Since the requirement is to only suppress nulls, the visual null suppression can be replaced by the null suppression on the actual query.
因为需求是仅抑制nulls，可视的null suppression可由实际查询上的null suppression替换。
In addition the queries which are sent to remote data sources are further optimized by the execution layer based on cache content and advanced null suppression logic.
另外，被发送到远程数据源的查询由执行层根据缓存内容和高级空抑制逻辑进行进一步优化。
But for weak interference, because the null formed by power inversion array is shallow, the performance for suppression of interference is poor.
但对于弱干扰源的情况，该算法形成的零陷不够深，对干扰的抑制有限。
