" The fact that cancer deaths are now twice as frequent as CVD deaths in high-income countries, " Yusuf said, " shows a change in the main cause of death in middle-aged people" .

" 在高收入国家，癌症是心致死的两倍，这一事实表明，中年人死亡的主要原因发生了变化。"

However, the news is not that cancer deaths are increasing but that deaths from cardiovascular disease (CVD) are decreasing.

然而，这并不是因为癌症死亡人数在持续增加，而是心（称CVD）死亡人数在不断减少。

In CVD, diamond seeds are arranged on a surface that's placed into a chamber which is filled with gases.

采用化学气相沉积法时，工作人员会将金刚石籽晶排列在一个基底上，再将基底放入充满气体的反应室中。

The other key technology used to make synthetic diamonds is chemical vapor deposition, or CVD.

另一项制造人造金刚石的关键技术是化学气相沉积法（称 CVD）。

CVD is typically used to make synthetic diamonds for high tech applications, like optics, thermal management for high power devices, or quantum technology.

化学气相沉积法通常用于制造高科技应用所需的人造金刚石，例如光学元件、大功率设备的热理部件或量子技术相关器件。

CVD gives scientists more specific control than high pressure high temperature reactors, but the growth rates are much slower.

与高温高压法相比，化学气相沉积法让科学家能进行更精确的控制，但生长速度要慢得多。
