The concept of "typhoon":Some subjects lacked clear concept about the density of isobaric line of the typhoon, and the processing route, the weather situation of the typhoon eye and the icon of the typhoon on the weather map.

认识台风：部分学童对於等压线越密集台风的风速越大，台风的行进路线、台风眼的天气情形以及天气图上台风的图示，均欠缺清晰的概念。

LSD new type crimping tools adpots the best lever principle to effectively design the handle,although its structre is short and, the operation is very laborsaving when crimping wire of larger cross section Applicable for non-welding, complied with the standard electrical connection.

压线钳 因为压接范围不同，手动压线工具有：产品系列：LY、L、S、P、A、LS、AN、HS、DN、AP等压线钳系列；压著钳举例LY 系列： LSD 新型压线钳，采用最佳杠杆原理对手柄进行有效的设计，虽然结构非常短小紧凑，但操作时，尤其在压接较大横向联合截面的导线时，非常省力。

A region of low pressure with roughly concentric isobars is known technically as a cyclone.

具有大致同心的等压线的低压区在技术上称为气旋。

Isotherms 43 and isobars 44 are even more important than their names sound.

等温线」和「等压线」听起来比它们的名字还要重要。

In the method of improving ship forms by the combination of Guilloton′s method and the elastic net method, Guilloton′s transformation is used to find the isobars on the improved ship surface.

在Guilloton法和&弹性网格法&相结合的船型改进方法中，首先用Guilloton的船型改进方法求出船型的船侧离散等压线点。

The wind directed inward around the center makes angles of 20o to 40o with the isobars.

围绕中心向内吹的风与等压线构成20o --40o的夹角。

The atmospITe prescertain gradient is an inverse meacertain of the spacing of the isobars on a weatIT map.

气压梯度与天气图上等压线的间隔大小成反比。

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。
