Uniaxial compressive strength (UCS) and the static Young’s modulus (Es) are fundamental parameters for effective design of engineering structures in a rock mass environment. Determining these two laboratory is time-consuming costly, results may be inappropriate if testing process not properly executed. Therefore, most researchers prefer alternative methods to estimate parameters. This work evaluates thermal effect on physical, chemical, mechanical properties marble rock, proposes prediction...
A recruiting rate (krc) of 0.1–5 s–1 has been proposed as the criterion for super-resolution spontaneously blinking rhodamines. Accurate prediction rhodamines is very important developing However, far we know, there no reliable theoretical method to predict krc. Herein, meticulously investigated effect intermolecular hydrogen bonds on spirocyclization reactions Moreover, a descriptor (ΔEC–T) was reliably assess ΔEC–T quantified ring-opening energy barrier reactions. robust linear correlation...
Deep mining near faults may easily cause rock bursts, which seriously threaten safety. Based on the engineering background of deep fault in Yima coalfield, by collecting burst events that happened during mining, correlation between structure and time‐space features was analyzed. The results show accounts for 84% coalfield at 600 m 93% area within 1000 from F16 fault. risk is positively correlated with depth negatively distance fault, frequency intensity increase significantly. Rock occurs...
To explore the differences in fine root characteristics and rhizosphere environment of male female Idesia polycarpa Maxim at different stages, 7-year-old I. were used as plant materials. The measured with a scanner, soil was collected flowering stage (May), fruit accumulation (July), maturity (October). In addition, this study analyzed nutrient these conditions stages. At same time, Illumine high-throughput sequencing technology gas chromatography–tandem mass spectrometry (GC–MS) to analyze...
In this study, a uniaxial impact compression test was performed on coal samples with length‐to‐diameter ( L / D ) ratios of 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1 using Φ 50 mm split Hopkinson pressure bar (SHPB) system. This study researched the stress uniformity deformation behavior different during dynamic compression, defined equilibrium coefficient ξ , proposed new method for determining whether sample meets hypothesis, obtained critical ratio 0.6 optimal 0.3 or 0.4 to obtain...
The weakly cemented sandstone is widely distributed in the Western Mining Area, which mainly formed by mineral grains and minerals through compaction cementation. To study influence of grain size on mechanical properties acoustic emission (AE) characteristics sandstone, uniaxial compression Brazilian splitting AE tests were carried out four specimens with different sizes. physical properties, behaviors, under two conditions analyzed, microfailure mechanism was investigated. results show that...
Coal samples having the same diameter (50 mm) and different length-diameter ratios (l/d), i.e., 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0 were tested under dynamic uniaxial impact compression using Split Hopkinson Pressure Bar (SHPB) experimental system. This study evaluates: (a) The effects of l/d on energy consumption law fractal characteristics coal crushing; (b) stress balance dissipation; (c) density crushing. findings are as follows: (1) show similar stress–strain curve shapes in stages...
Maxim is an emerging oil plant species. Understanding its microecological characteristics and internal mechanisms can serve as a basis for field management the screening application of growth-promoting bacteria during growth phase young trees. This study used three-year-old
Phosphorus (P) is crucial for tree growth and development, it significantly influences the rhizosphere microbial community. However, effects of phosphorus addition on communities in soil Idesia polycarpa remain understudied. In this study, two-year-old “Yuji” seedlings were used to investigate fertilization at four different levels 0 g (control, CK), 0.92 (low phosphorus, LP), 1.83 (medium MP), 2.75 (high HP) per plant. The fertilizers applied every 40 days over 120 days. MiSeq...

(P. vulgaris), providing provide basic data support for protecting its wild germplasm resources. The stems, leaves, flowers, ears seeds different populations P. were measured reveal among within vulgaris, a scientific basis protection, utilization collection Methods: Variance analysis, coefficient multiple comparison cluster analysis...
At the present time, it is considered to be of major significance study gas emission law and stability controls coal bodies in deeply buried high‐gas seams. For this reason, view specific problems emissions caused by unstable rib spalling mine walls, comprehensive research methods were adopted study, order conduct an in‐depth examination micropore structure parameters, desorption, diffusion laws, levels. The results showed that development degree pores above micropores, as well small soft...
A virtual crack vector model is proposed in this paper to simulate the branched propagation and simplify its calculation of energy release rate. An gradient fracture criterion constructed based on model.
