A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey, and may include oversimplified elements in order to make this essential meaning easier to grasp, as well as additional ...
Picea meyeri (Meyer's spruce; Chinese: 白杄; pinyin: báiqiān) is a species of spruce native to Nei Mongol in the northeast to Gansu in the southwest and also inhabiting Shanxi, Hebei and Shaanxi. It is a medium-sized evergreen tree growing to 30 m tall, and with a trunk diameter of up to 0.8 m. The shoots are yellowish-brown, glabrous or ...
Sitka spruce is a long-lived tree, with the oldest known individual just under 600 years old. [7] Because it grows rapidly under favorable conditions, large size may not indicate exceptional age. The Queets Spruce has been estimated to be only 350 to 450 years old, but adds more than a cubic meter of wood each year.

Schematic capture or schematic entry is a step in the design cycle of electronic design automation (EDA) at which the electronic diagram, or electronic schematic of the designed electronic circuit, is created by a designer. This is done interactively with the help of a schematic capture tool also known as schematic editor. [1]
Picea × lutzii is a hybrid spruce tree that is a natural cross between white spruce and Sitka spruce occurring where the ranges of the two species overlap in coastal south-central Alaska and coastal British Columbia. Its common name is Lutz spruce. Its morphology is intermediate between the two parent species, the maritime Sitka spruce and the ...
Old Tjikko [a] is an approximately 9,567-year old Norway spruce, located in the Dalarna province in Sweden. Old Tjikko originally gained fame as the "world's oldest tree".

Wood used for this purpose is referred to as tonewood. Spruce, along with cedar, is often used for the soundboard/top of an acoustic guitar. The main types of ...
