To investigate the clinical differentiation of spleen-deficiency pattern (SDP), a group of symptoms and signs defined in terms of Traditional Chinese Medicine for its clinical practice.

The novel cyanide detoxification and resource utilization of cyanide tailings were treated sequentially by the oxidation-reduction roasting. Through a series of conditional experiments, the oxidation roasting realized the content of cyanide decrease to < 0.04 mg/kg (detection limit) with the removal rate reached to 99.99% at the optimum conditions. The reduction roasting realized the main mineral hematite transformed to magnetite and recycled the iron concentrate from the cyanide tailings with iron grade of 59.21% and iron recovery of 89.57%. The migration and transformation paths and decomposition products of cyanide during oxidative degradation process were investigated by the hexacyanoferrate reagents decomposition with the real-time concentration of CO2, XRD and FT-IR. The hexacyanoferrate decomposition reactions were complex, and divided into three stages, such as the room temperature-350 ℃, 350 ℃− 550 ℃, 550 ℃− 800 ℃ respectively. The transformation paths and decomposition products iron-cyanide complex were mainly as follows: K4Fe(CN)6or K3Fe(CN)6was oxidized and decomposed into CNO-, and further decomposed into CO3-by the roasting temperature increasing.

Downhole temperature and pressure data are crucial information to help us understand the fluid flow dynamics in the reservoir. With the advancement of downhole monitoring technology, high-precision and high-resolution monitoring instruments facilitate qualitative and quantitative utilization of transient downhole temperature and pressure data in monitoring applications. The distributed temperature sensors (DTSs) overcome the limitations of traditional monitoring techniques and achieve real-time temperature monitoring in complex downhole conditions. However, the physical phenomena and response mechanisms hidden in the temperature data obtained by (DTSs) in transient, multilayered combined production and two-phase gas wells have not been thoroughly studied yet.
