Q1:投影仪原理 投影仪原理是什么


1、投影仪成像原理:应透镜物距焦距小于二倍焦距成倒立、放大的的原理制造了投影仪。投影仪先将光线照射到图像显示元件上来产生影像,然后通过镜头进行投影。

2、因为元件本身只能进行单色显示,因此就要利用三枚元件分别生成三色成分,然后再通过棱镜将这三色图像合成为一个图像,最后通过镜头投影到屏幕上。

3、DLP是英文Digital Light Processor 的缩写,译作数字光处理器。DLP以DMD(Digital Micromirror Device)数字微反射器作为光阀成像器件。一个DLP电脑板由模数解码器、内存芯片、一个影象处理器及几个数字信号处理器(DSP)组成,所有文字图象就是经过这块板产生一个数字信号,经过处理,数字信号转到DLP系统的心脏--DMD。

    By comparing these figures, Pew seems to suggest that China and the US are engaging in a popularity contest in the PhilippinesMeanwhile, two-thirds say having a strong economic relationship with China is more important for ties between the two nations, while only 28 percent say being tough with China on territorial disputes is more vitalFully 86 percent have a favorable view of Duterte himself; 78 percent support his handling of the illegal-drugs issue; and 62 percent say that the Philippines government is making progress in its anti-drug campaignThat was certainly not the policy under Obama when he launched the US pivot-to-Asia policy, trying to gang up US allies on China

    And on global economic status, about half of Filipinos (49 percent) say that the US is still the leading economic power, but that is down from 66 percent who said so in 2015But Filipinos also share positive views of China and its leader, President Xi JinpingSince becoming Philippines president in June 2016, Rodrigo Duterte has refused to be used by the US to advance its strategyHowever, the Pew survey finds that Duterte and his policies are widely popular at home despite concerns expressed by some governments, in particular the US, over Duterte's clashes with drug cartels and alleged human rights violations

    In 2014, the Philippines was still led by Aquino IIIThis represents a dramatic shift since that question was last asked in 2015

    It clearly suggests that one's gain is another's lossThe Philippines under Duterte has tried to develop an independent foreign policy rather than being a US puppet most of the time

    The US government, lawmakers and pundits have generally expressed negative views of Duterte since he took office last JuneAnd overall, the perception gap between the US and China in the Philippines is narrowingAccording to the survey, 78 percent in the Philippines have a positive view of the US as of this spring, down from 92 percent who expressed positive sentiments in 2015But the Philippines, and indeed all the countries in the region, should be encouraged to have good relations with both China and the US, a real win-win situation for not just the three countries involved, but for the region and the worldAt the same time, 78 percent believe the current economic situation is good, and 57 percent are satisfied with the direction of the country, a 21 percentage-point increase from 2014, the last time this question was asked in the PhilippinesSome even believe that he would not able to serve the full six-year term

    A zero-sum mentality about China-US relations is reflected not only in the thinking of some US politicians, but also in a new survey conducted by the Pew Research CenterThe report finds that people in the Philippines still like the US and have confidence in its leader, President Donald Trump

    The survey released on Sept 21 bore a title saying people in the Philippines still favor the United States over China, but that the gap is narrowingA quarter now name China as the world's leading economy, up from 14 percent the last time the Philippines was surveyed

    Such an independent policy is dealing a heavy blow to those who still view the relationship between the three countries as zero-sumAnd despite the Philippines being the most pro-Trump nation in Pew's spring 37-country survey, confidence in Trump now is lower than it was in then-President Barack Obama in 2015

    The US was believed to be fully behind the scenes when the Philippines, under President Benigno Aquino III, filed the arbitration suit in 2013 against China in a tribunal in The Hague, a case in which China had refused to participateHis tough rhetoric on the US and softened rhetoric on China, especially compared with his predecessor Aquino III, has worried many in the USThe Obama administration had done everything it could to internationalize the South China Sea issue and had used the Philippines, a US ally, to advance the American strategyThe negotiations may take days or weeks before a deal is struck between the future governing partners

    Winston Peters, the party chief of the New Zealand First Party, however, refused to say which party he would side withAUCKLAND - New Zealand's parliamentary elections on Saturday yield no clear winner as tally ended in the wee hours of Sunday, leaving the third largest party with 7

    The New Zealand First Party has garnered nine seats, making it the indispensable coalition partner for both the National Party and the Labor Party to form the governmentThe ruling National Party has secured 46 percent of the party votes, which transfer to 58 seats in the 120 member Congress in an Mixed-Member Proportional voting system, with the opposition Labor Party lagging behind at 35

    8 percent votes or seven seats in the congress would just make enough seats to form a government if they can successfully get the New Zealand First Party on boardAccording to the Ministry of Education of the Inner Mongolia, the exhibition attracted 39 universities from 16 countries, including Mongolia, Russia, the United States, Britain and South Korea

    It showcased the achievements of Chinese and foreign universities in education exchange, personnel training, and scientific research cooperationTeachers and students of Inner Mongolia Normal University gave performances at the event, including Tai Chi, flute playing, and Mongolian songs and dances, which have won generous applauseThe China-Mongolia Education and Technology Exhibition was held in Hohhot, Inner Mongolia autonomous region on Sept 26, when nine cooperation agreements were signed by eighteen Chinese and foreign universitiesThe pandas were born at the Ya'an Bifengxia base, part of the China Conservation and Research Center for the Giant Panda in Sichuan
