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。

SCN quantity and size in the carding process were tested by using AFIS tester under following conditions, carding machine used different doffer,taker-in, speed and different types of taker-in, carding machine back sheet used stationary flat, web cleaner and carding segment .

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 submergible control platform width was positively related with the diameter of cage framework. The relation was k=1-2+22r-h_4~2+14l~2+12r~2-22rl, in formula h_4 was the platform height, which was restricted by the water depth. There h=h_1+h_2+h_3+2h_4+12H, in equation h_1 stood for net sheepshank height, h_2, the height of gravity setting on the bottom net, h_3, the distance from gravity setting to submarine, H was estimated maximal wave height while typhoon occurred in cage areas.

控制平台的宽度l与网箱主构架半径r正相关，设计时必须满足网箱框架外侧与平台的距离k大于零，其中：k=1-2+22r-h42+14l2+12r2-22rl，h4为控制平台高度，其受放置区水深h的制约，高度与水深的关系：h=h1+h2+h3+2h4+12H，h1为网衣缩结高度，h2为网衣底部重力装置高度，h3为重力装置到水底的距离，H为网箱放置区台风期预计最大波高。

Gecko danger, to escape from the end, the tail can also regeneration; spiders can not only foresee the impending storm front, but also quickly erect个Net knot to prevent cross-Net torn by wind and rain and no home to return to; fly bats were not birds belong to animals, it can rely on their own issued ultrasonic reflectivity of the target to determine the target insects are still obstacles; sundew, rainbow grass these plants were able to "kill" small insects as their own "food"......

壁虎遇到危险，脱尾逃生后，尾巴还能再生；蜘蛛不但可以预知暴风雨来临，而且还赶忙结个竖网，以防横网被风雨扯破后无家可回；会飞的蝙蝠居然不属于鸟类动物，它还能靠自身发出的超声波对目标物的反射来确定目标是昆虫还是障碍物；毛毡苔，彩虹草这些植物居然能"捕杀"小虫子作为自已的"食物"。。。。。。

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。

Effect of F(superscript -) on structure and properties of vitrified bond was analysed.

结果表明：在低熔陶瓷结合剂中引入适量的F可以降低结合剂的耐火度，提高结合剂对CBN的润湿性以及结合剂本身的抗折强度。F在玻璃网络中起断网作用，因此F加入量不能大于5%，否则会影响结合剂的综合性能。
