"No one in position 149 was completely unstung, I am no exception, He got several times during the fight, But I'm lucky, None of them stung the key parts, Two big flying wasps stung me in this area of my chest. Luckily there was a bullet bag hanging on it, The bullet bag was stuffed with four shuttles (note: the shuttle here refers to the magazine of an automatic rifle). Four shuttles covered the whole chest, So it blocked the two poison needles directly, No matter how severe the poison needle is, of course it cannot penetrate the shuttle. Just pierced the canvas on the bullet bag, It was hung on it, but although it could not be tied through the shuttle, it could still pass through the slightly thinner metal, because I had been hit several times in my head. When the battle was completely over, I had five poisonous needles on my head, each of which was the front tip already stuck in and the back half was exposed. I was wearing a helmet at that time! Even helmets can be tied up. No wonder several comrades with cloth hats have their skulls nailed through.In real life, China's income tax is divided into enterprise income tax, foreign-invested enterprises or foreign-invested enterprises income tax and personal income tax. For these three types of income tax, each is calculated in a different way. Personal income tax has a personal income tax calculation method, while enterprise income tax has its corresponding calculation method. If we do not adopt the policy mode to realize such a requirement, we will define an income tax class, which has an attribute to identify the type of income tax and a CalculateTax () method to calculate the tax. In this method, we need to judge the tax type and calculate the income tax for different tax types through if-else statements. Such an implementation can indeed solve this scenario, but such a design is not conducive to expansion. If the system needs to add an income tax in the later period, it has to go back and modify the CalculateTax method to add an additional judgment statement, which clearly violates the principle of "open-closed". At this time, we can consider using the strategic mode to solve this problem. Since the tax method is the changing part of this scenario, we can naturally think of abstracting the tax method at this time, which is also the essence of the implementation of the strategic mode.Earlier this year, a blackmail software called "WannaCry" began to attack the Internet, from Chinese universities to British hospitals. In April this year, IDT, a Newark, New Jersey-based telecommunications company, suffered a similar attack, which was discovered by Goran Ben-Oni, the company's global chief operating officer. As Ben Oni said in an interview with the New York Times, he immediately realized that this blackmail software attack is different from other attacks against companies. It not only steals the information in the databases it infiltrates, but also steals the information needed to access these databases. This kind of attack means that hackers can not only obtain this information quietly, but also continuously monitor who accesses this information.“豆腐西施“杨七巧与丈夫钱满贵路遇一弃婴。她把女婴抱给了结婚八年没孩子村长小舅子包有才，但却遭到一贯强势的村长媳妇包玉兰的坚决反对。出于对孩子的怜悯，七巧决定自己收养，取名杨小爱。后又发现自己怀孕了，她背着家人做了人流。婆婆闻讯，心脏病复发抢救无效。七年后，杨七巧的祖传豆腐生意越做越火，这一切遭到了结怨多年的包玉兰的忌妒，更抢了包玉兰表妹，同样在城里做豆腐生意的包香兰的生意。她们处处与七巧做对，步步刁难，七巧举步为艰……天有不测风云，小爱突然患了肝坏死七巧决定卖掉生意为孩子治病。夫妻俩产生了冲突。为了解决肝脏源，她把小爱的身世登在报上。七巧终于等来了小爱的生母——竟是生意场上处处为难自己和孩子的包香兰。第二季已完成剧本阅读，现在正式进入拍摄阶段，预计将于明年二月中播出。汪老三见前冲的势头阻住了。本剧的故事围绕汇集了最优秀专家和最先进设备仪器的警方罪案鉴证中心展开，以何书杰、秦朗为首的一群警官，他们毕业于刑警学院和医学院等高等学府，掌握着法医学、遗传学、生物学、人类学的尖端知识和技术，怀着对罪案鉴证事业的热爱，奔走于各个刑事犯罪现场，进行犯罪现场调查和重建，战斗在没有硝烟的战场。他们常常面对冰冷的尸体和无言的物证，为案件办理提供科学严谨的证据，他们的鉴定结论和检验意见决定着案件的侦查方向甚至是直接认定和否定罪犯。他们虽然没有直接面对穷凶极恶的犯罪分子，却要常常忍受常人所无法忍受的恶劣工作环境，勘察、解剖高度腐败的尸体，承受被微生物侵害健康的危险，还要在诸如电击、爆炸、矿井、煤气泄露等现场，遭遇电击、中毒等危险。在这样的工作中，他们不仅有大夫治病救人、严细认真的医德，更展示了秉公执法、不畏权势、察微析疑、科学鉴定的意志和品德。
