6) PI index 生产力指数(PI指数)补充资料:生产关系适应生产力状况的规律 以生产方式矛盾运动中生产力和生产关系的相互作用为内容的、决定社会发展的最基本的客观规律。亦称生产力与生产关系矛盾运动规律。 生产关系适应生产力状况的规律是马克思和恩格斯发现的。19世纪40年代,他们在《德意志意识形态》、《哲学的贫困...
In this paper, a mathematical model is proposed to investigate the effect of nonlinear flow mechanisms on productivity-index (PI) behavior in hydraulically fractured reservoirs during steady-state condition. This approach focuses on the fact that PI approaches a constant value at a certain time, ...

We investigate the impact of nonlinearity of high and low velocity flows on the well productivity index (PI). Experimental data shows the departure from the linear Darcy relation for high and low velocities. High-velocity (post-Darcy) flow occurring near wells and fractures is described by Forchh...
This study examined the feasibility of adapting a soil-based productivity index (PI) to predict root distribution in Missouri oak (Quercus spp.) stands. Roots and soil were sampled to 150 cm in 58 plots in the Missouri Ozarks and Missouri River hills. Soil pH, bulk density, and moisture ...
The model is shown to give good predictions and promises to be an improvement over the former productivity index (PI) because it accounts for weather and cropping conditions. It also promises to give more reliable results than the currently used insufficient models which consider only soil water ...
