A touch control method and a touch control electronic apparatus are provided. In a plane perpendicular to an axis of the guide shaft, the two sloped sides are disposed such that a line passing through both the axis of the guide shaft and an intersection of two tangent lines from contact portions in which the two sloped sides contact the outer circumferential surface of the guide shaft diagonally intersects a line extending along a plane of the nozzle surface. The atomic events corresponding to the user activities are classified into tasks based on similarity of the queries within the user activities. Azimuthal spatial transform filtering is applied to produce data representing a received acoustic pulse of the selected azimuthal borehole mode. Thus, the extended 5\u2032-UTR AS mRNA species is a mechanism for regulating AS expression and NO production, and provides a target for the treatment of pathophysiological conditions associated with vascular endothelial dysfunction and characterized by impairment of NO production, such as heart failure, hypertension, hypercholesterolemia, atherosclerosis, and diabetes. 07 ccg or more after calcination at 600\xb0 C.
