In the first year, a dynamic energy interpolating circuit will be developed to substitute for the static transfer switch of off-line UPS's. This circuit is able to provide the output power for off-line UPS's about half-cycle time while the utility is blackout but the inverter still no yet starts to take over the UPS output.

The absorption band at 2240 A discovered by Stucklen in an underwater spark does not agree with the band observed by Hulthen and Zumstein in a high temperature oven and later studied by Grundstrom. The important difference lies in the complete lacking of the R-branch lines in Stucklen's band. New experimental investigation led to the discovery of the unfound R-branch lines. This is a strong evidence that the bands are actually the same.
Stcklen氏发现用铜极在水中生火花有一吸收光带位於2240A区域此光带与Hulthen氏及Zumstein氏及Grund-strom氏在高温度炉中用铜之蒸气加以氢气所得之吸收光带(亦在2240A附近)不能一致最大之分别在Stucklen之光带全无R支谱线新实验工作发现R支谱线之存在得R(0)至R(13)之十四根线确实证明Stucklen之光带并非另一新带。

The results showed that: at metaphase I, the homoeologous chromosome pairing among different F1 hybrids ranged from 2.0 to 11.4 bi-valents formed by homoeologous chromosomes per pollen mother cell, and very few multivalents, and even very few bivalents were formed by two chromosomes within one genome rather than homoeologous chromosomes in some PMCs; at anaphase I, all biva-lents were disjoined and most univalents were divided.
结果表明在中期I阶段,这些杂种一代的近缘染色体联会变化很大,每个花粉母细胞中二价体形成的数目从平均2个到11.4个不等,甚至在某些花粉母细胞中,还发现极少的多价体和非部分同源染色体所形成的单基因组内二价体;在后期I时,所有的二价体分离,同时多数单价体也分离,分离的二价体和分离的单价体都移向两极,从而形成两组染色体;因为这时完整花粉母细胞中分离的二价体在两组染色体中总是对应出现,从而根据半二价体上染色体重组的位置可以分析在二价体的四分体时期发生在非姊妹染色体之间的多种染色体交换类型,如单交换、三线双交换、四线双交换、四线三交换和四线多交换。

The equations for two-conductor coupled-line Marchand baluns are derived. The analysis and systematic design procedure for multi-conductor coupled-line Marchand baluns are also presented, and verified with a few fabricated multi-conductor coupled-line Marchand baluns. Two MMIC broadband diode frequency doublers using multi-conductor coupled-line Marchand baluns are implemented to demonstrate the design procedure of multi-conductor coupled-line Marchand baluns. The MMICs achieve miniature chip areas with broadband performances in millimeter-wave regime.

We performed a simulative test, which confirms that wavelet analysis can separate annual wobble and Chandler wobble. Our results show that this method can be used in astronomical geodynamies effectively. This paper is divided into two parts. The first is about statistic characteristic of polar motion. Polar motion includes secular motion, long period fluctuations, Chandler wobble, annual wobble and high frequency wobble. The secular motion is 3.4mas/year and towards 760W meridian. Long period fluctuations have difference periods in x-axis and y-axis. They are 31.7-year and 24-year in x-axis and 28.5-year and 22.9-year in y-axis. These 2~? decades fluctuations have an amplitude of about 30 mas , and are very nearly linearly polarized, with the observed motion of pole being almost entirely along a line between 360E and 1440W. There is a 55.4-year wobble whose amplitude is 9 mas. The amplitude of the interannual fluctuations is about 4? mas. The amplitude of long period fluctuations decreased after 1970. The annual wobble is a steady wobble. It retrograde wobble is only 1/20 of prograde wobble in amplitude.
本文的工作主要分为两部分:第一部分是通过分析POLE97序列,我们对极移的统计特性有了一个较全面的认识,极移主要包括趋势项、长周期项、Chandler项、周年项和高频项:趋势项的方向是西经76°,速度为每年3.4mas;长周期项中Markowitz 项在X、Y两个方向有不同的周期,它们分别是:X方向的两个周期是31.7年和24 年,Y方向的两个周期为28.5年和22.9年它们叠加在一起是一个线偏振运动,最大振幅约为30mas,偏振方向在西经144°和东经36°之间;极移的长周期波动中还存在一个 55.4年周期的圆周运动,振幅约为9mas;十年尺度变化的振幅在4~6mas之间,在Y 方向十年尺度的成份比较多,它们的周期在X方向和Y方向不是对应的;从七十年代年开始长周期变化的振幅明显降低;周年项是一个振幅稳定的摆动,在X、Y两个方向的振幅略有差别,逆向运动振幅大约为顺向运动振幅的1/20;Chandler摆动的振幅自1900年以来经历了几次较大的变化,其中包括1915年和1955年两次极大值,振幅分别达到0&。25和0&。28,以及1925~1940期间小于0.09的过程,Chandler项在X、Y 两个方向的振幅几乎完全相等,其逆向运动振幅不到顺向运动振幅的1/50。
