The principal best management practices for Costa Rica are: a well drained soil or a good drainage system in the field (banana yield is hurt with only a few hours of oxygen depletion in the root zone), b adequate control of nematodes, c adequate control of black sigatoka and d a good fertilizer program which includes rates of fertilizer equal or higher than 300-300-600 kg/ha/year of N- P2O5- K2O split in 12 applications during the year.

这些最好的管理措施为： a ）良好排水土壤或田间良好排水系统（根区缺氧几小时就会损害香蕉产量）， b ）有效地防治线虫， c ）有效地防治香蕉叶斑病和 d ）良好的施肥计划，施肥量等于或高于300-300-600公斤 N - P2O5- K2O /公顷/年，一年中分12次施入。

The sinal from the active recording electrode was shunted to another EMG-computer set for analysis of the same motor unit by adding a surface electrode as a reference electrode (monopolar needle recording pattern).

By assuming that the scattered radiation tends to be a spatially slow-varying function, the scatter components at LOR blocked by each stopper can be estimated and the whole scattered sinogram can be recovered using interpolation from these local measurements.

在假设散射分布为一缓慢变化函数的前提下，根据两次妇描与空气妇描的资讯，可以求得被档块阻档部份的散射分率，并利用cubic spline内插法回复出整个散射分布，以达到散射矫正之目的。

This method is also available for other problems of unsteady flow around complicated bluff bodies at medium or high Reynolds numbers and the results are used as reference for wake control The phenomena of the sinusoidally oscillating flow past a circular cylinder are also studied.
