      bitonic
    We present recursive sorting networks and periodic sorting networks based on Batcher's bitonic merger and on Batcher's odd even merger.
          
    The best previously known lower bound was the trivial Ω(lgn) bound, while the best upper bound is given by Batcher's Θ(lg2n)-depth bitonic sorting network.
          
    Of these, we selected the three most promising, Batcher's bitonic sort, a parallel radix sort, and a sample sort similar to Reif and Valiant's flashsort, and implemented them on the connection Machine model CM-2.
          
    The classical solution to this problem is given by the networks based on Batcher's Odd-Even Merge and Bitonic Merge running in log(2n ) time.
          
    The algorithm (called the (l,m) -mergesort (LMM)) is an extension of the bitonic and odd-even mergesorts.

    In a preliminary communication we reported that either the Chinese compound Prescription Yu Ping Phong Sang (a prescription used to replenish vital energy and to strengthen superficial resistance ) or its main component Astragalusexerted a bidirectional effect on PFC.In this work our effort was directed to further exploration Of the effective component of this famous prescription. It was found(1) Among the three Chinese traditional drugs of this compound prescription only Astragalus showed a definite reproducible bidirectional effect on PFC. When Ledebouriellae was administered alone or together with Atra-ctyloidis Macrocephalae only unidirectional inhibition could foe observed; (2) WhenAstragalus was extracted by water and then precipited by ethanol, the effective component seemed to be present in the supernatant, i. e. in the alcohol soluble portion. In addition some experiments have been done which give further evidences that the bidirectional effect of Astragalus is neither a false phenomenon due to "randomization" nor a false phenomenon due to a delay or a speedup of the immune reaction, but a real characteristic action of this Chinese traditional drug.

    本文报道玉屏风散中不同组分的作用,重复了我们过去观察到的黄芪对PFC的双向调节作用,又进一步观察到方中佐药——单味防风或防风和白术二味则只有抑制PFC的作用;而黄芪的免疫双调作用不是由于“机遇”,也不是推迟或提前机体免疫反应造成的假象;黄芪水提醇沉上清液——“北芪”具有与黄芪类似的效应,应是黄芪起双调作用的一个重要有效部分。

    The so-called(m,n)selection problem is the problem of selecting the msmallest(or largest)numbers from n numbers(n≥m).Parallel solution of this problem has been implemented successfully on the networks,but it is seldom studied on the multiprocessor systems.This paper,first,based on Batcher's principle of bitonic merging,proposes the bitonic selection network in which the number of comparators is O(nlog~2m)and the delay time is O(logn logm);then,we find the varing rule of the pivots in all successive ranks of the network throughobserving the data transfer property in the network.According to this rule,the parallel selection algorithm executed in time O(logn logm)on n processors is given.

    所谓(m,n)选择问题系数指从n个数中选择m个最小(或最大)者的问题.此问题的并行求解目前在网络上已得以实现,而在多处理器系统上却很少被人研究.本文首先基于Batcher的双调归併原理,提出一种比较器数目和延迟级数分别为O(nlog~2m)和O(logn·logm)~(2))的双调选择网络;然后通过观察该网络中数据移动之特点来找出双调选择网络中相继各列枢点之变化规律;最后由此规律给出了一种在n个处理器上可在O(logn·logm)时间步内完成的并行双调选择算法.
