-“This road used to be much narrower,” one of the tourists _

For many of us,the idea of a family is a lot narrower than it used to be.Today children go away to college,and take up jobs wherever chances seem greatest.So instead of growing up in a family with grandparents,aunts,uncles and cousins,many of us are truly connected only to our parents and brothers.Many kids today know little of the lives of their relatives and don't care deeply about them.Whether we realize it or not,this feeling of being disconnected makes people feel a kind of lonely.“People need to feel connected,”says Joy Browne,a doctor in the U.S.“And they will do it in the easiest ways.”When family members aren't connected,what could be easier than forming(形成) a connection to famous people?This isn't something unusual,of course.People cried when Mei Yanfang died in 2003.It's natural and in most ways harmless to feel that way.But that's unhealthy,because these relationships(关系) aren't two-way.For that,we need to stay connected to our own families.We'll never turn back the clock to keep families from breaking.But parents can help by telling their children stories about their grandparents,aunts and cousins,and by telling them the children's latest activities and interests.We can use technology to keep connected with each other.It's easy to send e-mails to granddad Better yet,take a vacation with members o

The narrower the input beam,the higher the critical angle and the smaller the deviation of q0 from .The guided-wave amplitude is always smaller than that for the soliton beam in a uniform medium and approaches as guiding parameter p ->!0.
Numerical simulations indicate that beams moving along the grating slowly radiate—an effect not captured by the effective-particle approach.When solitons cross the waveguide,they lose a fraction of their energy because the wing of the soliton spatial spectrum overlaps the spatial spectrum of the guided mode.The radiation rate increases as the incident angle approaches angleαb corresponding to the edge of the first Brillouin zone.12,13 The energy losses caused by the excitation of consecutive waveguides result in the slant soliton beam being trapped in one of the grating channels.This situation is shown in Fig.1(c).Note that the propagation distance at which trapping occurs is relatively small.Intuitively,it is clear that the larger the incident angle,the higher the channel number at which trapping occurs.Such radiative trapping has much in common with the properties of discrete solitons in waveguide arrays;
