1·Methods The filter device of reserved veinal infuser was invented by ourselves and it was used in clinic.

方法自行研制了带过滤装置的静脉留置针并用于临床。

2·An incr eased leaf weight ratio (LWR) and inter-veinal chlorosis evidenced in boron deficient leaves may indicate excessive carbohydrate accumulation, leading to a decline in chlorophyll content.

缺硼也提高叶片重量比(LWR)并导致叶脉间失绿，说明缺硼叶片可能过量碳水化合物积累，引起叶绿素降解。
