It was observed that the influence of bud and its position on the healing process of grafting unions using hardwood sectioning method, and found that:(1) bud of a scion and its position to the graft unions have no influence on callusing formation of the isolation layers, and the early differentiation of cambia;(2) a scion bud closer to the grafting union would promote the formation of more compacted callus cells and the earlier formation of callus bridges;(3) conduit differentiation in grafting unions of lower-bud scions was later than that of other treatments.

利用滑动切片法对芽子有无及芽位对嫁接愈合过程的影响进行了观察，发现：(1)接芽有无及芽位对隔离层及愈伤组织形成和形成层的早期分化没有影响；(2)芽或去芽的芽位距接口近，可以促进愈伤组织的紧密连接，即愈伤组织桥的形成；(3)低位芽枝嫁接体中导管分化较晚，而其它处理导管的分化几乎是同时发生的，而且导管首先出现于愈伤组织薄壁细胞中。

It analyses the characterization of typical type curve and the influential factor of well-test curve ,which includes non-dimensional offsetting, non-dimensional length of horizontal welk equivalency pressure point, interporosity flow coefficient, storativity ratio and the boundary condition.

分析了双重介质水平井典型曲线特征以及影响水平井试井曲线特征的因素，得到了其影响因素主要有无因次偏心距、无因次水平井长度、等价压力点、储能系数、窜流系数以及油藏的边界条件。

Results There was a downtrend in weight of dams on GD20 as the DBTD exposure dose increased. The weight of dam's utero significantly decreased in 30 mg/kg group. A significant decrease in fetal weights was observed in all DBTD groups, and fetal sizes in 20, 30 mg/kg groups. Exposure to DBTD from GD 12-19 resulted in a distinct increase in normalized anogenital distances in female fetuses, but no effects were seen in male ones.

结果 妊娠20d时，孕鼠体重随DBTD剂量升高呈下降趋势，但与对照组比较，差异无统计学意义，30mg/kg组孕鼠子宫重量显著降低；所有DBTD染毒组雄性、雌性胎鼠体重均显著降低，20、30m/kg组胎鼠体长显著降低；所有DBTB染毒组雌性胎鼠肛门距生殖器的标化距离显著增长，而雄性胎鼠无显著变化。

In this paper, the research of the non-ripple torque control system of brushless motor is an emphasis.

Taking cydid gear-pin rail chainless traction mechanism of MG375W as an example, make theoretical deduction for the profile and the kinematic characteristics of the cycloid gear , and make simulation analysis for some different engaging positions by computer.

以MG375W采煤机的摆线轮与销排无链牵引机构为例，进行了摆线轮齿廓特性及运动特性的理论推导，对不同的啮合工位进行了计算机模拟仿真分析，得出了中心距及节距发生变化引起啮合传动特性的变化规律。

However, the soil moisture content at soil depths of 45 cm and 60 cm in the areas with microbiotic crusts is much lower than that in the areas without microbiotic crusts (LSD-test, p.05), which reveals that the microbiotic crusts have high capability of maintaining topsoil moisture.

结皮覆盖区距地表5cm和10cm处的土壤含水量显著高于无结皮覆盖区（LSD检验，P.05）；而45cm和60cm处的土壤含水量则表现为结皮覆盖区极显著低于无结皮区（LSD检验，p.05），说明生物结皮具有较强的保持土壤表层水分的能力。

METHODS: Constructing the CAM model by exposing CAM on the shell subpoint between 2 vitelline veins and generating an air chamber after 5 days of incubated with aseptic incubator at 37℃.

将鸡胚消毒后，置于37℃无菌恒温箱中孵育5 d，在距胚头1 cm两条卵黄静脉之间的卵壳投影部位磨切暴露尿囊膜，制成假气室，用无菌滤纸封闭窗口，制成鸡胚尿囊膜模型，备用。

Before transecting inject 1ml Sodium Chloride in the epineurium. Annular tensile the proximal of epineurium with microscopic forceps annular shear the epineurium 7mm before broken ends with microscopic shear and stretch the epineurium until the two ends distance is 5mm.Use 8-0 suture line to bridge the nerve gap and make a 5 mm nerve tube at the proximal nerve end. Interrupted suture the epineurium tube and the distal nerve end make a 5 mm nerve mamuro for the injury nerve.Results: Postperative observation lasted for 6 weeks regeneration nerve through the 5 mm nerve mamuro.

在大鼠的坐骨神经距股方肌下缘15mm处，用1ml注射器向神经外膜下注入1ml生理盐水，然后于此处切断坐骨神经，用显微镊环形拉伸近端神经外膜，在距断端约7mm处用显微剪环形剪开神经外膜，并继续拉伸外膜使外膜两断端间距约5mm停止，用8-0的无损伤缝线桥接神经外膜两端，在神经近端形成约5mm的神经外膜管，将神经外膜管与神经远端间断缝合，使断伤的神经束间留有5mm的小间室。

We can produce any different pitch blade according to customer needs, the classic value of the pitch: A, 10 degree, suitable brush motor FP helichoper, let lower speeds rotor greater lift; B, 8 degree, suitable brushless motor FP helichoper, can make the main rotor get a higher speed; C, 6.5 degrees, suitable some DIY FP helichoper, can make the helicopter have better lock tail performance with a small diameter and high-speed tail rotor.

桨距可以根据客户需要进行定制，经典的桨距值为：A、10度，适合有刷马达的FP电直，能够在较低的转速下取得更大的升力；B、8度，适合无刷马达的FP电直，能够使主桨获得更高的转速；C、6.5度，适合玩家DIY的FP电直，配合小直径高转速的尾桨，能够获得更好的锁尾表现。
