These results is helpful to the institution of fired perforated brick masonry code of Chong Qing. And it is benefit to the popularization of perforated brick. Analysis of experimental result has show 4 points below.① Shear strength of perforated brick masonry is composed of mortar cohesive strength and pin keys shear strength.

试验结果分析表明：①多孔砖砌体的抗剪能力由砂浆粘结抗剪和砂浆销键抗剪两部分组成，由于砂浆销键的存在，多孔砖砌体的通缝抗剪强度较实心砖砌体有较大幅度的提高。

The national defence basic project as background and the dynamic model of cotrolled transfer matrix for multiple launch rocket was created in order to reduce the initial disturbance of rocket projectile. The causes that affect the angle change of orientation locator were analyzed by the engineering system dynamic theory base on multibody system transfer matrix method. The simulation of dispersion for multiple launch rocket was implementation, and the affect law between the angle of elevation and side deflection and the control parameters was acquired. The control module was installed on the orientation locator of multiple rocket launcher to control the initial disturbance of rocket that provide new method and theory base and show the engineering system dynamic base on the multibody system transfer matrix method is effective.

本文以国防基础科研项目为背景，建立了通过控制定向器角运动来减小火箭弹起始扰动的多管火箭受控多体系统动力学模型，应用基于多体系统传递矩阵法的工程系统动力学理论，进行了定向器角度运动的影响因素分析，进行了受控多管火箭炮发射动力学和密集度数值仿真，得到了定向器俯仰和侧偏角控制参数对俯仰角和侧偏角的影响规律，为在火箭炮定向器上加装控制集成模块控制火箭弹的起始扰动和射击精度提供了新思路和理论基础，也表明了基于多体系统传递矩阵法的工程系统动力学理论的有效性。

A mig (mannose insensitive germination) mutantpool, which was created with T-DNA insertion by Kenneth Feldmann, University ofArizona (ecotype Wassilewskija-2, Ws-2), was obtained from the Nottingham ArabidopsisStock Centre, UK. mig3 is one line of the mutant pool, which was thought as aputative mutant for having a high germination rate (about 70%) on MS media containingabout 5-7.5 mM mannose. Lately, the mig3 was found there are some special characteristicsin two French labs by Laurent Signore and Marlire Dieuaide.

本文作者就是以这一突变体为研究对象，开展了有关控制mig3突变体的基因的定位研究研究；并同时开展了在几种糖及其衍生物诱导下的光合作用有关基因表达的研究；这一突变体在开花前后几种糖分含量的调查；开花习性及形态方面的调查。

Because slack has changed the underground water condition which led to the gathering of underground water at the mudstone cleavage zone, and has decreased the resistance, of which the synthetic 〓 is about 13°, it has made the rock mass about the cleavage slide slsde in the western direction.

从边坡岩体地质力学调查分析、岩体结构分析和采煤对滑坡的影响分析，得出滑坡形成的机理，采煤使P〓岩层中沿NW10°~20°/W15°劈理带贯通而移动，由于松弛改变了地下水条件，使地下水向之集中，该泥质劈理带在过水下摩阻力降低，其综合φ为13°左右，使上覆岩体沿之向西滑动。

The present invention relates to a nano-bullet-proof tires made of solid environmental protection methods, specifically the use of a nano-materials, renewable sources of rubber, rubber material dispensed through a series of processing, made of "nano-rubber in solid matrix""Matrix" outside "bullet-proof body", through the composite adhesive, bonding, in a plastic bag,"Nano polyurethane tread", made of "nano-bullet-proof tires solid environmental protection."

本发明涉及一种纳米防弹环保实心轮胎的制成方法，具体讲是一种利用纳米材料、再生橡胶、橡胶料的配发，经过一系列的加工，制成"纳米橡胶实心内胎体"，在"内胎体"外设置"防弹体"，通过胶粘剂的复合、粘接，在包胶一层"纳米聚氨酯胎面"，制成"纳米防弹环保实心轮胎"。

Heat transfer between ingot and mold is then intensified by the quickened flow velocity of Al melt. As a result, the initial solidifying point on the ingot surface in mold moves upwards to decrease the height of contact zone between the melt and mold so as to improve the surface quality of ingot.

铝熔体流动速度的加快能增强石墨环与铝熔体之间的换热，使结晶器内铸锭表面初始凝壳点位置上移，减小了铝熔体与结晶器的有效接触高度，提高了铸锭的表面质量。

These observations suggested that FoxD5 dose not take parts in the cyclic pre-pattern of the PSM, but involves in the process of somite formation.

这些结果显示FoxD5并不影响体节之周期性形成，而是藉由调节体节生成之过程而参与在体节之发育。

The morphological observation has identified 37 mutant lines, the majority ofwhich showed anomalies in axis and somite formation. Ten of them are kept forfurther study.

表型观察法筛选了约 200 个 F2 家族，获得了 37 个突变品系，其中以体轴和体节发育异常的突变体为主，将其中 10 个品系保种，以备进一步研究。

Chapter Ⅱ Xenopus Tbx6 Mediates Presomatic Mesoderm Cell Adhesion during Somitogenesis As a member of T-box gene family, Tbx6 is involved in somite cell fate decision and endows adhesion properties to mesoderm cells.

第二章 xTbx6在体节发生过程中介导了预定体节中胚层的粘连 xTbx6是T-box转录调控因子家族的成员，xTbx6参与体节细胞命运决定和赋予旁侧中胚层细胞特定的粘连特性。

When the finishing temperature is 950℃ and the cooling rate is 4℃/s, the interlamellar spacings of pearlite is a bout 97 nm and the percentage of sorbite is 95.7%. At this time, the structure is the best.

高碳钢SWRH77B在终轧温度为950℃、冷却速度约为4℃/s时，其珠光体的片层间距约为97nm，索氏体含量达到95.7%左右，表明此时的组织为最佳索氏体组织。

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.
