正转

Claver says less, character returns to turning

闲话少说，言归正转

Hoisting: Before using the planetary hoisting system, the friction cone clutch needs to be disengaged.

提升：使用行星轮提升系统时，应先脱离摩擦锥离合器，当升降手柄闸紧提升盘时，转筒正转，缠绕钢丝绳，达到提升的目的。

This stage is also known as "countercurrent is being transferred."

这一阶段又称为"逆流正转"。

Because in "the space and time tunnel", the time has the directivity, the invertibility, may the clockwise, may also reverse, but may also relatively static.

因为在"时空隧道"里，时间具有方向性，可逆性，可以正转，也可倒转，还可以相对静止。

The reference and echo signal were separately measured when the hard target was still, in positive rotation and negative rotation.

利用配合目标静止时测得参考信号与回波信号的关系可得参考信号的角度矫正因子为1.1949，使用该矫正因子测得硬目标在正转和反转时转速与真实转速之间的误差小于

The results showed that,the sound pressure level increased significantly when narrow transverse groove was used;the effect of speed on the sound pressure level was greater than loading;the noise of S-shaped straight groove was lower,and the difference of sound pressure level between positive and negative rotation was small;the sound pressure level of 15° oblique groove was higher than 0° and 15° alternate groove,but the difference of sound pressure level between positive and negative rotation of 0° and 15° alternate groove was bigger.

结果表明，无论加刻什么类型的横向细沟槽，声压级都大幅升高；速度对声压级的影响程度大于负荷；在3种类型的横向细沟槽中，S形直沟槽噪声较小，且正、反转时声压级差异小；15°斜沟槽声压级较0°与15°交替排列沟槽略高，但0°与15°交替排列沟槽的正转和反转声压级差异较大。关键词：轮胎；轮胎噪声；胎面花纹；横向细沟槽中图分类号：TQ336.1；TB533+。2文献标识码：B文章编号：1006-8171(2009)

The temporal and spatial variations of the pentad mean surface air temperature have been analyzed in this paper based on the data of NCEP/NCAR from January of 1979 to December of 1995 in the South China Sea monsoon region.

从候平均温度纬圈偏差的时间演变来看，中南半岛地区纬圈温度偏差由正转负的时间早于印度半岛地区，并分别与南海夏季风和印度夏季风爆发的时间基本对应。

It is generally believed that Venus originated with the typical fast and direct rotation. But in the late evolution process, as a result of atmospheric tides and core-mantle friction inside the planet, the rotation is changed gradually. While some others considered that the change of Venus'rotation perhaps due to the early giant planetesimal's collisions.

一般认为，金星原来具有典型的快速正转的状态，在后来的演化过程中，由于潮汐作用或行星内部流体核与幔间的摩擦作用，使得自转逐渐发生变化；也有研究认为可能是早期受到大星子的偶然碰撞所致。

By torque split method and combination of a full-toroidal variator, an epicyclic gear train and a fix-ratio gear, the full-toroidal traction IVT is capable of changing the reduction gear ratio up to plus infinite or minus infinite.

摘要牵引式全环面无限变速器是采用转矩分流方法，把全环面可变耦合器与行星齿轮机构及定速比齿轮机构结合起来，其减速比可以达到正无穷和负无穷，即变速时输出轴可以由正转经零转到反转，因而命名为无限变速器(Infinitely Variable Transmission，简称IVT)。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
