The process of shock acted on a vibration and shock isolation system with double-stiffness was divided into two steps. In the shock action phase of a half sine wave, the response was calculated by using a double DOF model. In the free vibration phase, the response was calculated by adopting a single DOF system, the initial displacement and velocity of single DOF adopt the final value of the first phase.

将环境对双模量隔冲减振器的冲击分为两个阶段，在半正弦波冲击作用阶段采用双自由度模型进行响应计算，并以终了时刻的位移和速度作为自由振动阶段的初始条件，对自由振动阶段的单自由度模型进行响应计算。

Influence of Structure of Core Box on Shooting Process ;2. This paper presents how the pressure in core box changes during the shooting process of cold box with a production core shooter.

笔者利用实际生产中所使用的冷芯盒射芯机进行试验，认为冷芯盒的射砂过程可以根据芯盒内的压力变化分为三个阶段：压力上升阶段、压力保持阶段和压力下降阶段。

This paper presents how the pressure in core box changes during the shooting process of cold box with a production core shooter. The influences of shooting pressure and shooting time on the core shooting process have also been studied.

笔者利用实际生产中所使用的冷芯盒射芯机进行试验，认为冷芯盒的射砂过程可以根据芯盒内的压力变化分为三个阶段：压力上升阶段、压力保持阶段和压力下降阶段。

According to the opening or closing spiracle , a typical discontinuous gas exchange cycle has three distinct phases: the closed period with little or no external gas exchange, the flutter period during which oxygen enters tracheae and little CO (2) escapes and the open period during which lots of CO (2) escape.

根据气门开闭，一个典型的不连续气体交换循环(discontinuousgas exchange cycle， DGC)可以明显分为3个阶段：关闭阶段，极少或没有气体交换；颤动阶段，气门迅速微开和关闭， O2进入气管，少量CO2释放；最后是开放阶段，大量的CO2释放。

Design ability is poor, backward technology, small-scale enterprises is very likely, because of the lack of technical and financial resources to deal with export unnumbered.

一些企业表示，名目繁多的贸易壁垒，使得产品在前期获取信息阶段、设计阶段、制作阶段、后期认证阶段都要承担不少的额外费用，大大增加了产品输往欧盟的成本，一些设计能力差、技术落后、规模较小的企业很有可能因缺少应对技术和资金而出口无门。

Because of the regional difference of soil and climatic conditions, the division of 4 stages of soil moisture circulation is not all the same between different areas; the soil moisture dynamics between different dry farming areas in the Yellow River Basin is contrasted in this report. The results indicate that soil moisture increases gradually from dry semi-arid area to semi-arid area, dry semi-humid area and semi-humid area, and the high value district generally appears during soil moisture resuming period in rainy season or soil melting period. While the low value district appears at the stage of fast evaporation in spring or slow evaporation in autumn; in views of vertical changes of soil moisture, it is showed that the variation range of upper lays is larger than that of lower among the different dry farming areas in the Yellow River Basin.

由于各区域之间土壤、气候条件的差异，各地土壤水分循环4个阶段的划分也不尽相同；黄河流域不同旱作类型区土壤水分动态变化比较结果表明：就季节变化而言(来源：A70b0B0bC论文网www.abclunwen.com)，由半干旱偏旱区→半干旱区→半湿润偏旱区→半湿润区土壤水分含量呈逐渐增加的变化趋势，而且高值区一般出现在雨季恢复阶段或春季土壤融冻返浆时期；而低值区均出现在春季大量蒸发阶段或秋季缓慢蒸发阶段；就垂直变化而言，黄河流域不同旱作类型区土壤水分垂直变化的趋势均表现为上层变化幅度较下层大。

Bear markets seem to be divided into three phases: the first being the abandonment of hopes upon which the final uprush of the preceding bull market was predicted; the second, the reflection of decreased earnings power and reduction of dividends, and the third representing distressed liquidation of securities which must be sold to meet living expenses.

大概意思为熊市的三个阶段：第一阶段，打破前期对牛市顶峰预测的希望；第二阶段，"下跌"显示在公司业绩上，具体表现为盈利能力和分红的减小。第三阶段，表现为社会赖以支撑资金周转的媒介的流通能力、借贷能力渐弱。

The article analyzed progress of volution of human civilization and its future trends,and human survival modes (human living mode,human production mode and human organization mode) in primitive civilization,agricultural civilization and industrial civilization,and proposed the view that the current human is in a transition period from industrial civilization to a new environmental civilization.

在此基础上分析了人类文明演变的历程和今后的走向，剖析了人类的生存方式(人类的生活方式、人类的生产方式和人群的组织方式)在原始文明阶段、农业文明阶段、工业文明阶段的不同样式，提出了当今人类正处于由工业文明时代向新的环境文明时代转折的过渡阶段的论断。

Development of the west female doctrine has experienced three theory stages: The main target of first stages is pursuing equal political right with male. The tone of second stage is remove the difference of amphiprotic. At the third stage, attach importance to the examination to female authority and development, and exceed the difference of men and women. Especially, take more attention to extremely important problem and the solution of female problem.

西方女性主义的发展经历了三个理论阶段：第一阶段主要与社会自由解放的革命运动一起，以追求与男性平等的政治权利为主要目标；第二阶段其基调是要消除两性差别：第三阶段注重对作为人的女性权力和发展的普遍性的考察，超越男女性属差别，注重关于女性更加重大的紧要问题和解决方法。

Where the policy relates to a voyage which is performed in d ifferent stages, during which the ship requires different kinds of or further prep aration or equipment, there is an implied warranty that at the commencement of each sta ge the ship is seaworthy in respect of such preparation or equipment for the pur poses of that stage.

3在保险单有关的航次分不同阶段履行之场合，在各个阶段中，船舶需要不同种类的装备或进一步准备，有一项默示保证，在每一阶段开始时，为各该阶段之目的，船舶就有关此种准备或装备是适航的。

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。
