TL;DR: In this paper, a polyether ester copolymer with a high-content ethylene glycol chain segment is provided, which is suitable for the preparation method of large-scale industrial production and is stable, easy to control, mild in condition, economic and environment-friendly.

TL;DR: In this article, a three-freedom-degree secondary mirror adjusting device is proposed, where a secondary mirror is mounted on the secondary mirror rack and a lens cone is arranged on the outer side of the secondary rack in a sleeving manner, and a central line-system optical axis of the lens cone overlaps with the central line of the primary mirror lens.

TL;DR: In this paper, a method for quantitative determination of regeneration capability of 1,5-ribulose diphosphate was proposed, which comprises the following steps: selecting the second, the third and the fourth completely spread leaves, performing non-destructive determination on apparent photosynthesis rate, taking a mean value of three leaves to represent the apparent photoynthesis rate PN of the plant; then taking the leave which has measured apparent photosynthetic rate, shearing the leave and fully mixing the leave, taking 0.1 g of the material for enzyme liquid extraction; respectively

TL;DR: In this paper, a novel method to remove impurity silicon from aluminum melt by the addition of K2TiF6 was studied, where the mechanism for silicon removal is the formation and sedimentation of Ti(Al 1-x,6)3 phase and the removal efficiency is mostly decided by the solubility of silicon in TiAl3 phase, which increases with the increasing of the initial silicon concentration in aluminum melt.

TL;DR: Two standard smoothing functions are applied to interpolated and non-interpolated ( original) diatom data, expressed as three statistical indices (detrended correspondence analysis (DCA), Hill’s diversity index N2 (HDI) and correspondence analysis), using different sliding-window sizes and the two-standard-deviation range of dates for each sample.
