The height of central part of the round cambered surface is equal or higher than the one of ring- shaped bulge. When the horizontal top side of internal cavity of encapsulation mold is pressed down to the heat sink so as to produce a deformation, the cambered surface can not be pressed to oppress the subjacent metal line, and the ring-shaped bulge can also prevent mold-overflow.

该散热片，适用于封装制程，具有一圆形弧面板部，并且其圆形弧面板部的中央是高于或等于环状凸起的高度；如此一来，当封胶模具内模穴的水平顶面下压至散热片上而使其产生变形时，圆形弧面板部就不会压迫到下方的金属线，而环状凸起同样也可发挥防止溢胶的功能。

Leaves simple, usually alternate, rarely opposite or verticillate, sometimes crowded at apices of branches; stipules usually small and caducous, sometimes larger, leaflike and persistent, rarely absent; petiole generally present, sometimes with apex 2-glandular and/or with additional glands along petiole length; leaf blade usually pinnate-veined, sometimes 3-5-veined from base or palmate-veined, with or without pellucid dots or lines, sometimes with a pair of glands at junction of blade and petiole, margin entire or toothed, teeth glandular or not. Inflorescences axillary, terminal, or cauliflorous, of various forms: racemose, spicate, cymose, corymbose, or paniculate, sometimes flowers fasciculate, or solitary; pedicels often articulate; bracts and bracteoles usually small to minute.

This paper reviewed its pathogenesis, forms, clinical manifestations, differential diagnosis, treatment and prognosis. Here a case of neonatal hypophosphatasia is reported. This baby was female (30 minutes old). Prenatal ultrasound showed disproportionate biparietal diameter and long bones of limbs in the baby. After birth, she presented with obvious craniomalacia, respiratory distress and cyanosis. Serum alkaline phosphatase level was significantly reduced. Both X-ray and autopsy showed extremely insufficient skeletal mineralization. Four days later she died of respiratory failure.
