The composition, crystal modification and microstructure of Na〓SO〓/SiO〓 CESM are researched by using metallography microscope, X-ray diffractometry, scanning electron microscope and energy dispersive spectroscopy. The results show no new substance appears other than quartz and thenardite, but the crystal modification phenomenon is discovered; quartz and thenardite are combined very well with wetting and mechanical inserting; a dense and continuous microstructure is seen in fractography, but holes and cracks defects are found too.

研究结果表明最终制备出的复合相变储能材料在常温下的主要物相为α—石英和芒硝〓—T，与制备前相同；制备工艺对复合材料的最终的物相变化影响不大，仅仅是制备过程中出现各组份的晶型转变；复合储能材料物相分布较为均匀，预制体粘结良好，两相基本互相包覆，其间仅是因浸润结合而形成的机械嵌合作用；复合储能材料中存在有封闭孔、杂质、未渗区等各种缺陷。

The optimum reaction condition for preparation of CoPcY is as follows: a , using CoCl2 as the exchanged salt ; b , complexation temperature of 180 ; c . complexation catalyst of NH4C1 and A1C13 .2, The unsymmetrically substituted cobalt phthalocyanine complexes were synthesized by statistical condensation of phthalic anhydride and tetrabromophthalic anhydride, and further immobilized in MCM-41 molecular sieves by zeolite synthesis method, as well as characterized by XRD,FT-IR,DRS, 1HNMRetc. The catalytic property of CoPcBrx/MCM-41was tested by cyclohexane oxidation using H2O2 or t-BOOH as oxidant.

2采用本路线制备CoPcY的最佳条件为：a、采用氯化钴作为待交换的金属盐；b、络合温度以180℃为宜；c、起始反应物为苯酐、尿素、氯化铵、氯化铝、CoY时，制备出的CoPcY的催化性能最好； 2、首次采用苯酐和四溴苯酐均相浓缩统计合成法制得了不对称取代的金属钴酞菁络合物，并采用~1HNMR、FTIR、DRS等对其进行了结构表征；此外，采用沸石合成法将其固定于MCM-41中孔分子筛，并对其催化性能进行了考察。

From the cardboard to the corrugated paper, even the tools used were off the peg to echo Master Cheng Yen's call to be less wasteful.

找到硬度适合的纸版后，还得描绘出纱筒的上下盖子，最麻烦的是要将盖子和投币孔一个个剪下来。

By rotating the X-axis of the measurement coordinates, the straightness data of each generatrix are transformed into a unified 3D coordinate system whose Z-axis superposes the least square mean axis calculated with the data of the multiple generatrices. The computer simulations and experiments prove that the construction by rotating the abscissas can effectively eliminate the distortion of the constructed profile.

通过测量坐标系中X轴的旋转，将各条母线直线度偏差数据统一到同一个空间坐标系中，采用两端面圆的最小二乘轴心的连线作为零件轴线，消除了直接构造所带来的表面变形，并能进一步计算出被测内孔的直径、圆度和轴线直线度误差，使测量系统集成化和多功能化。

This paper has described the basic function and qualification of the compensating brake master cylinder admeasuring apparatus firstly, given an introduction of gross structure, measuring principle and method, put its emphasis on the dissertation of working principle of main composing parts, such as endoscopic-micro optical system, CCD pick up camera and precision machinery system, and on the design of optical imaging system. It has analyzed the main error and the influence on measuring accuracy as well as giving a conclusion of error analysis.

本文首先叙述了制动主缸补偿孔测量仪的基本功能和技术指标，接着介绍了仪器的总体结构、检测原理与方法，重点对系统的主要组成部分，如内窥显微光学成像系统、CCD摄像机和精密机械系统等的工作原理进行了论述，并对光学成像系统进行了设计，最后分析了系统的主要误差来源及其对系统检测精度的影响，并给出误差分析结论。

The scale, tremolo speed and temperament of the Oriental models therefore favor single note melodies while those of German tremolos favor chording.

使用单簧的十孔吹出的旋律声音干净而又清晰，也可以吹和弦，当然喽还有压音。

The pull-out strength of these deices is at least equal to that of a suture passed through drill holes in bone, and they are especially useful in deep wounds with limited room, such as in the shoulder.

这种装置的拉出强度至少相当于缝线穿过骨孔固定的强度。这种方法在术野小且伤口深的情况下非常有用，例如在肩关节手术中。

That if the process can produce much liquid phase during the sintering, and which can become into completely-crystal needle-shap or aborization or bar-shap calcium ferrite instead of glass in the cooling process; if the magnetite is interweaved by the caking into the melting corrosion structure, the granular structure or the eutectic structure instead of exiling in the massive isolation; if the mount of the poreis is little, and uniformitly distributing; if the grain is little; if the organizational structure is symmetrical, all of which can improve the quality of the sintering.

另外还归纳出有利于强度提高的工艺参数和操作制度。分析工业试验和水钢现行生产的矿物组成、结构表明，水钢烧结矿以他形晶磁铁矿为主，铁酸钙为主要的粘结相，多形成熔蚀结构、粒状结构和共晶结构，强度较高；而在台车边缘和表层，由于存在较严重边缘效应和点火温度较低，使该区域的烧结矿组织结构疏松，局部呈蜂窝状或薄壁大孔状，铁酸钙较少而硅酸二钙和玻璃质较多，形成骸晶状结构和磁铁矿连晶，强度较低，致使返矿升高。

With the porous hulls of other grains, steam easily passes through, so no significant pressure is produced.
