In switching tactics from proletarian dictatorship to a union of all groups, Mao was certainly closer to the February Revolution in Russia or even in some respects to the French Revolution or a Cromwellian peasant war than to the October Revolution.

毛泽东把无产阶级专政的策略改为联合各集团的策略，与其说这像俄国十月革命，不如说更接近于俄国二月革命，甚至可以说在某些方面更接近于法国大革命和克伦威尔的农民战争。

An example of dynamic simulation of a higher-order cumulant based speech analysis and synthesis system is realized in SIMULINK by -function.

该系统解码后恢复的语音性能更接近于原始语音，所估计的激励信号更接近于白噪声。

The results of lattice beam internal force calculated method based on double parameter groundsill model are more approach the experiment measured values because of consideration of the pass of shearing force in soil, and its calculated workloads are similar with the method of winkler elastic foundation. Besides, the thesis also discusses the moment of torque affected results on node stress situation and the correction of stress value at the bottom of cross node of lattice beam. Due to the repeat calculation of node area during internal force calculation, the stress value of the bottom of beam is lower, this may lead the calculated value unsafe, but the corrected stress value will more approach to practical situation.

对格构梁的内力计算提出基于双参数地基模型的格构梁内力计算方法，其计算结果表明，双参数地基模型上的格构梁内力由于考虑土中剪力的传递更加接近于试验实测值，其计算工作量与winkler弹性地基梁法相当，此外，文中还探讨了扭矩作用对格构梁节点受力情况的影响结果以及格构梁交叉节点底部的应力值的修正，由于内力计算过程中节点处的面积被重复计算，使得梁底应力偏小，可能导致计算结果的偏于不安全，修正后的应力值更接近于实际情况。

If there are two such numbers, then the one that is closest to positive infinity is returned.

如果有两个同样接近的整数，则返回最接近于正无穷的那个。

Thus, along with that the geometry of a particle is closer to a plane gradually the freezing temperature will approach to the temperature of water nucleation on a plane until two temperatures join up.

于是， 随着粒子的几何形态接近于平面，结冰温度也将接近于水分在平面上的结冰行为，直到二者相衔接。

As for sulfur isotopic composition, the general feature of two types deposits is a single peak distribution. All δ〓s values of the ores are near zero. The difference of different deposits lies in that the δ〓s values (1. 8-5. 2‰) of LDT are of small positive value and are similar to that of the metamorphic rocks and dioritic porphyrites in the region while the δ〓s values of SDT are always near zero. Features above suggest that two types of deposits have closely genetic relationship to metamorphic and magmatic rocks.

硫同位素组成上，两类金矿床共同的特征是均具有明显的单峰塔式效应，且δ〓S值均位于0值附近不大的变化范围内；不同的是，近程式金矿的δ〓S平均值均接近于0，与该类金矿具密切成因联系的岩体的δ〓S值也接近于0值，而远程式金矿的δ〓S平均值均为小的正值，变化范围为1.8～5.2‰，区内太古代变质岩及矿区内闪长玢岩脉的全岩δ〓S值位于这一区间内，反映了远程式金矿床其成矿物质不仅来源于重熔岩浆，同时还可能部分来源于变质岩围岩。

None of the four models could work well in the scenario 2, under explored stock, however they got accurate results in scenario 1, regulated stock. The Schnute model work well in full explored stocks such as scenario 1, 3, 4 and 5, especially in low biomass stocks such as scenario 3, but not suitable to the under explored stocks such as scenario 2. The W-H model generally performed well in all kind of scenarios especially in scenario 1, 4, and 5. In the swordfish, xiphias gladius, fishery, estimation of W-H model and D-Fox model produced MSY about 14000 ton, very near the result of Prager in 1996.The author tentatively explored the suitable fishing condition for the models to stock assessment.

四种剩余产量模型在充分捕捞且管理良好的渔业1中评估效果较好而在捕捞不足的渔业2中效果较差；Schnute模型在充分捕捞的渔业如渔业1、3、4、5、尤其是在低生物量的渔业3中评估效果较好，但不适合评估未充分捕捞的渔业，如渔业2；Walters-Hilborn模型适用于各种渔业，尤其是渔业1、4、5；在过度捕捞渔业中如渔业3、4，模型对参数q的估计较其它参数接近真值；在北大西洋箭鱼渔业的评估中，W-H模型和D-Fox模型对MSY的估计约为14000吨，接近于Prager(1996)的结果。

Compared to the flat culture, cells in 3-D culture more closely mirror what happens in living organisms in morphology, cell alinements, polarization, microenviroments, gene expression pattern and other biological characters. Therefore,3-D culture is useful to investigate the molecular mechanism of nasopharyngeal carcinogenesis.

因与传统的二维培养相比，细胞在三维培养中的形态、排列方式、极性及微环境更接近于体内状态，其基因表达和生物学行为也更接近于体内状态，因而建立能反映鼻咽癌发病不同时期的体外三维培养模型对于鼻咽癌的发病机制研究具有重要价值。

The temperature gradient is larger in case ofussual half-zone model which has a uniform temperature distribution on the hot rod,andmodified half-zone model which has a non-uniform temperature distribution in the hotrod and negative radial temperature gradient near the axis of the hot rod.

模拟半浮区模型提出选择热传导系数与试验液体相当的材料作为热端棒材，使得热端内侧的轴向温度梯度接近于零。模拟半浮区模型的温度分布更接近于全浮区温度分布的一半。对于改型半浮区模型，选择热传导系数高于试验液体值一个数量级的材料作为热端棒材，使得热端温度分布不均匀，并且热端内侧温度高于外侧温度。
