The method solves the problems better through adopting the following technical proposal that: the method takes the solid super acid consisting of the VIB group elements or the VIB group elements and the IVB group elements in the periodic table of elements and loaded on a symbiosis molecular sieve as catalyst, and naphtha with the component being C4-C10 as a raw material so as to carry out catalytic cracking reaction at a temperature of between 550 and 700 DEG C, under a pressure of between 0.01 and 0.5 MPa, at a reaction weight space velocity of between 0.1 and 4 hours and with the weight ratio between water and naphtha of between 0.5:1 and 4:1, thereby generating ethylene and propylene.

本发明涉及一种催化裂解制乙烯丙烯的方法，主要解决现有催化裂解制乙烯丙烯催化剂的使用温度高，活性低，乙烯丙烯选择性差的问题，本发明通过使用在共生分子筛上负载由元素周期表VIB族元素或VIB族元素和IVB族元素组成的固体超强酸作为催化剂，以组份为C 4 ～C 10 的石脑油为原料，在反应温度为550～700℃，反应压力为0.01～0.5MPa，反应重量空速为0.1～4小时-1 ，水/石脑油重量比为0.5～4∶1的条件下，进行催化裂解反应生成乙烯丙烯的技术方案，较好地解决了该问题，可用于催化裂解制乙烯丙烯的工业生产中。

Results In pre-school children, tibial and radialis bone strength of obese group was worse than normal weight group, and the descending risk of bone strength in obese group was 6.87 and 2.24 times of normal children. Bone strength was not different in overweight and normal weight groups.

结果 学龄前肥胖儿童胫、桡骨骨强度均低于正常儿童，胫、桡骨骨强度下降风险分别是正常儿童的6.87倍和2.24倍；超重组与正常组无差别。

On the basis of analyzing the theory of the modeling of the propeller surface, this paper transforms the section data given by design to the data in Descartes coordinates. Interpolates the section data to get enough data and fits the blade surface with the least square method. A perfect C2 blade surface can be obtained by adjusting the deviation weight and fairing weight. According to the cylinder rough, two rough cut methods are preferred.

本论文在深入分析螺旋桨曲面成型原理的基础上，将设计时给定的桨叶曲面的切面数据转化为笛卡尔坐标系中的坐标，利用B样条方法对截面数据点插值并加密，得到足够的数据点，进而利用最小二乘法拟合出桨叶曲面，通过调整偏离权和光顺权得到了理想的二阶连续的桨叶曲面。
