查询词典 permanent field

Delineation result based on the improved ant clustering indicated that the study area could be partitioned into two irrigation management zones. Soil field capacity, saturation moisture content and permanent wilting point in Zone I were greater than those in Zone II, which indicated that soil in Zone I had stronger drought resistance than that in Zone II under the same climate conditions. Delineation of irrigation management zones could provide references and data support for site-specified irrigation management.

改进的蚁群聚类分区结果表明，研究区可划分成2个灌溉管理分区，I区土壤的田间持水率、饱和含水率和凋萎含水率均较II区大，表明在相同的气候条件下，I区的土壤耐旱能力较II区强，分区结果可以为精准灌溉的分区管理提供参考依据和数据支持。

A new six-phase disc permanent magnetic synchronous motor which adopts a one-rotor-two-stators configuration was designed. The structure and characteristics were presented . And the design method and parameters were calculated .FEM is used to analyze the magnetic field characteristics of this motor.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

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。
