The results indicated as follows:the total nutrient elements accumulation of various Slash Pine stands amounted to 1273.83-1615.88kg/hm2,of which stem occupied about 60%. The nutrient retention accounted for 111.46-133.39kg/hm2*a,which is higher than that of either Chinese fir or Masson pine plantation. The nutrient return equalled to 90.43-105.09kg/hm2*a. Nutrient elementsturnover period is long while cycling rate is lower. The net production per ton needs 13.19-14.81kg nutrient.

结果表明：湿地松林分中养分元素总积累量为1273.83-1615.88kg/hm2，树干约占60%，积累速率为111.46-133.39kg/hm2*a，高于杉木和马尾松，归还量仅有90.43-105.09kg/hm2*a，其周转期长，养分循环速率低，每生产1t有机物需要上述养分元素共13.19-14.81kg。

Despreading the array receiving signal with the spread spectrum sequence being orthogonal to user's, and the coefficients of the channel FIR filter are then adjusted by CM algorithm adaptively to compensate the errors.

在天线阵列附近，发射扩谱序列正交于用户信号的同频辅助信号，用辅助信号对阵列接收信号解扩，采用恒模算法自适应的调节阵列通道滤波器参数，达到补偿阵列误差的目的。

The mathematical orthonormal function is introduced into the structure of filter. Prior information of the system is obtained by mapping the system model to orthonormal basis function.

该滤波器引入正交函数理论，利用系统模型与正交基函数之间的关联，预先获取系统的先验信息，从而兼有FIR和为IIR两者的优点。

The design of finite impulse reponse filters which is based on the window function may produce oscillation for the non-uniform convergence of the filter, which affects the precision of the filter,but improvement on the precision need increase the calculation amount,which is unfavorable to the real-time system.

用窗函数法设计FIR滤波器，由于非一致收敛而产生振荡，从而影响了滤波器的精度，而提高精度是以增加计算量为代价的，对于实时系统是很不利的。

I was encouraged with this, and I had my Patroon's Antient on Board, I made a Waft of it to them for a Signal of Distress, and fir'd a Gun, both which they saw, for they told me they saw the Smoke, tho' they did not hear the Gun; upon these Signals they very kindly brought too, and lay by for me, and in about three Hours time I came up with them.

我船上本来就有我们原主人的旗帜，我就拿出旗帜向他们摇起来作为求救的信号，同时又鸣枪求救。这两个信号他们都看见了，因为，后来他们告诉我，枪声他们虽然没有听到，但看到了冒烟。他们看到了信号，就停船等我们。他们的这个举动真是仁慈极了。大约过了三小时光景，我才靠上了他们的大船。
