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.

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。
-
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。

Senior diplomats of the five permanent U.N.Security Council member countries and Germany -the P-Five-plus-One-are to meet at the end of this month in Geneva with Iran's nuclear negotiator to review Tehran's overall response to their offer of incentives for it to curb enrichment and return to negotiations.

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。
-
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。
-
Enthalpy is just u plus p V.
你想要的任何地方。
-
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。
-
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。
-
So, du plus p dV is less than zero.
因此，du加上pdV需要小于零。
-
Vdp So dH is just du plus p dV plus V dp.
所以dH等于du加上pdV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。
-
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
-
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。
