关于安全的英语文章 关于友谊的英语文章安全这个平凡的字眼，可它却又是千万生命的起，安全乃是重中之重的事物，没有安全，就算你将来是万亿富翁，也是幻想。安全不能指望事后诸葛，为了安全须三思而后行。下面是WTT精心整理的关于安全的英语精选的文章，希望能够帮到大家!关于安全的英语文章篇【1】Over the past couple of years, several cases of the food scandal have been disclosed on various media.The problem of food security has bee a hot button across society.The prevalence of food insecurity has greatly impacted public health, which the government could not afford to ignore, according to the online edition of the People Daily。There are a couple of driving forces, I would argue, behind this undesirable tide.First, in the course of the rapid economic evolution, we ignore moral education, giving rise to the rising rate of the problem.More importantly, the lack of adequate regulation and punishment on those illegal producers enforces the trend。As Confucius instructed, it is better late than never.Prompt and strict measures should be taken to turn back this evil trend.The government should launch a massive moral caign to educate all citizens and draw up tougher laws to crack down on those irresponsible corporations and prohibit them from entering the food industry again.I am firmly convinced that through our bined efforts we are bound to enjoy more risk-free foods in the days ahead。关于安全的英语文章篇【2】Earlier this week, as I fondled my Windows 8 Samsung tablet and tried to make a hands-on video, I cursed often and loudly at the smudged and greasy screen.Underneath those gray smears a beautiful super AMOLED screen was simply gagging to be seen.Then, this morning, I was reading some about a pany called Visual Pla that can turn any surface into a touchscreen using a transparent, few-millimeter-thick nanowire film.These “touch foils,” as Visual Pla calls them, can be up to 167 inches wide (4.2 meters) and are perfect for turning large TVs or projected images into a touch interface.Theres no doubt that touchscreens make interaction easier - anyone, including two-year-olds, can manipulate a touch interface - and the concept of touch-interactive walls and shop windows and tables and mirrors is enough to make me dribble with futuristic anticipation.But just for a moment.just imagine living in a world where almost every surface has been smudged by dirty, chubby, probing fingertips.I go nuts if someone even threatens to touch my LCD screen.and yet Microsoft and Visual Pla assure us that were moving towards a world where every display should be touched?We already live in a society where people avoid touching handles and rails and carry around hand sanitizer.and yet were meant to happily share an interactive shop window or bathroom mirror with 5,000 other shoppers? Im not a germaphobe, but I would certainly recoil from a touchscreen thats covered in e_creta or the remnants of a McDonalds meal.Perhaps youll get a free tube of sanitizer with every purchase.Then theres actual puter usage.Theres no denying that Windows 8′s Metro-style Start screen is a touch- and gesture-oriented interface, and Apples OS _ is almost certainly moving in a similar direction - but where does that leave graphic designers? Am I meant to poke and slide around the Metro interface.and then edit photos with a greasy screen? Ive already had an e_perience where I thought a flyspeck of crap on the screen was part of a photo, and thats only going to get 100 times worse with touchscreen desktops and laptops.There is no denying that touchscreen interfaces enable new swaths of society to use puters - and like the moditization of fresh water, electricity, and the inter, that is undoubtedly a good thing.Theres simply no way that touchscreens, in their current, easily-smeared form can work, though.Are we all meant to carry a microfiber cloth and some non-alcoholic cleaner in our pocket? Should shops and offices retain the services of an official Screen Cleaner who toddles around with a bucket and squeegee? Maybe youll even be able to get your tablet de-smudged for a couple of dollars at some red traffic lights or in a parking lot.No, realistically we need a new touchscreen technology that can clean itself - or rather, a new kind of glass that is smear-resistant, or capable of shaking dirt and grime off, in the same way that camera sensors can clean themselves using ultrasonic motors.Or, perhaps by government mandate, we could all wear a “touch glove.” There would be fines for poking with an unprotected finger, of course - but on the flip side, I would jump at any chance to walk around looking like Michael Jackson.关于安全的英语文章篇【3】In the future, you could use your heartbeat for a passwordHAVING trouble remembering your password? Perhaps you need to use your heart instead of your head.An encryption system that uses the unique pattern of your heartbeat as a secret key could potentially be used to make a hard drive that will only decrypt in response to your touch.Our heartbeats follow an irregular pattern that never quite repeats and that is unique to everyone.Chun-Liang Lin at the National Chung Hsing University in Taichung, Taiwan, and colleagues used an electrocardiograph (ECG) to e_tract the unique mathematical features underlying this pattern.They then used the information to generate a secret key that forms part of an encryption scheme based on the mathematics of chaos theory, by which small changes in initial conditions lead to very different outes.As a proof of concept, Lin's system currently takes the user's ECG reading from each palm once, and a key based on that reading is stored and used for all later decryptions.He says the goal is to build the system into e_ternal hard drives and other devices that can be decrypted and encrypted simply by touching them.“关于安全的英语文章”的人【end】第 8 页 共 8 页
