In order to eliminate disturbance of the feed stock, a feedforward controller was designed in the system.The designed soft sensor and control strategy were used in one selected olefin plant and the results were demonstrated and discussed in this paper.

丙烯浓度智能控制系统对塔釜丙烯指标进行实时控制，提高了塔釜丙烯浓度的控制平稳度，解决了塔釜丙烯浓度超标问题。

Result When the concentration of rotifer was 250 ind/ml, the effective concentration of strengthener was 3×10^6-3×10^8 ind/ml and the best concentration was 3×10^7 ind/ml.

结果］轮虫浓度为250ind/ml时，强化剂有效浓度为3×10^6-3×10^8ind/ml，最佳浓度为3×10^7ind/ml。

It was observed that low salt con-centration had a stimulating effect on germination.In general,the percentage of germination declined withsalt concentration increasing.The response of stylo seeds to salt stress varied with a changing concentra-tion and the type of salt used in individual treatment.

结果表明，低盐浓度对部分柱花草种子萌发有促进作用；随着盐处理浓度增高，发芽率一般呈下降趋势，但也有例外；不同浓度的盐胁迫下柱花草种子的适应情况不同，同一柱花草种子在萌发时对不同盐的适应情况也不同。

As for chlorophyll, rice and potato have the highest chlorophyll concentration, the value is 25%～35%; the next are corn and sugar cane with value of 20%～30%, and chlorophyll concentration of chestnut is 20%～25%.

对于叶绿素，水稻、马铃薯的叶绿素浓度最高，为25%～35%，其次为玉米、甘蔗，叶绿素浓度为20%～30%，而栗树的叶绿素浓度为20%～25%。

Results:The better linear range of chloroform and tetrachloride ...

结果：氯仿和四氯化碳浓度在0~80μg/L范围内，线性较好，相关系数分别为0.9993和0.9991；氯仿的最低检出浓度为0.05μg/L，四氯化碳的最低检出浓度为0.03μg/L，跟国标方法相比降低了两个数量级，灵敏度大大提高。

In addition, thermostability of high protein concentration was also researched.

从内源荧光的检测结果也可以看出，在相同的变性剂浓度下，突变体的活力损失及三级结构的变化都要快于野生型；在不同的变性剂浓度下，使突变体发生活力损失及三级结构的变化的浓度总是要低于野生型。

The sources and characters of thoron 220 Rn in the buildings, the pattern of indoor thoron 220 Rn's concentration and the assessment of hazard which it brings to human being are discussed,and the method of measurement of indoor thoron's concentration is expounded and the measure for reducing thoron 220 Rn in the buildings is also pointed out.

综述了建筑物内钍射气220 Rn 的来源和性质，讨论了建筑物内220 Rn 浓度的模型及其对人类的危害风险评估，探讨了建筑物内220 Rn 浓度的测量方法，提出了降低建筑物内220 Rn 浓度的措施。

After Cryopreservation of embryo and larvae of pacific oyster Crassostrea gigas, the results indicate the survival rate of trochophore larvae is 61.1% and significantly better than that of other stage embryo or larvae(P.05).The effect of high sucrose density is better than that of low sucrose density with the same DMSO density.

对太平洋牡蛎的胚胎和幼虫的超低温冷冻保存发现，担轮幼虫的解冻复活率最高，达61.1％(3.0M DMSO)，显著高于其他发育阶段幼虫的保存结果(P＜O.05)；牡蛎担轮幼虫的保存结果显示，在相同DMSO浓度条件下，高蔗糖浓度组保存效果好于低蔗糖浓度组，但差异不显著(P＞0.05)。

The producdon concentration is obtained by analytical method which had no truncation error and rational concentration.

由于用解析法求解浓度不存在任何截断误差，且浓度的解总是位于合理解的范围内，故采用解析法求解产出液浓度。

Compared to the other carbon and nitrogen sources studied, sucrose and malt extract were found to be the suitable carbon/nitrogen sources. The decolorization efficiency of Cerrena unicolor Y5002 to orange G was similar at different orange G concentration below 500mg/L; however, alizarin red inhibited the decolorization reaction at the concentration of 400mg/L or above 400mg/L.

对一色齿毛菌Cerrena unicolor Y5002的液体培养脱色条件进行了研究，其最适碳源和氮源分别为蔗糖和麦芽浸粉；在不同橙黄G浓度下均获得较高的脱色率，因此浓度为500mg/L的橙黄G未对该菌的脱色能力产生抑制作用，而浓度为400mg/L茜素红则对其脱色作用产生明显抑制。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
