If you think about AB 32, to roll back our greenhouse gases to the 1990 level, or if it is the Million Solar Roof Initiative, the Low-Carbon Fuel Standard, the Renewable Energy Standard, the Green Building Initiative, the Hydrogen Highway, and the list goes on and on of the kind of things that we have done.

这里我们会想到AB32政策会把二氧化碳的排放降低到1990年的水平；或者"百万太阳能屋顶"鼓励政策，"低炭燃料"标准，可持续能源标准，"绿色建筑"倡议，"氢燃料高速公路"等等等等。

Using the main result, we also obtain a simple criterion to check if a given C(superscript *)-algebra A is Abelian, that is, A is Abelian if and only for any two positive elements a, b∈A, there is a'∈A such that ab=ba'.

利用文中的主要结论，还得到了判断C-代数A是交换一个简单条件，即A是交换的当且仅当对A中的任何两个正元a，b存在a'∈A使得ab=ba'。

Using the main result, we also obtain a simple criterion to check if a given mathrm C^*-algebra A is Abelian, that is, A is Abelian if and only for any two positive elements a, bin A, there is a'in A such that ab=ba'.

利用文中的主要结论，还得到了判断 mathrm C^*-代数 A 是交换一个简单条件，即 A 是交换的当且仅当对 A 中的任何两个正元 a， b 存在 a'in A 使得 ab=ba'。

Suppose G is a finite group, then QG is a semisimple Q-algera, obviously ZG is a Z-order of QG,we denote the maximal Z-order by ?.If G is not abelian, it is not an easy thing to determine г; if G is an abelian group, then QG is isomorphic to the direct sum of a finite number of number fields, and r is the direct sum of these rings of algebraic integers of those number fields, but which elements of QG belong to r is not clear.

设G是一个有限群，那么QG是一个半单代数，ZG是QG的一个Z-序，设Γ是QG的一个极大Z-序，当G是一个非交换群时，Γ的求解是困难的问题；当G是一个交换群时，QG同构于有限多个数域的直和，Γ相应的就是各数域代数整数环的直和，但Γ具体是QG中那些元素不清楚。

If you have the ability, if you have such a demand ...

如果你有这样的能力，如果你有这样的需求。。。

Even those who should abjure their errors were condemned, if men, to die by the sword; if women, to be buried alive.

因此，如果这种类型的异常是不可避免的如果克隆人类必须继续下去。

There is something exasperating about this movement, something abortively melancholy about it, as if it had been written in lava, as if it had the color of lead and milk mixed.

西尔维斯特的脑袋偏向一侧，像个拍卖商。

If one supposes, as I think is reasonable, that if one is talking about physicists at a top twenty-five research university, one is not talking about people who are two standard deviations above the mean.

我们假设，我觉得这是合理的，比方说在最好的25所大学里的物理学家们，这些人恐怕不是高于均值两个标准差，甚至都不止三个标准差。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
