This is my nephew, first baby of my elder sister, he's looked so cute. This taken during CNY 06 at my hometown....
However he is going back to KL soon loh..Anyways, wish he "fast tall grow big"...Gong Xi Fatt Chai

首先,从花纹样式来看。外表带有颗粒或螺纹凸起的安全套,可以增加对阴道壁的摩擦刺激,能更好地取悦女方。相比较而言,因为太粗的乳胶颗粒容易导致安全套出现裂缝,所以在合格的产品中,颗粒大小会受到限制,这就使螺纹安全套的快感比颗粒安全套更强烈一些。
其次,从色彩和香型来看。市场上的避孕套色彩纷呈,有红、白、粉、紫、蓝等20多种。自上世纪90年代初起,厂家还推出了添加各种香料的安全套,常见的 有玫瑰香型、桂花香型等几种。应该说,彩色和香型主要是为了改善一些人对安全套的反感心理,同时也是为了增加吸引力。因为人们可根据对颜色的偏爱或当时的 心境,选择使用不同的安全套。
需要提醒大家的是,时下流行的草莓、巧克力等香料型安全套,容易导致妇女阴道发炎。如果要选这类产品,一定要密切关注女性是否有阴道分泌物异常问题,并且尽量少用。
The Laplace transform of a function f(t), defined for all real numbers t ≥ 0, is the function F(s), defined by:
The lower limit of 0 − is short notation to mean and assures the inclusion of the entire Dirac delta function
at 0 if there is such an impulse in f(t) at 0.
The parameter s is in general complex:
This integral transform has a number of properties that make it useful for analysing linear dynamical systems. The most significant advantage is that differentiation and integration become multiplication and division, respectively, with s. (This is similar to the way that logarithms change an operation of multiplication of numbers to addition of their logarithms.) This changes integral equations and differential equations to polynomial equations, which are much easier to solve.
The Laplace transform is named in honor of Pierre-Simon Laplace, who used the transform in his work on probability theory. The Laplace transform was discovered originally by Leonhard Euler.
And some more this only the introduction.....bbbbbaaaaaadddddd...
So, if you are interesting or going for engineering course, better consider it carefully, else you will feel like me one day... Good day!!!
