Dialkylamine, which is an e-donor, was introduced at the C(4') or C(7) positions in 3HF resulting in similar ESICT/ESIPT dual emission. Even the net dipole moment, the orientation of which is affected by the CT effect, is expected different. Dialkylamine attached at both C(4') and C(7) positions in 3HF, of which the net dipole moment may be associated with the interplay between two charge-transfer systems, displayed different photo behaviors.

Three short geomagnetic excursions, the Go thenburg, Mono Lake and Mungo in the Brunhes Positive Polarity period, were revealed based on the studies of magnetostratigraphy, susceptibility and δ^18O of sediments in core WP 92-5 from the central temperature area of the Western Pacific Warm Pool, and the ages of them are 12.1--11.3 kaBP, 25.0--24.0 kaBP, and 31.0--28.0 kaBP respectively. Furthermore, the Younger Dryas and Heinrich cold events were also discovered in this core by the susceptibility record.

研究表明，煤炭浮选非极性捕收剂对起泡剂的起泡性能具有显著的影响，具体效果与化学组成、浓度及配比有关，这一点对于煤炭浮选用药具有重要的意义。

Treatment under mild condition with solvent of lower polarity was in favor of keeping the molecular structure and properties such as water-solubility, gelatination, etc. Acetyl groups were partially eliminated when purified by Pb2 method, leading to increased crystallinity and glass temperature, which resulted in losts of water-solubility and gelatinability. Owing to the slight oxidative degradation with H2O2 method, the changes of chain size and some functional groups of KGM molecule led to decrease of viscosity and excessive swelling rate.

采用温和条件及低极性溶剂有利於保持KGM本身的分子结构以及水溶性、凝胶性等性能；而Pb2法由於部分脱去了KGM的乙酰基，导致结晶度变大，玻璃化温度升高，最终失去水溶性和凝胶性；H2O2法则由於对KGM造成了氧化降解，也改变了分子链的大小以及部分基团，从而导致粘度降低以及溶涨速度较快。
