PVQC Physics 物理專業英文 Sp Lite vs BioCalc Lab

專業英文PVQC (Professional Vocabulary Credential)是一種行業或學科特定用途的專業英文(English for Specific Purposes, ESP)學習體系，依照學習層次的難易程度可分成: Fundamentals(基礎級), Specialist (專業級), 及 Expert (專家級)等三級。 本App軟體主要內容為科學類物理(Physics)的學科專業英文，難易程度為Specialist (專業級)，提供了物理(Physics)學科的關鍵單字(vocabulary)、關鍵詞(keywords)及關鍵句(key sentences)，約400至500個常用關鍵字詞。 本App軟體主要為提供初學者可直接使用，不須任何帳號不蒐集您的資料。請在主畫面點選[Start]進入，即可做練習。練習時，畫面右下角會出現[Authentication Code:OFF]，為正常狀態。 本App內共有六種練習測驗項目，每項測驗皆須完成20個題目。每次練習時，系統會依照設定、隨機挑選題目，共組成120個題目。 其中，[測驗1]的練習檢測時間為20分鐘、40分及格； [測驗2]至[測驗6]每個項目的練習檢測時間為10分鐘、70分及格。 以母語(L1,在此為中文)及英文(L2)的識讀與英語聽力(Reading and Listening)等方式交互做練習測驗。對物理英文關鍵詞彙的識別、聽力及拼寫(Spelling/Writing)，具有相當的學習效果。 與PVQC可配合使用的其他學習體系有：PELC專業英文聽寫能力, GQC文法聽寫能力, VQC一般英文單字能力等。

BioCalc Lab is a precise, professional bioinformatics calculator designed for molecular biology researchers, students, and lab technicians. CALCULATORS INCLUDED PCR Setup Build your PCR reaction table interactively. Add or remove reagents, set stock and final concentrations, choose units from a dropdown, and get an instant pipetting summary with exact µL volumes — including nuclease-free water fill. Dilution (C1V1 = C2V2) Solve for any of the four variables in the dilution equation. Enter three known values and the result updates instantly, along with a plain-language pipetting instruction. Molarity Calculate mass, amount (mol), volume, or concentration using molar mass. Supports multiple input paths — enter whichever values you know and the correct result is derived automatically. Primer Analysis Paste or type any 5'→3' primer sequence. Instantly see: - Length and base composition (GC / AT counts and GC%) - Melting temperature via Wallace rule and a simplified nearest-neighbor formula (50 mM Na⁺) - Four quality checks: GC content, length range, self-complementarity, and 3' hairpin risk - Reverse complement sequence DESIGN PHILOSOPHY BioCalc Lab follows a dark lab-aesthetic interface — deep navy background, teal accent readouts, and monospaced numeric displays — so results are easy to read at a glance at the bench. PRIVACY No account required. No data collected. All calculations happen on-device.
