It is found that topological charge of vortex beam influences the interference pattern, i.e., by compared with the straight interference pattern of plane wave, the interference pattern of vortex beam is shifted in the transverse direction as we look from the top of the interference to the bottom, and the magnitude and direction of shift are related to the topological charge.

详细介绍了涡旋光束的拓扑荷数对干涉条纹分布的影响。发现同平面波的竖直干涉条纹相比较，涡旋光束的干涉条纹，从顶部向底部看去，沿着横向出现移动，并且移动的大小和方向与拓扑荷数的取值有关。

The calculated size of the fetus is compared with the numbers in the table, and the corresponding tabular value for the length of pregnancy in weeks thus found is converted by the subprogram "Conversion" into a decimal number.

胎儿的大小计算比较表中的数字，以及相应的表格价值怀孕的长度在数周内，从而发现转换的子程序"转换"成一个十进制数。

It will consume lots of CPU time and hard disk space of computer in calculating the ultimate torsional moment of a hull girder by using FEM, especially for the complex structure. The ultimate torsional moment of box thin-walled beam is analyzed by using finite element method. The influences of different characteristic parameters on the ultimate torsional strength are extensively studied.

在船体梁扭转极限承载能力的有限元计算中，对於比较大而且形状复杂的结构，需要采用足够多的单元数来模拟其真实的破坏模态，因而会耗费大量的CPU计算时间和硬盘空间，并且往往因为单元数太多而使数值计算变得不现实。

At the same translational energy, the cross-section increases with the rising of the rotational quantum number j, and declines with the rising of the quantum number m. In the last, we find that the reaction rate constant and the cross-section have the similar rule for the quantum numbers j and m.

最后比较各个量子态的速率常数，我们也看出随量子数j的增加，速率常数升高，随量子数m的增加速率常数降低，这些曲线在我们的图中都呈现相似的下降趋势，这和散射截面的规律是吻合的。

Animal's welfare can be feed back from their vocalism. We had some experiments to get 35 days old chicken's vocalization in different environment, including normal environment、 light off environment and people's disturbing environment. On the base of Mel Frequency Cepstral Coefficient, We introduction a new algorithm for feature extraction---Subband Mel Spectrum Centroid. We used support vector machine classification model to evaluate the performance of using different sound parameters.

本文通过研究35日龄海兰褐蛋鸡在正常状态、光照与人为干扰等应激下发声信息的变化特征，提出基于子带梅尔频谱质心的优化特征参数，并通过建立支持向量机模型，比较了采用优化特征参数与梅尔频标倒谱系数及其一阶、二阶导数组成的特征参数（MFCC_39）在识别不同应激中的应用效果。

Time domain algorithm,range-doppler algorithm and wave number domain algorithm are being discussed and compared on this foundation.

在此基础上，分别讨论时域算法、距离——多普勒算法、波数域算法并对其进行了比较，并对波数域算法的并行性做了初步研究。

研究结果如下： 1 对海南典型野生分布的益智群落，测量单丛茎杆数，株高，单丛果穗数，单穗重，单丛果实产量，果实百粒重和果实产量等形态性状，并进行比较分析。

Thirdly, we also examine the effect of these extracts on maize seed germination rate, maize seeding height and fresh weight, and the results show that three extracts are safe to maize at the concentration of 1:20, with a inhibit rate under 4 %.We further identified and purified organic acids, alkaloids hydroxybenzenes and neutral materials from extract and examined their effects on Amaranthus retroflexus L. seeds.

实验结果表明在干样：水为1：50以内，这三种向日葵的叶片提取液对反枝苋种子萌发和幼苗株高、鲜重及出叶数的抑制效果都非常显著；随着提取液浓度的下降抑制作用也呈明显的下降趋势；通过实验数据比较，这三种向日葵叶片提取液对反枝苋种子萌发抑制和对反枝苋幼苗株高、鲜重及出叶数的抑制效果略有差异。

54 cases' RA activity group compared with 20 cases' relief group and 25 cases' control group, then analyzed the index of patient's condition of RA patients' platelet parameter (ESR、CRP、IgG、IgA、IgM、C3、C4、RF), and associativity of clinical symptom such as arthralgia, arthrocele, subdermal induration, violet and dark oral lip, scaly skin, ecchymosis of corpus linguuae, frequency of petechia.

比较RA活动组54例，缓解组20例和正常对照组25例的血小板参数变化，分析54例活动期RA患者血小板参数与病情活动指标(ESR、CRP、IgG、IgA、IgM、C3、C4、RF)及临床症状（关节疼痛数、关节肿胀数、皮下硬结、口唇紫黯、肌肤甲错、舌体瘀斑或瘀点出现率）的相关性。

Through the multiple comparisons, the production, single-potato weight, number of tubers per plant, per unit area of main stem number, plant height, the rate of commodity potato, or diseased plant rate, diseasedness index of the use of small whole potato seeds were better than that of the traditional cuts planting, but analysis of variance revealed that differences between the two was not significant.

多重比较表明，无论是产量、单薯重量、单株块茎数、单位面积主茎数、株高、商品薯率，还是病株率、病指，利用小整薯播种均优于传统的切块播种，但通过方差分析发现，二者之间差异不显著。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。
