Today, the two standard frequencies for generation, transmission, and distribution of electric power in the world are 60 Hz (in the United States, Canada, Japan, Brazil) and 50 Hz ( in Europe, the former Soviet republics, South America except Brazil, India, also Japan). The advantage of 60-Hz systems is that generators, motors, and transformers in these systems are generally smaller than 50-hz equipment with the same ratings. The advantage of 50-Hz systems is that transmission lines and transformers have smaller reactances at 50 Hz than at 60 Hz.

今天，60Hz(在美国，加拿大，日本和巴西使用)和50Hz(在欧洲，前苏联，除巴西以外的南美洲，印度以及日本使用)是世界上发电，输电和配电的两个标准频率。60Hz系统的优点在于系统中的发电机，电动机和变压器通常比同等级50Hz系统的设备小。50Hz系统的优点是传输线和变压器的电抗在50Hz时较60Hz时小。

The organic matter decreased in Autumn and reached to a valley in Winter, then it raised to the peak in Summer and Autumn; the total N fluctuated which change range is smaller than 5%; the soil NHt+-N rose firstly, reduced in Autumn and Winter, then rose in Spring; additionally, its peak appeared in Summer and valley in Winter; the soil NCV-N"s change was more complicated than NHU+-N and fluctuated with season whose peak appeared in rain season; the available N"s change tendency was similar to NH4+-N, it decreased in May; the hydrolysable N fluctuated in smaller range, and its content decreased steadily and showed no apparent peak in a year.

有机质含量秋季下降，冬季下降到低谷，随后逐步回升，夏、秋季达到最高水平；全氮的时间动态仅为小幅度的波动，变幅不足5％。铵态氮的变化趋势为：升高—降低—升高，高峰期出现在夏季，低峰期则出现在冬季；硝态氮的时间变化比铵态氮复杂，呈明显的波浪式起伏变化，最高峰出现在雨季；速效氮的时间变化与铵态氮类似，5月出现明显低谷；水解氮表现为小幅度的不规则波动，总的走势为平稳下降，全年没有明显高峰。

At large scale, the result of comparing of optimization structure of forest type with the present structure of forest type illustrates that the present economical forest area is larger while the mixed forest is smaller. So decreasing economical forest area and increasing mixed forest area should be the main measurements to optimize spatial patterns. At small scale, the evaluation of the landscape inner structure index illustrates that the forest structure and coverage is smaller, which should be regulated and so the uneven-aged, multi-layered and mixed forest should be the object of the forest structure design.

大尺度上根据植被类型优化结构和现有植被类型结构数据的对比分析可知，现有经济林面积则过大，混交林面积较小，因此主要是减少经济林面积，改造针叶和阔叶纯林为混交林，从而增加混交林面积，以达到最优植被类型结构时的空间配置；在小尺度上通过对景观内部结构指数的计算分析可知，该区林分结构和郁闭度分指数值较小，应予以着力调整；由研究结果可知，异龄、多层次、混交的水源保护功能最好，因此稳定的林分结构设计目标就是尽量使林分形成异龄、多层次、混交林。
