چکیده
Based on the data set of AVHRR GIMMS, TERRA/AQUA MODIS NDVI, and climate from 1982 to 2018, CASA model, GIS spatial analysis, mathematical statistics were used study changing law in category time space, distribution, correlativity between NPP meteorological factors sandy land China's Seasonal Freezing-Thawing Typical Region. The results showed that average annual value vegetation growing season 2018 fluctuated 217.65-356.61 gC/m2a, showing an obvious seasonality a significant increase. distribution near 37a is significantly different. There are seasonal differences responses temperature, precipitation, wind speed, evaporation, other different regions. increase cover Region controlled by regional atmospheric circulation human dynamics.

Ultrasonic monitoring of fish thawing process optimal time of thawing and effect of freezing/thawing.
INTRODUCTION Fish quality is traditionally controlled by chemical and microbiological analysis. The non-destructive control presents an enormous professional interest thanks to the technical contribution and precision of the analysis to which it leads. This paper presents the results obtained from a characterisation of fish thaw-ing process by the ultrasonic technique, with monitoring thermal p...
