    摘要： A probe rod is inserted into a water main through a corporation cock. The rod has a plurality of transverse passages parallel to one another and aligned in the direction of flow. Within these transverse passages, in flush relationship to the passage walls, are inserted removable sampling rings. All but one of the rings are of the same material as the inner wall of the main. The remaining ring, used as a control, is a synthetic resin ring. The flush relationship prevents the formation of turbulent eddies at the ends of the rings. Consequently, microbial growth conditions on the rings themselves reliably simulate conditions on the interior wall of the main.Within a tubular extension on the exterior of the corporation cock an O-ring seal is provided. The length of the extension, and the position of the seal, are such that the probe rod can be partially withdrawn beyond the corporation valve without causing any of the transverse passages to pass through the O-ring. Thus, the rod can be partially withdrawn, and the corporation valve closed before the rod is fully withdrawn. Because of the length of the extension and the position of the O-ring, partial withdrawal of the probe rod can be accomplished without scouring of the sampling rings due to high velocity flow of water through the transverse passages as they move through the O-ring.

    摘要翻译： 探针杆通过公司公鸡插入水中。 杆具有彼此平行并沿着流动方向对准的多个横向通道。 在与通道壁平齐的这些横向通道内插入可移除的取样环。 除了一个环之外，所有的环都是与主体的内壁相同的材料。 用作对照的剩余环是合成树脂环。 冲洗关系防止在环的端部形成湍流涡流。 因此，环上的微生物生长条件本身可靠地模拟主体内壁上的状况。 在公司外壳的管状延伸部内设有O形密封圈。 延伸部的长度和密封件的位置使得探针杆可以部分地从公司阀外部抽出，而不会使任何横向通道穿过O形环。 因此，杆可以部分地撤回，并且在杆被完全拉出之前公司阀关闭。 由于O形环的延伸长度和位置，探针棒的部分抽出可以在水通过O形环时通过横向通道的高速流动导致取样环的冲刷而实现。 。

    摘要： A method for controlling zebra mussels in aqueous systems comprising treating aqueous systems which contain zebra mussels or which are prone to zebra mussel infestation with an effective amount of a composition comprising a) a water-soluble dialkyl diallyl quaternary ammonium polymer (polyquat); and b) didecyl dimethyl ammonium halide. A preferred polymer is a poly(quaternary ammonium) compound having the recurring structure [DMDAAX.sup.- ] resulting from the polymerization of monomeric dimethyl diallyl ammonium X.sup.-, wherein X.sup.- is any suitable anion.
