The results showed: for the toxicity of two kinds of pollutants, the Cd(superscript 2+) is more poisonous that the Pd(superscript 2+). For the sensitivity to the pollutants, the P. caudatum, C cathayensi and D. japonica increase evidently in turn. The statistical analyses indicated that the single and combined toxicity effects both increase with the exposed time extended, especially for the combined toxicity (P.05), showing a marked time-effect relation. As for the single effect, ii increase prominently with Pb(superscript 2+) and Cd(superscript 2+) concentrations (P.05); But in the case of binary effect, the results showed obviously a time-effect (P.01) as well as a concentraction-effect relations.

结果表明：在同等条件下，Cd(上标 2+)对三者的致毒效应都明显强于Pb(上标 2+)；3种动物中，草履虫最敏感，而圆田螺耐受能力最强；随单一毒物浓度的增大以及暴露时间的延长，两者的致毒效应都显著增大，表现出明显的浓度－效应和时间－效应关系；二者复合作用时，对3种动物的致毒效应主要表现为与二组分的浓度比例有关。

Polyethylene wax the ink percentage by weight of which is 0.6% to 1.2% and ceresin wax the ink percentage by weight of which is 3% to 5% are added to gravure ink in the time of gravure printing.

本发明的耐蹭脏的能力好；一方面标贴图纹具有雕刻凹印特有的立体感与层次感，是一般的印刷方式难以仿制的；另一方面易碎纸在外力作用下易碎的性能使得标贴无法整张被揭起和重复使用，防伪效果好。

The result indicated, In the MS culture medium, and the damagement increased with Pb(superscript 2+) concentrition, when Pb(superscript 2+) concentration was up to 1000μmol/L, the callus was geatly damaged and its character is small, hard, skin drying; Organic acid of suitable concentration was able to improve the induction and growth of rice callus under the Pb(superscript 2+) stress, i.e. ascorbic acid, critic acid and oxalic acid The effect was the best which added 750 mol/L citric acid in MS culture medium, the callus was fresh, light yellow, loose, the surface moist. and survival was as higher as controlled treatment.

而添加不同有机酸（抗坏血酸、柠檬酸和草酸）均可明显改善Pb(上标 2+)胁迫下愈伤组织的生长，尤以750μmol/L柠檬酸对Pb(上标 2+)毒害的缓解效果最佳，其愈伤组织块颜色浅黄，表面湿润，愈伤组织成活率高，与对照愈伤组形态较接近。

Results indicate: after compelling exposal, with the increase of low lighting level, the three reaction time curves have a same decline tendency, and there is an effective inflexion at 50 lx lighting level.

结果表明：在三种曝光强度下，随着视标照度水平的提高，受试者判别反应时曲线都呈先急后缓的下降趋势，并在视标照度为50 lx时出现一有效拐点。

A new goniometric methods is proposed in this paper according to this dynamic target.

本文就是根据此靶标的设计将靶标模拟出的不同运动状态下的室内运动目标作为真值，提出一种基于光学动态靶标检测光电经纬仪测角精度的方法。

Under these conditions, the yield of cyclohexanone glycol ketal could be reach 90.4%, indicating that rare earth composite solid superacid SO4(superscript 2-)/ZrO2(superscript 3+) is a good catalyst for the synthesis of cyclohexanone glycol ketal.

在此条件下，缩酮收率可达90.4%，说明稀土复合固体超强酸SO4(上标 2-)/ZrO2/Gd(上标 3+)是一种合成环己酮乙二醇缩酮的优良催化剂。

文中以高速贴标机为应用对象，实现了知识表达和知识建模，开发了网络环境下虚拟高速贴标机的设计系统。

Under initial pH value of 1.6, Fe(superscript 3+) concentration of 8.58 g/L and temperature of 70℃, after eight hours stirring leaching with the Fe(superscript 3+) solution made by biochemical oxidation, the leaching rate of marmatite was above 90% when pulp density was 3%, the leaching rate marmatite was up to 95.18% when pulp density was 1%.

菌生Fe(上标 3+)浸矿剂对铁闪锌矿的浸出表明，在初始pH=1.5、Fe(上标 3+)浓度为8g/L、温度为70℃的条件下浸出8h，当矿浆浓度小于3%时，浸出率可达90%以上，其中矿装浓度为1%时的浸出率高达95.18%。

Methods With AT89C51 single-chip as hardware and programmed by C language, the instrument applied, the optometer adopted LCD and international standard optotype. The optotype had 14 lines of object-finders, and only one line of random characters was displayed on the screen every time.

硬件采用AT89C51型单片机，软件采用C语言编程，显示部分采用液晶显示，以国际标准视力表&E&字为视标，视标共14行，每屏显示1行，随机显示字符，视力检查距离为3m，全部程序在单片机控制下完成。
