设$f$是权重$k$和层$N的原始尖点形式,$设$\chi$是与$N,$互质的导体的狄利克雷特征,并设$\mathfrak{L}(f\otimes \chi, s)$表示$\log L(f\otimes \chi, s)$或$(L'/L)(f\otimes \chi, s)$。$在本文中,我们研究当 $\chi$ 或 $f$ 变化时 $\mathfrak{L}$ 的值。首先,对于准字符 $\psi\colon \mathbb{C} \to \mathbb{C}^\times$,我们找到平均 $\mathrm{Avg}_\chi \psi(L(f\otimes\chi, s)),$ 的极限,当 $f$ 固定并且 $\chi$ 通过素导体趋于无穷大的字符集变化时。其次,我们通过建立上述极限函数的解析性质来证明 $\mathfrak{L}(f\otimes \chi,s)$ 的值的均分结果。第三,我们研究当$f$遍历给定权重$k$和级别$N\到\infty的原始尖点形式集合时调和平均$\mathrm{Avg}^h_f \psi(L(f, s)),$的极限。$大部分结果是在$L(f\otimes\chi, s)的广义黎曼假设条件下获得的。$
Let $f$ be a primitive cusp form of weight $k$ and level $N,$ let $\chi$ be a Dirichlet character of conductor coprime with $N,$ and let $\mathfrak{L}(f\otimes \chi, s)$ denote either $\log L(f\otimes \chi, s)$ or $(L'/L)(f\otimes \chi, s).$ In this article we study the distribution of the values of $\mathfrak{L}$ when either $\chi$ or $f$ vary. First, for a quasi-character $\psi\colon \mathbb{C} \to \mathbb{C}^\times$ we find the limit for the average $\mathrm{Avg}_\chi \psi(L(f\otimes\chi, s)),$ when $f$ is fixed and $\chi$ varies through the set of characters with prime conductor that tends to infinity. Second, we prove an equidistribution result for the values of $\mathfrak{L}(f\otimes \chi,s)$ by establishing analytic properties of the above limit function. Third, we study the limit of the harmonic average $\mathrm{Avg}^h_f \psi(L(f, s)),$ when $f$ runs through the set of primitive cusp forms of given weight $k$ and level $N\to \infty.$ Most of the results are obtained conditionally on the Generalized Riemann Hypothesis for $L(f\otimes\chi, s).$
