Public void add (TreeNode node) {, lobster habits. Lobster belongs to insect shell animals, similar to crabs, with a pair of specially developed chelates and the habit of digging caves. Generally, lobsters dig caves near the water's edge. Lobsters like shade and fear light. When the light is weak or dark, they climb out of the cave. When the light is strong, they sink to the bottom or hide in the cave. Lobsters have spawning periods twice a year in spring and autumn. A pair of male and female lobsters can breed up to 480 shrimp seedlings at a time. Usually, the lobsters listed in early spring are the shrimp larvae bred in the autumn of last year, while the shrimp larvae bred in spring only need to be bred for more than 60 days to be listed. Lobster farmers only need to keep the large whole lobster for planting in the first year. In autumn, the lobster will go into the cave to give birth. In the second year, they do not need to buy too many lobster seedlings. 2. Big appetite and miscellaneous eating habits. Lobster has a very good appetite and can be fed with animal and plant feed, such as miscellaneous fish, miscellaneous meat, wheat, corn and other wild omnivores. 3, not afraid of dirty and smelly water, afraid of chemicals. Lobster is not afraid of dirty and smelly water, but it is very sensitive to chemicals such as pesticides, fertilizers and liquefied petroleum gas. As long as there are these chemicals in the pond, the lobster will be destroyed. Second, lobster breeding technology 1, to create a good lobster growth environment. Lobsters like to make holes. Generally, the depth of caves is 50-80cm, and the depth of some caves is more than 1m. In order to avoid escaping from the holes, the width of the ridges around the aquaculture water body should be more than 1.5 m, and 0.5 m high anti-escape nets or smooth anti-escape walls and anti-escape boards should be set up around the ridges. The anti-escape boards and fences should also be buried 2m deep to prevent lobsters from escaping. At the same time, the river pond simulates the ecological environment of lobster under natural conditions.书生见他吃得满嘴是油，心情也很好，他自己只简单吃了些蔬菜，微笑问道：可好吃？玉米把啃完的鸡脚往桌上一扔。 3×02 《Guardians》：Cole和Jones前往第一次世界大战结束后的法国寻找Jennifer Goines，他们遭遇一个危险的时间旅行团队：「守护者」（Guardians）。For spoofing attacks, the first thing to consider is to choose the address. For the attack to succeed, the host on the spoofed IP address must not respond to any SYN-ACK packets sent to them. A very simple method that an attacker can use is to disguise only one source IP address, and this IP address will not respond to SYN-ACK packets, perhaps because there is no host on this IP address at all, or because some configuration has been made to the address or network properties of the host. Another option is to disguise many source addresses, and attackers will assume that hosts on some of these disguised addresses will not respond to SYN-ACK packets. To implement this method, you need to recycle the addresses on the list of source IP addresses that the server wants to connect to, or make the same modifications to hosts in a subnet.Experts said that the ideological value of the three worlds is as follows: "Chairman Mao Zedong's correct strategy of dividing the three worlds has provided a powerful ideological weapon for the international proletariat, socialist countries and oppressed nations to unite as one, to establish the broadest united front, and to oppose the Soviet Union and the United States and their war policies.
