级长

Based on the rigorous coupled wave theory,the phenomenon that the zero order reflection efficiency of rectangular subwavelength grating varies with the wavelength is studied when incidence angle,azimuth and grating parameters are variant.

从严格耦合波衍射理论出发，在不同入射角、方位角和光栅参数下的情况，计算了矩形亚波长光栅零级反射效率随入射光波长的变化。

On the basis of the theoretical analysis and research, the refractivity measurement system was designed, which was based on cascade LPG and phase generated carrier technique. The feasibility of system was in detail demonstrated.

在理论分析研究的基础上，设计了基于级联长周期光纤光栅的、采用相位生成载波技术对被测量信号进行解调的折射率测量系统，并对系统的可行性进行了较为详细的论证。

All three solid-fueled rocket stages of the vehicle have finished qualification testing.

第四级因承担下面级的姿态控制和保证最终入轨精度，技术含量高，发费的时间长些，明年能准时试射吧。

In addition, oil fields at sea frequently require installation work, which is why the 3,000 short ton crane was developed. With its 90-meter jib, a 100-ton hoisting block, a total crane weight of over 2,200 tons and its height of over 75 meters, this crane is truly a 'big guy', even by Huisman standards.

另外，海底油田常常需要进行安装工作，这也是开发3000短吨级起重机的原因。90米长的起重悬臂，100吨中的起重滑轮，全重超过2200吨，高度超过75米，即便按照豪氏威马的标准，这台起重机也是一个真正的"大家伙"。

A method for protecting channel error code resistance ability of low speed vocoder includes applying improved Chinese plain code and BCH code to separately protect voice parameter in voiceless and voiced sound frames at coding end, using BCH code to recover relevant parameters of voiceless sound frame and using maximum post verification probability rule to recover parameter of voiceless sound accurately for voiced sound frame then using line spectrum to parameter anti-error code algorithm to recover line spectrum to parameter at decoding end.

该方法在编码端改变2.4kb/s SELP编码后清音帧清浊音参数的发送模式；采用BCH码和改进的(7，4)汉明码分别保护清音和浊音帧中的语音参数；在解码端，根据信源信道的联合特性采用分支判决确定清浊音；对于清音帧采用相应BCH码恢复出对应参数，对于浊音帧采用基于长时统计特性的最大后验概率准则恢复清浊音参数，并解码出线谱对参数第一级并对残留误码的线谱对参数采用线谱对参数抗误码算法恢复。

For the double purpose of practicability and fashion, LF320 is designed as a compact car with five doors. The dimension is 3755*1624*1435mm and the minimum ground clearance is 135mm which makes good trafficability. In addition, the wheel base of 2340mm makes it have unparalleled room among its peers.

为兼顾实用性和时尚性，设计师们将LF320设计为五门掀背紧凑型轿车，长宽高分别为3755*1624*1435，最小离地间隙为135mm，具有良好的通过性能。2340mm的轴距让其在AO级车型中拥有无可比拟的空间优势。

Long can bring to exit to window-shop, the body and mind all healthy average person line, after all I am not "the loose talented person" the rank.

长的能带出去逛街，身心都健康的一般人就行，毕竟我也不是什么"风流才子"级别的。

The sludge in SBMBR1 presented granular characteristics and settled very well. The sludge in SBMBR1was brown and the sludge flocs was smashed by the shear force due to high intensity of aeration. The sludge size decreased and the sludge flocs blended with water forming ropy solutions, and there was no distinguish interface between water and sludge. Low sludge age and high loading operation enabled the sludge in SBMBR1 keeping higher sludge activity and the MLVSS/MLSS ratio and SOUR values of SBMBR1 were higher than SBMBR2. Both in SBMBR1 and SBMBR2, there were large amount of zoogloea, bacillus, coryneform of bacteria, and pediococcus. However, in SBMBR1 there were also a lot of Protozoa like epistylis and etc. A certain amount of filamentous bacteria can also be found in SBMBR1. The biological species in SBMBR1 were much more abundant than that in SBMBR2.3. Membrane fouling on flat-sheets membrane was observed and analyzed with AFM, SEM and TEM. After the measurement of membrane surface EPS and membrane surface ETX analysis, the pollutants composition on the surface of flat-sheets membrane was calculated.

从外观观察SBMBR1反应器中的活性污泥呈浅黄色，随着运行时间的增加，污泥粒径逐步增加，SV、SVI值逐步下降，呈现出较强的颗粒特征，沉降性能良好；SBMBR2污泥呈土黄色，污泥絮体被高强度的曝气所产生的切应力所打碎，污泥粒径迅速降低，絮体较为细碎，和水相混合成均一粘稠的溶液，看不到泥水分界面；低泥龄、高负荷运行，使得SBMBR1可以保持较高的微生物活性，MLVSS/MLSS值、SOUR值均高于SBMBR2；两级反应器活性污泥中均有大量的菌胶团，长杆菌、短杆菌和球菌是构成主体，但SBMBR1活性污泥中含有大量固着型原生动物如累枝虫等，还存在着一定数量的丝状菌，生物相要比SBMBR2丰富。3、借助原子力显微镜、扫描电镜、透射电镜等手段对平板膜污染现象进行观测和分析，并通过膜表面污染物EPS测定、污染膜表面能谱分析，得出平板膜表面污染物的组成。

"Fronts," as they're affectionally called, are by far the most popular tanganyikan cichlid.

皇冠六间号称坦湖之王，展示级的六间可以达到12英寸长，它被呢称为&Fronts&。

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。
