Today, players use specially developed rubber-coated wooden and carbon-fibre rackets and a lightweight, hollow celluloid ball.

最早，乒乓球的球拍是用雪茄烟盒盖做成的，球是香槟酒软木塞雕成的；今天的球员使用的是特别研发的木质或碳纤维球拍和轻质塑胶空心球，在球拍上使用的各种合成橡胶和胶水可以增加球的旋转和速度。

The game, which debuted in the Olympic Games in 1988 at Seoul, began with cigar-box lids for rackets and a carved champagne cork for a ball. Today, players use specially developed rubber-coated wooden and carbon-fibre rackets and a lightweight, hollow celluloid ball. Various rubber compounds and glues are applied on the rackets to impart greater spin or speed.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
