  1. This paper deriving the theory work inflection point in the static stage characteristics curve of small measurement range linear dimension measurement. by the way of high pressure and back pressure pneumatic measure and designed the parameter of the mainly and measure spray head, which are the key component in the spray head - baffle pneumatic sensor. the different groups for the main - spray head and the measure spray head, will effect the dynamic and static stage characteristic parameter. the author have done contrast experiment and optimization design to test and verify the theory derivation whereby made the rang of show valve of pneumatic measure system measure range up to 40 u m, the sensitivity up to 100mv / u m, resolution up to 0. 05 p m, the uncertainly of measure is less than 0. o2 u m, satisfaction of requirement of groups the carboy hatch thickness size precise measure of soft shims

    對高壓背壓式氣動測量用於小量程線性尺寸測量的靜態特性曲線的理論工作拐點進行了推導，對氣動測量系統中的噴嘴-擋板型氣動傳感器中的關鍵部件? ?主噴嘴和測量噴嘴的參數進行了理論設計，對主噴嘴和測量噴嘴的不同組合，將影響測量系統靜、動態特性指標的噴嘴參數進行了對比實驗和優化設計，並通過實驗驗證了理論推導，從而使氣動測量系統量程的示值范圍達到40 m ，靈敏度達到100mv m ，解析度達到0 . 05 m ，測量不確定度小於0 . 2 m ，滿足了壓縮機缸蓋軟體墊片厚度尺寸精密測量分組的要求。
  2. At last, these functions are used to advance sha - 1, and a new hash function called csha is proposed. unit 4 : at present, cryptography hash algorithm for applications such as digital fingerprinting of messages, message authentication, and key derivation is commonly iterative processed which hash inputs of arbitrary length by processing successive fixed - size blocks of the input. the iterative process is commonly serial construction

    在系統分析了雜湊函數機制后，我們利用j . seberry等人提出的方法，構造出了同時滿足平衡性、高度非線性及嚴格雪崩特性的並且容易實現的雜湊輪函數，並利用這些雜湊輪函數，在原sha - 1雜湊函數的基礎上，設計出了新的雜湊演算法csha 。
  3. Implements password - based key derivation functionality, pbkdf2, by using a pseudo - random number generator based on

    的偽隨機數生成器，實現基於密碼的密鑰派生功能（ pbkdf2 ） 。
  4. In a password - based key derivation function, the base key is a password and the other parameters are a salt value and an iteration count

    在基於密碼的密鑰派生功能中，基本密鑰是一個密碼，其他參數是一個salt值和一個迭代次數。
  5. You can use pbkdf2, a password - based key derivation function, to derive keys using a pseudo - random function that allows keys of virtually unlimited length to be generated

    您可以使用pbkdf2 （一種基於密碼的密鑰派生函數） ，利用偽隨機函數來派生密鑰，這種偽隨機函數允許生成長度幾乎不受限制的密鑰。
  6. This attack is made much more difficult by the introduction of random bytes at the end of the password before the key derivation

    在密鑰導出之前在密碼末尾引入隨機位元組將使這種攻擊非常困難。
