Principal component analysis shows that the comprehensive effect was the best with PDJ treatment, and high concentration PDJ has better effect than low concentration PDJ, while the rooting powder treatment was less effective than the control treatment.

So as to improve grains yield. Of all teatments, 10mg/ kg PDJ spraying treatment with 16. 7% increase of the yield per stem is significance;

促进干物质的累积，从而提高了谷粒产量其中10mg／kgPDJ喷雾处理，提高了单株产量16.7%，差异显著；

05mg/ kg PDJ root soaking with 20. 8% increase is very significance.

05mg/kgPDJ浸根处理，提高了单株产量20.8%，差异极显著。

The results indicated PDJ could improve the vigor of root system and NRA of leaves, increase chlorophyll and soluble protein content, thus laying a better physiological foundation for high yield.

结果表明，二氢茉莉酸丙酯提高了根系活力和叶片硝酸还原酶活性（NRA），增加叶绿素含量和可溶性蛋白含量，从而为高产奠定了良好的生理基础。

Significant negative correlation was found between D/ R PDV, D/ R PSV and interseptal thickness, left ventricular mass index in hypertensive patients.

高血压病人的D／R PDV、D／R PSV与室间隔厚度及左室重量指数呈显著负相关。

The linear PDV discriminant model of STRs with high gene frequency was established, and owned good separability and stability, the prediction rate of 100%.

用PDV法建立了高基因频率STR线性判别模型，具有良好的分离度和稳定性，对预测集样本的判别完全正确。

It suggested the immunization effectivity and antibody persistence of YDV and PDV could maintain at least 8 years and 9 years respectively.

提示YDV的免疫效果及抗体持久性至少可维持8年，PDV至少可维持9年。

So it's, this is just the integral pdv And it's an ideal gas, isothermal, right.

从一点到二点的，的积分。，from，one，to，two，of，p，dV。，这是理想气体，恒温过程，好的。

With the Badain Jaran Desert experiment, both the new developed model and the PdV model were used to calculate surface evaporation.

利用巴丹吉林沙漠的试验数据，将新建立的模型应用于计算该试验场地的蒸发通量，并对比新模型计算结果与PdV理论计算结果之间的差异。

Pdv It's an isothermal expansion, so dw is just negative p dV.

因此dw等于负，这就是。
