Above-mentioned housing, along with standpipe generation double vibrations, provides restoring torque by torsionspring, make housing and the wing put between carry out reciprocal relative motion, coil is along with wing pendulum is around fixed axis cutting magnet (magnetic induction line) and then generation current. Standpipe has very important effect in whole resource exploitation processing, and the standpipe as oil-gas transportation lifeline ensure that the exploitation of whole platform and carrying out smoothly of producing to a great extent.Consider that marine riser is the flexible structure with large deformation, due to the impact of the complicated factor such as change in location and vortex-induced vibration of platform, standpipe underwater stressed, distortion and geometric shape all need to carry out monitoring and make damage forecast, in case there is serious leakage accident.Wherein on the larger large scale eddy excited vibration be perpendicular on flow path direction of standpipe impact, when vortex-induced vibration occurs, standpipe can double vibrations in the direction in which, and vibrating the fatigue rupture caused is the main cause that standpipe destroys.The monitoring method of current employing be some is installed on standpipe monitoring instrument to monitor the kinetic characteristic of standpipe, obtain the dynamic characteristics of submerged riser system, reliability, fail safe by analysis.But monitoring instrument needs the supply of electric power, monitoring the data result that obtains also needs to feed back, so for the monitoring of deep sea vertical pipe, with cable carry out electric power, the transmission of data becomes relatively loaded down with trivial details.

En las malformaciones anorrectales, el área donde debe estar el ano puede estar recubierta de piel con varios centímetros de grosor o sólo una delgada membrana.
En las malformaciones anorrectales, la abertura del ano es estrecha, está cubierta de piel o está ausente. El recto es la bolsa del intestino grueso que contiene las heces antes de la defecación. El ano es la abertura que existe al final del tubo digestivo, por la cual las heces abandonan el organismo. La obstrucción intestinal es un bloqueo que impide completamente o altera de manera importante el tránsito del contenido intestinal. La mayoría de los bebés con atresia anal presentan algún tipo de conexión anómala (fístula) entre el ano y la uretra, la zona que se encuentra entre la uretra y el ano (el periné), la vagina o rara vez la vejiga. La atresia anal se produce habitualmente junto con otros defectos congénitos, como defectos de la columna vertebral, el corazón, los riñones y los miembros.
La atresia anal se produce cuando los intestinos no se desarrollan adecuadamente mientras el feto crece. Los bebés con atresia anal no pueden defecar normalmente después del nacimiento. Los bebés afectados también pueden tener fístula traqueoesofágica y atresia esofágica. Los bebés pueden desarrollar obstrucción intestinal. Los síntomas de la obstrucción intestinal en bebés suelen consistir en dolor, irritabilidad, vómito e hinchazón abdominal. Finalmente, si el defecto no se trata, se desarrolla una obstrucción intestinal.. Que tomar para dolor de rodilla
