High-precision timing of the Quaternary standard samples with thermal ionization mass spectrometry (TIMS) U-series method

Two national stalagmite standard (GBW04412, GBW04413) and one international coral standard (RKM_4) have been determined by using thermal ionization mass spectrometry (TIMS) method. The values of ( 234 U/ 238 U) act , ( 230 Th/ 234 U) act and age are all consistent in error range with the standard values obtained by using α spectrometry.

Milestone of the meridian science──970th anniversary of the Chinese Bronze Statue of Meridian

For more than a thousand years, Chinese people were aware of the transmitted sensations by the application of needles on the body surface. This practice is called acupuncture. Acupuncture had been recorded and transcribed in writings and in drawings, until finally the acupoints were inscribed onto a bronze statue. The bronze statue was called the Meridian Figure. Deeply embodied in the bronze statue is a tripartite confrontation-prism representation of the humans body. This concept was a great scientific achievement in ancient China. The author traces the history of Meridian science described in traditional Chinese medical terms. Then he explores a clear analogy of the meridian pathway (MP) phenomenon. In a model system, by using a simple segmental in vertebrate, certain parallels can be demonstrated with the meridian concept. For example, the author demonstrated a clear correlation rule among the central mechano-sensory channels, and characteristics of positional discrimination in individual nerve cells from different receptive field inputs. The evidence suggests that the MP phenomenon is an objective neurobiological response. To clarify the research objective in this paper, the author suggests that the MP is a bi-directional pathway along which a positional message signal is transmitted. This phenomenon is evoked by physical stimulation, transmitted linearly across the human body segments, and is perceived by the brain. The MP consists of low resistance paths, is connected by the liquid media contained in the apposite membranous structure. At the cellular level, the regulation functions of MP must pass through along this low resistance path. Two aspects of the modern Meridian research are the functional regulation and the mechanism of intercellular liquid modulation at the nanometer level.

超声心动图象内外膜的自动检测与测量

为定量计算一些重要的心脏功能数据,提高心脏病的诊断水平,研究了超声心动图象内外膜的自动检测与测量技术．首先对超声心动图象进行滤波以消除图象中的噪声,并运用模糊数学理论进行模糊边缘增强,提取超声心动图象的内外膜边缘信息;接着对超声心动图象作二值化处理和椭圆曲线拟合,初步得到心脏的内外膜边缘;再采用相应的三次样条插值和平滑技术,得到光滑、连续的心脏内外膜边缘．在此基础上,再对心脏进行节段划分,并计算有关的心脏功能数据．经实验证实,用此方法可快速得到较准确的结果．     

用于智能材料与结构的NiTi丝的电阻特性研究

研究了拉伸过程中,ＮｉＴｉ形状记忆合金丝的应变与电阻的关系．结果表明,对于初始组织为马氏体的ＮｉＴｉ丝,在拉伸过程中,电阻与应变之间成线性关系．对于初始组织为奥氏体或奥氏马氏体两者混合的ＮｉＴｉ丝,当发生应力诱发马氏体相变后,曲线的斜率降低,相变前后电阻－应变保持线性关系．对于初始组织含有Ｒ相组织的ＮｉＴｉ丝,在拉伸过程中,电阻的变化规律较为复杂,取决于初始组织中各相的比例和温度．在卸载阶段,当没有相变过程发生时,电阻－应变之间呈线性关系;当有相变过程发生时,电阻－应变曲线的斜率会发生改变．
