Then the MEMS solenoid type electromagnetic actuating and novel, frictionless and wear-free, and simple structure are designed for fiber-deflecting type MEMS VOA: One of the two coupled single mode fibers is completely fastened in one of the three aligned U-shaped grooves while the deflectable fiber is partially fixed in another groove with a long front section suspending over the wider groove as a cantilever beam. The two fibers, any one for input and the other for output, are well aligned initially so that the insertion loss is very low. Beside the deflectable fiber is a solenoid microactuator with a U-shaped permalloy core attracting a permalloy piece glued on side of the fiber cantilever so that the fiber is deflected and the optical power coupled between the fibers decreased continuously. Using MEMS solenoid as a continuous actuator and the novel structure of VOA are not seen in literature.

In the low B condition of the soilless culture, rapeseed seedlings were short of B, the seedlings were short and the leaves were malformed and the weight of the shoots decreased, the branch roots were fewer and snuff color, the weight of roots decreased, and the length of root and the ratio of shoot/root decreased, too. However, the high B- efficiency type of rapeseed had the a great ability to the low B stress, the growth of shoots and roots were better than the low efficiency, and the B concentration range of the rapeseed varieties which responded to the B scarce was 0.001 mg/L to 0.01 mg/L.

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.

As the forward velocity increasing, the windrowing angle would be decreased, but the effect of forward velocity on windrowing distance was not obvious. The windrowing angle and distance of multiple sugarcane stalks would be smaller than those of single sugarcane stalk, but the maximum range of windrowing angle and distance of multiple sugarcane stalks would be greater than those of single sugarcane stalk. In order to sugarcane stalks outward windrowing, holding height must be within ±100mm of height of sugarcane mass center. As holding height increasing, the windrowing distance would be decreased, but the effect of holding height on windrowing angle was not obvious.
随着夹持输送装置输送速度的增大,甘蔗铺放角和甘蔗铺放距离也随着增大,随着机车前进速度的增大,甘蔗铺放角是减小的,而前进速度对甘蔗的铺放距离影响不大;多根甘蔗的铺放角和铺放距离要比单根甘蔗小,铺放角和铺放距离最大极差要比单根甘蔗大;入口夹持点高度应在甘蔗质心高度±100mm范围内为宜,以保证甘蔗能向机车外侧铺放,随夹持高度的增加,甘蔗质心位于夹持点下方的距离增大,甘蔗铺放距离减小,而夹持高度对甘蔗铺放角影响不大。
