In this work,through the self-developed setup for in situ electrochemical tests,the corrosion behavior of 13 Cr stainless steel under the combined effect of stress and crevice in high pressure CO_(2)/O_(2)environment was *** results show that 13 Cr stainless steel presents a self-passivation *** the action of stress,the anodic dissolution process of steel inside crevice is *** is a galvanic effect between the stressed steel inside crevice and the unstressed steel outside *** applied stress reduces the induction stage of crevice corrosion and induces a larger galvanic current,i.e.,the applied stress promotes the development of crevice ***,adding 0.1 MPa O_(2)is conducive to forming a more stable passive film but causes a greater galvanic effect.

Helix unwinding in ferroelectric liquid crystals induced by an electric field is theoretically studied on the basis of the continuum theory. By applying a weak electric field tilted to the smectic layers, the contribution of the dielectric interaction energy density to the total free energy density is increased. Approximation methods are used to calculate the free energy for different tilt angles between the electric field and the smectic layers. The obtained results suggest selecting the optimal number of pitches in the film that matches to the minimum of the free energy.

The power plant of planning construction Shawan hydropower station was planned in the toe area of the right bank *** scale cracks with maximum length over 20 m and downward displacement over 1.0 m occurred in the Quaternary accumulation of the middle part of the slope during excavating site for the power plant,and as a result the excavation has to be stopped.A monitor net was placed on the slope and the monitor result indicated that a slide mass has been *** with topography analysis,geological investigation i.e.,borehole exploration,geophysical investigation,it can be concluded that the slope where the power plant located is an overlooked giant ancient landslide during pre-stage investigation for site of hydropower plant,and the landslide is partially *** results indicated that the deformation of the slide is not even,the displacement of the head area is mainly vertical component,and the displacement of the toe area is mainly horizontal *** slide was induced by lots of drainage from No.2 access tunnel,the successive rainfall would accelerate the deformation, and the excavation of new provincial highway in toe area had a crucial effect on local deformation. The slide mass had experienced rainstorm seasons and it did not present severe deformation,thus the slide mass could be stable if drainage system including surface and underground is *** risk of blocking up Muli River is *** conclusions presented above have been verified in practice.

In response to a suggestion that the large meander of the Kuroshio is a good predictor of droughtsin the Changjiang River Valley, it is argued that more recent inceptions of the meander lend statisticalweigh to the belief that the large meander is itself a consequence of E1 Nino, and hence of the SouthernOscillation. The meander usually lags. Thus, if the meander reliably predicts droughts, the Tahiti componentof the Southern Oscillation will usually give six months’ extra warning.

The paper provides an overview of geometric solutions of marking all types of serpentine by the method of internal circular curve in designing forest roads directly in the field. The main objective of presenting this original method for marking all serpentine types in one place is to show similarities and differences in marking different types of serpentine, and identify opportunities for further research of this type. The method is based on the establishment of the minimum number of elements necessary to mark the serpentine on the forest roads and other budget elements and their design in the field. By using this method, construction errors or the number of attempts of serpentine marking are reduced, which increases the effects of design compared to the ones reached by the previous method of marking the serpentine on forest roads.

In the article published in the Asian Journal ofAndrology, Esteves et al.1 report on the results of a reasonably large （365） retrospective series of patients with nonobstructive azoospermia （NOA） who had sperm collected by microscopically assisted microdissection （microTESE） for intracytoplasmic sperm injection （ICSI）. The results from NOA patients are compared with previously published data from a group of men with obstructive azoospermia collected during the same time frame. In addition, as is standard of care, the couples were offered ICSI with donor sperm if the microTESE procedure failed to yield sperm, providing a group from the same cohort who had ejaculated sperm used for ICSI.
