A new covalent structural scheme for water polymers is proposed. The observed properties of "polywater" are related to the structures of the suggested homologous series of molecules. Mechanisms of formation are suggested. 相似文献

DFT is widely applied in the field of signal process and others. Most present rapid ways of calculation are either based on paralleled computers connected by such particular systems like butterfly network, hypercube etc; or based on the assumption of instant transportation, non-conflict communication, complete connection of paralleled processors and unlimited usable processors. However, the delay of communication in the system of information transmission cannot be ignored. This paper works on the following aspects： instant transmission, dispatching missions, and the path of information through the communication link in the computer cluster systems; layout of the dynamic FFT algorithm under the different structures of computer clusters. 相似文献

In the report of the Committee on Genetic Effects of Atomic Radiation, which appeared in the 29 June issue, the number "200 million children" in line 18 of the third column on page 1163 is an error. The question should read: "What is the estimate of the total number of mutants which would be induced by this radiation dose and passed on to the next total generation of about 100 million children?" 相似文献
