牛頓單位 的英文怎麼說
中文拼音 [niúdùndānwèi]
牛頓單位
英文
newton unit-
The " minimum friction level " of 25 micro newton established by ittf is so high that only pimpled - out rubbers with total friction will be homologated after 01 july 2008 ( the friction level concerns both the surface and the side of the pimples )
2008年7月1日起，國際乒聯訂立相當高的25微牛頓單位「最低摩擦度」只有符合這個摩擦度的正貼膠皮才認可使用（所指的摩擦度包含膠粒的表面和邊緣位置） 。In this section we depart briefly from the subject of newton's laws to discuss the question of units.
在這一節中，我們暫時離開牛頓定律來討論一下單位問題。The si unit of force is the newton, n, which is derived from the si base units of mass ( kilogram ), length ( metre ) and time ( second )
力的米制單位是牛頓（ n ） 。牛頓是引伸自質量（千克） ，長度（米）及時間（秒）的三個si基本單位。牛頓是使一千克質量的物體產生1ms2加速度的力。Based on interval the computation cost of interval newton algorithm is larger than the general newton iteration method. the computation time of interval newton algorithm tends to grow exponentially with the dimension. even for small problems, interval newton algorithm often requires enormous computation time if the nonlinearity of the problem is very large or the problem is ill - conditioned
但是由於區間牛頓法是以區間為迭代單位，其計算量遠大於一般的牛頓類迭代法，其計算時間隨著方程組維數n的增加而呈指數增長；而且即使在維數n很小時，若方程組的非線性程度很強或方程組為病態，所需的計算時間也很大。分享友人
