It is formed of alternating layers of aluminium oxide and sodium ions. In 1967 researchers at the Ford Motor Company discovered that it conducts these ions as though it were a liquid.

钠β-氧化铝是由氧化铝和钠离子的交替层组成。1967年，福特汽车公司的研究人员发现，这些导电的离子好像是液体一样。

So it needs improving or alternating urgently. Some good germplasms for rootstocks for citrus have been picked out and introdcted into. Some somatic hybrids used as rootstocks have been selected through somatoplasm fusion. Some methods in early identification on stability of inherence and copatiblity and dwarf are explored, and they need improving. Rootstocks having some virtues have been selected, but they cannot take the leading place of trifoliate orange. The research method that the rootstocks are only compared with each other should be altered into that the rootstocks and given control measures or environmental conductions are connected to make the rootstocks compared with each other.

在砧木选择研究进展上，中国调查出和引进了一些优良的柑橘砧木种质资源，通过体细胞融合选育出一些可作为柑橘砧木的柑橘体细胞杂种资源；在柑橘砧木资源的遗传稳定性、嫁接亲和性和矮化性等早期鉴定上，探索出一些有待完善的鉴定方法；在砧木选择上，选出一些具有某些优点的砧木，但尚不能冲击枳砧的主导地位，并且选择研究方法有必要把现行单纯的砧木比较改为与砧木种类、栽培技术或环境条件相结合进行比较。

To control speeds for a typical alternating current motor, we usually take control variables (to change voltage and frequency of the stator power supply) from the stator side in an electric motor, which is also the only way for squirrel-cage asynchronous motor with rotor in a short-circuit state.

对于一般交流电动机的调速，我们都是从电动机的定子侧引入控制变量（改变定子供电电压、频率）来实现的，这对于转子处于短路状态的交流鼠笼型转子异步电动机是唯一途径。
