Abstract: A thermal resistance heater with a thermal conductive shell that is used to contact with tumor tissues and conduct heat therefor is provided. A thermal resistance is disposed inside the thermal conductive shell and is self-heated via current. The thermal energy is converted from the electrical energy according to Joule's Law. The heater includes a heat radiator disposed inside the shell and is used to disperse the heat generated by the thermal resistance and conduct the heat to the shell evenly. A thermal-conduction compensation arm and the heat radiator are contacted for achieving that a temperature of the shell is the same with a specific place or an error there-between is within a threshold. A temperature sensor is used to obtain a surface average temperature of the conductive shell by collecting temperatures over the thermal-conduction compensation arm.

Abstract: The present invention relates to a catalyst for aminating a polyether polyol and preparation method thereof and a method of preparing a polyetheramine using the catalyst. The catalyst has active components and a carrier. The active components are Ni, Cu, and Pd. The method of preparing the catalyst comprises the following steps: using a metal solution or a metal melt impregnated carrier, obtaining a catalyst precursor; and drying and calcinating the obtained catalyst precursor, so as to obtain a catalyst. By introducing the active component Pd in the catalyst, the present invention clearly improves selectivity of an amination catalyst with respect to a preaminated product, and increases raw material conversion rate.
