In the past hundred years,humans have begun destroying rainforests in search of three major resources (资源):land for crops,wood for paper and other products, land for raising farm animals.This action affects the environment as a whole.For example,a lot of carbon dioxide (...
time inverse problems, taking the Bayesian approach for estimating carbon dioxide (CO2) emissions and uptake (a.k.a. fluxes) as a prototypical example. The first algorithm can be used to efficiently multiply two matrices, as long as one can be expressed as a Kronecker product of two smaller...
For example,a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit(受益). There are two main reasons for this . Firstly when people cut ...

for instance, those with prosopagnosia or "face blindness". （有些人很难辨认面孔，例如患有失面（面部失认症）的人。）The Earth's atmosphere is composed of several gases, for instance, nitrogen, oxygen and carbon dioxide. （地球的大气层由几种气体组成，例如氮气、氧气和二氧化碳。）
