Low Voltage AC system operating voltages from 120 to 600 VAC.

低压 交流电系统中从120到600 VAC的电压称为低压。

Using p-T pseudosections with contours of H20-contents, the medium-low pressure metamorphism for pelite from the Altai orogen was documented. We proposed that the andalusite-type metamorphic zones in Altai were related to the uplifting of kyanite-type zones and are characteristic of isomorphic transformation between aluminosilicates. Generally, it is difficult for the low-pressure metamorphic assemblages to reach an equilibrium state.

利用p-T视剖面图和饱和水含量等值线的行为研究阿尔泰造山带泥质岩石的中低压变质作用发现，阿尔泰地区红柱石型变质带的发生与蓝晶石型变质带的抬升有关，主要发生铝硅酸盐矿物之间的同质多相转变，低压变质矿物组合未能达到热力学平衡状态。

Meanwhile ,this paper analyzed separately the relations between Atlantic high pressure,Ice landic low pressure and our country's climate.Results showed that winter tempera ture in our country was correlative with Atlantic high pressurepresented basical ly, but counter-correlative with Icelandic l...

同时，还分析了大西洋高压和冰岛低压与我国气候的关系，发现大西洋高压与我国冬季气温基本呈正相关，而冰岛低压与我国气温大致呈反相关，但均没有显著影响，所以两者都不是影响我国气候变化的重要天气系统。

The ruthenium catalyst has high activity at low pressure, so it suitable for low-pressure ammonia synthesis.

但钌催化剂具有较高的低压活性，适宜低压合成氨。

In this thesis, soft starter equipment realized by thyristors power transform circuit is studied. To improve equipment performance, we apply variable reactance technique to AC motor soft starter study. The high voltage AC working winding of reactance is in series with motor winding, while low voltage control winding and thyristors groupware with intelligent controller constitute close loop circuit. We adopt thyristor phase control voltage-regulator mode to control low voltage winding, then control the reactance of high voltage winding, and then arrive at the goal-control the current and voltage of motor AC to realize motor soft starting.

本文研究由晶闸管功率变换电路实现的软起动器装置，为了提高装置的性能，将可变电抗技术应用于交流电机软起动研究中，电抗器的高压交流工作绕组与电动机绕组串接，低压控制绕组与带智能控制器的晶闸管组件组成闭合回路，采用晶闸管相控方式控制低压绕组，从而控制高压绕组的阻抗，以达到对电机电流与电压的控制，最终实现电机软起动的目的。

And 0.64±0.05GPa for sillimanite zone, 750～800℃ and 0.9～1. 0GPa for partial melting migmatites. The results generally show that the kyanite sequence metamorphic belt is a normal medium-pressure sequence.

十字石带有后期向低压转变的趋势；矽线石带的变质条件比中压型正常正常演化条件低，这可能是保留了后期向低压转变的特点。

Within pelitic metamorphic rocks, even though sillimanite is well developed and the low-pressure minerals like andalusite and cordeirite etc.

新疆阿尔泰古生代造山带以低压变质及花岗质岩浆作用广泛发育闻名国内外，泥质变质岩系中矽线石较发育，红柱石和堇青石等低压特征矿物相当常见，但是，石榴石—十字石的组合更普遍。

Based on the characteristics of LPS and solar energy power, a new 55W low pressure sodium lamp electronic ballast is developed.

基于低压钠灯和太阳能供电的特点，研制了55 W新型太阳能低压钠灯电子镇流器。

Until the third stage, when subtropical high retreats completely from the SCS and the low pressure system over southern China moves southeastward and embeds itself in the low pressure zone over the northern SCS, strong tropical southwesterly flow brings in ample amount of moisture and causes moisture convergence over the southern SCS under the influences of the low pressure zone. Deep convections bloom due to sudden increase of low-level convective instability.

一直到第三个阶段，太平洋副热带高压完全退出南海，而华南低压中心移入南海北部的低压带，与强盛的热带西南气流结合，在南海南部形成强烈的西风与大量的水气集结，低层对流不稳定度快速增加，以致於产生旺盛的对流。

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。
