To understand the principle and limitation of chalcogenide alloy Ge2Sb2Te5 （GST） in solid-state memory devices during crystallization, it was necessary to develop a physically realistic model that could reflect the electrical and thermal properties of these media. A novel comprehensive numerical model has been developed for simulating these memory devices, which describes the electrical and thermal behavior using the solution of the nonlinear, time-dependent electrical and heat conduction equation. The finite-difference-time-domain technique was adopted to compute the electrical field and heat distribution in the device. Several contributing factors that affect the crystallization switching process such as the geometry of the GST layer, temperature and electric field dependency of the electrical conductivity have been discussed. The results of the simulations were then used to provide critical guidelines for fabrication and optimization of the device performance.

目的本研究的目的是评估超低剂量胸部cT扫描(ULd-cT)诊断影像的质量,其剂量类似于胸部X线成像辐射剂量,采用滤波反投影重建(FBP)、适应性统计迭代重建技术(ASIR)和基于模型的迭代重建技术(MBIR),并将其与标准剂量诊断cT(Sdd-cT)或单独采用FBP进行重建的低剂量诊断cT(Ldd-cT)进行比较。方法将进行ULd-cT采集的42例病人的胸部cT平扫影像与同一次检查的Sdd-cT或Ldd-cT影像进行比较。采用5级法对所有cT数据集上的明显胸部病灶进行噪声测量和影像质量的评估。结果 ULd-cT、Sdd-cT和Ldd-cT的辐射剂量分别为(0.16±0.006)mSv、(11.2±2.7)mSv、(2.7±0.9)mSv,ULd-cT与Sdd-cT的差异具有统计学意义(Pd-cT的影像质量显著提高(Pd-cT采用MBIR重建能够与Sdd-cT或Ldd-cT时发现的非钙化性肺结节一样多。然而,ULd-cT的影像质量在显示毛玻璃样病灶或肺气肿时明显减低。结论采用基于模型的迭代重建ULd-cT,当其辐射剂量相当于后前位(PA)及侧位胸片时,可以检出肺结节。要点①随着胸部cT应用增加,辐射剂量是一个关键问题。②超低剂量胸部cT的辐射剂量相当于常规胸部摄片。③超低剂量胸部cT影像质量可以达到诊断要求。④超低剂量胸部cT能够清晰显示肺实性结节。

The lithosphere and the atmosphere/ionosphere, continuously exchange energy through various coupling mechanisms. Earthquake creates waves of energy, e.g. direct shock acoustic waves （SAWs） and Rayleigh wave induc.d.acoustic waves （PAWs）. In the event of an earthquake occurring beneath the sea, atmospheric gravity waves {AGWs） are also generated. If the earthquake is large enough （Mw 〉 6）, SAWs, PAWs and AGWs induce detectable ionospheric plasma perturbations. Inferring the seismological information from these seismo-ionospheric manifestations is the subject that pertains to ionospheric seis- mology. Both ground and satellite based advanc.d.radio techniques are being used in monitoring ionospheric plasma perturbations. In this study, seismo-ionospheric anomalies and implications from recent GNSS observations in India and South-East Asia are dis- cussed, mainly pertaining to the following. （1） From the ionospheric plasma response to 2015 Nepal earthquake, the estimated group velocity for Andaman and Indian shield re- gions are 2100 ms i and 3900 ms-1 respectively and validated from ground measurements. （2） Atmospheric acoustic resonance at 4.0 mHz and a train of wave packet of TEc variation resulting from the beat phenomenon observed at the site ＇umlh＇ and （3） GNSS-based tsunami warning which is going to be promising tool in augmenting the existing tsunami warning systems.

A 3m drop-tube was used to investigate the solidification of Fe50cu50 hypoperitectic alloy. The falling droplets solidified as spheres and splats. The obtained particles range from 1000μm to 80μm in diameter. It was found that the phase separation occurred if the Fe-cu liquid was undercooled to a certain extent before *** the big particles macroscopic separation of Fe-rich phase always appeared in the cented of the particles, and in the small ones the Fe-rich phase usually solidified as little spheres. In the flakes the Fe-rich and cu-rich layers alternatively displayed from top to bottom.

The three most common instruments for high-sensitivity magnetization measurements (the vibrating-sampie magnetometer, the alternating gradient magnetometer, and the SQUId magnetometer) are described and their limiting sensitivities are discussed. The advantages and disadvantages of each are described. Magnetometers using micro-machined force detectors are briefly mentioned.

considerable progress has been achieved in friction stir welding （FSW） of steels in every aspect of tool fab- rication, microstructure control and properties evaluation in the past two dec.d.s. With the development of reliable welding tools and precise control systems, FSW of steels has reached a new level of technical maturity. High-quality, long welds can be produc.d.in many engineering steels. compared to traditional fusion welding, FSW exhibits unique advantages producing joints with better properties. As a result of active control of the welding temperature and/or cooling rate, FSW has the capability of fabricating steel joints with excellent toughness and strength. For example, unfavorable phase transformations that usu- ally occur during traditional welding can be avoided and favorable phase fractions in advanc.d.steels can be maintained in the weld zone thus avoiding the typical property degradations associated with fusion welding. If phase transformations do occur during FSW of thick steels, optimization of microstructure and properties can be attained by controlling the heat input and post-weld cooling rate.
