The story is told about the sergeant who stopped at the jewelry store every morning at nine o’clock and compared and reset his watch with the chronometer in the window. Finally, one day the sergeant went into the store and complimented the owner on the accuracy of the chronometer. “Is it according to time signals from Arlington？” Asked the sergeant. “No,” said the owner, “I set it by the five o’clock cannon fired from the fort each afternoon. Tell me, Sergeant, why do you stop every day and check your watch？” The sergeant replied, “I’m the gunner at the fort!” Is the feedback prevalent in this case positive or negative？ The jeweler’s chronometer loses 3 minutes each 24-hor period and the sergeant’s watch loses 2 minutes during each eight hours. If the time of the chronometer is correct at 9 o’clock this Monday morning, what is the net time error when the cannon is firing at the fort of the next Monday？

这是一篇有关应变传感器的新闻报道，请将划线部分的单词或结构翻译为汉语： Physicists Have Created the Most Sensitive Strain Sensor Ever Made TOPICS: Biotechnology，Materials Science，University Of Sussex By UNIVERSITY OF SUSSEX JUNE 4, 2020 The sensor, developed by the Materials Physics Group at the University of Sussex, can stretch up to 80 times higher strain than ❶strain gauges currently on the market and show resistance changes 100 times higher than the most sensitive materials in research development. The research team believes the sensors could bring new levels of sensitivity to ❷wearable tech measuring patients’ vital signs and to systems monitoring buildings and bridges’ structural integrity. Marcus O’Mara, from the School of Mathematical and Physical Sciences at the University of Sussex, said: “The next wave of ❸strain sensing technology uses elastic materials like rubber imbued with conductive materials such as ❹graphene or silver nanoparticles, and has been in development for over a decade now. “We believe these sensors are a big step forward. When compared to both linear and non-linear strain sensors referenced in the scientific literature, our sensors exhibit ❺the largest absolute change in resistance ever reported.”

HERE WE GOOGLE AGAIN

Google dominates the Internet-search business, such as Netscape once ruled in Web browsers and Real Networks did in media players. Begun as a research project by two graduate students in 1998, Google today carries out more than 200 million searches a day and is estimated to have had $1 billion income last year, mainly from advertising sector.

It is the most visited search site, accounting for 35% of search-engine visits — compared with 28% for Yahoo, 16% for AOL and 15% for Microsoft's MSN, according to comScore Networks, a market-research company. But that masks its tree influence. Google's technology is used to power searches on other sites, such as Yahoo and AOL (though Yahoo plans to use its own technology soon). Taking this into account makes Google responsible for around 80% of all Internet searches. The company is now preparing for a stock market flotation in the next few months.

Google's power makes it just the sort of company that Microsoft typically tries to squash. At the World Economic Forum in Davos last week, Mr. Gates admitted that Google's search technology was "way better" than Microsoft's, and identified Internet search as a key focus for his company.

Google, Netscape amt Real Networks all play a very important role in their own field.
