Monetary easing--even unorthodox--is like pushing on a string when （1） the problems of the economy are of insolvency/credit rather than just illiquidity;（2） there is a global glut of capacity （housing, autos and consumer durables and massive excess capacity, because of years of overinvestment by China, Asia and other emerging markets）, while strapped firms and households don't react to lower interest rates, as it takes years to work out this glut;（3） deflation keeps real policy rates high and rising while nominal policy rates are close to zero; and （4） high yield spreads are still 2,000 basis points relative to safe Treasuries in spite of zero policy rates.

According to the demand of high magnetic field power supply, reference is increased with a set ramp rate and stops at a set stable value, so reference system is composed of digital setting and digit to analog converting circuit. But the stability of reference is mostly guaranteed by the performance of D/A circuit, so D/A circuit is particularly studied in reference system. The scheme of D/A circuit, the selection of DAC and its voltage reference, hardware anti-jamming design and PCB design are discussed in detail, and software of remote control and PLC are discussed in brief. Zero-flux DC current transformer well satisfies the demands of the high stability of Load current detection unit, so the principle of zero-flux DC current transformer is analyzed; in the mean time a project which detects the long term stability is designed. During 8 hours, analog signal which is detected with high precision digit multimeter is recorded in computer at 1HZ frequency by GPIB communication. The drift error source and related parameters are explained in the compare-amplify part. Detailed subtraction circuit is designed; also amplifier chip and periphery components are selected and verified according to the theory of error analysis.
