自由傳粉 的英文怎麼說
中文拼音 [zìyóuzhuànfěn]
自由傳粉
英文
free pollination-
Open-pollinated progenies of such genotypes are raised separately.
將這種基因型的自由傳粉的後代分別播種。Selfing is inhibited by genetic self incompatibility and also by the fact that within a single flower the stigma is receptive before the anthes are ready to shed pollen.
由於遺傳上的自交不親和性以及花中柱頭只能在花粉準備撒粉以前接受花粉，因而防止了自交。The boiler pulverizing system adopt mainly steel ball milling coal machine and mill storage pulverizing system, because the system has characteristics, such as, strong coupling, great time lag and slow time change. the quantity of storage coal in the ball milling coal machine ca n ' t measure exactly. manpower operation or use conventional regulate intrument ca n ' t get often perfect control effect
鍋爐制粉系統大多採用鋼球磨煤機、中儲式制粉系統，由於該系統具有強耦合、大時滯、慢時變等特點，而且球磨機磨內存煤量難以準確測量，人工操作或用傳統的調節儀表往往難以達到理想的控制效果，普遍存在耗能高、自動控制困難等問題。The scc has the following advantages : remarkably reducing the noisy pollution and the worker s labor intensity in construction, deducing the rough surface or segregation because of missing - vibration or excessive - vibration in conventional construction, resolving the quality - defect problems resulting from lacking - vibration in the section of complex shapes and densely - packed reinforcement area. at the same time, large of industrial solid waste such as fly ash and blast furnace slag is utilized in the proportioning of scc. it is helpful in comprehensive utilization of resource and environment protection, so the scc belongs to " green concrete ", it is a branch of hpc which will be developed in the future
這種混凝土可以顯著降低混凝土施工中的噪音污染；大幅度減輕工人的勞動強度；減少傳統混凝土施工中因漏振或過振造成的麻面或離析；解決了配筋密集、結構復雜部位因振搗不足而造成的質量缺陷問題；同時，由於自密實混凝土在配製中，大量利用粉煤灰、高爐礦渣等工業固體廢棄物，有利於資源的綜合利用和生態環境的保護；從而被譽為「綠色混凝土」 ，是未來混凝土向高性能發展的方向之一。By use plc, system can complete function as follow : this auto - control system be applicable to the temperature and smoke and dust the deal the variety quick, control the process is difficult with the operation is ; by the temperature controlor can automatically follow to the wet tower " exit temperature, error in the ? 3 v including ; by to automatically spray fog to lower the electric resistance, with the function for full the electricity equipment accepting the dust ; because of adopting feedback closed loop, and come to a to respond to the speed quick, constant temprature control the accuracy is high ; because of adopting the sensors, and make the system circumstance to leak water quick ; system have many control parameter can set exit control temperature and adjust value low limit by key ; can communication with remote computer and have remote control
通過使用plc ，使該自控系統可以完成如下功能：適用於溫度及煙塵量變化快、控制過程難以操作的場合；通過溫控表自動跟蹤增濕塔出口溫度，誤差達到3以內；通過自動噴霧來降低粉塵比電阻，以此充分發揮電收塵器的作用；由於採取了閉環反饋迴路，達到了響應速度快，恆溫控制精度高；通過使用各種檢測傳感器，使得異常情況泄水快；該自控系統具有多套控制參數，增濕塔出口控制溫度及調節閥下限值可通過按鍵設定；可與上位機通訊，具有「現控遠控」功能。分享友人
