In this paper we study the optimum signal design scheme which achieves the minimum biterror probability for the multiuser data communication system in which all the subchannels are uncorrelatedHomogeneous Random Time-Varying Channels (HRTVC) and the users modulate antipodally a set ofassigned signal waveforms without carrier phase or bit interval synchronism among them. We first studythe minimum bi't error probability which can be achieved by signal design for multiuser data communicationsystem over the HRTVC. The corresponding theoretically optimum signals and their physical realizability are next considered. We find that the physical realizable optimum signals' inphase and quadrature components should be complementaryly like a group of bandlimitted white noise. If we use these signals, there is no degradation due to the presence of other users, and the time dispersion of the HRTVC is beneficial and we can fully utilize it by spreading the bandwidth of the system or the time dispersion itself. In the limiting case. the bit error probability of the multiuser data communication system over theHRTVC is equivalent to that of the single user data communication system over the additive white Gaussiannoise channel.

本文研究所有子信道都是同样统计特性的非相关齐次型随机时变信道时,数字多用户通信系统中的最佳调制波形选择即最佳信号设计问题。用户各有自己的调制波形,各波形间不需载波相位及比特区间的同步。本文研究了利用信号设计在理论上所能达到的最小比特差错概率及其对应的最佳信号设计条件、该最佳信号的物理可实现性问题以及物理可实现的最佳信号。指出物理最佳信号的同相与正交分量应互补地像一组限带白噪声。其它用户的存在不会造成系统通信质量的降低。信道的时间扩散不但无害反而有益,可以用扩展系统的带宽(提高传信率、扩大多址容量、扩展调制波形频谱)或信道的时间扩散自身(增加通信距离、减小天线尺寸)来充份利用。在极限情况下,齐次型时变信道多用户数字传输系统将等效于恒参高斯信道中的单用户数字传输系统。

By using the method of calcium phosphate precipitation,we have transfected thymidine kinase (TK) deficient mouse recipient cell line Ltk with human TK gene fragment containing recombinant bacteriophage DNA,followed by selection for TK expresion.These phage DNAs are in pairwise combinations and divided into two groups-with or without carrier DNA during the process of cotransfection.We also transfected Ltk cells with total DNA from HeLa cells,and then used the DNA isolated from primary TK transformant thus resulted as donor DNA to produce secondary TK transfor-mant In the same way,tetiary TK transformants were obtained.Number of TK molecules needed to produce one TK transformant was used as an index of transformation efficiency.The order of trans-formation efficiency is as follow: transfection with genomic DNA containing intact target gene,cotransfection with two fragments of a

用磷酸钙沉淀法,我们把带有人体TK基因片段的重组噬菌体DNA共转染小鼠Ltk~-细胞,得到TK~+转化细胞克隆。同时用HeLa细胞DNA转染Ltk~-细胞,得到第一代TK~+转化细胞,再进行第二轮、第三轮转染,得到第二代、第三代TK~+转化细胞。比较其转化效率,结果基因组DNA转化率大于基因两个片段的共转化率,更大于不加携带者DNA的共转化率。限制性内切酶消化各种TK~+转化细胞的DNA,与TK基因探针作Southern印迹杂交,结果表明两个TK基因片段共转染Ltk~-细胞时,它们可以在受体细胞里重建成一个具有完整功能的遗传单位,但在连接过程中结构可以发生改变。当用HeLa纽胞DNA转染Ltk~-细胞时,虽然连续三代转染,每一代TK~+转化细胞中人TK基因的结构未发现变化。但也不能排除基因结构改变的频率很低未能有效检出的可能性。

The characteristics of short-time anaerobic zone (with or without carriers),and its effect on phosphorus release and uptake in biological N-P removal procss were studied.The results showed that,(1)short-time anaerobic zone(HRT-2h~3h) could not improve the content of VFA in the waste water,and the cost of VFA would be sharpened if carriers were added in;(2)while the level of anaerobic phosphorus release was decreased in the zone with carriers,the ability of excess phosphorus uptake of bacteria in that zone were enhanced evidently.Thus it is inferred that the degree of anaerobic phosphorus release,fully or not,is not the sufficient and necessary condition deciding the ability of excessphosphorus uptake in the followine aerobic environment,and as to the system effect of P-removal,the motive power promoting excess phosphorus uptake has relation to the HRT and ORP o anaerobic zone.To a certain extent,a relatively longer HRT and lower ORP in anaerovic stage give out a stronger potential for excess P-removal in aerobic condition

厌氧区是生物脱氮除磷工艺系统必不可少的重要组成部分.实验室机理研究表明:短时厌氧区(HRT=2h~3h)并不能增加污水中挥发性有机脂肪酸(VFA)的数量,在厌氧区投放填料将明显增加该区VFA的消耗.相应地投放填料的厌氧区微生物有效释磷水平在同等条件下明显低于不投填料的情况.而在后续曝气条件下,前者的过度吸磷能力却明显高于后者.由此本文推断:聚磷微生物厌氧有效释磷水平的充分与否并不是决定其在后续好氧条件下过度吸磷能力的充分必要条件.在其它条件一定时,厌氧历时越长,厌氧程度越充分,微生物吸磷动力越大.
