Weinkauf et al[1] proposes a glyph representation for high-order vector singular points.
This is done by having two methods, one with order p and one with order p-1.
We give each ball a number from 1 to N.
With an interval n drawing a glyph, they are numbered 0, 1, 2, ..., N, until the end of the streamline .

The main specific component of industrial 7075 aluminum alloy is shown in Table 1.
At this time, the graphite electrodes (10mm diameter) could be also immersed in the molten Al-alloy and then switched on electric pulse current, as shown in Fig.1.

Fig. 1 Architecture of 6LoWSN Shown in Fig. 1, IEEE 802.15.4 standard is used as the underlying specification in 6LoWSN which defines physical radio channel and media access layer interface.
“LS” is calculated as following: (1) In Equation (1), “Li” is the waiting queue length of node vi, and “Len” is the total length.
If it is heavy-load, the RREQ packet is discarded; if not, the value of “LS” is modified according to Equation (1), and the address of this node is added to RREQ routing record, then forwards the RREQ packet normally.

In this study, a series of tests which focus on the applied technique of the composite geo-membrane in the second stage cofferdam were performed [1].
Based on a series of tests, the recommended mixture proportion of the plastic concrete applied in the cutoff wall of the second stage cofferdam in the Three Gorges Dam is shown in Table 1.
