When no angiogenesis, solid tumor growth will Be inhibited so obviously that it is limited to carcinoma or tiny metastasis of several hundred micra; on the contrary, if having angiogenesis, tumor will grow rapidly, whacs more, its nature of soakage and metastasis will be enhanced greatly.

新生血管为肿瘤的生长、转移提供氧和营养物质，在无新生血管生成时，实体肿瘤的生长明显被抑制，只局限于原住癌或几百个微米的微转移；而一旦新生血管长入，肿瘤将迅速生长，且浸润和转移的能力大大加强。

In the field of Microelectromechanical Systems, with the request of improving device parameters, the device dimensions are scaling down to submicrons and even nanometers, which causes the appearance of a new concept based on MEMS technology-Nanoelectromechanical Systems.
