But she noted that the United States and its partners in the P-Five-Plus-One group the five permanent U.N.Security Council member countries and Germany are pursuing a two-track strategy of incentives for Iranian nuclear cooperation and "consequences" if it fails to fulfill international nuclear obligations.

Enthalpy is just u plus p V.
你想要的任何地方。
-
So, du plus p dV is less than zero.
因此，du加上pdV需要小于零。
-
Sometimes you see this written when you see p orbitals, one is written as plus, one is written in minus.
有时候你们看ｐ轨道时会看到，一个写成正号一个写成负号。
-
Vdp So dH is just du plus p dV plus V dp.
所以dH等于du加上pdV再加上。
-
H=qp The u plus p V. Delta H is equal to q V.
括号里面的就是H，等于u+pv，Δ
-
Remember, we don't do a one-to-one correlation, because p x and p y are some linear combination of the m plus 1 and m minus 1 orbital.
记住，我们不需要把它们一一对应，因为ｐｘ和ｐｙ轨道是,ｍ等于正负１轨道的线性组合。
-
pV=RT p plus a over v bar squared times v bar minus b equals r t. All right if you take a equal to zero, these are the two parameters, a and b. If you take those two equal to zero you have p v is equal to r t.
我们就回到,也就是理想气体,状态方程,下面我们来看看,这个方程。
-
So we can have, if we have the final quantum number m equal plus 1 or minus 1, we're dealing with a p x or a p y orbital.
所以如果我们有,磁量子数ｍ等于正负１,我们讨论的就是ｐｘ或者ｐｙ轨道。
-
So again, looking at the shapes, now we're just combining two, we've got these two equal hybrid orbitals plus these 2 p orbitals here.
同样，我们看它的形状，现在我们仅仅结合两个轨道，我们得到这两个杂化轨道,和两个p轨道。
-
Remember the equation of state for Van der pV=nRT Waal's gas is not pV is equal to nRT, but p plus the attraction term.
记住范德瓦尔斯气体的状态,方程不是，而是p加上一个吸引项。
-
Normally I couldn't do that Vdp because this term would have p dV plus V dp, but we've specified the pressure is constant, so the dp part is zero.
一般情况下我不能这么写,因为这一项会包含pdV和，但是我们已经假定压强为常数，所以包含dp的部分等于零。
-
du external dV minus T surroundings dS is less than zero.
加上压强p，du，plus，p,乘以dV减去环境温度T乘以dS小于零。
-
V So it's minus T dV/dT at constant p, plus V.
负的T乘以恒定压强下dV/dT，再加上。
-
1 Similarly, if m is equal to either plus 1 or minus 1, py we would in turn call it the p y orbital, or the p x orbital.
类似的，如果m等于+1或，我们可以叫它，或者px轨道。
-
V Minus p2, V2. Minus p delta V. So the total work is the work from the left hand side plus the work on the right hand side, p1 V1- p2 V2 which is p1 V1 minus p2 V2.
负p2V2【w=-p2v2】，即负pΔ,所以全部的功就是,左边的功加上右边的功，等于。
