Well, if I have a gradient field, then if I try to compute this line integral, I know it will be the value of the function at the end point minus the value at the starting point.
如果有一个梯度场,然后想计算线积分,我知道积分值是,起点的函数值减去终点的函数值。
At the end of each month, the amount of money deposited by the user is divided by the number of clicks (minus a 10% fee for Flattr) and distributed among the site owners.
在每个月的月底,用户金所有额是以点击数(减去10%的Flattr费)加上网站所有者之间的分配。
That was 137 days ago and the end is nowhere near: The fries look as fresh as the day they came out of the fryer, and the burger — minus a little patty shrinkage — is virtually unchanged.
但是终点却遥遥无期:炸薯条至今看上去和它刚出锅时一样新鲜,而汉堡只有肉饼有微微的缩小——看上去一点没变。戴维斯计划直到它们有变化再停止。但是她最好做好长期准备。
475 Multiply by 1.7475 787kJ/mol and you end up with minus 787 kilojoules per mole.
乘以1。,最终得到。
For the carbon, we start with 4 valence electrons, we have 0 lone pair electrons minus 4, and we end up with a formal charge of 0.
对于碳,我们从四个价电子开始,我们有零个孤对电子,再减去四,最终我们有零个形式电荷。
So I'm first going to look for something that's not in the list, I'm going to see, is minus 1 in this list, so it's going to be at the far end, and if I do that in the basic case, bam.
如果我试试第一种最基本的方法,噢,一下就完成了对不对?,因为这种方法查了下第一个元素,然后发现目标数比较下,因为目标数小于第一个元素。
