In this paper, a full account is given of the deposition technology of the Nb films with a conventional high vacuum EF sputtering apparatus. By heating the substrate, purifying the argon, taking a long-term presputtering and using diffusion pump with liquid nitrogen trap, we can obtain the Nb films which possess adequate stability and good superconducting property which meet our needs in making Josephson devices. The critical temperature of the thick films is 9.1 K, being close to the Tc of the bulk material....

No obvious change is found in the property of our Nb films after their exposure to the atmosphere for weeks.

Acids can be separated from metallic salts in spent liquor and recovered in the form of free acids using diffusion dialysis by applying concentration difference and selective permeability of the dialyzer. By making use of solubility product principle and pH difference during hydroxide precipitate formation for heavy metal ions in spent liquor, residual dialyzate is simply and effectively treated by employing limestone powder or reducing furnace slag as neutralizing precipitant, to recover nickel and cobalt. The method herein presented goes in steps as follows. Bulk of free acids is recovered by passing spent liquor through diffusion dialyzator and reused in pickling operation. Then residual dialyzate is neutralized to pH 4-5 under normal temperature using limestone powder or reducing furnace slag. The filtrate obtained after precipitation of iron and chromium is neutralized to pH 8-9 by using NaOH or Na2CO3 to recover nickel and cobalt in the or of hydroxides or carbonates. The liquor to be discharged is a colorless, transparent solution of weak basicity.

The paper describes a method which improves the compatibility of forward voltage drop。 of 2ck,on one hand, the theory of ideal diode is used to decrease the series resistance, making the Ⅰ—Ⅴ characteristic more steep so as to improve the compatibility of forward voltage drop. On the other hand, using diffusion prineiple and the relation between forward voltage drop (V_F) and barrier potential (V_D), the time and the temperature of diffusion in the process are controllcd to further control the density...

The paper describes a method which improves the compatibility of forward voltage drop。 of 2ck,on one hand, the theory of ideal diode is used to decrease the series resistance, making the Ⅰ—Ⅴ characteristic more steep so as to improve the compatibility of forward voltage drop. On the other hand, using diffusion prineiple and the relation between forward voltage drop (V_F) and barrier potential (V_D), the time and the temperature of diffusion in the process are controllcd to further control the density and qradient of borondopping, so that the purpose to control and to improve V_F is rechieved.The results of the experiment show that all analyses in the paper are corrcct and the rate of finished products is raised greatly (by using this method in production。)

本文给出了一个改善2CK正向压降一致性的方法。一方面,利用理想二极管原理,减小串连电阻,使伏——安特性曲线更加陡直,改进了正向压降的一致性;另一方面,应用扩散理论及正向压降(V_(?))与势垒电势差(V)的关系。在工艺上,通过控制扩散时间和温度,进而控制B掺杂浓度和梯度,以达到控制并改善V的目的。实验结果证明以上分析是正确的,成品率得到大大提高。
