Analysis of security incidents and frequent cause of the blast cells
In recent years, as people's living standards improve, battery life of the ever-increasing frequency, people familiar with digital cameras, notebook, MP3, mobile phones Inspiron 5160 battery, Inspiron 6000 battery and other electronic products often can not do without the battery. However, the frequency of accidents caused by the battery is also rising, from the iPhone, Nokia's mobile phone to the cottage, the battery explosion not uncommon, even in our lives will be commonly used in cell No. 5 explosion.
Recently, the network appears Nanfu, Ba Jin and other well-known brand battery to explode phenomena reported, Xiaobian briefly summarize the family in this common cause battery explosion.
The battery cause of the explosion that there are two, one is a "non-normal use," such as the battery is shorted, the battery used by the current is too large, non-rechargeable batteries Inspiron 630m battery, Inspiron 6400 battery Naqu charge, the use of high temperature, or use the battery when it is negative anti-loaded.
Another reason is that "there is no reason blew." Mainly occurred in fake brand-name batteries. Such an explosion is not because the battery, there are inflammable and explosive substances, but because of inferior material and impurities within the battery, but also lacking substance, leading to the production of gas inside the battery, the internal pressure, so easy, "blew."
In addition, rechargeable batteries, the charger can easily result in improper use of the battery explosion.
Recently, consumer reaction, put the batteries in quartz also led to an explosion, we will do follow-up reports on this incident Inspiron 640m battery, Inspiron 700m battery, Inspiron 8500 battery.

(0)Silicon Valley technology companies pay 14% decline compared to 2000
The U.S. Bureau of Labor Statistics (Bureau of Labor Statistics) report released yesterday shows that since 2000, Silicon Valley technology Inspiron 1150 battery, Inspiron 1420 battery sector earnings are down about 14%, indicating that this region from the Internet bubble burst have not yet completely recovered.
Pay status
The U.S. Bureau of Labor Statistics data show that Silicon Valley technology industry employees in 2008, the average salary of 10.3850 million U.S. dollars, far below the 2000 12.0064 million U.S. dollars. The reason why this situation occurs because the value of equity-based compensation has shrunk dramatically. First half of 2009, Silicon Valley technology sector salaries have increased over 2008, reaching 10.5500 U.S. dollars.
Century and the beginning of the Internet bubble burst led to massive layoffs in Silicon Valley technology companies, semiconductor, Internet and telecommunications companies have emerged the biggest loss of history. The U.S. Bureau of Labor Statistics economist llama Sur Marne (Amar Mann), said Silicon Valley from the recent economic crisis in the speed of recovery may be very slow Inspiron 1521 battery Inspiron 1721 battery, Inspiron 2600 battery.
Isle of Man said: "The trend is even more like a U-shaped, is gradually picked up." He also said that in previous economic cycles, venture capital technology industry downturn led to slower employment growth, this recovery may be will follow the same pattern.
Since 2000, Silicon Valley technology jobs has been reduced by 13.4 million. Ended in June last year, 9 months, the decrease of 3 million. Isle of Man that the whole Silicon Valley, currently has 410,000 IT jobs. From 2000 to 2004, the region's jobs has been declining, and then began to increase, until the recent economic crisis. He said that science and technology positions in the region accounted for about one seventh of all jobs.
Unemployment
According to the U.S. Bureau of Labor Statistics data from 2000 to 2004, Silicon Valley technology staff salaries fell by 16%, then in mid-2009, an increase of 4.4%. Taking into account inflation, the region tech workers in the current pay levels in 1998 rather Inspiron 2650 battery, Inspiron 5150 battery, Inspiron 5160 battery, Inspiron 6000 battery.
According to California Labor Market Information Division (Labor Market Information Division) of data, including Mountain View, Palo Alto and San Jose and other cities in Santa Clara County in December last year, the unemployment rate is 11.2%; with Menlo Park and Redwood City and other cities in San Mateo County last year, the unemployment rate was 8.6%. Throughout the California unemployment rate of 12.1% over the same period.
National Venture Capital Association (National Venture Capital Association) data show that in 2009 the total U.S. venture investment fell 37%, only 17.7 billion.
The U.S. Bureau of Labor Statistics report shows, despite the sharp drop, but the Silicon Valley's tech workers in the average salary is still higher than 61% higher than other parts of the United States Inspiron 630m battery, Inspiron 6400 battery.
