冰緣區域 的英文怎麼說
中文拼音 [bīngyuánqūyù]
冰緣區域
英文
periglacial region-
Electrical field stress at the icicle tips is even stronger. at these areas, if the electric field across air gaps is high enough, corona discharges are initiated. this can lead to the development of local arcs across the air gaps causing a substantial increase in leakage current and a concomitant melting of ice
空氣間隙的存在使覆冰絕緣子表面的電場分佈發生了明顯畸變，間隙上承受了非常高的電壓，這使得冰凌尖端的電場變得相當強，一旦電場達到了電暈的起始電場，局部放電就在這一區域發生，進而產生局部電弧並逐漸發展成整串的閃絡，泄漏電流迅速增大，同時伴隨著冰的融化。Because of the low temperature there, water vapour condenses into small, clear crystals. a layer of glossy cirrus forms which drifts out from the centre of the tropical cyclone because of divergence at that level. so, when the outer edge of a tropical cyclone reaches hong kong, we can see cirrus high in the sky
熱帶氣旋強烈的上升氣流會把潮濕的空氣帶到近五六千公尺以上的高空，由於溫度很低，水氣結成了透明的小冰粒，形成像絹絲一樣發光的雲彩-捲雲，這些在高層輻散流場區域的捲雲，會從熱帶氣旋中心向外流出，所以當香港還是位於熱帶氣旋邊緣時，我們便已看到那些在熱帶氣旋外圍的捲雲，並稱為臺母。
