Through the preliminary study on the management of the population of Athyrium multidentatum, we found that the community of artificial Larix gmelinii forest has a high value of usage. Planting the population of Athyrium multidentatum may make us to improve the level of intensive management, and through the test this method is available. The population of the spacing in the row of forty cm in the community of Betulla platyphylla forest and the population of the spacing in the row of eighty cm in the community of artificial Larix gmelinii forest have the largest hight, leafstalk diameter and less herb coverage. The foodstuff technology of ferns is backward and the products are less, so we must improve the study on the usage of forest ferns.

通过对猴腿蹄盖蕨种群经营措施的初步研究，我们得出落叶松人工林群落是一个极具开发价值的群落；人工移栽猴蹄盖蕨种群，可提高集约化管理程度，经过试验，方法可行；白桦林群落株距40cm的猴腿蹄盖蕨种群高度、叶柄直径均最大，且杂草盖度较小；落叶松人工林群落株距80cm的猴腿蹄盖蕨种群高度、叶柄直径均最大；蕨菜食品加工技术落后、工艺简单、产品单一，今后应加强研究。

Besides, we found that a 1 cm thick Lucite screen at 10 cm from the patient was enough to build up the surface dose.

至於表面剂量则可用1公分压克力屏风置於病人前方10公分以达到足够的治疗剂量。

Leaflets 2.5--5 cm wide, abaxially densely whitish brown maculate, margin crisp when dry; sepals of male flowers 1--1.5 cm

小叶2.5 --5厘米宽，具斑点的背面浓密带白色棕色，边缘干燥时脆；雄花的萼片1 --1.5厘米 7 S。

To exam the validity of the Bloch-Grüneisen formula at megabar pressures, we use the electrical conductivity data point of ε-iron at relatively low pressure (～40GPa) reported by Keeler as a reference point, a formula for calculating the conductivity of the ε-iron under high-pressure and temperature was deduced via Bloch-Grüneisen,where v is specific volume , T is temperature and σ is electrical conductivity .

为了检验Bloch-Grüneisen公式在兆巴压力冲击压缩下的有效性，本文取Keeler在较低压力下ε相区的一个电导率数据作为参考点，得到了Bloch-Grüneisen公式关于ε-铁在高温高压下电导率的一个解析表达式：σ=〓，这里，比容v的单位是cm〓/g，温度T的单位是K，电导率σ的单位是Ω〓cm〓。

Inflorescence 20-35 cm; staminodes 3 or 4; drupe 5-10 cm, mesocarp fleshy, endocarp flattened.

花序20-35厘米；退化雄蕊3或4；核果5-10厘米，中果皮肉质，扁平。 1 M。 indica 杧果

Diffusion coefficients for metol and p-benzenediol were 2.1×10 cm^2/s and 2.7×10^6 cm^2/s, respectively. The electrocatalysis mechanism has been studied. ATR-FTIR was used for the characterization of the ME/Au SAMs. The oxidation currents were linear in the range of 1.0×10^(-7)~1.0×10^(-4)mol/L for metol and 6.0×10^(-6)~6.0×10^(-4)mol/L for p-benzenediol, with the correlation coefficients of 0. 9992 and 0.9996 by differential pulse voltammetry, and detection limit 2.0×10^(-8)mol/L and 1.2×10^(-6) mol/L for metol and p-benzenediol, respectively.

采用水平衰减全反射－傅立叶变换红外光谱技术对ME/Au SAMs进行了表征，示差脉冲伏安法同时测定米吐尔和对苯二酚，不产生干扰，其氧化峰电流与相应物质的浓度分别在1.0×10^(-7)~1.0×10^(-4)mol/L和6.0×10^(-6)~6.0×10^(-4)mol/L范围内呈良好的线性关系，相关系数分别为0.9992和0.9996，检测限分别为2.0×10^(-8)和1.2×10^(-6)mol/L。

Calyx 8-9 mm; leaf blade 3-6 cm wide, lateral veins 8-12 on each side of midrib; capsule 4-4.5 cm.

花萼8-9毫米；叶片3-6厘米宽，侧脉8-12在中脉每边各；蒴果4-4.5 厘米 8 R。

In all fertilization treatments, the mean mass diameter of WSAs was larger in 0-10 cm than in 10-20 cm soil layer. Compared with non-fertilization, long-term fertilization increased the MMD of WSAs, and organic manure was superior to chemical fertilizers.

各处理0~10cm土壤水稳性团聚体平均质量直径均大于10~20cm土层；自然土壤的团聚体MMD显著高于同层次耕作土壤，长期施肥处理MMD大于无肥对照，有机物质培肥处理明显高于化肥处理。

Carposina, Navicula caterpillars, flat postornata, soil pests such as mole cricket, can they turn to land the ground froze to death;also bollworm damage, stick insects, sawfly wheat, locust pupae Room nests, etc., to prevent its emergence or incubation in order to better carry out Overwintering insects buried in the 10 ~ 15 cm layer, it should be frozen in the soil before or early spring, while the pests,"sleep" when the Land20 ~ 30 cm, so that exposure of adults or pupae on the ground was frozen to death or birds pecking; such loose soil can also help the soil ripening, and enhance the permeability of soil.

害虫越冬入土在10～15厘米层间，故应在土壤封冻之前或早春，趁害虫"熟睡"之际，将田土深翻20～30厘米，使成虫或蛹暴露在地面上被冻死或被禽鸟啄食；这样也可使土壤疏松，有利于土壤的熟化，增强土壤通透性。

Scintillator strips are 1 cm thick, 4.1 cm wide, and their Moliere radius is of 3.7cm.

闪烁带1厘米厚， 4.1公分宽，其半径是莫里哀的三点七厘米。
