The elemental weight ratios (Na, K, Mg, Ca, Fe, Al, Ti, Mn, Ni)/Si of Ningqiang matrix are within the range of the corresponding ratios of CV chondrite matrix, Ca/Si and Al/Si ratios are high relative to those in the other CV chondrite matrix.

宁强基质的元素重量比值（Na、K、Mg、Ca、Fe、Al、Ti、Mn、Ni）/Si处于CV球粒陨石相应比值的变化范围之内，而Ca/Si、Al/Si值相对于其它CV陨石基质的同样比值较高。

Certe, quidem do not have the brevity and the harmony of the Spanish, Italian, and Portuguese si and the French si , when the latter substitutes for oui in the most expressive sentences; si in singing, a musical note, an arpeggio of the flute, a bird's trill, noble and good for melody, for rhythm, for dreaming, for love: more for the protest and impetus, for the paroxysm, for wrath, for anathema, for dry fulminating hate, like the scratching of a ray of light, the no is far better, the rude, bitter O vast, like a roar, round and ardent like a chaos producer of life through the conflagration of all the forces of the abyss.

拉丁语中的肯定回答"Certe quidem"不如西班牙语、义大利语、葡萄牙语和法语中的肯定回答"si"那麼简洁和谐。法语中的"si"在最富有情感的情况下取代了"oui"，表示"是的"。"si"在音乐中是音符"7"，是长笛的琶音，乌的颤音，极适用於美妙的音乐、韵律、梦幻和爱情的表达。而要表达抗议、冲动、情感的突然发作、愤怒、诅咒、憎恨这一类像划火柴点火那样瞬间爆发的情感，否定回答"No"要比肯定回答适用得多。"No"中的"o"粗鲁、嘹亮、热烈，像怒吼，像给世界造成大乱的深藏在地底下的雷霆万钧之力突然爆发。

A Si-HA coating was prepared on titanium by a biomimetic method. The surface of the Si-HA coating was porous, and there was coralloid gibbosity on the surface. Si concentration was descent in Si-HA coating from outside to inside. When the Si content increased, the coating became denser and thinner.

But, because mobility of raceway groove of Si CMOS parts of an apparatus is low, bring about parts of an apparatus cross guide the Si parts of an apparatus that falls under same size, so gain of its open loop also is less than the Si operation amplifier of identical structure and dimension.

但是，由于Si CMOS器件沟道迁移率低，导致器件的跨导低于相同尺寸下的Si器件，所以其开环增益也小于相同结构和尺寸的Si运算放大器。

Simultaneity, the adsorption energies of single Si adatom on the H-terminated Si (100) surfaces are specially mapped out in this paper, from which the favorite binding sites and possible diffusion pathways have been achieved. The variety of the diffusion anisotropy with the coverage transforming is obtained. The energy barriers of the adatom diffusion are found to be higher than that on the clean surface, because the H atoms saturate the dangling bonds of the surface Si atoms.

同时，本文研究了附加硅原子在理想H-terminated Si(100)表面的沉积扩散行为，计算得到了一系列沉积点和可能的扩散路径；讨论分析了扩散行为的各向异性以及氢覆盖率对各向异性影响的规律，并且发现附加硅原子在H-terminated Si(100)表面上的扩散势垒比在清洁Si(100)表面上的高，我们认为这主要是因为氢原子饱和了表面上硅原子的悬挂键，提高了扩散势垒。

The results show that as for the as-cast castings, eutectic Si particles are characterized as fibrous or long acicular shape as well as in homogenous distribution, and the impact absorbed energy varies from 1.17 to 2.35J. After T6 heat treatment, the eutectic Si particles become small granular or short bacilliform, and the aspect ratio and area fraction of Si particles decrease evidently. The energy of the T6-treated castings is 1.45-3.80 J, which is higher than that of the as-cast castings. Furthermore, the fracture mechanisms of different regions in the castings were analyzed and discussed.

Two times hydrolyzation of Fe~(3+) and Cr~(3+) was firstly pointed out in the process of pillar preparation with hydrothermal method. In order to improve the thermal stability, Fe/Cr-Si-pillaring agent solution was synthesized by hydrolyzing Fe~(3+) and Cr~(3+) solution on the surface of silica sol, and Fe/Cr-Si-pillared montmorillonite (Fe/Cr-Si-PILM) was prepared with conventional method and hydrothermal method. Because the technical innovation of preparation is the best way to improve the PILM properties, two novel methods (Microwave method and Ultrasonication method) have been studied to synthesize Fe/Cr-PILM.In order to expand PILMs new application in the field of coal conversion, catalytic activity of Fe/Cr-Si-PILM catalyst in LongKou lignite and ShenHua coal residue liquefaction was discussed and characterized in the last part of this paper.

研究证明：蒙脱石的预处理是可行的，我们以预处理后的Ca-M为原料，研究并优化了PILM的水热法制备工艺，提出了金属离子的二次水解法；为了提高PILM的热稳定性，我们自制了硅溶胶，合成了Fe／Cr-Si三元复合柱化剂，并制备了Fe／Cr-Si-PILM；在PILM合成中，制备技术的革新是改进PILM性能的重要方法，为此我们探索了微波合成法和超声波合成法在制备Fe／Cr-PILM中的应用；最后，我们选择龙口褐煤和神华煤液化残渣为研究对象，探索了Fe／Cr-Si-PILM催化剂在煤炭液化中的应用，希望能开拓PILM应用的新领域。

However, because of the lattice mismatched and imperfect band structure, the application of Si〓Ge〓/Si heterojunction has been constrained. The incorporation of carbon into Si〓Ge〓 layer, provides an additional degree of freedom in Si-based band and strain engineering.

然而，通常外延生长的Si〓Ge〓/Si结构是一种晶格失配异质结，受到临界厚度的限制，而且也不具备理想的能带结构，限制了其进一步的应用。C掺入Si〓Ge〓合金，为Si基能带工程和应变剪裁提供了新的自由度。
