链

The same number is associated with all uplinks and induced uplinks associated with the outside link.

Consequences of the rotation of DNA are illustrated in Figure 9.17 in the twin domain model for transcription. As RNA polymerase pushes forward along the double helix, it generates positive supercoils ahead and leaves negative supercoils behind. For each

超螺旋与转录还有更多的关系，RNA聚合酶转录DNA时，解链和复链同时也发生，如同Fig113中所示，这需要整个转录复合体绕DNA旋转或者DNA自己绕它的双链轴旋转，DNA旋转的后果如Fig11.19所示，图中是一个转录的双结构域模型，当RNA聚合酶沿DNA前移时，在酶前产生正双螺旋，酶后为负的双螺旋；每一个双螺旋转角被RNA跨越后都会在前面产生+1转角，后面产生-1转角。

We want to buy Chains, Chainwheels Automotive Chains and Sprockets

我们要采购链，汽车链和扣链齿

However, because of the chain drive and the capability to alter the chain direction using sprockets, the conveyor pathway can have turns in its continuous loop.

然而，因为链驾驶和能力改变使用扣链齿的链方向，运送装置路能在它的连续环中有旋转。

At first monotone chain of polygon is spaned in the new algorithm. Second, the nonregular vertices are sorted by Y-coordinate. At last active monotone chain is established and filling of polygon is finished .

新算法首先生成多边形单调链，并对单调链尖点按Y坐标排序，最后建立活性单调链表，从而完成多边形的填充。

Combination Rodes: A good compromise between all-nylon or all-chain rode is to use a short length of chain (6'-30') connected to the anchor, with a long length of three-stand nylon line connected to the chain.

锚链和锚缆绳结合型：有一个好的折衷的方法就是用一截短短的锚链(6'-30')连接到锚上，然后用比较长的&三股&尼龙绳接到锚链上。

The binding of different halide anions to four strapped calix[4]pyrroles was studied by means of molecular mechanics and molecular dynamics simulations methods. The results indicate that the anion binding ability of calix[4]pyrrole-type systems could be effectively tuned by modifying the length and nature of the bridging straps. In this process, it was the most stable conformation upon anion binding due to the formation of four NH\|halide hydrogen bond, simultaneity, the difference of cavity by modifying straps adapted themselves to different halide anion.

模拟结果表明，加入带状修饰链和调节链长可以增强对某种特殊卤素阴离子的识别，在这个过程中，卤素阴离子与杯[4]吡咯NH上的氢形成的多氢键使主体分子与阴离子形成稳定复合物，同时带状修饰链通过改变杯吡咯空腔大小影响主体分子与卤素阴离子的氢键相互作用，从而调节了对不同阴离子的识别能力。

To overcome the above described drawbacks,P.W.Baier and other researchers propose a novel multi-user transmission scheme for the downlink of TD-CDMA termed joint transmission. This paper discusses the application of JT technology in the FDD system,and proposes a new solution: Through feedback signal,channel pre-estimation is accomplished at the base station.

为此提出了名为联合传输的多用户传输方式，可以利用TDD模式上下行链路移动无线信道脉冲响应相等的优点，只在上行链路对信道进行估计，下行链路利用估计得到的信道冲击响应值，把在移动台判决传输信号的任务交给基站来完成，利用这种技术可以提高系统性能和减少系统复杂性。1系统模型及JT原理联合传输技术[1～3]，可由信道传输概念引出，如图1所示。

In this paper, the flux oriented angle of stator flux oriented vector control is deduced by the voltage vector space angle of the direct torque control, and mathematical model is set up based on the direct and quadrature axis component of the stator current.

将直接转矩控制与定子磁链定向矢量控制相结合，利用DTC中电压矢量的空间位置角，推导出SFOVC中的磁链定向角，然后根据旋转坐标系中的d轴和q轴电流分量，建立定子磁链估计的数学模型。

Roller chain is a type of important moving parts. Drill the spreading of machine to move the system inside in the petroleum, chain drive of diesel engine to the car is belong to typical model the work to roller chain at high speed.

滚子链是机械中重要的传动部件，在石油钻机的传动系统中，柴油机并车链传动属于典型的高速工作滚子链。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
