This paper discussed the coordinate transformation method of WGS84 coordinate system to 1954-BeiJing Gauss grid coordinate. Introduced transformation model of WGS84 to Beijing 54 and computing method of transformation parameter. According to different model and computing method, computed and compared with the result combine real data. Think that adopt base-line vector quantity ask four parameters model have higher transformation precision.

His system, known grandiosely as a 'large aperture scintillometer', consists of a laser on one side of a field, a telescope on the other, and a lot of clever computing to interpret what the telescope sees. What that computing is trying to measure is how much the laser beam twinkles as it passes across the field.

Kleissl的系统有一个响亮的名字："大眼睛闪烁仪"，它由以下几部分构成：农田某一边放置一个激光器，另一边有一个望远镜，然后通过大量电脑智能分析，以解析望远镜收集得来的数据：激光器发出的激光在穿过农田，到达望远镜之前闪烁的次数。

The computing plots of the solutions from the two methods were inconsistent under the specified boundary-initial conditions, which stirred up the debate of the effectiveness of Maxwell's equations in lossy medium. It is found that the differences between the two numerical curves can be viewed as the Gibbs phenomenon caused by cutting off the high frequency components in computing the infinite integral of the numerical curve of Harmuth's solution.

通过比较两种解析解的数值曲线得出：两者的差异在于求解Harmuth解的数值曲线时，采取无穷积分的高频截断近似产生了吉布斯现象；在计算Harmuth解的数值曲线时不断增大积分上限，其数值曲线的振荡不断向不连续点处收缩，而且衰减加快，因此在求解Harmuth解的数值曲线时，若积分区间取为理想无限大，则可以预见相同计算精度下两种方法的电场解的数值曲线是一致的。

The maximum limit of liability for damages to a passenger is 16,600 computing units (See Article 213 for explanation of computing unit).

对每名旅客的赔偿责任限额为16600计算单位；但是，旅客可以同承运人书面约定高于本项规定的赔偿责任限额。

The methods of computing for similar coefficient were Discriminance of Minimal Difference of Parameters, Discriminance of Limen of Tree Compositive Character and Synthetic Weight Similarity of Parameters. The contribution of all parameters were considering as same for DMDP and DLTC, but it estimate s the similarity between parameters according to the limen for DLTC. DMDP was based on the principal component analysis for wood transverse section micrograph characters and computing the similar coefficient according to the contribution of every parameter.

其中最小差值差数判别法与树种综合特征阈值法是将每个特征参数对木材横切面显微图像特征的贡献率视为一致，只是树种综合特征阈值法是以阈值的大小来判断特征的相似性，而综合加权相似法是建立在对木材横切面显微图像特征参数的主成分分析的基础上，根据每个特征参数的贡献率大小计算相似系数。

In the past, the high frequency resonance technique is usually applied in the envelope detection for a vibration signal with amplitude modulation. When applying the Hilbert transform in the high frequency resonance technique for the envelope detection of vibration signals, the computing burden is very high. On the other hand, when applying the linear least squares analysis method, the computing burden is lower. When applying the envelope detection in the lowest vibration mode, an accelerometer with the low-pass filtering cutoff frequency at 4kHz should be choose.

在过去的研究方法中，振动讯号之振幅调变通常以高频解调分析法应用於包络讯号侦测，而高频解调方法应用希尔伯特转换的包络分析，所需要的计算量是非常的高，若以线性最小平方分析法应用於高频解调分析法中，则所需要的计算量较小，如果以最低模态来估测包络讯号时，可以适当的选取加速规来代替低通滤波器，而加速规的截止频带必须在4kHz左右。
