When we think about the future of the universe, we can see our "track" many billions of years into the future, but after that there are decision points to be dealt with and possible fates to consider. The goal of science is to reduce the ambiguity at the decision points and find the true road that will be followed.
According to the passage, it is difficult to be certain about the distant future of the universe because we______.
A.have too many conflicting theories
B.do not have enough funding to continue our research
C.are not sure how the universe is put together
D.have focused our investigations on the moon and planets
A.二进制数只由两位数组成
B.二进制转化为八进制时,当分组不足3位,分别向高位或低位补0凑成3位
C.十进制转化为其它进制时,其整数部分和小数部分在转换时需作不同的计算
D.八进制转化为十六进制时,可以通过二进制数作为中间桥梁,先转化为二进制数,再转化为十六进制
E.二进制转化为十六进制时,当分组不足4位,分别向高位或低位补0凑成4位
773.15K时,的平衡常数为8.39×10-4Pa-1。当SO2=7.8%,O2=10.8%,N2=81.4%(体积分数)的气体由硫铁烧炉进入转化器时,一部分SO2变为SO3达到平衡而导出。若此时转化器内保持101.325kPa、773.15K,试求导出的气体组成。
