implicit 和explicit 代表什么含义

at least implicitly 什么意思?
当作为单独的插入语,这个固定词汇是什么意思啊?例如：culture and some other attribute is presented, at least implicitly, as if one causes the other, 其中那个at least implicitly 如何翻译?
多谢~~~

Implicit super constructor People() is undefined.Must explicitly invoke another constructor

xIny+2y=2x^3 use implicit differentiation to find y'
我算到是y'=6x^2*y-yIny-x/2y
但书上答案是y'=6x^2*y-yIny/x+2y
我怎麼算也算不到x在分母呢,是书错还是我错...

The Unusual Stone Which Expressing the Ideas Implicitly - On Chinese Stone Culture
为什么which直接用expressing?

英语翻译
例句如下
Implicit in the topic is the expectation that you will analyze the reading and arrive at some insights into patterns and relationships about the subject.
自己试着翻译一下 前面会
主题中隐含的是一种期望 什么样的期望呢?你能分析阅读材料 能 arrive at A into B and C about D.
请问ABCD 是怎么个关系 是arrive at A into{ (B and C) about D}.
还是 arrive at A into B and {C about D.}
希望英语牛人能看懂我的提问
对不起
请问ABCD 是怎么个关系 是arrive at A into{ (B and C) about D}.
还是 arrive at A into {B and （C about D）}.

very 在这句话里的用法
The faculty,by its very existence,says implicitly:"We have been aided by many people,and by many books,in our attempt to make ourselves some sort of storehouse of human experience."
如题,请问这句话里 very 类似的用法还能给点例子吗?

谁能告诉我explicit theme 和 implicit theme的中文意思?我大致理解了,还是不太清楚.在帮忙给explicit theme 和 implicit theme举几个例子.比如说XXX书里面的explicit theme是（）（）（）?Implicit theme是（）（）（）?
举几个例子吧！我把分提高到15了。

求解一道用隐函数求偏微分的问题
use implicit differentiation to find (partial Z/ partial X) and (partial Z / partial Y)
公式是：e^z=xyz

Find the implicit differentiation of the function shown below x^3y^2+6xy+5y^3x^2=5
x^3y^2 + 6xy + 5y^3x^2 =5
