PAT has two parameteres τ 2 and I2, 2 is annihilation life, I2 is annihilation intensity.

Typical examples demonstrate that the difference between I1 and I2 could be significant for certain parameters.

典型例子表明，对某些卫星参数，I2及I1的差别是显著的。

It is concluded that the flexibility of i2 technology is most suited to provide state of art power devices well into the foreseeable future.

i2技术的灵活性最适合于为可预见的未来提供最佳的功率器件。

Inception iterations in subsequent evolutions ( I2 and I3) were very short.

随后的演进（I2和I3）中的初始阶段非常短。

From the above we can realize that I2 treatment not only saves irrigation water, but also makes LUE reached an average maximum.

由此我们可以得出I2处理即节约了灌水量，又使桃树的LUE达到了全天平均最大值。

According to experiments, the properties of solvent may affect the action between solvent and I2, which is the reason why the colour of Iodine solution varies with the solvent.

通过一系列实验，探讨了溶剂的性质、溶液的浓度等因素对碘溶液颜色的影响，指出碘溶液的颜色与溶剂I2之间的电子给予电子接受作用密切相关。

In addition, it is expected that the improvement of rate capability and reversibility in such cells have the potential for revolutionizing the primary Li/ I2 cells.

另外可以预见，这种速率特性和可逆性能的提高对锂碘电池体系具有革命性的意义。

The order of I2/ I1 in 2 hours group is: Golgi> endoplasmic reticulum ( ER)> mitochondria/ lysosome;

I2/I1高低顺序2小时组：高尔基体>内质网>线粒体/溶酶体；

I can't have them sitting around idly until I2, waiting for I1 to end.

我不能让他们闲坐着直到I2的开始，等待I1的结束。
