However, its rapid development has greatly changed understanding, the way of people’s exchanges and emotion, which lets some relationships in real time bee virtual and indirect, enables the practical skills of people to drop in, and also makes people’s mental problems emerge, such as loneliness and indifference, trust crisis and so on. All of this makes the relationships that seem to get closer and closer under the influence of the Inter bee more distant, lack of mutual understanding, and be on the alert between people. So the study for the Instant messaging to the impact of interpersonal relationships has important practical significance, and attracts increasing attention. As a kind of convenient socket munication technique, instant messaging software has deep into people’s heart, application range from single work chat tool to information munication platform. Due to importance, finding out exiting problems and localization seems especially imperious. According to a mount of literature summary and survey to practical situation, two facets are set forth as follows:First: at present, IM software centralizes under the MS Window platform on the whole, not taking int account the need of users who apply intelligence support facility。是一種終端連網(wǎng)即時(shí)通訊網(wǎng)絡(luò)的服務(wù)。它的產(chǎn)生有著深刻的社會(huì)和技術(shù)的原因。從這點(diǎn)上講，即時(shí)通訊的出現(xiàn)改變了人們的溝通方式和交友文化，大大拓展了個(gè)人生活交流的空間。可以說，即時(shí)通訊 6 的發(fā)展把后 PC時(shí)代的特征體現(xiàn)的淋漓盡致，人們從來沒有像今天這樣感受到天涯咫尺。截止到目前，全球約有近 3 億多人使用即時(shí)通訊軟件進(jìn)行交流，正因?yàn)榧磿r(shí)通訊軟件擁有數(shù)以億計(jì)的用戶和迅速增長(zhǎng)的市場(chǎng)，所以各個(gè)公司都盯上了中國這個(gè)潛在的最大市場(chǎng)，一時(shí)間，即時(shí)通訊市場(chǎng)硝煙四起。這天標(biāo)志著In
