In a second aspect, this invention provides a surface-mount inductive loop detector including: an inductive loop which is adapted for connection to an external electronic controller device; a protective cover in the form of a substantially inflexible ring having a hardened, bevelled peripheral edge; said ring adapted to accommodate the inductive loop between a mounting surface and a lower surface of the ring and provided with means for fixing the detector to the mounting surface.

在第二方面，本发明提供一种表面安装感应环检测器，包括：感应环，该感应环适用于连接到外部电子控制器设备；保护罩，该保护罩为具有基本上呈柔性的圆环，该圆环具有硬化的、倾斜外周缘；所述圆环适用于容纳位于安装表面和圆环下表面之间的感应环，并设有用于把检测器固定到安装表面的装置。

In this thesis, we shall study the isomorphism property of chordal ring networks and we shall find out the diameter of some directed chordal ring networks and the diameter of some mixed chordal ring networks.

在这篇论文里，我们首先推导「有向的弦环式网路」以及「混合的弦环式网路」的同构性质；我们接著得出某些特殊的「有向的弦环式网路」以及「混合的弦环式网路」的直径，与之前文献不同的是，我们并不需要先计算出对应的「双环式网路」的直径来得出这些直径。

While the diameter of an undirected chordal ring network has been well studied [1], the diameter of a directed chordal ring network and the diameter of a mixed chordal ring network are not known.

虽然「无向的弦环式网路」的直径已被完整地研究、并且可以运用公式得出，但是截至目前为止，「有向的弦环式网路」的直径、以及「混合的弦环式网路」的直径却还未被完全找出来。

Through block wall experimental study we can find out that cracks would appear late and the load of crack-resisting and limit-resisting are increased obviously by the constructional measures in the wall. It is very effective method that the splayed cracks are controlled by sill ring beam, the horizontal bending cracks are controlled by structural column on the side of the wall and the horizontal cracks on the top of the wall are controlled by the whole ring beam. It is the most effective method that wall cracks are controlled by structural column, crout column and sill ring beam.

通过试验主要得到在墙体中采取构造措施后，墙体裂缝推迟出现，开裂荷载和极限荷载都有很大程度的提高，同时发现窗台圈梁在控制窗角的八字缝、墙体两侧构造柱对于防止水平弯曲缝以及全截面的圈梁在防止墙体和圈梁交界处的裂缝的出现能起到很好的效果，通过试验确定在砌块墙体中采取&构造柱+芯柱+窗台圈梁&的构造措施来控制裂缝是最为经济合理有效的。

To discover new strobilurin analogues with high pesticidal activity, a series of new strobilurin derivatives containing substituted pyrazole and pyrimide ring, which included 124 novel compounds (73 compounds containing substituted pyrazole ring and 51 compounds containing substituted pyrimide ring) were designed and synthesized. In addition, 36 new intermediates were synthesized. Their structures were characterized by ~1H NMR and elemental analysis, partial compounds were characterized by MS and IR once again.
