1-7, 7 of which reset button, key 1 of 1 way Answer key, 2 key Answer key for 2-way, and so on. Ring after the system reset by " 嘀... .." a short sound, 6 Road Answer key role, either press the Answer button, the display of its key number, and block all the Answer key ring for 10 seconds, " 嘀.... . " a long sound until the reset button by the sound in order to disarm. 20S has a countdown to the start Answer, 20S No Answer after the countdown show, after the function of overtime, and the police.

Description: 聆听有思想的声音，让我们打开不一样的世界；站在巨人的肩上，
让我们看到不一样的天地；让我们时刻铭记，在代码的征途中，不只
有你我在奋斗，还有他们；让我们时刻提醒，在人生的道路上，不只
有你我在努力，还有他们；让我们怀着一颗感恩的心，去感悟他们走
过的岁月，去品读字句中的艰辛，去学习他们高尚的品格，去传递无
私的奉献。没有他们，我们可能要走的艰难。因为他们，我们不在孤
单。感谢他们，照亮我们前方的路。
-Listen to the sound thought, let' s open the world standing on the shoulders of giants, we see a different world let us always bear in mind that, in the code of the journey, not only you and me in the struggle, as well as them Let us remind, on the road of life, not only you in my efforts, but their let us with a grateful heart, to sentiment them through the years, to go and read the words in hardships, go to learn from their lofty character, to pass selfless dedication. Without them, we may have to go hard. Because of them, we are not alone. Thank them, to illuminate the road ahead us.

Description: 能源是人类赖以生存和发展的基础，是经济社会可持续发展的重要物质基础。近两年，能源约束矛盾日益突出。 节能是个老话题，今天，节能并没有成为历史，高速前进的国民经济和走可持续发展之路的国家战略，为节能赋予了新的时代内涵，增添了新的历史使命。
当前，煤、电、油、运全面紧张，价格大幅度上涨，石油对外依存度不断提高，能源供应紧张已经成为经济社会发展的重要制约因素之一。严峻的形势再次提醒我们，保证能源供给依然是未来中国必须面对的最复杂难题之一。节能是推动经济社会可持续发展的必然选择。
在目前电力能源紧张的严峻形势面前，本方案的关键是节约能源，提高路灯管理水平，“在保证照明效果下节电”。在确保灯光系统功能的正常发挥的前提下，通过提高终端用电效率和优化用电方式，在完成同样用电功能的同时减少电量消耗和电力需求，达到节约能源和保护环境，实现低成本电力服务。
-Energy is the basis of human survival and development, is an important material foundation for sustainable economic and social development. In the past two years, energy constraints have become increasingly prominent. Energy conservation is an old topic, today, energy-saving and did not become a thing of the past, to speed ahead of the national economy and take the road of sustainable development of national strategies for energy conservation gives new meaning to add a new historical mission.
, Coal, electricity, oil and transportation are fully tight, prices have increased substantially, continuously improve the dependence on foreign oil, energy supply has become one of the constraints of the economic and social development. The grim situation reminds us once again, to ensure energy supply is still the future of China must face one of the most complex problems. Energy conservation is to promote sustainable economic and social development of the inevitable choice.

Description: 有两条道路双向两个车道，即每条路每个方向只有一个车道，两条道路十字交叉。假设车辆只能向前直行，而不允许转弯和后退。如果有4辆车几乎同时到达这个十字路口，如图（a）所示；相互交叉地停下来，如图（b），此时4辆车都将不能继续向前，这是一个典型的死锁问题。从操作系统原理的资源分配观点，如果4辆车都想驶过十字路口，那么对资源的要求如下：
向北行驶的车1需要象限a和b；
向西行驶的车2需要象限b和c；
向南行驶的车3需要象限c和d；
向东行驶的车4需要象限d和a。
clipboard.png(There are two roads with two lanes, one lane in each direction of each road and two roads intersecting. Suppose that the vehicle can only go straight ahead without allowing for turning and backing. If four vehicles arrive at the intersection almost simultaneously, as shown in Figure (a), and stop at each other's crossroads, as shown in Figure (b), then all four vehicles will not be able to move forward, which is a typical deadlock problem. From the point of view of resource allocation based on operating system principle, if all four vehicles want to cross the intersection, the resource requirements are as follows:
The car that goes north needs 1 quadrants A and B.
Westward driving vehicle 2 requires quadrant B and C.
Car 3 to the South needs quadrant C and D.
4 of the cars to the East need quadrant D and a.
