即使有美味的食物,不去品尝,就不知道它的甘美。即使有最好的道理,不学习,就不知道它的好处。所以学习之后才会知道自己的不足,教过别人之后才会知道自己也有理解不透彻的地方。知道了自己的不足,这样才能知道如何反省自己;知道了自己不懂的地方,这样才能自我勉励。所以说:“教和学是互相促进的。教别人也能增长自己的学问。”《兑命》中说道:“教人是学习的一半。"大概说的就是这个道理吧。

又是一年的九月十日教师节到来了,在这个特殊的日子里,我想用自己最真诚的语言对我的老师说一声,老师您好!老师您辛苦了!从我上小一年级到现在小学四级,教过我的老师有好几位,其中给我最多关心和帮助的是我的班主任老师—严老师。记得一次语文课上,我没认真听讲,您用那双锐利的眼睛望着我,让我突然认识到了错误连忙认真听讲。当我获奖时,您用赞许的眼神看着我,同时好像在提醒我:“不要骄傲,继续努力!”就是您这双眼神,让我的学习成绩一天比一天好。严老师您不仅是一位严厉的老师,更像一位慈母。有一次,我在上课时,突然感觉全身无力,强打着精神听老师讲课。严老师发现了我一副无精打采的样子,就快步走到了我的书桌旁,说:“你生病了吗?”我有气无力地说:“我好像生病了。”严老师摸了摸我的额头,说:“好烫!我带你去医院!”说完,就背着我跑到了医院,这时,我已经睡着了。当我醒来时,我发现我正躺在病床上,正在打点滴。严老师坐在我的身旁,用关切地眼神望着我,说:“蓉蓉,好些了吗?”我感动得流着眼泪说:“好些了,谢谢老师。”严老师,感谢您四年以来以我学习上的帮助,生活上的关心,您是我生命中的指路明灯。我永远感激您!径口小学四年级:zizzz123

英文翻译 大家帮忙看看 谢谢
Stephen Few describes the search and definition of content-related parameters and their reference as
a core task in visualization:
“Most data analysis involves searching
for and making sense of relationships among values and making
comparisons that involve more than just two values at a time.”

史蒂芬很少描述搜索和内容相关的参数的定义和参考.
在可视化的一个核心任务中他说:
“大多数时候数据分析涉及到搜索,为了得到意义和值之间的关系,比较两个值,要很多次.”

小小翻译 谢谢帮忙The finite difference approximation of the Jacobian
小小翻译 谢谢帮忙
The finite difference approximation of the Jacobian matrix is required at every iteration.
The method also uses the Jacobian to minimize the sum of squares in a local region of the parameter space.
Basically,this is a optimal compromise between steepest descent,efficient far from the minimum,and the Gauss-Newton method,only efficient when close to the minimum.

雅可比矩阵的有限差分法在每一次迭代中都是必须的.
此方法也应用雅可比行列式来最小化参数空间局部区域的平方和.
基本上,这是最陡下降法(远离最小值有效)和高斯-牛顿法(接近最小值有效)最理想的折中办法.
