用劲度系数k=500N/m的轻弹簧，水平拉一木板使它沿水平桌面做匀速直线运动，弹簧长度L1=12cm.若在木板上加一个质量m=5kg的铁块，仍用原弹簧拉住它沿水平桌面做匀速直线运动，弹簧的长度L2=14cm，则木板与水平桌面间的动摩擦因数为多少？（g取10m/s2）
如图所示，光滑水平面上，一细线的一端固定于倾角为45°质量为M的光滑楔形滑块A的顶端P处，细线另一端拴一质量为m的小球。
（1）当力F向左拉A，为使小球不离开滑块，求力F的取值范围。
（2）当力F向左拉A，A和球以2g加速度共同向左运动时，线中拉力T多大？
（3）若力F改为向右，为使小球相对A发生相对运动，求F的取值范围。

Jeffery Deaver looks more like a brainy villain (反派人物) in a James Bond movie than a "00" agent
in Her Majesty's secret service.Best known for his thrillers starring criminalist (刑事专家) Lincoln Rhyme, Jeffery Deaver has a new mission: Bring Bond into the 21st century in a new 007 novel.
The yet-to-be-named book is cryptically (隐秘地) referred to as "Project X" by Ian Fleming
Publications Ltd., which owns the rights to Fleming's work.Most of the details surrounding Project X, to
be published in May, are being kept under wraps, but under gentle coaxing (用好话劝诱) Deaver begins
to spill his guts."The novel," he says, "is set in the present day, in 2011.Bond is a young agent for the
British secret service.He's 29 or 30 years old, and he's an Afghan war vet." That in itself is big news.
After all, if Bond were aging in real time - he first appeared on the screen in 1953 - the now doddering
(老态龙钟的) 007 would be nearly 90.
But first up: a new stand-alone Deaver novel, Edge (Simon & Schuster, $26.99), to be published
Tuesday.It's about a federal agent who risks his life to protect a Washington police detective from a man
hired to extract information from him using any means at his disposal (任由个人支配的).
Sipping coffee while seated on a leather chair in a sitting room decorated with portraits of his dogs
and show ribbons, the mild-mannered author who writes about murderers and serial killers talks about
his career and the solid fan base that has allowed him to pursue writing full time since 1990."I may not
sell as many books as John Grisham (although he has sold a cool 20 million), but I have a very loyal fan
base," says Deaver, 60, who wrote some of his novels while working as a Wall Street lawyer.Deaver's
initiation into the Bond family - more than 100 million 007 novels have sold worldwide - could
significantly raise his profile (知名度).
Other novelists have written Bond novels since Ian Fleming's death in 1964 - including Kingsley Amis,
John Gardner and, most recently, Sebastian Faulks - but they all took place in the original era.Deaver is
taking a new approach."There's no more Cold War to fight," says Deaver, so his new Bond, of the
Fleming estate, will fight "post-9/11 evil." "I want to stay true to the original James Bond, who many
people don't know much about," he says, referring to the secret agent Fleming portrayed in 14 novels,
and not the movie Bond."People know Daniel Craig, they know Pierce Brosnan , they know Roger
Moore and Sean Connery , all of whom brought a great deal to the stories of 007.But the original Bond
was a very dark, edgy (另类的) character."
