【正文】 膀：三順＋同數(shù)量的一套牌。例如： 333444+69 或333444555+667799 畢業(yè)設(shè)計(jì) 35 ◆ 四帶二：四張牌＋任意兩套張數(shù)相同的牌。例如： 5555＋ 3＋ 8或 4444＋ 55＋ 77 牌點(diǎn)大?。? 大王 小王 2AKQJ109876543 牌套的大?。? ◆ 火箭 什么牌型都可打，是最大的牌。 ◆ 炸彈，除火箭和比自己大的炸彈外，比其它牌型都大。 ◆ 對(duì)其他牌套而言，只有當(dāng)牌套和總張數(shù)相同的牌，才可比較大小。 ◆ 像三帶一、四帶二等組合 牌型，只要比較其牌數(shù)最多牌的牌點(diǎn)就行。 有效炸彈或火箭： 如果發(fā)牌時(shí)直接發(fā)出炸彈或火箭，計(jì)分時(shí)不翻番。即不是直接發(fā)牌出的炸彈，而是用來滅其他牌時(shí)使用的炸彈才有效，計(jì)分時(shí)才翻番。 一幅牌游戲過程： 開牌： 游戲開始時(shí)，由打牌服務(wù)器將一副牌隨機(jī)留三張底牌，其他牌隨機(jī)發(fā)給三家。開牌過程是自動(dòng)完成的。 叫牌： 第一局首個(gè)叫牌人由系統(tǒng)隨機(jī)指定，以后每局按逆時(shí)針順序輪流開始叫牌。每一局每人只能叫一次，叫牌可叫“ 1分”、“ 2分”、“ 3 分”或不叫，叫最大分的玩家為地主，如果都選擇不叫牌，則重新開始一局。 如果有人“叫牌”直接 叫“ 3 分”，后面的玩家就沒有“叫牌”機(jī)會(huì)了。“叫牌”分最高的玩家就是本局的“地主”，其他兩位玩家是一伙聯(lián)合起來和地主斗。地主確定后，將三張底牌亮明，所有玩家都能看到，并且將三張底牌交給地主。這樣地主手中有 20 張牌，另兩位玩家手中只有 17 張牌。 基礎(chǔ)分： 地主所叫的分值。 畢業(yè)設(shè)計(jì) 36 發(fā)牌： 每局牌都由地主先發(fā)牌。以后每輪都由上一輪的最后出牌人發(fā)牌。 上牌： 有人出牌后，其他玩家按逆時(shí)針順序依次跟牌。輪到玩家跟牌時(shí)，可選擇不跟，或者用比所出的牌大的牌套管住，稱為上牌。 過牌： 對(duì)前面人出的牌不跟，稱為過牌。 一輪結(jié)束： 一輪牌中當(dāng)某玩家出牌后，其余兩位玩家不再跟牌時(shí)，此輪結(jié)束。下一輪牌由該玩家先發(fā)牌。 一局結(jié)束： 當(dāng)一玩家手中的牌全部打光時(shí)，一局牌結(jié)束，開始定勝負(fù)。 定勝負(fù)： 如果地主第一個(gè)出完牌，地主贏；否則，地主輸。 一幅牌計(jì)分： 基礎(chǔ)分：叫牌的底分，有“ 1分”“ 2分”“ 3 分”； 地主勝：地主得 2 叫牌的底分，其余兩家各得： — 叫牌的底分； 地主敗：地主得 — 2 叫牌的底分，其余兩家各得： 叫牌的底分； 每出一個(gè)有效炸彈（或火箭），分?jǐn)?shù) 2 ； 地主把牌出完，其余兩家一張牌都沒出，分?jǐn)?shù) 2 ； 兩家中有一家 出完牌，而地主僅僅出過一手牌，分?jǐn)?shù) 2 。 Visafree policy brings Chengdu biz, tourism boost. Making national headlines several times, Chengdu39。s 72hour visafree policy has attracted wide attention from both Chinese and foreign experts and businessmen since it took effect on Sept 1 last year. The program permits citizens from 51 countries and regions including the United States, Australia, Canada and Japan who have valid visas and flight tickets to a third country to spend three days in the city. The capital of Sichuan pro vince is the first city in the western region of China to offer foreign tourists a threeday visa and the fourth nationwide to adopt the policy following Shanghai, Beijing and Guangzhou. Li Zhiyong, deputy dean of the tourism 畢業(yè)設(shè)計(jì) 37 institute at Sichuan University, said the move contributes to a large increase in the number of overseas tourists and raises the city39。s level of internationalization. The policy will also bring direct economic revenue, Li said. Chengdu has many cultu ral legacies and is also a paradise for panda lovers with the world39。s largest breeding and research center. Three days are long enough for foreign visitors to visit those iconic tourist spots, he noted. The city is home to the remains of the Jin sha civilizat ion that dates back more than 3,000 years as well as the Qing cheng Mountains and the Du jiang yan irrigation system. Qing cheng has long been recognized as the birthplace of Taoism, China39。s ancient indigenous religion, while Du jiang yan is considered to be the oldest functioning watercontrol project in the world. Chengdu ranked third in tourist facilities, management and services among 60 Chinese cities in a customer satisfaction survey released last year. But, Li added that efforts are still needed to develop more tourism products, improve English services and provide accurate translation of traffic signs and scenic billboards. Zhao Yun, chairwoman of British Chamber of Commerce Southwest China, told China Daily that his colleagues found the policy very convenient. A British client once flew here and stayed for just one day to check her ordered goods, she said. Zhao was born in Shanxi province, but she has lived in Chengdu for more than 10 years. My life was like a running race moving from place to place. I also lived in Beijing and Shanghai before, she said. But Chengdu is a place that you never want to leave once settling down. It is now my second hometown, she said. If the environment is further improved, the city will attract more people to visit and live, with the 72hour visafree policy and pelling conditions in transportation, culture, climate and cuisine, he said. Foreigners also gave positive feedback on the policy. A spokesman from Dell Inc said the pany has a global hub of operation in Chengdu, so the three day visa has an immediate and positive influence on the pany39。s business development. Rudy Buttignol, president of the public broadcasting pany in British Columbia, Canada, said his work requires frequent travel to Chengdu and the policy makes the trips easier. Data from the city39。s public security bureau shows some 100 foreign visitors enjoyed the 72hour policy by the end of March, most of them from the United States, the United Kingdom and Germany. Chengdu also reported robust growth in its overall tourist industry last year. Official statistics show that it received some 150 million tourists last year, an increase of 28 percent from 2020. Around million came from abroad, an increase of 12 percent. Total revenue from tourism surpassed 133 billion yuan ($). During his visit to Kazakhstan in September, Chinese President Xi Jinping proposed that China and Central Asia join hands to build a Silk Road economic belt to boost cooperation. The idea has been widely echoed in Central Asian countries, being an encouraging blueprint for Chinese areas along the Silk Road that has linked Asia and Europe for more than 2,000 years. In the next three weeks, China Daily reporters will travel through the belt in China and in Kazakhstan, Uzbekistan and Turkey. They will show the progress and expectations of the countries, businesses and peoples on the route. Shaanxi the start of the ancient Silk Road has positioned itself as the new starting point for the development of the Silk Road Economic Belt, which will strengthen China39。s cooperation with Central Asian countries, a senior official said. Shaanxi Governor Lou Qinjian said the province is fresh, rich and unique, as it was when it anchored one end of the ancient Silk Road. It is the best option for acmodating industrial transfers from East China or the world at large, he said on Wednesday in Xi39。an. Lou held a joint interview with 27 media, including China Daily, the first in a series of interviews entitled Chinese Media Along the Silk Road. The interviews will be in Shaanxi and Gansu provinces and the Xinjiang Uygur autonomous region, as well as Kazakhstan, Uzbekistan and Turkey. The media group held the first interview on Wednesday morning in Xi39。an, the starting point of the ancient Silk Road, a trade channel established more than 2,000 years ago linking China, Central Asia and Europe.
