If you mean that reset pin has little circle at it's base, then no. Circle at pin's base means logic inversion of pin, or active low state. In other terms it is denoted ad RESET with line above letters (not sure how to write it in bbcode). This means that device resets when reset is brough low. In case of 8051 reset is not inverted so device resets when RST pin is brough high. This means that you need an inverter. You can make such with single general purpose bipolar transistor (like bc547, bc847, 2n2222, 2n3904 and such) +some resistor in series with base (2k?) + pullup resistor in order of 10k from reset pin to vcc. You may also add 100nF capacitor from reset to gnd to improve noise immunity and prevent accidental resets caused by transients.
