The new revision of the code and rule , reflects the party39。s eighteen, ten eight plenary, the spirit of the Fourth Plenary Session of the Eleventh Central Committee and General Secretary Xi Jinping important instructions on the revised low political criterion and Regulations , highlighting the ruling party characteristics, serious discipline, the discipline quite in front of the law, based on the current, a longterm, advance as a whole, with Bu Xiuding independent rule and rule . Main principle is: first, adhere to the party constitution to follow. The constitution about discipline and selfdiscipline required specific, awaken the party constitution of party passes party consciousness, maintaining the authority of the constitution. General Secretary Xi Jinping pointed out that no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules. In early 2020 held the eighth session of the Central Commission for Discipline Inspection Fifth Plenary Session of the 16th Central Committee, Xi Jinping again pointed out that constitution is the party must follow the general rules, but also the general rules. the revision of the 22 / 60 code and rule is Method in adhere to the regulations established for the purpose of bining rule of virtue is to adhere to the party constitution as a fundamental to follow, the constitution authority set up, wake up the party constitution and party rules the sense of discipline, the party constitution about discipline and selfdiscipline specific requirements. 4 second is to adhere to in accordance with the regulations governing the party and the party. The Party of rule of virtue de, mainly refers to the party39。s leadership and the party39。s several generation of leaders, especially Xi Jinping, general secretary of the important discussion, refer to the three discipline and eight points for attention statements, and reference some embody the Chinese nation excellent traditional culture essence of epigrams. (2) the revised regulations, the main changes in the revised Regulations to fully adapt to the 26 / 60 strictly requirements, reflects the according to the regulations governing the law of recognition of deepening, the realization of the discipline construction and Jin Ju. rule is party a ruler, members of the basic line and follow. And the majority of Party members and cadres of Party anizations at all levels should adhere to the bottom line of thinking, fear discipline, hold the bottom line, as a preventive measure, to keep the party39。 two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage the 19 / 60 authority of Party Constitution of misconduct lack necessary and serious responsibility to pursue。 the fourth part on how to grasp the implementation of the two regulations of the party. code and Regulations revised the necessity and revised 17 / 60 history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines and Chinese Communist Party discipline and Punishment Regulations column 1 by 2020 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation。 結(jié) 束 語 多媒體教學(xué)已被實(shí)踐證明是一種行之有效的 輔助 教學(xué)手段。 “協(xié)商”與“會(huì)話”──協(xié)商與會(huì)話過程主要通過語言作媒介,這就要求計(jì)算機(jī)輔助教學(xué)系統(tǒng)必須要有語音功能,即要用多媒體計(jì)算機(jī)才能支持。 智能輔助教學(xué)系統(tǒng)具有能與人類優(yōu)秀教師相媲美的下述功能: 13 / 60 ( 1) 了解每個(gè)學(xué)生的學(xué)習(xí)能力、認(rèn)知特點(diǎn)和當(dāng)前知識(shí)水平; ( 2) 能根據(jù)學(xué)生的不同特點(diǎn)選擇最適當(dāng)?shù)慕虒W(xué)內(nèi)容和教學(xué)方法,并可對(duì)學(xué)生進(jìn)行有針對(duì)性的個(gè)別指導(dǎo); ( 3) 允許學(xué)生用自然語言與“計(jì)算機(jī)導(dǎo)師”進(jìn)行人機(jī)對(duì)話。休斯頓大學(xué)和 NASA(美國國家航空和宇航局 )約翰遜空間中心的研究人員建造了一種稱之為“虛擬物理實(shí)驗(yàn)室”的系統(tǒng),利用該系統(tǒng)可以直觀地研究重力、慣性這類物理現(xiàn)象。這是多媒體教育應(yīng)用中十分值得引起我們重視的一個(gè)新趨勢(shì),也是當(dāng)前發(fā)展最快的一個(gè)趨勢(shì),我們必須迎
