Effects of lower salinity on survival of wing oysterpteria penguin 低鹽度海水對(duì)企鵝珍珠貝存活的影響
Experiment on healthy culture of whiteleg shrimp penaeus vannamei in low salinity water 南美白對(duì)蝦兌淡健康養(yǎng)殖試驗(yàn)
On the characteristics of litopenaeus vannamei body length and weight growth at low salinity environment 低鹽度養(yǎng)殖的凡納濱對(duì)蝦體長(zhǎng)和體重的增長(zhǎng)規(guī)律
Methods : firstly , tetraselmis tetrethele had been cultured for ten days under stresses of nutrients limitation , light limitation , lower salinity and higher salinity , while normal condition was control 方法:將四列藻置于營(yíng)養(yǎng)限制脅迫、光限制脅迫、低鹽和高鹽脅迫下培養(yǎng)10天,以正常條件作對(duì)照。
During the periods of 12ka , 60ka , 118 - 130ka , the decreasement of summer monsoon resulted in the decreasement of sw monsoon , then correspondingly , the less high salinity water mass make this area low salinity 在12ka 、 60ka 、 118 - 130ka 、 240 - 250ka幾個(gè)時(shí)期由于夏季季風(fēng)的減弱,引起西南季風(fēng)流減少,從西邊過(guò)來(lái)的高鹽度水團(tuán)的減少使該區(qū)鹽度降低。
In addition , at the ultrastructure scale , there are evident differences in chloroplast . in lower salinity ( 50 , 100mm ) , the lamellae of stoma and grana in some chloroplast expanded lightly ; the boundary of the chloroplast was dim 在50 、 100mhnacl處理下,細(xì)胞中有些葉綠體的基質(zhì)、基粒片層稍有變形,被膜界限出現(xiàn)模糊現(xiàn)象,類囊體出現(xiàn)膨大。
Green crab happy event is fed carrion , also prey alga , be in at the shallow sea of warm and low salinity habitat the river that has briny infiltration emerges channel depression yi ke lives for a long time , green crab is one of crab of important edible sea 青蟹喜食腐肉,也捕食藻類,棲息于暖和而低鹽度的淺海在有海水滲入的河涌溝洼亦可長(zhǎng)期生活,青蟹為重要食用海蟹之一。
Based on distribution of deposits and types and characteristics of mineralization , two mineralization zones could be divided . from west to east they are yongpingchangjie - shuixie - nanjianxinmin middle - high temperature copper - cobalt mineralization zone and zijinshan - maanshan - bijiashan middle - low temperature au - as - sb - hg mineralization zone . the types of deposits in the former are high - middle temperature and middle - low salinity hydrothermal copper - cobalt deposits , and high - middle temperature and mid 進(jìn)一步揭示出本礦化區(qū)成礦元素與成礦溫度在平面上的分帶性,西南部以cu - co - au的中溫-中高溫成礦為主,東部及東北部以低溫-低中溫au - sb - as - hg成礦為主,平面上的這種分帶,可能也指示垂直方向的分帶。
The company is a joint - stock enterprise , it possesses 266 million login capital and 416 million permanent assets , undertakes exploitation , the company have 426 employees , the proportion of all kinds of professional technology personnel in all employees is 30 % , processed and sell of trona . and is in virtue of high purity , low salinity , excellent whiteness and less impurity , after the second item carry our point , the company will produce 700 thousand ton production every year 安棚公司是一家股份制企業(yè),注冊(cè)資金26600萬(wàn)元,固定資產(chǎn)41600萬(wàn)元,現(xiàn)有在冊(cè)員工426人,各類專業(yè)技術(shù)人員占30 ,主要從事天然堿的開(kāi)采、加工,二期達(dá)產(chǎn)后年產(chǎn)能力可達(dá)70萬(wàn)噸,產(chǎn)品純度高、鹽分低、白度好、雜質(zhì)少。
