目的：采用碳纤维增强碳复合材料(carbon fiber reinforced carbon，C/C)与羟基磷灰石(hydroxyapatite，HA)复合形成新型种植体，研究它们与骨结合界面的性质，为开发新型种植体提供实验依据。

The ablative performance of C/C composites with different carbon matrix was investigated by stagnation point ablation test.

炭基体在C/C复合材料的组成中占有很大的比重，因此炭基体不同的结构状态往往对C/C复合材料的各项性能有显著的影响。

Higher substrate temperature can lead to decrease of bond angle disorder of C bonds; It can also promote the outdiffusion of the implanted C atoms and the formation of C-C bondings.

较高的基片温度可以导致C键键角无序化程度的降低；也可以促进注入的C原子向表面的扩散及C-C键的形成。

The results show that TaC with form of coating enwrap evenly and compactly around with the carbon fiber in C/C-TaC composites and form the cannular microstructure, both the average strength and toughness of C/C-TaC composites sample increase apparently.

结果表明：C/C-TaC复合材料中TaC以涂层形式均匀致密地包覆在炭纤维周围，形成管状微观结构，大大提高C/C-TaC复合材料试样的平均强度和韧性。

Visual inspection of spectra shows that the differences observed in spectra of different cells in band intensities at 1603cm^(-1)(C=C in-plane bending mode of phenylalanine and tyrosine) and 1616cm^(-1)(C=C stretching mode of tyrosine and tryptophan) are obvious. This can be used as the marks for blood cell of defferent species. And LTRS is a useful tool for the blood cell analysis.

结果显示不同物种血红细胞的拉曼光谱在1603cm^(-1)苯丙氨酸和色氨酸的C=C平行振动模及1616cm^(-1)酪氨酸和色氨酸的C=C拉伸模有明显的差异，这可以用来作为不同种血红细胞鉴定的特征标记，表明激光镊子拉曼光谱技术可以成为血红细胞分析的有效手段。

Then, when you type C-c C-e, it takes the code within the region, passes it through the actual C preprocessor, and places the output in a window called *Macroexpansion*.

然后，当你输入C-c C-e，它把选取区域中代码传给一个实际的C预处理器，并把输出结果放到一个叫*Macroexpansion*的窗口里。

With the characterization of NMR and IR, combining with the synthesis of active species and studies of their structures, it is suggested that the hydride [RuHCl(PPh3)3], being favorably formed in the acid media, exhibited higher activity in the reduction of the C=C bond, while the hydride [RuH4(PPh3)3], being preponderantly formed in the basic media, showed activity and higher selectivity towards the C=O reduction.

通过核磁、红外等表征手段，并结合可能催化活性配合物的合成和结构研究，推测了在非水介质中对C=C和C=O双键起到活化作用的催化剂活性物种和可能的选择加氢反应机理，即，催化剂[RuCl2(PPh3)3]在酸性环境下倾向于生成[RuHCl(PPh3)3]物种，该Ru-H物种对C=C双键加氢反应表现出较高的活性；而碱性环境下则易于生成[RuH4(PPh3)3]物种，该Ru-H物种对C=O双键加氢具有较高的催化活性。

The results of the investigation showed that the best entrance angle of B〓C, B〓C/ C and Al〓O〓/ C ceramic nozzles is 11°, 14°and 16°respectively. Erosion wear model has been put forward. The B〓C and B〓C/ C nozzles exhibited a stress fatigue induced removal process under the condition of umber emery erodent impacting, and a brittle fracture induced removal process under the condition of white emery and SiC erodent impacting.

建立了不同磨损机理下的冲蚀磨损模型，提出了喷砂嘴的磨损属于多冲蚀机理并存的复合冲蚀机制。B〓C和B〓C/C陶瓷喷砂嘴在棕刚玉磨料的冲蚀下，主要表现为应力疲劳断裂冲蚀，在白刚玉和SiC磨料的冲蚀下，主要表现为脆性断裂冲蚀。

A C-C bond type radical initiator i.e. 1,1,2,2-tetraphenyl-1,2-ethanediol and a S-S bond type thermal iniferter, i.e., tetraethyl thiuram disulfide were used to consist of new reverse ATRP initiation systems TPED/FeCl3/PPh3 and TD/FeCl3/PPh3, respectively."Living"/controlled polymerizations of a polar monomer MMA and a non-polar monomer St were investigated with the initiation systems as well as other new initiation systems; behavior of vinyl polymerization with a new asymmetrical C-C bond type thermal monomeric iniferter was studied also.

前者选用C-C键型的自由基聚合引发剂1，1，2，2-四苯基-1，2-乙二醇、S-S键型的热iniferter二硫化四乙基秋兰姆组成新引发体系TPED/FeCl3/PPh3、TD/FeCl3/PPh3，研究这些引发体系引发MMA、 St聚合的&活性&/控制聚合行为，同时研究一些其他新引发体系；后者合成了一种新的非对称C-C键型热引发转移终止剂，并研究其自由基聚合规律。

The French and Italian poets gave preference to the Italian form of sonnet—two groups of four lines, or quatrains (always rhymed a-b-b-a a-b-b-a) followed by two groups of three lines, or tercets (variously rhymed c-c-d e-e-d or c-c-d e-d-e)—which created a sonorous music in the vowel rich Romance languages, but in Shakespeare it is artificial and monotonous for the English language.

法国和意在利诗人优先使用意大利格式的商籁诗----两组四行诗（总是按a-b-b-a a-b-b-a的格式押韵）加上两组三行诗（按c-c-d e-e-d或 c-c-d e-d-e格式押韵），这就在元音丰富的罗马语言中产生了一种感人的音乐节奏，然而放在莎士比亚的英语作品里，就变得矫揉造作和枯燥单调。

Do you know, i need you to come back

你知道吗，我需要你回来
