Owing to the key conclusion, this paper lays emphasis on the possible ways of realizing the singular conjugation by single—enveloping method. It is proved that the hyperbolic normal arc surface and the involute helicoid both may conjugate in singular points on the condition of single—envelope.

But as Lou Crandall of Wrightson ICAP, a research firm notes, Auctions work well when you have a group of bidders for a single set of identical assets. They work less well when you have a single bidder for a group of disparate assets.

但是一家研究機構Wrightson ICAP的Lou Crandall認為：拍賣在一群競標人爭奪一個單一的資產(chǎn)時比較有用，但是在一個競標人卻又一大堆不同的資產(chǎn)時就不太起作用了狂插乱捅。

Based on the foundation of the virtual prototype model of the medium-speed maglev train, using the mechanical dynamics and kinematics analysis software ADAMS, this paper expatiates on the following things. Firstly, it analyses the decouple of single magnetic bogie by the simulation and experimentation; secondly, adds the magnetic levitation control system to the single magnetic bogie model and simulates; thirdly, by simulating the motion of the train running on the different type of guideway, analyses the state of the train on the ramp and crankle;in the end ,this paper does a further research on how the magnetic levitation control system and guideway parameters affect the suspending gap when the train runs on the ramp and crankle .

Results: In all 13 patients, non-contact mapping showed AFLs confined to the RA with the cycle length (230 ±20 ms). 6 patients presented single-loop re-entry circulating around the central obstacle in the anterolateral wall through the channel between the CO and the crista terminalis .Seven patients presented "8" re-entry, and the gap of upper and lower loop located in CT in 4 cases, another 3 cases with upper loop and free-wall single-loop re-entry. RF of CT gap and/or the free-wall channel was effective in eliminating these AFLs in 13 patients.

There isn"t obvious selectivity in blank cutworm imperilment, the onseting quantity and imperilling degree is similar on different crops. It"s more serious in the field of invasion of weeds and corn intercrop potato than single cropping of corn, and the field of forecrop green manure is more serious than single cropping. Imperilment degree of black cutworm is very serious in both high altitude region as Dewu (1780 meters) and low altitude region as Lemin (1450 meters). The imperilment degree in two regions have no obvious differences. 4. The imperilment of second generation armyworm is very serious in both high altitude region of Dewu and low altitude of Lemen town.

This paper introduces a single-carrier system with hybrid time-frequency domain Decision Feedback Equalization, in which the short pn (Pseudo-Noise) sequence with fixed waveform replaces the cyclic prefix in the conventional Single Carrier systems with Frequency Domain Equalization, and the long PN sequences composed of several short pn sequences are employed as the channel training sequences to complete the initial estimation and tracking for fast-varying channel.
