With regards to the engineering practice of concrete gate frusta in Yangjialing Spillway, the mechanical properties of concrete gate frusta have been experimentally researched.
This paper intends to report three experimentally simple preparations of naphthoquinone, hydroquinone and the corresponding mixed quinhydrone,all redox chemistry being carried out in the solid state.
HALS are experimentally used in PVC films in this study.It is shown that thermostabilization and photostabilization functions of HALS are similar to those of benzophenone in PVC.
First the good news, when they're behaving themselves it is extremely easy to describe their behavior theoretically, experimentally and mathematically.
