  • b :
  1. Based upon the comparison of cyto b gene sequences in 15 deer species downloaded from genbank, a universal primer set l15774 / hsf21 was used as positive control of the template quality, at the meantime, two species specific primer sets df / dr and cf / cr were desgined to identify red deer ( cervus elaphus ), sika deer ( cervus nippori ) and roe deer ( capreolus capreolus ) from other species. a musk deer ( moschus ) specific primer set wf / mr was designed, siberian musk deer ( afoschus moschiferns ) and forest musk desr ( moschus berezovskii ) could be discriminated when restriction endonuclease rsa i was used to cut the pcr products

    經過對來自genbank中的15種鹿類動物的cytob基因序列的比較,用通用引物l15774和hsf21作為模板的質量控制,設計了特異性引物df dr和cf cr來鑒定馬鹿、梅花鹿、狍;設計了麝類特異性引物mf mr ,用限制性內切酶rsa酶切擴增產物來區分原麝和林麝。
  2. We also report the uv - visible optical absorption spectra of these colloids. to the metal plate prepared simultaneously, the measurement result of sem and afm of this plate is also reported and the roughness of the silver plate surface is about 60nm. both the colloids and the nano - scale metal surface can become the very perfect sers substrates. rhodamine b, a kind of strong fluorescence laser dye, with gold colloidal surface, has been studied by surface - enhanced raman spectroscopy ( sers ) with near - infrared ( nir ) excitation in the presence of the halide ions ( cf, br -, f )

    利用透射電子顯微鏡( tem ) ,對膠體粒子的尺寸大小及形態進行了觀測,表明這些膠體為粒徑介於5 35nm的納米體系,並對該膠體體系進行了紫外?可見吸收光譜的研究;在制備出金屬膠體的同時,經過激光照射后的金屬表面為納米量級的粗糙表面,對該表面進行了掃描電鏡( sem )及原子力顯微鏡( afm )的測量,結果顯示該表面的粗糙度平均為60nm 。
  3. 3. by using the techniques of an explicit criterion to determine the number of real roots of a univariate polynomial in ( [ 13 ], [ 73 ] ) ; b - net form of bivariate splines function ; discriminant sequence of polynomial ( cf. [ 13 ], [ 73 ] ) and the number of sign changes in the sequence of coefficients of the highest degree terms of sturm sequence, this paper determines the number of real intersection points two piecewise algebraic curves whose common points are finite. a lower bound of the number of real intersection points is obtained in terms of method of rotation degree of vector field

    大連理工大學博士論義:分片代數價線i片代數簇的若十m穴3 :利用楊路,張景中,侯曉榮在文獻v13 , 73 )中關於一元多項式實根的顯式判準,以及二元樣條函數的b網形式,多項式的判別序列和sturm序列的最高次數項系數序列的變號數,本文給出了兩個分片代數曲線的丈交點數(假設公共點是有限的)的計算公式。
