| 1 | Parameters in wind-wave frequency spectra and their bearings on spectrum forms and growth显示文摘The spectrum variance m0, peak frequency ω0 and peakness factor p are expressed in terms of nondimensional fetch and duration by making use of relations which are derived through comparing and analyzing existing empirical formulas for the growth of significant wave height and period. The main features of spectrum growth as specified by these parameters agree with those of the JONS-WAP experiments. For given wind speed and fetch, the high frequency parts beyond the peaks of shallow water spectra almost coincide with that of the corresponding deep water spectrum, whereas the low frequency parts differ appreciably. The method developed in this paper predicts smaller significant wave height as well as smaller wave period for shallow water spectra in contrast to the theoretical result of Kitaigorodskii ef al, in which the peak frequency, and consequently the significant wave period, remains basically unchanged for different water depths. Spectra are further reduced to a form in which only significant wave | Wen Shengchang (S. C.

| 2 | Numerical Simulation of Microphysics in Meso-β-Scale Convective Cloud System Associated with a Mesoscale Convective Complex显示文摘Numerical simulation of meso-β-scale convective cloud systems associated with a PRE-STORM MCC case has been carried out using a 2-D version of the CSU Regional Atmospheric Modeling System (RAMS) nonhydrostatic model with parameterized microphysics. It is found that the predicted meso-r-scale convective phenomena arc basically unsteady under the situation of strong shear at low-levels, while the meso-β-scale convective system is maintained up to 3 hours or more. The meso -β- scale cloud system exhibits characteristics of a multi-celled convective storm in which the meso-r-scale convective cells have lifetime of about 30 min. Pressure perturbation depicts a meso-low after a half hour in the low levels. As the cloud system evolves, the meso-low intensifies and extends to the upshear side and covers the entire domain in the mid-lower levels with the peak values of 5-8 hPa. Temperature perturbation depicts a warm region in the middle levels through the entire simulation period.

| 3 | The sea/land breeze in the northern coastal area of Shandong Peninsula显示文摘In this paper the seasonal variation and structural characteristics of the sea/ land breeze in the northern coastal area of' Shandong Peninsula are studied in two ways: one is the analysis of the observed wind data, and the other is numerical simulation and experiments. Firstly, the hour to hour wind data through the year 1984 at Longkou Meteorological Station and Yantai Oceanographic Station are analysed through energy spectra and hodograph. It is revealed from the analysed results that the effects of the sea/ land breeze in the area are notable in spring, summer and fall, especially in May. However, in winter the effects of sea / land breeze are not obvious. because the cold noitherly is prevailing. Secondly, a two-dimensional non- linear model of primitive equations is used to study the sea / land breeze circulation in May in the area. The results of numerical simulation consist basically with the analysed results of the observed sea / land breeze.

| 4 | COMPUTERIZED PLOTTING OF LOW SKIN IMPEDANCE POINTS显示文摘The distribution of low skin impedance points(LSIP)was studied on 68 subjects with a computersystem designed for the measurement of skin impedance.The results demonstrated that LSIPswere basically distributed along the 14 channels,the overwhelming majority located right on orwithin 5 mm bilaterally to their courses.LSIPs were found in the area between every two chan-nels only in a few cases.Moreover,there was no marked natural fluctuation of skin impedance inthe human body and the distribution of LSIPs was considerably stable,which could be plotted onany day in the experiment.It is clear that such particular distribution of LSIPs along channelswas really a biological phenomenon,not an experimental error.However,the distribution of lowskin impedance was not an uninterrupted solid line but a series of LSIPs basically along thechannel course.The method used in this work was accurate,reliable and repeatable which hasupgraded the measurement of LSIPs to a new level.Under certain conditions,skin impedancecan be used as an objective index in channel research. | 胡翔龙 吴宝华 黄晓卿 许金森 | 1992 | Journal of Traditional Chinese Medicine1992，12，4： | 1 |

| 9 | AR 5395: A MOTION OF THE DARK MATTER IN 2N FLARE ON 9 MARCH显示文摘On March 9,1989,a 2N flare erupted in AR5395 active regin (N32.E51) in the solar disc between 0220 UT and 0300 Unaccompanied by an M 1.8 X event, and after the maximun the dark matter moved and ejected evidently. From the analyses it is believed that the motion of the dark matter is caused by the flow of chromospheric matter along the direction of the weakening of the magnetic field under the action of the magnetic tension after the flare, the ejection results from the action of the lower magnetic field during the downward flow of the dark matter, and the sunspot penumbre may be the supplementary source of the flow and ejected matter. | Li Zhi, Luan Di, Li ZhikaiYunnan Observatory, Chinese Academy of Sciences | 1990 | 天文研究与技术1990，，4： | 0 |

| 16 | Preliminary research on sea-level changes of the South China coast since late Epipleistocene显示文摘Several views on sea-level changes of the South China coast are briefly introduced in this paper. On the basis of 236 samples whose ages are determined by 14C chronological method and their sites are corrected with ancient water depth and crustal deformation, a basic model about sea-level changes of the South China coast since late Epipleistocene is set up. This model basically accords with the general cognitions of predecessors, i. e. it not only represents the common characteristics of sea-level changes of the East China coast but has some features of the South China coast itself. In general, this model is relatively close to the Fairbridge’s curve, indicating that the sea-level undulations exist since 6 ka ago but the ranges of undulations are slightly larger than those of Fairbridge’s curve. | Zhang Hunan Zhao Hongmei Seismological Bureau of Guangdong Province, Guangzhou 510070, China | 1991 | Acta Oceanologica Sinica1991，10，4： | 0 |

| 18 | A study on sound production acoustics in the black cicada(C.atrata Fabricius)显示文摘The long rib of the sounding membrane in the black cicada is ananalog to the beam clamped at one end.The fundamental frequency ofactivation sound is between 3900—5500 Hz and is basically consistent with thepossible range of the main peak frequency (MPF) of song in the blackcicada.The operculum (Op),tymbal cover (TC) and joint membrane (JM) arerespectively analogous to a unifor square plate clamped at one edge and free atthe others,to another plate at two opposite sides and free at the other,and to arectangular membrane clamped at four sides.The fundamental frequencies ofactivated vibrationare basically consistent with theMPFs and main high frequency components of vibrations of the Op,TC andJM,respectively.The resonant cavity and spiracles on both sides are analogous to a currentresonace circuit and to a resistance connected in parallel at the output ends,andthe resonant frequency and quality factor of the circuit are in good agreementwith the MPF and its tuning sharpness of song in the black cicada. | JIANG Jinchang, XU Muling, CHEN Hao and ZHANG Hong(Institute of Biophysics, Academia Sinica) | 1990 | Chinese Journal of Acoustics1990，9，2： | 0 |
| 19 | THE CHARACTERISTICS OF THE STANDARD CELLS WITH LOW TEMPERATURE COEFFICIENT显示文摘Through a series of precise measurements of the EMF of acid H-type cells (there is Pb, Sn, or Pb-Sn in the amalgam) provided by three factories, the characteristics of these cells were studied. The measuring apparatus and temperature control system are basically similar to those used in the experiment of 1974. The temperature graclient of oil bath was measured by a precision platinum resistance thermometer. It was found that the horizontal temperature gradient of the bath was less than 0.001℃ under any temperature and the gradient between any two points in the working region was less than 0.002℃. | 胡衍瑞 | 1982 | Chinese Science Bulletin1982，27，2： | 0 |
