查询词典 right angle axes

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。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
