查询词典 in rotation

The results indicated that the transfer and loss of N and P vary with means of rotation, types of crops and the amount of fertilizer application. Buffering forest belts betweens farmlands and ditches can effectively stop and purify such elements as N and P in soil runoffs, thus controlling non-point source pollution of agricultural lands.

结果表明：农田生态系统中 N、P等迁移、淋失状况随轮作方式、作物种类及施肥状况而变化；农田与沟渠间的缓冲林带具有截留和净化土壤径流中的N、P等物质的作用，从而在一定程度上控制农业非点源污染。

如果是小口径的管道－ 4英寸或者以下－将管道旋转四分之一圈，确保粘合剂在结合面上分布均匀；如果是大口径的管道－大于4英寸－旋转会非常困难，也不现实。

The plastic go down the hopper smoothly and is gripped by the thread of the screw. It is forced to go toward the direction of the gear end along with the rotation of the screw. A mechanical transferring process is formed. During the running of the plastic from the feed port to gear end, a high pressure is formed in the process of plastic curing due to the gradual decreasing of the thread depth and the resistance of filter gauze, splitter plate and gear end. The high pressure helps to press the raw material and improve its heat conductivity performance and the quick melting of the plastic, at the same time, the gradual increasing pressure can help the gas which is among material particles exhausted from the air holes.

在压力升高的同时，塑料一方面被外部加热，另一方面塑料本身在压缩、剪切、搅拌的运动过程中，由于内磨擦力也产生了大量的热，在外力和内力的联合作用下，塑料温度逐渐增高，其物理状态也经历了玻璃态--高弹态--粘流态的变化，一般地说来，在加料段中主要是玻璃态，在螺杆螺纹逐渐减少的中间部分压缩段中，物料主要处于高弹状态，同时也逐渐的熔融，而物料到压缩段后部和化段作用处于粘流态了，这时我们称塑料已完全塑化了，由螺杆推力作用将塑化的塑料定压定量的从机头中挤出。

A neoclassical ion heat transport coefficient model is adopted, in which the effect of sheared poloidal rotation is taken into account, and the heat flux function has multiple values with the same plasma density and temperature.

采用考虑了剪切极向转动效应的新经典离子热输运系数模型，这种模型导致的热通量函数在相同的密度和温度下是多值的，将它用于电子与离子之间有碰撞的MHD方程，数值结果显示了H模情形等离子体上边缘陡峭的离子温度梯度。
