Instead, the erosion resistance is increased after FSP. The refined and uniformly distributed second phases, which are resulted from the FSP, can help to increase the hardness and further reduce the brittle fracture of the specimens. Si and nvAl3CuNi phases are usually found near or end of the grooves with little fracture. But the τ1 (Al9FeNi) phase is easier to be removed by the erodent cutting. It can be inferred that Si and nvAl3CuNi are useful to improve the erosion resistance of A384 aluminum alloy, but τ1 (Al9FeNi) phase is detrimental for the erosion resistance of A384 aluminum alloy.

经摩擦搅拌制程改质后，硬度提升，晶出相细化且均匀分布，降低脆性龟裂的现象发生，有助於改善A384铝合金的磨耗性质，其中，亦发现在冲蚀沟槽附近有残留和脆性破裂之共晶Si颗粒和nvAl3CuNiw晶出相，推测此两相为A384铝合金中有助提升磨耗阻抗的第二相；而τ1(Al9FeNi)晶出相则容易受到冲蚀颗粒的切削而被冲蚀颗粒移除，增加材料的重量损失，推测τ1(Al9FeNi)晶出相为A384铝合金中较不耐磨耗的晶出相。

Recent data have provided clear insights into some aspects of self-recognition and rejection in the SI response of three types,the single-locus sporophytic and two distinct forms of single-locus gametophytic SI.

高等植物在长期的进化过程中，通过雌蕊识别并拒绝遗传上相近的花粉，防止近亲繁殖、保持遗传多样性，该机制被称为植物自交不亲和性。

The nc-Si/c-Si heterojunction MAGFET manufactured by CMOS process owns inequipotential potentials VHO, which increases with increasing absolute value of supply voltage VDS.

摘 要：采用CMOS工艺制作的纳米硅/单晶硅异质结MAGFET存在不等位电势VHO，不等位电势VHO随工作电压VDS绝对值增加而增大。

The experiment result shows, when extra magnetic field B=0, and supply voltage VDS is constant, inequipotential potentials VHO of the nc-Si/c-Si heterojunction MAGFET are close to zero output with increasing absolute value of the gate biased voltage VGS. Adopting gate biased voltage to compensate inequipotential potentials, compared with extra compensation resistance method, could improve magnetic sensor sensitivity, when supply voltage VDS is -1.0 V, magnetic sensitivity can be improved by 18%.
