四倍的

As Princeton bioethicist Peter Singer notes in his new book, if we fed that grain to the 1.4 billion people who are living in abject poverty, each of them would be provided more than half a ton of grain, or about 3 pounds of grain/day － that's twice the grain they would need to survive.

正如普林斯顿大学生物伦理学家彼得辛格在其新书指出，如果我们将此谷物粮食餵养活在赤贫中的十四亿人，将可供给每人超过半吨的谷物，或约一天三磅的谷物那是两倍於其维生所需。

This topic mainly adopts monolithic integrated circuit AT89C2051 to design a practical digital inductance reflectoscope reflector, the scope of inductance quantity survey is 0.1mH ~ 20H, uses two half digital demonstration, the biggest demonstration number is 199, the Reading unit unifies with mH, the measuring range divides four keep bracket, the reading respectively rides by the corresponding percentage.

本课题主要采用单片机AT89C2051设计一个实用的数字电感测试仪，电感量的测量范围为0.1mH～20H，采用两位半数字显示，最大显示值为199，读数单位统一用毫亨，量程分四挡，读数分别乘以相应的倍率。

Orthogonality L9(34) methods on the basis of the concentrations of caladium alkali was used to optimize the preparation technology. The final technology was determined as follow:12 times water soaking herbs, volatility oil distilled by vapor 2h, decoction 2 times every 1.5h and 85% alcohol forming granules.

经正交实验四因素三水平L9(34)方法，以西贝碱的含量为检测结果，优选了最佳的提取工艺，确定了用12倍量水浸泡4h，以水蒸汽蒸馏法收集挥发油2h，煎煮1.5h，干膏用85%乙醇制粒的科学工艺。
