The Y-TZP nanoceramics with an average grain size of 60 nm and a relative density of 98% were prepared by pressureless sintering.

采用无压烧结获得了相对密度为98%、平均晶粒尺寸为60nm的Y-TZP纳米陶瓷。Y-TZP纳米陶瓷的显微硬度主要取决于陶瓷的相对密度、相结构和晶粒尺寸，即陶瓷的四方相质量分数越高，相对密度越大，晶粒尺寸越小，则显微硬度越高。

The Lithostegia Ching was considered as a member of Peranemaceae for a long time, according to the research,we found that it has the typical scalariform perforation plates,no associated or crossed phenomena,and some region have intact plate,no dimorphic phenomena,no weblike or threadlike remnants,these suggest that The Lithostegia Ching is in a primal evolutional position.

与传统观点不同，我们认为穿孔板仅存在于端壁的管状分子为导管分子，而端壁和侧壁形态、结构相似，有或无穿孔板的管状分子为管胞，蕨类植物中的管状分子主要为管胞。

In studies of the aging of the homopolymerization and the copolymerization of emulsion, it was also found that the stability of the soapless polymer particles has an intimate relationship with the method of preparation, the structure and quality of the comonomer.

通过对均聚和共聚乳液进行静置考察，发现无皂高分子胶乳粒子的稳定性与制备方法、共聚单体的结构及性质有著密切的关系。

SO3 is fixed in ashes at 850~900℃, and it exists in Ⅱ-CaSO4 and has different solubility with the natural anhydrite and the plaster calcined at 400℃. It is the first time to prove that the particles of f-CaO is coated withⅡ-CaSO4 by investigating the process of forming f-CaO, the microstructure, spathic type and optic parameter and the hydrating process.

首次从f-CaO的形成过程、颗粒微观结构、晶型和光学参数以及水化历程等方面证明了f-CaO颗粒被固硫产物无水硫酸钙包裹的颗粒特征，f-CaO颗粒被Ⅱ-CaSO4包裹使其水化速度减慢和活性较低；SO3以Ⅱ-CaSO4形态存在和f-CaO颗粒被Ⅱ-CaSO4包裹均对流化床燃煤固硫渣的活性和体积稳定性产生不利影响。

Except for the good spumescence and decontamination, it possesses the bioactivity of antigen and antitch. First of all, the high resolution mass information was obtained by ESI-QTOF. Hence the possible molecular formulars were acquired too. Then we conducted the further detection of the structures of its saponins by using ESI-IT technology.

中的皂苷成分，由ESI-QTOF得到各个皂苷成份的高分辨质量数据进而得到其分子式，然后利用ESI-IT电喷雾串联质谱对无患子总皂苷中各皂苷成分的结构进行进一步的鉴定。

These concurrent running computations share a set of refine-grained atomic synopses which can be composed of a synopsis for a computation. Because of the refined grains, redundant information between coarse structures can be eliminated.

因此，本课题提出计算集算法复杂度来度量并发计算的复杂度，提出可以在多个计算间共享的细粒度和无信息冗余的原子概要结构。

In this dissertation, several novel halogen-free fire-retardant epoxy-based copper clad laminates were developed. Two kinds of phosphrous-containing epoxy resins were synthesized by different method. A novel nitrogen-containing curing agent 2,4, 6-tri (phenol-methylene -amide)-trizone was synthesized for preparing high-performance epoxy polymers, and the synthesis kinetics, cure kinetics and mechanism of MFP cured with DGEBA have been investigated by Differential Scanning Calorimeter and in situ Infrared.

本论文以开发新型无卤阻燃环氧树脂基覆铜板为目标，合成了两类结构不同的含磷环氧树脂以及一种新型的含氮固化剂2，4，6-三-均三嗪，考察了它们合成过程中的影响因素，用DSC和原位红外光谱法探讨了MFP固化环氧树脂的固化反应机理。

Thus by studying the unconsciousness of culture we can further understand the undividable dialectical relations between culture and man and the important recessive factors in the structure of the main cultural spirit and cognition as better to discipline man's behaviors and understand man himself.

通过研究文化无意识，可以使我们更好地理解文化与人之间密不可分的辩证关系，以及文化主体的精神和认识结构中重要的隐性因素，从而更好地规约人的行为，更好地理解人本身。

Through optimizing the parameters of the impact mechanism and using of the result above, the optimum result on the impact mechanism is obtained, which has had practical consult value to design valveless hydraulic drill.

利用仿真研究的结果，对影响冲击机构的物理参数和结构参数进行了优化，得出了优化结果，对于无阀液压凿岩机的设计具有实际参考价值。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
