The optically based technique of electro-optic (EO) sampling has been used for diagnosing the internal high-speed signals of integrated *** of the features that make the EO sampling technique very promising is a minimal probe: the EO sampling technique does not require an electrode and ground plane incorporated as part of a probe so that, compared with conventional metal probes, the invasiveness of an EO probe is minimal.

*** The topic of my speech today is"Contribution of the Neo-Confucianism to the Modern International Law:for its conception in Europe and for its acceptance in Japan."This is quite a challenging topic,since it is generally believed that the modern international law is exclusively a product of the European civilization based on the European philosophy;and that non-European nations including China and Japan accepted it as a wholly foreign legal system.

The lifeworld is, according to Husserl, the horizon of all our experiences, in the sense that it is the background environment of human being＇s competences, practices, and attitudes. The lifewofld is the intersubjective, pre-given in the ontie sense, and immediately perceived world of everyday life. Although Husserl has distinguished the lifeworld from the objective world that natural science describes with mathematical methods, we cannot divide the world on the practical level into the perceived world of ordinary life and the scientific world. The characteristic of human beings is that they live in the environment which they have enormously changed. Modem science has accelerated this tendency： the contemporary world is constructed so deeply scientifically and technologically. Accordingly, as Ulrich Beck pointed out, the risk of the technologically constructed world is often invisible/unperceivable. The disaster at Fukushima nuclear power plants is a terrible testament of this kind of risk. In order for a land to become the lifeworld of meaningful human interactions, the land should be first of all safe and livable for all of us. The risk calculation made by Tokyo Electric Power Company was shown to be sloppy and deceptive. The contemporary techno-science should be democratically governed and watched by all kinds of stakeholders, and never be left it to the specialists of science. For re-establishing the livable and sustainable lifeworld, safety, resilience, and vulnerability should be the fundamental values. And, the autonomy of the local residents, including the most vulnerable people, through the democratization of the techno-science must be the fundamental value to establish and protect such a safe environment.

本文提出一种称为旅行时线性内插(LTI,下同)的新的射线追踪方法。与常规的方法相比,用该方法计算二维速度结构模型的旅行时和射线路径速度快、精度高。 LTI方法的公式推导基于二维网格模型,旅行时和射线路径的计算仅在网格的边界上进行。因此,在速度不变的网格单元内其射线路径总认为是直线。该方法适用于层析成像研究。 LTI算法分为两步:首先计算所有网格单元边界上的旅行时;然后追踪所有炮检对之间的射线路径。位于网格单元边界上任意一点的旅行时可根据其相邻网格节点上已经计算得到的旅行时线性内插获得,对于有数个可能解的情况,以费马原理为准则,选择正确的旅行时和射线路径。本文将LTI方法与打靶法以及程函方程的有限差分法(FDM,下同)进行了数值计算比较。结果表明,LTI方法在旅行时及射线路径计算方面速度快、精度高。由于程函方程的常规FOM公式可由LTI法独立推导得出,故可认为LTI方法是常规FDM的更新版本。在推导过程中,理论上可以证明LTI方法比FDM精度高。而且,在LTI方法中,可以避免当速度变化剧烈时使用Vidale方法出现的数值解不稳定性。

The time evolution of the equation of state w for quintessence scenario with a scalar field as dark energy is studied up to the third derivative (d3w/da3) with respect to the scale factor a, in order to predict the future observations and specify the scalar potential parameters with the observables. The third derivative of w for general potential V is derived and applied to several types of potentials. They are the inverse power-law (V = M4 + α/Qα), the exponential , the mixed , the cosine and the Gaussian types , which are prototypical potentials for the freezing and thawing models. If the parameter number for a potential form is n, it is necessary to find at least for n + 2 independent observations to identify the potential for0m and the evolution of the scalar field (Q and ). Such observations would be the values of ΩQ, w, dw/da, ???, and dwn/dan. From these specific potentials, we can predict the n + 1 and higher derivative of w;dwn + 1/dan + 1, ???. Since four of the above mentioned potentials have two parameters, it is necessary to calculate the third derivative of w for them to estimate the predict values. If they are tested observationally, it will be under- stood whether the dark energy could be described by the scalar field with this potential. At least it will satisfy the necessary conditions. Numerical analysis for d3w/da3 is made under some specified parameters in the investigated potentials, except the mixed one. It becomes possible to distinguish the potentials by the accurate observing dw/da and d2w/da2 in some parameters.

基于JIS R 5201《水泥物理测试方法》中的标准砂浆模具(40mm×40mm×160mm),研究了一种评价抗硫酸盐侵蚀的测试方法。通过在该标准模具两端放置不锈钢隔板,依次制备出10、15、20、25和40mm厚的砂浆,分别测定不同浸泡时间下砂浆试样的膨胀长度。结果表明:垂直于长轴的横截面积越小,即样品越薄,样品出现膨胀的时间越早且膨胀率越大。横截面的等效圆半径与材料膨胀率为0.05%时的龄期的立方根成正比。ASTM C 1012标准中砂浆的制备方法(配合比和龄期)与本方法类似,但本方法成型更简单易行,实用性更强。采用该方法所制备的10和15mm厚的样品与ASTM C 1012—2010标准中规定的测试时间相符。
