The inhibitory rate of DMHMP was lower than DCD when the same dosage added but higher than DCD while the added dosage of DMHMP was duplation of DCD.

当添加DMHMP的量与DCD相等时,其硝化抑制作用不如DCD,而当其添加量为DCD的2倍时,其硝化抑制效果明显优于DCD。

The relationship between elastic strain energy and the reduction coefficient can be used as criteria in slope stability analysis using strength reduction method.

研究结果表明:采用强度折减法,当边坡处于稳定状态时,折减系数增大引起边坡变形增大,导致边坡体弹性应变能随之增大;但是,边坡岩土体能够承受的弹性应变能是有极限的,当折减系数增大到某一值时,边坡体的弹性应变能达到极限,再增大折减系数将导致边坡失稳破坏;边坡体弹性应变能与折减系数服从指数关系;利用弹性应变能与折减系数关系曲线得到的边坡安全系数与采用其他经典的方法所得边坡安全系数基本一致,弹性应变能随折减系数变化而变化的规律可以作为边坡稳定性强度折减法分析的失稳判据。

He proved that:if the total moving times of mesh M is a finite number and independent ofΔt andh.the L2-norm error estimate is optimal;if Mh is independent ofΔt and bounded,energy norm error estimate is optimal.

并证明了当网格变动次数M是不依赖于Δt和h的有限数时,近似解与真解的L2误差估计是最优的;当Mh不依赖于Δt且有界时,能量模误差估计最优。

Morphological observation showed that exposure of≥0.625 mmol/L Na2SO3 could decrease cell numbers significantly and living cells seemed narrower and longer than the usual way with fewer evection. But lower concentrations of Na2SO3 (≤0.156 mmol/L) did not change cell numbers and cell morphology.

形态学观察发现,当接触亚硫酸钠浓度≥0.625mml/L时,细胞数量明显降低,细胞比较细长,突起较少;当亚硫酸钠浓度簇0.156mmol/L时,细胞数量和形态基本无变化。

Therefore the dispersion curves obtained in the field are primarily consisted of the first mode. For a heterogeneous elastic solid consisting of three homogeneous layers whose interlayer has low velocity, the phase velocity V〓 of the first mode will also close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, but V〓 of the first mode will close up to the shear wave velocity of the interlayer when f→∞, and there is a cut-off frequency at high frequency region for the first mode and V〓 close up to the compressional velocity of interlayer when interlayer is liquid.

当三层固体介质中存在软夹层时,若f→OHz,则其基阶模式的相速度V〓→V〓(V〓为最底层介质的瑞利波速度);若f→∞,其基阶模式V〓→V〓(V〓为中间层介质的横波速度);若三层介质中存在液体夹层,当f→OHz时,基阶模式V〓→V〓,而基阶模式在高频段存在一个截止频率,截止频率处的瑞利波速度V〓→V〓;由此可判定,野外实测的相速度频散曲线不仅有基阶导波模式,同时还应有高阶导波模式波的存在,接收信号中存在模式间的跳跃,因此频散曲线会产生"之"字形现象。

Those figures indicate that when delay is very small, the stability of steady states doesn't change and chaos still exist. As delay increases, the stability of steady states is changed. When delay is near some critical value, a family of periodic solutions bifurcate from the steady state.

这些系统的相图显示了当时滞为零或者时滞很小时,平衡点的稳定性没有发生变化,于是轨道的混沌震荡也没有发生改变,而当时滞逐渐增大时,系统的混沌特性会发生变化,在τ取某些值时,混沌震荡会演变为一个稳定周期轨道。

The results show: when the eyes gaze at the 0° field of view, the lens can provide an 1-arcmin resolution. And Turning the eye and focusing on the 14° field of view, the lens can provide an 1.1-arcmin resolution.

MTF的评价结果显示:当眼睛注视0°视场时,系统达到1.1 arc minute的分辨率;当转动眼睛注视+14°视场时,系统达到1.1 arc minute的分辨率。

55 Now, initially the flourescent tube isnot lit. There's no power control going on. But onceit gets these high voltages, the lamp is what is calledstruck. That's when the arcing occurs between the ends

开始时,荧光灯管没有点亮,系统也没有电量控制,当给荧光灯管加上高的电压,就是所说的电击打,当在灯管两端之间形成电弧时,灯管中的气体被充电,玻璃管内基本上就得到了光亮。

From the special viewpoint of information and belief, our analysis finds that through refusing free information the current self can restrain future selves' ill tendency when the external information are static stock. This conclusion can be supported by finite or infinite horizon model as well. When external information are dynamic flow, current self's controlling instrument is forestallment, sometimes he would invest even under negative net present value. Selective memory can also serve as a controlling instrument, current self selectively convey information to future selves.

本文选取了信息与信念这一独特视角,深入探讨现期自我的控制手段,研究发现:当信息为静态的存量时,现期自我可通过拒绝外生信息克制远期自我的不良倾向,该结论在有限期或无限期模型中均成立;当信息为动态流量时,时间不一致矛盾将侵蚀等待的期权价值,现期自我会以抢先行动的方式拒绝进一步信息,甚至采取NPV为负的行动;现期自我也可通过选择性记忆向远期自我传递信息,这就是信息传递阶段的控制手段。

We are never so defenseless against suffering as when we love,never so forlornly unhappy as when we have lost our love object or its love.

当我们相爱时,我们从没有如此的脆弱;当我们失去爱或者爱人时,又是从没如此的孤独与无助。
