The low-pressure andalusite sequence metamorphic belt includes biotite zone, garnet zone, staurolite zone, staurolite-andalusite zone, sillimanite zone and cordierite-sillimanite zone. It is calculated that the P-T conditions are 445～550℃, 0.2～0.6GPa for biotite zone, 480～566℃, 0.54± 0.22GPa for the garnet zone, 601±20℃, 0.8±0.25GPa for the staurolite zone, 540±20℃, 0.32± 0.05GPa for the staurolite-andalusite zone, 640℃, 0.43GPa for sillimanite zone, 740～800℃, 0.4～0.7GPa for the cordierite-sillimanite zone.

黑云母带的变质条件估计在445～550℃、压力在0.2～0.6GPa范围变化；石榴石带温度在480～566℃、压力在0.54±0.22GPa的范围；十字石带范围为601±20℃、0.8±0.25GPa；十字石-红柱石带为540±20℃、0.32±0.05GPa，而利632.4℃、0.785GPa，这个值不是红柱石的稳定范围，这可能是其早期中压变质条件；矽线石带的条件640℃、0.43GPa左右，由于其石榴石中有蓝晶石包体，因此其早期也可能有中压条件的变质；堇青石-夕线石带范围大致为740～800℃、0.4～0.7GPa之间。

1 A comprehensive protection of the old city must be taken into consideration, which exists in the following ten scopes: protection of the water system of rivers and lakes, protection of the traditional axis, protection of the Imperial City, protection of the arches in the shape of 凸 in the old city, protection of roads, streets, alleys, small lanes known by their Manchu Hutong, protection of the height of traditional-style buildings, protection of the urban scenical lines, protection of the symmetrical structure on the street, protection of the colors of constructures, and protection of ancient and famous trees.

6.0.1 必须从整体上考虑北京旧城的保护，具体体现在历史河湖水系、传统中轴线、皇城、旧城"凸"字型城廓、道路及街巷胡同、建筑高度、城市景观线、街道对景、建筑色彩、古树名木十个层面的内容。

This text has analyzed the common malfunction of the asynchronous motor at first. And then it, which is based on symmetrical weight theory, has drawn accurate criterion of the trouble of the motor, confirmed the protective measures of different troubles. Finally, it has realized kinds of protection functions, such as short-circuit protection, rotate-stop protection, over-heat protection, negative current protection, zero current protection, low-voltage protection, over-voltage protection, overlong start-up time protection, frequent start-up protection, lock protection of electric leakage and so on.

本文首先分析了异步电动机的常见故障，以对称分量法为依据，采用检测过流幅值、负序电流、零序电流的方法，得出了电动机故障的准确判据，确定了各种故障的保护措施，对电动机实现了短路、堵转、过热、负序电流、零序电流、低电压、过电压、启动时间过长、频繁启动、漏电闭锁等保护功能。
