In medicine, an external cause is a reason for the existence of a medical condition which can be associated with a specific object or acute process that was caused by something outside the body. Such causes are classified as "E codes" in ICD 9.

Method for constructing non-penetrated jointed rock mass damage constitutive models under plane compressive shear stress

The invention relates to a method for constructing non-penetrated jointed rock mass damage constitutive models under a plane compressive shear stress. The method comprises the following steps of: associating additional strain energy increments caused by crack in fracture mechanics with damage mechanics strain energy burst sizes, and importing the additional strain energy increments and the damagemechanics strain energy burst sizes into a non-penetrated crack extension criterion so as to put forward an external force-considered calculation formula for jointed rock mass damage variables; and finally obtaining a crack parameters (internal causes) and stress conditions (external causes)-considered non-penetrated jointed rock mass damage tensor calculation method, so as to establish a corresponding damage constitutive model. According to the method, the condition of considering external force is suitable for influences caused to rock mass damage variables by common stress states (not comprising positive stress and comprising shearing stress, and suitable for single-axis or double-axis stress states only comprising positive stresses), so that the defect that only rock damage variable calculation under double-axis pressure, namely, influences caused by rock damage variables by confining pressure , is considered in variable calculation of rock mass damages caused to cracks by externalforce in the prior art is overcome.

Layered protecting configuration of outdoor low-voltage distribution area active compensation device and fault handling method

The invention provides a layered protecting configuration of an outdoor low-voltage distribution area active compensation device and a fault handling method. The protecting configuration is composed of three layers, namely a component grade, a device grade and a system grade. According to the fault handling method, according to different layers of the layered protecting configuration of the outdoor low-voltage distribution area active compensation device, different protecting signal handling modes and different fault handling modes are correspondingly adopted. The fault handling modes are composed of a mode for instantaneous recoverable faults and a mode for unrecoverable faults. After a fault output causes IGBT pulse blocking or grid-connecting switch tripping, a fault output signal is acquired in real time. When the fault output signal is eliminated, the instantaneous recoverable fault which is caused by an external reason is determined. When IGBT pulse blocking occurs, pulse blocking is eliminated after one-minute time delay. When grid-connecting switch tripping occurs, the grid-connecting switch is automatically switched on after 10-minute time delay, and the device operates again. According to the layered protecting configuration, software analysis is combined with hardware determination, and high complexity in operation of a distribution network is sufficiently considered, thereby effectively improving operation reliability of the outdoor low-voltage distribution area active compensation device.
