Results:The length of the tendon of biceps brachii short head was 8. 7 ± 1. 5cm,0. 9±0.4cm the width was(in upperparr) ,1.2 ± 0.4cm (in middle part) and 1.4 + 0. 4cm(in lower part). The distance was 4. 7 ± 0. 5cm between the coracoid process tip and the acromial end of clavicle.
They perforated the deep fascia (4.1 ± 0.5 ) cm proximal to the intermalleolar, (1.4 ±0.2) cm proximal to the medial of the first metatarsophalangeal joints and (1.5 ± 0.3) cm proximal to the tip of the great toe webspace, respectively.
(3) The semi-quantity RT-PCR was used to study mRNA transcriptional model of KGF, IGF-1, IGF-2, BMP-2, BMP-4 on pestile (A), proximal growth tip (B), intermediant growth tip (C), distal growth tip (D), and middle regions (E-I) of the same antler tissue.
The effect on the adhesion between the tip and GeSb2Te4 film caused by humidity was more significant than that between the tip and Ge2Sb2Te5 film, and the presence of adhesion can change the friction coefficient.
Tantalum nitride field emitter was fabricated by nitrifying a tantalum tip, which gave an electron emission current of 210μA at the tip voltage of 6.8 kV and the temperature of 1300 C, with a brightness of 3 × 108 A/cm3·str and an angular current density of 5×103μA /str.

AFM-tip-induced crystallization of poly(ethylene oxide) melt droplets
The AFM-tip-induced crystallization of poly(ethylene oxide) (PEO) melt droplets was studied.
For the PEO samples with average molecular weights (Mn) ranging from 1.0 × 103 g/mol to 1.0 × 104 g/mol, the lateral perturbation from the AFM tip in the hard-tapping or nanoscratch modes could not induce the growth of the flat-on lamellae.
In contrast, under AFM nanoindentation mode, the tip-induced crystallization occurred when a sufficiently high vertical tip force was applied to the melt droplets of PEO with Mn ? 1.0 × 104 g/mol.
Moreover, the experimental results indicated that the AFM-tip-induced crystallization of PEO in the nanoindentation process had molecular weight dependence.
