The forward kinematics is analyzed by choosing one of the mechanisms which have one, two,three or zero angle constraint.Wherein,3-CCC is a new parallel mechanism which has three angle constraints and three distance constraints, Calay\'s formular and direction cosine matrix are used to describe the rotation matrix respectively.By setting Dixon\'s and Sylvester\'s resultant with the three angle constraint equations respectively and using parameters replacement to deal with the distance constraint equations,the 64 order input-output equation of the forward kinematics is obtained under both of the methods.Numerical example confirms these theretical results and the motion simulation is shown in VC++ by integrating OpenGL.

3对高小山提出的广义并联机构进行了研究，以其中具有角度约束的并联机构进行了分析，选取具有一个、两个、三个和零个角度约束类型中各一个机构进行了运动学正解求解，其中3-CCC是一种全部由圆柱副构成的具有三个线线角度和三个距离约束的新型并联机构，文中分别用Calay公式和方向余弦两种旋转矩阵建模方法对其位置正解进行了分析，通过对三个角度约束方程分别构造Dixon结式和Sylvester结式，以及对三个距离约束方程进行变量代换分别导出了位置正解输入输(来源：4040ABC论文网www.abclunwen.com)出方程，得出64组位置正解，并使用数值算例验证了其全部根。

On the other hand, the mirror's ink attracted of moisture in the air, the business card printing and membership card after the mirror effect is not good, to do this, in business card printing and membership card making, mirror ink poured into the screen must be mensurated business card printing and membership card production, in order to complete a smooth business card printing and membership card production, that is, the edge business card printing and membership card production boundary check work piece rate, will give business card printing and membership card making impact effects, such as the heightof, qpart, ink stencil slagging on tours.

另一方面，镜面油墨易吸收空气中的水分，制卡和会员卡制作后得到的镜面效果不好，为此，在制卡和会员卡制作时，镜面油墨倒入网版后必须连续快速制卡和会员卡制作，才能完成顺利制卡和会员卡制作，即是边制卡和会员卡制作边检查工件这种速度，都会给制卡和会员卡制作效果带来影响，例如堵网，油墨印不下去，在网版上结渣团等。

The present paper deals with observation of some sensorystructures (including sensory ncdules and pits on tergum of abdomen) ofadults of 12 species lacebugs of Tingis Fabricius in both sexes,under thescanning electron microscoup,demonstrating the morphological structurecharacters of them and their bearing in classification.

The research of industrial group is the action that discusses a business not just, and the research; that is area whole not only be interior of area of be confined to spin with innovation, and the interior that must pay close attention to area innovation network is outspread with open sex; its content also not network of the industry inside area of be confined to or economic network, the human relation network between the network of informal human relations in society inside area and each one, promoting knowledge accumulate, flow and appreciation, and maintain a respect trustfully to produce tremendous effect.

产业集群的研究不仅仅是探讨企业的行为，而且是区域整体的研究；不光是限于区域内部的结网与创新，而且必须关注区域创新网络的内部延伸和开放性；其内容也不限于区域内产业网络或经济网络，区域内非正式的社会关系网络和各人之间的人际关系网络，在促进知识的积累、流动和增值，以及信任的维持方面发挥巨大作用。

Besides, The nodulation with else host experiment told us that NWGX035 could nodulate with melilotus suaveolens Ledeb, sophora alopecuroides Linn, lotus corniculatus Linn, sophora viciifolia Hance, trifolium repens Linn. The property of powerful salt, alkali, high temperature endurance and wide nodulation could confirm this strain was a particular strain.

另外，回接其它寄主植物的试验表明， NWGX035能与草木樨、黄化苦豆子、百脉根、狼牙刺和白三叶共生结瘤，其广泛的共生结瘤范围和强的耐盐、碱和抗(来源：A9fBC论文网www.abclunwen.com)高温特性可以证明该菌株为一株性状优良的菌株，其共生结瘤机制和耐盐碱机制需进一步研究。

It is believed that if nep number increases during scutching process, the taker-in plays a more active role in eliminating the neps while the stationary flat and web purifier do not.

研究认为：清棉过程中棉结数量增加，刺辊对棉结的去除作用很大，后罩板处加固定盖板和棉网清洁器的作用则不大。

The test shows ——in the condition of specific air capacity, setting only cotton web cleaner can advance yarn forming quality in some degree, and compared to normal back cover guard, evenness CV value of setting cotton web cleaner is reducing by 0.5 percentage point to 0.7 percentage point, thin place is decreasing...

试验结果表明：在一定风量条件下，单独加棉网清洁器对提高成纱质量有一定效果，与后罩板不变相比条干CV值减少0。 5个百分点~0。 7个百分点，细节下降33。 3%~44。 4%，粗节下降16%~24。 5%，棉结下降19。 6%~29。 3%，强力CV也有一定改善；如风量得当，单独加棉网清洁器可起到与加固定盖板相同的作用。

Viciae hurL gene formed nodules in wild-type amounts, indicating that hurL gene is required for nodulation. Although the function of hurL gene in inducing nodulation remains unknown, the results of this work revealed that in addition to the nod and exo genes located on Sym plasmid, the R.

虽然目前对hurL基因影响豌豆根瘤菌诱导植物结瘤能力的机制并不清楚，但本文的研(来源：Acf6fBf6C论文网www.abclunwen.com)究结果首次证明：除位于共生质粒上的结瘤基因和胞外多糖基因外，豌豆根瘤菌在宿主植物上的结瘤还受到染色体基因hurL的控制。
