查询词典 unknown

"Hazy" Good ambiguous name, yesterday in a rare fog enveloped the entire City, a very silly sense of visibility below 10 meters, just go out would be a kind of very exciting feeling, in that space of the Mist stay for a long time, feeling a boring person can not see anything, can only be seen a few zero-Mist dilute the flashing lights of the cars, you do not know what the status outside the 10 meters, or even the traffic lights, you do not know what you will face is how the situation, everything is unknown, that Mende feeling may just be time for everyone to face the unknown of a mind's instinctive reaction to fear.

"雾蒙蒙"好暧昧的一个名字，昨天一场罕见的大雾笼罩整个岛城，很懵懂的感觉，能见度低于十米，刚刚外出会有种很兴奋的感觉，在那种蒙蒙的空间里呆久了，感觉很闷，看不见任何东西，只能蒙蒙中见到几个零稀的车灯在闪烁，你可以不知道十米以外是怎样的状况，甚至是红绿灯，你也不知道你将面临的是怎样的状况，一切都是未知，那种闷得感觉，可能只是每个人面临未知时的一种内心恐惧的本能反应。

Secondly, based on the different structure characteristics and additional conditions, we study several kinds of inverse problems of pseudoparabolic equations. One is a kind of pseudoparabolic inverse problem of identifying a constant coefficient solved by combining the formal solution of the problem and the additional condition properly. The second is the pseudoparabolic inverse problems of identifying an unknown boundary function and an unknown source term solved by using the Riemann function method to get the formal solution of the problem and then using the additional condition to transform the problem into a Volterra integral equation of the second kind. The third is a kind of backward heat flow problem of nonlinear pseudoparabolic equation solved by combining the Riemann function method and the fixed point theory properly.
