先导的

Then, have described the current situation of industry"s development of guide of our country and summarized the industrial policythat such countries as U.S.A., Japan ,etc. develop the high-tech industry, from the industrial structure policy, industrial organization policy , industry technological policy and industry overall arrangement policy four respect put foi"ward in an all-round way building well-off society period of our country guide industrial police of industry.

继而，描述了我国先导产业发展的现状，总结美国、日本等国发展高技术产业的产业政策，从产业结构政策、产业组织政策、产业技术政策和产业布局政策四方面提出了全面建设小康社会时期我国先导产业的产业政策。

In this paper the induced charge distribution on a spherical petroleum tank due to lightning is calcuated with analytical method,and that on a cylindrical petroleum tank is calculated with charge simulation method.

文摘：本文用解析法计算了雷电先导在球形贮油罐上的感应电荷分布，用模拟电荷法计算了雷电先导在圆柱形罐上的感应电荷分布；并对圆柱形罐上架设的避雷针的保护特性进行了计算校核和实验校核。

In the striking distance factor model, randomicity of progression for up leader and down leader is ignored, and the critical striking electric intensity of lightning leader to phase conductor and ground are both decided to 500kV/m. This suppose is not proper.

击距系数模型忽略了上下行先导发展的实质，将先导对地与对导线的临界击穿强度均取为500kV/m，这种假设不合理。

Results show that load change has evident effect on pressure and flow rate of operation orifice of pilot valve, and pressure value of operation orifice should fluctuate in a biggish range as design pilot valve.

分析表明，负载的变化对先导阀的出口压力和流量影响较大，设计先导阀时，工作口压力的波动值应在一个较大的范围内综合考虑。

Since various rocks, complex structure and steep strata in the site, integrated well and ground seismic explorations were adopted on the two pilot holes, and 3D reverse VSP layout was used in microlog data acquiring.

由于工区岩石类型多样、地质构造复杂、地层倾角大，围绕预先导孔和先导孔所进行的两次地震数据采集均采用了井地联合的观测方法，微测井则是按照三维逆VSP的观测方式进行的。

Each place a lightning bolt zigs or zags is where one leader stopped and another one started.

闪电蜿蜒的地方就是先导区停止而同时另一先导区形成的地方。

Distribution of Direct Drive Type Solenoid Valve The distribution of direct-action solenoid valve works: it is a direct-acting and pilot-style combination of theory, when the entrances and exits when there is no differential pressure, electricity, the electromagnetic force directly to the pilot valve and main valve off small pieces turn up raised, the valve opens.

分布直动式电磁阀分布直动式电磁阀的工作原理：它是一种直动和先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，阀门打开。

Distribution of Direct Drive Type Solenoid Valve The distribution of direct-action solenoid valve works: it is a direct-acting and pilot-style combination of theory, when the entrances and exits when there is no differential pressure,气动阀, electricity, the electromagnetic force directly to the pilot valve and main valve off small pieces turn up raised, the valve opens.

分布直动式电磁阀分布直动式电磁阀的工作原理：它是一种直动和先导式相结合的原理，当入口与出口没有压差时，通电后，电磁力直接把先导小阀和主阀关闭件依次向上提起，排气阀，阀门打开。

In this manner, the negative charge hops downward from leader to leader like a frog jumping from lily pad to lily pad across a pond.

而负电荷就是以这样的先导区至先导区的方式，如同青蛙从一朵睡莲叶子跳至另一朵睡莲叶子越过池塘，到达地面。

In order to find screening rules suitable for lead compounds of pesticide,five descriptors:logarithm of partition coefficient of octanol/water,relative molar weight,number of hydrogen-bond donors,number of hydrogen-bond acceptors,polar surface areaand carcinogenic and mutagenic toxicities of 242 fungicides,512 herbicides and 399 insecticides were calculated and analyzed.

为了寻找适合于农药的先导筛选规则，对242个杀菌剂、512个除草剂和399个杀虫剂的5个描述符：疏水常数、相对分子质量、氢键给体数、氢键受体数、分子极性表面积和毒性进行了计算和分析，提出了杀菌剂、除草剂和杀虫剂先导化合物的筛选规则。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
