Then the MEMS solenoid type electromagnetic actuating and novel, frictionless and wear-free, and simple structure are designed for fiber-deflecting type MEMS VOA: One of the two coupled single mode fibers is completely fastened in one of the three aligned U-shaped grooves while the deflectable fiber is partially fixed in another groove with a long front section suspending over the wider groove as a cantilever beam. The two fibers, any one for input and the other for output, are well aligned initially so that the insertion loss is very low. Beside the deflectable fiber is a solenoid microactuator with a U-shaped permalloy core attracting a permalloy piece glued on side of the fiber cantilever so that the fiber is deflected and the optical power coupled between the fibers decreased continuously. Using MEMS solenoid as a continuous actuator and the novel structure of VOA are not seen in literature.

为光纤偏移型MEMS可变光衰减器设计了MEMS螺线管电磁驱动方式以及新颖的避免了静摩擦、磨损而且简单的整体结构形式：在硅基片的三段V形槽结构中，将两个对接单模光纤之一完全固定在基片上，只将另一根光纤的稍后部位固定于基片上而使其前端的一定长度悬空，形成一个悬臂梁结构；初始对准后两根光纤之间的光传输损耗很小；通过U型铁芯MEMS螺线管吸引固定于光纤悬臂梁上的坡莫合金片，驱动光纤悬臂梁连续偏移以使两根光纤之间功率传输系数连续变化，从而达到光功率连续衰减的目的。

In 2004 Zhang Zhongfu presented the concept ofadjacent vertex distinguishing total coloring whose content is: Let G be a connectedsimple graph with order at least 2, k be a positive integer and f be a mappling fromV∪E to {1,2,...,k}. Let C={f}∪{f|uv∈E,v∈V}for all u∈V. If (1) for any uv, vw∈E,u≠w, we have f≠f;(2) for any uv∈E, we have f≠f, f≠f, f≠f,then f is called a k-proper total coloring of graph G.

第三章和第四章主要研究了两种联图的邻点可区别全染色，邻点可区别全染色的定义是张忠辅在2004年提出来的，其内容为：设G是阶至少为2的简单连通图，k是正整数，f是V∪E到{1，2，…，k}的映射，对任意u∈V，记C={f}∪{f|uv∈E，v∈V}。

After treated the spinal cord slice at E18 ~ P0 with ChABC at a final concentration of 0.1 U/ml, CGRP-LI fibers in the superficial layers of DH and their branches were seen to extend ventrally instead. When the concentration of ChABC increased to 0.5 U/ml, the above changes were more obvious.

Our project is based on Cenozoic volcanic rocks and deep seated xenoliths in it to reconstruct the source composition and ctructure. We did field investigation, collection of samples, determination of age and composition characteristics of selected samples. The new achievements are following. 1 recognized a potassic metasomatic source of the Cenozoic volcanic rocks through an integrated research of volcanic rocks and their sources. 2 analysis of TM images suggests the Tuoyun basin is a basin with a volcano group instead of a simple volcano-tectonic basin. We found several volcanic craters and cone, and detected three such craters. 3 systematic reseach of volcanic sections and collection of samples both of volcanic rocks and xenoliths, the later includes peridotite, granulite, gneiss and variety of megacrysts. This is propitious to our further research at this rigion. We would like to point that we collected some peridotite large than 20cm in diameter. It could used to variety of analysis and end the history without mantle chemistry records in the region. 4 we got a U-Pb SHRIMP age of 3.87 Ma for the Kangxiwa basalt.It is the youngest record of U-Pb SHRIMP age in China and provide a chronology restriction for last uplifting of Tibet plateau. 5 the investigation of alkali syenite-synogranite in Taxkogan suggests that the origin of Parmir syntex is related to the Cenozoic magmatism.
