查询词典 difference

Here are the results: there are no clear difference in the length and width of leaf epidermis stomatal apparatus, stoma density and vascular bundle area in 1st internode below the ear between cold and warm type wheat. The vascular bundle area in 2nd internode below the ear of cold type wheat is obvious smaller than warm type wheat's. There are clear difference in the vascular bundle number in unit transverse area of 1st internode and 2nd internode below the ear and the rate of the total area of vascular bundle and the transverse area of wheat stem between cold and warm type wheat.

研究表明，冷、暖型小麦叶表皮气孔器的长度和宽度、气孔密度、穗下节间中维管束面积均无显著差异；冷型小麦倒二节间中维管束面积明显小于暖型小麦；冷、暖型小麦穗下节间、倒二节间单位横截面积中维管束数目、维管束总面积占茎横截面积的百分率均有显著差异。

The results show that amplitude of defect signal is adversely affected by lift-off variations,but phase difference between defect signal and lift-off loci is almost unchangeable.After analyzing the characteristics of the phase difference with the chang of frequency,a conclusion that defect signal is approximately vertical to lift-off noise at a well-selected frequency is obtained.

结果表明提离增加会显著降低缺陷信号的幅值，但并不影响缺陷信号和提离轨迹之间的相位差，通过分析相位差随检测频率的变化规律发现：存在一个合适的频率可使缺陷信号和提离干扰之间出现90°的相位差。

The analysis shows that with given grid size higher accurate difference scheme can give higher resolutions with wider range of scales, or with given accuracy large grid size can be used for the higher accurate difference scheme. The second part is the numerical simulation of two-dimensional axisymmetric jet. The simulation results show the structure in the near field and the initial transition. In the near field, Kelvin-Helmholtz instability leads to the formation of vortex ring, and nonlinear growth leads to the merging of vortex ring. This is the main instability form. Under the assumption of axisymmetry and two-dimensional computing conditions, the results are applicable only in the near field.

第二部分采用高精度的差分格式对二维轴对称射流进行了数值模拟，模拟结果显示了射流流场结构和涡结构的发展过程，在射流流场近区，K-H失稳导致涡环的产生以及非线性效应的增长导致涡环的对并是射流失稳的主要形式；分析指出在轴对称假设下的射流数值模拟只适用于射流近区的分析。

The difference of the characteristics of HHQ monolayer is dependent on the difference of radii,nuclear charges and the structures of valence shell of metal ions.

金属离子的半径、电荷及核外价电子层结构不同是影响HHQLang－muir单分子层膜性能的本质原因。

Xinjiang town civilian between the difference of income and countrywide level and town dweller the difference of income.

新疆城镇民的收入与全国水平的差距及城镇居民之间收入的差距。

Aim to set out from the expression of difference of town dweller income, discussed the matter that difference produces, offerred the measure that solve.

旨在从城镇居民收入差异的表现出发，探讨了差异产生的原因，并提出了解决的措施。

By the comparison of calculation result with the tests result, it was concluded that the method to calculate the year temperature difference and day temperature difference from weather data was feasible.

小砌块砌体结构常见的荷载类型对顶层相对位移影响很小，在位移控制的正常使用极限状态方程中仅需要考虑温度作用的影响。

Another important conclusion is that the shape difference between the PMT outputs is the main influence factor of the TOF detector's time resolution, and it is necessary to consider the influence of the shape difference while performing time correction.

通过分析还可以看到，信号的形状差异带来的时间误差对TOF探测器的本征分辨率有着重要的影响。因此，如果要获得更高的时间测量精度，在进行时间修正的时候必须考虑信号形状差异的影响。

The identification of tea plant resistance to tea brown blight The resistance of 13 tea plant cultivars to tea brown blight had the difference or remarkable difference. In general, the resistance of big leaf cultivars was relatively weaker, the resistance of middle leaf cultivars was relatively stronger.

茶树品种抗云纹叶枯病的鉴定 13 个茶树品种对茶云纹叶枯病的抗性存在显著差异，一般大叶种材料的抗性较弱，中叶种材料的抗性较强。

The experimental results show that the estimated strength of cylindrical specimens and core specimens taken from plate-like specimens under the condition of saturated surface-dry were good and the difference between the estimated strength and the measured strength is within 10%. For the plate-like specimens used in this study, measured the surface P-wave and internal P-wave, and investigate the difference between surface P-wave and internal P-wave velocities. Firstly, the internal P-wave velocity was recovered to the saturated surface-dry condition.
