The results showed that for the two peony cultivars, before flowering and during flowering period the day rate changes of net photosynthesis rate were up to the maximum at 12:00, and there were no photosynthesis "sleep at noon" phenomenon, therefore, during the two period, the curves of net Pn of the peony leaves only have one peak.

However, the transformation rate from dominant stem to overtopped stem and from overtopped stem to dominant stem were the lowest. The interconversion of classified stem would increase as the stand density and the rate of L. gmelinii was going up. The altitude that classified stem mainly concentrated was less than 1000m, slope was less than 25°, aspect was south slope, position was at middle and lower, soil depth less than 17cm. The rate of no interconversion was 66.7% among overtopped stem. It should cut the overtopped stem as intermediate cutting.

优势木转被压木和被压木转优势木的转换率最低；随着林分密度和林分中落叶松比例增加，分级木相互转换数也增多；分级木转换现象主要集中在海拔＜1000m、坡度＜25°、坡向为阳坡、坡位为中下、土壤厚度＞17cm的林分中；被压木中，无转换的占66.7%，抚育采伐时应考虑伐除这些被压木。

The results show that when 40%,60%and 80%of the water field capacity in root systems deep range (about 40 cm deep soil) is taken as the amount of water supply the period of growth, the economic yield and benefit isn′t increased at the same rate. In order to increase the product at a great rate, the amount of water supply must be over 60%.

试验结果表明，在辣椒根系生长范围内，分别以田间最大持水量的40％、60％和80％做为整个生长期的补充水量，产量和产值并未随补充水量的增加而同幅度提高，要使产量大幅度提高，补充水量必须在根系生长范围内田间最大持水量的60％以上。

When mixed into the same carbon fiber quantity is 1.0%, differ age material's AC impedance chart is discrepancy very much, along with to hydrate age's add, C-S-H gel isa great deal of form, the solution resistance at the concrete is gradually aggrandizement, the carbon fibre of here qua transmit electricity quality disperse would leading effect of conductance, along with the add of exterior load, the transmit electricity quality of concrete is almost nothing change, till breakage, resistance change rate tempestuousness add, and that the resistance change rate along with inside stress linearity add of corbon fibre concrete in elasticity phase, when near peak value load, resistance rate just gradually add, indicate the test sample would be about to breakage.

当碳纤维体积掺量同为1.0%时，不同龄期材料的交流阻抗谱相差很大，随着水化龄期的增长，C-S-H凝胶大量形成，水泥基材料中的溶液电阻逐渐增大，此时作为导电性分散相的碳纤维将起电导的主导作用。随着外部荷载的增加，基准水泥基材料的导电性几乎无变化，直到破坏时，电阻变化率剧烈增大，而碳纤维水泥基材料在弹性阶段其电阻变化率随内部应力线性增加，当接近峰值荷载时，电阻率才逐渐增大，预示试件即将破坏。

Testing directly the hypothesis that the intercept is the risk-free rate when the weekly Treasury bill rate is used for this purpose, we accept this hypothesis at the 5% level for the groups of 30 and 60 stocks but reject it for groups of 90 stocks at the 10% level .

直接拦截试验是假设无风险利率当务周刊法案速度的快慢为此我们接受这个假说在5%左右的股票和60组30批90但拒绝为股票10%的水平。

This paper is based on "Trilemma" which is induced from MF model. In order to overcome MF models inherent defects, this paper constructs a static model headed by government on choice of optimum exchange rate regime. Through the analysis of the model we can see that the choice of exchange rate regime is a dynamic process should be decided in real situation. No single exchange rate regime is right for all countries or at all time. Under certain condition intermediate regime may be the optimum one, but the possibility will decrease with the increase of international capital flow.

本文从蒙代尔——弗莱明模型精炼出的"三元悖论"出发，为了克服其内在的缺陷，构建了一个政府主导的静态最优汇率制度选择模型，模型分析表明：汇率制度选择是一个动态的相机决策过程，没有哪一种汇率制度对所有国家或某一国的所有时期都适合；在一定条件下，中间汇率制度可能是最优汇率制度，但是其可选择的区间随着资本流动程度的加大而缩小，最终最优汇率制度将内生的向两极分化。

The development speed of gynogenetic embryos was later than that of the control group, and aneuploids were found in this study. The obvious improved survival of trochophore larvae with a peak at 40s UV exposure suggested the presence of a Hertwig effect in the gynogenesis of A. pectinata. When sperms were irradiated for 40s, the cleavage rate was relatively high (51.2%), the developmental rate of D-larvae became zero, and the rate of haploid reached the highest (36.8%).

经紫外线照射的精子受精后所产生的单倍体胚胎发育速度慢于正常受精所产生的二倍体胚胎，各照射组均出现非整倍体。40s照射组中卵裂率达到51.2%，D型幼虫发生率为0，单倍体率最高，达到36.8%，出现"Hertwig效应"。

After salinity changing, it was about at the 24h of the experiment that the peak level of oxygen consumption rate was saw, however the highest ammonion exretion rate was seen only at 9~15h after the experiment began.

在突变后24h左右各突变组大菱鲆幼鱼耗氧率出现高峰值，48h后恢复到突变前的水平，此时各实验组大菱鲆的耗氧率没有显著的差异性(P＞0.05)。

Results of nitrogen balan ce calculation indicated that nitrogen surplus Was primarily existed with Nmin at low nitrogen application rate,while Was primarily apparent loss at high nitrogen application rate treatments.

氮素平衡计算的结果表明，低施氮量时，氮素盈余以残留Nmin为主，高量施氮则以表观损失为主。

After the oxidative polymerization of DMP,styrene was in-situ polymerized under the initiation of dibenzoyl peroxide and dicumyl peroxide,finally thermodynamically compatible PPO/PS alloy was prepared.When styrene content was 50 wt%,for the synthesized PPO/PS alloy the yield and the weight-average molecular weight were determined to be 95%and 1.7×10~5 for PPO,93%and 2.0×10~5 for PS,respectively.The influence of the concentration of DMP and catalyst,molar ratio of N/Cu, oxygen partial pressure,NaOH concentration and temperature on the initial polymerization rate(R_0) of DMP was studied.It was found that the initial polymerization rate of DMP increased with the concentration of DMP and catalyst. The initial polymerization rate increased with the molar ratio of N/Cu at first and then decreased.

通过测定DMP氧化聚合过程中氧气吸收量随时间的变化，研究了DMP和催化剂浓度、N/Cu摩尔比、氧气分压、氢氧化钠浓度及温度对水介质中DMP氧化聚合初始速率的影响，发现DMP氧化聚合初始速率与氧气分压的0.1次方成正比；DMP氧化聚合初始速率随DMP和催化剂浓度及温度的增加而增加；随氢氧化钠浓度和N/Cu摩尔比的增加DMP氧化聚合初始速率先增加后降低。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
