In addition, the coverage and number of carbon layers in CCA can be easily controlled by changing the sucrose content in the precursors and the impregnation times. 在這種復合材料中，碳層厚度可控制為一個(gè)石墨單層的厚度，且碳的覆蓋度及層數可以通過(guò)改變浸漬的蔗糖量及浸漬次數來(lái)進(jìn)行調控。
So that's more tests, more time for developers to run the test suite, and more chances of missing code coverage, especially when different modes interact. 也就是要寫(xiě)更多的測試，開(kāi)發(fā)者要花更多的時(shí)間來(lái)運行測試套件，并且更有可能達不到代碼的測試覆蓋度，特別是當不同模式相互作用時(shí)。
