查询词典 windmilling

Techniques for model structure choose via Parsimonious Genetic Programming were proposed, and a model to estimate engine windmilling starting characteristics based on PGP was brought forward.

以某型涡喷发动机为对象，在给定条件下，运用所建立的模型对该型发动机的风车起动过程进行了模拟，得到了起动性能的仿真结果。

He dangles wildly upside-down for a moment, arms windmilling, then gets his hands pressed firmly against the opposite wall.

In order to solve the problem of engine starting characteristics calculation under windmilling condition, a generalized format of engine starting nonlinear mathematical model based on liner-in-parameters model was given.

针对高空风车条件下航空发动机起动性能估算问题，给出了用线参数模型描述发动机风车起动非线性过程的一般形式，利用约简遗传规划算法进行模型结构选择的思路，建立了基于约简遗传规划的航空发动机起动性能计算模型。

You're in the batter's box when the 6-ft., 1 in. pitcher unleashes a bundle of blonde fury: whippet arm windmilling across the mound, ball screaming toward the plate at some 65 m.p.h. Because of the short, 40-ft. mound distance in softball, that's like trying to hit a 90 m.p.h. pitch in baseball. Swing and a miss.

当你在击球区看着一位六尺一英寸的投手释放出金色美女的激情：她轻盈的臂膀在投手土墩（mound：投手所站在的小高地）旋转，球以65英里/小时的速度呼啸着向垒板而来，因为垒球中土墩距离只有40英里，65英里/小时速度这棒球里相当于90英里/小时。

The gas turbine engine windmilling is a state that when the engine doesn t work,the rotors temporarily operate at a sub-steady rotating speed due to the airflow ram and the co-work of aerodynamics,rotor inertia and drag torque.

由于很多燃气涡轮发动机都缺乏计算风车特性必需的低转速状态的部件特性，给计算发动机风车状态的特性带来了很大的困难。

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
