Leaked by the Pentagon's news service, Military Affairs to quell scuttlebutt racing through the ranks-and perhaps warn the world-a US Air Force B-52 strategic bomber "mistakenly" loaded with six nuclear cruise missiles took off from Minot Air Force Base in North Dakota on August 30, 2007 and flew for more than three ...

泄露五角大楼的新闻服务，军事事务，以平息scuttlebutt赛车通过的行列，和可能发出警告，世界-美国空军的B - 52战略轰炸机"误"上有六核巡航导弹起飞迈诺特空军基地，在北达科他州对2007年8月30日飞到了三个多。。。

If we allow these 10105 molecules to randomly permutate, the rate of permutation is ten thousand (104) times per second. If the age of the universe was thirty billion years (1018 seconds), then from the beginning of the universe until now, the total permutations were 10127 times (10105x1018x104), which is not even enough time to develop one correct nucleotide sequence for one molecule of DNA.

如果让这10105个分子随机组合，令组合的速率为每秒一万次（104），假设宇宙的年龄为三百亿年（1018秒），那么，从宇宙形成到现在，一共可以产生的组合方式是10127次（10105x1018x104），还不足以产生一个有正确核亘酸排列组合序列的DNA分子2！

They have distinctive compositions, and display the compositional trends: from Mg and Ca-enrichment towards Fe-enrichment from big phenocryst—the core of small phenocryst—the rim of small phenocryst and microcrystals, typical characterisitc of tholeiite series.

这三种类型的辉石在成分上有明显的差异，从大斑晶辉石—小斑晶辉石核部—小斑晶辉石边部和基质辉石，成分由富镁、钙向富铁方向演化，显示出拉斑玄武系列的特点。

A successful strategy leading to one-, two-, and three-dimensional (1D, 2D, 3D) systems is the using of metal cations of link reactively stable coordination compounds containing potential bridging blocks, i.e.
