介绍（中）	岩芯是一种石头，从中取出薄片，以便将薄片制成工具。这是用一种称为Levallois核心制备的特殊技术制成的，该技术在旧石器时代中期被广泛使用。与旧石器时代晚期相比，旧石器时代中期出现了更复杂的石器技术，工具类型也更加多变。这种变化与人类行为的日益复杂有关 - 例如专门的狩猎，烟火技术和符号的使用 - 最终导致解剖学和行为上的现代人类。Levallois芯是通过以特定方式去除薄片制成的，例如围绕边缘向心，因此最后分离的薄片具有预定的形状。这个例子是"努比亚A"型的勒瓦卢瓦岩心，其中准备片从远端（尖头）端移除，以创建一个中央脊，产生尖片。
介绍（英）	A core is a stone from which flakes have been detached so that the flakes can be made into tools. This one was made with a special technique called Levallois core preparation that was widely used during the Middle Paleolithic Period. The Middle Paleolithic saw the rise of more complex stone tool technologies and more variability in tool types compared to the Lower Paleolithic. This change is associated with the increasing complexity of Hominin behavior —such as specialized hunting, pyrotechnology, and the use of symbols— eventually resulting in anatomically and behaviorally modern humans. Levallois cores were made by removing flakes in a specific way, such as centripetally around an edge, so that the last flakes detached have a predetermined shape. This example is a ‘Nubian A’ type of Levallois core where preparation flakes were removed from the distal (pointed) end in order to create a central ridge that will produce a pointed flake.
