Let {X（t）, t ≥ 0} be a standard（zero-mean, unit-variance） stationary Gaussian process with correlation function r（·） and continuous sample paths. In this paper, we consider the maxima M（T） = max{X（t）, t∈ [0, T ]} with random index TT, where TT /T converges to a non-degenerate distribution or to a positive random variable in probability, and show that the limit distribution of M（TT） exists under some additional conditions related to the correlation function r（·）.

In this paper, we give an upper estimate for the Clarke-Rockafellar directional derivatives of a function of the form f - g, where f, g are max-functions defined by locally Lipschitz but not necessarily differentiable functions on a closed convex set in a Euclidean space. As an application, we give a sufficient condition for f - g to have an error bound.

Amine-based solvent for CO_2 absorption and its impact on carbon steel corrosion: A perspective review

The 2nd International Conference on Applied Mechanics and Mechanical Engineering(ICAMME 2011)

作者： Chen bingyao Inner Mongolia University Science and Technology

Constant–current soft starting on induction motor based on fuzzy control is characterized as low system overshoot, fast response and relative stable starting process, so it can better solve the shortcomings existed in traditional methods and PID control methods, and improve the whole system reliabilityIn this article a special fuzzy control is adopted to complete the starting process, in which thyristor is the main current components and MCU is the control coreAnd this makes the entire starting process out of current impact.

Based on the demand on efficient axial-flow blast with low noise and energy saving, a blade was designed through the application of the unequal work distribution principle and the exponential twisted camber was used to shape blades. Then, the hydrodynamic characteristics of blades were studied and the strengths and vibrations of blades and hydro-dynamic noise of blast were analyzed. Furthermore, the software of optimization design of axial-flow blast was developed. Finally, the HMF-T40No.20 axial-flow blast used in large textile conditioner system of cotton spinning industry was designed, which could meet the required total safety and environmental requirements as the corresponding test demonstrates. The study is beneficial to designing axial-flow blast.

背景:运动是老年人肌少性肥胖防治与管理的重要策略,但目前缺乏对于老年人肌少性肥胖的精准个性化运动处方的探索与研究。目的:综述老年人肌少性肥胖的串联机制以及不同运动方式对老年肌少性肥胖患者的干预效果,以期为老年人肌少性肥胖运动处方的制定提供理论与实践指导。方法:以英文检索词“sarcopenic obesity,sarcopenic adiposity,aging,sport,exercise,exercise intervention,exercise prescription,resistant training,aerobic training,combination training,muscle strength,muscle mass,physical activity”;中文检索词“肌少性肥胖,少肌性肥胖,肥胖性肌少症,老年人,运动,运动干预,运动处方,抗阻运动,有氧运动,联合运动,肌肉力量,肌肉质量,身体活动”,分别检索PubMed、Web of Science、中国知网、维普、万方数据库,严格按照纳入与排除标准,对纳入的85篇文献进行综述分析。结果与结论:①抗阻运动仍然是预防与缓解老年人肌少性肥胖的有效运动方式,抗阻运动在改善与提高骨骼肌质量、肌肉力量与耐力以及身体功能等方面效果更为显著,但在实际应用中应循序渐进,逐渐增加至中高强度。②有氧运动也是防治、减缓肌少性肥胖进程的重要干预方法,其在改善老年肌少性肥胖患者心肺耐力、降低体脂百分比以及减少内脏脂肪面积等方面更为有效。③有氧-抗阻联合运动将有氧运动与抗阻运动的优势相结合,可以更好地改善身体成分,同时在降低心血管疾病危险因素方面有更好的效果。联合运动在一定程度上优于单一的运动方式。
