    Abstract: 首先第一章,先介紹Ostrowski不等式令 f: [a,b] → R 在 [a,b] 上是一個有界變分的函數。則下列不等式

    |∫_a^b▒〖f(x) dx-(b-a)f(x)〗|≤[1/2 (b-a)+|x-(a+b)/2|] V_a^b (f)

    對於每一個 x 在 (a,b)上都成立,這裡的 V_a^b (f) 是 f 在 [a,b] 上的全變分。
    第四章,我們要介紹一些特殊的加權的 Ostrowski不等式和一些特殊的改良的 Ostrowski 不等式。我們得到了幾個重要的不等式。像是不等式在有界變分函數之下加權的梯形積分及在有界變分函數之下 ‘‘加權的 Ostrowski’’ 不等式。
    In this dissertation, it consists of five chapters.
    In the first chapter, we introduce Ostrowski inequality for function of bounded variation. The inequality
    |∫_a^b▒〖f(x) dx-(b-a)f(x)〗|≤[1/2 (b-a)+|x-(a+b)/2|] V_a^b (f)
    holds for all x∈(a,b) where f: [a,b] → R is a mapping of bounded variation on [a,b] and V_a^b (f) is the total variation of f on the interval [a,b].
    In the second chapter, we introduce Some established Ostrowski''s type inequalities.
    In the third chapter, we present some refinements of Ostrowski inequalities.
    In the forth chapter, we present some particular weighted ostrowski inequality and some particular integral of improved ostrowski Inequality. We get some important results. Some inequalities like the weighted trapezoid inequality for mappings of bounded variation and the ‘weighted Ostrowski inequality for mappings of bounded variation.
    Finally, we discuss Some Particular integral inequality about my main results.
