Special mouth shape + sawtooth salmon-like cut teeth, This also explains why this strange dog, which has always been small, can bite nearly two-thirds of the muscles (watermelon size) of an adult male thigh. Even if it is a small watermelon, if you are interested, you can buy one and put it on your thigh to gesticulate to see how much the volume has reached the total thigh muscle) and tear it off.敬文娘道：可不是么。1944年年底，在樊庆笙教授等人的努力下，中国生产出了第一批5万单位／瓶的盘尼西林，俗称“青霉素”，成为世界上率先制造出盘尼西林的七个国家之一。中共上海地下党很快得到了青霉素的菌种和配方，并利用中山医院实验室主任齐小云的身份和实验室的有利条件秘密试验和生产青霉素。第一次青霉素样本试制出来后，由医院神经外科主任陈慧琳的未婚夫、上海麻醉协会秘书长邓红负责送出敌占区。然而，由于叛徒出卖，邓红暴露了。为了保证青霉素秘密不被日本人发现，邓红毅然将青霉素样本吃进了自己的肚子，玻璃划破了他的喉咙，对青霉素过敏的他，因青霉素过敏而死亡。正等着进入婚礼殿堂的陈慧琳面对邓红的尸体，不甘心，不理解。为了弄清真相，她固执地去给邓红做尸检。此料，她这一尸检，彻底暴露了共产党在中山医院秘密试验青霉素的秘密。这个秘密马上就被日军参谋本部获知。为了掠夺到这在当时还很稀缺药品的专利，日本人在东条英玑的亲自过问下制定了一个青梅计划，计划的实质内容就是要不择手段地从中国获取青霉素的配方和菌种。国民党政府为了巩固自己对青霉素的It is convenient for fighting and evacuation, and a circular fire lane should be set up. With the accelerating pace of urbanization, urban land is increasingly tight, which promotes the construction of high-rise buildings. Many high-rise buildings, due to poor consideration of fire prevention design and other reasons, have many congenital hidden dangers, and fires occur from time to time, causing heavy losses. In order to create convenient conditions for fire fighting and rescue work and ensure the safety of buildings, circular fire lanes should be set up around high-rise buildings. However, regardless of the size of the building, it is indeed difficult to require the circular fire lanes. Lanes can be set up along the two long sides of the building. In order to prevent the collapse of building components in case of fire from affecting the normal operation of the fire lane, the distance between the fire lane and the outer wall should be 5m. There should be no trees, overhead pipelines, etc. that hinder the operation of climbing fire engines between fire lanes and high-rise buildings. If the total length of the building exceeds 220m, a fire lane shall be set up to pass through the building. There is no inner courtyard in the building, there are ring fire lanes around it, and fire engines crossing the building need to be set up. Q: An L-shaped high-rise building has a total length of about 170m, a length of 120m along the street, and a length of 50m along the inner street (residential road). Do you want to set up fire lanes crossing the building? A: The relevant provisions of the "Construction Regulations" and "High Regulations" consider that there is no restriction on the length of the two wings on the premise of meeting the requirements of fire fighting and evacuation. The building only needs to set up a pedestrian passageway connecting the street and the inner courtyard at the part over 80m along the street, and there is no need to set up a fire lane. In the planning of fire lanes, in addition to the relevant provisions of the "Construction Regulations" and "High Regulations", attention should also be paid to
