The bidirectional reflectance distribution function (BRDF) can effectively characterize the reflectance properties of a target, which can be used to correct infrared remote sensing data and improve the accuracy of remote sensing measurements. When the surface temperature changes, the reflectance characteristics of the target usually change, and it is necessary to carry out BRDF measurements under variable temperature conditions. In this paper, a variable-temperature infrared BRDF measurement system based on a robotic arm is developed to realize high-resolution wide-temperature region measurement of BRDF.

WS-C is produced from a hydrothermal reaction, in which WS nano-sheets are coated with carbon, using glucose as the carbon source. In order to investigate the tribological properties of WS-C as a lubricant additive, WS-C was modified by surfactant Span80, and friction tests were carried out on an MRS-10A four-ball friction and wear tester. The results show that Span80 can promote the dispersibility of WS-C effectively in base oil.

Objective: To evaluate the influence of anisodamine (Ani) on restoration of spontaneous circulation (ROSC) and cardiopulmonary resuscitation (CPR) rate in a randomized, blinded experimental study so as to explore a new treatment for CPR.
Methods: Forty-five Sprague-Dawley (SD) rats were randomized to three groups: control group (0.9% normal saline), epinephrine (Epi) group and Epi plus Ani group (combined group), 15 rats in each group.
