Six years at Milan, then, for the European Champion coach, who aside from the Scudetto also obtained two second places in Serie A, after two exciting title races decided only on the final matchdays, a third place and two fourth places , the first after coming on when the season had already begun, and the second because of an unjust penalisation.

It respectively constructs quasi projection-separation facet sets of two convex polytopes while their orthogonal projection on the centerline overlap mutually. Afterward it judges the separation of two convex polytopes by confirming non-overlap in orthographic projection on the centerline or by finding out a projection-separation facet from two quasi projection-separation facet sets, otherwise a collision is judged.

该算法通过判断2个凸多面体在中心线上的正投影不相交，或者分别构造它们的准投影分离面集合，并从这2个集合中找到一个投影分离面，来判断2个凸多面体分离；否则，判断为相交。

However, when two maturing oocytes fused and two spindle will form in the big cell, the chromosomes will not intermingle. In the present study, we removed GV from one oocyte and transfer to the perivetelline space of another GV oocyte. After fusion the resulting oocytes which contained two GVs were cultured further in MEM.

在本实验中，我们利用小鼠GV期卵母细胞将一枚卵母细胞的生发泡取出后移至另一未经去核处理的GV期卵母细胞透明带下，经三次电脉冲作用后将融合的含有两个GV的卵母细胞放入MEM成熟培养液中培养，在培养成熟的不同阶段分别收集卵母细胞进行免疫荧光染色观察微管及核的变化。

The new rT joint not only has two rotation axes that intersect at right angle,but also has another rotational degree of freedom which can be used to modify the assembly of other joints.This can change the mobility of the parallel mechanisms that assembled with the new rT joints and leads to two types of metamorphic paralllel mechanisms:In the first type,the mechanism changes its topology by turning the new rT joints in all limbs into different configurations which reconfigures the constraints within the limbs or the assembly of all the limb constraints.This change of mobility is completed by two cases.One is illustrated by a 3PS and a 3C parallel mechanism,by altering the rT joint into different configurations there will produce or reduce local degrees of freedom and thus change the constraits to the moving platform.This qualifies the 3PS and 3C to have variable mobility from 3 through to 6 and from 1 through to 6 respectively.

该铰链除了一般Hooke铰的两个轴线互相垂直相交的旋转自由度外，还增加了一个可以调节该两个轴线之一的姿态的一个旋转自由度，通过此自由度调节该rT铰到不同的装配构型，可以改变用其装配的并联机构的自由度，由此产生两类新型的并联变胞机构：一类是机构的各个支链中都有rT铰，该铰链的不同构型可以改变各支链对运动平台的约束或整个支链组的组合形式而改变机构的自由度状态，3PS和3C属于前者，通过调节rT铰到不同构型可以使其支链产生或消失局部自由度，从而减少或增加支链对运动平台的约束，使得并联变胞机构3PS和3C分别具有自由度从3变到6和从1变到6的能力；3P属于改变支链组组合形式的机构，其rT铰的不同构型将改变整个支链组的几何约束组合，使得并联变胞机构3P可以有三转动、三平动或三平移(来源：ABCded9de论文网www.abclunwen.com)一转动的自由度形式。

The morphological structure of cured vinyl-ester resin and the formation of two-phase structures in vinyl-ester resin has been studied by using SEM and differential scanning calorimetry.The results demonstrated the existence of clusters of gel-particles with a size of about 20 μ m,each cluster of gel-particles containing many gel-particles with coral-like structures.The formation of gel-particles resulted in two-phase structure characterized by the two peaks in the rescanned DSC thermographs of the resin. The cure conditions (temperatures,post-cure) affected microstructure in the cured resins.

采用SEM、DSC研究了乙烯基酯树脂固化过程中凝胶粒子的形成过程及两相结构对固化放热的影响，结果表明，凝胶粒子在固化树脂中呈群状分布，每群凝胶粒子的最大尺寸为20μ m左右，每群凝胶粒子由许多独立凝胶粒子组成；凝胶粒子的形成使树脂产生了两相结构，使树脂的恒温DSC残余放热呈双峰分布；树脂的固化条件影响其微观结构。

My brother is in patients with cerebral cysticercosis has been five years, and last year found that cysticercosis, long before the do not know what things are when infected rule, today's one-year ate insecticide, I may be the words a little wrong, this year, made only two diseases, much better than before, and last week we go to a professor of film to see says Well, my dad did not believe a little bit and took it to the film to my sister's classmates (Wuhan Union Medical College Hospital where he is a special film's) found in the brain, he said the middle of a long one, and the former are not carried out, and now that long special that does not look good inside, this time to come back took five courses of medicine, but on the third day of his return had a grand mal, morbidity, and as before, the body twitching, mouth spit things, but not before the head pain, unable to speak of this headache, and go to an intravenous drip to fight two days of talent is good, could not eat anything for two days, three days before eating a bowl of porridge,(this time his hands have not felt feet, as if pressed to the people, and nearly died), doctors now we I really do not know how to do, please kindly help us, your home bar, help my brother, help my father, my mother, but they just really tired, and five years, they have never slept a day better, you are cures of these diseases, you know that this disease attacks together is really scary, so please help us bar

我弟弟是脑囊虫患者已5年了，去年才查出是囊虫，之前不知道长的是什么东西，都是当感染治的，今天一年吃的是虫药，可能我的字有点错，今年一年只发了两次病，比以前好多了，上个星期我们又拍片去给教授看教授说好了，我爸有点不信，又把片子那去给我姐的同学看(他是武汉协和医院里专门拍片的)他说发现在脑中间长了一个，以前的全都没有了，现在那个长的特别内面一点不好看，这次回来拿了五个疗程的药，但是就在回来的第三天他大发作了一次，发病和以前一样，身体抽动，口里吐东西，但以前头不痛，这次头痛的不能说话了，去打点滴打了两天人才好，两天什么都吃不下，第三天才吃了一碗粥，(这次他的手的脚都没有感觉了，好像压到人中了，差点死掉)，医生现在我们真不知道该怎么办了，请好心的您帮帮我们家吧，帮帮我的弟弟吧，帮帮我的爸爸，妈妈吧，他们真的好累了，5年来，他们从没有一天睡好过，你是专治这些病的，你也知道这个病发作起来真的很吓人，所以请你帮帮我们吧
