The direct incorporation of U-13C glucose was estimated by the intensity increase of m/z to F(F was parent fragment, and n was the carbon number in the fragment), while the total isotope incorporation from the added 13C could be calculated according to the abundance ratio increment summation from m/z (Fa+1) through (Fa was the fragment containing all original skeleton carbons, and T was the carbon number in the amino acid molecule). The 13C enrichment in the target compound was expressed as atom percentage excess, and that of D-amino acid needed to be corrected by the coefficient of hydrolysis-induced racemization. The 13C enrichment reflected the carbon turnover velocity of individual amino acid enantiomers, and was powerful to investigate the dynamics of soil amino acids.

外加葡萄糖直接合成氨基酸的比例可利用质谱碎片的相对强度变化来评价（n为质谱碎片F中含有的碳原子数目）；而源于葡萄糖的13C同位素在氨基酸分子中的富集程度是所有同位素峰相对强度变化的总和。13C在目标化合物中的富集比例用原子百分超评价，D氨－基酸的APE还需进一步利用水解诱导的外消旋化系数校正。13C在目标化合物中的富集程度可反映各氨基酸手性异构体的碳循环速率大小，是研究土壤氨基酸动态变化的有力工具。

Allomorph: Any of the variant forms of a morpheme. For example, the phonetic s of cats, z of dogs, and z of horses and the en of oxen are allomorphs of the English plural morpheme.语素变体,语素的一种变体形式,如语音学的中之 s在 cats中,z在 dogs中,和 iz

A comparable function can be defined in terms of the digital transfer function using the polar variable z by defining HH = HH (1/z) which gives the magnitude-squared frequency response when evaluated around the unit circle, i.e., z = ejw.

解析复杂值函数的复变S是定义在此背景下，逼近抵达中的F ，结果是一个解析函数法郎的因子F款，这是理想的过滤器传递函数在矩形的变数。

Based on rain drop size distribution data measured in Qingdao, Guangzhou and Xinxiang, the radar reflectivity factor Z for spherical rain drops, the radar reflectivity factor Z〓 and differential reflectivity Z〓 for oblate ellipsoid rain drops have been calculated.

基于雨致交叉极化理论，提出了雨致交叉极化的二阶小变量近似方法以及新的雨致交叉极化预测模式，与其它模式和实验数据比较表明，该模式更能反映波的极化特征，较其它模式有一定的改进。

In this experiment, there was no significant difference between R and H treatment. The soil pondage of Z treatment was less than that of R and H, which indicated that Z treatment was disadvantageous to soil water infiltration under irrigation conditions because Z was covered by straw and had high density.

模式之间比较，旋耕和耙耕模式土壤贮水量差异不显著，免耕模式小于旋耕和耙耕模式，表明在灌溉条件下，免耕模式由于地表秸秆覆盖加之土壤表层容重变大，不利于土壤水分的下渗。

Z! z/ Z r6 o, d In "Salt of the Earth," a 1996 book of autobiographical and religious reflections based on interviews with German journalist Peter Seewald, the then Cardinal Joseph Ratzinger said he was automatically enrolled in the Hitler Youth as a seminarian but played no active part.

alt of the Earth，一本写于1966年的对宗教的一些反思跟思考的自传体回忆录，当时的红衣主教约瑟夫拉青格，在接见了一名德国记者彼得后，就无意识的以一个神职人员的身份成为了纳粹分子，虽然当时并没有发挥什么作用

Relative contents of four main cellular proteins corresponding to MALDI-TOF-MS peaks m/z 4466, m/z 6455, m/z 6514, and m/z 7772 were all found to be close correlated with the concentration of melamine, although their up- and/or down-regulations showed different patterns when the concentration of melamine changed. Support vector regression leave-one-out method, with the optimized polynomial kernel function and a poly-degree of 3, was chose to evaluate the correlation between the alteration of Tetrahymena pyriformis main proteins'relative contents and the concentration of melamine in the culture medium.

NaCl-tolerant clones of Z. sinica and Z. matrella (LRM and LCG, could retain a few green leaves at 7.5% NaCl for 3 weeks) and two sensitive clones of Z. matrella (HB and KE, showed 100% and near 100% leaf necroses in 3% NaCl) were used for this study. Plants were grown in nutrient solution supplemented with NaCl up to 3% under controlled conditions.
