使融合

On the morphological differentiation,by inducing of fetal calf serum,it wasshown that the cytotrophoblast cells underwent aggregation first,and the adjacentcytoplasm membranes became tightly contacted through desomosomes andcytoskeleton.Then the adjacent cytoplasm membranes disintegrated fragmentallyto form fusion pore-like structure.Finally the multinuclear cells formed and inwhich the intercellular desmosomes disappeared.Immunocytochemical stainingfurther demonstrated that the formation of syncytium was through cell membranefusion rather than the amitosis process.

细胞形态分化的研究结果表明：早孕胎盘来源的细胞滋养层细胞在血清诱导下，首先发生聚集，并通过桥粒和细胞骨架使相邻的细胞膜紧密接触；之后细胞膜发生片段断裂，形成融合孔样结构；细胞间桥粒消失，最终形成多核的合体细胞；免疫细胞化学分析进一步证实合体化是通过细胞膜融合而非无丝分裂（amitosis即细胞核分裂而细胞质不分裂）实现的。

Apomixis provides a unique opportunity to fix and utilize hybrid vigor. A number of research programs around the world have tried to use apomixis as an important plant-breeding tool.

无融合生殖是指不经过雌雄配子融合而产生种子的一种特殊生殖方式，能使基因型的杂合性得以保持，从而可以固定杂种优势，对作物育种具有极其重要的意义。

We've got to take that, we've got to make that into a fusion reactor. Because we want 30 million years worth of fusion power for the Earth. This is the device we're building now.

我们必须做这些，我们必须使它成为一个核融合反应炉，因为我们希望为地球获得相当於三千万年的核融合能，这是我们正在建造的装置（ITER：国际热核实验反应炉）。

Presents the design of longitudinal control for ASTOVL lift-fan aircraft, a multi-variable, strong-coupling, complicated nonlinear system to make the system nonlinear offset and decouple, and the method used for linear system in designing the system to gain expectant flying qualities and the combination of aerodynamic control surfaces with thrust vectors to delay the control surfaces getting into saturation, and the minimum N-norm generalized inverse theorem of weighted generalized inverse adopted to apportion the moments commands, which make the control surfaces gain appropriate deflection and the simulation results to verify the dynamic inverse control laws designed really make the system nonlinear offset and decouple; when one command is given, only this output will response, and others do not response; when all commands are given together, the responses will be just the linear superpose of the response of each command, therefore the operation of the pilot will be simplified greatly.

摘 要： ASTOVL升力风扇飞机是多变量、强耦合、复杂的非线性系统，采用非线性动态逆理论设计控制律以实现系统的非线性对消及解耦，然后，采用线性系统的设计方法对系统进行设计，以使系统获得期望的飞行品质。同时，考虑到ASTOVL升力风扇飞机是由气动舵面和推力矢量融合作用的，为了延缓各舵面进入饱和的时间，采用加权广义逆中的极小N-范数广义逆定理分配力矩指令，从而使各舵面达到适当的偏转角。并将所设计的控制律进行了仿真，结果验证了所设计的动态逆控制律使系统实现了非线性对消和解耦，单个指令作用时，只有该项响应，其余不受影响；所有指令作用时，其结果就等于单个指令作用时的线性叠加，这样使驾驶员的操纵大大简化而易于控制，从而大大降低了飞行事故率。

Then false color image and panchromatic image are fused by IHS and wavelet transform to retain more detail information.

同时将伪彩色映射融合后的图像进一步用IHS变换提取空间信息，在小波变换框架下将其与全色图像进行融合以提高目标的边缘细节信息，使所获得的融合结果不仅包含丰富的光谱信息的同时还具有较高的空间分辨率。

The synthesized cDNA is a continuous band less than 6. 0kb shown on x-film through α〓PdCTP which was inserted in the first strain of cDNA. The titer of the Ha-cDNA library was about 1. 5×10〓cfu/ml which could represent all protein-encoding sequences from Hz-AM1 cells; Namely, the cDNA library has representativity. After the successful construction of the Ha-cDNA library, the open-reading frame of vp39 gene of Heliothis armigera was then fused in frame with the Ga14-DNA-binding domain in the pGBT9 plasmid and the fusion protein Ga14-VP39 was expressed in yeast to be used as bait protein.

Aligned cells are electroporated and subsequently electrofused within high electric field strength.

细胞电融合利用细胞在相对电极之间的介电电泳，诱导细胞按特定方向排列，通过电极间产生的较高场强的电脉冲使相互接触的细胞发生电穿孔，进而发生电融合。

It tries to and should mix and fuse poetry and prose, inspirition and criticism, the poetry of art and the poetry of nature; and make poetry lively and sociable, and life and society poetical; poeticize wit and fill and saturate the forms of art with every kind of good, solid matter for instruction, and animate them with the pulsations of humor.

浪漫主义诗歌试图并理应融合诗与散文，融合瞬间灵感与理性批评，融合人工雕琢之作与自然天成之品；应该使诗充满生机令人喜闻乐见，给生活与社会点缀诗意；应该令才智富含诗情，用旨在教益的各类善的、坚实的素材充实各样艺术形式，展现艺术家个性以令这些艺术形式焕发蓬勃生机。
