To provide constraints on the rheological properties of garnet, we have experimentally investigated the creep behavior of garnet at high pressures and temperatures using a deformation-DIA. Samples were cold-pressed from a garnet powder and deformed at constant displacement rates ranging from 1.1×10^-5 to 2.6×10^- s^-1 at high temperatures （1 273-1 473 K） and high pressures （2.4-4.1 GPa）. Differential stress and pressure were measured using X-ray diffraction techniques based on the elastic strain of various lattice planes as a function of orientation with respect to the applied stress field. The plastic strain of a deforming sample was monitored in-situ through a series of radiographs. Our results provide a measure of the dependence of creep rate of garnet on the temperature with an activation energy of -280 kJ/mol and on pressure with an activation volume of -10×10^-6 m3/mol. The flow behavior of garnet quantified by this study provides the basis for modeling geodynamic processes occurring within subducted lithosphere.

根据纤维素、半纤维素、木质素在高温高压水中分解速度相差很大的特点 ,提出了一条稻壳资源化的新工艺 ,以便减少废弃物、最大限度地得到糖类化合物。新工艺主要包括连续水蒸汽蒸煮爆碎处理、连续近临界水处理和燃烧三步。研究了连续近临界水处理过程中温度和停留时间对液相分解产物的收率和残渣组成的影响 ,并得到了较优的操作条件。通过对新工艺中固形物组成变化的研究得知 :水蒸汽蒸煮爆碎处理过程主要分解半纤维素 ,而连续近临界水处理同时水解纤维素和含硅化合物。新工艺可将约 80 %的碳源转化为水溶性物质 ,其中多聚糖和单糖的收率可达 40 % (wt)以上。新工艺为稻壳的全面综合利用提供了一条新途径。

The space-time distortion perceived subjectively during saccadic eye movements is an associative phenomenon of a transient shift of observer’s visual frame of reference from one position to another. Here we report that the lines of subjective simultaneity defined as two spatially separated flashes perceived during saccades were nearly uniformly tilted along the physical time-course. The causality of the resulting space-time compression may be explained by the minkowski space-time diagram in physics.

＜正＞ A demultiplexer （DmUX） is one of key subsystems of practical Rapid Single Flux Quantum （RSFQ） circuits and systems. High speed data from RSFQ circuits should be converted into sufficiently low speed ones for transmission to and processing by room temperature electronics. We designed, fabricated and successfully tested an RSFQ DmUX for applications such as analog-to-digital converters. The DmUX was designed on the svnchronous shift-and-dump architecture, which comprised a clock control circuit and a sift

＜正＞Thyroid anaplastic carcinoma is a highly malignant tumor and a rapid increase in size, extension beyond the thyroid, widespread metastasis are characteristics of this aggressive carcinoma. The details of the poor prognosis in this carcinoma, however, are not clear. Recently one of the causes has been proposed to be closely related to granylocyte-colony stimulating factor （G-CSF） produced by the tumor cells. We encountered two cases of anaplastic carcinoma in the thyroid that exhibited rapid growth, giant

＜正＞ Owing to the potential use of bulk InxGa1-xAs crystal as the substrate material for InGaAs-based optoelectronic devices, growth of bulk InxGa1-x,As crystals has attracted a great amount of attention in the recent past. Realizing the practical difficulties in growing compositionally homogeneous bulk InxGa1-xAs single crystals of large size on ground, Kinoshita et al. [1] have proposed a novel growth technique, named traveling liquidus zone （TLZ） method, which is expected to give better growth results under micro-gravity conditions. In this technique, a narrow melt zone is created by using a gradient temperature profile, which saturates solute at equilibrium. This zone travels along
