all individuals were focused on two zones at the third principle axis ( z-axis ), which showed the distribution of soluble salt in soil y軸為第二主分量,從y軸上個體的投射點的分布梯度來看,基本上反映了經(jīng)度變化的趨勢。
combined with the actual developing situation, a new design is originated, that is, non-contact torque measurement through grating sensor . this paper has also presented the study of whole measurement system . according to actual experimental condition, a new torque measurement system of water turbine's principle axis is designed and tapped 文章結(jié)合扭矩測量的國內(nèi)外發(fā)展現(xiàn)狀和實際,根據(jù)國家自然科學(xué)基金資助項目“水輪機(jī)主軸機(jī)械系統(tǒng)動態(tài)特性研究”提出的方案,采用光柵式傳感器進(jìn)行扭矩的非接觸式測量,并對其整個測量系統(tǒng)進(jìn)行了研究。
at the first principle axis ( x-axis ), 98 individuals concentrated on four region : subp . 1 was mainly distributed at-2-1 range, subp . 2 at-1-0, subp . 3 and subp . 4 at 0-1, subp . 5 at 1-3 . it revealed the distribution of the individuals related to the soil water and nutrition . and similarly, p . sibirica individuals scatter at the second principle axis ( y-axis ), which representing the altitude and latitude x軸為第一主分量,98個個體的投射點分別集中在四個區(qū)間在一2~一1區(qū)間以亞居群1為主,一1~0區(qū)間以亞居群2為主,o一1區(qū)間以亞居群3、4為主,1~3區(qū)間以亞居群5為主。
