The obstacle (the altitude of 900 mm) process for both sides of a planetary gear train was analyzed in ADAMAS. It is proved that the physical dimension of the planetary gear train, bodywork center position and attachment coefficient are the key effect factors. The driven moment, velocity and normal pressure sharply increased as each wheel surmounting obstacles, but they were moderate after the front wheel came over the obstacles. Another weaker pulse occurred when the rear wheel began climbing, and then the parameters reached a plateau.

行星轮系的结构尺寸、车体质心位置及附着系数对越障高度影响较大；各轮系越障时出现驱动力矩、速度和正压力急增的现象，前轮系的前轮越上障碍后，各参数值趋于平稳，后轮越障时又出现瞬时脉动，但脉动较小，后轮系也有相同的变化趋势，各轮的阻力矩和输出功率与正压力变化趋势相同。

Finally, twelve monthly binning secchi depth maps are build by using 1988 MODIS images from 2004 to 2007. The results show annual variation of secchi depth, absorption coefficient, and backscattering coefficient.

最后利用推估结果较佳的波段与关系式，将2004年至2007年共计1988张MODIS影像，叠合成1至12月份计12张台湾海域的沙奇盘深度推估影像，并分析其四年的变化，结果显示台湾海域的沙奇盘深度与吸收系数，以及背向散射系数皆有年的周期性变化。

It is nothing else than impurities prenatally inherent in ore that seriously affect the quality of the latter, which is formed as a result of geological vicissitudes including diastrophic movement, eruption of volcano, sedimentation, glaciation and weathering etc.

对矿石质量最有影响的莫过于其本身所含的杂质。杂质的形成是地质变化的结果。比如象地壳运动，火山喷发，矿石沉淀，冰川和风化等所造成的地质变化。

The experimental results indicate that the camera data have strong correlation with the physical measurement and also fit well with visual data except for a slight slope shift existing in lightness due to a divinable psychophysical magnitude variation for spatial-dependent color samples.

实验结果表明，相机数据与光谱辐射计量结果之间具有很强的相关性；与视觉评价的比较，除了与珠光瓶体类似具有空间变化的颜色样品因其可预测心理感知尺度的变化而使相机数据的明度变化率略有偏移外，相机结果与视觉数据也有效相符。

After radiation, dog brain existed micro-changes injury. DWI is a most sensitive functional imaging technique in detecting hydrone diffusion capability changes. It can discover and quantitatively analyze the micro-changes preceding anatomy imageology by measuring the irradiated tissue ADC value.

核辐射损伤犬脑在解剖影像学尚未出现异常改变之前已存在微观的病理变化；DWI是一种极其敏感的探测水分子弥散能力变化的功能性成像技术，能够先于解剖影像学发现核辐射损伤犬脑的微观病理改变并通过测量辐射损伤组织的ADC值加以定量分析，有重要的临床应用价值。

The findings: with the apparent dominant frequency of the Ricker wavelet rising, the detection SNR will get worse gradually, it is obvious that the variety of the SNR is slower during the portion of high frequency than during the portion of low frequency; in the usual range of seismic prospecting frequency, the SNR of the chaotic oscillator detection system could partially make up the amplitude attenuation aroused by the transmit of the seismic wave; the results could provide help for detecting the event constituted by aberrant wavelets.

本文以Ricker子波模拟地震子波，研究Ricker子波视主频变化的相应检测效果。研究结果：随着Ricker子波视主频的升高，检测SNR逐渐变差，在高频部分SNR的变化明显比低频部分缓慢；在通常地震勘探频率范围内，混沌振子系统检测SNR有可能部分补偿由于地震波传播引起的幅度降低；为检测由畸变子波构成的同相轴提供一定的可能。

The results showed that glucose and fructose are primary soluble sugars from night to 10: 00 a.m. in mature leaves, but during 13: 00 - 16: 00 p.m., stachyose becomes the most abundant oligosaccharide, this diurnal change is mostly due to the tempestuous fluctuation of stachyose concentration in mature leaves. During photoassimilate transportation, the p rimary soluble sugar in phloem sap is stachyose. When transportation is finished, sucrose becomes the main sugar in phloem sap. Cucumber leavesmay store photoassimilate in the forms of starch, glucose, fructose, stachyose and sucrose at night. The concentrations of glucose, fructose and stachyose in phloem sap are much lower than in leaves at that time. There may be some unique mechanisms modulating source-sink translocation by which soluble sugars in leaveswere prevented from loading into the phloem further during night.

结果表明夜间至上午10： 00，葡萄糖和果糖是叶片中主要的可溶性糖，而下午13： 00至16： 00，水苏糖成为成熟叶片中含量最高的可溶性糖，这种变化主要由叶片中水苏糖含量剧烈的昼夜变化引起；当黄瓜同化物从源叶向外运输时，韧皮部汁液中的可溶性糖以水苏糖为主，运输完毕后则以蔗糖为主；黄瓜成熟叶片在夜间以淀粉、葡萄糖、果糖、水苏糖、蔗糖等各种形式贮藏尚未运出的同化物，而此时韧皮部汁液中葡萄糖、果糖、水苏糖的含量极低，可能有特定的源库调节机制阻止叶片中的可溶性糖在夜间进一步向韧皮部中装载。

The results showed that elevated CO2 increased the R/S ratio and the dry mass of both coarse and fine roots, indicating that the seedlings under elevated CO2 allocated more biomass to their belowground part. Compared with control, elevated CO2 increased the contents of reducing sugar, sucrose, and total soluble sugar in coarse roots significantly, but had less effect on those in fine roots. Elevated CO2 increased the contents of starch and total non-structural carbohydrate both in coarse roots and in fine roots. Under elevated CO2, the carbon content in coarse and fine roots had an unsignificant increasing trend, while the nitrogen content decreased significantly, which resulted in an increase of C/N ratio.

结果表明：CO2浓度升高使红桦幼苗粗根和细根的干质量增加，同时根／冠值显著升高，表明CO2浓度升高使红桦幼苗生物量向根系的分配增加；与对照相比，粗根的还原糖、蔗糖和总可溶性糖含量显著增加，而在细根中没有显著变化；粗根、细根的淀粉和总的非结构性碳水化合物含量显著增加；CO2浓度升高下粗根和细根的碳含量有升高的趋势但未达到显著水平，同时氮含量降低，碳／氮值升高；氮的吸收量在粗根和细根中均无显著变化。
